On that "somewhat depressed and disinterested" topic... I spent a week moping, and seem to be back on form. I've got a couple of projects under way, and since I asked for help on one forum and got a whole bunch of cool stuff in return, maybe y'all can help out. The three that I can talk about:
First is the simple one. I'm building a couple of special-purpose timers to let us be far away when the liquid propane powered bottle rocket ascends. I've got a bit of code written and the interface electronics figured out (a couple of 2N2222s and diodes driving relays which then trigger the valves) to do this with the Atmel AVR1200 embedded microcontroller, but I need to interface a display. I could hack together an LED display, but http://eio.com/ has backlit LCD displays for less than the LEDs alone would cost me. Anyone out there played with such things and can give me guidance?
Second, I'm collecting parts for a tandem side-by-side tricycle to be used as a base for some kinetic sculpture. Old bikes in the SF Bay area that you'll let go cheap? Experience with brazing that you're willing to pass on?
Third, I'm building a large environmental sculpture for Burning Man, sort of a "garden of eden" theme. If you're into the non-flammable side of the event, or would like to be, or are interested in sharing a truck to get all this stuff up there in August, drop the webmaster a line.
