Atmel put out some new, small microcontroller chips early this year, and we're just now starting to think about how we'd use them. The ATtiny102 and ATtiny104 (datasheet) sell for about a buck (US) a...

Hackaday was at HOPE last weekend, and that means we got the goods from what is possibly the best security conference on the east coast. Some of us, however, were trapped in the vendor area being a…
