My mother used to work in a doctor's office with a British woman, a WWII "war bride". She always had one handy. It was the first that I had seen a Round Tuitt. That was in the 1970s. The "Jinx Remover Spray" is getting a little old at this point too. It's been a common gift shop item for a long time.
I've often thought that there might be some off-label use for "Anti Monkey Butt Powder" (a legitimate product).
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.
