Infrared Remote Control operates on 115 volts AC - This circuit
will allow you to turn on any piece of equipment that operates on 115
volts ac. The receiver circuit is based on the Radio Shack infrared
receiver module (MOD), part number 276-137. It is also available from some
of the other sources listed on my Links page. The MOD accepts a 40khz IR
signal that is modulated at 4 khz. When a signal is received the MOD will
go low. The sensitivity of the MOD is set by different values for R1 and
C1. The values for R1 may need to be as high as 10,000 ohm.....

Infrared Remote Control Tester - Using a battery, a
phototransistor and a visible-light LED, this simple circuit is a go/no go
tester for IR remote control devices. The illumination of the LED
indicates that Q1 is being modulated by IR energy…. |

Infrared Remote Control Tester - This circuit is the result of
my research. I have used a photodiode, SFH2030 as an infra red sensor. A
MOSFET opamp, CA3140 is used in the differential mode to amplify the
pulses of current from the photodiode. LED1 is an ordinary coloured led
which will light when IR radiation is being received. The output of the
opamp, pin 6 may be connected to a multimeter set to read DC volts. Infra
red remote control strengths..... [Andy Collison designer] |

Infrared Remote Control Timer - This infrared remote control timer can be
used to turn an appliance on/off for a period of 0.11 second to 110.0 seconds. The
circuit comprises two sections, namely, the transmitter section and the receiver
section..... |
|
Infrared Remote Controller - The transmitter is built around two CMOS 555
timer ICs (TLC 555s). The transmitter generates a modulated 35-kHz IR signal. The
35-kHz carrier frequency is generated by IC2, and the 1 500-Hz modulating signal is
generated by IC1. The output of IC2 drives LED1 through resistor R5; that LED
provides.....(Circuit design added 06/09) |

Infrared Remote Extender - This electronic hobby circuit is designed to be
placed directly in front of a standard TV or VCR remote. The exiting light pulses
produced by the electronic circuit match the pulses from the remote but are about 10
times more powerful. Using the device, the remote can operate a TV or VCR over three
times the normal distance. …. [Hobby Corner Circuit by Dave Johnson] |

Infrared Remote Jammer - Don't like your little brother's TV channel
selection? Hate the volume your wife sets the stereo at? Want to just annoy
someone?This circuit does all that and more by jamming most IR remote signals. The
circuit releases a flood of pulsing IR light that confuses the reciever by corrupting
the data stream..... [Design by Aaron Cake] |

Infrared Transmitter / Detector - This circuits consist of two parts, the
first part will transmit a signal upon press of a button, and the second part will
detect that signal and trigger a relay....kinda like a simple remote control....

Infrared/Ultrasonic Beacon - The whole transfer-protocole may be omitted, if
the receiver-circuit is changed at the D/A-converter stage. Replace the 4-bit
converter by a well-designed 8-bit device. This increases dramatically the
positionning speed. But for didactical purpose the 4-bit converter is a marvelous base
to teach serial information transfe [Boulette's Robotics page] |

IR distance ranger covers 1 to 20 cm - 11-Apr-02 Issue of EDN
Commercially available IR distance rangers typically handle a 3- to 30-in. detection
distance. Many times, it is necessary to determine smaller distances. The circuit in
Figure 1 is useful for measuring small distances to reflective surfaces. Its
measurement range is from less than 1 cm to approximately 20 cm for a flat, white
surface..... [Design Idea by Paul Florian, McKinney, TX] |
