Keep up the good work, HAK5 is now a weekly discussion in my computer repair and Cisco networking classes.
Keep up the microcontroller stuff, it adds a nice mix to the SW / HW hacks. If you are looking for any topics, the Lego mindstorms NXT community has a few really cool projects.
I'm currently playing with these two projects on creating an 'inverted pendulum' (aka Lego "Segway"). One uses NI Labview, but the other uses a really cool Bluetooth to Wiimote link that requires Cygwin, Ubuntu and python to control the link and interface the NXT controller, with the Wiimote.
