Introduction: Simple Sewn Circuit
This is a great project to get students started on sewn circuits. I would recommend teaching students about paper circuits first and then move on to this project.
If you are new to sewn circuits or would like a helpful slideshow about sewn circuits see: here
What you will need in addition to the picture above:
1) Regular thread
2) Conductive Thread
3) Sewing Needle
*Note: You can laser cut felt really nice if you have one available.
Step 1: Step 1: Where to Put Your Light?
Choose the location of your LED and mark it with a pen.
Curl the legs of the LED.
Step 2: Step 2: Choose the Location of Your Battery and Map Your Route
Map the route of your positive and negative sewn threads. Note that you will sew in a criss-cross pattern other either side of the battery, ensuring that your threads don't cross and you short circuit.
Step 3: Step 3: Start Sewing!
With conductive thread sew from each red dot, ensuring that you are looping around the end of your LED leg 4-6 times before moving on to the battery pack, where you will cross-hatch each side of your battery connection.
*The battery pack is sewn on with regular thread after the conductive is in place. Remeber to terminate your ends after finishing the "+" and "-" sides of your circuit.
Step 4: Step 4: Sew Around the 'Pretty Felt Picture'
With regular thread sew around the pretty felt picture, sealing in the sewn circuit and leaving a gap for the battery to fit. Hold your battery in place with a paper clip. Cheapest battery pack ever.
