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 !
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
