Not really a PDN mod, per se, but IMO, a stylus makes browsing, pulling down the notification area, scrolling menus and browser windows, etc., on the PDN a much nicer experience (it allows for selecting those very small page links without having to continually zoom, for instance, and keeps your screen clean to boot), so I played around and came up with what I think is a nice option.First, go to your favorite Chinese restaurant and pick up a set of their chopsticks, or, if you have some wooden shish-kabob skewers, these work well, too.Using either the chopstick or skewer, hold it in your hand like you would a pencil and, using some sort of snippers/cutters (I use wire cutters), grab the stylus-to-be at a point you feel leaves the right length for comfortable future use and squeeze.Take the resultant piece you were holding, and either sharpen it somewhat to a smaller rounded point (chopstick) or dull it somewhat to a more rounded point (skewer) with sandpaper or nail file, and also smooth the end where you snipped (prevents snagging on things, etc.). Other options also work, like small diameter wooden dowels, etc. This next part is optional, but I think very worthwhile: Take some teflon tape (used on pipe threads to make a more waterproof or gas-proof seal) and figure out a way to make the best covering with it that you can for the tip you created in the step above. I made a multi-layer stack of 6-8 small strips of teflon, then cut this into some narrower width strips than the tape is by default, and stretched them over the rounded tip in a plus sign "+" orientation. Multiple layers works best as one or 2 are too thin and wear through. If you have some two-sided tape, this can be wrapped around the stylus about 1/2 inch from the tip to hold the strips of stacked teflon you are stretching over the tip.Next, I took some of the teflon tape and carefully stretched and wrapped it around the stylus, starting as close to the tip as I could, and ended my wrap right after the 2-sided tape. You can just stretch the tape really far at the last wrap layer until it breaks, and it will pretty much self-adhere to the underlying layer.What you end up with is a handy little stylus ideal for tapping almost any size area or sliding around over the PDN screen. The teflon is extremely slick, and leaves no residue (like a finger does) or scratches (like a stylus of some other materials might) on the PDN's screen.
