Overclocking the Pi4

Lately one of the POE HATs fan failed and it took a while to source spare parts for repair. In the meantime I noticed that the Raspberry Pi was running stable right below 60°C on full load. Thanks to the…

Removing the M$ repository

You might have noticed the discussion about that Microsoft repository which the Raspberry Foundation has added – without any notice – to their Raspian OS. The vscode repo adds a Visual Studio Code Editor to Raspian – directly from Microsofts…

Power consumption

All the Rasbperry Pi Nodes are equipped with Waveshare PoE HATs. The PoE HATs fans are enabled manually since the auto RPM control by software depending on the Raspberry Pi CPU temperature is not working correctly on Raspian 64Bit OS.…

K3S Base Installation

Within in the last years buzzwords like container platforms and cloud computing with Amazon AWS got more and more hyped. Docker might propably the first framework which comes in mind when you are thinking about containers. And then there is…

Cluster preparations

The Raspberry Pi4 are now up and running. Now there is some customizing needed before we can start settting up the kubernetes cluster. First a member of a cluster a called node. Each kubernetes cluster has a master node which…

Raspberry preparations

Now we are ready to setup and prepare the Raspberrys for Cluster operation mode. So what do we need? In order to take advantage of the 8 GB of Ram on the Pi we need an OS which is capable…

Cluster Housings

As I wrote before it es difficult to find the right case for the BOINC Cluster. There are lots of options on the market regarding those cases. The Waveshare PoE HATs with their GPIO extension are limiting the choices of…

Shipments have arrived

Finally all orders have arrived. Raspberrys and Heatsinks had to be sourced different than the Ubiquiti switch and mircoSD cards. Luckily someone just started distribution of Waveshare PoE HATs here in Germany. So those did not need to ship around…

Hardware considerations

So let’s try to build a BOINC Kubernetes Cluster on Raspberry Pi 4 Computers. What do we need for that? All Rasperry Pi 4 Model B Computers come along with a ARM Cortex A72 CPU (4 Cores), onboard Gigabit Ethernet,…
