Nice, that's pretty cool. How many amps were you drawing/pushing through the pencil.

nope hook up two wires to battery and the graphite works as a resistor and smokes up and glows

We weren't using a battery, but a high power power supply

wow, was that just your average piece of pencil led and how many volts did you pump into that sucker?
psyfertech 4 years ago
12V I think, and yes its an ordinary pencil lead, yes we intended to put too much power into it to watch it go incandescent, the exploding part was due to there being some moisture inside the graphite that got turned to steam.
