- Introduction -


Making music is one of the great human pleasures. Designing and building musical instruments has been a noble human activity since before recorded history, and there's always someone trying to make a better one. In any age the best technology available has been applied to music making. Fine wood working for violins, brass forming for trumpets and horns, and then complicated mechanical systems for pianos and organs. In our era, electronics has been pressed into the service of music making. The 555 timer chip can be a starting point for building a "musical" instrument. Build a "synthesizer" as this Core Project.


Performance Criteria

The design presented here has been tested and it works. There are many ways to control the frequency which a 555 timer chip produces. Can you improve the design?
