Handspring Visor Edge? I had the metallic silver model (and still do). It sports a blazing fast 33 MHz CPU and 8MB of RAM. I've kept it over the years because it still works ... and because I think it's a great design. I especially loved the weight, shape, and feel of the little stylus. That stylus happens to be metallic.
You see where I'm going here. Since the stylus is metal, all that I needed was some sort of conductive tip.
Here's what I came up with. It works great as long as any part of my hand is touching the metal pen (which is hard not to do). It looks nice (I wouldn't say it's beautiful, but I think it looks better than most homemade styli). It's compact and easy to tote around. And here's the best part: the tip offers far more accuracy and draws a thinner line than commercial or homemade conductive styli that I've tried or seen demonstrated.
Here's how I made it:
About the rubber foot. This may be the hardest bit to find, but it's something you should be able to pick up at a hardware store (or, at least, you can find something similar). I cut off part of the foot as seen in the photo above, then drilled a hole into the rubber that would tightly fit the metal stylus. Other materials will also work. I made an earlier model with a cheap wood plug using the same method. It worked well, but isn't as flexible (meaning that you may have trouble with the wood cracking when you drill into it). Rubber works best.
So that's all there is to it. It's a bit more involved than most of the DIY capacitive stylus tutorials you'll find on the web, but I think it's worth the effort. It works great. It looks nice. It's a great way to recycle a peice of old tech. I've been using it for a while and the aluminum is showing no signs of splitting. If it does split, it's a relatively simple matter to rip off the tip and make a new one. If you don't have an old Handspring Visor Edge in your closet and want to try this, would you believe that you can still buy a metal stylus?
