Manufactured in the 1960s by the Traid Corporation of Encino, California. This is a late model Fotron with âPictures Remainingâ slot on top. Vacuum cleaners, World BookÂźâą Encyclopedias, Fuller brushes and the Fotronâwhat do they have in common? They were all sold door-to-door. The Fotronâs price was a bit steep, ranging from $150 to $300. The cameras were made to take 10 exposures 1x1 inch on special cartidges containing 828 film. They featured many high-class advancements such as built-in electronic flash with rechargeable batteries (which is why the plastic camera is (a) large and (b) heavy!), electric film advance and pushbutton settings for exposure. At the time, these were expensive features. Still, the Fotron camera campaign is considered by some to be the greatest photographic ârip-offâ of the 20th century.
A personal note: This camera came to my collection by way of the George Eastman House collection. They occasionally sell âextrasâ from their collection to raise fundsâwatch for them on eBay. Visit their website at: www.eastmanhouse.org

With the booming popularity of nostalgic-styled motorcycles, Kawasaki drew from the vaults of history to create the W650. This addition to Kawasaki's line-up is reminiscent of the styling and technological design features of the Kawasaki W1 and W1SA parallel twin-cylinder motorcycles of the late '60s and early '70s. Swing a leg over it and experience some Good Times.
Improved comfort and handling for this classic remake.
Kawasaki drew from the vaults of its own history when it created the W650. Reminiscent of the styling and technological design features of the Kawasaki W1 and W1SA parallel twin-cylinder motorcycles of the late â60s and early â70s, the W650 piqued the interest of enthusiasts everywhere.
It only gets better in 2001. A new seat and redesigned tank pads enhance rider comfort, while revised steering geometry and front suspension changes improve handling.
The W650âs twin cylinder, air-cooled 676cc engine churns out plenty of responsive low- and mid-range power, due in part to its long-stroke 360 degree crankshaft that has both pistons rising and falling together. A modern four-valve cylinder head helps give the W650 a healthy top-end, too. The valves are actuated by a single overhead camshaft that is driven by a hypoid gear, where the bevel shaft is offset to one side of the gears for less noise and friction, and increased durability.
The pair of constant velocity carburetors are equipped with the Kawasaki Throttle Responsive Ignition Control (K-TRIC) throttle position sensor. Connected to the Digital Ignition system, K-TRIC varies ignition timing according to throttle position and engine rpm so that the ignition compensates for differing engine loads for crisp throttle response and better fuel efficiency.
Other modern engine features include a lightweight and compact rare-earth magnet generator rotor, wet sump, balancer shaft to help eliminate vibration, pushbutton electric starting and a slick-shifting five-speed transmission with Kawasakiâs Positive Neutral Finder that makes shifting into neutral when stopped a breeze. The W650 also runs much cleaner than the machines that inspired its design due to the Kawasaki Clean Air (KCA) system. Fresh air is fed into the exhaust just beyond the exhaust valves for reduced emissions.
The W650âs chassis design is clean and simple. A traditional double-cradle frame uses a hefty square-section backbone for rigidity. A half-degree increase in the steering angle plus a 2mm larger axle and new front hub featuring larger bearings improve handling. A steel swingarm and twin shocks with adjustable preload provide the rear suspension, while the ride up front has been improved with new fork springs and revised rebound and compression damping. Braking power is supplied by a 300mm front disc and rear drum.
This machine is finished off in classic Kawasaki W-model styling. A shapely gas tank features high quality paint and chrome with redesigned rubber knee pads that are thinner, lighter and have smoother edges. The shape of the long seat was slightly altered and padded ribs added to make it more comfortable. It still has plenty of room for both rider and passenger, plus itâs finished with a retro-looking white bead. A wide, chromed handlebar helps put the rider in an upright, natural position. Modern instrumentation that is re-angled toward the rider for better visibility includes a liquid crystal display for the odometer and trip meter.
The Kawasaki W650 recalls the great machines that helped to lay the foundation of Kawasaki performance. While its styling is a trip into the past, its modern features have the W650 pointed directly into the future.

