This is the motor and control circuit for my setup.

 

The main function here is to provide super-slow motion to the dolly. This is achieved with both a gear box and a pulse width modulation (PWM) circuit.

 

I used a Tamiya gearbox for my gearing ($15). My particular gearbox allows for 6 different speeds by swapping out gears. In practice however, the speed is more or less fixed as it means taking apart the whole thing to change out the gears. I have mine set on the lowest speed (using all six gears that came with the kit). This gave me the slowest output, and great torque. Further speed control was achieved through the PWM circuit.

 

The PWM circuit helps reduce the motor speed even more and provides speed control through the knob on the left. The circuit slows down the motor by breaking up the voltage into short pulses. By changing the width (or duration) of those pulses, you can change the average voltage to the motor, thus changing the speed. All the PWM parts were picked up from Radio Shack for about $20. Eventually this should all probably be soldered down, but for now it still on the breadboard.

 

I learned about PWM circuits from the following video (nerd-alert warning): www.youtube.com/watch?v=YmPziPfaByw

 

The pen on the right is used to wind up my string. It is not very high tech, but it was free and has served me very well thus far.

 

You can also see the aluminum guides I have mounted on track edges to keep my dolly inline. These were home depot items and cost me about $10. Most of the wood here is scrap, but I did spend around $12 for a 6' length of 1x8 for the track itself.

 

in painting, but it is very hard to talk about. There is almost nothing you can say that holds up as a generalization, because it depends on too many factors: size, modulation, the rest of the field, a certain consistency that color has with forms, and the statement you're trying to make.

another victory on ebay. it was museum quality, as mint as I could imagine from this era. it weighs a ton and is so full of metal, it rivals the HP funct generator that I also recently bought.

 

the only thing wrong with this one was that the top 'a' segment of the leds were intermittant. 2 hours of troubleshooting led me to the cause: the one controller chip inside was in a very cheap IC socket and some pins were not making good contact (after all these decades). I could not get the socket to spring back BUT there was enough clearance inside to let me stack another machine-pin socket on top of the cheap one. this mated well with both the chip and the old socket. problem solved!

 

the display is a bit of fun; I was playing with the AM modulation and the scop triggering and I could get the display to show some of the amplitude modulated waves, in an interesting super-imposed way.

 

also, the SIZE of that function generator! its about the same width AND depth as the scope! what a monster ;)

 

My Zorki 1/Industar-22 is a joy to use. It's fun, small and operates like a Swiss watch. Only trouble is, it doesn't always take the best of photos. After some comparative shots of identical scenes between the Industar-22, Industar 26M and Industar-61 L/D, and some peering through the lenses with the Mk 1 eyeball, I've come to the conclusion that the lens is probably not generally useable. Although the I-22 is slightly sharper than the other two lenses, it produces flat, dull images.

 

The photo above, of Rutland Square in Edinburgh, shows what's wrong. The cast iron detail in the bench seat is accuragely rendered, but the white car above has a halo around it, visible against the dark stonework behind. The problem seems to be due to scratches and hazing on the surface of the lens elements which is scattering light from other parts of the scene onto the image plane --- producing flaring around bright objects and generally giving a noise-like background glow over the whole image. I guess in MTF terms the scratches attenuate the curve right across the frequency range.

 

The Zorki has also given me a few scratches on the surface of my (old) glasses. When I look at a bright white patch through the scratched area I see the same halo effect seen in this photo.

 

In part the scratches are cleaning marks on the front and rear, but also I think they are due to the cement in the rear doublet breaking down.

 

It's still a fun camera, but I think I'll have to start using a different lens.

This is a close-up shot of the circuit layout.

 

This project uses an Arduino to drive a miniature "segway" balancing robot.

 

A pair of Lego Mindstorm NXT motors are used to drive the robot wheels. An Arduino is used to control the motors. An ADXL335 3-axis accelerometer is used to determine robot orientation. An L293D H-Bridge is used to allow the Arduino to interface with the Lego NXT motors using pulse-width modulation signals. A proportional-integral-derivative (PID) algorithm was used to determine the logic for wheel movement. Programmed in C++.

 

Unfortunately, the robot required "human assistance" to stand up on its own for any length of time. I wish I had a bit more time on this project to continue tweaking the PID algorithm to improve this.

Having owned the 2008 Kona Sutra for ten months, and just completed the first chain/cassette replacement, I thought it was about time for a long term review, to give other people an idea of what living with the Sutra has been like. My previous post explains why I chose the Sutra - I came up with what I thought was an impossibly eclectic list of requirements from a bicycle, and the Sutra ticked every single box.

  

Here's some specs, for the statophiles out there: Frame size C54cm Frame tubing Dedacciai COM 12.5 Butted Cromoly Fork Kona P2 700c TB Disc w/Lowrider Headset TH Crankarms FSA Gossamer MegaExo Chainrings 30/39/50 B/B FSA MegaExo Pedals Shimano PD-M520 SPD - Silver Chain Shimano HG53 --> Shimano HG93 XT Freewheel Shimano Deore (11-32, 9 Spd) --> Shimano XT M760 (11-32, 9spd) F/D Shimano Tiagra Triple R/D Shimano XT Shadow Shifters Shimano Bar-Con Handlebar FSA RD30 0S Stem FSA OS-190LX Grips Velo Wrap with Gel Brakes Avid BB7 Road Disc Brake Levers Shimano BLR-600 Front Hub Shimano M525 Disc Rear Hub Shimano M525 Disc Spokes DT Stainless 14g Tires Continental Contact 700 x 32C --> Schwalbe Marathon Plus 700x38c Rims Mavic A 317 Disc Saddle Selle Italia XO SE --> Brooks B17 Seatpost FSA SL-280 Seat Clamp Kona Clamp Rear Rack Tubus Logo Panniers Bikebins Computer Sigma DTS 1606 L Fenders SKS Chromoplastic

  

My primary (i.e. 99% of the time) use of the Sutra has been for commuting. I have covered over 2700 miles (4500km) in the time I have owned it. My commuting route through London is pretty tough on bikes - the roads south of the Thames are awful and full of potholes, through the City there is broken glass all over the place, and further north of the river there are speedbumps everywhere. When I first got the Sutra she was wearing Continental Contact tyres, and they were pretty poor for commuting. They punctured easily and transmitted the bumpiness of the road right up into my forearms. Not much fun. After one puncture too many I replaced the tyres with Schwalbe Marathon Pluses, in their largest diameter, and the difference was marked. The increased volume of air provides a lot more cushioning for the arms, and I have not had a single puncture yet, despite having pulled 6mm long pieces of glass out of the tyre surfaces. The tyres are relatively heavy, but then so is the rest of the bike, and extra weight makes you stronger!

