My version two charlieplexed lighthouse circuit PCBs (charliediscs) have arrived back from the Seeedstudio’s fab. I used the same deal as for my last boards, this time it took around 3 weeks in total. That’s pretty good for 20USD!

I thought I’d have a go at getting my PWM controller PCB made professionally.

I’ve updated the code to my LED strip driver and included a few new features.
Here’s a quick demo video.
[UPDATE 7 Mar 2011] Added input/output graph plus link to download LUT calc excel file.
[UPDATE : DEC 6 2010] I’ve had some proper PCB’s made for this circuit. More info here.

I have been playing around with building a lamp for my desk using a LED strip and constant current driver that I bought from Deal Extreme a while ago combined with a PIC12f683 to provide variable brightness via Pulse Width Modulation (PWM).
[UPDATE OCT 20 2010] I’ve updated the firmware for this project to include new features. More info and firmware download here.
