Wood burning, which goes by pyrography when it’s feeling fancy, has been an art form for centuries. PapaJ06 puts a new twist on it by using a microwave oven transformer to generate.

It’s a reasonable guess, but nope. Attempting to model physical processes like this in software would take a huge amount of CPU power. Even if it were not for that, not every pyrographically-modelled “tree” would end up looking like a respectable tree; there’s far too much unpredictability.What’s often used is an “iterated function system”, abbreviated as IFS. It’s a simple type of fractal. Wikipedia has an article on it.

A Google Image search on “IFS trees” or “fractal trees” will show some good examples of the output. There are likely some freeware programs that will let you easily play with them, but as it’s been decades since I’ve used one, I can’t make a current recommendation. A fire extinguisher would be a good idea too in case of firemicrowave ovens can also be picked up for free because people throw out them since they are so cheap.good sources are.1.

Recycling centers they can be sketchy since appliances and electronics can be treated the same. It’s amazing how people think warnings will stop people doing dumb stuff, its like laws/locks only protecting you from non criminals. If high voltage and big red letters of danger and wood catching fire doesn’t stop you doing something dumb, what will?Warning dropping a MOT on someones head is very dangerous and might kill them. Please do not throw microwave ovens at small children. Pets put inside microwave ovens then subjected to high power microwaving for 5 minutes may expire.Anyway, pretty neat project I do like watching the patterns form in the wood and interesting to see the pathways chosen, i guess some people just want to watch the wood burn.

Regarding danger. It’s OBVIOUSLY dangerous, so just telling people that it’s dangerous is pointless. 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:1) 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 rare, but it can fail.

In which case the capacitor may hold a lethal charge, possibly even for days or weeks. Always consider it failed, and short that capacitor to eliminate the charge prior to ripping out the MOT.

I have done it by bridging the capacitor contacts with needlenose pliers, with an insulated grip, while wearing a long rubber glove. Avoid touching the microwave case while doing this. Omnisphere 2 library download. Avoiding touching anything grounded too. 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.

If the capacitor was holding a charge, there will be a loud bang. Your pliers will have a nice scar on them, and might be spot welded to the capacitor contacts. Better them than you!2) No common wire has insulation sufficient to reliably hold back high voltage. Not even the most heavily insulated wire you can find at the hardware or automotive store. Don’t touch any part of a high voltage circuit when it’s powered, even an insulated wire. 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.

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. Sounds pretty cool, but seriously, don’t try that.

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). And while that shock in itself probably won’t be lethal, it WILL make you jerk in surprise; at which point you might touch something far more dangerous, that you would never intentionally touch.

I’ve used a large and long standard screwdriver (with a large resin handle) (with other safety precautions you mentioned), and for shorting big capacitors. As long as you don’t make contact at the very tip, even if the capacitor welds itself to the screwdriver, it can be removed and you still have a functional tool instead of potentially welding your pliers shut. A nice long screwdriver also can keep your hands (and you) much further away from the voltage (8″+ vs 2″-4″ with the needle nose pliers), greatly reducing the chances of accidentally contacting some part of metal case of the microwave.
