Got mine all finished and it's in the system working perfectly. I left one relay without the 12v trigger signal to be used as a simple contact shorting trigger for the Crown XLS1502. Works like a champ.
Well Geebo got his working before me. He has a special need so I wrote a version of the software that takes 2 trigger ins that each controls 2 trigger outs.
I've been wicked busy with work so I just haven't had time to finish.
I'm taking my time making this look like a pro unit.
I should finish this weekend and will post a set of pictures of the completed unit.
I needed a logo for the front panel.
My first swag:
Very much looking forward to seeing yours completed, Chuck. Cool logo, too. Mine is in an old plastic VHS tape case tucked away deep within my rack and out of sight. But working marvelously. Thank you for that special code. A programmer I am not and I would have ended up building two of them.
Oh. My design has 8 LEDs! 4 are tricolour and will be driven by a driver chip. Under 20 mA maybe for the LEDs from the unit, multi colour and I have two ways to control brightness including a sensor for room brightness.
Here are some final pictures. I will do a final write-up with code later tonight or tomorrow.
Wow, nicely done! Makes me want to re-do mine but since it's out of sight I'll leave well enough alone for awhile. I like the small PCB for the Zener and resistor for the input. Much neater than connecting them right at the inputs like I did. Looks great.
