Introduction: Bristle Bot From PS2 Controller Motor

This is a variation of the now common bristle bot. It is a bit bigger, using 3 AA batteries and the vibration motor from a PS2 game controller

Step 1: Materials and Tools Needed

For materials, you need:
- 4 identical toothbrushes
- A three-position AA battery holder
- 3 AA batteries
- A dead or unneeded PS2 Controller or similar
- A SPST switch
- A bit of extra wire, 24g insulated (possible)

I got my toothbrushes for $1 US at, where else, the dollar store. The batteries and holder were sitting around. The PS2 controller I bought simply to take apart anyway. The switch is from my parts cabinet.

The tools needed are the basic builder stuff:
- soldering iron
- hot glue gun (with glue)
- wire cutters
- wire strippers
- you may need a file to clean the contacts of the battery holder

Step 2: Assembly

Remove the motor from the PS2 controller. Note that there may be some open holes on the back, cover these with a tiny bit of tape to keep hot glue from jamming the motor. Using the hot glue, attach the motor to the side of the battery holder, on the opposite side of the battery terminal clips. Make sure the motor is centered side to side, as if it is not centered the bristle bot may tend to turn in one direction.

Step 3: Assembly (continued)

Remove the motor from the PS2 controller. Note that there may be some open holes on the back, cover these with a tiny bit of tape to keep hot glue from jamming the motor. Using the hot glue, attach the motor to the side of the battery holder, on the opposite side of the battery terminal clips. Make sure the motor is centered side to side, as if it is not centered the bristle bot may tend to turn in one direction.

Step 4: Assembly (continued)

Attach the four toothbrushes to the bottom of the battery holder using hot glue. Each should orient the same way, and should assemble to all the same height. I canted two of the toothbrushes in to avoid a ridge on the perimeter of the battery holder, this ensured identical heights for all the brushes.

Attach the switch to the side opposite the motor, next to the battery terminals

Step 5: Wiring

The wiring of the bristle bot is very straight forward. The polarity of the battery and of the motor leads is not important. Connect as shown in the diagram. If desired, the connections can be sheilded with electrical tape.

Step 6: Now Play!

The bristle bot seems to prefer a smooth flat surface. It tends to turn when encountering an obstacle, so flat rulers work great for keeping this critter coralled.



Enjoy!

Good instructable......but gee whiz, that might be the shortest video in the history of Youtube!!

Hi there, do you have the datasheet of this dc motor?

could you use a different on/off switch, just make it so it goes when you plug the battery and get rid of the switch all together?

i used a reed switchso when it detects a magnet it moves so i put a magnet on my ring and amazed mi frineds thanks ps.would it be ok if i made a few of these to sell?

i'm looking into purchasing a top-of-the-line hot glue gun, can anyone recommend one? I bought a martha stewart brand one a few years ago but it was a piece of crapola.

Check out the Dremel 1200-01 Hot glue gun. Has two temps, a flattened handle, and a silicone guard over the nozzle to prevent burns to your hands, plastic you are gluing, or worse: the power cord. Oh, and it also has an on/off switch. A feature absolutely essential in a glue gun, but missing in every glue gun I have ever purchased before, including the $30 one I bought not too long ago.

You could use two moters and have one doing up/down and the other doing left/right. Make a ball of brushes and put the moters into the middle. Watch it roll...

hmmm you could make scrathy bot with a bunch of wire brushes, a pokey bot with an old heatsink and a stabby bot from a bunch of exacto knife of similar blades...
