VoltWerks Lab Power Supply

A precision adjustable DC supply for lab and system use. VoltWerks has several features to keep magic white smoke where it belongs.

Frustrated after damaging another board with a hasty knob adjustment on a bench power supply, I created a no-knob lab power supply with a fast current trip, LCD displays and a few other cool features. Once the prototype was running I turned it into a crowd-funded project on Indiegogo. No more frying 3.3V circuits with 10V!

Enjoy this project?

Good question Evan. The short answer is that I don't trust myself with knobs. Most of the circuits I mess with have tight voltage requirements (1.2V, 1.8V, 3.3V...). It's too easy to thoughtlessly bump the voltage. Also I figure how often do I really need to adjust the voltage? With a low-cost supply I can set the voltage and leave it attached to the project. That said I haven't ruled out a future power supply with knobs.

These look like a nice addition to a bench, and a low cost way to get a PSU. My concern is with the trimpots used to control voltage and current. I'd really like to see knobs instead... any reason you went with the trimpots?
