This is pretty cheap...i cant wait until i can mod my bluetooth mouse into a controller and use it like a stackmat.
On another note: isnt there a cheap alternative to stackmat timers that work with cct?
Mouses aren't very expensive these days (especially wired ones... but you can get wireless laptop mouses for like €5 around here I believe)
And you don't really need much else (maybe a few wires, I used the buttons that were originally in the mouse and put them in some CD cases as touchpads)
Though my mouse suddenly stopped working, can't figure out why
