Just got one of these - USB-C power analyser. Very helpful in checking what power devices actually use and gave me some surprises when I checked here. Highly recommended! shop.pimoroni.com/products/min...

Cecilia Payne-Gaposchkin figured out what stars are made of ✨ Also she wasn't believed for a while, but then a man independently made the same finding 🤷‍♀️ I wrote a short profile of her for @sciencenews.bsky.social celebrating her PhD thesis, which set an impossible bar for all theses to come:

It's Day 100 - something to be excited about?

The #moon as seen from #Edinburgh with my Google Pixel 10 Pro camera. x10 x30 and two at x100. Suspect some AI processing in the x30, and the X100 shows bot "unprocessed" and AI "final" images. Exposure was -1 stop for the images, perhaps not required for the x30 and x100.

Snowing in #Edinburgh now.

Disappointed not to see #BBC carrying the #BoatRace today.

Join BGS geologists on a guided walk of Arthur's Seat, looking at the unique geology of this extinct, ancient volcano. Spaces are limited, so book now! www.eventbrite.co.uk/e/arthurs-se...

A couple of interesting projects in this months RadCom - a magloop wireless antenna tuner & a review of the TinyGTC frequency counter review.

For all you #Meshtastic and #MeshCore enthusiasts - here are a couple of plots I made of an ASACOM cavity filter for 868 MHz I recently bought from AliExpress. Just meets its specs. I had hoped to see more than 50 dB out-out-band rejection, though.
