The Zenith Space Command, one of the first wireless television remotes ever to exist.

These were so cool. Didn’t they work by the pitch omitted? When a mechanical lever struck a plate that emitted a tone. The tv then receives the tone and completes the task.

I think it’s a noise in the ultrasound spectrum. Humans can’t hear it

Na it made a click, that’s why we call remotes ‘clickers’

The click was the release of a spring-loaded plunger that pushed air through an ultrasonic whistle. The whistle was what controlled the TV or stereo.

They were essentially an ultrasonic kalimba

Yup. Entirely passively powered - no batteries at all. Pretty ingenious stuff.

TV remotes back then used to be so heavy. As a kid when no one was around I used to lay flat on my back and toss the remote in the air over my head and catch it while I was listening to whatever show was on. The remote was about the same weight as a baseball.

One time I missed the catch and it (very predictably) hit me in the face. When I showed up to school the next day with a black eye, the teacher thought I was being abused. It didn’t help that my story was so stupid…

We took my grandma’s TV when she bought a new one, it was one of these.

Our dog had one of those steel choker chains, and he’d often change the channel or turn the TV on/off by running around jingling it.

As a teenager I accidentally discovered clinking a handful of coins would also do it.

I remember as a kid in the early 80s, we still had a VCR that had a remote with a cord. It was like 3 buttons or something. We also had a Beta machine in the garage for a while from before I was born.

Hehe I still have one for the National NV-300. It used a pair of wires and each button presented a different resistance. Only issue was if you half pressed a button it might think you hit record.
