| 1) Bride of Frankenboard. I wanted the add-on board (to the left, with the blue sockets) to be somewhat serviceable so I created it to be removable. Originally I had a fantastic Arduino-shield like design with headers that the board would slot into, but there just wasn't space. At the moment this is the best option, but a later revision will be larger in design so that it's in fact serviceable and not just in theory (i.e without a ton of cables in the way). |
Alright -
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... |
 |
| 3) ...good enough for the purpose. I will try higher voltages, probably 24-36V, in the future as well as bulbs won't light up properly otherwise. Either that or actually converting to LED's... Also, note the washed out colors of the text. I have a solution for that as well, but that's a later issue. |
