Yes, those tempus fugit coils are a pain to balance. If the clockwise and counterclockwise coils are not in perfect balance then the time machine tends to drift off into the future or past, which makes it really hard to keep parked.
There's a term for that imbalance, btw. It's "the tempus fidgets."
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.
