IR Extender 1A - This circuit is used to relay signals from an
Infra Red remote control in one room to an IR controlled appliance in
another room. [Circuit designed by Andy Collison] |
|
IR Extender Mk 6 - 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.....(schematic added 01/2010) |

IR Heart Pulse Monitor - Circuit diagram of a pulse sensor
circuit board out of a treadmill. Notice that the output is level shifted
for use by CMOS logic running on 4.5V regulated down from the 6V battery.
The CMOS logic also controlls the power to the analog circuitry and
infrared LED. I do not gaurantee the accuracy or safety of any information
herein..... [Reverse engineered schematic by Stepan Novotill] |

IR Modulation Detector - A circuit to extract and measure the modulated
carrier of an Infra Red remote control. Note that the circuit does not physically
separate control pulses from modulation, but amplifies the completereceived signal
allowing the waveform to be displayed ideally on an oscilloscope or a frequency
counter. Modulation frequencies between 1kHz and several MHz may be measured.

IR Opto Detector - This circuit converts infrared light into sound.
Modulated IR light, like that from remote controls, IR received by the
phototransistor and is amplified by the LM386 IC. The IC in turn drives a small
8 Ohm speaker…. [John R. Schuch] |
