Today in class, we focused on a more complicated version of a switch that we worked on in the 1st weeks of class. We took 4 (2) pieces of Fabric and laced conductive thread through both pieces, making sure the threads will touch another when they are pressed together. We then put a resistant thread in between the 2 pieces of fabric (completely covering the thread from touching one another). We then checked the connection to make sure there was no beeping and that when you pressed down on the switch, there was a little bit of conductivity on the OM setting.

These were the amount of resistance for the 3 threads we used today.

Copper Thread – 4 ohm @ 1 meter resistive.

Steel Thread –  68.8 ohm @ 1 meter resistive

Conductive Yarn – 69.9 ohm @ 1 meter resistive, however, the conductivity changes easily depending on where the clip is attached to the thread. It must not be completely conductive and laced with some other type of material.

General Conductive Thread – 200 ohm @ 1 meter resistive.

We then focused on making a switch with a battery holder and a sort of ‘dimmer’ control using the fabric switch we made. The harder you pressed on the switch, the brighter the LED light became. Pretty cool .
