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.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