The Graflex Graphic 35's history is a long story: it began as the Cee-ay 35, introduced by Perfex in 1949. Perfex immediately collapsed, and the CA was picked up by Ciro, which relaunched it as the Ciro-35. Ciro was in turn taken over by Graflex 2 years later. Rather than just giving it another quickie facelift, Graflex kept it on the market for a few more years as the Ciro 35 while working on this handsome redesign which preserved the original tools for the main chassis casting. The camera is better to look at than it is to use, the ergonomics (like many other US cameras) are a bit odd.... I am not fond of either the "see-saw" pushbutton focusing method or the odd, front-mounted shutter release (classic examples of the triumph of Styling & Clever Gadgetry over Function & Human Factors in the Industrial Design profession). The German lens and shutter are good though.
The Nash Rambler was introduced on April 13, 1950; in the middle of the model year. The new Rambler was available only as an upmarket two-door convertible â designated the "Landau". Without the weight of a roof, and with a low wind resistance body design for the time, the inline 6-cylinder engine could deliver solid performance and deliver fuel economy up to 30 mpgâUS (7.8 L/100 km; 36 mpgâimp).
Several factors were incorporated into the compact Nash Rambler's marketing mix that included making the most from the limited steel supplies during the Korean War, as well as the automaker selecting a strategy for profit maximization from the new Rambler line. The new Nash Rambler came only in a convertible body, a style that had a higher price in the marketplace and incorporating more standard features that make the open top models suitable more for leisure-type use than ordinary transportation.
The Nash Rambler was well equipped compared to the competition and included numerous items as standard equipment such as whitewall tires, full wheel covers, electric clock, and even a pushbutton AM radio that were available at extra cost on all other cars at that time.
In 1951, the Nash Rambler line was enlarged to include a two-door station wagon.

This is a project Iâve been gradually modifying since spring 2014: a full-size replica of Han Soloâs iconic weapon, rigged up with a small microcontroller programmed by Arduino to play sound effects and to make the muzzle flash blink! Making this project was rather difficult to the say the least, and I frequently ran into errors with the LEGO mechanics, the Arduino programming, the sound box, and the battery power â but nonetheless, Iâve succeeded in making custom toy function. Pulling the trigger makes the gunâs hammer and firing pin (with rubber bands) strike a momentary pushbutton, which is wired to the circuit board to pulse the microcontrollerâs sequence of blinking an LED and playing a PCM sound clip of Han Soloâs gun firing. The individual sound effect was extracted by me directly from the scene in Episode IV when Han correctly shoots Greedo first!

The Volkswagen Type 14A (commonly known as the HebmĂŒller Cabriolet or simply Heb) is a German car produced after the Second World War.
At the request of Volkswagen managing director Heinz Nordhoff, HebmĂŒller and Karmann would build cabriolets for Volkswagen, with as many Type 1 parts, such as chassis, engines, and body panels, as possible. HebmĂŒller was to build the 2+2 cabriolet, and Karmann the four-seat cabriolet. By contrast with the Karmann, the Heb was intended as a sporting model.
HebmĂŒller started production in June 1949, mechanically the Type 14A was the same as the Beetle saloon with mechanical brakes, and the Type 1's' 19-kilowatt (26 PS; 25 bhp) petrol engine. It also shared the Type 1's crank starting, and the cabriolet's icowl-mounted semaphore turn signals and its pushbutton Telefunken radio. The Heb differed in having the decklid and trunk lid being of a similar size and shape.
Retailing for 7.500 Deutsch Marks, the HebmĂŒller Cabriolet was available in a variety of colours, options were black, red and white in single tone, in two-tone combinations black and red, black and ivory, black and yellow and red and ivory was available, for extra charge buyers could choose their own combination.
A fire broke out on 23 July 1949 in the factory's paint department, and made its way to the production line. After the fire, HebmĂŒller did manage to produce later, but later became financially ruined in the early 1950s.
Production ended in 1953 with a total of 696 units produced, including 3 prototypes and 1 pre-production model. Around 100 are thought to survive.
