Datum TymServe 2100 GPS Network Time Server with optional rubidium oscillator, locked to GPS. A Stratum 1 network time source.
Paid almost nothing for this mint condition rubidium time server on eBay, because seller thought it had a defective display... listing said it was "burned out". He was selling it for parts, claiming: "untested... powers up, display needs replacement". Cost $102.00.
When it arrived, display was set to minimum. Display contrast is easily adjusted by buttons 4 and 9 (lighter to darker). A few pushes and the display was back to normal. It is fortunate that no one reads manuals. Sold it on eBay for $695.00.
If you're buying one, avoid the Rb oscillator... for 99% of applications it is a waste of money. Datum TymServe 2100 network time server is obsolete, but if you can buy one in guaranteed working condition very inexpensively, it does the job.
subatomic Midibox SID V2
synthesizer in old vintage commodore c64 computer case
read about this DIY project here in the work blog: www.subatomicglue.com/sidl0g/
for information about making your own midibox go here: www.ucapps.de/midibox_sid.html
This is a MidiboxSID, a synthesizer that has sound chips from the original commodore 64 personal computer from the 1980's. These sound chips are called the SID 6582
The synth is built into an original Commodore 64 computer case. And features 8 SID chips (4 stereo pairs - one SID per ear x 4 voices). Each SID chip has 3 oscillators and a variety of other features like filters, ADSR, ringmod, sync. The synth has a very flexible (and simple to use) modulation matrix, LFO, bassline sequencers, and stores patches in presets.
UPDATE:
2008-05-28 We got midibox of the day! and also covered on the midibox.org's blog

