Bristle Bot II - From a Cheap Electric Toothbrush - electric toothbrush sale

There is also a pig stle robot, which is a discounted electric toothbrush.
I now know why it's on sale because it's not out of the box.
But it's okay, just for fun, isn't it?
Well, cut off the head of the toothbrush and tear off the internal organs.
I'm sorry I said it was a little simple, but that's what I did.
Maybe more details will help.
The head of the toothbrush is cut off with a two-wire cutting machine.
The internal organs of the toothbrush are extracted.
A needle and nose clamp was used, but it can be done with any pointed object on the head of the hand.
This toothbrush is cheap and cheap.
Did I mention it was not out of the box?
Yes, the battery is good. 6V.
Connect the battery and motor to the toothbrush with a hot glue gun.
Try to keep balance and symmetry aligned.
I did change from 1 new battery that came with the toothbrush to 2 ones with almost no electricity, about 1. 3V each.
Of course, the two batteries can provide more energy, but they can also make the components symmetrical and balanced.
The Usubg hot glue strengthens the spring to better connect it to the motor because the copper lead coming out of the motor is very fragile.
Then, twist the spring with a pair of pliers so that it presses to the end of the battery.
Robots should now hum happily and continue to intimidate cats and other family animals.
A simple piece of paper breaks the connection.
I have a short video but your TV is broken tonight. TBD.
This is faster than expected, but it will rotate.
I tried some bristles and changed my behavior.
Your mileage may vary. Have fun!
