@ExtKits what material are those walls? Looks like a good idea for project photos.

Playing with a Raspberry Pi 5, 4MB RAM. It’s been a few years since I looked at the Pi — my old one is a v2. These have come a very long way.

Reorganizing my home office & added a new switch to provide PoE and SFP. The latter is for steaming I/Q samples from mast-mounted SDRs for local processing. POE is for desktop IP phone (SPA525G) & SBC hacking.

Quite happy with this low-cost Linksys so far. 1990s me with a 10BASE2 net connected to a dial up modem would be astonished.

@ada Just struck me that this is the first photo I've seen of a woman beyond Earth's orbit.

Experimenting with 3D printed DIN rail mounts for projects. The attachment brackets are from open source hw projects, as are the WAGO & RS25 brackets. The PCB & vertical mount brackets are customized (to be published soon). I’ll adopt some kind of hole pattern standard for my own PCBs to simplify things. Possibly 20x20mm grid?

The lines are not parallel, green line on the map is "zero" declination. You can see nice curved blue lines from Eastern US to South America, which the signals follow. I suspect this is marginal from the PNW, according to that map.

Transequatorial propagation (TEP) on 6m is strong today. It follows Earth's magnetic field lines for certain distances across the equator for complex reasons, allowing N/S America or JPN/AUS communication on VHF at times.
