How to build a $20 47A power supply

[snellemin]

I was lazy and bought me a kit from this dude on rcgroups. It's a pretty good kit, if you don't have much time to custom make your own 12v-24v PSU. You basically just lift the ground off one of the legs on the second psu. Cut some wires and connect everything.

Just got mine hooked up and running tonight. I wanted something encased for taking on trips in the RV, and to keep debris out of the fans. After turning my garage inside out trying all the different cases I had, I noticed one in the downstairs "theater room to be" that I had walked past a hundred times in the last two months. Its just a basic Stanley plastic case, but it did not have any dividers or divider channels inside it. I didn't really want to used plywood, but it was handy, I had really gotten tired of overthinking this thing.
I put a base of 7/16" ACX down and screwed it in place to firm up the whole case. I then used 3/4" veneered plywood for the dividers (the center one has a 1.25" wide tee on the end of it to keep the supplies from sliding - although I doubt then will ever come loose. Next, I just cut a top piece out of 3/4". I used bar clamps to hold the entire thing together for putting the screws in - and predrilled the holes to keep them from splitting. But.. when running some screws in from the outside (to keep the "box" secured), I didn't use a big enough bit, and split one piece of wood (you can see it where the two cable clamps are screwed in for the input power cords).

I also used a STSP switch to to be able to turn it off and on. It fit nicely under one of the lid latches (however, it only turns red when off - its supposed to also show green when its on. Dont know what I did with the wiring on it....
Also drilled a bunch of holes for ventillation, and drilled two larger holes on the output side so that I dont have to open the lid to plug my charger in.
Turned out ok - if anything, I'd like to go back and make the plates out of nylon instead of plywood - but no reason to spend that money on it.
