I guess you could call this a hardware hack. When I was just out of college, there were over-the-air subscription TV channels. Every electronics company in the boston area has a schematic for a channel 68 decoder. the were based on either and LM1800 or LM1310 stereo decoder. I even made a PCB as I had worked in a PCB factory in HS and college.
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.