  

The original rear rack was pretty flimsy, and it did not allow the attachment of the Bikebin panniers I bought to try and add some rigidity. I ended up having to angle grind chunks out of the rack to fit the panniers, which can't have improved their structural integrity. After a month of experiencing the odd sensation of the bike wagging its tail whenever I stood up to pedal hard, I bit the bullet and upgraded the rack to a Tubus Logo. It was a tight fit with the rear disc brake, but the difference was immense. Gone was the sensation of a jelly-like bike, to be replaced by a sensation of rigid stability. Whilst the rack was expensive, it made all the difference, and I would highly recommend it.

  

Speaking of the brakes, they have saved my life on more than one occasion, usually when a Taxi decides to perform an emergency stop to pick up a fare. The brakes stop consistently in all conditions, and so far I have not had to replace the pads, althoguh I think it will be time to do it soon. Not bad considering I have travelled almost five thousand kilometres in all weathers in the stop-start conditions of London. I was concerned that the brakes might be too powerful, but the modulation provided by the levers and the flex in the arm of the brake means that whilst the power is there if necessary, you have a lot of control over it. There is some disc drag, but this is owing more to my laziness than the brakes themselves, and seems to have little impact on cruising speeds.

  

Using the bike in all conditions has been excellent. The all-over fenders (something I have never fitted to a bike previously) really keep the rain off and eliminate spray from the road. I had to saw a bit of the front fender off to fit it over the larger tyres, and a little bit off the rear for the same reason, but after the modification they have been flawless.

  

I had heard reports of spokes snapping, and nothing happened to me until recently, when I noticed a detached spoke whilst replacing the rear cassette. I had no idea how long the spoke had been damaged for, and replaced it myself. The rear wheel is slightly askew, but it does not foul on anything, which is good considering the small tolerance between it and the fender. To be fair, I have been jumping off kerbs and sometimes it is impossible to miss a massive hole in the road when you are in busy traffic. An upgrade I am considering is a stronger rear wheel, although it is not pressingly urgent.

  

The ride of the bike is super smooth, and certainly not anything like the road bikes I am used to. I use my other road bike for triathlons, and whilst it is a lot more nimble, it is much less comfortable. The Sutra is comfortable all day long, owing in no small part to the Brooks B17 saddle, which took about two thousand miles to properly break in! It was worth it though - sitting on the bike is like sitting in an armchair (albeit a very odd armchair, but an armchair nonetheless). I tend to cruise at about 20mph on her, and my 10.5 mile commute to work takes about 37 minutes. I have started seeking out hills in preparation for some touring of Wales, and the sutra certainly loves to climb. The aggressive, mountain-bike-like frame geometry no doubt assists in this, and is confidence inspiring when climbing and descending. The bar-con shifters were a novelty for me, but they make a lot of sense, especially if replacement shifters were needed on a tour. There are even bosses on the downtube to fit truly old-school shifters in an emergency.

  

The weight of the bike was a shock initially - weighing in at 15kgs without the accessories, she weighs significantly more than my Specialized Hardrock mountain bike, which is saying something! Over time I have become accustomed to the weight, and now it feels normal. The main advantage of this is that when I ride anything else, it feels super light and goes very rapidly. This makes this bike an ideal training steed.

  

In conclusion, I have found a lot to love about the Kona Sutra - she's tough, strong and surprisingly fast. There were some niggles about fitting add-ons, but they were all easy to overcome, and the result has been a reliable bike that I think will keep delivering for years.

Review by Joe Viglione

Your Twist Party is an interesting and fun album from Chubby Checker, starting off with his classic rendition of Hank Ballard's "The Twist," and continuing with "twist"-style arrangements of popular tunes of the era. Fats Domino's "Blueberry Hill" gets the same treatment as Bill Haley's "Rock Around the Clock" — sung "Twist around the clock" here. Picture the Ramones giving their trademark power-chord treatment to cover songs their fans could identify with, and you get the spirit at play on Your Twist Party. "Whole Lotta Shakin' Goin' On" gets a "twist" mutation, while Chubby adds some Big Bopper/Jerry Lee Lewis ad libs to Kal Mann's "Mister Twister." Elvis Presley's "Hound Dog" receives a nice modulation — and an adaption as well — "You ain't nothing but a hound dog/twistin' all the time/little sister you're a twister and you ain't no friend of mine." Mann & Appell create the "Mexican Hat Twist" out of the "Mexican Hat Dance," just as Kal Mann may have inspired the Beach Boys with his "Twistin' U.S.A." (years before the Fat Boys brought a common denominator to both camps by charting on separate occasions with Chubby and the Beach Boys ). Lerner & Loewe's "I Could Have Danced All Night" works remarkably well in this format, and is a highlight of this collection. Though the obsession with the dance craze may be a bit much, this is also the record's charm, and the album features three of Checker's biggest songs with "Let's Twist Again," "The Hucklebuck," and "The Twist," while giving a sly nod to the singer's first hit from 1959, "The Class," where he imitated some of the people he covers here.

