This project was created on 02/24/2014 and last updated 2 years ago.
The new boards arrived, assembled one, and found there was a track error!, at least this one was minor, so a bit of cut/reroute solved it, and it now works as intended.
It has new features, like jumpers for "quick" calibration (you still need a tester to properly position the (calibration) pots, or you will have a very odd looking screen mapping, wich will NOT be square).
There is a video (vertical, sorry), with the working hardware here:
And the board is wrong...damnnnnn...the relay footprint is reversed (relays can be mounted on the underside...but, really?... I don't want to spend eight military grade relays on the board like that... I also had bad footprints for the USB, Xtal, forgot four resistors for the module (altough that wasn't a problem, could solder them instead of a header for the module) and in general, it could have some redesign around.
I would have liked it to work first time, but all in all, I'll treat it as a learning experience. I can now learn from my mistakes, do it again, better, more calmly (you couldn't believe how excited I was for doing my first board!)
I'll also add quick calibration jumpers, so you don't have to fiddle with the pots for that (25 turns are a bit too much for that, arent they?) Also, all is not wasted, I can use one board to develop the software, as simple as it is, it's better than a breadboard XD!
The boards finally arrive (who might have guessed? XD ) it's time to populate and play (if all went well)