Nel cerchio imperfetto del suo universo ottico la perfezione di quel moto oscillatorio formulava promesse che l’irripetibile unicità di ogni singola onda condannava a non essere mantenute. Non c’era verso di fermare quel continuo avvicendarsi di creazione e distruzione. I suoi occhi cercavano la verità descrivibile e regolamentata di un’immagine certa e completa: e finivano, invece, per correre dietro alla mobile indeterminazione di quell’andirivieni che qualsiasi sguardo scientifico cullava e derideva.
Alessandro Baricco, da “Oceano mare”
After a recent strobist shoot it quickly became obvious that my single SB800 wasn't going to be enough, and although I was able to borrow some more from a good friend, I really needed a more permanent solution.
Not having the money to blow on 3 more SB900/800 or 600 flashes (that's posh lens money that is!) I thought I'd see what I can do with a soldering iron. Unfortunately soldering irons only emit heat and not light so I turned to ebay.
5 days later I'm the proud owner of some classic strobes. Two Vivitar 283s, a Vivitar 285 and some great little micro controllers from a friendly Dutchman.
The 283s had 300volts at their hotshoe, so they weren't going anywhere near my D300! The 285 was only 7 volts, but it's all going off camera anyway.
I have the prototype hardware sorted, now I just have to program the microcontrollers
What you can see here is
Vivitar 283 - £16 from ebay
6v 7.2Ah SLA battery - £14 from Maplin
JeeNode(V4) - €17.50
2xOptotriac isolators - £1.50 each from maplin, far cheaper from Farnell (but still cheaper than getting 300v up the Jeenode!)
The Jeenode(V4) comes complete with an RFM12B radio module, meaning I have all the parts needed to make a remote trigger. The hotshoe even unscrews from the vivitar flashes, which means I've even got a useful donor part to use for the input to the transmitter.
Button board and breadboard are for test purposes only. Triple AA battery box will only be used on the camera trigger transmitter end, not the remote strobe end. The remote end will run from the 6V SLA
Due to the low internal resistance of the 6 volt sealed lead acid battery the 283 recharges from a full blast in under 3 seconds! Probably best not to do too many of these in quick succession or the oscillator circuit is bound to melt. I'd add "improve flash cooling" to the "to-do" list.
Bar the external battery connection wires the 283 is unmodified. Everything that is required appears on the connector behind the thyristor sensor. A bit of veroboard and some 0.1" spaced circuit board pins make a good plug.
For anyone that's interested the pins are
1.......2
....3
4.......5
(This is my numbering system looking at the front of the flash from the outside).
1 - Connects to the internal triggering system, this sits at 300volts
2 - Quench1
3 - The other half of the trigger. This connects to the outside of the hotshoe. Connect this to pin 1 and the flash will fire
4 - Connection to hotshoe centre. With the Thyristor unplugged the hotshoe is disabled. Connect this to pin 1 to reenable it. I left it disconnected, I don't want 300volts on the hotshoe centre pin!
5 - Quench2
Connecting Quench1 and Quench2 together stop the flash instantly.
Connecting different resistances between it varies the power.
I'm using the connect directly together method via the microcontroller to quench the flash after a preset time. The longer the time, the higher the flash power.
Oh, and for anyone interested, this picture was taken with the SB800 on hotshoe pointed straight up, camera was tilted at 45 degrees so the flash bounced off the white ceiling and the white tiles on the wall... The white surface it's all sitting on is the top of my chest freezer in the utility room!
Progress is made, and flashes flash... www.flickr.com/photos/steve_snaps/4566541603/
Longtime customer Herr Kringle came a knockin’ again this year with another epic custom build request. To address a new level of intercontinental delivery challenges this season, we sourced a clean J80 Land Cruiser and upgraded everything, starting with the powertrain.
Kringle Spec features a raucous 600 HP delivered to all four wheels through a twin-turbocharged 4.0L V8 coupled with a 16KW plug in hybrid dual motor setup configured to pwn even the biggest obstacles terra firma can conjure.
The package is completed by a Portable roof-mounted SatNav Unit working in tandem with our custom Compact Trans-Dimensional Oscillator, enabling Herr Kringle to deliver even the most difficult packages in little more than the space of a wink.
I hope you enjoy, and Happy Holidays!
What is the digital TV (DTV) transition?
The switch from analog to digital broadcast television is referred to as the digital TV (DTV) transition. In 1996, the U.S. Congress authorized the distribution of an additional broadcast channel to each broadcast TV station so that they could start a digital broadcast channel while simultaneously continuing their analog broadcast channel. Later, Congress has set June 12, 2009 as the final date that full-power television stations can broadcast in digital only. Your local broadcasters may make the transition before then, and some already have.
Why are we switching to DTV?
An important benefit of the switch to all-digital broadcasting is that it will free up parts of the valuable broadcast spectrum for public safety communications such as police, fire departments, and rescue squads. Also, some of the spectrum will be auctioned to companies that will be able to provide consumers with more advanced wireless services (such as wireless broadband).
Consumers also benefit because digital broadcasting allows stations to offer improved picture and sound quality, and digital is much more efficient than analog. For example, rather than being limited to providing one analog program, a broadcaster is able to offer a super sharp “high definition” (HD) digital program or multiple “standard definition” (SD) digital programs simultaneously through a process called “multicasting.” Multicasting allows broadcast stations to offer several channels of digital programming at the same time, using the same amount of spectrum required for one analog program. So, for example, while a station broadcasting in analog on channel 7 is only able to offer viewers one program, a station broadcasting in digital on channel 7 can offer viewers one digital program on channel 7-1, a second digital program on channel 7-2, a third digital program on channel 7-3, and so on. This means more programming choices for viewers. Further, DTV can provide interactive video and data services that are not possible with analog technology.

