MikroTik wAP ac door jamb bracket (#P16)

$ThingsIWantedToDoForALongTimeButDidntUntilIPaintedMyLivingRoom++;

When upgrading my laptop to the QCA9880 3x3ac card, I had the need for an 3x3ac access point. I went for the MikroTik wAP ac at the time, my first dedicated AP, as I always was a FritzBox AIO dude. In the card review I said I wasn’t planning on in-depth reviewing the AP, but I still need to scratch a little on the surface here, literally.

The AP is sitting next to the excellent FritzBox 7362SL and in fact is sharing the power supply with it. As the MikroTik is a PoE device, it doesn’t have a fixed input voltage; instead, it’s a 11-57 V wide input (“12W max”). […]


33pcs Security Bit Set with Magnetic Extension Bit Holder Tamper Star Screwdriver Bits Set (WHL #52)

Ever had problems removing second-gen security screws, you know, those with the asymmetrically placed security pin? “No”, you say, these don’t exist?

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. […]
