This PIC16F628-based compass uses NMEA-0183 data from a GPS receiver. The direction indicator displayed on eight-point LED with radial pattern every 45°. Although the GPS provides accuracy to a tenth of a degree, that kind of accuracy is not really necessary in the automotive use for which project is designed.To use the compass, user need to apply power to the GPS and to the display. After the GPS initializes, the display should show heading by illuminating one of the eight LEDs. If the GPS sends a "satellite warning flag" or ...

This small size GPS logger module allows you to record a route. You can mount it on an airplane model, car, bike or put it in your pocket to track your walking path. The project uses lipo battery as power source and PIC16F648 to read the serial protocol of the GPS or the computer and talking to eeprom. To view the route on Google Earth, A small Visual Basic program is used to retrieve the logged data and export the data in KML format.Joris Eights, the project designer, said to ...

The purpose of this project is to build a simple Theremin that can play the base notes (no sharps or flats) from one octave to another, specifically C4 to C5. Instead of using antennas, it uses infrared proximity to sense the position. The device will produce a specific pitch after IR proximity sensor detects the distance between your hand or an object from it. The project uses PIC 18F452 as main processor and Sharp 2Y0A21 or GP2D120 IR Package for the sensor.Chris, the project designer, said that PIC's internal Analog-to-Digital ...

This project is a PIC18F252-based repeater for GPS data. It is intended to connect to hand held GPS receivers that don't have external antennas such as Garmin-38. The aim of the repeater is to allow the GPS to be placed outside, exposed to the satellite view, and allow the user to see the data below decks at the navigation station. The gps repeater displays several pages of data pertaining to both the GPS and the boat electrical system on LCD display. A DB-9 jack is on the front panel for ...
