  This tutorial opens the series of articles about "Project JiJi" and describes how to add autofocus to the 16 mm Telephoto Lens mounted on the Raspberry Pi HQ Camera. In the past months, I've been working on a project to add autofocus to the lens and this is the result:

  Adding some background to this: The Raspberry Pi Foundation offers different Raspberry Pi Camera modules since 2013. The first module (5-megapixel) was produced in 2013, and an 8-megapixel module upgrade (...

  Winter is coming and the air-quality inside a closed room could be an index used to estimate the amount of aerosols in it, and hence the risk of Covid-19 infection. In other words, a system of CO2 traffic lights could help to spot potential corona-aerosols!

  Where there are many people in a room, there is a lot of exhalation (approx. eight liters of air per minute per nose). This air contains CO2 (carbon dioxide). Long before Covid-19, in Germany, the German Environment Agenc...

  Two weeks ago, I published a tutorial that explains how to connect an M5Stack running MicroPython to the Google Cloud Platform using the IoT Core, and I did mention that upcoming tutorials will examine the following topics:

  • Collecting and synchronizing external data (weather from OpenWeatherMap) and other sensors -window/door status, sneezing detector-.
  • Saving the data to a NoSQL database
  • Displaying the obtained data on Google Data Studio (chec...

  The last days, I was looking for an online project management tool with bug tracking system. The best platform that I know is Jira from Atlassian. Jira offers a bug tracking and agile project management, however, it costs between $8.33 and $10 (annual/monthly payment) for the standard version with under 10 accounts. We use Jira in Finealyze and I am very happy with it, but I was looking for a free alternative for myself. Then, I found OpenProject, which describes itself as "the leading open source project management software".

  OpenProject is offered in three different ways: Community, Cloud an...
