it was morning cruelly woken by my own handiwork my homemade Rochelle salt piezoelectric crystal speaker this is the story of how it all started how you can do it too first thing you'll need is a sound source that outputs to speaker more powerfully amplifier the better all I had was this old clock radio but at least it allowed me to experiment at a minimum you'll need to disconnect the two wires going to the speaker and make them accessible like I'm doing here for the speaker I'll use a piezoelectric crystal this is a rochelle salt crystal that I made these are two igniters that I got from barbeque lighters this one came from a normal hand lighter it doesn't work as well as the other ones anymore but I think that's because I soldered some wires to it and I used too much heat I used like a soldering gun 300 watts of power I have videos as you can see on my channel for both of these showi
