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. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
