So you don’t like a stylus, but you don’t want to get your iPhone screen all dirty either. Easy solution, build a knob that will simulate the act of touching your iPhone screen. This is an easy build, but it’ll take some tweaking to get the fabric in the right places to work properly.
It’s pretty easy to build, just get some conductive fabric, a knob, and some glue. Check out the video for a demo and complete instructions on how to build it. You could even substitute the knob with something else if you’d prefer.
