PIC16F877 APRS Weather Station
Weather Station is PIC16F877A based and has a 4x20 LCD, a data logger output and accepts 1Wire wind instrument. It has a built-in APRS TNC. Connect it to your portable rig thru a DIN5 connector and you have a true portable weather station.
1Wire weather station is a simple way to build your weather station. It has USB and RS232 interfaces.
Included on this board are Motorola Pressure, 1 wire Temp. & Honeywell Humidity sensors. An interface socket (RJ11) for 1WIRE wind instrument completes the weather station board.
Weather station may be connected to your PC/Internet and do not require any processor. It doesn't have an LCD display. This station may be used with 1Wire LCD Display Unit to display weather data on LCD or connects directly to your PC for weather data publication on internet.

Build your own LC Meter and start making your own coils and inductors. This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils. LC Meter can measure inductances starting from 10nH - 1000nH, 1uH - 1000uH, 1mH - 100mH and capacitances from 0.1pF up to 900nF. The circuit includes an auto ranging and "Zero Out" function to make sure the readings are as accurate as possible ... [more] |
