Summary

TLDRThis tutorial guides you through the innovative process of controlling a drone with your mind using the Neurosky MindWave Mobile. It covers the essentials, from disassembling a drone controller and setting up potentiometers to building a circuit with an Arduino MKR1000 and creating a Processing sketch for mind-controlled flight. The video demonstrates how to connect the mindwave sensor, calibrate attention levels, and safely operate the drone with a focus on concentration, ensuring a hands-free, thought-driven flying experience.

Takeaways

  • 🛠️ The project requires a drone, its controller, a soldering station, a multimeter, Neurosky MindWave Mobile, Arduino MKR1000, and various electronic components.
  • 🔍 Disassembling the drone controller is the first step, being careful not to damage the internal circuit board.
  • 🔧 Desoldering is necessary to remove the joysticks from the controller, revealing the potentiometers within.
  • ⚡ The multimeter is used to measure and match the resistance of the potentiometers, typically 10k ohms.
  • 🔌 Soldering is performed to attach resistors and wires to the potentiometers to facilitate PWM to analog voltage conversion.
  • 🔄 A digital to analog converter circuit is constructed using capacitors and resistors to filter the PWM output from the Arduino.
  • 🤖 The Arduino MKR1000 is the central component for building the main circuit, requiring careful wiring and connection to the controller.
  • 🔌 Proper wiring of the Arduino to the controller is crucial to avoid short circuits, with attention to VCC and GND connections.
  • 📱 The Arduino sketch is uploaded to control the drone's throttle, yaw, pitch, and roll variables.
  • 🧠 The Neurosky MindWave Mobile is used as a brainwave sensor to control the drone, requiring Bluetooth pairing with a computer.
  • 💡 The Processing code is essential for translating brainwave data into drone control signals, with a focus on the 'attention' value.
  • 🛑 A kill-switch feature is included in the Processing sketch to ensure safety by setting the throttle to zero in case of an emergency.

Q & A

  • What is the main objective of the video tutorial?

    -The main objective of the video tutorial is to teach viewers how to lift-off a drone using their mind.

  • What are the required materials for this project?

    -The required materials include a drone and its controller, a soldering station and accessories, a multimeter, the Neurosky MindWave Mobile, a micro USB cable, the Arduino MKR1000, a breadboard, 4 100uF capacitors, 4 220Ω resistors, 12 jumper wires, and 6 crocodile clip wires.

  • Can any drone be used for this project?

    -The script suggests that this project should work with any drone, and even a cheap drone costing €10 from an outlet store can be used.

  • What is the first step in modifying the drone's controller?

    -The first step is to open the case of the controller using any necessary force without damaging the circuit board inside.

  • Why is a multimeter used in this project?

    -A multimeter is used to measure the resistance of the potentiometers in the joystick to ensure they have the correct resistance of 10k ohms.

  • How many resistors are needed to replace the potentiometers in the joysticks?

    -Four 10k ohm resistors are needed, one for each outer end of the two potentiometers in the joysticks.

  • What is the purpose of building a digital to analogue converter (DAC) with a low pass filter?

    -The purpose is to convert the PWM output from the Arduino to an analogue voltage, which is necessary for controlling the drone's controller.

  • How does the Arduino circuit provide power to the controller?

    -The Arduino circuit provides power to the controller by connecting the red wire to the VCC for a 3.3-volt output and the ground (GND) with a black wire.

  • What is the role of the Neurosky MindWave Mobile in controlling the drone?

    -The Neurosky MindWave Mobile is used to detect the user's brainwave activity, specifically the attention level, which is then sent to the Arduino to control the throttle of the drone.

  • What is the minimum attention level required to lift-off the drone according to the Processing sketch?

    -A minimum attention level of 40 is needed to initiate the lift-off of the drone.

  • How does the 'kill-switch' function in the Processing sketch work?

    -The 'kill-switch' function terminates the program and sets the throttle to 0 in case something goes wrong, ensuring safety during experimentation. It can be activated by pressing the 'K' key.
