Tesla Model S Grounding Stud (#P52)

*IT Crowd emergency services voice* Has this…ever happened to you?

Well, probably not, nobody is driving old Tesla Model S’es. If however you do, and you get a sudden influx of weird and wonderful warnings that include the following, this blog post might help you out.

  • frunk sensor suddenly shouts at you with MCU_u005_FrunkOpen, despite the frunk clearly being closed correctly – starts off with sub-second warnings that can barely be read on the screen, progresses to super-annoying intermittent contact where it beeps at you every second for a new event, up to full failure where the fault can be ignored once via button and then just persists
  • low beams (Xenon) on passenger side are out, including a BC_W006_rightHeadLightFail warning about their malfunction – in advanced stages also the Xenon high beams might be unavailable and the LED daytime running lights may flicker or are off entirely
  • horn isn’t working anymore, silent (ha!)

Business Card scanning grid, scanning script, and some AI-supported post-processing (#P51)

Looks like we got another case of a DIY solution that competes with existing hardware. This time, it’s from my current quest of tidying up the rooms, especially in terms of old paper documents. Over the last 2 to 3 months, I have been scanning like a man madman and accumulated over 11000 pages plus quite a bunch more in terms of deduplication, e.g. realizing my main broker does still store ALL documents ever generated. Once fetched from their servers (in packets of 20 PDFs each…click click click), those replace printed documents right away, since my physical copies, either printed myself or sent by them via snail mail, are the exact same as the PDF – and those files are of course much smaller, labelled in a somewhat useful fashion, with proper original file dates, and at least partially searchable.

Poor man’s compliance testing: The EnderEMC (#P50)

Such a bold title, such vague blog post – I recently had the pleasure of comparing two very different systems for EMC pre-testing at the lab bench, and one of them gave me an idea.
The two systems were a

  • Y.I.C Technologies EMScanner / EMScanner+ / EMScannerR / EMScannerR+ (with an additional capital R, whatever SEO marketing genius came up with THAT idea), which is a base plate that has all of the signal pickup coils already integrated. Advantage being a fast scan since there’s no moving parts – with the drawback that the raster is fixed in X/Y but also Z direction, and the DUT more often than not needs to be placed upside down onto it.

Failed repair attempt on a BSH dishwasher 9000 683 387 power board (TNY264GN) (#P49)

Here’s something unusual for today: A failed repair attempt. Well, the patient is technically alive again, but very very sick and needs replacement. But he’s currently in a working state as a proof-of-concept

This PCB is from a work colleague, it’s not from my dishwasher. The “MELECS 9000 683 387” branded power board seems to be a major failure point in some BSH appliances (Bosch, Siemens, Gaggenau, Neff, Constructa, maybe even Thermador, Balay, Pitsos and Profilo if these sub-brands of BSH sell dishwashers, I didn’t check).

A little trip to Spain, for an “X” (#E27)

Unsurprising to everyone, my travel preparations were actually preparations for a road trip. And while there is no deeper meaning to the main target destination itself, it took me quite a while to get there (not using a straight line) and to get back afterwards (even more not using a straight line). And that’s not a good thing to announce to the world when the home address is just one click away ;)

Well, main objective was to visit the Tesla Supercharger at Xinzo de Limia, Spain, since that is (currently) the only supercharger in the world outside of China that starts with an “X”. […]

PMK GRUPO – Kofferraum Organizer Auto Zubehör | Auto Organizer Kofferraumtasche Wasserfest Faltbar und Verstellbar – Orange (WHL #116)

Super quick update from my quest of finding a suitable car trunk organizer: I got a pair of “PMK GRUPO” branded units, and while I very much doubt the claim of them being waterproof, I think I might settle with these and add reinforced plastic bags or similar storage as needed during the trip.

That’s the one (mostly marketing images for today!) – bought for 13.95€ a piece in orange, also available in gray and purple for that price, or one Euro cheaper in all black. Currently the colored ones are on Black Friday sale at 9.95€ – and the Black one isn’t

Anyway, sizing works reasonably well for a Tesla Model S trunk, two of these connected with the latches on their short sides do fit the entire trunk width with ~5cm spacing in between. […]

K KNODEL Kofferraum Organizer, klappbarer Kofferraum-Speicher, Automobilkonsolen und Organizer, Kofferraumspeicherorganizer mit verstärkten Griffe (Mittelgroß, Schwarz) (T021-A) (WHL #115)

While we’re at the somewhat non-technical side of things, let’s quickly talk about trunk (boot) organizers. My old Model S has a spacious trunk at around 750 liters, plus 900 liters with folded back seats, plus another 150 liters in the frunk. Drawbacks include a slight necking at the back seats where the wheel well protrudes; at that point, the trunk width is only 95 to 100cm, compared to up to 140cm at the very end. It’s also a hatchback, which means general access is super easy, but with the aerodynamic tear-drop shape, it’s not that tall for the most part. […]

USB-Kabeltester USB-C-Kabeltester, Datenkabeltester Prüfplatine für USB-C, USB-A, Micro Mini Lightning-Kabel (WHL #114)

Simple test gear, this time from Amazon instead of AliExpress. A USB cable tester that sat around for well over a year – and was absolutely worth the money once I needed to use it.

First things first, I bought this back in February of 2024 on Amazon Germany, as AliExpress didn’t have the exact model available back then, for whatever reason. Seller was Treedix UK, shipping via Amazon, and with some other bits and pieces the order exceeded the free shipping threshold, so I only paid the 15.49€ for the item and no additional shipping cost.

Qbrick System PRO Toolcase foam inlay (WHL #113)

Back after a short training week for work in Köln, and some additional 2000km all over the Ruhr area, the Netherlands, and some B-roads in Belgium. While I prepared videos for my Beach Buggy channel, I simply was too lazy to do the same here, oops :)

Today’s post is about a small box from the Qbrick system (https://www.qbricksystem.com), specifically the toolcase from their “Pro” lineup. We have one of their larger boxes at work for 3D printer filament storage under low-humidity conditions, as recommended by a coworker. The large boxes are really sturdy, and, if one has the space, are genuinely worth their price. […]

VEVOR Drill Bits Sharpener 3-13mm Portable Sharpening Angle Grinder Mill Grinder Sharpener with 11 Collets For Factory Workshop (WHL #112)

As indicated lately, my drill bit sharpener journey hasn’t ended with the two diamond wheels that I got for free, but instead I bought a more serious tool. Sure, as always, there are way better devices out that can also handle smaller, or bigger, or specialized drills – but I think this one is more than decent for non-commercial use and surely oversized for what I usually do. It’s easy enough to operate every now and then without reading the manual again (and crashing the first drill inserted), and while it could be smaller and lighter, it’s probably is on the lower end of what a durable sharpener has to weigh in order to survive years and decades unfazed.
