Miniature oven

Please don't laugh but I am building a small working oven for my daughter and need a heating element that can heat it from 70 to 220 degrees celsius via a thermostat. I've found this heating element or and this thermostat but am not sure these are suitable and would work together. The oven will measure about 15cm wide x 8cm hit x 10cm deep but I don't have to stick to this.Any help or advice would be amazing. You're laughing aren't you? :)

Powering oven resistor Answered

Hey :)Does anyone know how to power an oven resistor ? Is it really a simple resistor (I'm not sure as it is directly exposed in oven, it seems too dangerous for the user if it is simply a metal stick) ? If I plug it to 220V sine 50Hz will it heat ? Thanks :)

Solar oven theory

When looking at various solar oven on instructables, they almost all use refective coating of some sort on the inside. That to me makes sense for the concentrators/parabolic/funnel ovens, etc. I am just wondering if the regular box ovens if it really makes as much difference or if the heating factor there is more so just the still air in the box being heated and not able to escape. I want to start making solar ovens to get an idea of how they work. I have a square piece of 1/4 inch glass, probably 4 ft by 3 ft. I thought about just digging a cubic hole in the ground and laying the glass over top.

Checking electric on an oven

I have a problem with my oven which is tripping the fuses. It has a grill, top and bottom heating. I have diconnected each of the elements and think I have isolated it to one of the elements. I have removed that element and find, I can get a continuity reading across the two in put terminals, which I guess just means it is intact. However, I get a low reading across the earth and one terminal. Can anyone tell me if that is what I should expect? It's so annoying as I have had the oven almost 5 years (new with the new apartment) and this is the first time I have tried to use it. Previously I just used my combi microwave. Thanks for any advice.

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.

USB heater

Hi everybody! As sais in the title of the topic, I want to realize a USB heater. Let me introduce you to what I think. Last week, I was in the store near high school with some friends, and one of them told me : "It would be cool if we could heat up things in high school, to have like a mini oven directly in our locker, working with battery." Of course, the idea is not to install a oven in our locker, firstly because it would need an incredible battery, and secondly because it would be pretty dangerous.... So here is the idea : the goal is to heat up at least 2 chocolate breads at 60°C. The heating time is not very important, but it has to be under 40 minutes (a system will start the oven before our break). But here is not the most complicated : the oven has to get its power from a usb power bank(I can plug in 2 power banks if necessary). To conclude, I have to fin a solution to heat approximately 1.5L,( but most of it is filled with air), at 60°C, with a power of a maximum of 20W. I saw things to heat coffee by USB, would it work if I take the heating pad? Also, I would like to know how much power I can  get from a power bank (in W), before it to heat too much.

Microwave stopped heating and I fixed it.

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.
