My guess is that even though there are provisions for two batteries, both batteries are in parallel and must be the same voltage. Without a schematic of the PDB, I can't be sure of that, but it seems logical.

I sent a question to the people that sell these hoping they can answer this, otherwise I'll hook a meter up to it tonight when I get home.

If I end up with a custom designed board, this shouldn't be an issue.

 

Here is an updated schematic. It is based on using a strip of 12 LEDs of each color, and I think it's essentially complete. It should all fit on a 1.5" square PCB.

 

The resistor had the number 151 stamped on top of it so I'm assuming it's a 151 ohm resistor?

Pretty close, it's a 150 ohm resistor, just by coincidence.
The last digit is the number of zeros to add on the end of the other digits so:
150 = 15 ohm
151 = 150 ohm
152 = 1500 ohm
etc

 

Jeff,

Attached is a picture of your controller with hook-up information. I'll put it in the mail to you on Friday, 3/22/13.

It has been working flawlessly for 6 hours, so it should be solid.

I'll try to shoot a video if time permits.

ETA: No video, no time.

Charles, I owe you more than thanks! I really could not have done this myself and appreciate your willingness to help me out. Tell me what I owe you for your time , trouble and parts and I'll send it your way!

Thanks again!

 

No charge. You are welcome.
