This is a really simple yet enjoying experiment I did with the NE555 programmable oscillator.

I quickly assembled a square wave generator with the NE555, with a low frequency (around 50hz), and I attached the output of this to a single transistor amplifier (NPN BD167), which is used as a source for the Led and the Hard Disk speaker.

Enjoy!
