Introduction: Black Mirror

About The Project

It’s an entertaining, relaxing speaker which can be in balance with a minimalistic design of a room. It provides a unique experience of manipulating music accompanied by an exquisite visualization of movement in a ferrofluid surface. We call it the Black Mirror.

Step 1: List of Parts Required

Arduino - 1

Led Lights - 1

Ultrasonic Sensors - 2

Servo Motor -2

Magnets - 8

Jumper Wires

Iron Powder

Mineral Oil

Step 2: How Does It Work?

Step 1 - Making the ferrofluid

To make the magnetic ferrofluid the iron powder with the mineral oil to get the right consistency.

Step 3: Step 2 - Building the Arduino Circuit

Step 4: Step 3 - the Code

We developed our code to control and test our circuit, to make sure it worked as per our requirement.

Step 5: Step 4 - the Structure

We designed and laser cut the casing for the speaker case.

Step 6: Step 4 - the Structure - Placing the Magnet

We created supporting structure to place the magnets on the servos. Also, laser cut an inner shelf to put the magnets on below the iron liquid.

Step 7: Step 5 - Adding Music Volume Control Feature to the Ultrasonic

We used the Max console software to code the volume control feature of music with ultrasonic sensor.
