Laboratory power supply
Update from 01/30/2023
Since the housing cannot be printed on 3D printers with the maximum dimensions of 200x200x200mm (housing dimensions: 105x170x210mm), I divided the housing. There are now additional STL files (split housing-1.stl and split housing-2.stl), which you only need if your printer cannot cope with the dimensions of the housing. You have to glue the two halves of the case together. I glue PLA with superglue.
Update from 01/23/2023:
I made a mistake with the size of the load resistance: 10 ohms / 15 watts is correct. But that's not so accurate. 8 ohms would work too. The 15 watts are quite oversized. 5V and 10 ohms result in a current of 0.5 amps and thus a power loss of 2.5 watts. But the higher value won't get that hot.
Sorry, but I don't get a Remix entered.
This laboratory power supply supplies constant 3.3 V DC, 5 V DC, 12 V DC, -12 V DC and a variable voltage of 0-24 V DC. It's a modification of my lab power supply https://www
