So I've been teasing a little with dribs and drabs of info on this. At last the boards arrived!!! I'll start soldering up a few over the next week or so I still have some parts on their way, though these are local so should take no more than a week or two to get in.
The project was derived from Ardbir which derived it's origins from the original Matho's controller. The board I've created is a bolt in for Lael's kit purely to make initial testing easier, I'm still to sort standoff sizings, but screw holes seem to line up ok.
This first board has some screen printing missing (hey it's my first try, something had to go wrong), lets just hope the workings are all there. I'll be soldering up three of these, then make some updates; get the screen print right, and get some more printed.
Pic to come.
