Everything old is new again, I suppose.

I was going to mention the “Space Command” as well. It basically has three spring-loaded hammers that are latched and released to strike metal rods sized to generate specific ultrasonic frequencies when hit. Pretty much like a tuning fork. It worked great, and… no batteries!

first battery-less? nah, look up “Zenith Space Command”.
it had a remote control that worked on sonic sounds or something. basically it was a “real” clicker.