  

Messier 3 (also known as M3 or NGC 5272) is a globular cluster of stars in the northern constellation of Canes Venatici. It was discovered by Charles Messier on May 3, 1764,[7] and resolved into stars by William Herschel around 1784. Since then, it has become one of the best-studied globular clusters. Identification of the cluster's unusually large variable star population was begun in 1913 by American astronomer Solon Irving Bailey and new variable members continue to be identified up through 2004.[8]

Many amateur astronomers consider it one of the finest northern globular clusters, following only Messier 13.[1] M3 has an apparent magnitude of 6.2,[4] making it a difficult naked eye target even with dark conditions. With a moderate-sized telescope, the cluster is fully defined. It can be a challenge to locate through the technique of star hopping, but can be found by looking almost exactly halfway along an imaginary line connecting the bright star Arcturus to Cor Caroli. Using a telescope with a 25 cm (9.8 in) aperture, the cluster has a bright core with a diameter of about 6 arcminutes and spans a total of 12 arcminutes.[1]

This cluster is one of the largest and brightest, and is made up of around 500,000 stars. It is estimated to be 8 billion years old. It is located at a distance of about 33,900 light-years away from Earth.

Messier 3 is located 31.6 kly (9.7 kpc) above the Galactic plane and roughly 38.8 kly (11.9 kpc) from the center of the Milky Way. It contains 274 known variable stars; by far the highest number found in any globular cluster. These include 133 RR Lyrae variables, of which about a third display the Blazhko effect of long-period modulation. The overall abundance of elements other than hydrogen and helium, what astronomers term the metallicity, is in the range of –1.34 to –1.50 dex. This value gives the logarithm of the abundance relative to the Sun; the actual proportion is 3.2–4.6% of the solar abundance. Messier 3 is the prototype for the Oosterhoff type I cluster, which is considered "metal-rich". That is, for a globular cluster, Messier 3 has a relatively high abundance of heavier elements.[9]

The Arp Quadra is a rare and beautiful polyphonic (kind of) and analog beast. The machine combined pre-existing products: the Omni, Odyssey, a Solina-esque string unit, a phase shifter and a divide-down organ with ADSR, and a 4075 24 db low pass filter into one box. It has four sections. Bass is on the bottom two octaves, has two unison bass circuits (electric and string), with AR and a single pole low pass filter and a related AD envelope for cutoff. A string section is similar to the ARP Omni. Poly Synth, and a two voice Lead Synth similar to the Odyssey and a five way mixer with four unit outputs, a stereo pair, a line mono and an XLR out.

There are 16 memory locations, but these do not provide storage of slider settings. The 8048 microcomputer and 128k of CMOS SRAM memory recalls 16 stored sets of on/off decisions about which waveforms and modulations are turned on in each of the four sections, and lead intervals. Using LEDs the player is visually directed to the sliders critical to the sound selected but their settings are not updated.

The Quadra was not a truly polyphonic. It used divided-down circuits for the Omni-style string section, including ADSR, LFO, filter and VCAs for the Polyphonic Synth section. Both Polyphonic Synth and string sections share the hollow wave button which changes waveforms for both sections.

It has a simple and useful arpeggiator for the lead section and memorizes intervals between the two lead VCOs. Vibrato, LFO and a fast square wave trill can be added to the arpeggiation. Very unusual is the two independent portamento rates for each VCO, whether locked together or in interval mode. This is useful in either multiple or single trigger mode. Huge sweeping sounds meeting in unison is very fun.

Outstanding is the rich lush phase shifter which creates stereo and includes harmonic resonance. Also uncommon is the ability to deploy sample and hold within the phaser. The sound is similar to the chorus of the Solina, though many users avow that the Quadra due to its sonic texture and modulation controls is the richest string machine ever made.

The top three octaves of the keyboard have a mechanical touch sensor that can either pitch bend or impact brilliance and filter. Unique is the flat pedal feature which allows pedaling to dip individual notes and chords a semitone below so they rise to pitch with the envelope’s attack.

Extensive CV/Gate facilities allow two external sequencers to independently control both the bass and the lead. It is capable of four independent outs, stereo out, mono, and mono XLR but hidden in the quad outs is TRS facility for processing and returning effects on individual parts of the four sections to be recombined with external audio at a built-in mixer, which includes an internal compressor circuit. Like all ARP synthesizers of this series (2800) its true character opens up with selective use of the optional foot pedals.

The Quadra uses the typical ARP orange and black color scheme of the company's later years including the orange leather end pieces and the clean XLR out for DI console recording.

Prague Castle (Pražský hrad)

For more than a thousand years, has the Prague Castle been an important symbol of the Czech state. Founded in the 9th century, it became the permanent seat of the Czech rulers and, most recently, also of the Presidents. One of the largest castle complexes in the world consists of palaces, offices, churches and fortification buildings, gardens and picturesque corners. The castle covers an area of ​​45 hectares. The unique view to the Prague Castle is one of the most amazing panorama views in the world.

Prague Castle is the most important folk-cultural and historical monument, and is the symbol of the more than one thousand years of development of the Czech and all-Czech states. It is a monumental symbol of the palace, church, fortification, official and residential buildings which represent very valuable monuments, included in all style epochs. It covers an area of ​​45 hectares, was the seat of the Bohemian princes, kings and emperors, and since the Republic was founded in 1918, it was also the residence of the presidents. Since 1962, the Prague Castle has been known for its archaeological discoveries.

History

The initial phases of the Prague Castle are connected with the first historically documented Přemyslid Bořivoj (Bořivoj I (Czech pronunciation: [ˈbɔr̝ɪvɔj], Latin: Borzivogius, c. 852 – c. 889) was the first historically documented Duke of Bohemia from about 870 and progenitor of the Přemyslid dynasty.] The Duchy of Bohemia was at those times subordinated to Great Moravia.). This one transferred in the 80s of the 9th century his original seat from Levý Hradec to the place where on the raised spot above the river Vltava/Moldau already existed a Slavic castle and was very well situated.

The first princely palace apparently only consisted of wood. The first stone building and the oldest Christian sanctuary was the Virgin Mary Church. Its remains have been found between the Second Courtyard and the Bastion garden (original name of the garden: Na Baště). This Bořivoj church was soon reconstructed by the prince Spytihněv I, who was buried here in 915. The second church in the castle was the St. George Basilica founded by Prince Vratislaus I. The next Přemyslide, Prince Wenceslas (Saint), the third sanctuary - the St Veit Rotunda - in the twenties of the 10th century nearby had built which in the 11th century by Prince Spytihnev II was transformed into a huge basilica.

