IR protocol analyzer is universal software for automatic decoding infrared remote control protocol packets. To capture infrared signal from a remote control, it uses microphone input of a soundcard. The hardware you need to start decoding is minimalistic and easy to build, just plug a phototransistor to input of your soundcard.This Delphi-based software processes InfraRed signal from a remote control and compares it with its own database of known protocols. When a match is found, packet is decoded and the software will display protocol name, description, decoded data and graph ...

This project shows you how to connect inexpensive calipers, micrometers and height gauges to PC through serial RS-232 interface and see the result using PC software. Its main part consists of minimal PIC to RS-232 interface, +5V/-1.5V power from serial port, and 1.5V to 5V logic level conversion. "The connector on the measuring instrument will have 4 pins, and the owner's manual will typically describe the output as 24 bit 90 kHz synchronous," said Kevin Timmerman, project designer.The caliper sends a burst of data approximately three times each second. Each ...

This project allows you to read many common EPROM and Flash memory chips. It's equipped with USB interface that uses FTDI USB to serial chip. The PIC18F4550 microcontroller firmware handles the various differences of the range of EPROM chips. The project only uses HyperTerminal PC software to control and read the chips. Intel hex and raw binary formats can be sent unencapsulated or by Y-Modem.Kevin Timmerman, project designer, said that there are no jumpers required for configuration. Power can be supplied on the appropriate pin by three 2N4403 transistors. A ...

The Laser Position Sensor (LPS) module is an optical sensor that measures and provides the two-dimensional coordinates of visible red laser light (630-694nm) shined onto its surface. This Freescale MC9S08JM8CLC MCU-based project developed by Joe Grand based on Roger Johnson and Chris Lentz’s 2-D Optical Position Sensor.The Laser Position Sensor has a resolution of 0.0001", an accuracy of 0.001", and a measurement range of +/-0.2" (+/-5mm). It can be used for remote device control, data communications, high-speed photography, long-range beam-break/security trip wires and positioning and alignment. If you want to ...
