Configure Raspberry Pi and Sense HAT for logging

Smart buildings are a really hot item right now, but how smart is your home? And how much do you know about what is going on in your home, when you are not there? What is a useful data-set to create? What data can you create? Luckily I got my hands on some Raspberry Pis with a Sense HAT Kit. Now I could try to answer these questions myself! I really wanted to figure out how the Raspberry Sense Hat kit worked. To my big surprise, it was rather easy to create a nice script that writes the Raspberry Pi SenseHat sensor data to a log file. This enabled me to analyze my data later-on by importing the log file into a spreadsheet program like Libre Office (or something similar). The spreadsheet enabled me to create nice graphs. As I’m always curious I tried this in a friendly environment at home, and in the harsh environment of my wife’s atelier where the environmental conditions are constantly changing caused by the warmth of the winter and heat produced by the glass kilns.

How to install PaPiRus on your Raspberry

PaPiRus is a lovely little E-Ink screen for your Raspberry Pi project. In this how-to, I’ll try to explain what you need to do to make it work on your Raspberry Pi. I started from my Ubuntu Studio 19.10, but virtual any OS will do the first steps namely installing Raspbian.

Batch convert TIFF to JPG

After years of following courses and workshops I ended up with piles of books and papers, so reducing valuable storage space I found myself scanning them all. The result was a large collection of TIFF files. And for some reason, I needed a JPG or JPEG version of several of them. This is how I did that in Ubuntu.

How to find the Key of a song

Getting the key to a song might seem difficult… But really, it is NOT! You can of course use some (expensive) software tool, but there is no need for as you can easily do it yourself.

Gverb presets

Gverb is a great reverb tool for adding reverberation to your audio. Just like many other people, I was looking for some great Gverb settings. I’ve found several and listed them below for you.
