Step 1: Materials
You will need:
2-AAA's (I started off with AA's, but they were too heavy so I switched)
1-Hot Glue Gun
And a Boatload of Hot Glue
Step 2: Making the Frame
First, cut the heads of all three toothbrushes.
Then trim the bamboo skewer into three pieces that will make a triangular frame.
Finally, hot glue it all down.
Step 3: Add the Platform
Flip the frame over onto its back. Then trace its outline onto a used gift card. Cut it out and test it to see how it fits onto the frame. If it fits, hot glue it on. Save your scraps from the gift card though, because you will need it for the next step.
Step 4: Attaching the Motor & Testing It Out
Use the scraps to attach the motor so it is standing upright in the center of the platform. It is a little tricky, so be patient.
Then rubberband the batteries to the bottom and use alligator clips to start 'er up! When it works, take the rubberband and alligator clips off.
Step 5: Finish It Up!
For the last time, hot glue the batteries to the bottom of the frame. It should stay just off of the ground. If it doesn't, get a new battery case. Then trim up the wires and add a switch.
Step 6: Celebrate!
Enjoy your new bristle bot!
