you don't have to spend a lot of money on a tablet stylus. This hack uses a standard arrowhead eraser, a metal paintbrush and some craft foam to keep it all in place. The end result is a good-looking, nicely sized stylus, and if you use a metal paintbrush and have an iPad 2, you can just attach the stylus to your tablet magnetically.
The only trick here is collecting the materials. If you have this stuff lying around already -- a paintbrush from a watercolour kit or old paint set, a typical eraser and some conductive foam that comes in just about any gadget's packaging -- then this will only take you a few minutes to assemble. Even if you hit the craft store, the materials won't cost you more than a few dollars. To assemble the stylus, you'll need to cut the cap off of the eraser and use it to fit a corner of the foam at the hollow, top end of the paintbrush. As long as the chunk of foam you use is large enough, it should fit snugly, and the eraser needs to touch the metal part of the brush in order for the foam to be conductive when you touch the metal body of the stylus.
That's all there is to it. You can see from the video above that the results are good, and the stylus attaches to the iPad 2 specifically well because of the magnets in the body. It's a quick, fun and easy project, and while you could always order a stylus for a couple of bucks from the internet, this is a viable option if you prefer to make instead of buy whenever possible.
