    Lasercut Stretchy Battery Pocket

    Lasercut from stretch conductive lycra, this coin-cell battery pocket makes for a super simple fabric power supply connection. A plus symbol lasercut into the center of the pouch indicates which way around the battery should be inserted.

    Step-by-Step Instructions

    Lasercut design from stretch conductive fabric. On a Zing lasercutter i used the following settings:
    Power: 15
    Speed: 80
    Frequency: 1000

    If the ventilation system on your lasercutter sucks the cut pieces away, you can lay down some masking tape.

    Positive connection (+, plus, 3V): With conductive thread stitch around the edge of the pouch to connect it to a base (non conductive!) fabric. Do not cut the conductive thread after sewing, but continue sewing to bring the power to your circuit. As shown in photo.

    Negative connection (-, minus, GND): Tie three knots in the end of a piece of conductive thread. Stitch the thread through the + hole in the pouch to the back of the non-conductive base fabric and then come back out to the front side of the base fabric beyond the boarder of the battery pouch. As shown in photo. Do not cut the thread but use it to sew the negative power lead to your circuit.

      I’ve looked all over for a good sewable battery holder, but this is the most elegant, cheapest, softest thing I’ve ever seen. Great idea!
