Microwave Oven Parts Uses

[FRC]

I would like to hear from members about microwave oven parts uses. I have not taken one apart yet myself, but would like to know what to look for and how these parts can be used in projects. Any information would be greatly appreciated.

Anyone do this ?

Hi All,
Could things really be this easy with a microwave hack on a lawn mower engine? I quote showing the source from Gene Mallove circa 1995. Maybe it has been discussed before and I missed it?

"Someone sent me a hard copy of this and I transcribed it. May make for some
fun experiments connected with cavitation, steam, and O-U.

I am posting the following for a friend who does NOT have access to Internet.
Comments welcomed.

NOTICE

The prupose of this notice is to place into public domain something which I
invented so that it may be patented and in order to prevent it's use from
being restricted in any way.

The device is an engine in which small quantitites of water are turned into
steam by the use of a magnetron (as found in microwave ovens).

Interested parties may wish to try this test: Place a few drops of water into
a clear plastic 35mm film roll holder and put the cap on the film roll holder.
Place in a microwave oven and turn the oven on. The 'pop' is the result of
the water turning suddenly into steam.

The engine I have invented is far more efficient than any other steam engine
because the efficiency of the magnetron in turning water into steam. In fact,
the water droplet 'explodes' very much like air/gasoline explodes in a
conventional internal combustion engine.

This engine was first tested in 1992. I am however unable to invest the
required capital to produce a more sophisticated model and therefore unable to
patent it. Even though I may not be able to profit from this technology, it
is too good to be kept to myself and I would like to spread it around so that
others may be able to use it.

The following is an outline of how to construct the device and a few cautions:

PARTS NEEDED:

1. Magnetron from medium power microwave oven.

2. Small 4-stroke single cylinder lawn mover engine or similar engine with
'old style' points and ignition system.

3. Automotive alternator with built-in rectifier and regulator, also a 12
volt auto battery.

4. "Trigger" mechanism from an aircraft "strobe" landing light.

INSTRUCTIONS:

1. The magnetron fits into the spark plug hole.

2. The distributor points are modified so that the contact is closed when the
piston is at the top dead center and this contact is used to activate the
aircraft strobe mechanism.

3. The high voltage from the strobe is connected to directly fire the
magnetron which in turn produces steam which moves the piston.

4. The engine turns the alternator which keeps the battery charged, which
supplies the electrical power for the magnetron.

CAUTION AND TIPS:

WARNING!!! DANGER!!!!

1. Be careful around the magnetron. KEEP IT SHIELDED WITH METAL. IT CAN CAUSE
SEVERE BURNS THAT MAY NOT BE READILY VISIBLE WHEN THEY FIRST OCCUR.

2. The 'strobe' trigger delivers a very high voltage which can jump to ground.
WEAR RUBBER SOLED SHOES AND INSULATE WELL.

3. Be sure to modify the distributor points so they close at the top dead
center. Timing advance depends on the power of the magnetron used and the
amount of water. Try different carb jet sizes -- drill out if needed.

4. Due to variables, don't expect high engine speeds without a little
experimentation due to variables.

5. Start with a fully charged battery or your alternator won't work.

6. The energy produced is in excess of the power required to run the
alternator but until you get the RPM up, and the parts wrking in harmony, it
may be best to use a battery charger instead of an alternator.

7. An easy way to measure net power output after you have the alternator on
line is to run a few 12 volt lights from the battery. You will see that the
battery stays charged even with the lights on and the motor keeps on going.

8. Although I have not tried it, the idea of vaporizing water with microwaves
should also work well in a converted turbine.

I think the above concept could also be done with this. One could use a 1500 watt inverter to power the microwave and a reed switch or mechanical points
instead of the strobe. Or some other commutator arrangement.

have to say that video caught my attention, utilizing steam like this could be promising. i also love how he gets shocked with the reed relay off of the solenoid back spike, somehow tapping that might make for good charge recycling. Also on the magneto, if you were to use a reed relay switch you could use it in a flyback fashion to were it shorts out the coil using the magnet as a trigger, this prevents the engine from just plainly running an induction load and adding resistance, instead triggering the short when the magnet is there, and of course somehow recycling that energy.

as for the microwave you got me beat- i picked up a "broken" one from the dump (only one fuse was blown so kudos to the idiot who threw it out). it leaves me with a self discharging capacitor, a dangerous microwave transformer, a very nice ac fan, and a series of mechanical and relay switches... oh and an incandescent light... lucky me

[FRC]

Thanks Ricks

Thanks Ricksl that's exactly the type of info I was looking for. I did not know
that they had relays and caps that were self discharging.

