I've seen several instructible a on this project but I have yet to see one that can attach, and detach from you device. So, I created one.
You are going to need
3/4 inch (I think) Copper pipe
3 Q tips
An old headphone plug with wires (I got mine from old earbuds that I didn't like or need)
Step 1: Cutting the Pipe and Inserting the Q Tips
First you are going to cut the copper pipe into the desired length. Then you are going to bunch 3 Q tips into the cut copper pipe. Now you are going to want to dip the tip of the stylus (Q tips) into water and let them dry.
Step 2: Attaching the Headphone Cord
Now you want to cut the headphone cord to the length that you would like it. After you have done that you can insert it into the end of the copper pipe that the Q tips aren't sticking out of and then put hot glue into that end to keep in the wire and to seal that end.
Step 3: Finished
If you would like, now you can pretty up your stylus and make it look cool. If you made a cool one take a picture and post it in the comments. Also, I realized that this stylus can work on a laptop trackpad as well as touchscreens. Thanks for reading.
