My first introduction to Bristlebots...  was way back in 2007 - it's amazing to see the variety of creations grown from the roots of that project. 

Here is my variation on a theme.

The materials / tools list is pretty short... 

• Soldering Iron / Solder
• Flush Wire Cutters
• Needlenose Pliers
• 22AWG Solid-core Wire
• Pager Motor
• CR2032 Battery
• Googly Eyes
• Zip Ties
• Hot-glue / Super Glue

From start to finish, it shouldn't take more than 1/2 hour to 3D print your parts and assemble a Vibro-bug.

Small and simple projects... can be great fun!
