DustinI've messed around with programmatic graphics to display on a 1.8" TFT panel connected to my Pi Cluster. Each node runs a cronjob of a python script to capture state into a .json file while a master node fetches those json files to then drive the LCD display.I have a writeup for the whole build process of the Pi Cluster I created:<a href="https://codingcipher.wordpress.com/2024/03/17/yet-another-pi-cluster/" rel="nofollow noopener" translate="no" target="_blank">https://codingcipher.wordpress.com/2024/03/17/yet-another-pi-cluster/</a><a href="https://mastodon.social/tags/PiCluster" class="mention hashtag" rel="nofollow noopener" target="_blank">#PiCluster</a> <a href="https://mastodon.social/tags/Python" class="mention hashtag" rel="nofollow noopener" target="_blank">#Python</a> <a href="https://mastodon.social/tags/Ansible" class="mention hashtag" rel="nofollow noopener" target="_blank">#Ansible</a>

get my hands on some Sun SPARC Hardware but aside from making my room hot and noisy there isn't much to justify blowing likely over half a Euro per hour (electricity price: € 0,40/kWh) just to have it

driving a 2011 Ford CVPI-71 with a 11,9l SONNY'S SAR-729 engine for commuting from Leverkusen to Köln when there's ample of affordable, reliable and fast public transport that gets me faster from Opladen to Deutz than it takes to drive up the 15th deck of a parking garage just to find a spot to park that 5,7m long street yacht where one can climb out of it from the doors and not the trunk!</li></ul>And that's just bottom-billing, low-cost ARM SoC tech designed for a price tag (to the point that until the <a href="https://infosec.space/tags/Pi5" class="mention hashtag"

DustinMessing around with programmatic graphics to display on a 1.8" TFT display connected to my Pi Cluster. The is not a whole lot of pixel real estate to display much, but I think I've got the basics down.Pink - current CPU temperature Orange - CPU utilization graph (span is about 30 minutes) Blue - Memory utilization graph (span is about 30 minutes)Each node runs a python script from a cronjob. The master node uses ansible to fetch all the data JSON files.<a href="https://geekdom.social/tags/PiCluster" class="mention hashtag" rel="nofollow noopener" target="_blank">#PiCluster</a> <a href="https://geekdom.social/tags/Python" class="mention hashtag" rel="nofollow noopener" target="_blank">#Python</a> <a href="https://geekdom.social/tags/Ansible" class="mention hashtag" rel="nofollow noopener" target="_blank">#Ansible</a>

matt 🦕<a href="https://mastodon.social/@rpilocator" class="u-url mention" rel="nofollow noopener" target="_blank">@rpilocator</a> Though of course a <a href="https://mastodon.social/tags/PiCluster" class="mention hashtag" rel="nofollow noopener" target="_blank">#PiCluster</a> wouldn't be complete without a <a href="https://mastodon.social/tags/3DPrinted" class="mention hashtag" rel="nofollow noopener" target="_blank">#3DPrinted</a> case... so I've made a start on that today too. Probably my favourite print to date given that I took a design off thingiverse.com and remixed it using tinkercad.com.

matt 🦕Today i'm mostly getting a couple more Pi's added to the <a href="https://mastodon.social/tags/PiCluster" class="mention hashtag" rel="nofollow noopener" target="_blank">#PiCluster</a> I've decided on one main Pi4 (as they're basically golddust at this point, props to <a href="https://mastodon.social/@rpilocator" class="u-url mention" rel="nofollow noopener" target="_blank">@rpilocator</a> for the tips tho) and then all the Pi 3Bs that I have around the house will be added as workers, that should give me more than enough. Currently configuring <a href="https://mastodon.social/tags/OMV" class="mention hashtag" rel="nofollow noopener" target="_blank">#OMV</a> to make a start on some simple network storage. The aim is to have all the containers use data on this OMV storage and then I can back that single point up... in theory.
