LED throwie is a great project from Graffiti Research Lab.
So, as a contribute to their project, I made a “Granny Throwie”, LED throwie made with crochet.

By using conductive yarn as electrodes, you can create a simple button with crochet. The construction idea is very similar to fabric button.

This sensor is the very first example of something I made with the circular knitting machine.

This workshop references the motivations behind creating Massage me. We wanted a free massage, so we decided to modify an existing scenario for our benefit. Participants are encouraged to consider alternative interaction scenarios concerning console gaming and must think about how different, and possibly soft input methods, [...]

Sew together various soft electronic components to turn your favorite clothing item into a wearable waste of energy!

Great for use in fabric buttons. Used inside the Massage me jackets to make fabric switches, using a hole making tool to make evenly spaced holes, allowing the conductive layers on either side of the foam to make contact.

These super simple fabric buttons are soft, fun to push and can come in handy when building various prototypes. They all share the same ground or plus, depending on what you hook what up to.
