20 kV Diode Teardown [video]
- pininja 5y agoI’m surprised he still has fingerprints after all that sanding - impressive!
- random3 5y agoI also noticed he doesn't use gloves :)
- Salgat 5y agoThis video seems a bit lacking in information. Very cool to see the actual innards of the diode, but it feels like a quick picture and 2 sentence description could cover the same amount of information.
- dmitrygr 5y agoBut then how would you be served 3-10 ads?
- brentcetinich 5y agoYT premium FTW
- martyvis 5y agoI'm amazed when people mention getting interstitial ads on YouTube (or I even get confused sometimes when following a link from a website that launched YouTube, but doesn't register my ID). Happy 4+ year YT premium (formerly Google Play Music ) subscriber here.
- tsimionescu 5y agoA good ad blocker is even better. It would be awesome if it could also auto-skip in-video ads. Best part is that ad blockers work all over the world, not just in the few corners where YT designs to let you pay to skip ads.
- sjruckle 5y agoTry the SponsorBlock addon. Nobody's added anything for this video, but there are a lot of other videos that have their ads in its database.
- Something1234 5y agoNot sure I agree. The extra time and listening to him gave me some ideas on how the parts are used, and made. He talked about the materials and explained it in different ways. It's awesome to see what people are interested in.
- pininja 5y agoThis video also includes a look at cross-sections of resistors, inductors, capacitors, and standard diodes too!
- c54 5y agoReally neat, thanks for posting. Good example of cracking open the literal black box of these various electronics components to see what's inside
- fnord77 5y agoa transparent belt-sander would be handy
- Arainach 5y agoFun video, but one note: You should always use sandpaper as if someone else is paying for it. It gums up faster than you think, and if your "250 grit" sandpaper is full of tiny particles that wore off and is now acting more like 1000 grit, it just means more wasted hours for you. It's fairly cheap stuff, so don't forget to change it often - certainly more often than seen in this video. This is particularly important at the initial state where you're eroding down to a level - when you're just going through grits smoothing it matters somewhat less.
- superasn 5y agoAnother fun video I found today showing up in related videos for this: https://youtu.be/WtExoSMgvXI?t=260 https://youtu.be/WtExoSMgvXI?t=260 These guys are sanding down the mobile CPUs and soldering jumpers to do a password reset. I didn't know this was even possible.
- marcan_42 5y agoIt's just accessing the onboard flash memory. Sometimes the easiest way in to a given pin is through the top of the CPU package (obviously they are not hitting any actual silicon), if all the traces are otherwise buried in the board.
- emj 5y agoKamikaze hack on XBox, was sold as a template for drilling a bondwire on a SoC. This is without the tempalte: https://www.youtube.com/watch?v=1gCYXb54oig https://www.youtube.com/watch?v=1gCYXb54oig
- superasn 5y agoThis is insane. How do they even figure such things out? Is it by accident or careful research of schematics?
- wiz21c 5y agoDoes gritting with super fine sandpaper like he does can produce toxic dusts (inhalable) when working with electronic parts made of various materials...) ?
- mmazing 5y agoHe would have great luck with a bench top belt sander with 250 grit, and sticking to the higher grits by hand for final polishing. Much easier when you can let a power tool do most of the work.
