Collection of articles describing various applications for the Raspberry π (in german).

The entire desire to do this came about from reading about building a Stratum 1 clock using a Raspberry PI at http://www.satsignal.eu/ntp/Raspberry-Pi-NTP.html and from the use of a Sony radio clock to provide WWVB pulses from the WWVB receiver module that was used in the radio clock.

However, all of the projects and examples I found used Linux which I did not really want to use. I much preferred to use NetBSD, but it lacked a number of critical features that would be required to make a properly working Stratum 1 clock. Interrupt support for the GPIO pins was needed and adding a PPSAPI driver that could be triggered by a GPIO interrupt would be necessary.

The Cosmic Pi project aims to build the world's largest open source distributed cosmic ray telescope. You can be a part of the project, by becoming a Cosmic Pixel!

GNSS receiver based on ublox MAX-M8Q for the Raspberry π. Other interesting parts such as antennas, filtered pre-amplifiers etc. are available too.

stali is a brand new static linux distribution based on the original pre-2010 plans of the suckless.org project, but with a couple of revised goals:

stali goals
Follow the suckless philosophy
Target x86_64 and arm (RPi) support

piShift makes it super simple to get programming on your Pi Zero – just plug your Pi into your laptop with a micro-USB cable and it appears as a USB Drive. Drag across a .py file, and within seconds the Pi will automatically detect it’s been added, and will start running the most recently edited file.
