This is the new Arduino Revision 3! It sports an updated USB controller chip (was an atmega8u, now an atmega16u), duplicated Analog 4 and 5 pins next to the AREF pin (for future shields) and an IOREF pin next to the reset button (to let shields know the I/O voltage of the pins.)
Also, the reset button has moved next to the USB jack to allow for easy access when the shield a shield is on top.
Everything else is the same, processor, driver, board size, upload speed, etc, so it is compatible with all current shields and code.
Amazing Vintage Look! By using the easy to follow instructions provided and a few simple tools, the Saga TT-10 Electric Guitar Kit makes it simple. Hack it and make it your own!
Commercial Geiger counters can cost hundreds of dollars. With this Geiger Counter Kit from the Maker Shed you can build your own at a fraction of the price! This easy to solder kit can be built in an evening and it works just like you think it would; clicking and blinking in the presence of radiation. Is grandma's dish collection radioactive? Do bananas give off radiation? Are your granite table tops giving off gamma rays? After you build your own Geiger Counter you'll be able to find out!
The Bluetooth Arcade Controller Shield created by Wayne & Layne fits on top of an Arduino Mega and shows up to your computer as an external keyboard. Wire up some arcade buttons, map the buttons to replicate a button on your keyboard, and you'll have a wireless controller for your MAME cabinet.