This is some sort of an intergalactic smart phone. Who lets us talk directly to our extra terrestrial creators. You type or speak your message into the device, and the guy on in the middle of the left part of the machine transcribe it. Then he send it to the amplifier, which is located in the bottom of the middle part of the machine. The amplifier sends the boosted signal up to the transmitter. The big wheel like thing in the center of the whole machine. The transmitter is based on Edward Leedskalnin's electro magnetic flywheel.
Ed is showing of his book "A book in every home" right above the transmitter.
The incomng signal comes in through the receiver, located the middle of the right part of the machine. It is in fact a miniature version of the Schaffer Vega diversity system made by Ken Schaffer, originally meant for electric guitars (used by guitarists like Angus Young, Tony Iommi, David Gilmour, Ace Frehley, Eddie Van Halen to name a few). It is aided by 16 Tesla coils mounted in a circle around the reciever.
Nikola Tesla himself is tweaking the knobs, making sure everything is in perfect sync.
The Tesla coils also provide the whole machine with power.
They collect excess electrisity from the air. We waste tons of electrisity out in the aether every second. The power is routed through a step up/down transformer mounted above the receiver and Tesla coils.
The Tesla coils usually pick up more electrisity than the unit needs, so much of it gets stored in the PMH magnet storage behind Edward Leedskalnin. If you don't know who Nikola Tesla and Edward Leedkalninare, you have some reading to do. Loose both yourself and your lead in the many stories of these long gone heroes.
The signal from outer space is fed through a crystal skull who serves as a step down transformer. The message must be simplified and deciphered. Or else we wouldnt be able to understand anything. Then the signal is routed straight to the guy you gave your first message to (if the signal is weak, it will go through the amplifier).
He transcribes the messages in to written words. If you for some reason is unable to read, the message will go through a speak synthesis. The spoken words will either be sent through the speaker (bottom left), or through the minijack output (top left). The translators instruments look suspiciously like the old EMS VCS-3 synthesizers. And one of the good old Moogs. The whole machine should fit in the palm of your hand. Depending on the size of your hand of course.
The whole drawing is inspired by a quote by Nikola Tesla. "If only the world knew the significance of 3-6-9". Or something like that. I do not remember exactly how he said it. But he believed that the numbers 3, 6 and 9 was the key to the universe. And I wouldn't be surprised if he was right. After all, he truly was an extraordinary gentleman.
This makes up the basic composition. In a quite crude way, as it is linked to simple graphic elements. 3 main parts, and 6 big wires (that connects the 3 main parts). And 3 + 6 is 9. There we have it. Not quite what Tesla had in mind, but more than enough to keep me busy for a few weeks.
The music and instruments of AC/DC and Jean Michel Jarre also had quite an influence on how this drawing turned out. Particularly Angus Young's old wireless unit. When the right and middle part of the drawing was constructed, I suddenly started banging my head into the wall and kept doing that for a while. Until my girlfriend gave me a ticket to a concert with Jarre as a birthday present. My head suddenly banged through the aforementioned wall. Seeing and hearing the old analog synthesizers made some ideas appear that finished the machine.
This is the drawing that I am most satisfied with to this date. It looks better in real life that on this grainy little .jpeg with reflections from both sunlight and a slightly psychedelic wallpaper (the drawing is sitting in a frame in this picture).
Sorry about the photographic quality. I will upload a better picture sometime later.
If anybody wants to know, the dimensions are: 90x204cm.

The Staccatone was invented by Hugo Gernsback and Clyde J. Fitch. Gernsback promoted it as a do-it-yourself project for amateur electronics enthusiasts. The instrument had a single vacuum tube oscillator controlled by a crude switch-based 16 note ‘keyboard’. The switch-based control gave the note a staccato tone.

A pendulum clock is a clock that uses a pendulum, a swinging weight, as its timekeeping element. The advantage of a pendulum for timekeeping is that it is a harmonic oscillator; it swings back and forth in a precise time interval dependent on its length, and resists swinging at other rates. From its invention in 1656 by Christiaan Huygens until the 1930s, the pendulum clock was the world's most precise timekeeper, accounting for its widespread use.
Throughout the 18th and 19th centuries pendulum clocks in homes, factories, offices and railroad stations served as primary time standards for scheduling daily life, work shifts, and public transportation, and their greater accuracy allowed the faster pace of life which was necessary for the Industrial Revolution.
Pendulum clocks must be stationary to operate; any motion or accelerations will affect the motion of the pendulum, causing inaccuracies, so other mechanisms must be used in portable timepieces. They are now kept mostly for their decorative and antique value. (Source: Wikipedia).

Phase 2: After a couple of years amassing a collection of speakers taken from stuff found in the trash, and countless hours of work, I finally got them off my floor and onto the wall.
There are 47 speakers per panel, but only 16 per panel are wired up to the control box. The box takes a 2 channel input and randomly selects which of the speakers the sound is directed to (for each panel). The rate can be controlled by the knob, or via an external CV. There is also the optional interruption control on a per-channel basis... this cuts the sound going to a panel according to the rate set via the knob (or external CV). Alas, the box and the speakers are not very clean-sounding, so not just any audio is suitable. It is best to feed it with simple drone oscillators.
No video could really demonstrate what this installation sounds like in person, with the sound moving around.
I created a page about this project here: www.jamesschidlowsky.ca/sweet32.html .

