For this Drone you will have to solder Smd components. you will also
have to tune some values.
Step 1: Things You Need
Buck Converter:Mini 360
Motor:(I used some old from an old Drone)
Propeller:(I used some old from an old Drone)
Step 2: Solder the Circuit
Solder the Circuit following the schematic. Adjust the smal Buck Converter to 3.3v. Conect 3.3v to the 5v input.
Step 3: Build the Bodey
Use some Tape to make the Arms of your Drone. They have to be about 1/2 of the diameter of the propeller long.
Now Tape the motors to your Arms. Cover the main pcb in Tape so you can now conect the Arms to the Bodey via Tape.
Step 4: Upload the Code
Now upload the Code to your Atmega via a breakoutboard. I have used a micro usb port to keep it small so you have to build an Adapter. D- = RX, D+ = TX, GND =GND, VBUS =VBUS, DTR =Metal Wall. You have to tune your PID values for your Drone(how).
