We were aiming for a buggy like bristle bot. You be the judge.
Ok, it would have taken a lot less longer if I had done all the work but I figured it was a good time for my daughter to learn some new skills.
She learned the value of testing each step and each connection before going on... she wrote up her own version of this instructable. We shared the photos.
Caveat: I wouldn't trust anyone under 16 doing this activity unsupervised. Heat. Knives. Melting things. Not generally a good mix for the unsupervised immature or inexperienced.
Caveat: Work in a well ventilated area.
Step 1: Tools and Materials
- Old CD
- three tooth brushes
- single filament wire (50 cm or so)
- 2 AA batteries
- rubber bands to hold down battery case
- battery case
- hot glue
- pipe cleaner (or similar strong flexible wire)
- soldering iron
- small DC motor
- alligator clip
- LEDS (two)
- plastic bottle caps (or similar 'junk' for the vibratory motor platform)
- alligator clips on leads
- wire sheathing
- lighter for heating sheathing
Step 2: Make the Vibrating Motor
Step 3: Attach Brushes to CD Platform
We chose the dull side of the CD for attaching the brushes. I am hoping to run the bristle bot in the dark and hopefully get a little LED reflection off the CD.
Step 4: Wire Up the DC Motor and the LEDS
Step 5: Mount the Motor Platform
Step 6: Attach Attenae LEDs Using Pipe Cleaner
Step 7: Glue the Vibatory Motor to the Top of the Platform
Step 8: Cut Up a Dead CD Player for the Battery Holder
If you are melting plastic make sure you are in a well ventilated area!
Step 9: Rubber Band the Battery Case Against the Cap Platform
Step 10: Weave LED Wires on to Pipe Cleaner Antennae
Step 11: Connect Wire Leads to Battery Leads and Have Fun
Your three head bristle bot should be ready to scrub now! Connect the leads from the LED and motor to the battery case and watch it go. Ours just goes in circles for now but I'm thinking that adding weight or another V. motor might fix that.
It was a lot of fun to build!
