I love running 40V across 0.5mm pencil lead and watching it evaporate into gas in a flash of blinding white light :)

@skobkin no, 40V but i should have said 3.2A since it is current limited and for short runs of pencil "lead" it is only running at about 5V.

@skobkin That said I have run it at high voltages of (40ish V) and it goes up almost instantly at that voltage/current. Just not what I'm running it at today.

@freemo
Yeah, I guess 3.2A will make it quite hot too ๐Ÿค”
Need to try that myself I guess.

@skobkin just use it to short a 12V car battery and it will go up pretty fast.

@freemo
I have 4 UPS batteries at my disposal, but they're perfectly balanced and I'm not sure if I should do that to them.
But I have a couple of power supplies. Can use them. Still need to buy this graphite for pencil though.

@skobkin if they are lead-acid batteries they should handle it fairly well... if you hook them together (series or parallel) they should remain balanced..

that said just short one of your outlets, lol. The worst that could happen is you burn your house down :)
