  I thought I had the best time at the largest vintage computing event in the world. But then someone rolled up with a cesium atomic clock, and I was no longer sure... My video covering VCF Midwest is here: https://www.youtube.com/watch?v=oW-Hp8-DAB0 #vcfmw

  My Spectrum Business Internet connection goes down weekly. I finally set OPNsense up so I can swap to a borrowed cell backup connection. Blog post here: https://jeffgeerling.com/blog/2026/opnsense-backup-internet-gateway/ But if you have backup 5G Internet, what do you use? (Midwest US)

  I found the cheapest way to add 25 Gbps networking to a Mac. Some 3D printing required... Video here: https://www.youtube.com/watch?v=_--JjauL19A

  Finally! Proxmox VE officially supports Arm. At least the more server-grade Arm platforms. I tested it on my Ampere Altra Max 128-core workstation, and it runs there (though I did hit a couple hiccups). See: https://www.youtube.com/watch?v=Lg263L1W97w

  Today I test the $699 Dell XPS 13, and see how it compares to the MacBook Neo. I didn't realize it would have a more efficient CPU, upgradeable storage, or run Linux as well as it did... It's not flawless, but it's a good budget laptop. Video here: https://www.youtube.com/watch?v=A2B7oI0FYqo

  The Pi 5 16GB was never a good deal. But at $300+, it's just... don't buy it. Luckily, Pi 4s still start at $35 and Pi 5s at $45. And the 4GB Pi 400 is somehow $50 at Micro Center. Video with more: https://www.youtube.com/watch?v=53AkaYvw63U

  I got to test a Pixel Pump 2 (by Robins Tools) for my 2nd SMD PCB. I just used it for manual pick 'n place; it's a solid little bit of kit if you do this stuff often. Video here: https://youtube.com/watch?v=8WzAy72yCJA Thanks to @idlehandsdev for putting me in touch!

  A man with a watch knows what time it is. A man with two watches is never sure. So now I have three GNSS PPS watches. And I can measure UTC to within 20-40ns. Just need my entire forearm. Not done yet: portable rubidium atomic clock for holdover.

  I had the best time at Open Sauce—and I can prove it! (At least within ±1µs...). Full video here: https://www.youtube.com/watch?v=ziPIbxoFc_g

  From my research, Reolink was supposed to be one of the best local-friendly cam companies... Strike 1: I can't set up my new Reolink camera without the App initially (web UI disabled by default). Strike 2: Can't add RTSP user even in app, so I have to use admin for RTSP?!

  QuadRF is a phased array antenna that can see WiFi through walls, spot drones in the sky... and it's powered by a Pi 5 and FPGA board. Very neat device, we have a full video up on Geerling Engineering: https://www.youtube.com/watch?v=QESevE2c_cc

  What's that saying... 'If buying isn't owning...' Sony deletes another large stash of movies off users' accounts after users "purchased" the movies. Cue up the "I'm tired boss" meme https://www.youtube.com/watch?v=l19tXQcw2tE

  I tested WisdPi's 10G Ethernet Expansion Card for Framework computers. Good news: It can hit 9.4 Gbps, in certain scenarios. And it'll be < $100. Bad news: It uses USB-C and that means the combinations where it'll hit full speed are limited 🥲 https://www.youtube.com/watch?v=fMXT6mEPR0Q

  Bambu Lab 3D printers: never again. They're breaking the open source social contract (for the nth time...), and I'm past hoping they'll amend their ways. https://www.youtube.com/watch?v=eb48MdtNaDQ

  55th anniversary of the 555 going strong, with a Big Clive livestream (https://www.youtube.com/watch?v=jzNjFJdaw_I), and a video precisely 5:55 long published at 5:55 on 5-5 from @eevblog - https://www.eevblog.com/forum/blog/eevblog-1746-the-555-is-55-years-old!/

  It has taken far too long to get to this point. But it's also pretty cool having three fully functional Xserves running! (None booted when I got them)

  I didn't beat a bunch of college students with my new SBC cluster, but it still performed admirably. In today's video, I tested the DeskPi Super4C in a new mini rack from Waveshare. Check it out: https://www.youtube.com/watch?v=AjmKpDNsTa8

  One of the strangest Pi clusters I've ever seen... happens to be a commercial success, but most people looking at this box would never know it has 3 Pis inside! Video here: https://youtube.com/watch?v=GYN7TH5y1CM

  This 10 Gbps USB-C adapter is under $100, tiny, and fast—check out the new generation of 10 GbE NICs in my video. If you need faster Ethernet, this may be the ticket! https://www.youtube.com/watch?v=zYZbZJZfCFI

  Raspberry Pi Connect might soon get a Windows server app, so you could control both Pis and Windows PCs through Pi Connect! https://forums.raspberrypi.com/viewtopic.php?t=397786

  Every month it seems like another YT channel I follow in tech replaces the human voice backing videos with a cloned AI voice. Makes me wonder at what point in the past they went all-in on generated scripts. (It's not all bad, if someone is still at the helm who actually cares. But overall quality declines.)
