Deutsche Telekom’s All-IP consumer connections hand you SIP credentials for your landline numbers, and you are free to use them with your own equipment. I bought some VoIP desk phones recently and configured our landline with a self-hosted Asterisk PBX on a Raspberry Pi 4 running OpenWrt (see Router).
First off, if you can have a real network cable, use that. As temporary measure I set up a powerline connection between the apartment and basement. Connection speeds vary quite a bit and I wanted to be able to monitor reported network speeds.
peanball everywhere else. Now I’ve registered peanball.net.I’m using omxplayer on the Raspberry Pi for video playback because it utilizes the Raspberry Pi’s hardware video decoding.
Because the front-end is a separate application, I just need to remote control OMX Player to start and stop the video and figure out how far the video has played back already.
In one of my hobby projects I needed to display additional information on top of a running video. The whole project is based on the Raspberry Pi and Python.
This article describes the approach I’ve taken to display arbitrary content over the video with the help of the very flexible (and admittedly awesome) Kivy framework.
I’m working at a software company. One of our side projects is the integration of new control concepts and input devices to robotic control.
We’ve integrated a couple of input devices and can control different rovers. One of them is the one I built.
While browsing for different breakout boards for the Rover I’ve discovered a nice little board that has a push button and logic pin to control a MOSFET.
This little contraption allows switching on and off the power, say through a USB cable.
