So I've created a daughter board to the light board made from an old obsolete switchboard, hence the bulky blue sockets, containing all N-Channel MOSFET's to allow for logic 5V switching of loads independent from the logic (i.e > 5V). Link to circuit.
Seems to be working fine so far!
The downside is that it's hideous. And slightly erratic in its dependency, as it seems to have a glitch somewhere, but I can't see or find it. So I guess this board will have to be a sort of "proof of concept".
But it does work.
And that means I can continue with other stuff.
|2) Ignoring the broken magnet holder, here's an active light with 12V (i.e around 1.5V due to duty cycle). |
Still not super bright, but...