Today a replica of the Type 14A is produced by the Brazilian convertible company Trocar.

1961 Chrysler Newport Station Wagon.
From the display: "Walter P. Chrysler founded the company bearing his name in 1925 from what had previously been the Maxwell Motor Company. He had earlier experience at Buick and Willys-Overland. Chrysler added the Plymouth, DeSoto, and Dodge nameplates to his corporation over time.
By the 1950's, Chrysler had gained a reputation for engineering excellence but rather boring styling. The image of Chrysler cars began to change with the increasing influence of stylist Virgil Exner, who came to the company in 1949 from Studebaker.
By the late '50s, Exner was bringing ever sleeker, wider, and stylish cars to market. The 1961 and '62 Chryslers were noted for their canted, quad headlights that gave the cars a unique appearance.
This massive station wagon is a great example of the large, powerful family cars of the early '60s. With its unique torsion bar front suspension, superb TorqueFlight automatic transmission (controlled by dash-mounted pushbuttons), and enough space for a family and all their "stuff", it was a great car for vacations and hauling all the things a suburban family needed.
In May 1961, Jurgen Vind, a Truckee construction company owner, bought the car in San Francisco. The car remained in the Vind family for the next 37 years, serving for daily commutes, family vacations, and as a first car for their daughter. The car survived near demolition in a terrible mudslide near Lake Tahoe in 1967. Placed in storage in the 1980s, the Vind family finally sold the car to Tom Ortiz in the '90s and restoration was begun. Tom still owns the car and keeps it here for us to enjoy."
Camera service tool.
Unknown for which camera and the exact function.
Probably for a Rollei camera.
A springloaded pushbutton with a circular surface mirror on its other side would perhaps indicate that this tool was used for lens collimation.

The telephone, or phone was developed in 1876 by Alexander Graham Bell. and improved by many other inventors. Telephones rapidly became common in advanced societies.
The essential elements of a telephone are a microphone (transmitter) to speak into and an earphone (receiver) which reproduces the voice in a distant location. In addition, most telephones contain a ringer which produces a sound to announce an incoming telephone call, and a dial or keypad used to enter a telephone number when initiating a call to another telephone. Until approximately the 1970s most telephones used a rotary dial, which was superseded by the modern DTMF push-button dial, first introduced to the public by AT&T in 1963. The receiver and transmitter are usually built into a handset which is held up to the ear and mouth during conversation. The dial may be located either on the handset, or on a base unit to which the handset is connected. The transmitter converts the sound waves to electrical signals which are sent through the telephone network to the receiving phone. The receiving telephone converts the signals into audible sound in the receiver, or sometimes a loudspeaker. Telephones permit duplex communication, meaning they allow the people on both ends to talk simultaneously.
The first telephones were directly connected to each other from one customer's office or residence to another customer's location. Being impractical beyond just a few customers, these systems were quickly replaced by manually operated centrally located switchboards. This gave rise to landline telephone service in which each telephone is connected by a pair of dedicated wires to a local central office switching system, which developed into fully automated systems starting in the early 1900s. For greater mobility, various radio systems were developed for transmission between mobile customer stations on ships and automobiles from the 1930s by the mid-1900s. The first hand-held mobile phone was introduced for personal service starting in 1973 by Motorola. By the late 1970s several mobile telephone networks operated around the world. In 1983, the Advanced Mobile Phone System (AMPS) was launched in the U.S. and in other countries soon after, and offered a standardized technology providing portability for users within a region far beyond the personal residence or office location. These analog cellular system evolved into digital networks with better security, greater capacity, better regional coverage, and lower cost. The public switched telephone network, with its hierarchical system of many switching centers, interconnects telephones around the world for communication with each other. With the standardized international numbering system, E.164, each telephone line has an identifying telephone number, that may be called from any authorized telephone on the network.
Although originally designed for simple voice communications, convergence has enabled most modern cell phones to have many additional capabilities. They may be able to record spoken messages, send and receive text messages, take and display photographs or video, play music or games, surf the Internet, do road navigation or immerse the user in virtual reality. Since 1999, the trend for mobile phones is smartphones that integrate all mobile communication and computing needs.
