Badge design - step 1
Started building my poor imitation of the Defcon badge today; I am using uisp with the simple direct parallel port access circuit. I am going with the 8 pin ATTiny15L - don't want to spend time soldering smd stuff. A 3V button cell is the power source. The tiny15 is much more capable than the PIC10F; need some interesting ideas to implement. For Insignia 2006, I am asking students to demo some cutting-edge tools running on GNU/Linux; GNU Radio is perhaps one of the most interesting programs running on GNU/Linux. I would like to hear from people who have experimented with GNU Radio without using expensive and specialised h/w.
