After you get into ham radio, you stop looking at touristy things and start looking at the antennas on top!

Successful deployment earlier this week, videos on pause for a couple weeks so I can help the other kids get to and fro and prep meals while my wife recovers!
(Though might wrap up the latest Geerling Engineering video since it's 95% done!)
Pi 5 2GB model is $50, has 'D0' chip stepping with 'dark silicon' (unused parts of BCM2712 chip) removed.
I bought a few, and delidded one:
Finally, someone designed a 3D printer for Australians! The Positron V3.2 is a fun, portable printer. I built one and tested off-grid portable 3D printing in my latest video:
More RF testing today... video coming soon :)
RISC-V is going mainstream: see how the Milk-V Jupiter Mini ITX board runs as a normal desktop PC, with Ubuntu, Bianbu, and Fedora Linux!
Ooh, is SSH support coming to Pi Connect soon?
There are still people in my YouTube comments saying it's impossible to buy a Raspberry Pi 5 for under $100.
DigiKey rn:
The LattePanda Mu brings something unique to the SBC/SoM market—x86. Why it matters:
There's a new SBC cluster king: The Turing RK1 is 2x faster than Pi 5, 5x faster than Pi 4, and I test four of them in a new 10" mini rack:
As free money dries up and profits slow, companies slash headcount almost as fast as #opensource community trust.
My thoughts on IBM's HashiCorp buyout:
Totality! #SolarEclipse2024 #TotalSolarEclipse
More to come...
It's Pi Day tomorrow. Are you ready? @npub1tfk5...2ajd is...
Water cooling the #RaspberryPi 5 is... definitely a thing.
Very expensive ($200 for the whole kit), very overkill (42°C at 2.8 GHz overclock after 10 min), but I do like that it exists, even if *very* few people would ever need it. A short review:
Raspberry Pi 5 shortages shouldn't last long — Or at least that's the hope, based on current production rates.

Found at #CES2024 — what do you think it is?
It's my stomaversary! One year ago today I had my ostomy revision.
Thanks especially to the UOAA for supporting me and thousands of other patients every year! (And to all the excellent WOCNs, nurses, GI docs, and surgeons who help patients like me!)
Theme for 2024: more companies start inventing new "open source" licenses that aren't, and try to solve the freeloader problem by making "open source" mean "source available".
Raspberry Pi 5 PCIe reverse engineered schematic, how does it look @npub15xz4...0xzp, @npub1956u...a5zj, etc.? Still waiting for @npub15nnu...sdr0 to release those schematics! :)

There is an alarming number of people who think "cryptography" == "crypto" (as in the currencies and scams).
It's strangely hard to talk about cryptography now without suddenly having a number of people screaming "SCAMMER!"
