Sometimes I need a power supply, but I'm not always near a benchtop unit, or it might be impractical. I wanted a battery-powered unit with some reasonable current. Adjustable modules aren't expensive or hard to find, and some models include a convenient interface with a screen. The cheapest versions only adjusted voltage above OR below the supply voltage, but I found a pricier model with a wide output and suitable amperage.

I designed laser-cut wooden faces for all my parts. There was a 12-volt battery holder that adapts the batteries in my drill, a lighted rocker switch, a barrel plug, and the screen. Most benchtop supplies have a couple of banana plugs, but I didn't have any on hand, and a standard power connector is easy to utilize.

I did a test fit, and all the pieces fit on the first try! The holes around the outside will hold M3 hardware. I wanted to enclose the electronics completely, but it wasn't necessary and would add unnecessary complications.
All the parts fit
