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.

Supermicro X9SRW-F Ivy Bridge EP compatibility comparison (#P33)

Some canned content for today – back when making the Supermicro 2011 board fit my needs (#P23,#P24), I stumbled upon the Ivy Bridge thing. Technically, the two rack servers that I got should both be compatible with the E5-2600 series (Sandy Bridge EP), as well as E5-2600v2 series (Ivy Bridge EP). The product website states that “BIOS version 3.0 or above is required” for this to work, and both boards run the most recent version (not that there’s so many versions to choose from). Both had a E5-2630L installed, so SB-EP. […]


3D printed switch repair parts (#P31F1)

Some more details on the Bosch oven repair. These are the replacement parts that I ordered from Sculpteo, which, according to its own website, is the market leader in online ordered printed parts. Sculpteo also happened to be bought by BASF this spring, and they’re mainly printing in France but offer support in German (with offices in Germany, I think). They offer laser cutting as well but charge additional shipping cost for those, which made me skip parts of my order…

The part in question was already featured in WHL #61 (crappy automated model generation) after which I recreated it by hand. […]


Brennenstuhl PM 231E power meter zero reading fix (#P19)

Quick fix today – a colleague recently complained to me about his Brennenstuhl Schuko power meter only reading a static “0.0W” regardless of the load that was connected to it. Display was fine, the outgoing Schuko was fine (we checked with a 2kW space heater), but the unit would display no power usage at all.

As there’s no long tri-wing bits (bastards!) at work, I took the unit home only to discover that my bits are also too short to reach the damn screws. He said he didn’t care and was ready to buy another unit (I kindly recommended the ELV Energy Master Basic 2, which will serve as comparison unit later), so I drilled into the case to widen access a little. […]


Fujitsu P20-2 finalized CCFL to LED conversion (#P9F1)

Canned content, for when I’m busy with stuff that’s not definite yet.

A while back, I tried the CCFL to LED conversion on one of my Fujitsu 20″ monitors. I only had warm white LED strips available at the time, mostly because I no longer require cold white DO STUDY NOW atmosphere at home ;) However piss-yellow doesn’t really shine behind an LCD, so I ordered some cold whites. AliExpress -“2018 New 1m 1200LEDS 2835 SMD LED Strip 24V 1900lm 240LED/M Gold Line LED Ribbon LED Tape Light Cool White Warm White Natura”. 6000K color, 12V, “14-18W”. […]


150W Welding Repair Tool Titanium Plating Lead-Free Solder Pot Adjustable Temperature Tin Furnace with EU plug (WHL #48)

What’s worse than lead-free solder? Lead doped lead-free solder… :roll:

Today’s item is a “500g” solder pot that I bought during the Christmas/annual leave shopping spree mid-December for 12.06 USD including shipping on AliExpress. Prices have even dropped a bit since then.

I’ve always been collecting residue from desoldering stuff as I want to minimize contaminating ordinary trash with lead. Not on a crazy level like the EU tries forcing us to, but if I can avoid PCBs and electronic components getting mixed with domestic waste, I’ll keep them separate. […]


Mini-Type Self-Adjustable Six Mandrel Ratchet HSC8 6-6 Crimper Plier For Wire Terminal Connector 0.25-6mm2 Multi Hand Tools (WHL #40)

Software stuff aside, back to hardware. And by hardware, I actually mean hardware. Tools. Let’s check out some crimping pliers for wire ferrules. Automatik-Aderendhülsenpresszangen, as we Germans like to say. :lol:

The unit in review was bought late February on AliExpress for 14.94€ including shipping (which took only around two weeks). When I showed it at work, I needed to order another one with the same specifications (14.89€ in early April, delivery took 3 weeks) and one with four mandrels, but 10mm² capability (HSC8 family as well, 12.13€ mid-March, two weeks). […]


3590S-2-103L 10K Ohm Rotary Wirewound Precision Potentiometer Pot 10 Turn vs genuine Bourns and Vishay pots (WHL #36)

Visiting the dark side of China today – product piracy.

First things first, I actually bought this item twice from two different sellers on AliExpress. One back in September for 1.07€ and now two more for 0.95€ each in early January, just to be able to kill one during inspection. The seller may be the same (I’ve seen that recently from BME280 sensors, review to come), but the shop name is different. It is intended as replacement for the current adjustment knob on my electronic load, as I am an idiot and during build I set the voltage over the pot not to the two end pins, but to one pin and the wiper. […]


USB 3.0 to 10/100/1000 Gigabit RJ45 Ethernet LAN 1000Mbps Network Adapter (WHL #34)

While I’m at computer peripherals…this one has been laying around for quite some time. Bought in January 2017 for 5.68€ on AliExpress, but current pricing is basically the same. Guess IC prices haven’t dropped much, although laptops that do not carry an ethernet port due to height limitations have become more common. Yeah, bullshit, but Jon Doe likes thin hardware with cooling problems. Always reminds me of the Macbook Air / Thinkpad X300 ad parody…

That aside, I really wanted to compare this Gigabit adapter with the two other types of network interfaces that I have available – some Realtek onboard stuff that I deem “good enough” for everyday use, and some PCIe addon card from Intel that is usually considered worth the upgrade (after all, people still buy sound cards, right?).
