The 2022 Royal Edinburgh Military Tattoo and another useless FLIR video (#R16)

Do I rant too much? I probably do.

Is it unfounded? Probably not.

So, I’ve done a slightly insane yet enjoyable trip to Scotland and covered 2000 miles in 8.5 days, thanks to the wonders of free lifetime supercharging on my Tesla. End point of the trip was the Royal Edinburgh Military Tattoo show on 25th of September, for which getting a single ticket on the desired “7” block was a bit tricky, but worked out in the end. And while literally hundreds of the crowd of around 9000 people had their phones up quite a lot of the time (does anyone watch those hour long videos of wobbly footage?), […]


100W Aluminum Power Metal Shell Case Wirewound Resistor ±5% 0.1R 0.5R 1R 2R 6R 8R 10R 20R 100R 1K ohm Aluminium Shell Resistor – Dummy load project (WHL #56)

Something very basic for today: Resistors. Yaay. :lol:

I was tasked with troubleshooting a Blu-Ray player that cut the sound a few minutes into movies repeatedly. Sounds like a thermal issue to me, and after the local electronics shop grabbed 35 bucks for an “inspection”, yielding a “motherboard issue” which makes this Samsung heap of sh.. a total loss, it was given to me for a last look into it, before it was tossed. Of course the owner would never buy a Samsung player again, as this high-end model played Blu-Rays just fine, but does refuse to do so with double-layer DVDs, which his previous Samsung DVD player was absolutely capable of.

99 LEDs E27 Flame Lamps 9W 85-265V 4 Modes Ampoule LED Flame Effect Light Bulb Flickering Emulation Fire Light Yellow/Blue Flame (WHL #53)

For a quick feasibility check for a work project I somewhat recently (end of September) ordered a pair of E27 “flame” lamps. 4.35€ each including shipping, one of each available color – yellow-ish (very warm white) and blue (being a company color).

Big Clive demonstrated these a while back and I had hoped for a bit more oomph. Hence I bought the 9W version. Which turned out to be 9 China-Watts. Well, not even that, which is disappointing and kicked these out of consideration. Too bad, my colleagues liked the effect quite a bit, but it’s clearly too dim for any ambient lighting in larger spaces. […]


CITYSAX 160Ah LiFeYPO4 battery discharge and teardown (WHL #51)

Speaking of electric cars: A colleague recently bought a used electric car and (obviously!) contacted me in order to diagnose/troubleshoot it. Sadly he was able to sell it for a profit before we got it fully fixed, so no live data recordings, no power/torque graphs, no nothing to show here. But he left me a dead cell for which he got a replacement from the seller right away, as the traction battery had voltage dips under load that indicated (at least) one damaged cell.

If servicing individual battery cells sounds a bit strange for a modern electric car, that’s because we’re talking about a CITYSAX from a company that is conveniently named the same. […]
