Do you like crafting or sewing? Do you love LEDs? Well, why not combine your passions with this 'wire-free' LED bracelet!
Here's a quick and relatively easy soft-circuit project we led a workshop on in April 2007. Have a little fun with conductive thread and 'sewing' circuits and make a cool battery-powered LED cuff to wear out and about. It is only powered while you are wearing it because the fastener acts as a switch. No soldering/wiring required!
Many of the techniques shown in this Instructable were inspired by projects and materials links from Leah Buechley's E-Textile and DIY electronics research. Some examples of her work here:DIY page from Leah BuechleyWhat you will need:Sewing Stuff:
- Felt (for lining)
- Fabric (for top - can use felt for this as well)
- Sewing Machine
- Conductive Thread (we buy from LameLifeSaver)
- Small Pliers
- A Metal Fastener - we like conductive velcro from LessEmf.com, but you can also use purse snaps from Michaels craft stores or even regular sew-on metallic snaps (just make sure they are not painted or coated).
- Battery Holder - we love the surface mount coin battery holders from Keystone Electronics (catalog number 1061 holds one CR2032).
- Battery - CR2032 batteries are available at Radioshack (and even Walmart), they are 3 volt and supply enough power for your LEDs without danger of overloading them.
