Recent hardware hacks
An input converter for the Phidgets InterfaceKit - when you run out of digital ins, you can use some of your analog inputs with this handy little board. 10k pull-ups hold the a2d converter pin high (5V); pressing a button/switch/etc sends the sends voltage to 0.
I based the new d.tools controller board on the chip45.com crumb128 - much smaller than before and finally USB support.
d.tools media player prototype I took to UIST. Cut out of 1/4" acrylic on a Lasercamm.
mechanical prototype for a "drawer" tangible UI I am working on with Merrie Ringel for the Diamondtouch table. Didn't add enough space on this one so the push/pull action had way to much resistance.
Next iteration on the drawer - this time with built in slide pot for drawer position sensing - and all hooked up to d.tools. The USB key is used to hold the "stuff" that projected onto the Diamondtouch table when you pull out the drawer mechanism. That was probably not very clear as a description...
