David Pride, who previously created the wonderful motorised Connect 4 game (which handed me my butt at the Big Birthday Weekend), recently went to a car boot sale and found an “air drum” kit for £1. Taking this as inspiration, he has worked out how to connect two Wii controllers to his Raspberry Pi via Bluetooth and then play drum samples depending on the position and action of the controllers. Voila! A DIY air drum kit! You can read more about it here and download the code here. You can see the kit in action below.
