SINGLE IC FORMS SENSITIVE MODULATED LIGHT
RECEIVER
The circuit uses a very inexpensive C-MOS IC that is connected to a small
photodiode. Using a unique inductive feedback network, the circuit provides high
sensitivity under high ambient light conditions. It is a great circuit when you want
to extend the range of an optical remote control transmitter.

T V Remote Control Blocker - 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....(added 4/02) |

Telephone Operated Remote Control using PIC16F84a MicroController -
This design controls up to 8 devices using a PIC microcontroller (PIC16F84A)
connected to the phone line. The unique feature here is that unlike other
telephone line based remote control, this device does not need the call to be
answered at the remote end so the call will not... |

The Ultimate Universal Remote Control - Gadget Freak Case 147:
Couch potatoes should be particularly interested in Bill Bowden's remote control
IR receiver, which allows users to control the power of virtually any electrical
appliance (including those not equipped for remote) using their standard remote
control. It's based on an IR receiver circuit, |

TinyIR Learning IR Remote Control Receiver - Adding IR remote control to your
next project, or to an existing one just got a whole lot easier. With TinyIR, just apply
power, train the chip to recognize the key codes you want to use, and you're ready to go.
Code patterns are safely stored in internal non-volatile EEPROM. The chip can be
re-trained many times if needed.... |

TV/VCR Infrared Remote Booster - This circuit will boost the signal from any
infrared TV or VCR remote, extending the range by a factor of 3X. …. [Designed by David A.
Johnson] |

Two Wire Remote Microphone Amplifie - uses special amplifier module from Op-Amp
Labs (added 4/02) |
|
Two Wire Stepper Motor Positioner - A simple and inexpensive way to remotely
rotate a display or object is with a positioner that uses a stepper motor to rotate it.
The motor is driven by a circuit mounted near the motor and by a control circuit at a
remote location….. [free schematic from Golab.com] |

Universal Infrared Controller for a PC - This simple circuit allows you to
record any Infrared remote control signal on your PC, and then play it back. This is
particularly useful if you want to control appliances such as TVs, VCRs, CDs etc. from
your computer. The device simply connects to the parallel port of your PCThis circuit was
originally published in Electronics Australia, September1998 (added 4/02)

Universal IR Remote Control Tester - This tester consists of two integrated
remote control receivers whose outputs drive an LED to indicate when a suitable infrared
signal is received. To cover all current infrared remote controls, one receiver (the
TSOP1736) has maximum sensitivity to carriers at 36 kHz, the other (the TSOP1738) to
carriers at 38 kHz.….must register on this site.... [Published in Elecktor July/August

Universal RC5/RC6 Transceiver with PIC16F628 - This project is an expansion from
another project from this website. On the one side you can read the RC5, RC5X and RC6
codes from remote controls on a LCD and on the other hand you can send all thinkable RC5,
RC5X and RC6 codes to a device. Besides is for this project a PCB layout drew to make it
still more easier for you. ….(electronic schematic added 11/08) |

VCR TV Remote Range Extender Circuit - I often get frustrated by how poor some
infrared remotes in many new electronic devices operate. I used to be able to turn
on the TV from 30 feet away. Now, it seems that I have to get within 15 feet.
To address this issue, I designed the circuit shown below. The circuit taps into the
TV remote’s existing infrared LED and drives 8 more efficient devices. The result is
a communications range some 4 to 5 times longer.... [Designed by David A. Johnson] |

Video/Audio Wireless Transmitter - To design and build a wireless transmitter
that works over the FM frequency and allows the transfer of a video/audio signal over a
certain distance to a FM tuner.circuit diagram and project description (added 5/02)
