I first learned about the “WAF” at work during a lunch discussion between engineers, on self-made domotica projects. Apparently the major reason such a project fails or succeeds is the “Wife Acceptance Factor”. According to some, the same WAF is the most critical point in every decision when buying a new television, radio or any electronic device with a complex remote control.

One of the example applications in my book “Getting started with Java on the Raspberry Pi” combines a JavaFX application with Mosquitto on the Raspberry Pi to control a LED strip with an Arduino. All wireless and independent of each other as the Mosquitto-queue is dealing with exchange commands between all applications.

A story of bits, bytes, signed and unsigned

Some time ago there was a question on the Pi4J-forum caused by some confusion about a numeric value handled as a byte which was logged as a negative number -86 instead of the expected value 170. So this is my attempt to try to solve this mystery… ;-)

My very first open source JavaFX library is now available in the Maven repository! A small step for mankind, one giant leap for myself ;-)

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!
