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.

Step 2: Cut Down the Metal Sticks
Clamp the rod down and mark 9 inches in with some tape and go to town with whatever you have to cut with. (Remember, you should be wearing eye protection and probably a breathing mask - especially if your using a Dremel!)
Once you have the stick cut down, polish the ends with some sandpaper or a rasp (or your Dremel).
Finally, cut some grooves an inch or so in on one end. This will give the string something to 'catch' and keep the drumstick head from sliding off.
Step 3: Make the Pad.
Step 4: Wrap the Pad on the Conductive Fabric.
Cut a 3.5" or 4" square piece of conductive fabric and put it on a flat surface.
Put your musrhoom head, top down on the fabric. Hold it in place with the 9" stick you just cut with the groove side towards the pads.
Bunch up the ends however you can. Try to keep it as neat as you can; dont worry: neatness doesn't count.
Step 5: Tie Off the Fabric.
Trim off whatever you can with some scissors. Optionally, you can run a dab of fabric glue on the ends of the conductive fabric to help keep it from fraying.
Step 6: Happy Drumming!
