TOUCHPAD HACK - How to transform a touchpad into a useful mini graphics tablet with some simple everyday items

Step 1: Making the Pen Step 1

Get yourself a long phillips head screw. This will simulate the tablets pen. And youll also need a small 1.5 volt battery.

Step 2: Making the Pen Step 2

The final item is a small ball bearing. You can find these on any dog tag chain. Just snip off one of the balls.

Step 3: Making the Pen Step 1

Now place the bearing in the top part of the screw and place the battery ontop of the bearing. Make sure the battery's positive side is on the opposite side to the bearing.

Now simply tape the screw, bearing and battery together leaving only the batteries positive side exposed.

The ball bearing allows the battery to rotate and remain flush with the touchpad whilst in use

I have taped over the screws thread to make it more comfortable to hold

Step 4: Using the Pen

Now that your pen is ready simply place it battery side down on your touchpad using one hand and use your other hand to depress a mouse button....and draw away.

HOPE YOU ENJOY!

    I don't know which would work better, but upon seeing this, I decided to borrow my mother's Wonder Woman stylus, for touch screens, to see if it would do the same. It worked!

    great instructable! any idea to make this pressure sensitive? maybe using the pressure-sensitive pen of a standard tablet on the touchpad?

    Thanks again!

    To give yourself a finer drawing tip you could put another ball on the positive (drawing) side also. Just make sure the tape can hold it in place and leave enough exposed to complete the circuit.

    yep, run>"eudcedit.exe" (without quotes) it's a character creator (not font maker)
    Try fontforge

    a really sweaty hankie would do the job as well. a damp one, not a wet one should work just fine. get one corner and twist it into a cone and you have a touchpad pencil. the salts in your sweat are transferring the electrical current from your body into the touchpad.

    why does a battery make it work?

    The battery simulates capacitance (the body's faint electrical charge). That's why using a Q-tip or regular pencil won't work. No electrical charge. The wiki article for "Touchpad" talks a bit about this. http://en.wikipedia.org/wiki/Touchpad

    Would it be possible to forgo the battery and conduct the body's capacitance through the pen instead?

    Pretty nice, do you know if there is a way to make one in an actual pen shaped object?
