Circuit boards mounted on the new frame. Nicer-looking and more compact than the Crudely-Sawn Wood Scrap™ rig, definitement (as they say in France).
I need to build some new cables before this will work.

These are pictures documenting the completion of a full upgrade performed on my VGA Synthesizer.
The VGA Synth is an audio video instrument utilizing hybrid analog-digital technologies to hack standard VGA signals to produce a synaesthetic audio video experience. With the aid of an external audio mixer, line-level outputs on the VGA synth are routed to its inputs, creating oscillations through networked feedback loops. These oscillations are translated into sound through the mixer and visuals via custom electronics inside the synth. Additionally, internal oscillators synchronized to the VGA signal are used to generate vertical bands. To provide a bit a variation to the patterns output by the synth, a 3x3 switching matrix with automatic and manual controls is used to reroute signals on one of the three input channels to any combination of the three output channels. The three outputs correspond to the red, green, and blue levels in a VGA video signal. The automatic routing control is derived from the level and frequency of the signals on the input channels.
Originally developed in the Spring of 2007, the VGA Synthesizer features included 3 analog line-level inputs, 3 analog line-level outputs, one 15-pin D-sub VGA input, one 15-pin D-sub VGA output, gain control for the 3 line-level inputs, 3 oscillators synchronized with the video signal's vertical synch pulses, and amplitude controls for the 3 oscillators.
The original chipset included TL084 and TL082 operational amplifiers; CD4040BE, CD4066BE, CD4050BE, and CD40106BE CMOS 4000 series digital logic ICs.
In 2010, the revision eliminated a lot of unstable non-inverting amplifier configurations in favor of an improved system of higher gain inverting amplifiers. Many redundant components were removed; the power supply was simplified and redesigned to produce less line noise; additional manual control over the 3x3 routing matrix was integrated using rotary switches; and the oscillator amplifiers were made independent from the line-level input amplifiers. Finally, the chipset was upgraded from the slow TL series of linear components to the high slew-rate TLC series and the CD4000BE logic was replaced with HEF4000BE.
This was making springs, about one every ten seconds, live on the street. Wire is coming down from a roll on top, and the spring is coming out between the two pulleys. I have heard stories that they used to actually do this in America, about 50 years ago. (In the downtown Seoul electronics market.)

From some t-shirt scraps, I sewed a pocket to hold the arduino and battery. I added snaps to the pocket and snaps to the back of my dress, so that I could hang the arduino from my clothes. This way, I could plug all the wires into the arduino and be sure they were in the correct pins, and secure them with some tape; put the arduino into the sock; and ask my co-worker, when it was time for the party, to simply snap the sock to my dress--easy.
Similarly, the switch for the red eyes is connected with snaps. Wires (that plug into the arduino) are soldered to the female halves of the metal snaps. The male halves are sewn with conductive thread to my dress. (Conductive thread! Yes!) The conductive thread runs inside my dress, down to my hip, and terminates in two safety pins. I threaded it inside bias tape to prevent the two threads from touching and causing a short. When the arduino wires are snapped to the conductive-thread snaps, the arduino is connected (conductively) to the safety pins. When I touch the safety pins to each other, I close the circuit, triggering the red-eye effect.

Experiment in drawing moving vector dots on a video vectorscope using an FPGA to synthesize a chrominance signal (using only the luminance channel) that is slightly off the colorburst frequency, causing the rotation. The synthetic D1 video signal is sent to an encoder chip to create the analog video signal.

All controls are external. B500k potentiometer in place of the "wave shape" switch. External "gain" control. I also opted for a C100k "rate" control instead of the linear taper. This seems to spread the usable range out nicely.
A schematic diagram for an upcoming project: a crystal set receiver based on the Australian "Mystery Set" designed in 1932 (it's called a "Mystery Set" because the tuner is an incomplete circuit and yet, performs better than a "correctly" designed set). The set will be housed in a wooden box with a lid with lock and key (in the style of an old English crystal set) and a dummy crystal detector for looks only (the actual detector will be a 1N34 type germanium diode). This radio will also have a band switch for longwave, medium wave (standard AM broadcast), and shortwave. Note the use of inductors in series and parallel combinations, and the use of a second detector diode for the signal strength meter. See www.flickr.com/photos/14275763@N08/24133301200/ for photo of some of the parts.
Note: To cover the European LW broadcast band, use 230 turns on L2.
Bought a new computer a few days ago. HP Pavilion dv7-1245dx Entertainment Notebook. So far, I am loving it. Under $800 but still had everything I need.
