If your into making weird noises and also like to mess with a soldering iron maybe you should give circuit bending a try. That’s where you poke and prod around the electronics of a device (like a Speak-n-spell) and cause the output sounds to be changed in weird ways.
I think I did this by accident when I was a very small child, my father had and electronic piano that would pick up radio stations if you touched some components on the back. Me and my friends thought that is was pretty cool at the time, but then again we were about six.
…examples of game cartridges and portable systems that have been circuit bent to create a nice glitch aesthetic & sound…Jumpstart has been bending the Gauntlet game on Sega Master System II here.
