I love controlling stuff with Home Assistant, but having to open the app on my phone each time I want to switch on a light gets annoying really quickly. As I’m also not a big fan of yelling at personal assistants like Alexa or Siri, I wanted to control everything conveniently with physical buttons — and the Elgato Stream Decks are just great for that. So I wrote some software that runs on my Raspberry Pi and connects a Stream Deck with Home Assistant.  Read more

For my ShotBot project (more on that hopefully soon) I needed a holder for a WS2812 module — so I designed one with FreeCAD and 3D-printed it.  Read more

Today we’re going to finish the Arduino Power Strip – or at least bring it to a state where it’s usable for now and can be controlled using Home Assistant. There is also an issue we need to address.  Read more

Time for an update on the Arduino-controlled power strip! In the last post I described how I built the front plate with the outlets and did a bit of wiring—in this post we will do more of that and be able to even test it for the first time.  Read more

I’m building a box to dampen the noise of the projector I bought (more on that in a later post) and to keep it cool I added two fans, one sucking cold air in and one pushing warm air out. To reduce the noise as much as possible I wanted to run the fans as slow as possible, but of course they should still run fast enough to properly cool the projector. So I built a little fan controller with an Arduino that uses temperature to determine the fan speed.  Read more
