Following my component break-down here’s a list of everything I think I’ll need and how much it’ll cost.
- Arduino Uno – About £20 depending on where you get it
- Sensor board – £20 or thereabouts
- Brushless motors x4 – £8-10 each
- ESCs x4 – £6-7 each
- RC transmitter/receiver – £15
- 3D-printed frame – no more than £5-10 of plastic
- Battery – £8
- Breadboard/wires – I’ll alow £10 for all of this together
Inevitably the price will change but that comes to just over £90 altogether. That, in my opinion, is incredibly cheap for a working, high-power drone of very good quality (much better than a commercial drone of that price).
For me it’s a lot cheaper because I have a lot of the components already from previous projects. It comes down to £20 for the sensor board (IMU) and a maximum of £10 for the 3D printed plastic, and £10 for wires. That’s a maximum of £40 I’m spending!
Note: I’ve decided upon using an Uno rather than a Micro because I have some already and it will simplify the construction.
