Ha! The dude got rich off what seems to be a 555 timer! I think he got the schematic out of a Forrest Mims notebook.
I like the extensive testing they did those days. The dude wires up a 555 in a metal box and the next day they hook it up to a girl in the hospital.
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.
