Here's a video of the sticks using my iSteelPan application:
The sticks work in any application since they send the same sort of signal your hand does. I made a few iPad apps that are being submitted to the Apple store...till they become available, the Magic Piano is super fun with them: http://magicpiano.smule.com
Step 1: Get some supplies!
This is how the magic happens. Conductive fabric makes a finger like surface to trigger the touch sensors on the iPad or iPhone. It's not too expensive, but you can't go to Hancock Fabrics and pick it up. Thank you Internet:
http://lessemf.com/fabric.html has the most selection. In this instructable I've used their "Pure Copper Polyester Taffeta Fabric". You'll need about a 3.5" square piece for each stick you want to make.
In case thats too confusing, SparkFun has some too: http://www.sparkfun.com/commerce/product_info.php?products_id=9770
This is the second half of the magic. The metal rod will make the connection from your hand to the fabric. It's not as spooky as you might think. I bought a 4 foot 3/16" diameter rod at my local hardware store for 2 bucks.
You'll need some kinda cotton or poly string.
I bought some cotton pads from the drug store. You could use cotton balls, but pads are easier to work with, firmer, and stronger. This will give your stick a better feel and lessen the risk of the metal rod poking out and tearing conductive fabric.
Stuff to cut metal
You can do this as you like. A hack saw or a Dremel will work. I used a Dremel. If you're going to use one too, get some eye protection cuz sparks are gonna fly.
