Capacitive stylus ANYONE can make

There are plenty of instructables out there about making a capacitive stylus, so why choose this?
In this instructable you only need things that any ordinary person has in their house. No more dealing with $100 slime thats only available from a remote island in south africa, just plain, household junk.

Sorry for the bad picture quality, i was using my iPod.

Step 1: Materials

You will need 

- Pencils

- A file

- The lid of a margarine tub or similar lid 

- A small mixing bowl ( Aprox. 1 cup )

- Something to mix with

- Something to be the shaft of your stylus

- Craft glue

- A knife

- A candle

- A drill bit (Preferably with a drill)

Step 2: Get your graphite, make your powder

Use the knife to split the wood of the pencil, then collect the pieces of graphite. Do this with at least two pencils, but you can always open more if you need to. 

Once you have a reasonable pile of graphite bits, start shaving them against the file. Make sure the resulting powder gets collected in your margarine lid. your going to need it. Also try not to breathe to much of it... probably bad for you...

Step 4: Prepare your mold

Put your powder aside for now and find a candle. Make sure it is one your mom doesn't want because your going to destroy it. Mine was too tall so I cut it in half. 

Next pull out the wick if it's in your way, and carefully drill a hole in your candle. The hole should be as deep as you want the capacitive part of the stylus to be, then 3/4 of a centimetre deeper. The hole I made was about 3 cm deep. The width of the hole should be a few millimetres wider than what you are using as the shaft go your stylus.

One question, if you don't mind, is it hard? Because I wouldn't want to scratch my screen.

It is hard. It becomes about the same as solid glue. When I used it it did not scratch my screen but if your worried about that then definitely use caution.

Hi! I would like to know what kind of file is that? I see a peace of metal is that correct?

Yes, it is a metal file. I can't remember exactly what type of file it is but any metal file will work as long as it isn't too coarse.

Will it work if you varnish the tip (I'd guess so?), that way you wouldn't be drawing with graphite wax on everything :P

To help with the needing to touch it, glue aluminum foil in a strip down the shaft, like they do with copper tape in the http://www.ladyada.net/make/drawdio/index.html

I'm not sure about the varnish, it's a fairly weak stylus already so the varnish could weaken it, but I've never tried. The graphite dries and doesn't come off much do leaving pencil marks isn't much of a problem.

I had not thought of foil tape... I will see if I have any "Allumitape" left from some other stuff :)
