- Freifunk Luxembourg

• took it over from fantawams
• made a new website
• trying to make everything fancy and nice
• goal: making it more popular

- TLS Expiry Tracker

• TLS is good but many people set it up in non-ideal ways
• show how frequently it goes bad

- Updated and documented Command & Control

• official Ubuntu install was outdated, bloated and broken (e.g. Syngergy software KVM)
  • updating it broke the desktop and ssh shutdown
• tried installing NixOS
  • not enough space
  • broken USB hotplug
• installed Armbian
  • not great
• Automated Archlinux install and setup using Ansible
  • Git repository

- Maintain the Zigbee network inside of the hackerspace

• SBC: RPi 4 Model B Rev 1.2
• Gateway: Dresden-elektronik Phoscon RaspBee (1) (ITS CURSED)
• took it over from virii
• Network:
  • 2 LED strips
  • 4 Multi sensors

- NOC member

* Fix a bricked CPE210 (Freifunk)

• stuck in boot (accepts TFTP)
• doesn't accept any recovery.bin
• boots on vmlinuz
  • crashes on both wiki vmlinuz and self built openwrt

• Hacked conference phone (Polycom) as a microphone/speaker combo for the Chill. It would most likely have a good microphone for "room" stuff. If the audio cancellation were to be lacking, Mumble's dev 1.4 RNNoise works well.
• Internal SIP network
• Dancing and Singing Animatronics, see @agirisan (natalie)'s 3 robots. (She doesn't do a lot of animatronics, mostly other stuff, documentation and resources are sparse)
• Minitel terminal for the space: interface to different space services, but terminal-based (example)