In 973, when the bishopric was established in Prague, the castle was not only the seat of the head of state, but also the seat of the Prague bishop, the highest representative of the church. At the same time arose the first monastery in Bohemia at St. George's basilica.

In the 10th century the castle occupied an area of ​​about 6 ha. In the Romanesque epoch the former fortress, especially after the year 1135 thanks to Soběslaus I, as the stony princely palace and the new masonry fortified with some towers were erected, was turned into a fortified medieval castle. Of the towers is the eastern blacktower best preserved.

Very significantly the Gothic period in the appearance of Prague Castle intervened, most of all Charles IV (1346 - 1378), who, with his father, John of Luxemburg (1310 - 1346), obtained from the pope the promotion of the Prague bishopric to the archbishopric and laid the foundations for the construction of St. Vitus Cathedral. Under Charles IV, the castle for the first time was turned into the imperial residence. Charles IV the defense of the Prague Castle had consolidated, the Royal Palace with the Chapel of All Saints he rebuilt generously. The roofs he had covered with gilded plates, which were the foundation for the binding of words "Golden Prague". Since 1382, Bohemian rulers ceased to occupy the Prague Castle for more than 100 years. The royal court was moved to the place of today's Community hall and back to the Prague castle it came only in 1483 under Wladislaus from the Jagiellonian dynasty.

Although the ruler already in 1490 moved to Ofen (Buda), he had the Prague castle renovated in the late Gothic style under the supervision of Benedikt Ried. He was the master builder of the magnificent Vladislav Hall, the largest secular vaulted room of the then Europe, with which the first Renaissance signs came to Prague. He carried out major construction works, including the construction of a new masonry, the defensive towers and the expansion of the Royal Palace. At his time, the Gothic died away and a new architectural style, the Renaissance, gradually prevailed.

The direct influence of the Italian art on the new style was most frequently observed in Prague under the reign of Ferdinand I (von Habsburg) and after his departure from Prague under the influence of the governor Ferdinand of Tyrol. At that time, the medieval castle was converted into a comfortable Renaissance castle with gardens. The typical Italian architecture of the Royal Pleasure palace arose in the northern King's garden.

For a large building activity in 1541 contributed a fire devastating the castle objects as well as the surrounding area quite a lot. Within the framework of the restoration, both the housing estates and the church buildings were rebuilt. Under the reign of the first Habsburgs, nobility palaces were added to the castle grounds (for example, the Pernstein Palace - later Lobkowicz Palace, Rosenberg Palace and others). Horse stable buildings were built in the north-west.

Under the reign of the Emperor Rudolph II (1576 - 1611), the Renaissance and Mannerism transformation of the castle, which for the second time became the center of the empire, and especially the center of European culture and science, reached its peak. On the second courtyard, new rooms were built for the collections of Rudolph - the new (now Spanish) hall and the Rudolph gallery. Also arose the connection tract between the northwestern and the southwestern part of the castle. Just here the famous Kunstkammer (Art chamber) and other rooms for Rudolph's collective activities were located. Additionally further horse stable properties were built for his rare Spanish horses. During the Rudolph times also the foundation stone of the famous Golden Alley was laid. Laboratories of the Rudolph-Alchymists were supposed to have been in the Powder tower above the Hirschgraben (Deer's ditch). The castle suffered again considerable damages when it was occupied by the Saxon army in 1631 and by the Swedes in 1648 not only was occupied but also plundered. After the Thirty Years' War, the Habsburgs did not care too much about the Prague royal seat.

Only Maria Theresia carried out an extensive reconstruction of the Prague Castle from 1755 - 1775 into a representative castle complex. The reason for the massive construction action were war damages, caused by the intense bombing of the castle during war conflicts at the beginning of her reign. The reconstruction was designed by the Viennese architect Nicolo Pacassi, who also planned the first courtyard with the monumental entrance gate. From the time of the Theresian reconstruction stems also the chapel of the Holy Cross on the 2nd castle forecourt and other buildings, especially the noblewomen institute. The south wing he imprinted the uniform monumental late Baroque facade of a representative seat. His plans influenced by Viennese Rococo and French Classicism the builders Anselmo Lurago, Anton Kunz and Anton Haffenecker brought into life.

In the 19th century, the castle fell into ruin, in several objects after the Josephine reforms the army settled. In connection with the stay of Ferdinand I the Good in the castle after his abdication in 1848 and further in connection with the preparation for the coronation of Franz Joseph I in the sixties it came to building modifications of several objects. After 1859, when the community for the completion of St Veit cathedral emerged, began first the repair, and then, under the influence of the architect Joseph Mocker, the work on the actual completion of St Veit's cathedral was started, completed in 1929.

In the years 1920 - 35, carried out extensive regulations of the Prague Castle as the seat of the Czechoslovak President the great Slovenian architect Josip Plečnik, who masterfully combined the valuable historical space with modern civilization claims. His modifications mainly concerned the 1st and 3rd court, the southern gardens of the castle, the fourth forecourt with the Bastion garden as well as numerous interiors. He created e.g. the pillared hall, private rooms of the presidential residence, including the Masaryk workroom. His pupil, Otto Rothmayer, brought to an end the incomplete solutions of some castle interior spaces after the Second World War in comparable quality.

In 1936, Pavel Janák and after him, in 1959, Jaroslav Fragner became castle architect.

After the year of change of 1989, the Prague Castle was opened to the public in many places. During the term of President Havel, at the castle it came to modulations of the interiors and to the expansion of two new entrances into the second courtyard after the project of the creator and designer Bořek Šípek. The puncture through the rampart of the Powder bridge in Hirschgraben was rewarded with a significant prize (Arch. Josef Pleskot). Also interesting is the modern greenhouse of the world-famous architect Eva Jiřičná. The Georgian Square (Jiřské náměstí) was re-paved and modulated. The Mosaic of the Last Judgment was renovated in collaboration with the specialists from the Getti Institute. In 1990, the Prague Castle was solemnly illuminated and this situation lasts from dusk to midnight until today. In the main tourist season, the lighting time even lasts an hour longer until 1 o'clock. The tradition of electric lighting, but on a much smaller scale, began in 1928, when the lamps were installed for the 10th anniversary of the elevation to a Republic. A little bit the present daylight resembles of those from the end of the sixties, but today it is much more detailed and in communist times it was only switched on at solemn occasions. At that time, illuminative days were state holidays or significant day of republic, which, however, did not lack recognition from the communist point of view.

