Pixel VGA, version 1 (Floor Cluster) - Garnet Hertz
Two dozen old computer monitors occupy the center of a gallery floor in a cluster facing the wall. Each screen is controlled with custom electronics to create pulsating and strobing patterns, casting a colored wash across the darkened gallery.
Dimensions: Variable (approx 3m x 3m). VGA monitors, custom electronics. 2011.

The MRF24J40MB is Microchip’s second 2.4 GHz Radio Frequency (RF), surface-mountable transceiver module. This new module adds +20 decibels per milliwatt (dBm) of transmit power via an integrated Power Amplifier (PA) and -102 dBm of receive sensitivity via the integrated Low Noise Amplifier (LNA) to the proven IEEE 802.15.4 compliant transceiver, PCB antenna and discrete matching circuitry. More transmit power allows designers to expand the range of their IEEE 802.15.4-based ZigBee or proprietary-protocol wireless networks.

Your heart is like Microcontroller 8051,
But now you have become old,
I’ve got a more developed technology,
That is 8052 Microcontroller.
You have only two timers,
TM0 for your family and
TM1 for your carrier.
But 8052 has three timers,
TM0 for his family, TM1 for carrier
And TM2 for me.
You have only five interrupts,
So you have no time for me
When I call you,
But in 8052, there is no
Problem of time, because
He has six interrupts.

The amplifier will be located out of sight within the retrofitted cabinet record player, so a microcontroller receives, processes and forwards remote control signals. This is an IR led pointed at the amp's remote reciever.
..lost and found my stash of ATtiny85s but not before finding every other component first - I need to do some serious sorting of my electronics boxes!

Closer view of switches and indicator lights. HiViz users will recognize the little potentiometer wheels for adjusting the delay and sensitivity of the Multi-Trigger circuit. The two LED's from that circuit are mounted above them. I also added the switch on the right to replace the wire connecting the photogate with the delay unit for disabling the trigger outputs. At the left are power buttons to both microcontroller and trigger circuits and below that a power button to manually open the valve for purging the line, and start button to run the program for dropping one or two drops. The blue DIP switches are used to set the number of drops, delay between drops and drop size - see label and program listing for more details.

The chipKIT™ WF32 is a prototyping platform that adds the performance of the Microchip® PIC32 microcontroller. The WF32 is the first board from Digilent to have a WiFi MRF24 and SD card on the board both with dedicated signals. The WF32 board takes advantage of the powerful PIC32MX695F512L microcontroller, which features a 32-bit MIPS processor core running at 80 MHz, 512K of flash program memory, and 128K of SRAM data memory. The WF32 can be programmed using the Multi-Platform Integrated Development Environment (MPIDE). It contains everything needed to start developing embedded applications. The WF32 features a USB serial port interface for connection to the MPIDE and can be powered via USB or by an external power supply. In addition, the WF32 is fully compatible with the advanced Microchip MPLAB® IDE and works with all MPLAB compatible in-system programmer/debuggers, such as the Microchip PICkit™3 or the Digilent chipKIT PGM.

Instructables
There's a small torch bulb on that pair of long wires, with the glass removed. A single transistor (BFY51) sets up a constant current through the filament, and by blowing on it, I can vary the temperature and hence resistance of it. This shows up as voltage changes, which are sent to the Arduino's analog input to control a sine-wave generator.
All the soldering is done. Four 16-pin connectors bring out the ATmega32's ports, while a six-pin header is used for programming.
My CMUCam4 has arrived (latest Sparkfun)- it's a Camera which you can control in detail via serial connection. It's especially usefull in conjunctions with small Microcontrollers (like Atmel AVR, ti MSP430, ti C2000, small Motorolla microcontollers, etc). You can train it to track collors or motion and you can use it's output in programms you can write for Arduino Boards for example. This is one of my first (completly underexposed :)) tracking targets (a sheet of paper illuminated by my bicycle lamp)
Power-over-Ethernet magnetometer. The microcontroller will be added after initial construction tests have been performed. This newer version incorporates some very minor revisions compared to the original design (retaining wire for 32768Hz crystal, minor track routing changes, decoupling added for voltage measurement and fan).

My continously variable, programable, 16x8 bank midi knob box. Originally built and designed in 2002, Somehow, I never gotten around to posting pictures until now.
The rather old 330Ω resistors are just a bit too big to put side-by-side on 0.1inch prototyping board. So, I've staggered them. A DIL resistor array would have been neater, if I'd had one available.

Parallax Inc. uses two milling machines in the production of hardware for products. These mills can cut different types of metals, such as steel and aluminum, which is frequently needed in the robotic kits engineered at Parallax. Many of the products we build on these machines may be more suitable for injection molding or metal stamping, but we really like the high-quality look, feel and finish of a milled and anodized aluminum part.

My final project involved playing some "music" thru my optical tape mechanism, shown in previous photos.
The final tape was made by a converting a MIDI file of me playing "Yankee Doodle" and an excerpt from the 1812 Overture. The snowman was synchronized to light up at the point where the canons are supposed to go off.
My original plan was to construct a "canon" by filling a blender with glitter and caps, but I had difficulty getting the caps to fire.
Due to spurious notes triggered by the boundaries between color bars, and speed changes incurred by human-powered transport mechanism, the music was unrecognizeable.
Note red boxes of "party snaps" used for audience participation portion of demonstration. When the snowman lit up, spectators were instructed to throw a snap and yell "Bad Snowman!"
Sadly, my camera ran out of batteries before the next, even more impressive demonstration: the GLOWING AND SPARKING PICKLE!!

When the Basic Stamp II microcontroller board is cabled to a PC running the Basic Stamp Editor program, my control program displays this terminal output on the screen after each press of the start button. It displays the control codes sent to the Firecracker transmitter, the DIP switch settings, and the resulting valve times used to deliver the drops.
