LCD thermometer - Build your own temperature meter for fun. This project uses
the Microchip TC77 digital temperature sensor, a PIC16F871 microcontroller and a
7-segment 3˝ digit LCD. You can study the source code on how to drive an LCD
display…..(design added 02/09) |

Lie Detector (hackcanada) - The circuit diagram of the Lie Detector is shown
above. It consists of three transistors (TR1 to TR3), a capacitor (C1), two lights
or LEDs (L1 & L2), five resistors (R1 to R5), and a variable resistor (VR1). This
circuit is based on the fact that a person's skin resistance changes when they sweat
(sweating because they're lying)....(electronic circuit added 7/03) |

Lie Detector hackcanada - this circuit is based on the fact that a person's skin
resistance changes when they sweat (sweating because they're lying). Dry skin has a
resistance of about 1 million ohms, whereas the resistance of moist skin is reduced
by a factor of ten or more,....(electronic circuit added 7/03) |

LTC1099 Enables PC-Based Data Acquisition Board to Operate DC-20kHz - AN34
Linear Technology A complete design for a data acquisition card for the IBM PC is
detailed in this application note. Additionally, C language code is provided to
allow sampling of data at speed of more than 20kHz. The speed limitation is
strictly based on the execution speed of the "C" data acquisition loop. A "Turbo"
XT ....(app note add 1/06) |
