blue LED POV and the Diecimila hack
I really wanted to make something cool with my new toys before the last make:philly meeting. I knew there was not much time, so I settled on a POV device. I figured that would be easy to show off, and would be a good way to interest people in the hacktory arduino/freeduino class. As it turned out, the hardware was the easy part. Here you see my attempts to get it to spell MAKE. Obviously I still had some work to do...
I found these great little smd leds on a junked keyboard pulled from the trash. Soldering them down with their individual current limiting resistors was a challenge. Unsoldering them from the keyboard was a nightmare! In the end I only ruined one. I really want to build a hot air rework unit.
Along the way I came across this post. Pure freakin' genius! I used an smd cap instead (because I had it and I am addicted to soldering tiny things), but other then that I can't add anything useful other then to say it works like a charm.
