Competition Robot, 1998, electronics, various other materials. Working with my team, I built and programmed an autonomous maze-running robot for the culminating ME218 smart products course taught by Ed Carryer.

iTonk, 2016, electronics, toy, iPhone. I modified a construction toy for very remote control. A person video conferencing the toy's phone can go forward, backward, lift the front loader, and make construction sounds by shining a small light into their phone's camera different directions.  Sensors attached to the phone's face pick up the light change and signal the toy to respond. The person controlling the toy can see where they are going through the toy's phone.

Tappers, 1998, aluminum, aluminum, solenoid, steel, plastic, electronics. These tappers were mounted in an atrium, each hit a material with a different sound. The percussion of each was controlled by a key word searched for on various internet news sites. This hour's amount of "war," "famine," "happiness," "relief," "weather," "justice," and "truth"  was sung, giving an intuitive sense of the world. I worked with a CS student to make an interface. He programmed the Java code and passed bytes to my programmed PIC which sent control pulses to the tappers.

Emotes this one is called Draw, 1999, various materials, motors, electronics. I wanted to get more human kinetic communication from the computer. Each Emote has an action and purpose, and each is controlled by a remote loved-one using a simple motion based on-screen interface. The computer output specific input dependent bytes that I then translated into actions using a PIC processor.

Spray, 1996, steel, hairspray, lighter, solenoid, concrete. I made eight of these flame throwers, each crowned a 6' tall steel and concrete stand, and was arranged in a semi-circle. I programmed a PIC processor to fire them in an orchestrated concert. You can't hear the burning sound in the photo, but it was fantastic. Inspired by the syncopated fountains made by Stanford alum Mark Fuller at WET.
