The idea came from the Make: blog.
Collin's Lab: DIY iPad Stylus
@ Zebra F-301 Compact Pen
@ Anti-static Foam
@ Foil Tape
@ File, Sander, (lineman pliers)
@ Soldering Iron
@ Super Glue
The pens come in a two pack. Could do the mod to just one or to both pens?
Step 2: Disassembly and Filing Down Tip
Screw the tip back on and use a file to open up the hole. There is a point in the tip where it will open wider, this is where the foam will come through. Round off the edge to prevent the tip from scratching the screen if the foam starts to wear down.
Filing might take some time. Use cutting part of lineman pliers or a sander to get to what is shown in the last picture.Then use a file to clean up the edge.
Step 3: Adding the Foam
Use a soldering iron to make a hole in the area where the cap attaches to the body. The wire will be fished through the hole.Use of the soldering iron make a bit of a ramp that is easier to get the wire to come out of the hole in the body.
Screw the tip back in with the wire coming out of the hole that was made in the body. Use the soldering iron to melt a grove in the cap area for a striped part of the wire to sit in.
Step 4: Attaching the Foil Tape.
Cut a piece of foil tape to cover the wire. Aluminum or copper foil tape will work.
Put the cap on the end that has the foil. If the fit is a bit to snug remove the small o-ring on the end of the body.