In recent years the reconstruction and renovation work has been developed in many buildings of the castle and a considerable attention has been devoted to the archaeological investigation, which has been going on since 1925 and has brought many insights into the history of the castle. The investigation as well as the renovation of the individual rooms and objects is motivated by the idea of ​​invigorating them as much as possible by making them accessible to the public.

 

Prager Burg (Pražský hrad)

Die Prager Burg ist seit über tausend Jahren ein bedeutendes Symbol des tschechischen Staates. Gegründet im 9. Jahrhundert wurde sie zum ständigen Sitz der tschechischen Herrscher und zuletzt auch der Präsidenten. Einer der größten Burgkomplexe weltweit setzt sich aus Palästen, Amts-, Kirchen- und Fortifikationsgebäuden, aus Gärten und malerischen Ecken zusammen. Die Burg erstreckt sich auf einer Fläche von 45 Hektar. Der alleinige Blick auf die Prager Burg stellt einen der überwältigendsten Panoramablicke der Welt dar.

Die Prager Burg ist das bedeutendste Volkskultur- und Historiedenkmal, sie ist das Symbol der mehr als eintausendjährigen Entwicklung des böhmischen sowie gesamttschechischen Staats. Es ist ein monumentales Symbol der Palast-, Kirchen-, Fortifikations-, Amts- und Wohngebäude, die sehr wertvolle Denkmäler darstellen, einbezogen auf alle Stilepochen. Sie erstreckt sich auf einer Fläche von 45 ha, war der Sitz der böhmischen Fürsten, Könige und Kaiser und seit der Republikentstehung im Jahre 1918 war sie auch die Residenz der Präsidenten. Seit 1962 steht die Prager Burg mit ihren archäologischen Funden als bekanntester.

Geschichte

Die Anfangszeiten der Prager Burg sind mit dem ersten historisch belegten Přemysliden Bořivoj verbunden. Dieser übertrug in den 80er Jahren des 9. Jahrhunderts seinen ursprünglichen Sitz von Levý Hradec an den Ort, wo auf der erhabenen Stelle über der Moldau eine slawische Burgstätte bereits bestand und sehr gut gelegen war.

Der erste Fürstenpalast bestand offenbar aus Holz. Der erste Steinbau und das älteste christliche Heiligtum war die Jungfrau Maria Kirche. Ihre Reste wurden zwischen dem II. Vorhof und dem Basteigarten (Originalname des Gartens: Na Baště) gefunden. Diese Bořivoj-Kirche wurde durch den hier im Jahre 915 beigesetzten Fürsten Spytihněv I. bald umgebaut. Die zweite Kirche im Burgraum war die vom Fürsten Vratislaus I. gegründete St. Georg Basilika. Der nächste Přemyslide, der Fürst Wenzel (der Heilige), ließ in der Nähe in den 20er Jahren des 10. Jahrhunderts das dritte Heiligtum - die St. Veit Rotunde - bauen, die im 11. Jahrhundert vom Fürsten Spytihněv II. zu einer gewaltigen Basilika umgebaut wurde.

Im Jahre 973, als in Prag das Bistum gegründet wurde, war die Burg nicht nur der Sitz des Staatsoberhaupts, sondern auch der Sitz des Prager Bischofs, des höchsten Repräsentanten der Kirche. Zu demselben Zeitpunkt entstand an der St. Georg Basilika das erste Kloster in Böhmen.

Im 10. Jahrhundert nahm die Burg eine Fläche von ca. 6 ha in Anspruch. In der romanischen Epoche wurde die einstige Burgstätte, insbesondere nach dem Jahr 1135 dank Soběslaus I., als der steinige Fürstenpalast und das neue mit einigen Türmen verstärkte Mauerwerk aufgebaut wurden, zu einer festen mittelalterlichen Burg umgebaut. Von den Türmen ist der östliche Schwarzturm am besten erhalten.

Sehr bedeutend griff ins Aussehen der Prager Burg die Gotikzeit ein, insbesondere Karl IV. (1346 - 1378), der mit seinem Vater Johann von Luxemburg (1310 - 1346) vom Papst die Beförderung des Prager Bistums zum Erzbistum erwirkte und den Grundstein für den Bau der St. Veit Kathedrale legte. Unter Karl IV. wurde die Burg zum ersten Mal zur Kaiserlichen Residenz. Karl IV. ließ die Verschanzung der Prager Burg festigen, den Königspalast mit der Kapelle Aller Heiligen baute er großzügig um. Die Dächer ließ er mit vergoldeten Blechen decken, die das Fundament für die Wörterbindung „Goldenes Prag“ darstellten. Seit 1382 hörten böhmische Herrscher auf, die Prager Burg für mehr als 100 Jahre zu bewohnen. Der Königshof wurde an den Ort des heutigen Gemeindehauses umgezogen und zurück auf die Prager Burg kehrte er erst im Jahre 1483 unter Wladislaus aus der Jagiellonen-Dynastie.

Obwohl der Herrscher bereits 1490 nach Ofen (Buda) umsiedelte, ließ er die Prager Burg im spätgotischen Stil unter der Bauleitung von Benedikt Ried umbauen. Er war der Baumeister des großartigen Wladislaus-Saals, des größten weltlichen gewölbten Raums des damaligen Europas, mit dem die ersten Renaissancezeichen nach Prag kamen. Er führte großartige Bauregelungen einschließlich des Ausbaus eines neuen Mauerwerks, der Wehrtürme und der Erweiterung des Königspalastes durch. Zu seiner Zeit klang die Gotik aus und es setzte sich allmählich ein neuer Baustil durch, die Renaissance.

Der direkte Einfluss der italienischen Kunst des neuen Stils wurde in Prag unter der Regierung von Ferdinand I. (von Habsburg) und nach seinem Weggang von Prag unter der Wirkung des Statthalters Ferdinand von Tirol am meisten beobachtet. Damals wurde die mittelalterliche Burg in ein bequemes Renaissanceschloss mit Gärten umgewandelt. Im nördlichen Königsgarten entstand die typisch italienische Architektur des Königlichen Lustschlosses.

