The worst Android tablet — A quick teardown
Expectations. When buying a cheap device, I don’t expect a display with “Retina” quality, but it should still be usable and not something the engineers who designed it have to be ashamed about. It shouldn’t be a piece of shit … Continue reading
Fire… a friggin’ fire — Well, just lots of smoke really.
When I got home today at about 5pm or so, I smelled the characteristic BBQ smell. Burning wood. Quite A LOT of burning wood. Very odd, or at least very unusual for this neighbourhood. Upon entering the staircase the smell … Continue reading

Shooting in Munich. As of now (2016-07-22 20:12 CET) not much is known about how many were hurt or killed. The media are going crazy. ENOUGH!

Believe whatever you want. But please, make sure it stays inside the head. It’s your own private folly, no need to include everybody else.

A small but helpful upgrade, if you’re into acquiring your own temperature calibration data. At some undetermined time in the future this might be expanded to a full multi-point calibration mode. The config menu was amended with the parameter ‘display_adc_raw’. … Continue reading

The day the Twitter died…
I case you haven’t noticed yet, TWITTER IS DOWN, oh no! First I suspected my friggin’ Android-Tablet, as usual (and rightly so). It is slow and crash-happy, I suspect very poor quality FLASH-memory (IOWAIT is insanely high, fstrim doesn’t do … Continue reading

PBFComics – RESET
2015 — What a year!
The year twenty-fifteen has had a lot in stock for me and my family, both near and far. There was death, illness, strenuous recovery, unexpected relapse, and much other crap nobody really wants nor needs. “A bit much” you could … Continue reading
Insidious back-stabbing planned obsolescence — SNAFU

YOUYUE 858D+ hotair station — BLDC Fan-speed mod
