The iPad is quickly becoming the go-to device for a lot of different kinds of mobile computing. That being said, there comes a time when a stylus has to be used. There are a few different available, but none of them gave the results that I-Wei wanted, so he decided to make his own.
The stylus that I-Wei came up with is based on a lead holder that architects, drafters and artists use. They're like mechanical pencils, but for larger leads. The 2mm lead holder is perfect for this build. You can get them at any artist shop for about $10. You might even have one around the house. You'll need one that has a long metal tip. It should be around an inch long. The build involves creating a custom nib and lead so that the lead holder can be used as a stylus. The resulting stylus is very comfortable to hold and gives excellent results.
This stylus uses conductive foam, which can be found in the packaging of certain microchips and computer parts. It's something quite easy to find, but if you have trouble, just ask a friend who's involved with electronics. Some computer and specialist electronics stores might have some on hand that they'd be willing to give you for free.
For his stylus nib, I-Wei is using the middle part of the conductive foam, which is softer and is easier to work with. The foam has to be roughly shaped like a tip using scissors or a utility knife. Once this is done, you'll need to super-glue it to the tip of a cotton swab. Then, you can shape it some more using a utility knife or scissors. He noted that a round shape works best. All that's left is to insert the cotton swab tip into your lead holder and you're done. Make sure that the tip of the lead holder grabs onto the conductive foam.
