Hobbyist Erik Kettenburg was concerned that the size and cost of Arduino stifled his ability to craft, so he set about developing Digispark. It's an Arduino-compatible board, the size of a quarter, that offers a few pins at around a third of the cost of an Uno -- so you don't have to worry about taking projects apart when you're done. Designed to be fully compatible with the Italian standard, it's packing six I/O pins, 8k memory and a full USB connection amongst other things. The aim is to retail the gear for $12 a piece, and has been so popular that it's made nearly $100,000 in Kickstarter pledges, smashing its original goal of $5,000. We've got video for you below, and you can still throw some cash Mr. Kettenburg's way if you fancy getting your hands on one quickly.
