The Gigatron is a TTL computer and when I first heard about it, I thought that with that name, I had to get one… … and there it is. https://gigatron.io/ So what is it? It’s the brainchild of Marcel van … Continue reading

I said I’d leave the hard parts to last – well, even with these done, we’re not done yet, but it’s time to tackle the rain fall and wind speed sensors. These are slightly different from the others in that … Continue reading
At this point I have a little “main” program that sits in a loop reading most of the sensors and simply printing them to the screen. I’ve created an individual little file for each sensor and given them names – … Continue reading
Now it’s a matter of plumbing it all together. I have created a Makefile – by copying an existing one and changing it (I used the one from the gpio program because it’s similar) then I took the weather.c program … Continue reading
The story so-far… In the beginning the universe was created… Then after a while came weather with the inhabitants of a little blue-green planet having a great interest in this weather – presumably because there was so much of it… … 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