BASIC PRINCIPLES
A traditional landline telephone system, also known as plain old telephone service (POTS), commonly carries both control and audio signals on the same twisted pair (C in diagram) of insulated wires, the telephone line. The control and signaling equipment consists of three components, the ringer, the hookswitch, and a dial. The ringer, or beeper, light or other device (A7), alerts the user to incoming calls. The hookswitch signals to the central office that the user has picked up the handset to either answer a call or initiate a call. A dial, if present, is used by the subscriber to transmit a telephone number to the central office when initiating a call. Until the 1960s dials used almost exclusively the rotary technology, which was replaced by dual-tone multi-frequency signaling (DTMF) with pushbutton telephones (A4).
A major expense of wire-line telephone service is the outside wire plant. Telephones transmit both the incoming and outgoing speech signals on a single pair of wires. A twisted pair line rejects electromagnetic interference (EMI) and crosstalk better than a single wire or an untwisted pair. The strong outgoing speech signal from the microphone (transmitter) does not overpower the weaker incoming speaker (receiver) signal with sidetone because a hybrid coil (A3) and other components compensate the imbalance. The junction box (B) arrests lightning (B2) and adjusts the line's resistance (B1) to maximize the signal power for the line length. Telephones have similar adjustments for inside line lengths (A8). The line voltages are negative compared to earth, to reduce galvanic corrosion. Negative voltage attracts positive metal ions toward the wires.
DETAILS OF OPERATION
The landline telephone contains a switchhook (A4) and an alerting device, usually a ringer (A7), that remains connected to the phone line whenever the phone is "on hook" (i.e. the switch (A4) is open), and other components which are connected when the phone is "off hook". The off-hook components include a transmitter (microphone, A2), a receiver (speaker, A1), and other circuits for dialing, filtering (A3), and amplification.
A calling party wishing to speak to another party will pick up the telephone's handset, thereby operating a lever which closes the switchhook (A4), which powers the telephone by connecting the transmitter (microphone), receiver (speaker), and related audio components to the line. The off-hook circuitry has a low resistance (less than 300 ohms) which causes a direct current (DC), which comes down the line (C) from the telephone exchange. The exchange detects this current, attaches a digit receiver circuit to the line, and sends a dial tone to indicate readiness. On a modern push-button telephone, the caller then presses the number keys to send the telephone number of the called party. The keys control a tone generator circuit (not shown) that makes DTMF tones that the exchange receives. A rotary-dial telephone uses pulse dialing, sending electrical pulses, that the exchange can count to get the telephone number (as of 2010 many exchanges were still equipped to handle pulse dialing). If the called party's line is available, the exchange sends an intermittent ringing signal (about 75 volts alternating current (AC) in North America and UK and 60 volts in Germany) to alert the called party to an incoming call. If the called party's line is in use, the exchange returns a busy signal to the calling party. However, if the called party's line is in use but has call waiting installed, the exchange sends an intermittent audible tone to the called party to indicate an incoming call.
The ringer of a telephone (A7) is connected to the line through a capacitor (A6), which blocks direct current but passes the alternating current of the ringing signal. The telephone draws no current when it is on hook, while a DC voltage is continually applied to the line. Exchange circuitry (D2) can send an AC current down the line to activate the ringer and announce an incoming call. When there is no automatic exchange, telephones have hand-cranked magnetos to generate a ringing voltage back to the exchange or any other telephone on the same line. When a landline telephone is inactive (on hook), the circuitry at the telephone exchange detects the absence of direct current to indicate that the line is not in use. When a party initiates a call to this line, the exchange sends the ringing signal. When the called party picks up the handset, they actuate a double-circuit switchhook (not shown) which may simultaneously disconnects the alerting device and connects the audio circuitry to the line. This, in turn, draws direct current through the line, confirming that the called phone is now active. The exchange circuitry turns off the ring signal, and both telephones are now active and connected through the exchange. The parties may now converse as long as both phones remain off hook. When a party hangs up, placing the handset back on the cradle or hook, direct current ceases in that line, signaling the exchange to disconnect the call.
