The main job of the day done (call bank and arrange meeting to sign loads of forms) my mind wondered on to more interesting problems. I want a new keyboard for the next PC I am thinking of building. Trouble is no company make the type of keyboard I want (I'd soon go off the idea if it was available on ebay). So I was researching keyboard matrices and pondering if I could make my own on veroboard or make some sort of wiring loom. I have in mind to use nice sprung monetary switches with a "click". The humble PC keyboard is more complicated than you would think. I have a vague idea how it works, each key pressed completes a circuit on an X Y matrix and a controller translates this into standard info to send to the PC via USB or PS2 plug. Fine but I am guessing the controllers aren't standard, OK the output must conform to a standard but the matrix could be different for each manufacturer. Seems I need a keyboard to pull apart Which ever one I intend to use the controller out of I guess.

Luckily as I was contemplating all this bird_mad_girl phoned and invited me down the pub with her and dave_morrison for lunch, thus saving my already fragile sanity for another day.
