Building a Modern Power Supply for the Commodore Plus/4

Check out our sponsor https://www.pcbway.com for all your PCB needs, starting at $5. The foot-warmer brick-of-death power supply that came with this Plus/4 needs to be replaced. Urgently. Before it destroys the computer. These power supplies are notorious for failing, and when they do, the voltage regulator shorts its output to its input, sending lethal voltages to all the chips in the computer. But we can make a brand new one that's safe and reliable. And all it takes is a 9 volt transformer, a small 5 volt Mean Well, a bit of soldering, and some 3D printing. Oh, and an LED. Because you've got to have LEDs. BTW this build will work equally well with a C64 or C128, all you need is the appropriate plug for the computer. Obligatory warning: mains voltages can be lethal. Do not attempt this project unless you are comfortable working with mains voltage and know what you're doing. The mains here is 240V, yours may be different.
