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 IC 2, and the 1 500-Hz modulating signal is generated by IC 1.  The output of IC 2 drives LED1 through resistor R5; that LED provides  __ Designed by Nicola Asuni - Tecnick.com

Infrared Remote Extender for IR remote controlled equipment -  This simple device lets you operate your CD/DVD player, set-top box (even the newest ones!) , VCR or other program source using its remote control from another room in the house.  it receives the signal from the remote control and relays this to the other room via a 2-wire cable.  An infrared LED then retransmits the signal to your remote controlled equipment.__ SiliconChip

Infrared Remote Home Control -  iR Remote Control for controlling home appliances can be easily made using Decade Counter CD4017, 555 Timer and TSOP1738 infrared receiver.  By using this circuit you can easily control your home appliances using your TV, DVD Player remote control or using a remote control circuit described here. __ Designed by Abhay Bajpai

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 __ Designed by Aaron Cake

 

Infrared Remote Volume Control -  This is a true 'minimalist' remote, having but three functions: Volume Up, Volume Down and Mute Volume is controlled by a motorized (motorized for US readers) pot rather than any of the 'digital' pots that now abound, and this was done for a number of very good reasons.  __ 

Infrared Switch Is Controlled By A TV Remote. -  Nowadays Appliances used to control almost any function with remote control.  But can not put the remote to control other electrical appliances.  We can do this project With the following Can be used with almost any infrared remote.  Can choose to work, or SPST switch or normally open pushbutton switch.  -There are output__

Infrareds for remote Control -  infrared based electronic circuit diagrams / circuit schematics __ Designed by Peter Jakab

IR Extender Mk 5 -  The latest addition to my collection of infra Red (iR) Repeater circuits.  The Mark 5 is a much improved version of the Mark 1 circuit and has increased range and sensitivity.  it is also immune to the effects ofambient light, daylight and other forms of interference.  in addition it works with iR modulation freuencies in the range 30 to 120kHz making the Mk5 circuit the best choice for compatibility with remote controls __ Designed by Andy Collison

IR Link -  This is a battery powered infra-Red Link that will allow you to change channels on your Satellite Receiver and operate the controls on your VCR & DVD from anywhere in the house.   __ Designed by Ron J

IR Proximity Sensor -  it is the same principle in ALL infra-Red proximity sensors.  The basic idea is to send infra red light through iR-LEDs, which is then reflected by any object in front of the sensor.  Then all you have to do is to pick-up the reflected iR light.  For detecting the reflected iR light, we are going to use a very original technique: we are going to use another iR-LED, to detect the iR light that was emitted from another LED of the exact same type! This is an electrical property of Light Emitting Diodes (LEDs) which is the fact that a LED Produce a voltage difference across its leads when it is subjected to light.  As if it was a photo-cell, but with much lower output current.  __ 

IR Remote Control -  Volume and mute are provided by this simple but functional circuit.  Suitable for all preamps.     __ Designed by Rod Elliott  ESP

IR remote control -  A simple one-channel remote control.  it will trigger a relay upon press of a button.   __ Designed by Aaron Cake

IR remote control extender -  This circuit is used to relay signals from an infra Red remote control in one room to an iR controlled appliance in another room.   __ Designed by Andy Collison

IR Remote Control Extender (Mark 2) -  This is an improved iR remote control extender circuit.  it has high noise immunity, is resistant to ambient and reflected light and has an increased range from remote control to the extender circuit of about 7 meters.  it should work with any domestic apparatus that use 36-38kHz for the iR carrier frequency.  Please note that this is NOT compatible with some satellite receivers that use 115KHz as a carrier frequency.   __ Designed by Andy Collison

IR Remote Control Extender (Mark 3) -  This Mark3 version of the infra Red extender is a special version designed to control appliances that use high frequency modulated iR remote controls.   __ Designed by Daniel Pozzi - Argentina

So, Bill's  project does just that.  His infrared (iR) receiver decodes the signals from remote controls and uses the data to individually turn on or off __  Gadget Freak-Case # 169

IR Remote Extender -  This circuit can be used to operate a VCR or CD player from another room.  it's really an infrared signal repeater.  The signal from the remote is received and then retransmitted over wires to an infrared LED.  The beam from the LED is then picked up by the receiving window on the VCR or CD player__
