The MetaClockClock78:
gemini://tilde.club/~ghalfacree/202605/20260504-clock.gmi
And finally, Erich Styger's back with another MetaClockClock - this time using 78 clock faces to display the time, animations, or text.
Or why not connect two together over RS-485? (Maybe because building 'em takes three months and costs $1,500 in parts?)
I'm very much loving how many cyberdecks/writerdecks/terminals I'm seeing that use actual honest-to-goodness CRT displays - like this one, which is built around a Samsung tube salvaged from a dead portable TV.
Y'know those little photoresistors? The ones that change resistance according to ambient light? Well... that's a camera sensor, right? A single-pixel camera sensor?
Well, here's a camera built around that idea. It works, if you're patient enough: you're looking at around eight hours for a single exposure(!)
Oh, and the image is "developed" in a spreadsheet, because why not at this point?
Another Altoids tin project, next - and this time it's a fully-functional #RaspberryPi terminal, complete with neato (if slow) electrophoretic ePaper display and internal battery.
It's a bank holiday here in the UK, so you know what that means!
Absolutely nothing, 'cos I'm freelance!
First up on #Hackster today: there are "counterfeit" #RaspberryPi 5 boards in the market, likely bought as 1GB models and upgraded to 4GB/8GB/16GB using out-of-spec and/or low-quality parts.
Raspberry Pi says buy from official resellers only, and you'll be fine.
Also! #Hackster's looking at getting me to do more video (boo), starting with one op-ed piece a month. Could be short-form portrait for the socials, could be long-form landscape - it's up to me.
If you've any ideas of things you think you could stand to watch me drone on about, I'm open to suggestions!
Want to read those ad- and tracker-free? The #GeminiProtocol awaits.

Copy Fail vulnerability:
gemini://tilde.club/~ghalfacree/202605/20260501-copyfail.gmi
Finally, Copy Fail. Yeah, couldn't leave this one unmentioned: local privilege escalation vulnerability in Linux kernels stretching back nine years, most likely including the one you're using now. (Yes, even if you're on Windows, if you've got WSL installed. Mac users, feel free to engage smug mode now.)
Two-line mitigation included, while you await a patch.
8086YES! is back, and this time it's a no to 8086: the BOOK II is a TTL-based Apple II clone with a whole bunch of upgrades including a Z80 SoftCard for CP/M goodness... in a netbook-like (chunky) laptop chassis.
Not going to lie, I'm kinda tempted.
