The 555 Timer IC

The simple but powerful 555 timer IC can be rigged to produce a timed pulse or a square-waveform oscillation up to 68kHz. It later came in dual-timer (556), quad-timer (558), military-grade (SE555), and low-power (7555) configurations. Although it's largely obsolete in commercial electronics, it became beloved of amateurs wanting an easy and cheap way to make things buzz or blink. In memory of the recent passing of its inventor, Hans Camenzind, Make Magazine offers a retrospective of 555 contest winners. Here's a tutorial on chip function from instructables. How to build a toy piano. The morse code practice circuit. Miniature beeping circuit prank to baffle your friends and co-workers and a screaming altoids tin.
