Here I was, hoping for a good time today.
Home assistant 13 years old! 🎂 Happy birthday to us! Home Assistant is officially a teenager. 13 years old today 🥳🏠 Here’s to the teenage years! 🎉
Apple's considering entering the server market again, with the M8 Ultra. But I found the axed rackmount server Apple was building in the late 90s at VCF Midwest—the ANS 300. Thanks to @ClassicII_MrMac for telling me more about it!

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:

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

Latest little 3D printing life hack: print drafts of new models in white PLA. Easy to scribe, mark up with a pencil, see dimensions in any lighting, etc. So much easier sticking pencil marks on the model than making notes on a sticky.

All these creator monetization programs upping their requirements these days. I can no longer 'monetize' on X (not that it changes what I post here)
APC/Schnieder discontinued their UPS NMC2 in 2022. Rather than upgrade to their proprietary $470 NMC3, NetCube Systems Austria built an open replacement, the OpenNMC. I've been testing one. It's a drop-in upgrade, and it includes NUT! Video here:

Coming to VCF Midwest? If you're like me, it's hard trying to remember where everything is, especially with @vcfmidwest taking up the ENTIRE expo hall this year. So I made this tool last night: Now it's a lot easier to find exhibitors! #vcfmw#

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:

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?
Before NTP there were Time and Daytime:
I needed a mini mobile homelab setup for VCF Midwest, and I've never used UniFi gear before. Thus I built this tiny homelab network rack, that fits in my carry-on luggage:
