Making a custom electronic speed controller for my drone’s motors

  • ESC V5 - Newest revision to the ESC. Largely designed to use the available MOSFET drivers.
  • ESC V4 - Another major revision to the BLDC ESC, mainly changing to the modern ATtiny family of microcontrollers.
  • ESC V3 - A revision of ESV V2 with the voltage regulator removed
  • ESC V2 - My first actual attempt at building an ESC. A shrunk down revision of the first.
  • ESC V1 - My first attempt to make a sensor-less ESC for my drone

Making a a custom flight controller for my drone to work with my custom ESCs and potentially other electronics.

  • Flight Controller V2 - My more powerful STM32 based version of a flight controller. Currently on hold.
  • Flight Controller V1 - My first flight controller design. Based on an ATmega328P so I could adapt many open-source drone projects to it if needed.