Zu einer großen Bauaktivität trug im Jahre 1541 ein Brand bei, der die Burgobjekte sowie die Umgebung ziemlich viel kaputt machte. Im Rahmen der Wiederherstellung wurden sowohl die Wohnräume als auch die Kirchenobjekte umgebaut. Unter der Regierung der ersten Habsburger kamen ins Burggelände auch Adelspaläste dazu (zum Beispiel der Pernstein-Palast - später Lobkowicz-Palast, Rosenberg-Palast und weitere). Im Nordwesten wurden Pferdestallgebäude erbaut.

Unter der Regierung des Kaisers Rudolph II. (1576 - 1611) erreichte der Renaissance- und Manierismusumbau der Burg, die zum zweiten Mal zum Zentrum des Reiches und insbesondere zum Zentrum der europäischen Kultur und Wissenschaft wurde, seinen Gipfel. Auf dem II. Vorhof wurden neue Räume für die Sammlungen Rudolphs erbaut - der Neue (heute Spanische) Saal und die Rudolph-Galerie. Es entstand auch der Verbindungstrakt zwischen dem Nordwest- und dem Südwestteil der Burg. Eben hier befanden sich die berühmte Kunstkammer und weitere Räume für die Sammeltätigkeit Rudolphs. Es wurden auch weitere Pferdestallobjekte für seine seltenen spanischen Pferde aufgebaut. Während der Rudolph-Zeiten wurde auch der Grundstein der berühmten Goldenen Gasse gelegt. Laboratorien der Rudolph-Alchymisten sollen im Pulverturm über dem Hirschgraben gewesen sein. Die Burg erlitt erneut erhebliche Schäden, als sie 1631 vom sächsischen Heer und 1648 von den Schweden besetzt und ausgeplündert wurde. Nach dem Dreißigjährigen Krieg kümmerten sich die Habsburger um den Prager königlichen Sitz nicht allzu sehr.

Erst Maria Theresia führte in den Jahren 1755 - 1775 einen umfangreichen Umbau der Prager Burg zu einem repräsentativen Schlosskomplex durch. Der Grund für die massive Bauaktion waren Kriegsschäden, verursacht durch die intensive Bombardierung der Burg bei Kriegskonflikten zu Beginn ihrer Regierung. Den Umbau entwarf der Wiener Architekt Nicolo Pacassi, der auch den I. Vorhof mit dem monumentalen Eingangstor projektierte. Aus der Zeit des theresianischen Umbaus stammt auch die Kapelle des Heiligen Kreuzes auf dem II. Burgvorhof und weitere Gebäude, insbesondere die Edeldamenanstalt. Dem Südflügel prägte er die einheitliche monumentale Spätbarockfassade eines Repräsentationssitzes ein. Seine durch das Wiener Rokoko und den französischen Klassizismus beeinflussten Pläne brachten die Baumeister Anselmo Lurago, Anton Kunz und Anton Haffenecker zustande.

Im 19. Jahrhundert verfiel die Burg, in mehreren Objekten ließ sich nach den josephinischen Reformen das Heer nieder. Zu Bauregelungen einiger Objekte kam es im Zusammenhang mit dem Aufenthalt von Ferdinand I. dem Guten auf der Burg nach seiner Abdikation im Jahre 1848 und weiter im Zusammenhang mit der Vorbereitung auf die vorgesehene Krönung von Franz Joseph I. in den 60er Jahren. Nach 1859, als die Gemeinde für die Fertigstellung der St. Veit Kathedrale entstand, begann zuerst die Reparatur und anschließend unter der Wirkung des Architekten Joseph Mocker wurde die Arbeit an der eigentlichen Fertigstellung der St. Veit Kathedrale aufgenommen, abgeschlossen im Jahre 1929.

In den Jahren 1920 - 35 führte ausgedehnte Regelungen der Prager Burg als des Sitzes des tschechoslowakischen Präsidenten der bedeutende slowenische Architekt Josip Plečnik durch, der den wertvollen historischen Raum mit modernen Zivilisationsansprüchen meisterlich zusammenfügte. Seine Regelungen betrafen vor allem den 1. und 3. Vorhof, die Südgärten der Burg, den 4. Vorhof mit dem Basteigarten sowie zahlreiche Innenräume. Er schuf z.B. die Säulenhalle, Privaträume der Präsidentenwohnung einschließlich des Arbeitszimmers Masaryks. Sein Schüler Otto Rothmayer brachte die unvollendeten Lösungen einiger Burginnenräume nach dem 2. Weltkrieg in vergleichbarer Qualität zu Ende.

Im Jahre 1936 ist Pavel Janák und nach ihm seit 1959 Jaroslav Fragner Burgarchitekt geworden.

Nach dem Wendejahr 1989 wurde die Prager Burg an vielen Stellen für die Öffentlichkeit geöffnet. Während der Amtszeit des Präsidenten Havel kam es auf der Burg zu Regelungen der Innenräume und zum Ausbau zweier neuer Eingänge in den 2. Vorhof nach dem Projekt des Bildners und Designers Bořek Šípek. Mit einem bedeutenden Preis wurde der Durchstich durch den Wall der Pulverbrücke im Hirschgraben belohnt (Arch. Josef Pleskot). Interessant ist auch das moderne Gewächshaus der weltberühmten Architektin Eva Jiřičná. Der Georg-Platz (Jiřské náměstí) wurde neu bepflastert und geregelt. In Zusammenarbeit mit den Fachleuten aus dem Getti-Institut wurde die Mosaik „des Letzten Gerichts“ renoviert. Im Jahre 1990 wurde die Prager Burg feierlich beleuchtet und dieser Zustand dauert von der Dämmerung bis zur Mitternacht bis heute. In der touristischen Hauptsaison dauert die Beleuchtungszeit sogar eine Stunde länger, bis 1 Uhr. Die Tradition der elektrischen Beleuchtung, jedoch im viel kleineren Umfang, begann im Jahre 1928, als die Lampen zum 10. Jubiläum der Republikentstehung installiert wurden. Ein wenig ähnelte die heutige feierliche Beleuchtung jener aus dem Ende der 60er Jahren, heute ist sie allerdings viel detaillierter und in den Kommunistenzeiten wurde sie nur bei feierlichen Gelegenheiten angemacht. Beleuchtungswürdige Tage waren damals Staatsfeiertage oder bedeutende Republiktage, denen allerdings aus der kommunistischen Sicht die Anerkennung nicht fehlte.

