Replacing Fabtotum Hybrid Head v1 Hotend with E3D Lite6

I replaced the stock hotend of the Fabtotum Personal Fabricator Hybrid Head v1 by an E3D Lite6 hotend (The full metal V6 should work the same way). In this post I describe the steps to remove the old hotend, get in the new hotend and the simple modifications to the firmware that were required.

Hiking Maps Follow-Up: Large Area Maps

The approach for creating feature-rich hiking maps described in my earlier post was limited in area, since it uses the Overpass API to download OSM data. The Overpass API has a restriction with regard to the amount of data downloadable in one go. In this post I describe a way to download a much larger area if needed, using the PBF files available from Geofrabrik and processing them with Osmosis.

Le Potato Media Center & German IPTV Re-Revisited

The comment by Argus Nymus on my Media Center for German IPTV post made it clear that my approach with playlist filtering via web proxy was way too overengineered. For several reasons I needed to rebuild my media center anyhow, so it was time to simplify my approch, which I describe in some detail here.

Interfacing EasyMeter Q3M via Info-Interface

The installation of my fuel cell heating required a bi-directional power meter. Bonn Netz, my local power network provider, uses meters of type EasyMeter Q3M which have two infrared interfaces: A bidirectional D0 interface, and a read-only info interface. I use the info interface (INFO-DSS) to read out power consumption and production of the three phases. For this, I built an optical interface, a 3D printed housing for it, and use the UART of a Raspberry Pi with python to get the values.

IPv6 in my LAN with Unitymedia, Technicolor TC7200, Ubiquiti EdgeOS on Edgerouter X and Prefix Delegation

This post describes how to set up IPv6 with Edgerouter X (and supposedly any EdgeOS device) in interplay with the infameous Technicolor TC7200 cable modem as provided by Unitymedia in Germany, using prefix delegation to advertise valid IPv6 addresses into the LAN. This guide shows how to configure settings via GUI instead of CLI.

Media Center revisited: Libre Computer “Le Potato” plus LibreELEC

While Raspberry Pi with xbian is already a versatile media center, I’m not 100% satisfied with everything. And, with the advent of H.265/HEVC as German DVB-T2 standard, the technical requirements have outrun the current offerings of the Raspberry Foundation. So I decided to migrate my Kodi media center to brand-new Libre Computer’s Le Potato board with LibreELEC, and here are the steps to do so, starting from the xbian media center described in an earlier blog post.

Interfacing Vitovalor 300-P with a Raspberry Pi

I want to integrate my new Viessmann Vitovalor 300-P fuel cell heating into my home automation. For this, I use the Optolink interface, vcontrold from the openv community, and create my own configuration files from several sources.

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.
