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.

Serial Infrared Remote Controller - a simple, cheap device that can be
connected to any serial port to control most components that have infrared
remote controls, includes schematics for receiver and transmitter (added 4/02)

Serial-driven IR remote Controller - This paper describes a serial
infrared transmitter (SIT) capable of generating the infrared
codes used by most current equipment that incorporates an infrared remote
control. It is operated by a computer through an
asynchronous communications port. Driver software....(electronic

Short DC power-line pulses afford remote control - 25-Oct-01 Issue of
EDN If you face the challenge of adding a second, independently controlled
light source to an existing ceiling lamp controlled by a wall switch, you may
find that stringing a second power line is impossible. First, you can replace
the wall switch by the circuit in Figure 1. Pushing the on switch S1 or S2 for
approximately 1 sec inserts the 12V zener diodes D1 or D2 in series with the....

Simple 4-CH Remote Control - You can construct your own long range infrared (IR)
wireless remote using Motorola's MC145026 emitter and MC145027 detector chips. With your
remote you can control devices up to 20 feet (7 meters) away. It operates similiarly to a
TV remote. You just point the emitter at the detector, push a transmit button. The
detector then interprets your data signal. You can use this circuit to remotely turn
on/off devices (like a motors, relays, home appliances). ….(electronic schematic added

Simple Remote Control Tester - Here is a handy gadget for test- ing of infrared
(IR) based re- mote control transmitters used for TVs and VCRs etc. The IR signals from a
remote control transmitter are sensed by the IR sensor module in the tester and its output
at pin 2 goes low. This in turn switches on transistor T1 and causes LED1 to blink. At the
same time, the buzzer beeps at the same rate as the incoming signals from the remote
control transmitter.... |

SMS remote control v2.2 - Control up to 8 devices ( On-Off or Reset) by sending
a SMS message from any mobile phone, to ericsson T10s, of our circuit.….(design added

Solar Charged LED Utility Light - Tired of always spending money on flashlight
batteries only to have them fail just when you need them? Try this simple circuit out. It
would make an excellent science fair project. The white LEDs are quite bright, they
provide enough light to illuminate a small room at night. The LEDs produce a nicely
focused beam. You can read by the light of this device. [G. Forrest Cook] |

Super Remote - Using a PIC12F683 and a few transistors, it is theoretically
possible to boost the power to a standard 433 MHz remote transmitter module. (Note
hypothetical image at right).….(electronic schematic added 08/08) [Luhan Monat - Mesa
