VellemanK1823 1A Power Supply Kit

Great value for the price. It is cheaper than if you bought all the parts separately.

All is good, though I do recommend you replace the included 120 ohm resistor (just one) with a 220 or 240 ohm resistor. And don’t forget to use a small heat sink mounted with heat conductive grease on the LM-317 for all but the lightest of uses (under 100 mA).

All the Velleman kits are great and handy to have around.

Easy to assemble (I am skilled at this kind of thing. OK, I was a professional at this kind of thing for a decade or so....) Works well. I'm using it as a current limiter in a charging circuit, but the basic design would let you use it for any kind of 1 amp DC power supply from just about any AC input voltage. See the specs.

This kit has a bridge rectifier, allowing you to run it off of a transformer. Good quality.
