You've likely seen iFixit's teardowns before. While they are extremely high quality, they usually stop at the point of disassembly. That is probably what most people are after anyway. However, for the EETimes audience, that can sometimes leave you craving more.
Mike Harrison, of the Youtube channel Mikes's Electric Stuff, has released an incredibly in-depth teardown of the Flir E4 thermal imaging camera. Aside from your typical dismanteling, Mike goes on to place the sensor under a microscope and explore it in extreme detail. Literally pouring over the entire surface of the sensor with high-quality video, all the while offering insight and speculation as to what we are seeing. This alone would be truly fascinating but Mike has more up his sleeve.
His next step is to begin to probe the system, analyzing the output from different pieces and sharing his thought process and results. You can watch him decode the i2c output on his scope from an unpopulated ribbon connector on the board. He also discovers a serial port and shares the entire output of the startup sequence.
What is probably the most surprising is that it appears that he gets every single screw back in place at the end of the video. If you're just curious about the unit he's disassembling, he has also done a rather long review of it that doesn't involve surgery.
After doing such stuff myself all the time I had much fun observing somebody else doing it. Funny he missed those screws below the ring around the lens. I found that to be a typical location for such screws on many lenses, historical and new as well. Couldn't determine it from the video, but that "calibration device" might actually be a neutral density filter. At least it would be if this was a visible light camera :-) ... Thanks for doing this video and thanks for pointing it out. This was real fun !
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
