Includes the PowerLabs Microwave Gun, for long range cooking!

The experiment was repeated in a microwave oven and the yield was compared.

For processing of tissue samples in the Microwave Processor.

I have 4 unmodified MOTs. The first two have their core connected to ground, and the primary windings in parallel. The two series ends are connected to 4 Microwave Oven caps in series each, which is connected to the cores of the other two MOTs, which are separated from each other. But the primaries of the last 2 MOTs are also in parallel with the primaries of the first 2 MOTs. the Secondaries of the last 2 MOTs then have a voltage of around 8600VAC. I measured the multiplying ratios of all 4 MOTs and the voltage will turn out to be 9 x 240.. .which is 8600VAC. So this stack will be capacitively ballasted with the microwave oven caps (C2) and will churn out ~3kVA if all is well.

No updates for a long time. The new school term has been *very very* busy. Today is Hari Raya Haji and we get a 1 day holiday. So I decided not to put off the tesla coil for too long and fix the power supply. As you might have guessed, the diodes blew again. In a fit of frustration, I decided that there will be NO MORE SILICON in the power supply! As such the idea of the 4 MOT Stack was born. (MOT = Microwave Oven Transformer).

I think that the filter chokes are actually doing more harm than good. Some detrimental oscillations could have been created which could have blown the diodes. Today I removed the chokes and tested the coil again. The coil worked for around 2 seconds, and stopped. The microwave oven diodes are hot and they probably died too. I'm not sure if they died because of the removal of the chokes. However, the MO diodes were running with the chokes last night so maybe that might have destroyed the diodes already. I will be getting some resistors (around 50W 100ohm resistors), and get more 1N4007 diodes and see how they perform. I can't do anything with the power supply blown.


Electric arcs can develop inside a microwave.

Last Saturday (7th Aug), I located a good source for the magnet wire. Look at the photo on the left. Notice a small reel of wire, a large reel of wire and a Microwave Oven Transformer. For my , I used 0.2mm wire, bought from RS for $31.10 (about 18USD) per 500g (about 1600m) - quite expensive. I decided to try my luck on yellow pages and search for motor rewind companies. I found a small shop in some industrial area, and they indeed had cheap magnet wire.

I'd seen electrical flames produced by microwave ovens before.

The strength of the e-fieldinside the oven chamber can be described as "high voltage." Once a high-volt electric archas been triggered, it will absorb energy from the microwave field.

If you block up the fan, themicrowave generator will have a meltdown!


Over many months, several people discovered easier ways to trigger the production of these "microwave plasmoids," including using graphite rods from mechanical pencils, or even using a lit cigarette.

Things are different in a microwave oven.

If your microwave oven can put out significantly more than 500 watts, and if you stick a bunch of charred toothpick fragments in the top of a lit candle...

Even more dangerous is to boil water TWICE in a microwave oven.

I only let it run for about 1 second,but this was enough to heat the fluorescent tube so it was too hot totouch.
(Yeah yeah yeah, I know I'm reeeeeally old, and most young whippersnappersnever saw all those ads for the movie "Poltergeist," where the youngdaughter looks at the screen of the misbehaving TV set and says "they're here." )

In the late 1990s, someone on the forummentioned a rumor: that if you in your microwave oven,it will emit large buzzing gouts of plasma which will crawl around on theupper surface inside the oven.

SAFETY WARNING: Treat microwave-boiled water with respect.

Microwaves can be effectively used in the processing of industrial materials under a wide range of conditions. However, microwave processing is complex and multidisciplinary in nature, and a high degree of technical knowledge is needed to determine how, when, and where the technology can be most profitably utilized. This book assesses the potential of microwave technology for industrial applications, reviews the latest equipment and processing methods, and identifies both the gaps in understanding of microwave processing technology and the promising development opportunities that take advantage of this new technology's unique performance characteristics.