In den letzten Jahren entwickelte sich die Umbau- bzw. Renovierungstätigkeit in vielen Objekten der Burg und eine erhebliche Aufmerksamkeit wurde der archäologischen Untersuchung gewidmet, die bereits seit 1925 läuft und viele Erkenntnisse über die Burggeschichte brachte. Die Untersuchung sowie die Renovierung der einzelnen Räume und Objekte ist von der Idee motiviert, sie dadurch, dass sie der Öffentlichkeit zugänglich gemacht werden, möglichst viel zu beleben.

Nakhl castle restored, inland Oman.........

 

North and inland to dramatic Nakhl and its restored rock-top fortress above oasis palmery at the base of a mountain fissure. The fort/palace thus emerges/perches above a palm grove against the backdrop of the Hajar cliffs. Earth and rock mass construction; sturdy despite the fort's antiquity. It's now a historic place -- no charge to enter. Pre-Islamic origins. It underwent earlier restoration in the 9th and 16th Cs, as well as recently.

 

Five cylindrical towers adorn the fort which occupies 3,400 sq metres. Its walls follow the shapes of the rising and falling pleats of rock; a series of courtyards at split-levels, with labyrinthine staircases from terrace to terrace. Thick walls result in deep reveals; carved woodwork doors and screens; and modulation of glare and control of heat.

More than 60 historic forts have been restored in Oman in recent years.

Many of the older castles and monasteries of Oman date back to before Islam moved in and were built by the Persians for protection.

"Nakhl is located in the south of the Batinah, at the foot of Jebel al Akhdar in the Western Hajar Mountains. Upon entry to Nakhl, the most prominent feature is the fort, which is built on a 200m high craggy outcrop. The fort has been extended over the centuries and in 1990, was restored by Sultan Qaboos. There are a number of hot springs in Nakhl, one of which is situated close to the fort: Thuara spring is an important source of water to the residents of Nakhl, as it irrigates around 90% of the land."

Da’Marcus Baymon is a Dean’s Honored Graduate in the Section of Neurobiology, and will graduate with a bachelor of science in neurobiology from the School of Biological Sciences. He is being recognized for his scholastic achievement and leadership activities, as well as research that resulted in an undergraduate thesis performed under the direction of Professor John Mihic.

 

Da’Marcus transitioned to the Mihic laboratory after working with Dr. Josh Beckam in the Freshman Research Initiative. Research in the Mihic laboratory is focused on developing a better understanding of how ligand-gated ion channels function and how allosteric modulators act on these receptors, with a specific focus on molecular, biochemical and electrophysiological techniques to elucidate the processes underlying receptor activation and allosteric modulation. Da’Marcus studied a novel Drosophila cys-loop ligand-gated ion channel that activates spontaneously in the absence of any ligand. In order to do this, he had to learn how to isolate Xenopus oocytes, inject their nuclei with cDNAs, and then assay electrophysiological receptor function using a two-electrode voltage-clamp apparatus. He obtained useful data and will be a co-author on a manuscript that will be submitted on this topic.

 

Beyond the research lab, Da’Marcus has been active in the life of the College as a mentor to many younger students. Assistant Dean Susan Harkins and Assistant Director Cassandra Delgado-Reyes recruited him from the students in the Texas Interdisciplinary Plan to serve as a mentor to new students. He acted as an undergraduate teaching assistant in chemistry and later as an assistant coordinator in the Peer Leadership Academy, finally becoming the lead mentor for TIP. Da’Marcus was recognized as the 2012 Texas Parents’ Outstanding Student for his service, leadership, and academic excellence.

 

This fall, Da’Marcus will be attending the University of Texas Medical Branch at Galveston to obtain an MD, with hopes of also pursuing a PhD in neuroscience. He’s selected a collection of books for his summer reading, including Gifted Hands: The Ben Carson Story by Ben Carson, M.D.; From Neuron to Brain: A Cellular and Molecular Approach to the Function of the Nervous System by Nichols, Martin, Wallace, and Fuchs; and The House of God by Samuel Shem.

The Travel Agent lets you use road brake levers with mountain bike calipers, by effectively doubling the amount of cable pull. It's far cheaper than going to road calipers, and if I ever go back to flat bars, I can just keep using the same brakes.

 

Brake feel at the levers is basically every bit as good as it was before, with pretty smooth modulation. Same goes for feel at the 'cross levers.

Having owned the 2008 Kona Sutra for ten months, and just completed the first chain/cassette replacement, I thought it was about time for a long term review, to give other people an idea of what living with the Sutra has been like. My previous post explains why I chose the Sutra - I came up with what I thought was an impossibly eclectic list of requirements from a bicycle, and the Sutra ticked every single box.

  

Here's some specs, for the statophiles out there: Frame size C54cm Frame tubing Dedacciai COM 12.5 Butted Cromoly Fork Kona P2 700c TB Disc w/Lowrider Headset TH Crankarms FSA Gossamer MegaExo Chainrings 30/39/50 B/B FSA MegaExo Pedals Shimano PD-M520 SPD - Silver Chain Shimano HG53 --> Shimano HG93 XT Freewheel Shimano Deore (11-32, 9 Spd) --> Shimano XT M760 (11-32, 9spd) F/D Shimano Tiagra Triple R/D Shimano XT Shadow Shifters Shimano Bar-Con Handlebar FSA RD30 0S Stem FSA OS-190LX Grips Velo Wrap with Gel Brakes Avid BB7 Road Disc Brake Levers Shimano BLR-600 Front Hub Shimano M525 Disc Rear Hub Shimano M525 Disc Spokes DT Stainless 14g Tires Continental Contact 700 x 32C --> Schwalbe Marathon Plus 700x38c Rims Mavic A 317 Disc Saddle Selle Italia XO SE --> Brooks B17 Seatpost FSA SL-280 Seat Clamp Kona Clamp Rear Rack Tubus Logo Panniers Bikebins Computer Sigma DTS 1606 L Fenders SKS Chromoplastic

