Aircraft museum Laatzen and Wunstorf (#E22)

Traveling!
Among many other things, I visited two aircraft museums in the Hannover area, Luftfahrtmuseum Laatzen (south of Hannover), as well as JU52-Halle Wunstorf (north-west). Technically I also passed by a museum dedicated to helicopters, the Hubschraubermuseum Bückeburg, but I effing took too long visiting our colleagues nearby (so…technically also a business trip!), which made me arrive 20 minutes before they closed and they wouldn’t let me in (some do that, even at a reduced rate – probably wanted to go home early).

TOMLOV DM9 Max 10.1″ HD IPS HDMI Digital Microscope 1500X 20MP Coin Microscopio Magnifier Soldering Microscopes For Repairing (WHL #100)

Aah. Looks like #100 is finally here.

So why not spend a hundred bucks and buy something nice? Something that I’ve been thinking about for quite some time now, but with the professional options up in the thousands of Euros, and the cheapo versions (for a tenner, or two) making my skin crawl?

Well, here’s my new digital microscope, a Tomlov brand DM9 Max. Apparently pretty new, only released in the last month or so. Couldn’t even find it on Amazon, eBay or (whoa) a regular shop in Germany, so I ordered directly from Tomlov via AliExpress. […]


Dishonest, scammy AliExpress games – and a towel from drippy dick (#R21)

AliExpress occasionally does have some great promotions, and they’re usually linked to their games in the subpar phone app. Often times, some base promotion is available to everyone, and additional discounts can be gained by game progress. I’m not sure why that is, since advertisement inside the games is limited, shopping is clunky and very limited, and one is generally better off picking items outside of the games. Nowadays I’m just assuming it’s a time waster for western people paid for by the Chinese state, that seems to be the most reasonable explanation of the whole shebang. […]


Refrigerator Odor Eliminator Air Purifier Deodorizer USB O3 Ozone Air Purifier Food Preservation Deodorizing Fridge Freshener (WHL #99)

Ozone generators – the heroes of fart neutralization :D
(or something along those lines…)

I recently got a portable ozone generator that is powered from a single 18650 lithium cell, at a whopping 6.39€ from AliExpress. I already own two of the units BigClive once described as “Twinkies“, due to the fact he recommended this style of unit because of its circuitry. Unfortunately I ordered the wrong ones with 4x AA battery supply instead of a 18650 cell – it wasn’t clear in the description and I couldn’t be bothered as the units were 4.82€ back in late 2021. […]


Tecknet TK-WD004 doorbell 230V AC to USB conversion (WHL #98)

A while back, the landlords decided to toss the old doorbell system. It was fine for ringing, but the audio part was troublesome (50Hz hum of some transformer supply), plus the physical call buttons were mashed multiple times by some brutes and beyond repair. I never used the phone system, it’s just two meters away from the actual front door. The landlords also didn’t bother, because opening the actual door (plus their apartment door) can’t be done electrically, so someone still needs to dash down. It’s a bit of a granny flat situation, so live on ground level and they take up the rest of the building. […]


Improved OpenSCAD battery holder script (BigClive) (WHL #97)

A while back, BigClive used to share OpenSCAD snippets in a lot of his DIY videos, allowing viewers to print (and modify) things that he figured out for the specific video. One of those was the battery holder script, a simple array of square-packed cylinders that were hollowed out from one side, in order to, well, hold things like batteries, or hex bits, or screwdrivers, or …

I recently had the urge to store a bunch of batteries in a nice way and began modifying the simple 33-line script. Couple of viewers already suggested changes like center holes, and since OpenSCAD scripts are just plain text, they were able to share their modifications in the comment section. […]


MicroSD speed comparison – genuine cards and a Chinese fake (WHL #96)

Since I don’t want to become the BigClive of the text blogging world, I pretty much have to stop rambling about fake flash drives (NVMe, SATA SSD, USB drives and SD cards) from China. Clive himself knows that too much ozone content makes his audience yawn ;)

So, as Easter (read: the couple holidays around it) is a great opportunity to run some backups and digitally clean up the place, here’s a quick speed test comparison on the history of MicroSD cards. It all started with my troublesome RPi4 having high iostat values all the time, leading to a new card for my laptop backup drive, which in return handed down his MicroSD to the Pi. […]


Brand New Portable SSD 1TB 2TB External Hard Drive Type-C USB 3.0 High-Speed External Storage Hard Disks For Laptops/Desktop/Mac (WHL #95)

AliExpress and their stupid game rules finally made me (inadvertently) buy* something that I heard about at least 13 years ago…a full-sized USB hard disk that only houses a tiny USB stick!

*Ackchyually, that is not quite correct. Like with the NVMe drive of WHL #92 that took me a long time to get refunded (and it only happened via PayPal, since AE to this day strongly believes in returns to fake warehouses in Afghanistan), this one also ended in a dispute and now I get to return it in exchange for a full refund. This time, though, to a warehouse in Germany, so I unfortunately cannot keep it, but now that I know how to find these…

But first things first, this is the fake USB drive that I remember seeing all over the interwebs:

Funny back then, but it probably consisted of a fully working USB drive, just a very small one compared to the expected HDD. […]


The Ender 5 PlusPlus and some toasty PETG (#E21F5)

Time flies…

Six months and I think 3 spools of matte PLA later, the Ender 5 Plus is now pretty close to shape I want it to be. There’s a fully custom panelized and gridded bottom section now that carries all electronics above and the 230V input below the 80×40/40×40 extrusion layer. There’s an optimized holder system around (left, right, back) for the 60cm LED panels. There’s stiffening triangles on every corner now, except for the front top extrusion that is moved down a couple centimeters so the bed/nozzle is visible during setup. […]


NEW LSI 9300-16i 12Gbps SAS-3 PCIe x8 HBA P16 IT mode ZFS TrueNAS UNRAID (WHL #94)

Here’s a quick and simple one: Cooling advice for 16-port SAS cards.

The LSI 9300-16i cards have gotten surprisingly cheap over the past months. Dirt cheap, in fact. All-16 port SAS cards are traditionally pretty pricey, even though they are “just” two 8-port cards on one PCB. In the past 10, maybe 15 years, there was never a time when buying a 16-port card (used or new) was cheaper than buying two 8s. Sure, sometimes people needed a single-card solution (availability of PCIe slots, PCIe lanes, or space in general), but the usual recommendation for 16-bay chassis like my Supermicro 836 was always to buy 2×8 instead of 1×16.
