And another summer project got finished… ;-)
My sons drum corps teacher triggered me to build an Arduino Midi controller so he could practice his rhythm skills.

As a summer project requires, this project required a summer to get completed ;-)

I still need to think about a big (double) door and how to make that one with or without glass. But the booth itself is ready and the drum moved for a first test and audio measurement.

To work out my box-in-a-box I needed two types of materials: something “fluffy” for the walls, and something “strong” to carry the floor.

What do you get if you combine a drum-playing son and a father who doesn’t like to spend thousands of euros? A DIY drum booth! ;-)

Great move of Microsoft!

They provide an all-in-one installer for Java dependencies and Visual Studio Code. Take a look at https://devblogs.microsoft.com/visualstudio/announcing-visual-studio-code-java-installer/

Some time ago I ordered a “Breadboard Pi Bridge - Pi Ports to Breadboard in Numerical Order” and reworked my Pi test setup from the previous blogs. And it looks really good!

What is Pi4J

See https://www.pi4j.com/1.2/index.html

This project is intended to provide a friendly object-oriented I/O API and implementation libraries for Java Programmers to access the full I/O capabilities of the Raspberry Pi platform. This project abstracts the low-level native integration and interrupt monitoring to enable Java programmers to focus on implementing their application business logic.

As I was learning Spring Boot myself, I thought the easiest way to learn was trying to build an example and write about it. So here we go… :-)

While trying out what Pi4J can do, I found it could easily be extended with a JavaFX application to provide info about the headers on a Pi board. This could later be extended to a remote/local (touch) User Interface using the REST interface from this post.

As my daily work mainly is Java and back-end stuff on “real servers”, I set myself for 2019 as a personal goal to experiment with Java 11 on a Raspberry PI.
