kit build - CC/CV linear power supply

I felt like doing a kit this week. So I did. This is a constant current / constant voltage DC power supply. It claims to be able to make up to 3 amps and 30 volts from an AC input. But can it live up to the claims? Here's the link to the kit on Aliexpress: http://pileofstuff.ca/r/l90jm ----- My tip jar:   / pileofstuff   If you are OK with me getting a commission on your purchases, feel free to use my affiliate links: Ebay: https://ebay.to/33IF7PA Banggood: http://pileofstuff.ca/r/9ajsf Some other links to products may be affiliate links https://odysee.com/@pileofstuff ----- This isn't the only way to do it. It's probably not the best way to do it. But it's how I do it.
