white and black helmet on motorcycle
How to Turn a Motorcycle Helmet into a Makeup Artist, Bald Head Massager, and Hair Washer with a Hydro System

In an age of smart homes and wearable tech, your motorcycle helmet doesn’t have to sit idle in the garage. With a bit of ingenuity, a microcontroller, and 3D-printed components, it can evolve into a personal grooming robot — capable of applying makeup, massaging bald scalps, and even washing hair with a built-in hydro system.

This guide walks you through the technical steps to build this multifunctional smart helmet, from circuit design to mechanical assemblies.

🧰 Components You’ll Need

CategoryComponents
BrainArduino Nano (or ESP32 if you need Wi-Fi/BLE)
Power5V USB Power Bank
MotionMicro Servo Motors (SG90 x4–6), Vibration Motors
HydroPeristaltic Pump, Water Reservoir, Nozzles, Drain Tube
SensorsIR Proximity Sensor, Capacitive Touch, Camera (Optional)
Extras3D-printed parts (.STL), Flexible tubing, PCB or Perfboard

🔩 System Overview

1. Makeup Artist Module

  • A servo arm assembly inside the helmet holds mini sponges or brushes.
  • Servo motors rotate arms to apply makeup (foundation, blush).
  • Makeup can be dispensed using micro pumps attached to refillable pods.

2. Bald Head Massager

  • Vibration motors embedded in soft pads touch the scalp gently.
  • Timed or touch-triggered using capacitive sensors.
  • You can create wave patterns (temples to crown) using PWM signal modulation.

3. Hair Washer Hydro System

  • A peristaltic pump draws water from a rear-mounted tank.
  • Nozzles 3D printed and arranged in a ring shape around the inner dome spray water evenly.
  • A soap valve (servo controlled) dispenses shampoo.
  • Water drains via a back-mounted flexible tube.

⚡ Wiring and Circuit Design

Power Flow:

  • 5V USB bank → Arduino Nano + PCA9685 (PWM driver) + Motors
  • Use a buck converter if any module requires 3.3V

Wiring Overview:

  • Nano controls:
    • Servo pins: D3–D9
    • Vibration motors: D10 (via NPN transistor)
    • Pump + Valve: D11, D12
  • PCA9685 can be added if more PWM outputs are needed.

Safety Tip: Add a reset switch outside the helmet for emergency shutdown.

🧠 Programming Logic

You can program the Nano with Arduino IDE.

Example Functions:

void applyMakeup() {
  servo1.write(90); // Extend arm
  delay(2000);
  servo1.write(0);  // Retract
}

void massageMode() {
  digitalWrite(vibrationPin, HIGH);
  delay(5000);
  digitalWrite(vibrationPin, LOW);
}

void washHair() {
  digitalWrite(pumpPin, HIGH);
  delay(4000);
  digitalWrite(pumpPin, LOW);
}

Control sequences can be triggered by buttons, or even BLE if you use an ESP32.

🧱 3D Printing & Helmet Integration

STL Files to Design:

  • Servo mounting bracket for helmet interior
  • Nozzle ring with 6 micro jet outputs
  • Massager pad holder with vibration dampening
  • Modular back tank unit (water + electronics)

Use Fusion 360, Tinkercad, or FreeCAD to model these components.

Print using PLA or TPU for flexibility.

🧪 Testing & Calibration

  • Makeup: Calibrate servo angle + pressure for gentle application.
  • Massage: Tune motor intensity and duration for comfort.
  • Hydro system: Test water flow, sealing, and nozzle direction.

Add waterproofing inside helmet: use silicone gaskets around pump mounts and electronics bay.

Conclusion

This project isn’t just a quirky gadget—it’s a bold leap into personalized wearable robotics. Turning your motorcycle helmet into a smart grooming assistant blends innovation, comfort, and cyberpunk aesthetics.

Whether you’re prepping for a ride or just want a hands-free spa moment, this helmet’s got your head covered—literally.
