Not-so random thoughts on LSI HBAs again (#P34F1)

A couple months ago I scraped on the surface of the topic of LSI debranding/crossflashing. Now’s a good time to visit that again, since I got another branded LSI card that I wanted free of the manufacturers old firmware and the “hey look at meeee, I’m a veeeery special controller” look in any device tree. Yes, we know you’re special, but the annoying kind of special. You’ve likely been the default card in tens of thousands of servers or the only (supported) choice people had when opting for external SAS. […]


Pre-Facelift Tesla Model S LED number plate lights real-world testing (WHL #70F1)

We all know who was too busy last week to upload something, and then too lazy to fix that during the entire week…

Well, here’s a very quick but conclusive report about the exchanged number plate lighting on my car. It’s not just brighter by eye or as viewed by the camera, it’s also that much brighter to anything out there swarming around at night that somebody, I do not know their name or preferred pronouns, decided to set up shop just between number plate and lights.

Pre-Facelift Tesla Model S LED number plate lights (WHL #70)

It’s time for cheap lights on expensive cars because of the friggen 3G mobile phone network. Yeah, that sounds perfectly alright.

Two weeks ago I ordered the MCU2 upgrade for my 2015 Tesla Model S at the Service Center Frankfurt. Ever since the possibility for that retrofit was announced by St. Elon, I lusted after it, yet of course it only was made available in the alternative Elon Time™ dimension on time and was delayed forever for everyone else, especially for AP1 cars like mine. Some day in between the recall bombshell of the MCU1 dropped and Tesla extended warranty of that part to 100k miles / 160Mm or 8 years max, and some months later the price for MCU1 cars was reduced from 2500€ (inclusive VAT) to 1550€ (same), as those do not need the AP3 computer refresh.

DIY Chip Quik style desoldering alloy (#P37)

And finally closure on the fake China solder wire topic back from WHL #68 / WHL #68F1. I bought a bunch of Bismuth metal in early June (1KG Bismuth Metal Ingot 99.99% Pure Crystal Fr Making Crystals/Fishing Lures – 20.03€ including shipping, before the “no more VAT free imports” EU legislation went into effect) and with the high lead content solder from the other review, I should be able to make some low-melting point solder.

First of all, the Bismuth was delivered in a big chunk as advertised, which I did not expect. They are somehow able to split that crystallized cake precisely into pieces of slightly below 1kg and then add in small bits to make exactly 1000g (at 2 cents a gram, they clearly do not give away free stuff). […]


Powerbank 10000mAh mit Solar Ideal für Outdoor und Reisen alle Geräte – USB (WHL #69)

In celebration of product review number 69 I decided to exceed the regular scope and make a full-on video review of this very helpful item, showing its use in a real-world scenario with additional audio commentary available on my second channel. […]


Philips 46PFL8008S/12 to 55PFL8008S/12 screen upgrade (#P36)

Back in #P15, two years ago, I replaced the damaged screen of a Philips 46PFL8008S/12 Ambilight TV with a working one from a braindead unit. Classic failure mode of this generation, ideal opportunity for a 2-to-1 repair.
This week I’m going to upgrade the screen from 46″ to 55″. Because I can. And because the wall mount supports the larger unit (which of course I didn’t check beforehand…). And, funnily enough, because I earned ten bucks that way. And because a larger TV is slightly more entertaining in the rare event of watching a movie. […]


The Contorion promise of precision (#R11)

A quick mocking rant to fill this week’s emptiness a little bit – slightly more enjoyable for those that speak German. Since German engineering was/is synonymous to precision and quality, often times really bad fixes caused by lack of time, materials (including tools) and knowledge/amount of residual fucks are ridiculed by linking them to non-precision materials such as expanding foam (“Bauschaum”) and sanitary silicone (“Silikon”). Both are applied in abundance, more is considered better(er), and of course no excess material is removed afterwards. […]


250g-500g 1/0.5mm Lötzinn Lötdraht Löt mit Flussmittel Lötkolben Lötstation DHL (WHL #68F1)

(Follow-up post to the solder test of WHL #68)
While we’re at it – I couldn’t resist testing the flux percentage. Which also resulted in having large samples for a visual comparison. Contrary to my expectations, the lead-free solder wasn’t the one that stood out…

First things first. New batch, same naming scheme as before. Since I already measured weight per meter, I just picked one sample length from a (new) lead-free U1.0 wire and cut the others to expected length. 100cm of that stuff is 5.42(196)g, for comparison. […]


250g-500g 1/0.5mm Lötzinn Lötdraht Löt mit Flussmittel Lötkolben Lötstation DHL (WHL #68)

(Updated, see note at the bottom)
A fancy German item description for today, as I got it second-hand after even a soldering novice noticed this is total BS. “250g-500g 1/0.5mm Solder Solder Wire Solder with Flux Soldering Iron Soldering Station DHL” would be the closest translation. It’s solder – fake Wan Hung Lo leaded solder. Sold on eBay (probably all over the world), not even super cheap at 14€ a roll (250g, large diameter).

It is labelled “JINHU SOLDER CORE WIRE”, Type CF-10 Model B-1, comes in diameters of 0.3/0.4/0.5/0.6/0.8/1.0/1.2/1.5/2.0/2.3 (not necessarily true) with 2.0% flux (probably also not true), and proudly states “MADE IN CHINA”. […]
