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.

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

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.

Qi wireless power tester

The Qi standard for transmitting power is ~ 15 years old and has been ubiquitous for at least a decade now. And yet, I have only recently seen any testing equipment for it.

The Wozniak WPX-0001A is a simple tester that can measure the output level and protocol of Qi chargers.
