High-:publishVoltage Fractals

Posted on by

Int 1777, Georg Lichtenberg found that discharging high voltage on an insulating surface covered with a powder, a fractal-like image appears, sometimes known as a lightning tree. Incidentally, this is a crude form of xerography, the principle that lets copiers and laser printers operate.

[PaulGetson] had a high voltage power source from his Jacob’s ladder experiments and decide to see if he could create Lichtenberg figures. Turns out, he could.

If you have a source of high voltage, the rest of the project is pretty simple. A piece of plywood serves as the insulator and baking soda crystals cause the …read more

Arc Lighter become Plasma Pyrography Pen

Wood burning can be quite a striking art form, but who wants to be stuck using an old-fashioned resistive heating element to char wood? You could go with laser engraving, of course, but that seems to take too much of the human touch out of it. So why not try a mini plasma pen and blow torch powered by a fancy cigarette lighter?

Arc lighters are rechargeable electronic lighters that look like a tiny stun-gun, and [NightHawkInLight] has been coming up with some interesting hacks for them. In this case, he extended the electrode leads out and mounted them to …read more
