The Turn Signal Hoodie project is a simple circuit sewn by hand into ordinary clothing to make something useful and fun. For about $15 in materials you can add switches and lights to your clothes that add to your visibility when riding a bike in the dark, or get creative with the placement and have them just for fun.

The only skills needed are the ability to thread a needle and make stitches with it, and the ability to tie a knot in thread.

This tutorial will teach you what you need to know about the circuit and its components. You can do this!

Materials:

  • Hoodie or sweatshirt
  • At least five yards of conductive thread
  • 10 LED’s of an appropriate type (see appendix)
  • A scrap of thick fabric to make two “soft switches”
  • Two sewable 2032 coin cell battery holders
  • Two 2032 coin cell batteries

Necessary Tools:

  • A pair of needle nose or jewelry pliers to shape the LED’s and coin cell holder leads
  • chalk or other washable fabric marker
  • Scissors for clipping thread
  • Two needles sized for the thread
  • Seam ripper- just in case!

Recommended Tools:

  • Multimeter
  • LED tester
  • “Fray Check” or super glue to keep thread from fraying
  • Fabric tape to glue switches to cuffs
  • Needle threader
  • Hole punch to make a hole in the soft switch
  • Safety pins to mark locations of LED’s

Notes:

Throughout the pattern I’ll be defining sewing vocabulary terms. All of these definitions are also included at the end of the tutorial in the “Lexicon” section.
