Step 1: Materials

Picture of Materials
To do this you will need the following materials:

Bare Paint Pen
Drawing Pencil/Pen
LED
Cardboard
Ruler
Scissors
USB plug/port

Step 2: Step 1: Mark your USB contacts

Using a ruler, mark two points on your cardboard which are 5mm apart. These will be the lines from which you will draw your Bare Paint circuit. These should be centered within two 12mm lines which will mark where you will cut the cardboard to fit into your USB port.

Step 3: Step 2: Draw your Mouse!

Using a Bare Paint Pen, draw the circuit outline of your mouse. Make sure the two bottom lines are 5mm apart so that the tail won't short circuit in your USB port!

** Notice the gap at the top of the Mouse's head? This is to ensure your circuit works. Make sure you leave this space!

Step 4: Step 3: Attach your LED

Using your Bare Paint Pen, glue your LED at your Mouse's whiskers. This way it will make a lovely nose for your new pet.

Step 5: Step 4: Cut out your Mouse

Using your scissors, cut around your mouse to outline its body. Remember the tail must be 12mm wide in order to fit into your USB port.

Step 6: Step 5: Let your circuit dry

Once your circuit is drawn out and your LED attached, let your drawing sit for 5 to 10 minutes until it is fully dry. Once it is no longer tacky at the touch you can bend the tail forward at a 90˚ angle so that your mouse will be upright when put into the USB port. If you think the corner may crack just put an extra dollop of paint in the crease to reinforce the bend of the circuit.

Step 7: Step 6: Now you can test your Mouse!

Make sure the paint is 100% dry so that you don't introduce any wet paint into the USB port. Once you are confident it is dry you can carefully place your Mouse's tail into your USB port.

Step 8: Step 7: Watch your Mouse light up!

Blew my led. Whoops.
Can I use any pen, or is Bare paint a certain kind of ink that just happens to be chemically formulated in a way that makes it conductive?

Hi Shadowyblade,

To answer your question Bare Paint is specifically formulated to be conductive. There are other paints that will conduct a current, however ours is the only one which is a totally non-toxic and consumer friendly material. No fumes, no rashes!
