Final Project: Stitch Synth#

Stitch Synth is an e-textile, modular, analog synthesizer. Which is a complicated way of saying it’s a collection of electronic circuits that make sound, where hard circuit boards are replaced with fabrics, and wires and resistors replaced with conductive threads and fabrics.

A research project on e-textile circuits and soft interfaces for making noise with electronics, Stitch Synth is motivated by the hidden history of women in electronics (and electronic music, and more) and the potential for e-textiles to develope new ways of making electronic circuits, and new ways to interact with them.




Playing Stitch Synth is easy! Snap the modules together, plug it into a speaker, and touch / press / pull the sensors to make different sounds.

Go to the PLAY page for more information on how to play Stitch Synth.


Stitch Synth is an analog synthesizer. With no computers, no coding, not even a microcontroller, all the sounds are generated by logic chips (aka CMOS ICs) working in combination with capacitors and resistors.

The LEARN page has more detail about how Stitch Synth actually works, including circuit diagrams, an explanation of logic gates, and an introduction to e-textiles.

Big influences for Stitch Synth were Handmade Electronic Music by Nicolas Collins, and the Logic Noise on Hackaday. I highly recommend these if you want to get into making your own analog synths!


You can make your own Stitch Synth! Depending on what materials you can get your hands on, you can make some or all of the modules.

For detailed instructions go to the MAKE page.


There are lots of ways to add, change, adapt Stitch Synth. The HACK page gives you some ideas on where to go from here, and tips on developing e-textile projects.

To be added: - information about design (squares because zero wate) - something about expressiveness of sensors compared to traditional instruments
