Teardown Tuesday. Repairing a Yamaha Surround Sound Receiver Dave found while Dumpster Diving. The fix for this fault is HERE: http://www.youtube.com/watch?v=MwvjAtSr5t8 Service Manual: http://elektrotanya.com/yamaha_rx-v557_v457.pdf/download.html Forum Topic: http://www.eevblog.com/forum/blog-specific/eevblog-378-dumpster-diving-teardown-repair EEVblog Main Web Site: http://www.eevblog.com EEVblog Amazon Store: http://astore.amazon.com/eevblogstore-20 Donations: http://www.eevblog.com/donations/ Projects: http://www.eevblog.com/projects/ Electronics Info Wiki: http://www.eevblog.com/wiki/

Bristol University have a neat new "zero power sensing" chip that takes energy harvested signals and switches an open drain output, the UB20M Voltage Detector. But the marketing has gone too far when they demo a TV that supposedly has zero standby power. Dave busts this smoke and mirrors demo. http://www.bristol.ac.uk/engineering/research/em/research/zero-standby-power/ Forum: http://www.eevblog.com/forum/blog/eevblog-971-zero-standby-power-tv-busted!/ Datasheet: http://www.bristol.ac.uk/media-library/sites/engineering/research/eem-group/zero-standby/UB20M_Datasheet_Rev.1.2.pdf EEVblog Main Web Site: http://www.eevblog.com The 2nd EEVblog Channel: http://www.youtube.com/EEVblog2 Support the EEVblog through Patreon! http://www.patreon.com/eevblog EEVblog Amazon Store (Dave gets a cut): http://astore.amazon.com/eevblogstore-20 T-Shirts: http://teespring.com/stores/eevblog

60 minutes of Dave assembling his silent (low noise) Intel i7 3770K video editing computer. If you find that boring, don't watch. NOTE: This is NOT an instructional video! YES, I used WAY too much thermal paste (as shown in the heatsink instructions!), get over it. I cleaned it and fixed it afterwards. YES, I initially put the memory in the wrong sockets. YES, I did not do any cable management, I just wanted to test the thing, get over it. I fixed all those issues, so no more stupid comments please. Also, please DON'T leave uninformed generic comments about needing a high end video card for editing and rendering. You are wrong for my case, read this first: http://www.eevblog.com/2013/04/16/des... Coolermaster Silencio 550 case.

Dave debunks the Solar Roadways project that generated over $2.1M on Indiegogo, as well as almost another million dollars in US government funding. PART 2 HERE: https://www.youtube.com/watch?v=HOZBrHqTJk4 In this video Dave does the solar generation calculations to see if this system is viable from an energy generation viewpoint, and also how much power the LED's might typically consume. What are the losses in a typical practical system like this? Are Solar Freakin Roadways feasible?, or just pie-in-the-sky bullshit? This debunking covers only a couple of the likely dozens of major technical issues with this concept. The main take-away form this video is that these solar roadways panels will never EVER be economically viable, and the solar payback is simply comical. EVen if they can meet ann the ridiculously high demands on a physical roadway. Also, no amount of research will EVER make this a viable idea. You can't just take existing solar technology (which is borderline viable at best of times) and put it in the most hostile physical environment possible, least efficient environment possible, and most costly environment possible and expect it to be viable. It won't be viable, ever.
