A new image!

We have just released a new image for the owners of our Cosmic Pi V1.5 detectors. If you are having issues with your detector, such as the graphs not displaying, or trouble connecting to the Cosmic Pi Wi-Fi network then this image should resolve these problems.

 

What’s new?

DHCP (Dynamic Host Configuration Protocol) service is fixed, so the Cosmic Pi can assign client devices (your smart phone or laptop) an IP address for wireless communication.

If you have not done anything to your unit since it was shipped to you, we strongly advise you to upgrade to the new software.

 

How to upgrade?

Firstly you should download our new image from here https://www.dropbox.com/s/m8uu5ygjzub4cqy/CosmicExpander.zip?dl=0 (it is approximately 2GB so this may take a while depending upon your internet connection). Whilst it is downloading, unplug your Cosmic Pi from it’s power source. Remove the two screws from the underside of the unit and gently remove the top part of the case. Be careful as the top and bottom halves are attached by two sensitive micro-coaxial cables! When you have opened the device, you will see the microSD card installed in the Raspberry Pi Zero W. Remove the card and insert it into a suitable SD card reader (you may need a microSD to SD card converter). You should then follow the instructions for flashing the image file to an SD card here:

https://www.raspberrypi.org/documentation/installation/installing-images/

When the flashing is completed, eject the SD card, re-install it in the Raspberry Pi Zero W, carefully close up your unit (being careful not to trap the micro-coaxial cables in the joints!) and replace the screws. When you power up your unit you will see the Cosmic Pi Wi-Fi network appear. If you wish to connect it to the internet you will need to connect via SSH (credentials for username and password are on the rear of your unit) and run the command ‘sudo raspi-config’ to access the Wi-Fi configuration menu.

What’s next?

We are still working on future improvements for the interface which will include a packaging system for easier installation/upgrades and better performance when rendering graphics and images. We are also working on some infrastructure to collect all the data produced by Cosmic Pi units connected to the internet. In the meantime, you can connect an MQTT client to our server at cosmicpidata.mooo.com and see all the cosmic rays as they arrive.
