LED Skateboard

I went to the 35th Chaos Communication Congress. There we saw a lot of scooters with LED lights underneath. We then discussed that it would be cool if the light would move underneath the vehicle at the speed of the vehicle itself. So this is what I then set out to do.

Scooter with LEDs

• 1 Skateboard
• ESP32 running Micropython
• 2 Lipo Batteries
• Infrared Light Barrier break out board based on TCRT5000
• 1 Switch
• 1 Strip of Neopixels (80 Pcs.)

The Setup of the LED Skate is fairly simple. The infrared light barrier detects rotation of the wheel. These impulses are recognised using the ESP32's GPIO and the color pattern is shifted with the corresponding length.

I used two Lipo batteries. One to power the ESP32 and one to power the Neopixels strip.

The source code can be found on github: https://github.com/besi/LEDSkate.

I decided to put the parts in a tin box to protect it from moisture and dirt. Also I did add a switch that can change the modes as I'm riding the skateboard.
