Oh right @Njord insisted I tell you, fedi, about this button. It's a big orange button (AC remote for scale) that toggles an extension cord's power on/off when pushed
So far so boring right? Well it had been acting up a bit so we opened it up to change the battery and... no battery?
It apparently uses the mechanical force of pushing the button (it requires a bit of a push!) to trigger a piezoelectric charge which is apparently enough to send a wireless signal to the receiver
Neat!

@MichaelPorter @Njord haven't noticed anything no

@MichaelPorter the igniter puts out a lot of RF noise, dunnit?
Back in the good old days you could blast out enough RF to basically picoweld iron filings at a distance, and nobody would stop you. https://en.wikipedia.org/wiki/Coherer

I remember the old television remote controls had several ultrasonic whistles that pushing a button would be picked up in the television's vacuum tube amplifier and activate solenoids to mechanically change channels or rotate the volume knob...

@rotopenguin I've *never* heard of these! Thanks
Interesting to see the wide variety of coherers. -

@LunaDragofelis @eniko @Njord yes, but not the kind of power you need for prosthetics, more like picoampere. There's a lot of extremely fundamental research that would still be needed for the kind of application you're thinking of ^^'

I got light switches like that in my house for nearly ten years. Sometimes you have to push them several times if you haven't used them in a while, probably to get enough piezo charge for a signal.

@sinbad @eniko @Njord
I got fed up with batteries in door bell button and the "bell" and unreliability (433 MHz).
Eventually I found a real wired pushbutton and BingBong inside box, though that used batteries. So I added a transformer to 8V AC at the fuse box, because the bing-bong real solenoid doesn't care about AC or DC. The bulb in the door bell button is across the switch, so in series & glows orange, thus long life.1950s technology, but 100% reliable.
No spying to Amazon.