Calls to parties beyond the local exchange are carried over trunk lines which establish connections between exchanges. In modern telephone networks, fiber-optic cable and digital technology are often employed in such connections. Satellite technology may be used for communication over very long distances.
In most landline telephones, the transmitter and receiver (microphone and speaker) are located in the handset, although in a speakerphone these components may be located in the base or in a separate enclosure. Powered by the line, the microphone (A2) produces a modulated electric current which varies its frequency and amplitude in response to the sound waves arriving at its diaphragm. The resulting current is transmitted along the telephone line to the local exchange then on to the other phone (via the local exchange or via a larger network), where it passes through the coil of the receiver (A3). The varying current in the coil produces a corresponding movement of the receiver's diaphragm, reproducing the original sound waves present at the transmitter.
Along with the microphone and speaker, additional circuitry is incorporated to prevent the incoming speaker signal and the outgoing microphone signal from interfering with each other. This is accomplished through a hybrid coil (A3). The incoming audio signal passes through a resistor (A8) and the primary winding of the coil (A3) which passes it to the speaker (A1). Since the current path A8 â A3 has a far lower impedance than the microphone (A2), virtually all of the incoming signal passes through it and bypasses the microphone.
At the same time the DC voltage across the line causes a DC current which is split between the resistor-coil (A8-A3) branch and the microphone-coil (A2-A3) branch. The DC current through the resistor-coil branch has no effect on the incoming audio signal. But the DC current passing through the microphone is turned into AC current (in response to voice sounds) which then passes through only the upper branch of the coil's (A3) primary winding, which has far fewer turns than the lower primary winding. This causes a small portion of the microphone output to be fed back to the speaker, while the rest of the AC current goes out through the phone line.
A lineman's handset is a telephone designed for testing the telephone network, and may be attached directly to aerial lines and other infrastructure components.
HISTORY
Before the development of the electric telephone, the term "telephone" was applied to other inventions, and not all early researchers of the electrical device called it "telephone". A communication device for sailing vessels The Telephone was the invention of a captain John Taylor in 1844. This instrument used four air horns to communicate with vessels in foggy weather. Later, c. 1860, Johann Philipp Reis used the term in reference to his Reis telephone, his device appears to be the first such device based on conversion of sound into electrical impulses, the term telephone was adopted into the vocabulary of many languages. It is derived from the Greek: ÏáżÎ»Î”, tÄle, "far" and ÏÏÎœÎź, phĆnÄ, "voice", together meaning "distant voice".
Credit for the invention of the electric telephone is frequently disputed. As with other influential inventions such as radio, television, the light bulb, and the computer, several inventors pioneered experimental work on voice transmission over a wire and improved on each other's ideas. New controversies over the issue still arise from time to time. Charles Bourseul, Antonio Meucci, Johann Philipp Reis, Alexander Graham Bell, and Elisha Gray, amongst others, have all been credited with the invention of the telephone.
Alexander Graham Bell was the first to be awarded a patent for the electric telephone by the United States Patent and Trademark Office (USPTO) in March 1876. The Bell patents were forensically victorious and commercially decisive. That first patent by Bell was the master patent of the telephone, from which other patents for electric telephone devices and features flowed.
In 1876, shortly after the telephone was invented, Hungarian engineer Tivadar PuskĂĄs invented the telephone switch, which allowed for the formation of telephone exchanges, and eventually networks.

