Introduction: Glitterminator

Annoyed by loud people in the silence part of the train? Or in the cinema? Don't they listen when you tell them to shut up? We've got the solution: the Glitterminator! The Glitterminator is embedded into the back of the chairs and measures the amount of sound in the room. When the sound is too hard a red light will activate. Still too loud? The Glitterminator gives you a bright new fancy look by literally shooting you in the face with pink, shiny glitters.

Step 1: Requirements

Materials

  • Arduino
  • Breadboard
  • Microphone Sensor
  • 2 rotary motors (from a nerf gun)
  • Servo
  • about 20 jumper wires
  • Additional wiring
  • Small canister
  • Small wooden sticks (popsicle sticks)
  • Wooden planks
  • 4 screws
  • Thread
  • foil
  • tape
  • Glitter
  • Headrest (optional)
  • Spray paint (optional)

Tools

  • Saw
  • Drill

Step 2: Rotary Motors

Disassemble your nerf gun and get the 2 rotary motors and attached wires inside. Use a saw to cut the plastic so you have two seperate motors.

Place the two motors on your board. Keep enough space between the 2 motors so your canister fits in between.

Use the small wooden sticks to keep the motors upright and drill them and the motors into your board.

Place 2 sticks behind the motors sticking up so the canister stays still.

Step 3: Canister

Close off one end of the canister with some foil and tape. Attach your thread with glue to the foil and to the back of the board. Make sure the thread is long enough to make the canister get fired by the rotary motors and to be tightened shortly after.

Place the canister between the 2 sticks pointing up, just behind the motors.

Step 4: Servo

Picture of Servo

Place a wooden stick on your servo and stick them together using tape.

Place the servo behind your right motor so the end of the stick will push the canister. Either glue or tape the servo to your board, make sure it stays still when it's rotating.

Step 5: Warning Light

Connect 2 wires to each end of your LED and connect these to your breadboard. Connect your plus(the wire on the long side of the LED) to digital pin 7 and put the negative wire to a negative pin on your breadboard.

Glue your LED to the board, somewhere at the front.

That's it! Now load up your canister with glitter and place it in front of someone. To make it look more fancy, use the spray paint to color your headset.

Step 6: The Microphone

Picture of The Microphone

Place your microphone sensor on your breadboard with G going to ground, plus to plus and A0 to A0 on your Arduino. Keep your Arduino some distance from your motors because they might make some noise on their own.
