Furan dug into an LED message scrolling badge to gain custom control –
This is one of those el-cheapo led nametag badges. The inside of the badge had one of those gloptop chips between some pads for a smt chip, so I dremeled out the gloptop, reverse engineered the schematics for the board, and hooked up an AVR. This is just the start, coming soon I’ll do this with a white and blue badge, completely self contained with (hopefully) decent PWM effects
Total removal is certainly one effective way of dealing with the problem of manufacturer’s “black blob” IC’s.

hey, I’ve acquired one of those cheapo badges and am just about to start hacking it using an arduino board, im a complete newbie so do you have any advice on pitfalls before i start?
hmmm, haven’t worked with one myself. Maybe try drpping a comment on Furan’s video over on flickr –
