Boards sold on makeymakey.com (since moving away from the US based SparkFun Electronics Inc for production) are made in China, are no longer open-source, lack the gold finish PCB (now silver), moved from AVR to PIC, and no longer Arduino compatible.

So who is making fake makey makeys?

[Edit]

It should be noted that the ShakeUp has a gyroscope, accelerometer and temperature sensor and has way more alligator inputs than product sold on makeymakey.com .

It is also made in Australia whilst being half the price of the competition...

I thought the guys who made Makey Makey made it open source and released the files for anyone to make and contribute back to.
