Step 1: Prepare Gloves
You will need: an insulated glove, conductive thread, conductive fabric, a battery pack with room for two AAA batteries, three LEDs, some fabric and cotton stuffing. Take the glove and flip it inside out, so that all your stitching will be on the inside. Mark the spots where your knuckles are. this is to mark where the LEDs will be placed. Now make an incision near the base of the glove so that you can fit your hand in between the outer layer and the fleece layer for sewing.
Step 2: Sew in the LEDs
The LEDs will be placed in between the glove layers so they are not visible from the outside of when the glove is inverted back to normal. stitch the LED in place just below the mark made earlier facing away from the fleece layer.
Start stitching up and around to the next knuckle. Remember that one string is positive and one is negative so be sure not to let these cross over each other.
Step 3: Attaching Battery
Step 4: Construct Pressure Switch
Next construct the other side of the switch. Start by attaching the negative thread coming from the battery pack to the piece of conductive fabric. Next make a hole in a piece of regular fabric and start sewing it to the conductive fabric to it using regular thread ensuring that there is a thin layer of cotton in between the layers. This bit of cotton is important because it keeps the conductive fabric from touching the conductive thread until pressure is applied.
Step 5: Fasten Switch Into Place and Enjoy!
The final step will be to stitch up the holes in at the base of the glove. It is also a good idea to stitch a piece of fabric over the areas where the conductive thread is showing so that it is not directly touching your skin when the glove is flipped back around. Finally invert the glove so the outside in in again.
The final product will look like a normal glove because all the stitching and components will be hidden. The lights will illuminate when you grab the handlebars of your bike!
