A few days ago I opened a thread at todoUMPC.com (Spanish) about how to make your own stylus. I wrote there about how I did it using a disposable poultry thermometer and and an old pen.
I took a lot of pictures of the whole process so you wont need any translation to understand how I made it. But... that's not all. In that same thread my friend Domenec posted how he made one using a fishing line and a lead pencil!
And guess how he called his invention: the fisherman stylus!
One thing is for sure, they are more comfortable than the original stylus shipped with UMPCs and PPCs.
Update: The fishing line that match a 0.7mm lead is the 50 pounds line.
