Power Supply Board
So this is midway between me finishing the install of the lights in the FW200 and today (date of shot, 3rd Jan 17).
After fiddling about with a few audio based circuits on a battery, I decided that I needed an actual power supply.
(It's amazing how much difference half a volt makes to a circuits performance.)
It's a simple enough circuit inside, a switched jack for the input, that feeds two switches and each has a status LED.
The three wires are Black to Ground with red and blue both being positive. It can be powered by a 9V battery.
It is mounted in a 2gang pattress box with a bit of old skirting board for a face plate.
I could've bought a purpose made blanking plate as a cover/lid but it was built late one evening and there wasn't one to hand.