1941 Ford
The Ford car was thoroughly updated in 1941, in preparation for a time of unpredictability surrounding World War II. The 1941 design would continue in an aborted 1942 model year and would be restarted in 1946 and produced until the more modern 1949 Fords were ready. During the initial year of this car, it evolved considerably. The front fenders came in three pieces, the theory being that small damage could be replaced easily. During the year, it evolved into two pieces with the lower front and back sections being joined. The hood risers changed, the early ones being the same as 1940 Fords, changing during the year to the better later version. The 1941 Convertible had no rear side windows, the only side windows being in the doors; in 1942, quarter windows were added so the rear occupants could see out. Five different coil/distributor arrangements were used during 1941, causing confusion for mechanics. Other variations were: two different positions for the generator, and three for the cooling fan â front of the crankshaft, front of the generator (rare) and on a bracket. This is thought to be the first Ford to offer an oil filter. The two interior heaters were a "Southwind" gasoline burner, which had the advantage of keeping one warm in winter at drive-in movies (provided a small electric fuel pump was used), and a more ordinary hot-water type. Both had window defrosters. It had an excellent radio, which could consume the battery in about two hours. Electric windshield wipers were available in addition to the vacuum-powered wipers. Three different convertible power top mechanisms (vacuum, electric screw, and hydraulic) and two different header bar latching systems were used. Rear suspensions sometimes had a sway bar, most did not. It had excellent brakes for the time, and the best handling of an ordinary car at the time. It was a very transitional car.
The two previous Ford car lines, Standard and De Luxe, had blossomed into three, Special, De Luxe, and Super De Luxe. This time, the entry-level 136 CID (2.2 L) V8 was deleted in favor of a new 226 CID (3.7 L) L-head straight-6, the first Ford six since the 1906 Model K. The popular 221 CID (3.6 L) V8 remained as the top-line engine and was standard in De Luxe models. Both engines were rated at 90 hp. The 239 CID engine, introduced in 1939 for Mercury and trucks, was continued in the Mercury models. The chassis was longer, with a 114-in (2.9-m) wheelbase.
The "ignition key" for these cars was actually used to operate a bolt lock which, on one end, unlocked the steering column (a feature destined to return, mandated, decades later), and on the other end unblocked the ignition switch, allowing it to be operated. Starting the car was then accomplished by pressing a pushbutton on the dashboard, another feature destined to return with the advent of "smart keys".
Although starting cranks had been replaced by electric starters for decades, Ford cars included a manual starting feature until 1948 as an antidote to dead-battery syndrome. The wheel-lug wrench served as a handle (also for the jack) and the jack shaft with bayonet-coupling pins could be inserted through a small hole in the grille to engage a bayonet socket on the forward end of the engine crankshaft. A quick-and-easy twist of the handle was sufficient to start the flat head V8, and the bayonet coupling was self-disengaging for safety.
1946 - 1948
Civilian production resumed in July 1945, with an early start to the 1946 model year filling the public's thirst for new cars. The 1946 Ford was identical to the 1942 model under the skin, though a heavy new grille with horizontal bars and red accents modernized the car somewhat. The hood was widened by adding a center strip. One notable change was to use the 239 CID engine which since 1939 had been used in Mercurys and trucks, and capable of 100 hp (75 kW) for the first time. With steel in short supply, Ford produced a distinctive "Sportsman" convertible with wood side panels. The convertible had an electric top instead of manual one.

For the All New Scavenger Hunt #12 - A telephone but NOT a cell phone.
This grimy phone is in my messy garage. The garage is detached from the house so my hubby put a phone line in when he built the garage in 1983. The phone is approximately the same vintage. It's still plugged in and occasionally I get a call on it when I'm outside. I do own a cell phone, but I seldom use it.
Camera service tool.
Unknown for which camera and the exact function.
Probably for a Rollei camera.
A springloaded pushbutton with a circular surface mirror on its other side would perhaps indicate that this tool was used for lens collimation.

This is a project Iâve been gradually modifying since spring 2014: a full-size replica of Han Soloâs iconic weapon, rigged up with a small microcontroller programmed by Arduino to play sound effects and to make the muzzle flash blink! Making this project was rather difficult to the say the least, and I frequently ran into errors with the LEGO mechanics, the Arduino programming, the sound box, and the battery power â but nonetheless, Iâve succeeded in making custom toy function. Pulling the trigger makes the gunâs hammer and firing pin (with rubber bands) strike a momentary pushbutton, which is wired to the circuit board to pulse the microcontrollerâs sequence of blinking an LED and playing a PCM sound clip of Han Soloâs gun firing. The individual sound effect was extracted by me directly from the scene in Episode IV when Han correctly shoots Greedo first!