  

My primary (i.e. 99% of the time) use of the Sutra has been for commuting. I have covered over 2700 miles (4500km) in the time I have owned it. My commuting route through London is pretty tough on bikes - the roads south of the Thames are awful and full of potholes, through the City there is broken glass all over the place, and further north of the river there are speedbumps everywhere. When I first got the Sutra she was wearing Continental Contact tyres, and they were pretty poor for commuting. They punctured easily and transmitted the bumpiness of the road right up into my forearms. Not much fun. After one puncture too many I replaced the tyres with Schwalbe Marathon Pluses, in their largest diameter, and the difference was marked. The increased volume of air provides a lot more cushioning for the arms, and I have not had a single puncture yet, despite having pulled 6mm long pieces of glass out of the tyre surfaces. The tyres are relatively heavy, but then so is the rest of the bike, and extra weight makes you stronger!

  

The original rear rack was pretty flimsy, and it did not allow the attachment of the Bikebin panniers I bought to try and add some rigidity. I ended up having to angle grind chunks out of the rack to fit the panniers, which can't have improved their structural integrity. After a month of experiencing the odd sensation of the bike wagging its tail whenever I stood up to pedal hard, I bit the bullet and upgraded the rack to a Tubus Logo. It was a tight fit with the rear disc brake, but the difference was immense. Gone was the sensation of a jelly-like bike, to be replaced by a sensation of rigid stability. Whilst the rack was expensive, it made all the difference, and I would highly recommend it.

  

Speaking of the brakes, they have saved my life on more than one occasion, usually when a Taxi decides to perform an emergency stop to pick up a fare. The brakes stop consistently in all conditions, and so far I have not had to replace the pads, althoguh I think it will be time to do it soon. Not bad considering I have travelled almost five thousand kilometres in all weathers in the stop-start conditions of London. I was concerned that the brakes might be too powerful, but the modulation provided by the levers and the flex in the arm of the brake means that whilst the power is there if necessary, you have a lot of control over it. There is some disc drag, but this is owing more to my laziness than the brakes themselves, and seems to have little impact on cruising speeds.

  

Using the bike in all conditions has been excellent. The all-over fenders (something I have never fitted to a bike previously) really keep the rain off and eliminate spray from the road. I had to saw a bit of the front fender off to fit it over the larger tyres, and a little bit off the rear for the same reason, but after the modification they have been flawless.

  

I had heard reports of spokes snapping, and nothing happened to me until recently, when I noticed a detached spoke whilst replacing the rear cassette. I had no idea how long the spoke had been damaged for, and replaced it myself. The rear wheel is slightly askew, but it does not foul on anything, which is good considering the small tolerance between it and the fender. To be fair, I have been jumping off kerbs and sometimes it is impossible to miss a massive hole in the road when you are in busy traffic. An upgrade I am considering is a stronger rear wheel, although it is not pressingly urgent.

  

The ride of the bike is super smooth, and certainly not anything like the road bikes I am used to. I use my other road bike for triathlons, and whilst it is a lot more nimble, it is much less comfortable. The Sutra is comfortable all day long, owing in no small part to the Brooks B17 saddle, which took about two thousand miles to properly break in! It was worth it though - sitting on the bike is like sitting in an armchair (albeit a very odd armchair, but an armchair nonetheless). I tend to cruise at about 20mph on her, and my 10.5 mile commute to work takes about 37 minutes. I have started seeking out hills in preparation for some touring of Wales, and the sutra certainly loves to climb. The aggressive, mountain-bike-like frame geometry no doubt assists in this, and is confidence inspiring when climbing and descending. The bar-con shifters were a novelty for me, but they make a lot of sense, especially if replacement shifters were needed on a tour. There are even bosses on the downtube to fit truly old-school shifters in an emergency.

  

The weight of the bike was a shock initially - weighing in at 15kgs without the accessories, she weighs significantly more than my Specialized Hardrock mountain bike, which is saying something! Over time I have become accustomed to the weight, and now it feels normal. The main advantage of this is that when I ride anything else, it feels super light and goes very rapidly. This makes this bike an ideal training steed.

  

In conclusion, I have found a lot to love about the Kona Sutra - she's tough, strong and surprisingly fast. There were some niggles about fitting add-ons, but they were all easy to overcome, and the result has been a reliable bike that I think will keep delivering for years.

Coming soon, two new modules from Pittsburgh Modular. From Rick at Pittsburgh:

 

"Dual Index: ($139 available in September) An 8hp high quality dual linear VCA with both offset gain and attenuation plus a mix out and room for my big fingers. This module is based on the Generator's Index circuit. Nice warm sound.

 

VCBend: ($139 available in September) A 6hp control voltage modulation module. This module takes the bipolar control voltage input and bends it to the amount of the CV input in relation to the Internal Voltage Reference pot. This module favours esoteric applications over precision. More often than not the output voltage does not resemble the input in any way. The control voltage output of this module is always positive. Both the control voltage input and VC input are attenuverted."

I became curious whether I could reverse-engineer and recreate the IR signal that my ST-E2 wireless flash transmitter produces. So, I put a photosensor on my roommate's oscilliscope to see what I could find.

His scope isn't quite up to the job. It's an older analog scope, with no memory. So I ended up setting up my camera in front of it to try and record the trace. Here's the result. I tried a bunch of different settings, but there's still more experimenting to be done. Each successful capture takes about 5 tries, to get everything aligned right. The scope here is set to 0.5V/div (not zeroed vertically), and 1ms/div. The photosensor pulls low when it sees light.

Looks to me like pulse modulation, something like 64 bits, 10KHz. Of course, it has to be pulse modulation; the transmitter transmits by firing a little flashbulb. I think I might have enough here to recreate at least the signal for the pilot button. Tomorrow.
