Most of the effort in making a wearable electronics project seems to go into the mechanical sewing of conductive thread and placement of components. This does not leave enough room for exploration, say changing the placement of components or trying out different ones. This seems reminiscent of early rat-nest electronics prototyping before breadboards came along.
The aim of this project is to make a wearable jacket with pop-in connectors that act as a bridge between the clothing and arduino pins. The jacket will essentially be a breakout board for arduino pins on to the body. This way wearables can be prototyped quickly. To further ease the development, the jacket will have wireless connectivity, and power management built-in.
Some projects that can be easily built using this setup are:
- Animated name-tag
- Music synth touch controls and wearable speaker
- Bike turn lights with touch controls
- Posture tracker
- Personal space tracker
- Hands-on multimeter/conductivity tester (I’m most excited about this one!
- Gesture based remote control
The project has evolved over the past two months through the Wearables class at Tandon, NYU (DM-GY 9103-I). It started out as a wearable breadboard, with the aim to allow quick and dirty wearable prototyping. After much design and redesign, I realised that a robust and easy to use solution is not possible. So I altered the idea to be a wearable prototyping platform.
I wanted the jacket itself to be very robust against wear and tear, even with rough use. So I opted against sewing conductive thread. I researched a lot for a suitable conductive material, testing dozens of metal ribbons. I finally settled on steel ribbon from Adafruit. But the ribbon is prohibitively expensive at 25$ per meter. In true ITP fashion, I hit the junk shelf instead and realised that the steel sheathing for display cables is an ideal replacement. I stripped around 10 meters of the stuff and was on my way to fabrication.
*Sez is currently in prototyping phase. I will update with a detailed build log when the prototype is functional. Here are some pretty pictures of the PCBs till then:
I’m looking for collaborators to make projects with Sez. I’d love to hear from you if you’re interested!
