Supermicro Case and Rails (#P6)

Supermicro – the case manufacturer of choice for people with money. :lol:

This is not so much about Wan Hung Lo price ranged products, but rather about construction techniques. And it’s not even about “we made it this way because it’s the cheapest” – it’s about design that yields the most profit for the manufacturer. Vendor lock-in and all that stuff.

Well, I’m more of a Chenbro guy for reasons that I’ll explain in a bit, but I recently did a classic Dave Jones dumpster dive (with permission), from which I got not one, but four Supermicro cases. […]

Fake Akasa PCIe 6pin to ATX12V 8pin adapter (WHL #41)

Ah well, we haven’t been to adapterland for quite a while, have we? :roll:

I do have more pressing things to do as of now, but whatever. I bought an adapter cable for my new server setup at home, as basically all SFX PSUs with moderate wattage (sub-500, 600W?) do not offer more than one 4+4-Pin or 8-pin ATX12V/EPS12V power plug. Well, why should they, that’s not what they usually need to have. But most server boards, especially dual and quad processor boards, do “require” 2×8-Pin auxiliary power. On the contrary, there is no powerful GPU in that system, so the 6/8-Pin PCIe power cable would flap around in the breeze. […]

Mini-Type Self-Adjustable Six Mandrel Ratchet HSC8 6-6 Crimper Plier For Wire Terminal Connector 0.25-6mm2 Multi Hand Tools (WHL #40)

Software stuff aside, back to hardware. And by hardware, I actually mean hardware. Tools. Let’s check out some crimping pliers for wire ferrules. Automatik-Aderendhülsenpresszangen, as we Germans like to say. :lol:

The unit in review was bought late February on AliExpress for 14.94€ including shipping (which took only around two weeks). When I showed it at work, I needed to order another one with the same specifications (14.89€ in early April, delivery took 3 weeks) and one with four mandrels, but 10mm² capability (HSC8 family as well, 12.13€ mid-March, two weeks). […]

Let’s Encrypt! (#E7)

Just added a SSL/TLS certificate to the site, which once again is a breeze due to the very helpful commandline tools of my hoster uberspace. Works for me, at the moment, so let’s see how much stuff breaks in WordPress over the next few days and months. What could possibly go wrong :grin:

(Yes, I know HTTP logins aren’t state of the art, but why serve HTTPS to literally a thousand spammer accounts that never ever managed to sign in? Waiting for the first one to actually pass…) […]

Mini PCIe Module QCA9880 WPEA-352ACN 802.11AC Dual Band Wireless WiFi network card support Linux (WHL #39)

While I’m in the “X doesn’t do Y, so let’s hotchpotch DIY something to get Z running” mindset, let’s release something else that I’m slightly bitter about. WiFi network cards. [scroll down to the first image to skip my rambly introduction]

I’m not a big fan of Intel for their business practices, but when it comes to Consumer/Prosumer network cards, Intel is basically the brand to get. I’m running a CT Gigabit (82574L) addon card in my AMD ZFS server, and my old Thinkpad has something similar (82567LM) built in. […]

Theme Font & Size Changer for Thunderbird (#E6) [update 64.3 #2]

[You’re late to the party. This crap has been fixed and is now available as addon directly from Mozilla. Click here for the addon announcement, or read the comments on this page for a secondary fix (64.4) for TB58+.]

You know what really grinds my gears? MORONS that “maintain” a piece of software.

This guy called Baris Derin has quite a lot of Mozilla (FF/TB) addons out there. Great stuff. I’ve been using the font changer for quite some time, as my Thunderbird looks a bit odd with default settings. So, what’s wrong with it? […]

Waveshare 400×300 4.2″ three-color SPI E-Ink / E-Paper display module (WHL #38)

Bit of an upmarket item for today, not the usual Wan Hung Lo…had the honour to make that thing display some demo content for a side project at work. So…why not take some photos, publish the code, and get ahold of a similar unit for use at home?

So this is an e-Paper / e-Ink display, actually a module that consists of the display unit itself and a base PCB that takes the flimsy flat-flex connector, adds some passives and presents a more sturdy interface to the microcontroller that will be handling the thing. Also, the PCB is large enough to offer mount points on each corner. […]
