I have a room that - in winter - needs some heating. Instead of connecting it to my central heating system, I decided to use my mobile AC which can also heat.

To better understand the efficiency and behaviour of my old gas heater, I created a simple monitor for flow and return temperatures.

Nach der Analyse des Gasbedarfs der Monate Oktober-Dezember erweitere ich die Betrachtung um die Monate Januar und Februar 2023.

After accidentally ruining the glas bed of my Artillery Genius Pro I decided to install a spring steel sheet with PEI surface.

Seit Oktober 2022 habe ich die oberste Geschossdecke meines Walmdach-Bungalows gedämmt. Hier erfahrt ihr, was es gebracht hat - und was es alles so auszuwerten gibt.

In this simple project I want to build a box that allows my children to enter the house with a fingerprint sensor. At the same time this project doubles as a prototype for video doorbell with fingerprint sensor that I might want to build later.

Prerequisites

In my case we are owning a Nuki door lock already: So basically a small box on the inside of my front door that turns the door key when told so via Bluetooth. In my case I am also using the so-called “Nuki Bridge”: That again is a small box in the hallway that can be told via API to tell the small box on the front door via Bluetooth to turn the key. What a wonderful new world!
