It’s enough charge you up to the point where you’ll receive a shock should you touch something grounded (like the aforementioned drywall corner, I’m speaking from direct experience).



Sounds pretty cool, but seriously, don’t try that. In a darkened room, you might even be able to see it as a faint blue glow surrounding where you’re holding the wire, with more energetic streams where specks of dust focus the current. Even if it’s a wire with insulation made specifically for HV, energy can still transfer through that insulation to you capacitively just like energy transfers to you through the glass of a plasma globe. Don’t touch any part of a high voltage circuit when it’s powered, even an insulated wire. Not even the most heavily insulated wire you can find at the hardware or automotive store. Better them than you!Ģ) No common wire has insulation sufficient to reliably hold back high voltage. Your pliers will have a nice scar on them, and might be spot welded to the capacitor contacts. If the capacitor was holding a charge, there will be a loud bang. You might not be aware of what’s grounded (a drywall corner surprised me with a nasty shock once, I didn’t even know there was metal in them), so basically touch nothing else and wear rubber-soled shoes to provide some additional insulation from anything in the floor. Avoid touching the microwave case while doing this. I have done it by bridging the capacitor contacts with needlenose pliers, with an insulated grip, while wearing a long rubber glove. Always consider it failed, and short that capacitor to eliminate the charge prior to ripping out the MOT. In which case the capacitor may hold a lethal charge, possibly even for days or weeks. Instead of just repeatedly pointing out the obvious, why not give some useful and specific recommendations for doing it more safely? Here’s a couple:ġ) The large HV capacitor in a microwave oven has a bleeder resistor, that drains the charge on the capacitor when the power is off. It’s OBVIOUSLY dangerous, so just telling people that it’s dangerous is pointless. Posted in Misc Hacks Tagged highvoltage, Lichtenberg, Lichtenberg figure, wood burning Post navigation doesn’t really show us too much about his process, but luckily recently posted a video of his process for riding the lightning. The contrast between the charred and intact wood, and the way the resin fills the voids really brings out the fractal nature of the Lichtenberg figures. We’ve seen these Lichtenberg figures before, but generally as electric discharges in acrylic sheets or crystal balls using multi-mega-electron volt accelerators. ’s technique is considerably simpler and well within the reach of most would-be fractal artists, relying as it does on a transformer salvaged from a $20 Craigslist microwave.īut the extra twist that really brings the wow factor to the fractal patterns burned into the wood is the addition of some phosphorescent resin to fill the valleys carved by the electric discharge. carefully prepares the wood, fills the burns with glow powder mixed with epoxy resin, and finishes with a little sanding, linseed oil and polyurethane. puts a new twist on it by using a microwave oven transformer to generate fractal patterns in wood. Wood burning, which goes by pyrography when it’s feeling fancy, has been an art form for centuries.
