content: Hi everyone i was on the strange side of youtube again at early hours of the morning and found this crazy video.I will say this Microwaves have good stuff inside like the hv transformer in the non inverter types but then again i am sure you can rewind the inverter types and maybe get a nice high current dc ect, but anyway here is something that is just batshit crazy.I was thinking about writing to this guy but i honestly think there is no point.enjoy.

content: The first video isn't that dangerous. The magnetron looks to be water cooled and he had a shield around it to prevent the microwaves from escaping.The only danger is that beryllium tube cracking and the dust oxidizing. That shit'll ruin your day.Honestly, people are scared of everything that isn't 5V and hooked to an Arduino.Sent from my Smartphone

content: The main problem really is, frequencies up there propagate so damn easily. You can play with 100s of MHz all day long without interfering with too much, as long as you don't hang long wires randomly off the transmitter.The main hazards to bodily health are RF burns (touching the electrode can't be very good..) and heating (the eyes are the primary hazard, not the testes).And for that matter, it's no worse than sitting in front of a bonfire: the IR radiation from that is so intense, you actually feel it (and not just that you feel it, but that it's so intense, you can't even get too close). And staring at a bonfire for too long will give you cataracts!Tim

"but this guy was i guess smart enough to face the microwaves emitter away from him by using a tin can as wave guide. "I will have to check but i am sure the sheet metal they use in a microwave guide is thicker then a tin can".http://www.dailymail.co.uk/news/article-2104988/Mother-accused-murdering-baby-putting-microwave-minutes-face-trial.htmlMicrowave Radiation can kill.

content: Sorry, but no. I've bought it, it's my device, and I should be able to open it for modification or repair. Warning labels are sufficient for 99.99% of the population and Darwin will take care of the rest.

"maybe i should have put this under jokes or something oh well too late".take care and thanks for reading and watching.

content: The problem is they use security screws on everything. pretty much every consumer device I've looked at in the last few years has some sort of nonstandard screwIf they only used it on particularly dangerous stuff, then drivers would be somewhat less available.However I suspect it's mostly manufacturers arse-covering, as they can claim they've made some effort to prevent people messing.

content: The guy at Photonic Induction is a little crazy and I am surprised that his house has not burned down by now. As for the security screws I agree with Mike, they are everywhere! Last week a neighbor had a disk jammed in his Philips DVD player and when I came to open it the case was secured by pentalobe security screws.

content: Quote from: mikeselectricstuff on November 10, 2014, 10:47:31 pmI wonder if someone could use an accurately machined wave-guide and fry an enemy's kidneys from a distance. In practice, I think a high moisture content in the air and the air itself would attenuate the signal too much, plus it would be extremely difficult to make a really accurate wave-guide at 2.45GHz.https://www.facebook.com/NoPutinAtOzG20

content: Quote from: German_EE on November 12, 2014, 09:01:38 amI've only ever seen Philips use Torx screws.It's kind of good for me, I pick up faulty stuff quite often. Usually people haven't fiddled with Philips items because Torx is a rarer screw, most people don't know what to do.

content: VK3DRB, please read the Inverse Square Law againThey investigated the possibility of a microwave death ray in the 1930's and the prize was 100 GBP for anybody who could fry a sheep at a hundred yards. The man doing the work was called Robert Watson Watt, he didn't invent a death ray but he did invent RADAR.
