The aim of the project is to measure the energy consumption of the hoverboard during different driving situations. For this reason, Niklas Roy decided to develop a power meter similar to the car’s on-board computer.
Roy’s handheld device is controlled by an Arduino Nano and utilizes a Hall effect current sensor. The measurements are shown as numbers and as oscillograms on a 1.8” TFT screen, which can also be logged to the display’s built-in SD card. An RTC module provides timestamp information for these readings, which can be produced using Processing and overlaid on video.
