Ref: 80-105
80-105, Voice Changer
Your voice can be changed to add a vibration, like those used to disguise secret witnesses. Or, you may change your voice tone upward or downward; women sound like men and vice versa. Includes a very ROBOTIC voice as well. A microphone and speaker are included on the PC board, all that you need to add is a nine volt, transistor battery. This is a very novel and entertaining circuit.

MK120 Infrared Light Barrier Kit |
|
|
Ref: MK120
MK120 Infrared Light Barrier Kit Infrared (IR) Light barrier electronic kit MK120 uses an IR transmitter emitter to project a beam of infrared light to an IR receiver detector. The IR light beam is used to monitor a doorway, a pathway, an area, a conveyor, etc. for the arrival or presence of a person or object. A buzzer on the detector loudly announces and alert when the IR beam is broken by a person or object traversing through it. IR Light Barrier Velleman
