Good video, very clear and useful info. It reminds me of the time I used to dismantle tv, fridges, hair dryers, toasters, radios, car engines and water pumps etc. It was useful to see how things worked and the parts were useful afterwards, but then 'simple' people would ask me why I'm collecting 'rubbish'!!!! They clearly had no vision or foresight, as I learned a lot then went to uni and am now an engineering designer and MD of two engineering companies! Anyway, keep up the inspiring video work

Correct. Most of the microwave caps however have so-called "bleeder" resistors internally (this one also did): They're designed to slowly discharge the cap when it's disconnected. Typical bleeder value is 10 MOhm. With a cap value of 1uF and an assumed initial charge of 2kV, this means that after 30 secs there's about 100 Volts left and after 50 secs it's down to 14V. Therefore no cap. Bleeders aren't a guarantee, though, so better be safe than sorry (it can hurt quite a bit).
@TubeNotMe6 жыл бұрын
I would have shorted that cap before taking the fan out or anything like that, just to be sure. Just use a metal tool with an insulated handle to connect the leads. I appreciate the speeding through the boring parts like removing screws.
@johndoe27182812 жыл бұрын
I see where you're coming from, and agree. Beryllium oxide is a pretty hard material and if you dismantle the magnetron carefully, you'll definitely be fine. That said, however, in the video I really wanted to stress that you have to know what you're doing -- and if you don't, you should better leave it alone.

Hmm, probably not without reasonable effort. The filament is inside the resonance chamber, which will usually be welded shut. So you'd have to cut that open first. Why are you particularly interested in the filament, if I may ask?

Help! The door of my microwave suddenly will not open. I put in a cup of tea to heat it, and now the door won't open. When I push the door opener button, it seems to press down much further than before. How do I get at the door to release it, remove the cup of tea, and begin fixing the faulty door latch?

So I am honestly scared of the capacitor , right now especially one so strong lol , i see the magnetron as profit , The transformer is in working condition. Everything works except for the start button lol anyways I think I’m just gonna throw all those good parts out as they are of no use to me as of now and the risk seems a bit high for my liking.. The fan however.. What would I use to power it? It’s 17W 120V

You're better off removing the capacitor. It's not only safer but it will give you more internal room to work with when you do your conversion. Hope it turned out very well.

@836dmar11 ай бұрын
In addition radiation is dangerous based on cumulative exposure. I can’t understand the alarmist attitude about the pink berillium or asbestos either. Yes, know the danger, but if I walk by and breath asbestos one time I’m not likely to immediately double over with lung cancer. It’s a correlative risk but is not an positive causation of illness.

Kein Problem: Beim Zerlegen des Magnetrons muss man ein bischen vorsichtig sein. Manchmal sind dort Keramikisolatoren verbaut, die pinkfarben sind. Die bestehen aus Berylliumoxid, das sehr schädlich für die Lunge ist. Insbesondere der Staub ist gefährlich (ähnliche Wirkung wie Asbest). Deswegen auf KEINEN Fall zersägen oder zersplittern und am Besten das Zerlegen des Magnetrons meiden, wenn die Isolatoren aus Ber.Ox. bestehen. Und eben die Kondensatoren korrekt entladen. Viel Spaß beim Basteln!

@TubeNotMe6 жыл бұрын
If you slip while trying to remove the housing and crack that insulator, a small amount will be dispersed as powder and tiny particles. You don't want to get any beryllium in your lungs at all, so he's recommending that you don't take the chance. I've seen another guy take one of those apart but he also said he would not recommend other try it.
