Musical stylophone

Make your own musical fun with a Retro Stylophone

The 555 timer IC is one of the most under-rated and yet widely-used analog ICs on the market, and quite frankly needs no introduction. Part of the 555's repertoire is that of a signal generator, and thus can be used to make music.

Xaver Schrems does just that with their Stylophone, a nod to 20th-century electronic music-making. They have devised a 555-based circuit along with an analog amplifier, which uses a custom PCB to emulate a typical organ from the era, as shown below:

Different 555 periods are activated with a stylus via the piano key-style pads on the PCB - a demonstration of which is replayed in the following video:

All the required circuitry and notes are provided, so for more information on how to make your stylophone, visit the detailed project page.

And if you're interested in doing this yourself, PMD Way can help you with the parts, such as:
