Gamepad iPega bluetooth (diy foot controller)
Well, I have tested several types of foot controllers bluetooth from blueboard up versions created from a QWERTY keyboard.
While blueboard has few command keys, diy foots with the QWERTY keyboard are fragile and somewhat durable.
I'm researching the gamepads with bluetooth. The ipega pg9017 seems to be compatible with iOS in text mode and has 13 keys.
I've seen some projects converting a gamepad (wired) in foot controller adding contact keys.

I think for loopy can get interesting.
Does anyone have one of these to tell if it works?
