Children like to play with the toys equipped with the motors and capable to move. But even they quickly bother if the child made them not. If he was involved in process of creation of a toy, it will not bother it much longer.
Instruction
1. Take the motor from a faulty cassette player. They are much more durable, than those which are specially intended for application in toys, thanks to use of the metal back bearing.
2. Connect parallel to the engine diode 1N4007 in the return polarity (the cathode to plus, the anode to minus). At the engine the red wire is intended for connection of a positive pole, and black - negative. It is impossible to reverse the polarity it because of a specific form of brushes - from rotation in the opposite direction they will quicker wear out. The diode to a zashuntiruyta the condenser on several dozen or hundreds of nanofarade.
3. Try to connect to the engine, observing polarity (that the diode did not open and did not cause short circuit) one AA or AAA element (even in case the player is calculated on work from two - in it tension on the motor moves via the special regulator). It has to begin to rotate.
4. In mobile toys of manufacturing the movement is transferred to wheels through a reducer. Production of a reducer in house conditions - troublesome business. Therefore arrive in a different way. Get on a shaft of the engine the small clown. And then just paste it to the easy platform as which it is possible to use, for example, an overdue discount or payphone card.
5. To the same card paste a compartment for a battery and the small switch.
6. Put a card details up on a smooth table and turn on the engine. The child very much will like to watch how the toy chaotically moves on a table. You watch that it did not fall.
7. Having made two toys, it is possible to organize competitions in so-called robotic sumo. On the plane the square with the party approximately in half-meter is drawn, in its center both toys are located. They begin to push with chaotic movements each other. The toy which is pushed out out of square limits is considered lost.
