Luckily the general setup of the microwave hasn't changed all that much over the years, making the identification and safe removal of parts fairly easy. The front panel of the microwave above was one of the older models with a motor that counts down before turning the micro switch off, though yours may a newer digital display. If you are new to working with microcontrollers, they also work perfectly in Arduino beginner projects. These beginner projects will teach you how to get started. The turntable motor in a microwave is geared to move very slowly from an AC power source. I also found it handy to have a small bowl next to me to store all of the screws. (Source of microwave radiation). You'll see in all of these articles that the victims of 'popcorn cancer' either worked in popcorn factories, or ate copious amounts of microwave popcorn for a prolonged period of time. These transformers have been re-purposed to create many weird, wacky, and sometimes downright dangerous inventions -- everything from homemade electric arcs, to metal melting foundries, to spot and welding machines. You've Been Doxxed: What Is Doxxing and Is It Illegal? Hold it there for a few moments, making sure it is definitely touching both contacts. This unit is already self contained and compact, and can be put to another use as you will see later. If you’re skeptical of this information, at least minimize your use of the device just in case, until you come to a different decision. “Microwaving in plastic is Dangerous because it can cause toxic chemicals (like … The relay we stripped from the microwave specifies a 12v coil, though many relays operate at a lower voltage. Yes, there are risks in taking a part a microwave. Transformer (commonly referred to as MOT). You may see a flash or hear a loud pop when this happens so be prepared! Don't forget to take the bottom panel out to remove the turntable motor! However, few of us consider the fact that this common kitchen appliance is actually a powerful machine, capable of emitting up to two-thousand watts of electricity and heating food to over 200°F.So, should you believe all the news stories telling people how dangerous microwaves are?

There are several fantastic projects you can do with this beast, which we will go over later in this article. What makes microwaves so effective is that the radio waves they emit have the ability to pass through paper, plastic and glass while being absorbed by food.The radio waves used by microwaves, as with any device that uses radio waves, produce a type of radiation. For more information on learning DIY electronics, check out this great resource. You may have an old one that was replaced -- in my case, my neighbors were getting rid of theirs and left it in our stairwell. Another hazard that you might find only if you pull a radio transmitter apart and smash up the RF power devices is Beryllium Oxide. In 1976 Russia even banned the use of microwaves! Microwaves break chemical and molecular bonds, and can literally rip atoms apart, disrupting the basic biochemical structures of life. 1 Answer. The real dangers of microwave cooking are far more mundane, but no less serious. You do not need many tools for this disassembly though with different microwave designs this could vary. If the superheated liquid is disturbed in anyway––for example, if you add power or stir it––it can “erupt” as the steam is suddenly released from within the liquid. In general, it’s not a good idea to use your microwave to boil water, since this increases the chances of superheating.An electric kettle with an automatic shut-off is quicker, easier and safer than a microwave for boiling water.In a nutshell: If you can, boil your water on a stove or with an electric kettle. 1 x Electric heating element (this particular microwave had a grill function). While wearing your gloves and holding the insulated handle, use your screwdriver or pliers to short both contacts of the capacitor. what shoukld i look out for? Is this safe? weland on Mar 1, 2015 … CAUTION: Make sure you're familiar with the dangers of opening a microwave, because there are components inside that may still carry a charge and could hurt, or even kill you. This contains a motor for the timer along with two more micro switches. The cancer causing compounds in the plastic containers and plastic wraps percolate into the food cooked in microwave oven. Simply removing it is safe, but never try to take one apart. Microwaving food or water causes the formation of "radiolytic compounds" — new chemicals created by the tearing apart of molecules. The MOT is heavy, so it is almost always attached to the bottom of the casing by two or four screws. Buy This Course, Nintendo in More Hot Water Over Switch Joy-Con Drift, The high voltage capacitor can give you a lethal shock, The magnetron inside a microwave can contain. You probably think a microwave door handle must be cleaner than the toilet seat in your office. Earlier in the article I mentioned that the MOT was the most valuable part to scavenge from a microwave, and a quick google search will reveal why.
