Yesterday I started with something I had in my mind for a very long time:
to build my own DIY drone based on a Kinetis 🙂
I did some research over the last months and learned a lot about how to build drones and quadrocopters. Yes, you get excellent ones for the money, but hey: it is all about learning new things ;-). I was on the search for a good quadrocopter frame, so I visited a store in Lucerne, and finally found one which I wanted to use: the Graupner Alpha 250Q.
It comes all the frame parts, 4 brushless DC motors and ESC’s, and has a compartment to store battery/electronics. The Alpha 250Q is intended for first-view race events and as FPV (First Person View) copter, but this is not what I have originally in mind. I want to develop and use my board, firmware and remote control. And this kit is ideal for me as it fits my needs.
The kit comes with all the frame parts, bolts, 4 motors and ESC (Electronic Speed Controllers). I added a battery (14.8V, LiIon, 4S, 26.6Wh), extra rotor blades and an adapter cable for my charging station:
The frame is made of carbon fibre which holds the four brushless DC motors:
The motor wiring and the four ESC’s are placed in a special compartment on the underside of the drone. Here it still looks a bit messy:
But everything gets covered under a bottom plate:
Here a picture with battery in the compartment and a possible place for the FRDM board:
💡 Note that the SD card connector shown in the picture is not on the board by default.
As IMU I plan to use the FRDM-STBC-AGM01 9-Axis Inertial Measurement Board:
Initially, I plan to write my simple firmware. But I consider as well to port the OpenPilot framework to Kinetis. As most of the time: using Open Source software and tools :-).
Happy Droning 🙂
