This project was designed for my little dog called Luna who loves chasing laser pointers.
So, I created this toy which plays with her while I am busy building something else. For her safety, this laser is power adjustable and moves with different speeds and effects. Also, it allows me to coontroller the laser pointer with an external controller (Wii nunchuk).
This project was 3D/hardware/firmware designed 100% by me and enjoyed by her. The firmware implementation was implemented using C++ and FreeRTOS on the ESP32 microcontroller.
This hardware has rechargeable batteries and a box to accommodate the hardware and laser motors.
How it looks like:
