AC Drill Speed Controller
I like the idea, but I would use this sparingly. Running an electric motor at low voltage can damage the motor. The motor will run hot and wear out quicker. http://ecmweb.com/content/how-save-your-motors-dur...Dremel used to offer a variable speed controller box you could plug your Dremel (or other tools) into. It kept the voltage constant at all speeds so your tools were safe. I believe it modified the frequency instead of the voltage. There's probably something similar out there that would do the job without risking your tools.

Thanks for watching
Thanks for watching. I forgot to mention, it can measure from 3v-30v DC
If I understand properly you use the source to measure as a supply for the voltmeter ? So you can't measure small voltages under 2V and your voltmeter highly interferes with the precison cos you must feed it.
excellent instructible.Thanks for sharing.
