Warning, this device involves fast spinning objects and high torque motors. Letting it go for the first time is kinda scary. Watch your eyes.
Randofo gives this his seal of approval of awesome, so expect it to be in the next 62 projects to make with a dead push broom.
Below is a video of the death bringer. Thanks Matt for putting yourself in harms way.
Step 1: Supplies
1 push broom brush
1 6v lantern battery
1 large 12v motor (a machined shaft helps)
2 pipe clamps
1 piece of scrap acrylic or wood
1 on/off switch
Step 2: Attach the Acrylic Piece
I attached the acrylic with a regular nut on one side and an acorn nut on the other.
Once that it done turn it on to see if it vibrates enough, if it moves all around, then you did it right.
Step 3: Attach to Broomhead
Make sure the pipe clamp is nice and tight.
Step 4: Attach Battery and Wire Switch
Then wire up the switch so you can access it easily, you don't want a bristlebot running around with no way to turn it off.
Step 5: Tape Up Counterweight
Step 6: Test Ride
I let it run around the sidewalk, people gave me weird looks of course. it had a hard time going in a straight line and did fall down a lot.
Randy had a great idea of building a second one and attaching dremels to both of them. I questioned this being a good idea, his retort was "It'd Be AWESOME", can't argue with that.
Coming winter 2010 Bristlebot Battles on the Discovery Channel.
Please comment if you think this is an irresponsible use of tax payer dollars and/or feel i am putting children at risk for building such a device.
