Make an Electric Octopus Badge!
This tutorial will show you how to assemble a Badge Kit. The Badge Kit is unique in that it uses a piece of cardboard which has been pre-printed with Bare Paint in the shape of a jaunty octopus with a hat. Your job is to poke some holes and attach a couple of components using Bare Paint as a cold solder. This is a fairly straightforward kit and we'd expect you to have your octopus bliking (or changing color) in 30 minutes (including drying time). Have fun!

**If you don't have the kit, all you need is some conductive paint, battery & LED's. You can make your own drawing and watch it glow!

Step 1: Components

The parts that you'll need:

1 x Bare Paint Pen (or any conductive paint to draw a circuit with)

2 x Octopus Badge (or any circuit drawing of your own)

2 x Badge Pins with stick back

2 x Coin Cell Batteries

1 x Blinking LED

1 x Color Change LED

**If you like you can get all these components as a kit from our online shop otherwise feel free to improvise!!

Step 2: Tools

Having a couple of tools will make the job easier. We'd suggest a pair of side cutters to clip the legs off of the LED's and something like an eyeglasses screwdriver to poke a hole in the cardboard.

Step 3: Step 1 - Making the holes

The first step is to poke holes in the cardboard so you can put the legs of the battery and LED through. Make sure to poke the holes on top of the + and - symbols. Make sure to remember which side is + and which side is - (hint, the right side is +).

Step 4: Step 2 - Inserting the LED

Put the LED through the badge with the positive leg (the longer one) on the right and bend the legs back.

In the photo above you can see the legs of the LED bent back. We do this so that the component is strain relieved. This way if your badge falls off or someone bumps it the LED will stay attached.

Step 5: Step 3 - Attaching your components

Take out your Bare Paint Pen and put a few drops of paint on top of the legs of the LED. You want to electrically connect the legs of the LED to the surface of the badge. Feel free to use as much as you'd like, but make sure that your blobs don't run together and touch or you'll short out the LED. Also put some blobs on the battery holes, this will make things easier later.

Notice that I was careful to make sure they weren't touching in the middle.

Step 6: Step 4 - Attaching the battery

Now, grab your battery. The battery has a + and a - just like the LED. The + is the leg that is attached to the top of the battery and it bends over the side. Because you've already put your paint blobs on the holes, just push the battery through the holes. It's easier to put the blobs down first for the battery as the - side of the battery is hard to access once the battery is on the badge.

To make sure your components are really stuck to the badge you can put some paint on the back as well. At this point, you can cut the legs of your LED shorter so they don't get caught on your jumper!

Step 7: Step 5 - Attach your badge pin

Remove the plastic paper from the pin and attach to the badge back. That's it, you're done! Wear your badge with pride!
