i have no problems with any one making a coop out of this that is why i open sourced the project. i have know idea where is the best place to get circuit boards made. i used PCB express for my last project. i use eagle for my own stuff with PCB gcode and mill my one off circuit boards. i am not real sure about all the design rules, i just make it work.
maybe you guys could talk RJ into making boards with a add on for wireless tx/rx. Hint Hint
and also this little unit works really well but if some one can stream line the code a little better than i did that would be good, i am not a strong programmer.
the only little glitch there is, on power up it starts in receive mode with the receive ISR running if there is no dmx signal coming into the tester for a little more than a second TMR0 will roll over and set the NO DMX LED. every once in awhile it will take a couple of button presses to switch to the transmit section, i think it is because it re-enters the isr and i havent figured out why. most the time this is never noticed but i like pushing buttons fast and repetitively.
any 20x4 parallel lcd should work. i just picked that one cause it was cheap and a nice size.
Thanks for all the complements
