How can you quiet vibration on side panel where magnatron is located, if I put my hand on this location you can feel it vibrate and by applying a little pressure the noise is cut in half , tried square piece of rubber used as seam tape for rubber roofing helped a little but looks ugly (wife)

I have that maker-ish compulsion to disassemble any and every broken or otherwise defunct appliance, gadget or device. For example, my microwave just "went to sing with the choir invisible", so I have begun turning it into a pile of parts. I got to thinking- as many of you must have doe before- "what can I do with this stuff?". Just like anagramists take words and shuffle their parts (i.e., letters) around to make something(s) new, different and/or clever, I'd like to try to do the same thing with my old appliance. But more generally, I wish there were a database of appliance "anagrams"- a list of clever projects classified according to the appliance from which the parts come. Anyway- if anyone has an idea what could be done with an old microwave (I've got my eye on that big capacitor...), please hold forth!

I have salvaged a old microwave transformer that i am going to use for a SLA battery charger i am building. I have rewound the secondary with 50amp wire and i get an AC output of 12v what is what i want but im confused with working out how many amps it puts out. I have run it through a bridge rectifier and a capacitor and i get about 18V DC. I was testing the amps by adding 12v 50watt light bulbs to it 1 at a time and when i get to 200watts the voltage starts to drop to about 10v DC. My question is does that mean the transformer is being overloaded? and if so is there a way to increase the amp output by winding secondary with different wire? I have seen online videos of Microwave transformers being rewound and they give out 50amps at 12v.

I was wondering if anyone could help me figure out the proper way to connect a 5V battery power source to this microwave timer (pictured) I read this post- specifically the comments, but am worried I might fry the board if I do it wrong and with a 50/50 shot I'd like to ask the experts first. I've provided pictures below. Thanks for any help you can offer.https://www.instructables.com/id/Digital-timer-for-any-electrical-appliance/?ALLSTEPS

I recently got a working microwave transformer for free, it has unknown wattage, though. What's the best way to ballast it? Some people use lightbulbs, I'd rather not use lightbulbs cause that's almost as dangerous as the lightbulb it's self (I'm comfortable with the transformer, I'm not comfortable with a 500 watt lightbulb, ironic?) No saftey speeches, please, lol.

Our microwave is about two years old and it stopped heating. The fan ran and the carousel went around, but food did not warm. I took it out of the upper cabinet mount and opened the case. I know about the big capacitor and discharged it with a screwdriver after disconnecting the power. For extra safety I clipped a jumper wire on both terminals. I watched numerous videos at YouTube on troubleshooting a microwave and on testing the various major components at home, but no component showed any signs of failure. Then it began to work again as suddenly as it had stopped working. About ten days later, it stopped heating again. After more testing, still no components showed signs of failure. But, I did squeeze the female spade crimp connectors a little with a pair of pliers before connecting them again so they fit more tightly when reconnected. The microwave has continued to work as it should. My wife remembers a time a few months ago when she ran it and ran it to get something to cook as she wanted it and the microwave stopped because it was overheated. I suspect a connection was weak and heated the metal in the connector enough that it became weak. Later it failed intermittently. We could have called warranty service, but we did not want to wait. Knowing what I know now, I doubt a serviceman would have patiently checked for weak connections, but would probably have simply replaced some parts. When those did not really solve the problem, the microwave would have been condemned and replaced. A replacement oven may not have matched our other appliances as well as our present microwave does. Test procedures for components in a microwave are different than they are for similar components used in (for example) a sound amplifier. This applies especially to the high voltsge diode. Do not connect a voltmeter to the high voltage side of the transformer. When running the microwave, be certain to have a dummy load in the cavity, like a cup of water. A very useful test that checks for power to the transormer primary is to disconnect the primary side transformer connectors and attach aligator clips from a voltmeter to the transformer leads. Then run the microwave for a few seconds and check for a full line voltage reading each time. A clamping ammeter to measure line current helps because the sound with the magnetron working is not too much differnt from the fan and carousel running without the magnetron working, but, it is easy to see the extra needle deflection when the magnetron is also drawing current.What seemed to be an expensive problem had an easy inexpensive solution.

Hi so I was bored and decided to make an electromagnet out of a microwave transformer by taking the secondary off and keeping the primary. I hooked it up to some 9v batteries and stuff but it wasn't that strong so I researched it a bit and found out you can hook it up to the transformer input voltage (which was 240v AC) so I did but when I turned it on it made this very loud buzzing noise and I thought I saw what looked like flame in the socket. I turned it off imediately and unplugged everything. Whatever the magnet did must of been strong because it broke itself apart slightly. I tested the sockets with a multimeter and they still say 240v but I just want to make sure I didn't do anything bad to it. Also did anything actually go wrong or was this all meant to happen?

