Creating the “Perfect” Hiking Map for Germany and other Countries

In this post I show how to create useful hiking maps by merging OpenStreetMap data with the usually excellent official maps of the cartographic offices of Germany and several other countries. Using MOBAC and Maperitive, a transparent layer containing POIs, landscape features and elevation information is generated from OSM data and then overlayed on the official maps. Also, mapsources for OruxMaps are derived for the various countries.

Using PB6/7 of ATmega328P with Arduino IDE

The Goal For a small project I used the ATmega328P MCU – and then the small project somewhat exploded and I needed more and more I/O-Pins. Suddenly all but the PB6 and PB7 pins were in use, and I needed exactly two more… The Arduino IDE did not offer pin numbers for these pins, since they are used for the crystal oscillator on Arduino. My project however did not rely on ultra precise timing, so the internal oscillator was more than enough, leaving the two pins open for other use, but how to address them? I guess with Atmel Studio this […]

Building a Media Center for German IPTV

The Raspberry Pi with Kodi is a versatile media center. Getting it to work with German IPTV in a stable fashion is however somewhat challenging. In this post I outline the necessary steps to set up a XBian based media center, to make it usable on a rather small SD TV screen, to avoid the 30 minutes offset problem with the public German TV stations, to make the channel mappings stable and to control the media center via IR remote control.

Short Introduction

Hi Internet, since I play around quite a bit with electronics and software, and once in a while something comes out that might be of interest for the rest of the world, I decided to start this blog. You may find here things about Raspberry Pi projects, Media centers, Home automation, Microcontrollers, Photography and a little programming, mainly in Python. The blog will be updated on no particular schedule – whenever I think there’s something to share, you’ll find it here, but don’t be surprised if there is silence for several months. Feel free to send comments on anything! – […]
