This tool helps to find courses and adjusting your own timetable at University of Applied Sciences Brandenburg. Initially it populates the schedule according to your groups timetable. After that you have the option to see what courses are available at all the different time slots if you want to learn new things from other degrees or other semesters of your own. Furthermore you can replace your own courses with other or remove them if you find them uninteresting or you don’t attend them.
Hologram Rail
Arduino ESP8266 frontendPrototype using a tablet
To try out the idea I built a prototype using the edge of a tablet screen. I made a simple JS script to slice up the image and project it onto the edge over a period of time. After that I set an exposure of multiple seconds on the camera and pulled the tablet across the camera.
Circuit
The whole system consists of an Arduino UNO with an SD card module on it. This unit controls the WS2812B LED strip on the vertical stick. It gets the signal to start projecting from the metal bracket that is later mounted on the left end of the rail where the home position is.
