Step 6: Minutes 11-60: Testing and troubleshooting
Here are some debugging tips to help.
First rule of embedded electronics: test the simplest case first.
- before attaching any thread/wires, first plug in the dock connector
- use a paper clip (or tweezers) to connect the two large sewable holes
- you should see the volume increase on your ipod.
- if you don't hear sound, unplug and plug back your headphone.
- Now remove the dock connector and test your switches. Do you get the right kinds of resistances?
- If you see anything other than infinity on your meter, you have either
a short circuit: crossing or stray conductive material OR
the holes in the felt are too big and so the conductive fabric are touching even when you're not squeezing.
- Third, attach yarn to dock connector, measure the resistance across the two holes. It should be very high (100s of kOhms or even MegOhms).
- Press each switch and monitor the resistance *at the holes* on the board. If you don't register a change, there is a break in your circuit somewhere.
- Fourth, plug it into iPod and click your soft fabric button. It should play/pause a song. Even if no sound is coming from the iPod, you should be able to see a visual change from play to pause.
Still Nothing? You must have bad circuit mojo. Please turn in your credentials.

* Please be careful with your expensive electronics. This stuff works, it really does, and has caused no harm to any of the iPods/iPhones we've used with it. That said, we can't be held liable for any damage that might occur to your device, so please use this guide for informational purposes only. Cool? *