Microcontroller: ATmega328P-PU, coded with an Arduino Uno
Power: 2 AAA batteries (3 volts DC)

Using the polyphonic sound code from my electronic Dry Bones sprites along with the structural functionality of my illuminated mosaic Link portrait, Iâve combined both concepts. In this new portrait, I use a grid of flat LED panels fastened on to the rear door, with a 16 Ohm speaker attached as well. Controlling the whole circuit is a homemade circuit board with an Atmel ATmega328P as the central brain, containing an Arduino code for playing the music and activating the lights. The biggest technological feat for this project is how I successfully managed to control the 12V LED panels through a small 5.5V AVR, through the help of transistors.
In laymanâs terms, a small microcontroller like the ATmega328 is only capable of controlling circuits between 3-5.5V; anything else will burn out the chip. By using transistors attached to the digital outputs of the ATmega, I can control much larger loads, with the overall 12V input power being directed into the circuit via a voltage regulator. This new method allows me to control larger lights than simple LEDs, which opens new doors for potentially building more LEGO traffic lights and whatnot.
The physical LEGO portion was rather straightforward and didnât have a lot of flaws. Towards the end of the construction, I had to slightly rebuild the project to use a small tactile button to activate the circuit. Originally I had a large momentary pushbutton installed near the bottom of the rear door: the button required too much pressure to push, which caused the structure to wobble and almost fall over when pressed.
Creating the circuit board and wiring the Arduino code was also rather simple, since I used the same functionality of the Dry Bones model. Unfortunately, when I was testing out the method of using transistors for controlling the LED panels, I accidentally loaded the 12V power into my Arduino Unoâs 5.5V input â thus frying it. After purchasing a new Arduino, I successfully did some breadboard experiments with TIP120 transistors to control the LED panels.
The LEGO structure opens like a book, and on the rear door are eight white SMD LED panels connected in parallel to three digital output pins of the ATmega â cathode to cathode, with the red positive wires being channeled into the positive terminal of the 12V power supply. For sound output, I created some makeshift speaker holes on the top right orange brick sprite: this was achieved by placing LEGO grille tiles over headlight pieces.
The Mad Catz WWE Brawlstick is ok enough out-of-the-box, but wanted to bring it up to proper fighting game components (Sanwa stick and buttons).
Here's a "guts shot" of the next Harvestman module to be released, named the Double Andore. The module is a double function generator with a crazy amount of knobs, jacks, pushbuttons and LEDs. Mirrored text even! We expect stock end of March with a pricepoint somewhere around that of the Hertz Donut.

Although we've hinted at this for awhile in our front page news section, the cat is finally out of the bag! Introducing the next Eurorack module from Flame, the Tame Machine. The module looks like a lot of fun. In addition to being a tap tempo clock source and clock ("beat") divider, the module will act as a "playable" quantizer via the colored pushbuttons at the top. When not in Quantizer mode, however, they can be used as a mini keyboard for sending note data. The Tame Machine also has another fun feature- it is possible to record a melody from the mini keyboard and play this in a loop via the record function. So it will essentially record "sequences", possibly quantized, like the Roland Sh-101. More details forthcoming. LINK: flame.fortschritt-musik.de/news_preview2008.htm .

Here's the switch body in context. The slot in which the actuator used to slide is visible.
To the left of the switch is the big pink button for the Right trigger button. The dark object peeking out from behind that button is the butt end of the actual Right switch, a right-angle mount pushbutton.
The 1948 - 1953 Chevrolet Series 3100 half-ton pickups benefited from a redesign that took Chevy trucks into a new era of comfort, convenience, and style.
Chevy's restyled "Advance-Design" trucks were introduced in 1947, well ahead of its first new postwar cars, and little changed in appearance through 1953. The basic intent was to provide more room and comfort for occupants.
