Where next? I had a barely working 6502 prototype system on my workbench. It was a little unstable and didn’t like being moved, but it did work and demonstrated to me that the concept was viable. Initially I didn’t know … Continue reading
Now its time to look at the rain gauge and wind speed sensors. As far as I can tell, these are just single-bit inputs on the GPIO connector. I don’t know which pins and before I wade through the supplied … Continue reading
The big board that the Raspberry Pi sits on in the prototype weather station I have has an on-board 2-channel MCP3426 analog to digital converter. One channel is used to read the air quality sensor, the other reads the wind … Continue reading
Following on from the weather station wiringPi page… So I’ve had a thought on the one-wire temperature sensor…. 1-Wire is a well defined system and works well on the Pi, however wiringPi has a “pin” based system, so how about … Continue reading
After setting up and testing some of the hardware in part 1, its now time to add the devices into wiringPi. As in part 1, I’m writing this as I go, to give you an idea of my thoughts and … Continue reading
The Raspberry Pi Weather station is a hardware and software system designed by the Raspberry Pi Foundation designed to let schools, etc. record their local weather. The system was produced in conjunction with Oracle who are providing a centralised database … Continue reading
From the Wikipedia entry: The Little Man Computer (LMC) is an instructional model of a computer, created by Dr. Stuart Madnick in 1965. The LMC is generally used to teach students, because it models a simple von Neumann architecture computer … Continue reading
