Help to build a quick and dirty POWER SUPPLY

[Ronj]

You can use a power supply from an old computer. Check out the videos on YouTube and make sure you get the on/off switch first. You can get 3 low voltage outputs from it. I built a foam cutter from one using the heating element out of a toaster. I didn’t get the switch right so I just plug in and unplug but works just fine. Good luck.