All Advance-Design pickups had a new bench seat accommodating three persons, instead of the old separate seats -- and for the first time the seat was adjustable for leg reach.
The cab, described as "Unisteel Battleship" construction, was larger in every direction. New extra-wide doors swung open on concealed hinges and extended down to cover the sills. Glass area grew considerably via a wider windshield, side windows, and backlight -- Chevy called the result "Observation Car Vision."
Interiors were more colorful than ever before on a commercial Chevrolet, and the dashboard was functional and more glittery.
Mechanical conveniences included interior door locks, a large steering wheel, new steering geometry for less effort, more conveniently positioned foot pedals, an accessory radio, roomy glovebox, and full needle instrumentation.
The 1948-1953 Chevrolet Series 3100 half-ton pickups also featured "four-fold ventilation" through the easy-crank-down side windows, cowl-top ventilator, foot-operated floor vent, and a fresh-air inlet on the curb side of the cowl.
Light-duty trucks in 1947-1949 came only with a 216.5-cid six; later ones may be 235.5-cid, formerly used in heavier trucks. For 1950, the 235.5-cid engine got a redesigned cylinder head, to become the "105 Hi-Torque" six.
Changes through the period included gray (instead of body-color) inner grille bars for 1949; vent wings, a lower rear-view mirror, and elimination of left-hand cowl vents for 1951; pushbutton (instead of rotating) door handles for 1952; and a slimmer hood nameplate for 1953.

In 2001 Bentley returned to Le Mans after an absence of 71 years, having last contested the world's most prestigious endurance race in 1930, scoring its fifth victory. Bentley's EXP Speed 8 sports prototype finished a creditable 3rd on its first outing at the Circuit de la Sarthe, and in developed form secured an historic sixth victory for the famous British marque in 2003.
To celebrate Bentley's renewed Le Mans campaign, the company introduced limited edition 'Le Mans' versions of the existing Continental R and Continental T models. This latest Continental had first been seen at Geneva in 1985 as a concept car - 'Project 90' - a mocked-up coupé intended to gauge public response to the idea of a high-performance car unique to Bentley, whose 1980s resurgence had hitherto relied exclusively on models sharing their basic architecture with other Rolls-Royce products.
When the real thing - the Bentley Continental R - was unveiled six years later, the waiting crowd burst into spontaneous applause. Styled with the assistance of consultants International Automotive Design, the Continental R benefited from computer-aided design and wind tunnel testing in the devising of its sleekly streamlined shape. Despite the need to incorporate non-traditional features such as doors recessed into the roof, the result looked every bit a Bentley, albeit one restated for the 1990s. Also new was the gearbox, a four-speed automatic with an 'overdrive' top ratio, but the main focus of interest was the newcomer's performance. Needless to say, this was outstanding, the combination of the 325bhp Turbo R engine in the new wind-cheating shape cutting the 0-60 mph time to under 6 seconds and boosting top speed to in excess of 150 mph.
For the exclusive 'Le Mans' variants, the 420 bhp engine of the Continental T was adopted together with a plethora of special features. The latter included flared wheel arches; green badges to the radiator, wheels and boot; 18" five-spoke alloy wheels; sports bumper package; four-pipe exhaust outlets; and 'Le Mans' wing badges. Interior upgrades consisted of drilled control pedals; pushbutton starter; sports seats with 'Bentley' headrest logos; stacked central instrumentation cluster with chrome bezels and green dials; dark walnut veneer with embossed Bentley badges; 'Le Mans Series' logo to the centre console; and a racing-style gear knob finished in chrome and leather.
This spectacular Bentley Continental R Le Mans was purchased by the current owner from Loris Kessel in Lugano, Switzerland, the official Bentley dealership in that region. It has been maintained by both Loris Kessel and Hessing Automotive (the official Dutch Bentley dealer), and later by Pon, which took over the official franchise from Hessing. The Continental Le Mans has been driven for some 145.000 kilometres, mainly on long-distance trips, and is in generally excellent condition. Accompanying documentation consists of Swiss registration papers and full Bentley service history.
