DIY Adjustable Power Supply: Simple Build

If you are interested in DIY adjustable power supplies, you may want to take a look at this article.

Suppose you happen to have these materials: a waterproof junction box, a cooling fan, a 6A solar charging module, and a power adapter. If these materials have been sitting unused for a long time, you may suddenly get the idea to use them to make an adjustable power supply.

The production process is very simple. First, print out the positions where holes need to be made, attach the template to the box, and then drill the holes.

After drilling the holes, you can do a trial assembly.

If you want to improve the appearance of the cut surfaces and make the overall device look better, you can spray-paint the enclosure.

After spray painting, the cut surfaces become smoother and the overall appearance looks better. Then all you need to do is complete the simple wiring.

Once the wiring is completed, you can use the adjustable power supply normally.
