AAAAH FIBER!!! After four years of pestering AT&T, it is finally here! (And I can finally join the NTP Pool... eventually, it'll be a video of course!)

If you're at VCF Midwest, come all the way to the back corner and check out my NTP Time demo on a bunch of old Macs! (Starring an Xserve G5 with an acrylic cover). Also check out Mr. Macintosh's rack full 'o Xserves across the pod! #vcfmw

I'm outta time! I'm packing for VCF Midwest today, but did finish up the last three projects for my NTP Time demo on old Macs: Xserve G5, Mac SE/30, and iBook G3 Clamshell (over AirPort Wi-Fi!). #vcfmw Also a bonus look at AppleTalk-based time transfer: www.youtube.com/watch?v=h3RW...

Everyone out here talking about Apple's new phones. I'm just interested in their design labs running a Raspberry Pi CM4-based resin printer, front and center in this shot lol

I restomodded a 1995 GPS Time & Frequency Server, and learned wire wrapping, a little GPS history, and how to avoid the Telstra back-to-2006 bug. Video: www.youtube.com/watch?v=CivR...

Wire wrapping is neat. Never tried it before, but now I have and I love it for prototyping! (And no that is not AI-generated, somehow the physics of wire wrapping results in these beautiful little towers of gas-tight low-resistance connections!)

A little Mac SE/30 surgery leading up to #VCFMW 21! <2 weeks remaining until VCF Midwest 😬

Guess what I'm installing in this 1995 GPS Time Server?

Every once in a while a mini rack pops up in the build showcase that makes my jaw drop a bit... this is the first horizontal-layout mini rack that I've seen, and the aesthetic reminds me of some NASA-esque cleanroom computer. Source: github.com/geerlingguy/...

Tomorrow is Micro Center's Columbus OH Grand Re-opening, and they invited me to come. Just stopped in earlier to scope it out. So much better organized for maker parts, they have practically everything from @adafruit.com to @pimoroni.com neatly racked!

Pine64 is the latest company I've heard that's pausing any kind of SBC development or releases for the time being: www.hackster.io/news/pine64-... I wasn't kidding when I said the hobbyist SBC market is dying (www.jeffgeerling.com/blog/2026/dr...)

Welp. Glad I bought a few 2/4 TB NVMe two years ago. Not going to be happy the day one of them dies!

I'm ready for a good time—but maybe not the best time. Guess what just showed up today?! Ben Eater's new clock: eater.net/clock (excited to see the rest of his series roll out...)

This was packed in 1" thick foam with bubble wrap and in a baggie, in a solid box. Not sure how so many components got popped off!

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: www.youtube.com/watch?v=8WzA... Thanks to @idlehandsdev.bsky.social 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: www.youtube.com/watch?v=ziPI...

Oliver Ettlin's PTP Wallclock project just got a huge upgrade; he's been adding all the features I asked for, and then some! Now it has a fancy web UI and tons of display settings :)

Jeff Geerling @jeffgeerling.com · 14/07/2026

I completely forgot to mention.... I'm going to be at @opensaucelive.bsky.social this weekend! My theme will be time—if you have a neat time-based project, please tell me about it. I'll be on the lookout for clocks, counters, syntonization, and synchronization :)

Last week I flew a 20 TB hard drive up to Canada 🇨🇦, to see if I could outrun the Internet. And I did! But I also got to help @idlehandsdev.bsky.social set up a new 45Drives server, and we had a special guest show up to help via CRT! Watch here: www.youtube.com/watch?v=v0DE...

Can you spot the ad integration? 😆 I'm fine with people skipping (i even add chapter markers for it). Time is valuable and if you don't want to sit through an ad read, it's no skin off my back.

One day we noticed a burning smell in the oven. It had code 'F2' and turned a batch of muffins into charcoal... Because GE respected my right to repair my own appliance, I was able to debug and fix it! Quick 2nd channel video on it: www.youtube.com/watch?v=Vrjs...

IP KVMs are incredibly handy—and inherently risky. I tested over 20 of them over the past couple years. One of them even got me an FBI visit ;) Today's video covers *all* of them: www.youtube.com/watch?v=4wYx...

Jeff Geerling @jeffgeerling.com · 31/05/2026

Anyone else hyped for Open Sauce? Despite the topic of my last video, it was awesome to see maker- and repair- friendly companies like Framework represented. Plus the many, many inspirational projects demoed by the community! Early bird tickets: www.opensauce.com/tickets

Can you receive FM radio on a 3D printer's heatbed? @repkord.bsky.social asked, and we tested, with some assistance from my Dad, a radio engineer! The answer is yes, and a video is here: www.youtube.com/watch?v=BA3_...

Just printed this TashTalk USB to LocalTalk adapter enclosure for networking vintage Macs with modern computers (through an emulation layer). Used Polar Filament's Retro Platinum PLA, printed on a Prusa Core One+ (had a little issue sticking to the textured build plate)

One of these things is not like the others... (see 2nd pic) Fun to finally have a reliable setup for measuring ±1 ns PPS (and a solid Rubidium reference) among all my clocks! Adding another clock every few days... and probably no video on this stuff for months!

HomePod minis are 6 years old, but I learned something new today: how they work in stereo pairs. It's not magic, it's just good time! Check out my video poking the HomePods with Wireguard to discover their secret: www.youtube.com/watch?v=9h-n...

Getting full remote control set up for each of them too, but still trying to figure out how to get them to power on remotely...

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: www.youtube.com/watch?v=AjmK...

Finally sorted through the entire Pile of DDR2 testing on Xserve. Only 8 sticks of 17 worked. Was that generation of RAM cursed or something? I didn't use desktop RAM from around the PC133 era up to DDR4, so having these sticks with giant heatsinks is a little alarming :P

Coolest tech I found at #NAB today — 8-channel TV tuner ATSC 3.0 card from SiliconDust; for control over PCIe uses an RP2350 (4x UARTs)z Got to talk to Nick Kelsey (President/CTO) about it!

Always hard to keep my Dad from touching AM towers. Here he's acting like he's bridging the ball gap (lightning protection) on KENO-AM tower base in Las Vegas, NV (we were touring the site at the end of NAB day 2, thanks to Kintronics and the station engineers!)
