So, working off Frank's idea to hardwire a dash switch into his garage door opener he sent me a switch and my ideas started to flow.
I live in a gated community (where else would a guy that only works 1 day a week live?) and I have a two switch remote that runs off of one of those 3v disk batteries that die rather quickly.
I went on line to find a stepdown transformer (of sorts) that would take 12v to 3v so I could hardwire the power source for the remotes as well as the two switches.
I bought this kit out of Hong Kong for $13 and put it together per instructions:
I was a variable step-down that would change 12v to a few different DC voltages. I built it and tested it the same day Frank texted me to see how it was going.
The result was a bit explosive:
A catastrophic failure - back to the drawing board.
I found another step-down out of China this time that was pre-figured for 12v to 3v - $9.00
When it came I tested it and a reliable 3v came from the leads.
So here's what I put together:
I used doorbell solid-core wire instead of a regular low gauge wire because it was easier to solder onto the back of the remote circuit board.
Everything works great now and I'm more like Frank - well actually a little better in this case.
