Our finely-wired friends at Solarbotics have released their latest Arduino kit, the Ardweeny, “the smallest Arduino you can build yourself with through-hole components.” I love the backpack PCB concept which puts the support electronics for the ATmega328 chip on a board that stacks on top of the chip and is soldered to the chip’s pins. The Ardweeny is a Solarbotics riff on Kimio Kosaka’s One-Chip-Arduino.
