the CEO is very humble . it's a genius solution. Though, we shouldn't be talking about IR & FM as "old school" solutions. The best solution is whatever requires the least resources, lasts the longest, while providing the most creativity & utility. That should be the golden rule of engineering. Software engineers especially tend to dwell on overly complex solutions with gps, 5g, sensors, ARM cpus , etc -- and dismiss a mechanical implementation or simple circuit as "primitive" or "old school" / "old fashioned". Remember that every transistor & circuit is a point of failure. A mechanical solution can last 100 years (like my typewriters which still feel brand new). Simple circuits running industrial machines also last 100+ years. Complex ICs are lucky to last a few years, and often have high failure rates in operation. Why does a trashcan or toaster need an IC? This isn't a rant, it's really to highlight this company's amazing work and inspire more engineers to be proud of elegant solutions once again.
