turn signal biking jacket

This tutorial will show you how to build a jacket with turn signals that will let people know where you’re headed when you’re on your bike. We’ll use conductive thread and sewable electronics so your jacket will be soft and wearable and washable when you’re done. Enjoy!

Step 1: supplies

LilyPad Arduino main board, power supply and USB link

.
Get your supplies. You need:

— LilyPad Arduino main board
— FTDI connector
— mini USB cable
— LilyPad power supply
— 16 LilyPad LEDs (note: these aren’t available from SparkFun yet, but will be soon)
— 2 push button switches
— a spool of 4-ply conductive thread
— a digital multimeter with a beeping continuity tester. This is the one I have.
— a garment or a piece of fabric to work on
— a needle or two, a fabric marker or piece of chalk, puffy fabric paint, a bottle of fabric glue, and a ruler
(Available at your local fabric shop or Joann Stores.)
— a pair of scissors
— double sided tape (optional)
— a sewing machine (optional)

disclosure: I designed the LilyPad, so I’ll make some $ if you buy one.
