My Daughter Ate My Stylus — So I Learned How to Make a New (and Even Better) One

My Daughter Ate My Stylus -- So I Learned How to Make a New (and Even Better) One | 40Tech

My little girl is three. Three-and-a-half, to be exact — and before now, we never had to worry about her putting things in her mouth. I’m not sure what changed, really, but now we have to watch her like a hawk. And we do — but, unfortunately, it was already too late for my iPad stylus. For both of them…

The first one, she chewed on. It was pretty much a write-off. The second one, she decided it would be fun to see what the business end tasted like. Now I’m down two pens. They were the cheap kind, thank the tech gods, but that’s still about $40 down the drain! So I decided: the next stylus will be one of my own making. One that will cost me nothing to make, and that I can easily repair. And thanks to the wonders of the internet, making that happen was easy peasy.

There are several articles on the subject of the DIY touchscreen stylus. The ones that caught my eye were those talking about using a real pen. The basic touchscreen stylus isn’t exactly known for it’s ergonomic feel, so working one up from a real pen seemed like a good idea. I found a few iterations, but the basic concept can be traced back to a video on Make Magazine’s Makezine Blog. All you have to do is connect some light-gauge wire to some conductive foam — which can be found in the packaging of computer and electronic components such as microchips and CPUs — feed it through the empty body of a comfortable pen, and then wrap the wire around the outside, where your hand will come into contact with it. Trim the conductive foam tip to desired size and shape, and voila: instant iPad stylus.

The whole project can be done very quickly, and you can spruce it up a bit by drilling small holes to lock the wire inside the body of the pen, so that you don’t have to use tape. If you happen to have a pen with a metal body, even better. All you’ll need in that case is the conductive foam and you’re good to go! The wire method isn’t so bad, though. It’s not always pretty, but it works.

Here’s a (somewhat blurry) shot of my rough prototype:

I made this on a whim, entirely from things I had on hand. I was able to use the original stylus head for the conductive foam, which was nice — we caught her before she swallowed it. I also used some very light speaker wire (all I had, at the time), and the head of an old 1/4 audio jack to provide support for the tip. It fit snugly into the point of the pen, once the pen’s original head was taken off. Note that the wire is only on one side of the pen. I did that because speaker wire is ugly, and wrapping it all the way around would have been a total atrocity, potentially involving metal splinters. The way I hold a pen would have me almost always in contact with it, anyway, and the next round will be prettier.

Looks notwithstanding, due to the ergonomic grip of the pen, I’ve already found that the DIY iPad stylus is much more accurate than those that are up for sale. I’ll never go back.
