Some links to pages i created or maintain. Some of these are not generally linked (yet) within the rest of the wiki hierarchy

Resources on the wiki

  • 78xx power supply How to design and build a 78xx-based power supply
  • Justa_copter_1 Working on a small quad-copter *COMPLETED*
  • Justa_copter_2 A second 330-class quadcopter after the first one.. err.. crashed
  • Justa_mini_fpv A 250-class 'miniracer' FPV quadcopter based on a ZMR250 frame
  • Justa_versawing The 'FliteTest' VersaWing design; adapted for FPV flying
  • Justa_learning_to_fly Now it's time to learn to fly this thing.
  • Turnigy_9xr-pro Information about configuring, using, modifying the Turnigy 9xr-pro; focus on Linux-usability.
  • quadcopter_workshop Workshop(s) and talk(s) concerning multirotor aircraft. Designing, building, flying them
  • platformio_workshop Workshop regarding the move from Arduino IDE to PlatformIO
  • esp_workshop Workshop regarding the ESP8266/ESP32 ecosystem ,
  • crypto-mail-safe Suggestion for implementation of crypted mail-store for secure storage of sensitive documents
  • mail_to_hobbyking My mail to hobbyking about what they do and how they do it and how to do it better.
  • crash_counter And here is where we keep track of all the things we broke while flying.
  • space_related_documents A page with a list of resources, documents, templates that are space-related.
  • open_source_brewing_resources A page with lists of resources for (home)brewers using open source/standards
  • led-n-sound-toy An idea i've been working on
  • JustaDome Standardized miniature-sized 'festival-dome' from trashed bed-slats
  • Cornelius-Kegs_Howto Explanation on what they are and how to use them; as broad as possible.
  • Justa_Beer_Brewing_Howto An attempt at giving a bird-flight overview into what goes into brewing beer, written down from my totally biased, unscientific, vantage-point.
  • DDS238-1-esp8266 A small description of how I hooked a DIANQI DDS238-1 to an ESP8266 via the S0 connection for rudimentary MQTT-reporting.
  • APC7921 An overview of how an APC 7921 PDU is wired internally
  • APC7921-esp A project to re-do the controller-hardware of the APC7921's using an ESP(32). Most likely the ESPHome firmware can be made to provide all functionality.
  • chair_repair This is how to repair a chair at techinc
  • space-labeling-draft A draft , WIP document about how to implement some kind of labelling/inventory-system at Techinc
  • Work-adventure A collection of pages regarding work-adventure @ techinc

Personal interests

Just a postit-note for myself with info on mediawikidb select user.user_id,user.user_name,user_email,user.user_email_authenticated from user where user_id not in (select distinct ipb_user from ipblocks); or select user.user_id,user.user_name,user_email,user.user_email_authenticated from user left join ipblocks on user.user_id = ipblocks.ipb_user where ipblocks.ipb_user IS NULL;

Personal short-term goals

Get Interspatial Pale ale working Get ACTA-doorbell project installed with help of Brainsmoke (aka: aid him in all i can) Get INFO-board (screenly) working for ACTA/UR in the hallway to get rid of ridiculous HP issues membership_process_wip
