Roach is a simple robot that uses two Cadmium - Sulfide Photocells to detect light and uses two AAA batteries also. It follows light. If there is more light on the right side of the roach the left motor will turn on and the right motor will turn off allowing it to turn right. If there is more light on the left side of the robot, the right motor will turn on and turn off the left motor allowing it to turn left. But if both Photcells detect light it will go straight. |

This lock is a four digit code lock. It uses one 9v, one relay, one IC, two transistor, two capasitors, eleven resistors, and five diodes. I thought that this project would take more pieces but i guess not. This lock can be installed to almost any door, and it would be on my door but my parents wont let me put it on. |

This alarm does not have a bell connected to it but it would still work with out one. When two wires are separated or something trigers the alarm, the bell starts ringing. |

This is a snooper. It is 1 X 3 inches. It uses a 9v, has a 10 inch antenna, and has a great mic. This snooper can hear everything goin on in a room and it will send everything it hears to a radio up to 100 feet away. All you have to do is adjust the pot resistor and the coil so it sends what it hears to the correct radio station. Sends between 85 - 92 F.M. Easy to hide and fun to use. |
