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. […]


Sneaked into BigCliveLive (#E13)

As you might have heard already, bigclive(dotcom) is running a separate channel nowadays for live streams such as the occasional Manx Beard Club or the more recent weekly corona streams. It’s called BigCliveLive and I’m obviously subscribed to both of them. Aside from the last two livestreams I’ve watched the entirety of those channels…it should be trivial to find out the total playtime with the very handy youtube_dl tool that I use for all of my YouTube subscriptions, but it’s probably comparable to EEVblog, that is, in the medium to high 100s of hours. […]


Supermicro X9SRW-F small riser mounting adapter (#P24)

More fun with the Supermicro X9SRW (and we’re still not done yet!)

The two X9SRW machines that I got had the same CPU and RAM situation, but one of them was in a 815 (1U) case, and the other one still is in a 825 (2U) one. I scrapped the noisy 815 for my board and allocated the more spacious 825. Fans are not the only thing that differs, though, as the added height also caused Supermicro to exchange the riser card for a different one. While the top riser is just an angled PCIe x8 connector (high up to make room for some heat sinks underneath), the bottom one is a WIO type that distributes 32 lanes in total. […]


Construction fails in networking gear (#R9)

Ah well, I’m too lazy to craft another post dealing with things currently in development – let’s rant instead.

A few weeks ago I bought this huge lot of “failed” networking electronics that finally led to having an 8-port PoE switch at home, which is a nice addition – the MikroTik wAP ac finally runs on PoE as intended, the four ports (2x1G, 2x100M) of the Fritz Box router are no longer overcrowded, I did have a good time repairing two of those switches easily and I didn’t even spend a penny on all that thanks to a few sellable items (plus brownie points for donating quite a few more).