FRC

[ricksl]

well ive seen other people find good ones that don't self discharge, but it seems like the few ive taken apart- carousel- have Samsung made capacitors that are rated at ummm... i have no clue the voltage but i know it is .94uF, and it has a built in 10meg ohm parallel resistance as a safety feature, really kinda limits its use because whatever you use it on has to have it operate on a frequency that can avoid this self discharge curve. Was also upset at the fan i wanted to replicate lidmotors light multiplier but the coil was not center tapped like it needed to be, just ac induction motor coil.

So basically if your looking for either of those things avoid carousel, just out of curiosity what were you thinking about using these parts for?

Could always use more caps. Don't really know of anything specificaly, I was
hoping I could get some ideas on what to use them for by starting this thread.
I have one I can take apart right now. I could have got quite a few over the years, and will start collecting them if it is worth it.

I've got one microwave fan coil that was bifilar 3 pole.....little mod added a fourth pole and have basically a bedini coil....it works, sort of premade, neat.

other fan coils from micros that are not wound this way have still been of some use.

couple big ring magnets

caps....i think mine are 2600....could be wrong

Post #2

I had an old Popular Mechanics, or Mechanics Illustrated, or one of those and
it had a story about a steam car using a converted marine engine. My concept,
after seeing that was for a hybrid version. The steam would power a generator
for electricity, a microvave oven would heat water to generate the steam. The
vehicle could be either electric or steam driven, and there might be less input
of fuel needed. You would have to experiment with different combinations to see what would have the best efficiencies.

Above Is a post I did on a previous thread.
Post #2 of this thread would work better I think.

Very interesting

+ 1 to resourcefulness.

I know you can use the MOT for a lot of different things. (as I've recently been reminded ) If you have access to a HHO torch, or a torch used to otherwise cut steel or thick metals, you can scrap the coils inside the MOT.

(Personally, I think I can make an HHO torch easily, by tweaking the setup of the fuel-producing chamber -- from the HHO engine thread)

The caps are very high voltage, lots of electrical pressure contained in there. I know I can use the caps in a spark plug circut -- I was thinking about using two Microwaves or so, to scrap most of the parts I'd need for a gray tube.

The magnets inside are circular, I use those on something like a trash can lid to examine the waveform over coils when I move it over the coils. I use the trash can as a wheel, and stick the magnets on the outside, a-la-bedini.

I usually scrap lots of things from circut-boards I see all over the place. This is where I get most of my Zamak from --(Not microwaves) -- from transistor fins, and metal-cooling housings. I have a few big boxes of random electrical gear, that is now beginning to come in handy.

I know that from these kinds of parts, you can make lots of different things if you are creative. I am currently, for instance, trying to build an air capicitor, so as to "tune" the ionizer circut / resonance of crystal oscilator easier (from the HHO thread).

This is an alternative to having the EXACT cap. size, or constantly switching out caps for bigger/smaller ones constantly.

For instance -- I am using some metal from an old audio amp housing, cutting it into little peices and sticking them together to make the air cap. I would assume, if I could find another microwave, I'd use the housing for the same purpose (make another Air cap.)

While these little suckers can be tricky to figure out what voltage/capicitance that you have made, the "tuning" that you can do with these is easily worth the hassle.

I don't know if you're very into "saving" the old copper wires, or the old metal chunks and melting them down -- I plan on making ingots from the metals in the near future, so that I might be able to "saw" out the metals with a thin blade, into an air capacitor easier.

I like to see that other people are looking for uses of stuff that's been laying around. Hope this gives you some ideas.

Peace,

Thanks Romo

Thanks Romo for the valuable information. Sources of useful parts do not have
to be limited to microwave ovens. If someone has other ideas, feel free to post them here.
