In one of our previous articles, we built a DIY air quality monitor which was based on measuring the amount of Hydrocarbon concentration in the air using the BME680 VOC Whisker. While things work quite well using that method, there are several other parameters and air constituents which also have the same devastating effect and may be present in the air, […]

SjoelSim! Is a mixed-reality version of the popular and historic Dutch shuffleboard game “Sjoelen”. The circuit makes use of two HC-SR04 ultrasonic distance sensors to measure the X and Z velocity of a playing disc. In combination with a program built in the Unity Engine, it makes for a pretty good alternative to the real
A birdhouse controller for a bird based game, why? I saw this birdhouse in the store and felt instantly inspired! Going from something big and grand with a shortage of time for the school’s deadline to something small and cute. It inspired an entire game around it! It was an interesting project, I learned how
