Marbles counting for all: get the 1.2.0 test version at phyphox.org/download/ (in the accustomed beta quality). Highlights: luminance or hue/saturation/value measurements, brightness or color stopwatches, brightness spectrum (soon on Android), several new UI elements (soon on Android) #ITeachPhysics

That's gonna be fun…

Something (relaxing) for the weekend… 〰️ #ITeachPhysics #MINTEdu #PhysikEdu
