This instructable is for solar powered heart with a pulsing red LED. It measures about 2" by 1.25", including the USB tab. It has one hole through the top of the board, making hanging easy. Wear it as a necklace, earrings, bond on a pin, or hang it in a window. The possibilities are up to you, and we'd love to see what you do with them.
The schematic and parts list are included. You are welcome to wire up your own, copying is the sincerest form of flattery. We also have the kit available in our Store.
If you have soldered projects before, this will be easy. There are only 16 pieces to solder onto the board, and all but one is through hole. Depending on your soldering savvy it may take anywhere from 30 to 45 min.
So lets begin!
