Grenade - passthru with varivolt.

[slimest]

I made this power supply from a chinese lighter. No accumulators inside - it takes power from 12V AC-DC adapter. Varivolt made from KIS-3R33S. Cheap and good looking thing
Output voltage changes from approx 3V to 8V.

Really cool mod you made. I wouldn't take that to the office though, you may freakout some people.

Awesome!
Of course you know you're now on a watch list, right?

Yes, I intentionally made it only for office/home use. Taking a grenade, even fake one, somewhere outside is not a good idea.

Yesterday I tested the grenade under load. Measured voltage drop. Here are results:

7.9V - load with 5ohm - 7.77V
3.3V - load with 1.5ohm - 3.16V
