game controller build thread (wiimote, analog, Cherry Red, Leonardo, LoL)

[Camineet]

friends,

hands have rsi.  off the shelf not adequate.  have come up with following so far.

one-handed controller.

build 2 for switching hands every month or so.

internals of wiimote for IR pointing only.

arduino leonardo for all other controls

vita analog stick for cam control.

3 cherry mx reds around analog.

4 cherry mx reds on grip

4 cherry mx reds on panel opposite of other 4 cherry reds with keycap tops facing back of finger tips (finger pull actuates a key as well as finger extension).

11 keys total. xpadder can make needed 24 keys to play LoL with alt button map toggles.

electronics such as leonardo board all housed in separate polycase project box.  so, controller => project box => pc


learn autodesk and draw housing (something like an enhanced wiimote overall), friend will 3d print for free.

many questions.

first is, how do i connect this

after reading another post on gh in which a member switched to wacom bamboo, i watched a youtube of LoL played /w one.  ty Sc0tTy for that post.

decided to build my custom controller without wiimote integration.  pen pointing is clearly superior in certain ways important in LoL, and i'm going with that. 
 
will still build controller for alleviating current/future finger issues with all the features i mentioned before.

help greatly appreciated.
