IR Detector for Robot - Some of the companies put two transmitters, one on
each side of the detector, to get a good field of coverage for the front of the 'bot
and to detect left and right. 'Robots, Inspiration to Implementation has a great
schematic that you can use to build one of these. I used all Radio Shack parts for the
one I made and it cost about $10 to build. This detector will NOT detect black
flower pots nor the bottom of boots (grin)....(electronic circuit added 7/03)

IR RC5 Remote Control Transmitter - All remote controlled projects from this
site can be controlled with remote controls which use the RC5 protocol, like the
TV-remotes from Philips. When all buttons from such a remote are in use then you could
make a remote control by yourself. Your own build remote control with only one button
or maybe you want to build a remote with more then hundred buttons. It is possible,
however, you need the PIC Basic compiler from Crownhill seeing that everyone has his
own wishes and you have to fill….... |

IR Remote Control Repeater - This circuit receives the signal from a IR
remote control, like those used to control your TV or DVD player and allows the signal
to be repeated in another location. Having built a version of this using a 555 timer
from a circuit I found on the web (see here) I thought maybe I could use a

IR Security - This unit uses one TSAL6100 IR/LED emitter from Digi-Key.
This IR diode has a narrow (10 degree) radiation pattern at 940 NM. It is driven via
2n2904 transistor for maximum current pulses. The detector is a Vishay TSOP4838 38Khz
integrated receiver module. The 38Khz signal for the emitter is generated in
software....[Luhan Monat - Mesa Arizona] |

Isolated Probe - This probe allows connecting to such 'floating' circuits to
a normal scope input. As seen in the circuit, it is based on using an
optocoupler. The one shown in the diagram is a dual unit, but I had a pile of
them here, so thats what I used. …....) [Luhan Monat - Mesa Arizona] |

Isolated RS232 for PIC16F84 - Use of the opto-isolator to separate AC line
volatge and RS232 COM port. Simple circuit and useful idea for program development.
