Is that a masterpiece in your pocket, or are you just glad to see me?
Step 1: Materials
Used Altoids tin.
I added some pennies later on...
Step 2: Sharpen pencils.
Use my awesome lo-fi technique if you wish. Look at my instructable "Revenge of Post Office Drawings" for detailed steps.
Step 3: Cut pencils to length.
The inside of the tin is roughly 3/4" in height, so I'm going to trim the pencil leads to 1/2" to allow enough clearance.
I'm using some fairly specialized tools to do this: My tube-cutting jig and a jeweler's saw. Any other method will work, but I wanted a reasonable amount of consistency.
Set the back stop on the jig to 1/2", insert the pencil against the stop and engage the hold-down lever. Then cut through with the saw.
If you lose one or two, no worries, just chuck it up and resharpen.
Step 4: Assemble Stylus.
I laid out two strips of masking tape, roughly tin-sized, and attached the pencil leads to the sticky side.
After thinking on it a bit, I decided to add more tape to kinda ensconce the leads, because there was no way they would stick by themselves, and I didn't want the possibility of the paper sticking to the tape.
Step 5: Assemble Device.
Cut a piece of paper to tin-size, and place it inside. Put the stylus on top. Close tin.
Step 6: Something not quite right....
There's no way that stylus is heavy enough to leave marks on the paper, so I added some pennies to the back to give it more heft. I spaced them out enough that the tape would be somewhat flexible.
Ok, now close it up and...
Step 7: Get out there and walk out some art.
Jam it in your pocket and hit the bricks.
Step 8: Results.
Ok, so I cheated a little. After a while I noticed that the stylus was very limited in it's motion, so I removed about 1/3 of the stylus (two cents worth).
But don't tell anybody...
I had this in my front pocket at work for 8 hours after the modification.
