I copied that one out of the description. All the timestamps there are corrupted as YouTube measures them in minutes:seconds but @hackaday posted them as hours:minutes (which are off by minutes anyway) starting at 01:56:30. This is the correct one: … “

Chris Bensen on Raspberry Pi and clusters

Posted by jpluimers on 2022/12/29

Oracle’s Pi Supercomputer

Oracle’s Pi Supercomputer ; click on the image for a larger version.

In 2019 ans 2020, [Archive] Chris Bensen and his [Archive] Oracle Groundbreakers team built a really large Raspberry Pi cluster of more than 1k pies, all network booting to become a cluster. It was for instance covered in the [Wayback/Archive] Building the World’s Largest Raspberry Pi Cluster – DZone IoT.

On his [Wayback/Archive] personal blog, he wrote a few posts like [Wayback/Archive] Chris Bensen: Raspberry Pi Overlay Root Filesystem and [Wayback/Archive] Chris Bensen: Get MAC Address for a Pi Cluster.

It made me also bump into [Wayback/Archive] Building the world’s largest Raspberry Pi cluster early 2020,

Since that wast right after the start of my rectum cancer treatment which lasted longer and, because of I got metastases a few months after radiation treatment, required more treatments than anticipated, I put a note in my bog drafts and kind of lost track.

So I was glad that in fall 2021, I bumped into the draft and found an almost year old post [Wayback/Archive] Chris Bensen: All Raspberry Pi Super Computer Posts in One Spot which is an index in all the blog posts and videos that Chris and his team produced on this project.

I then also learned the cluster had been shown on [Wayback/Archive] Oracle OpenWorld 2019, Breakthrough Starts Here and was covered in the [Archive] Top 10 Raspberry Pi Projects of 2019 | Tom’s Hardware (where I got the [Wayback/Archive] Oracle World 2019 having the 1k+ node Raspberry Pi cluster on display picture shown on the right from).

Measuring environmental aircraft noise (Zelfbouw meetstation voor meten vlieghinder.pdf – Google Drive)

Posted by jpluimers on 2022/10/12

I’ll be following this guideline (or maybe by now already have): Zelfbouw meetstation voor meten vlieghinder.pdf (Google Drive)

This is what I needed:

If you do not have a Raspberry Pi, then you can get it from them as a package for EUR 115 (including case, preinstalled microSD-card, charger and WiFi adapter):[Wayback/Archive.is] Raspberry Pi Zusatzkit zum Komplettpaket Lärm (with configuration manual at [Wayback] Anleitung Raspberry.pdf)