Hello, my question is simple. If I connect about 3v to a microwave transformer and then to a coil, would it make a efficient EMP wave (shutoff a calculator). I know that I can use a disposable camera, I just am learning different ways to do it. (Sorry for the pic, done with my phone haha)

I am taking apart an old microwave and trying to use the turntable motor inside of it for another project, but I dont really know even how to power the thing once I get it out of the microwave. Does anyone have any ideas as to how I would do this. Also, I have a limited budget/limited knowledge of this type of stuff. I just need a motor that has decent torque and low rpms so I think this motor should work well.

How long can a microwave retain an electric charge? I think I need to change a fuse as the unit completely stopped working when I reset a fuse for the kitchen when I found our refrigerator had stopped running. I confirmed that it was indeed the microwave and not the electrical outlet that wasn't working. This occurred 3 days ago. The unit is still plugged in - how long would I need to have it unplugged before I could safely remove the back cover to get to the diagram or the main fuse to see if it's burned out? Thanks for any advice on how to do this, we can't afford to buy a new unit and it sounds like buying a new one would be cheaper (or cost the same!) as hiring a repairman.

So I saw this post here and I too am feeling creative and wanting to make a portable HERF gun powerful enough to make a ripe piece of fruit explode within less than 1 second. So here's some ideas about how this thing works: 1. The device would use a an appropriately sized vacuum magnetron with an electromagnet The current fed to the magnetron's electromagnet would be a rectified sine wave at the resonant frequency(oscillating current flowing in but not out of the electromagnets coils). The purpose of this technique is to use resonance to turn the magnetron into an amplifier as well as an oscillator so it functions as a maser of sorts(not sure if this has ever been done before). 2. This thing is going to need a lot of power, and I have a solution: pneumatic electricty. The electricity would be produced by means of a high speed electric motor with permanent magnets(which can act as a generator)that is capable of spining several hundred RPM without frying itself. This genemotor would be driven by a turbine spun by by outflow from a cylinder containing compressed air. When the trigger is pulled, the cylinder valve opens and the air is released into a small turbine chamber and then expelled out an exhaust tube extending out the back of the gun. My 1st choice of material for the gas canister is titanium since it has to be both compact and capable of storing compressed air at up to 1000psi(or above). But the big unknowns are a)how much power will be needed to suplly the magnetron and the RF oscillator/rectifier, b) how fast the generator will need to rotate to produce that power ,c) how much pressure is necessary in the compressed air canister, and d)what material I will need the canister to be made of. Any suggestions? Thoughts? Comments?

I just discovered that the inside of my microwave has two rust spots in it. It's also seems to have air leaking from it when it runs, or at least I can feel heat. My question is, since I know little about microwaves other than usuing them, is this microwave still safe to use? (My guess it isn't, but thought I'd ask) It's an older one given to me by my cousin. Thanks.

This is my Microwave Oven Transformer stack. It is currently current limited using a heater. There is approximately 10 36 watt 4' fluorescent tubes in a string around my garage that I am lighting with the MOT stack .My MOT stack contains 4 Microwave Oven Transformers connected with their outputs in series and their inputs in parallel. They are mounted on plastic cutting boards. I am using threaded rod to hold the layers in place while the PVC pipe covers the threaded rod and it also supports some of the weight. The output of this is approximately 8800VAC at 350mA The Input voltage is 240VAC Thanks for looking, Please comment and remember to rate if you like it! Just say if you want any pics of a certain thing, e.g. the MOT stack arcing to wood/metal etc. (I will try to get more pics of it arcing soon but it is hard to use a camera that has like a second delay before it takes the actual pic from when you press the button, stupid camera) ********************************************************************************************************** Edit The new pictures are of an arc between two carbon electrodes.

I was looking around and was hoping to find somewhere a guide to make a portable microwave, I have looked around on the internet for hours trying to find a DIY one because I want to make it myself rather than buying one. What I am trying to do is find a way to make a microwave portable. I wouldn't be making the actual microwave though, I would just buy one that you guys would hopefully suggest for me to buy. The purpose of this is to have a microwave that I can put inside of a locker for cooking food in. I just need someone to guide me through because all I learned through my searching was that I possibly needed an inverter, due to it being battery powered (I assume.) Then again aren't there car batteries that can run on AC like a microwave, although I am not sure which is why I am here. Summary: What I am asking is someone to make a step by step tutorial or guide of some sort to making a microwave portable (not building the actual microwave though, just making one portable to be runnable by like a car battery)
