The Additron was an electron tube designed by Dr. Josef Kates, circa 1950, to replace the several individual electron tubes and support components required to perform the function of a single bit digital full adder.
If you are a homeowner then odds are you back out of your driveway at least a few days a week. Driveway accidents happen more often than people think.
PLEASE NOTE THIS IS A RANDOM VIDEO SCRAPED FROM THE INTERNET. (.i.e. not me)
Addatron has built their first two prototypes the Mach Band 1 and the Mach Band 2 (Rev 1 and Rev 2) and I am using them to back out of a blind driveway. What a relief to get a red light indication on my dashboard when a vehicle enters the blind area that I can't see.

The Mach Band 1 is IoT powered.
