About this 3D model

Summary What it is? It is a timer for your fpv drones and whoops. How does it work? It uses the video transmission signal to estimate the position of the drone, so no new hardware needed on the drones. You calibrate the signal in a certain "gate" and then track your lap times with it. Make one Print the case and order the parts. You have to superglue the switch slider parts. The two teardrop-shaped holes need to be filled with some translucent material. They difuse the ESP32 T8 leds, I used a 3d pen and translucent PLA as you can see in one of the photos.

I adapted the firmware to run on the ESP32. In the future it could work standalone, using BT, Wifi and the SD capabilities of the microcontroller.
