Maker Shed is running a good deal on its Mintduino and Mintronics Survival Pack kits. You get both for $29.98.
The MintDuino is the newest product in our Mintronics series of kits. It’s perfect for anyone interested in learning, or teaching, the fundamentals of how micro controllers work. Inspired by Tom Igoe’s Arduino tutorials, the MintDuino will have you building your very own ATMega based micro controller from scratch on a breadboard. Afterwards, you can easily programming it from almost any computer via an FTDI programmer (not included) and the Arduino IDE.
