Privatsphäre im Internet

Arguing that you don’t care about the right to privacy because you have nothing to hide is no different than saying you don’t care about free speech because you have nothing to say.

Manch einer fragt sich wie man seinen persönlichen Level an Privatsphäre im Internet verbessern kann. Anbei ist eine kurze Liste einer umfassenden Sammlung nützlicher Ressourcen zur Verbesserung Ihrer Privatsphäre:

Logitech M720 unter Debian Stretch

Just a quick note on how to get the Logitech M720 detected and paired under Debian Stretch.
According to Logitech specs, this mouse uses „smart bluetooth“, meaning it’s a low enery device.
As the mouse was not detected via blueman graphical interface, some steps were neccessary to get the mouse discovered.

First make sure your bluetooth adapter is running properly.
Then install blueman package via apt.

open a shell and start a LE-device scan:
sudo hcitool lescan

this will get the mouse detected in the following scan:

open a second shell and run:
scan on
connect XX:XX:XX:XX:XX:XX


Raspberry Pi 3 Altoids case

I recently got a Raspberry-Pi 3 Model B as a development platform for Internet-Of-Things projects. The very first task was to give it an adequate housing, so I decided to put it into an Altoids tin.

raspi Altoids-tin






tools used:

  • sticky-tape
  • permanent marker
  • opinel no8 carbon steel knife
  • sandpaper

I transfered the shapes and locations of the Pi´s plugs onto the sticky tape via the marker.
The tape was put on the Aldoids tin afterwards and the shape was cut out with the Opinel knife. Although the Opinel did the job quite well maybe I should just use a dremel next time.


raspi-sandingWell, actually it turned out the PCB was a bit too large to fit in the Altoids so I sanded down the edges of the PCB almost up to the screwholes. Of cause you have to pay attention not to destroy any circuits or components.

To isolate the board from the metal case to prevent shortening components I put a plastic card at the bottom of the tin.

Bei den FENDER® FUSE™ kompatiblen Gitarrenverstärkern, z.B. Fender® „Mustang“-Modelle, handelt es sich um sog. Modeling-Amps mit programmierbaren DSPs. Da die FENDER® FUSE™ Software von Haus aus keine komfortable Verwaltung der Sound- und Effekt-Presets bietet habe ich diese Cross-Platform-App für OSX & Windows zum Bearbeiten und Sortieren von Presets geschrieben.
