Ivan Kuleshov ☛ Raspberry Pi 5 Peltier cooler
I delidded Raspberry Pi 5 CPU and made a custom cooling system with thermal tubes and Peltier element.
In theory, it is possible to reach sub-zero temperatures.

Raspberry Pi ☛ Build your own handheld ZX Spectrum with Raspberry Pi Pico
Ken off of the excellent YouTube channel What’s Ken Making isn’t quite over having to spend his childhood in the US where Clive Sinclair’s ZX Spectrum wasn’t available. Fast forward quite a few years, and Ken now has enough bits and pieces in his workshop to make pretty much any computer he damn well wants. Well, he can emulate any computer, anyway.

Raspberry Pi ☛ Get ready for Mission Space Lab with our new simulation tool
Astro Pi Mission Space Lab has a brand-new format and we've new resources to support teams and mentors, and a special tool to help teams test their programs.

Chad Whitacre ☛ A couple of weeks ago I posted about reproduction Commodore 64C motherboards. Two things I didn’t mention were availability and price. I’m thankful we can get them at all, but these points were still glaring omissions with hindsight.
Using the US Inflation Calculator, prices in today’s money roughly correspond to $470 at the low end, and $1879 at launch. That’s still lower than I expected, and proves just how aggressive Commodore were able to punch out these machines at scale.

Remy Van Elst ☛ Fixing the hiss on my Atgames Legends Pinball Micro including root access
It is a ~~small Linux computer~~, I mean, it is a bartop model virtual pinball machine. Real arcade buttons, a back glass screen with scores, 50 built in pinball tables and more available for sale. Did I mention it's a Linux computer? Here's a screenshot of me having root access on firmware 5.69: [...]

Jeff Geerling ☛ When did Raspberry Pi get so expensive?
Well, I bought all the parts required to build a Pi 5 to the same spec—including the adapters and parts to assemble it into one small unit—and it turns out... the Pi is more expensive. And slower.
The Pi 4 still starts at $35 (for a 1 GB model), but the Pi 5 starts at $60 (for 4 GB) and climbs to $80 for the maximum 8 GB model.
But if you want to use an NVMe SSD, add on $20 for a HAT to adapt the new PCIe jack to an M.2 slot. And to power it, you need a $12 5v 5A power adapter (though the slightly-cheaper 3A adapter works in most circumstances). And throw in a $7 Active Cooler since the fan included with the official Pi case won't fit if you add an M.2 HAT to the top. Plus, you probably need a $5 micro HDMI to HDMI adapter if you want to plug the Pi into a monitor.

Purism ☛ Purism Liberty Phone to be Featured in Orpheum Films Collaboration
Todd Weaver, Founder & CEO of Purism stated: “After hearing the interest from David and team at Orpheum Films and learning the story of ‘Legionario’ which sounds like quite a gripping story of universal redemption, I was excited to have Purism collaborate by providing product and any assistance required to help tell the story effectively. Additionally, David and Eric Cummings share a creative and entrepreneurial spirit, which drew some parallels to the early days of Purism, crowdfunding to launch a project (in their case an international feature film completely independently), plus loans and investments to iterate their vision along, persevering through struggles as they get closer and closer to their dream, these parallels reminded me of our own quest of creating the first phone with Made in USA Electronics. I am excited to pull in the power of the Purism team and Liberty Phone and Librem 14 into this feature film, I am excited to collaborate with David and Eric and believe they have a great career ahead of them.”
