Two years ago, Linus Sebastian released a general purpose ratcheting screwdriver tailored towards PC building and IT needs. I reviewed the LTT Screwdriver, and found it to be a good tool that did improve a couple things where it counted: the ratchet mechanism was useful for a broad range of lighter tasks, and the in-handle bit storage was a creative improvement over the patented MegaPro Automotive design the LTT Screwdriver was based on.

The price of the LTT Screwdriver was about $15-20 more than I think it's worth, but it's still a good enough driver you can justify paying extra. I bought three LTT Screwdrivers and have one on each of my workbenches at home and at the studio!

I test servers on a temporary basis a lot, and many enterprise servers don't have as user-friendly external port indications, or little OLED displays to provide useful information. They're no-frills because they don't need frills, you just deploy them and they run for years.

I often need to gain access to the server's IPMI/BMC interface to manage the server remotely, and it's not always obvious what IP address is assigned if you don't manually assign one via your router and a MAC address.

I could scan my network for the IP address, but assuming I have the server booted and it's a modern Supermicro or other standard system, I can use ipmitool to grab the BMC IP:

Despite what it looks like, this isn't a hot-rod Apple Watch. This is an IP KVM. What does that mean? It's basically a remote control rocket pack for any computer, from a giant tower PC, to a little mini PC you might run in your homelab.

It's called JetKVM, and the team behind it sent me two to test out.

BIG SCARY DISCLAIMER: The JetKVM is currently on Kickstarter. If you decide to back it, and they don't deliver, that's... actually pretty common. I did back their Kickstarter, and I think they'll deliver, but there are no guarantees.

BuildJet did not pay for this post, and I am not sharing in any profit, or even using an affiliate link. I just saw this tiny KVM come across my feed, thought it looked amazing, and asked if I could test it out.

This afternoon I received the following email from Arrow, regarding the Snapdragon Developer Kit for Windows:

Dear Valued Customer,

Please see this important message from Qualcomm:

”At Qualcomm, we are dedicated to pioneering leading technology and delivering premium experiences to our valued customers. The launch of 30+ Snapdragon X-series powered PC's is a testament to our ability to deliver leading technology and the PC industry's desire to move to our next-generation technology. However, the Developer Kit product comprehensively has not met our usual standards of excellence and so we are reaching out to let you know that unfortunately we have made the decision to pause this product and the support of it, indefinitely.

Meshtastic—a simple off-grid mesh network used to transfer short messages—is a neat bit of tech, but until recently, most development has focused on little nodes with or without tiny OLED displays, and a separate phone app or web UI to actually interact with the mesh.

The major use case I have for Meshtastic is backup comms—when cell networks and physical infrastructure may be unavailable. In those conditions, I don't want to run my full computer, or even a full smartphone, just to communicate long range via text.

Enter the T-Deck:

Today I published a video detailing my testing of three new Raspberry Pi HATs—these HATs all add on PoE+ power and an NVMe SSD slot, though the three go about it in different ways.

You can watch the video for the full story (embedded below), but in this post I'll go through my brief thoughts on all three, and link to a few other options coming on the market as well.
