LEAP#359 HS-088 Effects Chip
Just another audio effects chip. this time a simple dorbell effect. The effect is very similar to - and not any more pleasant! - than the kind of effect you can get with common two-tone 555 circuits.

LEAP#356 PX088A Für Elise Music Chip
Another potted music chip! Figuring them out is half the fun;-)
The PX088A is a simple, nondescript single-tune chip. Found out it plays the main theme from Beethoven’s Für Elise. The recommended configuration turned out to be a battery killer, but I was able to get it working with a few adjustments.
