RE: mastodon.social/@danyork/1159066152… Happy 40th to the #IETF! I enjoyed 15 years of my career with the IETF, traveling the world, making friends, publishing Internet-Drafts and RFCs. 😁

I enjoyed watching on YouTube Patrick Wood as the Keynote Speaker at the AMSAT-UK 2025 annual colloquium this morning. He did live demonstrations of his CubeSat Simulators which was awesome! www.youtube.com/live/RC1p6iS-zwE?si… […] [Original post on mastodon.radio]

Had a mild-but-annoying cold all weekend, but worked on some projects. My ‘connect your Morse Key to Discord’ boards are now with JLCPCB for assembly. And I designed a servo controlled ‘analog dial gauge’ for the CubeSatSim project.

A grey 3d printed square snaking style gauge with no value indications on a workbench.

@ku2y Hi! I've been playing with a CubeSatSim that the RSGB have lent me. It's been rather a lot of fun so far. Do you know of anything that can decode the BSPK telemetry that isn't FoxTelem? I'd ideally like to hook it up to MQTT so I can build a visualiser for it. Also I've wired up the INT […]

Coming soon to my web site! In early 1999 #Swatch set out to publicize its new “Swatch .beat Internet Time” by launching #Beatnik, a grapefruit‑size “mini‑Sputnik” #satellite from the Mir space station. The plan was to replay user‑submitted voice clips (each had to include the word *beat*) on […]

The story begins with parts and printing the frame for my first attempt at the AMSAT CubeSatSim #cubesatsim #AMSAT #3dprint

4 grey plastic 3d printed square frames against a wood table background, each about the size of a saucer. The 4 frames are the top/bottom, left, right sides of my cubesatsim project. I haven't removed the scaffolding yet, so it still has some extraneous bits I need to remove/clean up.
