Connect Nextcloud and MS Teams

As Head of IT for a medium sized company it is my duty to make data and the internally used software reliable, trustfull and accessible to all of the companies employees. The usage and development of Open Source Software is therefore vital to keep control over the data which the company is using and producing. I am therefore proud to announce that we have decided to support Mr. Dirk Riehle and Nextcloud with the AMOS Project. The aim of this specific project is to develop Open Source Software through students together with partners of the industry. In our case roughly...

Chiptunes / Bit-music Archive

If you are into chiptunes (that old computergame music) I recommend checking out the Mod Archive: https://modarchive.org/ It’s a compilation a of different Mods and XMs (Files in which the 8-bit-tunes come) which can be downloaded and then be played with FastTracker (available on https://16-bits.org/ft2.php) or the XMP Xmod-Player under Android. On Fedora check out MilkyTracker

Data-Experiment “Made to measure”

This is a documentary about an art-project. The artists wanted to show how someones life could be reconstructed by only analyzing the data stored in the persons google-profile without ever meeting or talking to the person. Thrilling: https://www.ardmediathek.de/video/wdr-dok/made-to-measure-ein-datenexperiment/wdr-fernsehen/Y3JpZDovL3dkci5kZS9CZWl0cmFnLWYwZGQwNTgwLWMyNDUtNGIwZC1iNjE5LTljY2YwNDM5NmVhMQ/

Freifunk@Filmfestival LU

I assume it couldnt handle more than 30 clients at once. The next time i will set up a separate router with Freifunk Software and a sector-antenna. We will see how that goes 😉

Raspi BabyCam v2

On my first babycam I used a usb-webcam, LXDE, chrome and Jitsi to get the video signal to the receiver. I needed to replace the camera and decided to buy a used raspberry pi cam (v1.3). I also printed a case for the cam but this turned the camera upside down and the jitsi picture too. While you could turn the picture with: I also was a little disturbed with the high resource consumption of the desktop and especially the jitsi session inside chrome. The pi got hot (ca. 80 degrees C) so i needed to install a fan to...

3D printing with Ender3, Octoprint and Cura

Hi, in order to print my own PhonieBox Figurines (and out of the desire to make some experiments) i decided to buy a good and cheap 3D-Printer. After reading an testarticle about 3D Printers on Heise.de I decided to buy the open source 3D Printer Ender 3 from Creality for roughly 140,- EUR from 3DPrima. This video shows nicely how to assemble it: Octoprint So far I am really happy about it. Setting it up was fun and after a while hooked it up to Octoprint. It is an open source software that runs on a raspberry pi allows you...

Pi-Hole on-the-go

My Pi-Hole which is running on a VM has now about 1 million entries in its blocklist. I have all entries whitelisted i need to and now I want to use the pi-hole not only at home but also from my mobile phone. At first i forwarded port 53 (tcp and udp) from my fritzbox cable modem to my turris omnia router to my pi-hole VM. In the mullvad-VPN app (for android) it is possbible to set a custom DNS server. Here I set my static external IP (on which this webserver is running to) and everything worked out fine....
