content: These idiots show their total ignorance by deciding to create explosions in environments not designed to contain shrapnel. I will not go into detail here but anyone who has seen a test range for blast experiments will know what a correctly designed enclosure looks like. These guys are basically d*ck heads 'playing' with big bangs. Scary stuff. I hope they win a Darwin award without injuring innocents.I've spent time in Russia and that air bag 'ejector seat' was truly horrific. When our Russian friends get drunk, they can do stupid things (just like other nationals but often more dangeous)... the potential acceleration related damage to his brain and internal organs doesn't bear thinking about. A broken neck was also a possibility. Note how 'caring' his colleagues were for the poor dope as he sat barely conscious on the ground. I have seen videos of Russians watching 'friends' die after 'accidents', too drunk to render assistance...sickening.

content: The one with the bloke sitting on an airbag was just stupid.I thought the one with the kids microwaving the airbag was funny but they were stupid for not turning on the microwave remotely.There's nothing wroing with blowing things up as long as it's done safely. I've done destructive testing of composite Kevlar tubes before in my previous job which was safe because the explosions took place inside a chamber with reinforced glass windows.

content: the problem is when they give misleading information. If your going to do it all on you own fair enough go ahead. But showing it to the world is stupid. they claim that their tin foil is protecting them.... I think not so much when it is so easily damaged. There are better ways of using the internets resources than with that shit. Make me wonder what other people are watching when i struggle to watch an EEV blog episode

content: I didn't think magnetrons contained beryllium oxide. I know some RF transistors do but doubt a magnetron does, although I'm not confident enough about this to microwave one.I was shocked at how clueless he is, not knowing what a magnetron or transformer is. There again could it be an act? I heard his friend mention the word magnetron.Before I saw this video, I assumed he had some knowledge about microwaves, know I think he's just an idiot.

content: Quote from: Sionyn on April 10, 2011, 07:46:21 pmSo, they don't even know what the parts are.They have no remote control over the thing so it could "go off" and then blow in their faces or emit radiation when they go back to it.They are too dumb to know that metal reflects back the waves hence the bright light when trying to microwave a solid lump of iron which clearly meant that the microwave self destructed as it microwaved itself with reflected rays. I mean most of us know that you must not put metal into a microwave - well now you know whyGee I only use a microwave to cook and I know more about one than they do......Some experts. Hopefully there are a good few hundred metres of clear space around the "lab" or i hope someone shuts them down

content: Calling the transformer an electromagnet is a greater danger to society than microwaving random stuff.P.S. I put metal pieces in the microwave oven like a fork or a tea spoon, but only with something that will absorb the radiation.

content: I would be surprised to find BeO in any recent consumer product, if lead is restricted, BeO probably requires explicit permission from the president. But Wikipedia lists magnetrons as one of the applications of BeO, so who knows.

content: I think anything with BeO in it would have a warning label - I've seen these on RF amplifiers but not magnetrons.My understanding is BeO is used where an electrically insulated high thermal conductivity is needed for conduction cooling, and so probably not useful for aircooled items unless the air fins need isolation for RF or other reasons.It's pretty safe unless you start making dust by machining it.

content: Quote from: WikipediaThe comma indicates a list to me, it's not a colon or dash, so IMO high-perfomance only refers to microwave devices, not vacuum tubes, magnetrons or lasers. But you may well be right that it's only used in high quality magnetrons; a consumer microwave with BeO would really suprise me.

content: In the UK If a product contains Beryllium it must be clearly marked as such due to the HSE requiremenst for safe servicing and disposal at 'end of life'.In my experience magnetrons such as found in domestic microwave ovens use various colours of ceramic insulator.I used to repair Racal TA1812 HF transmitters with solid state PA modules. The PA transistors were fitted with Beryllium insulators and we had to put warning labels on the modules even then....around 1987. Sintered Berilium is quite safe if handled intelligently but smashing or burning it is not to be recommended

content: I disagree with those of you who are calling these guys idiots. Rather than condemn this kind of thing, we should encourage it. Experiments like this can be done safely if reasonable precautions are taken, and a lot can be learned as a result.I don't know about you younger guys, but when I was a kid, we all had chemistry sets, experimented with home-made fireworks, high voltage electricity, and other things that today's parents would have a stroke if they knew their kids did that kind of thing. None of us died doing this stuff, but we certainly learned a lot that you just can't get by reading books and listening to stories from old-timers.It was this kind of backyard experimentation that led many of us into technical careers that we wouldn't have considered otherwise. Our present society, which shuns perceived "danger" in any form, is stifling this sense of adventure and the result will be fewer people going into technical fields, and the ones that do will be mostly the 9-5 "it's just a job" type.There was an interesting op-ed piece along these lines recently in QST (American ham radio magazine):http://dissonance.nl/dz/kl7aj-oped.txt

content: When I first saw that show, one of the first things that came to mind is if microwaves could be used to ignite fuel in an engine. Especially if it would be able to ignite ultra-lean mixtures that a spark would not reliably ignite. (It would need pulsed power to work in such a short timeframe.) It reminds me of a joke one of my friends made up. (http://www.diyaudio.com/forums/lounge/7181-more-engineering-humor-57.html#post2269166)

I happily played with the mains as a teenager. something many pareant won't like, my dad was confident I was capable. I even made the odd main project like a flashing neon model fire for a model nativity scene run off the mans all at 240V

content: My first thought was "I wonder how they rigged up a remote start for the microwave", because I gave the air bag 5 seconds before it would blow. Looks like I was about right.Bare minimum, remote start and remote AC power feed for the microwave. So I can be in a "safe" location when I start it and pull power on the device immediately after the event.But then again, I'm not a complete moron.
