USB 3.0 to 10/100/1000 Gigabit RJ45 Ethernet LAN 1000Mbps Network Adapter (WHL #34)

While I’m at computer peripherals…this one has been laying around for quite some time. Bought in January 2017 for 5.68€ on AliExpress, but current pricing is basically the same. Guess IC prices haven’t dropped much, although laptops that do not carry an ethernet port due to height limitations have become more common. Yeah, bullshit, but Jon Doe likes thin hardware with cooling problems. Always reminds me of the Macbook Air / Thinkpad X300 ad parody…

That aside, I really wanted to compare this Gigabit adapter with the two other types of network interfaces that I have available – some Realtek onboard stuff that I deem “good enough” for everyday use, and some PCIe addon card from Intel that is usually considered worth the upgrade (after all, people still buy sound cards, right?).

Micro usb male to female 1 to 2 Splitter Phone sync data charge Cord Y Splitter (WHL #23)

Uuuh, I’m lazy today. Let’s review an USB cable :mrgreen:

Well, it’s not one of your standard A to B cables. It’s a splitter extension cable for Micro USB, basically violating all USB specs :cool: . I bought it as I’ve been using two phones in parallel for quite a while now – I can’t let go of my N900 with the nice QWERTZ hardware keyboard and full system access, but I’m also running a Galaxy S5 for all that modern Android rubbish (including BLE support for my GoFar). So this cable acts as a Y splitter from Micro USB (female) to two Micro USB males, effectively saving me the standby power (and socket space) of one charger. […]

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. […]

20cm 8″ inch ATX 4 Pin Male to 4Pin Female PC CPU Power Supply Extension Cable Cord Connector Adapter (WHL #14F1 – first follow-up)

Triple-follow-up to the WHL #14 article about the 4-Pin extension cables for desktop computer mainboards.

Since publishing the article, I managed to order two more cables from CHAINA, two different sellers, with very similar product description. At the end of January, both have arrived and have been tested immediately.
Aaand, what do you know, both were the very same make as already shown in #14. Both failed with clouds of smoke when putting 5 amps or more on them, and of course I started disputes for both of them (one pending, one resulted in a quick refund). […]

2016 New 8″ inch ATX 4 Pin Male to 4Pin Female PC CPU Power Supply Extension Cable Cord Connector Adapter 1PC Hot 20cm (WHL #14)

Religious holidays, you gotta love them. Short (pun intended) review today: A plain old power extension cable for your PC, one of the 12V supply cables to the motherboard. I don’t really know why I ordered it back in January, but I guess it was in preparation for upgrading one of the 19″ cases as a gaming rig. Which hasn’t been built yet, because the bloody display manufacturers only ship crappy 3440×1440 displays with ridiculous FreeSync ranges..or even without. In 2016! It’s not rocket science!

So, what do we have? […]

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. […]

DC Jack Powerbuchse Netzteilbuchse Strombuchse IBM Lenovo ThinkPad SL400 (WHL #9)


Today’s item is one that I needed for my smallish light box. I had some makeshift connections when building it, including one with a fixed 65 W (original!) Lenovo laptop power supply who unfortunately had a loose power plug. When I finally had three illuminated sides up (with the stuff from WHL #7), I knew I needed to step up to 90 W or even 135 W power supplies for full brightness. But this time, I wanted a detachable power plug, especially to not kill the power supplies for normal use, but also for convenience (the box is quite large and the supply is too heavy to attach it somewhere). […]

DVI Male to HDMI Female adapter Gold-Plated NEW M F Converter For HDTV LCD IE (WHL #5)

I gotta sneak something in that I need to rant about a little. It’s a good old passive signal adapter – for getting HDMI video signals into a DVI monitor. What could the Wan Hung Lo engineering department or qualitty management possible f :D ck up?

Well, as it turns out, making a nonworking (nonfitting) unit isn’t trivial. You have to use deep knowledge about both signal protocols to make it …not work.

First, let’s talk about HDMI. To make all this copy protection (HDCP) crap work, you better use digital signals only, that is, not only the video is digital, but also the audio channel. […]

New at Wan Hung Lo: Open Source Hardware! Presenting the USB A-to-Micro bridge (WHL #4) (updated)

Oh well, I already announced it’s gonna be fake. But the other way round ;)

A while back, I saw the USB A-to-Micro bridge from youritronics. I already own one of these medium quality USB power meters that display voltage and current in an alternating fashion every few seconds. But complete control over power, data lines and also shielding is new. So I wanted one. In the short comment section however, someone noted that the signal routing probably isn’t the best. I had some spare time after Christmas this year, and I also wanted to test the Platinensammler (PCB aggregator) service from Jakob Kleinen. […]
