I had this idea.
I wanted a Sonic Screwdriver and an iPad stylus. So I went and bought a Sonic Screwdriver with the intent of making it a stylus.
Turns out all I needed was a no-scratch scrub sponge and some ‘wire.’
- My sponge of choice was the totally common re-washable one from 3M
- My metal was tinfoil.
- My Sonic was River Song’s.
Before I actually did this, I went and got an exacto knife holder from my civilized half (she does art things), put a wedge of sponge in, and tested. It took about an hour to sort out that what I needed was to run a large enough sponge-wedge in there, and then connect it via tinfoil to the metal, and thus, magic.
Now on to River’s! Hello, Sweetie!
The first step was to figure out how to wrap the wire. I didn’t want to drill a hole (though I have a Dremel and can do that pretty easily) because I was afraid of cracking the plastic. I ended up taking my time sorting out where I put my fingers. Do I hold it close up to the tip like a pen, or farther away like a brush. Finally I realized the options were run things outside, or use the detachable end where I change the batteries.
For what it’s worth, reason set in before I picked up my massive drill and made a hole in the end! I took the titanium drill bits and worked them through, smallest to largest, until I finally had a hole. I did it manually, and sanded the edges down. Took about an hour, while I Skyped with Podz and the boys. Amusingly, Nacin still can’t pronounce my name.
Now I had to get creative here, and figure out how to transmit electricity without frying anything I needed. Luckily, there’s tinfoil!
I shoved some sponge in the hole, screwed it back into place, and then trimmed off the foil. Oh yes, it works without me having to touch any foil!
The final product?
An alternate idea I had was to use some conductive ink and ‘paint’ on it, but I couldn’t find anyone who had done that (and given the risk, I was loath to try it myself). Also it’s surprisingly expensive (more so than just buying a damn stylus) and the paint washes off with water! Not what I wanted. Then I found http://www.thinkgeek.com/gadgets/tools/b70c/ – $4 from Think Geek. And they also sell Sonics! So if I do another, I’m going to try it that way.
