A Serial LCD controller based around an Atmel chip ( http://www.arduino.cc/cgi-bin/yabb2/...num=1260399444 ). I've not worked through what's involved yet but it could be useful.
wasyoungonce, thanks for your comments. Please feel free to float any improvements you can think of, I've been learning on the job with this. I'm very happy with the outcome but suspect that there will be a range of other options.

Excellent stuff Bob. The only thing I'd look at is maybe higher pwr Fets. I used IRF4095 "p" mosfets, $1.44 ea, capable, ...well in my design ...I've run at 4.8 amps per channel but recommend 3A per channel (with a simple Heatsink). I mean who would need more than 3A per channel I ask?
But that would mean a complete re-work and don't I know it...you have to settle on a design and stop changing it at some stage!
I am trying to work out the STA508A ATM...just a little confused by it. Its a H bridge driver?
But using an Arduino. Yep that's the ticket. Great work putting it on eagle PCB. I did as well.
Well done indeed!

the more I see of it the more I like!
