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.

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.

RFID Treasure Chest for LARP
I built a treasure chest which opens if a riddle is solved. To prove that the riddle is solved, the players need to put the correct three RFID/NFC tokens (out of several tokens to choose from) onto three RFID readers in the correct order. If they fail too often, a curse is uttered! In this post I describe the hardware selection, the electronics, the assembly and the software.
Root shell on a MStar based UMC TV (Sharp LC-24CFG6132EM)
Not being happy with a few things on my Sharp LC-24CFG6132EM smart TV, I decided to dig deeper, hoping to find ways to reconfigure some settings. While I not achieved that goal yet, I at least managed to gain root access to the Linux running on the TV. Since the TV set is based on a MStar product, I suspect that my procedure will work for any MStar based TV, at least those manufactured by UMC, which for Europe own the brands of Sharp and Blaupunkt. So here I document the procedure.

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.

TARDIS housing for my Raspberry Pi media center
When I built my media center, it went into a simple black box:
