Two Minute Teardown: Ubiquiti SFP Wizard
Details are below. but I wanted to put this up at the very top for visibility.
If you have a SFP Wizard running Firmware version 1.0.5, DO NOT update it.
If you have a COPY of the 1.0.5 OTA file, please keep it safe and get in touch with me.

Two Minute Teardown: Hamgeek YK-1000H NTP

Curiosity got the better of me when browsing AliExpress and I spotted this GPS NTP server for under $100 USD.
I needed a cart-stuffer anyways so I ordered one as a backup for my existing GPS/NTP server.
While waiting, I took a look around to see if there was any additional information about who makes this / if there was a custom firmware or similar.
Nope, there there is not a ton of information about the YK-1000H online.
#TwoMinuteTeardown: Duogalia AM70 Optical Fiber Multi-Meter
Two Minute Teardown: Duogalia A-M70 Optical Fiber Multi-Meter

While diagnosing a flakey fiber link, i ran into a situation where a basic “flashing red” visual fault finder was not sufficient. I needed to actually measure the optical power levels on both ends of the link to ensure that the fiber was not damaged and that the SFPs were operating within spec.
This was the cheapest tool that could be delivered quickly. The issue was found and fixed so now let’s have a look inside.
TESmart HKS801-P23-USBK KVM Teardown
TESmart HKS801-P23-USBK KVM Teardown
Recently, one of the USB ports on my previous KVM switch failed. Since it’s a critical piece of equipment, I needed a replacement the same day. The original AliExpress product page was no longer available; the seller seems to have closed up shop entirely.
Fortunately, the OEM—XUFUNG—has released an updated version, now sold in the US as the TESmart HKS801-P23-USBK. It looks visually identical to the previous KVM switch, but the USB ports now feature the characteristic blue color indicating USB 3.0 support.

Two Minute Teardown: Petkit Eversweet Solo 2

I am doing research for an upcoming project and was curious about how other people have solved a similar problem. This happens to be the cheapest option that was available at the time.
I am primarily interested in the pump; the integrated “low water” sensor and the UV-C sterilization are very nice features that would check off a lot of boxes for me… Unfortunately this pump it lacks both the flow rate and the head that I need for my project.
