Tealight sounds

I read an article on listening to a LED tealight, that said they use a sound generating chip and that you can listen to them. That sounded like magic, so I wanted to try it.

My tealight unfortunately didn’t seem to have a PCB in it, just an LED and a battery, but I did connect up an amplifier to the LED anyway and listened to my tealight:

Very science fictional sound!

Thanks! I pasted it with the wrong kind of speech marks.

I was disappointed it didn't play Für Elise or anything recognisable as a tune, which ones with PCBs seem to have played, but at least it made a sound and I got that working.

I'm always disappointed by any science fictional sound that isn't the Mysterons or some other specific sound in my memory media catalogue, but I enjoy any general atmospheric "untuned radio" electronic vibe - my analog childhood revisited!
