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. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
