"HiJack is a hardware/software platform for creating cubic-inch sensor peripherals for the mobile phone. HiJack devices harvest power and use bandwidth from the mobile phone’s headset interface. The HiJack platform enables a new class of small and cheap phone-centric sensor peripherals that support plug-and-play operation."

"The Gloves are a cutting edge experimental gestural music ware being developed today for the purpose of Imogen Heap’s studio and stage work. Using a unique gestural vocabulary, motion data-capture systems, and user interfaces to parameter functions developed by Imogen Heap and her team, artists and other users will be able to use their motion to guide computer-based digital creations."

"The Science Tricorder Mark 2 was a wonderful adventure of discovery to develop. It’s my pleasure to be able to share it with you…..The Science Tricorder Mark 2 was planned during Spring 2008, and actively developed starting August 2008 until December 2010 — largely over my fourth and early fifth years of graduate school."

"There are many methods capacitive sensors can be produced. A simple one way to form an on-off output is by using two layers and a spacer in between. Through a voltage to conductive objects causes positive and negative charges to collect on each object."

"So I decided it was time to build a kegerator…More importantly, because I’m a nerd and I’ve never worked with an Arduino I decided it would be fun to play with one. I ended up with an Arduino controlling an LCD for each of the 3 taps I installed, displaying what beer is on tap and how much beer is left in the keg."

"The following page documents the construction of a rather large electric scooter for ‘semi-offroad’ use. My goal was to have something usable to zip over to a train station or grocery store, regardless of it was snowing goblets of ice outside. This project unfolded slowly over the course of ~18 months, in a start-stop fashion, as time became available."