Lockheed C-141 model in the Transonic Dynamics Tunnel (TDT). By the late 1940s, with the advent of relatively thin, flexible aircraft wings, the need was recognized for testing dynamically and elastically scaled models of aircraft. In 1954, NASA's predecessor agency, the National Advisory Committee on Aeronautics (NACA), began converting the Langley 19-foot Pressure Tunnel for dynamic testing of aircraft structures. The old circular test section was reduced to 16 x 16 feet, and slotted walls were added for transonic operation. The TDT was provided with special oscillator vanes upstream of the test section to create controlled gusty air to simulate aircraft response to gusts. A model support system was devised that freed the model to pitch and plunge as the wings started oscillating in response to the fluctuating airstream. The TDT was completed in 1959. It was the world's first aeroelastic testing tunnel.

Most buffer circuits for JFET oscillators seem to throw out the advantages, introduce noise and distortion. This one is good to about 150MHz by scaling the 68 pF capacitors. You’ll get a hefty output power. Note that the distortion cancellation from the diode is supply voltage/amplitude sensitive so adust supply for lowest 2f

nrhp # 87001463- The Highland Light (previously known as Cape Cod Light) is an active lighthouse on the Cape Cod National Seashore in North Truro, Massachusetts. The current tower was erected in 1857, replacing two earlier towers that had been built in 1797 and 1831. It is the oldest and tallest lighthouse on Cape Cod.[5]
The grounds are open year-round, while the light is open to the public from May until late October, with guided tours available. Highland Light is owned by the National Park Service, and was cared for by the Highland Museum and Lighthouse, Inc. until 2014 when Eastern National, another non-profit group, took over the contract to operate the facility as a tourist attraction.[6] The United States Coast Guard operates the light as an aid to navigation.[7] The United States Navy ship USS Highland Light (IX-48) was named after the light. It is listed on the National Register of Historic Places as Highland Light Station.
In 1797, a station authorized by George Washington was established at this point on the Cape, with a wood lighthouse to warn ships about the dangerous coastline between Cape Ann and Nantucket. It was the first light on Cape Cod. In 1833, the wood structure was replaced by a brick tower and in 1840 a new lantern and lighting apparatus was installed. In 1857 the lighthouse was declared dangerous and demolished, and for a total cost of $17,000, the current 66-foot brick tower was constructed.[8]
On June 6, 1900, the light was changed from a fixed beam to flashing, with a new. The new Barbier, Benard & Turenne first-order Fresnel lens had four panels of 0.92 meter focal distance, revolved in mercury, and gave, every five seconds, flashes of about 192,000 candlepower nearly one-half second in duration. While the new lens was being installed, the light from a third-order lens was exhibited atop a temporary tower erected near the lighthouse; it was later sold at auction. The Highland Light was then the most powerful on the east coast of the United States. Two four-horsepower oil engines with compressors operated by an engine fueled by kerosene, were added to ensure that the fog signal could be activated within ten minutes instead of the previous 45. A new fog signal was installed in 1929, an electrically operated air oscillator, to make it audible over a greater distance.[6]
The lighthouse was converted to electric operation in 1932 with a 1000-watt beacon. In 1946, Highland Light's Fresnel lens was replaced by modern aerobeacons, first by a Crouse-Hinds DCB-36 double rotating light and then by a Carlisle & Finch DCB-224, with a second unit as backup. Unfortunately, the Fresnel lens was severely damaged when it was removed, but fragments are on display in the museum on site. The light was fully automated by 1986 with a Crouse-Hinds DCB-224 rotating beacon.[9][6] In 1998, a VRB-25 optical system was installed.[3][6] Most recently, the light source is a Vega Marine LED beacon model 44/2.5 installed in April 2017.[10]
The current location of the lighthouse is not the original site. It was in danger of falling down the cliff due to beach erosion, so the structure was moved 450 feet (140 m) to the west. The government funding to do so was supplemented by money raised through fund raising by the Truro Historical Society.[11] The move was accomplished by International Chimney Corp. of Buffalo, New York and Expert House Movers of Maryland over a period of 18 days in July, 1996.[3][6] The move left the light station on Cape Cod National Seashore property, bordering the Highland Golf Course. After an errant golf ball broke a window, they were replaced with unbreakable material. In 1998, the keeper's house was modified to be a gift shop and museum. The lighthouse grounds are open year-round on Highland Light Road in Truro, with tours and the museum available from a National Park Service partner, Eastern National,[12] during the summer months.

