Server migration before server migration (#E14)

Quick update post: My all-time favourite hoster Uberspace veeery recently announced that the entire U6 generation of their servers will be moved to a different data center this very evening, as the old one will be torn down. Wan Hung Lo was hosted on those. Starting time about 8 o’clock in the evening local time, downtime probably four to eight hours in total, but servers are moved in smaller batches.

With two hours notice I decided to upgrade to the U7 server generation which everybody will be forced to until the end of the year (EOS of CentOS6 with EOM by Uberspace). […]

Kalorik JU1400 comparison (WHL #60F1)

Just a minor comparison post as I’m in the mood to clean up my place and take things apart. An intent that usually only achieves one of those things, as taking apart stuff makes a larger mess than just the original thing sitting somewhere…

This is (well, was, but it’s not broken in a destructive teardown, just taken apart so that it theoretically could be reassembled) the vacuum cleaner that I think my mom bought without asking in September 2007 when I was about to start studying. Clearly got less use than the family vacuum of similar vintage, just due to the sheer size difference of the places, let alone I did not friggen vacuum every week. […]

Sport exhaust pop and crackle of a…Dirt Devil M2881-0 vacuum cleaner? (WHL #60)

Someone had fun. With the old crap that everyone technical gets for free when visiting family. This time: An old vacuum cleaner, probably close to ten years old. Described to me as “makes weird noises, shut off immediately” (sure). Oh, and of course it was someone else that used the thing when it went from fully working to probably defective. Aah, family.

Plugged it in at home and had a giggle:

People spend thousands of Euros to make their shitty cars even more ridiculous, and here’s my extremely low riding Dirt Devil asphyxiating on pop and crackle noises :lol:

Alright, further disassembly just reduces weight and didn’t uncover anything stuck inside. […]

Thermalright True Spirit 120 Rev. A BW 4U fan mount rebuild (#P29)

Technically the second step to the Fujitsu Esprimo board modification in #P28, but not necessary for regular ATX cases that are just big enough to fit a tower cooler, especially nowadays. Well, I always got special problems with my special builds, so I needed to address that.

With the Intel board mount, the Thermalright True Spirit 120 sits ever so slightly higher up in the case compared to the AMD one. It not only interferes with the card holder which is fixed by drilling two more holes in it, but the appended fan holder also touches the case lid. […]

Dental Impression Mixing Dispensing Gun Universal Dispenser Gun 1:1 /1:2 Silicon Rubber Dispenser Gun 10:1 50ml Dentist Tools (WHL #59)

Some filler content (ha, pun intended) for THAT time of the year. I want my beloved winter back, and I want it to last all year round. Fuck that …intergluteal cleft sweat.

So what do we have today? A 2K epoxy dispenser gun. I bought this to test (and use) some 10 epoxy cartridges that randomly appeared at work – nobody uses this type, nobody even has a dispenser for it (we only have 2:1 and 4:1 glues, no 10:1), and it was expired like a year ago. As it is hard to justify buying an original dispenser gun for the extreme rip-off price of like 70€ for glue that is likely not even usable, I kindly disposed of the cartridges, bought the dispenser with my own money, and had a shot. […]

Fujitsu Esprimo E920 D3222-A12 12V/11Vsb to ATX conversion (#P28)

Recent hardware acquisition: Parts of an Esprimo E920 system (board, CPU, RAM and power supply) for replacing my main desktop system, a good old FX-6300 with 970 chipset board.

Why would I post about this? Well, it’s not a drop-in replacement. DIY required, since those OEM things always have some custom oddities. In this case it’s two (and a half) of them:

  1. Power supply has no ATX mounting bracket
  2. Power supply and board are not -12V/3V3/5V/5Vsb/12V units but 11Vsb/12V only
  3. Board has no I/O shield, just fitting case cutouts

Note that there are datasheets of this very Fujitsu board out there that show a regular ATX connector with all the standard voltages required. […]

High Speed 4 Ports LED USB 3.0 HUB With On/Off Switch Power Adapter USB Hub For Desktop Laptop and the CAT S61 (WHL #58)

This post is filed under “old, forgotten crap that has issues with recently added hardware”.

Well, this might be the new record holder for ancient reviews – but only due to recent events. I bought this USB 3.0 hub for 3.59€ with free shipping back in July 2017 (pricing hasn’t changed all that much). It was a purchase following up the 3+1 Gigabit/LAN adapter described in WHL #34. I still run this thing to support four USB3 keystone modules that are roughly 2.5m away from the mainboard. That’s not only difficult for the USB signalling at the highest speed setting, but also a strain when running high power devices such as 2.5″ hard drives or a mobile phone that needs a bit of juice. […]

ESP32 hardware faders (#P27)

Maybe my google-fu is rusty, or there’s simply no full example of this on the Interwebs…that’s pretty strange.

This is about the cherished ESP32 that will feature an extension/replacement of my #P7 series. This was an ESP8266 board that replaced a dumb lighting control, offering sensor logging to a database. I quickly found out that the limited pin count (and quirks) of the ESP8266 would require me to think about e.g. shift register extensions to make the entire project viable – which now got replaced with the large ESP32 that does have all the flexibility that I need. […]

USB ISO multiboot script – Ventoy (#P26)

Speaking of the GitHubs on the Interwebs: I’ve been using a somewhat selfmade bash script to make bootable USB media for quite some time now. It’s capable of running ISO files directly from the USB drive and also the option for a separate partition for some Windows WIM extraction, in order to offer bootable Windows install media. As I’m the only user and there’s not that much demand for running different Linuxes at the moment, that script is badly maintained and only got an update when like a new Ubuntu LTS hit the market. […]

Netgear EX6120 OpenWrt support (#P25)

Looks like I missed a post last week…ah well, here it is.
From the bunch of defective hardware that I bought back in March there’s still some repaired access points left. One of the hobbyists that was interested in some EX3700 APs asked about the EX6120 that are more abundant, faster, and not much more expensive. He’s going to revamp his WiFi and wanted some OpenWrt mesh. Well…back then the hardware compatibility list said it was somewhat compatible, because both are closely related and the EX3700 has support. The EX6120 firmware was linked to the EX3700. […]
