Well while I wait for my new batteries for my Duop V1 I decided to make a Variable Benchtop powersupply.

SPECS:
1.2V to 15V Adjustable Range
1.5A max current output
120VAC input
Digital readout of voltage and current draw of attached devices
Full bridge rectifier and step down transformer
Cooling fan to keep the box from burning
Protection Diodes encase I stick the output on some high unknown voltage
Chrome knob
Authentic Oak wood casing

I will post a schematic and parts list on Monday. Oh and more info to

Again with the wood.

Just kidding, that's awesome! I made a similar thing with a computer PSU.

Wow! I love it! It has a wonderful old-fashioned look. I think I'm going to do some price checking to see how much purchasing every part costs. I've been wanting a bench top power supply for a while, but the cost held me back. This looks exactly like something that would get on Make.