“Sala de Máquinas” (Engine Room) is an audiovisual interactive installation, which intends to reflect on the idea of the reutilization of what we have acknowledged as obsolete...in this case old modified TVs that react to sound!
An electronic oscillator is connected to an open circuit, in a way that when the user touches 2 metal bars he/she himself/herself becomes the electrical resistance therefore being able to vary the frequency of sound.
The old modified TVs react to this sound as an oscilloscope having all kinds of different patterns and reactions.

"Magic Wire" is so called because of detecting proximity to antenna.
THE MAGIC WIRE
As shown in the diagram, the input tube is a type 6R7 duo-diode triode. The triode section forms the oscillator, in conjunction with the coil L1 which is center-tapped to the cathode. When the triode section is oscillating, the r.f. voltage developed from cathode to ground is impressed on the diode section, causing current to flow through R2 and making the diode plates negative with respect to ground. The control grid of the 25L6 power tube is connected to the diode plates of the 6R7 and consequently a negative bias is placed on the grid which reduces its plate current to a very low value. As soon as the triode ceases to oscillate, there is no longer any r.f. voltage applied to the diodes, the voltage drops and the 25L6 draws high plate current, causing the relay to operate.
It will be noted that no rectifier tube or filler circuit is required in this design, yet the instrument functions on either a.c. or d.c. On a.c., the 6R7 oscillations and the 25L6 draws plate current only on the positive half-cycles. This principle effects a considerable saving in construction cost and in the size of the instrument.
After the parts required have been obtained, the first step in building the unit is to make the chassis, which consists simply of a piece of 16-gauge aluminum or steel bent and drilled in accordance with the plan shown. The front panel, which is included with the standard 6 by 6 cabinet, is drilled and a hole and grommet are placed in the rear panel. The oscillator coil is made by winding 100 turns of No.28 d.c.c. wire on a one-inch bakelite tube 3-1/4 inches long. A tap is brought out at the center of the winding. When the winding has been completed, the entire coil is dipped in a hot half-and-half mixture of beeswax and paraffin to keep the winding in place and exclude moisture. The sensitivity of the outfit is largely dependent upon the efficiency of the coil, so it should be carefully made. C1 is mounted on a small piece of 1/8-inch bakelite, because it must be insulated from the panel.
Wire the chassis first, starting with the heater circuits. Do not connect in the power cord until all wiring has been completed. The shield of the 25L6 is connected to its cathode, the shield of the 6E7 to the heater terminal which goes directly to the line. When all the main wiring has been completed, bring the power cord through the rear panel hole, and solder the three terminals to the terminal strip. The antenna wire is brought in through a rubber-grommeted hole in the top of the cabinet and connected to the stator or plate terminal of C1. A knot in the wire will relieve any strain on this connection. Stranded wire is preferred for the antenna.
The capacitances of C1 and C2 are largely dependent upon the length of antenna wire desired. If only 4 or 5 feet are required, C2 may be omitted. On the other hand, if the wire exceeds 15 feet, C2 will have to be larger than the value given. If the capacitance of C1 were made large (say 150 mmf. or more), C2 could of course be omitted but then the adjustment would become too critical.
The relay employed is a 3,000-ohm plug-in type of standard manufacture. It is a double-pole model and will handle a non-inductive load of 100 watts. It is somewhat more sensitive than is required and any other good relay of 1,000 ohms or more resistance should be suitable. The capacitor, C4, is shunted across the relay coil to prevent chattering. It may be advisable, in some cases, to put a 0.1 mf. paper capacitor across the relay contacts to stop sparking on heavy loads. It is better practice, however, to use a separate power relay when operating any but light loads.
In operation, the antenna wire is strung out well away from grounded metal objects and a 110-volt lamp is plugged into the outlet on the panel. When the tubes have heated, the lamp should light when the antenna wire is touched. If it lights without touching the wire, C2 should be screwed down until the lamp goes out. These adjustments should be made with C1 about one-half mashed. The panel may then screwed in on the cabinet and final adjustment made. This is done by gradually adjusting the vernier knob of the dial until the light remains lit when adjusting but goes out when the hand is removed from the dial. This may be carried to a point where the light will flash as soon as one approaches within 3 feet of the wire or instrument. It is better not to aim for such sensitivity, though, since it will vary somewhat with line voltage. A good, practical and stable point is about six to fifteen minutes or so for the instrument to acquire a stable point of operation owing to its sensitivity.

