I had a post a while back on charging an iDevice (iPhone, iPad, iPod) and talked about and showed a schematic for the charging circuit. This design is based (and the schematic is almost exact!) off of Ladyada’s Reverse engineering Apple’s secret charging methods. (video link, it’s good, you should watch it!) I give her full credit for the circuit. Now, the boards I whipped up in a few hours, and had it made from DorkbotPDX service. I sent off the files and 2 weeks later, I got three perfect purple PCB’s. The boards cost a total of $4.69. Shipped. You can’t beat that with a stick! Now, I have a nice little iDevice charger that accepts standard 5 volt power from any standard power supply. Although I do tend to favor 5V 2A supplies from Adafruit.
