Getting GPS to work on a Raspberry PI « Peter Mount's Blog One of the tasks I want to use a Raspberry PI for is to take over the duties of an existing ITX based linux box running my weather station. Now in theory that should be pretty simple as the current setup uses pywws to connect to the station and as that’s written in python it should work. Now the Raspberry PI has no onboard Real time clock – which means it needs to use an NTP server to get the time when it starts. Usually you would use the default settings and allow the PI to connect to thenet for it’s time. As the other projects I have lined up for it is to connect my Meade LX200GPS telescope to the local network or to work with my (in prototype) radio telescopes so having an accurate clock is going to be required. Now the obvious solution here is to use GPS as a time source. So this article shows how to use A GPS receiver with the Rasperry PI – although these instructions are not specific to the PI. The hardware Raspberry PI with the A73KF GPS receiver plugged in Plug it in and run lsusb

Tulio Muniz.org LED Series Resistor Calculator All LEDs require some form of current limiting. Connecting an LED directly to the power supply will burn it out in a heartbeat. Overdriving, even briefly, will significantly reduce it's life and light output. Fortunately, driving a single or a string of low current (20-30 mA) LEDs is a simple task - adding a small resistor in series is the easiest and cheapest way to limit the current. Our LED calculator will help you determine the value of the current limiting series resistor when driving a single or an array of low-current LEDs. The program will draw a small schematic, display the calculated resistance and will tell you the value and color code of the nearest lower and higher standard resistor. Input fields Supply voltage: Type in a voltage greater than the LED voltage drop for a single LED circuit and parallel connection or the sum of all voltage drops when connecting multiple LEDs in series. LED current: Type in the single LED current in milliamperes. How to interpret the results
