More Portable Power

I’m working right now on a more portable ATX power supply, hopefully one that can survive a rough plane ride in the cargo hold without any special attention. I’d like to inset the terminals and switch, to keep them out of harm’s way and to allow me to stack stuff on the supply.

I think while I’m at it I will add a LM317 variable regulator and an Adafruit Panel Volt Meter to keep an eye on the voltage of the regulator. I could even add a current-sensing resistor, though I probably won’t need it.

I started off intending to roll my own supply, but it turns out they don’t get much smaller than the ATXs for what those do. I like having all the separate power lines, and the overcurrent protection is priceless.
