CY UC-022-0.9M USB 3.1 Type-C Female to USB 2.0 A Male Cable (90cm) (Rant #R1)

Oooh, look at that precious hellspawn!

“USB-C to USB 2.0 Data Cable for Macbook Tablet, Mobile Phone – Black” – capturing everything that is wrong with USB-C!

Sure, carrying over the perfectly fine USB 3.0 spec into USB 3.1 and calling it “Gen 1” (in contrast to “USB 3.1 Gen 2” that is double the speed) is a huge fuckup on its own. There’s no better way to screw up a customer by allowing manufacturers to call something USB 3.1 compliant (new! shiny!) when it’s just 3.0 with a new badge. […]


USB 2.0 4-Port Aluminum Hubs … and Chinese manual labour (WHL #20)

Hey :)

For today’s blog post I have something that I found at work yesterday. It’s a plain old USB 2.0 hub in an aluminium case, which is used inside of our measuring equipment. Just a jellybean part, it’s sold as Logilink here but I bet other brands just slap on a different logo on the front and they’re good to go. We chose this because it is relatively small, has all USB jacks flat in line (the smaller ones have 2×2 configuration or tend to stack them), and can make use of external power supplies, rather than sucking too much from the uplink port.

USB detector 3.0 High voltage 4 bit OLED QC 2.0 Digital detector voltmeter ammeter voltage current power capacity tester meter (WHL #17)

New at Wan Hung Lo:

…wait, what?

(I’m pretty sure you’ll be able to find my address if you want to, just making it a little harder for google to index it as an image…)

So, what is it actually? Sure, it’s the USB power meter from the blog title. Who would have thought!
Bloody kids with USB 3 toys! Back in my days, we had…umm, good old RS-232 :lol:

I bought this one month ago at AliExpress for 8,61€ including shipping. As you can see, they decided to use some tracked mailing instead of the “ah, no worries” cheapo variant. […]


USB 3.0 Type A Male to Type A Male M-M Coupler Adapter Gender Changer Connector Pro New (WHL #16)

…also sold as Blue USB 3.0 A Male to Male Extension Converter Adapter USB Connector Gender Changer Coupler For Pc Laptop and tons of other variations.

Remember the USB 3.0 keystone module from WHL #13? Yep, it can get worse than that.

I’ve always kept USB gender changers handy to connect weird and wonderful combinations of devices, including measurement contraptions e.g. for current tests. With the advent of USB 3.0 (with classic A plugs, I don’t have any USB type-C devices yet), I needed to slowly upgrade my gear to do such measurements in USB 3 mode. […]


Micro USB V8 Cable 2016 High Quality New Arrival Nice Black White Colors USB Car Charger (WHL #15)

Hello again!

Today, I have something springy for you. A powerful car charger for two of your favourite electronics!

…except I broke it during first use :lol: Prepare for some Wan Hung Lo qualitty goodness!

I bought this fine piece of equipment for 2.48€ at AliExpress back in November. And I got my money back.

Notice something? Well…the center pin looks a bit…retracted. But first things first. As I have a matching car receptacle to test such things with lab equipment instead of doing measurements in the car, I first tried the charger at my lab power supply. […]


Keystone USB 3.0 A Female To Female Jack Module Adapter Converter Power Socket (WHL #13)

My new desk has some extension cables running underneath to provide data and also power conveniently on one end. I decided to use a 19″ 1U “KeyStone” patch panel because I like the variety and modular nature of these adapters. Well, things like HDMI (or even this DisplayPort voodoo!) are hard to find in China, and 4mm banana plug keystones and audio jacks are basically the same price over here. But USB seems very common – so why not buy an USB 3.0 keystone from the Wan Hung Lo factory?

So I did. This arrived not too long ago:

The front dimensions are standardized to 15x17mm. […]