Tonight i ditched the glitchcore in favour of the Science Fair Electronic Project Lab for sound generation. There are many circuit set-ups allowing for the generation of all sorts of wonderful sounds including....the 'electronic cat', the 'light controlled electronic harp' a white noise generator, and oh..... a pulse oscillator tone generator.....
I then used these sounds in VVVV for realtime analysis to drive some visuals i made for a VJ set sometime ago.

"Studiava l'esatto punto in cui l'onda, dopo essersi rotta una decina di metri più indietro, si allungava divenuta lago, e specchio e macchia d'olio risalendo la delicata china della spiaggia e finalmente si arrestava l'estremo bordo orlato da un delicato perlage per esitare un attimo e alfine, sconfitta, tentare una elegante ritirata lasciandosi scivolare indietro, lungo la via di un ritorno apparentemente facile ma, in realtà, preda destinata alla spugnosa avidità di quella sabbia che, fin lì imbelle, improvvisamente si svegliava e, la breve corsa dell'acqua in rotta, nel nulla svaporava. Bartleboom guardava. Nel cerchio imperfetto del suo universo ottico la perfezione di quel moto oscillatorio formulava promesse che l'irripetibile unicità di ogni singola onda condannava a non esser mantenute. Non c'era verso di fermare quel continuo avvicendarsi di creazione e distruzione.

Ő itt egy több mint 30 éves Accutron óra, elektromos, hangvillás szerkezet. A kép illusztrációnak készült egy cikkhez az Óra Magazinban.
"Max Hetzel találta fel a hangvillával működő órát. A hangvilla rezgésszáma szigorúan meghatározott és állandó. Az Accutron órában egy 20 mm hosszú hangvilla másodperenként 360 rezgést végez, amit egy hozzácsatlakozó kilincsmű visz a fogaskerék rendszerre és a mutatókra. Pontossága és egyszerűsége miatt verhetetlennek tartották. Az első amerikai mesterséges holdak vezérlőkészülékét Accutron óra szabályozta. Karrierjének a kvarcóra vetett véget." forrás: wikipedia
This here, is a 30 years old Accutron wrist watch, driven with an electromagnetically oscillated tuning fork.
"Bulova's Accutron watches, first sold in October 1960, use a 360 hertz tuning fork to drive a mechanical gear train to turn the hands. The inventor, Max Hetzel, was born in Basel, Switzerland, and joined the Bulova Watch Company of Bienne, Switzerland, in 1948. The tuning fork was powered by a one-transistor electronic oscillator circuit, so the Accutron qualifies as the first electronic watch" from wikipedia

This Philips QB 3.5/750 Tetrode vacuum tube is designed for use as a High Frequency amplifier and oscillator. It has an output of around 750 watts!
I received it as a gift some years ago and it's been sitting in a box in want of a new home. Since I'm not going to put it into service, I thought I would make up an acrylic display housing for it, so now it sits in my lounge room where I can enjoy it!
This is a big tube - Really big! The tube is 145mm high x 87mm wide.
Want to see what this tube looks like running? Check out this!

I found a data sheet on line with a sketch of the base, so was able to transpose this into CorelDRAW. I lasercut the box with enough clearance for the tube to 'float' in the middle. The Philips logo is engraved into the inside-surface of the sides.
