Reflection (6.10.17): After discussing my outline plan with my lecturer James Humberstone, he very kindly lent me his Bare Conductive Starter Kit. This is the next level of Makey Makey and will automatically solve some of the problems I've been considering in my project such as how to use Makey Makey without the clunkiness of having a computer and wires everywhere. Neither appear to be iPad compatible but the Bare Conductive kit allows you to just use the motherboard using an Arduino which just requires power, and paired with it's own speaker jack, releasing the need to be next to a computer.

Yes it is washable conductive paint!
