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.

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.

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.

Rigol DS1054Z Password Login Problem *Solved*

I use the Rigol DS1054Z as my benchtop oscilloscope now since a few years (the one in my title image), and I am rather happy with it. However, one thing never worked for me (but is of utterly low importance – it was just nagging me): You can access a (very) few scope functions via the web interface when opening http://[IP of the scope]. The network settings section is password protected, and according to e.g. this post on EEVblog the user “rigollan” with password “111111” should work. It never worked for me. Other posts claim that “test” or even “blah” is the correct username, password “111111”. Did not work for me either. This finally worked:

  • Go to http://[IP of the scope]
  • Go to “Security”
  • Enter both as old and new password “111111” and confirm –> Success message appears
  • Now I can log in with any user with four or less letters, among them “test” and “blah”, but also “a” or “1234” works!

Funny…

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.
