A tour inside the brand new CSIRO Mobile Mission Control & Operations Centre, built inside a b-double truck. Dr Mark Dunn gives us a tour of the new fitout.
https://research.csiro.au/moc/

Purpose-built, the b-double trailer deploys into a fully operational mission control centre that can accommodate up to 30 mission operators, each supported by configurable multi-monitor stations and mission-status displays. Onboard, satellite, 4G, integrated radio and vibration-tolerant servers ensure connectivity, even in remote locations. The mobile Mission Operations Centre is powered by a battery-backed solar system with generator fallback, enabling sustainable, off-grid operation across Australia's geographically dispersed launch sites.

This is not a full review, it's Mailbag, and is basically me documenting trying to sort out all sorts of issues.

EEVblog 1705 - The World's First Desktop Personal Computer TEARDOWN

Fri, 29 Aug 2025 03:41:48 GMT

The world's first desktop personal computer wasn't the Apple 1 or the Altair 8800. It wasn't even the HP 9100A, it was the Olivetti Programma 101 from 1965! Computer Teardowns don't get much more vintage than this.
