Infrared AudioTransmitter & Receiver System
|
Infrared Transmitter and receiver for audio - Mono. Consists of a transmitter that generates an FM carrier and places this on an infrared light beam, and a receiver that detects this light beam, recovers the modulation, and amplifies it to drive a small spealer or headphone. Up to 1 watt audio output. Useful for private audio listening, infrared communication, remote sensing, security applications. Signal is undetectable visually or with a surveillance receiver. Both units operate from 9 to 12 volt DC supplies. |

|
Infrared AudioTransmitter & Receiver System 2 channel |
Same as mono unit except includes separate Infrared Transmitter and receiver for two audio channels. Can be used for Stereo audio or simultaneous transmission of 2 audio channels for separate purposes, dual language applications, etc. |
|
|
Electrometer amplifier system for meters |
Ultrasensitive Meter 0-30 V AC-DC 100000 Meg input. This kit uses any surplus 0-1 ma meter movement to make high impedance DC measurements. Useful for science and electrostatic experiments, static charge detection, insulation testing, etc. |
|
| Carrier Current Receiver for AM systems. Use as a receiver for AM carrier current broadcasts, in conjunction with our AM88 transmitter. Operates from 12-14V DC supply. |
|
|
| Carrier Current Receiver for FM systems. Use as a receiver for FM carrier current broadcasts, in conjunction with our AM88 or CCTR carrier current transmitters. Operates from 12-14V DC supply. |

Novel LED thermometer |
A novel thermometer using ten LEDs driven by a bar graph meter circuit, useful for temperature sensing. Has solid state temperature sensor. LED indicates temperature in 10 steps. An interesting science experiment demonstrating temperature sensors and bar graph displays. Can be calibrated over any desired temperature range between 0 and 50 deg C Outputs can be used to trigger alarms, fans, etc. |
