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.

Quick Note: Modify the WordPress Comments Cookie Consent in an Update-stable Way
It always bothered me that I could not modify the text (“Save my name, email, and website in this browser for the next time I comment.”) of the cookie consent checkbox in the WordPress comments section to explicitly mention that it uses cookies.

Floating Table of Contents
I wanted to have a floating table of contents for my posts, but could not find any free plugin that allowed me to do so. Using a combination of plugins, I created a floating TOC myself, which is not perfect, but good enough.
Modified Housing for Alber e-motion M25 Remote Control
For a relative that’s paraplegic, I modified the housing of the remote control for the electric wheelchair wheels Alber e-motion M25 to make the usage easier. Mainly, the small housing was made thicker and larger for better handling. Also, one knob was moved to a different position.
The project is not very sophisticated, but I publish it anyhow – perhaps some other handicapped person can benefit from it.

Convert Window/Door Sensor to Handle Sensor
In order to prevent my venetian window blinds to go down on timer in front of my open window-style terrace door, potentially locking me out, I needed to know if the door handle was in the “open” position. However, I did not want to use a battery powered radio sensor, but the existing door open/close magnetic sensor in the door frame. Here’s my solution.

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.
Legal EPG Scraper for ARD TV Stations to Use With tvheadend External XMLTV Grabber
I wrote a Python EPG scraper for the EPG data of the German TV stations broadcast by ARD. It is legal for private use. Here I share the code and my thoughts behind it.
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.

Case for MP1584 Based Step-Down Converter Board with USB Port
This post is to share my self-made 3D printed housing for a 5V USB voltage converter. Since the used converter board is quite common, I guess others may profit from this design.

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.
