# SELF SOLVING/SCRAMBLING RUBIK’S CUBE FOR LEARNING AND TRAINING

# PROBLEM
Rubik’s cubes are fun to learn and solve, but scrambling them can be a pain. You have to turn all the sides in random directions, but you may have subtle biases in how you turn the cube. This results in a non-random scramble and worse practice for solving.

For users that do not know how to solve the cube, it can often be difficult for them to learn. There are many algorithms that must be memorized and they can be intimidating for beginners trying to learn.

# SOLUTION
A cube with integrated motors, for turning all six sides, that can scramble itself with a random (or pseudorandom) scramble. This will help increase skill level by giving users patterns that they were not previously giving to themselves due to subtle biases in their scrambling.

The cube will also be able to use the same motors and controllers to return itself to a solved state. This opens the door for teaching users the correct algorithms that they must use in order to solve the cube.

# SOLUTION COMPONENTS
## POWER AND CHASIS
- Small battery for power
- 3D printed Rubik’s Cube:
- The cube will need to be custom designed to hold the electronic components and motors within it. It will likely be larger than the classic Rubik’s cube as a result.
## CONTROL SYSTEM
- Micro Controller (STM32)
- Reads sensors and controls motors. Runs algorithm to scramble and solve cube
## TURNING SYSTEM
- Motors
- 6 motors are needed to rotate the sides of the cube.
- Hall effect sensor and Magnets
- The hall effect sensor will use the magnets to coordinate stopping points with the motors. This will make sure that each side gets turned the correct amount.


# CRITERION FOR SUCCESS
- Self scrambling capabilities that will put the cube in a randomized state.
- Self solving capabilities that will return the cube to a solved state regardless of previous state

Master Bus Processor

Featured Project

General Description

We will design a Master Bus Processor (MBP) for music production in home studios. The MBP will use a hybrid analog/digital approach to provide both the desirable non-linearities of analog processing and the flexibility of digital control. Our design will be less costly than other audio bus processors so that it is more accessible to our target market of home studio owners. The MBP will be unique in its low cost as well as in its incorporation of a digital hardware control system. This allows for more flexibility and more intuitive controls when compared to other products on the market.

Design Proposal

Our design would contain a core functionality with scalability in added functionality. It would be designed to fit in a 2U rack mount enclosure with distinct boards for digital and analog circuits to allow for easier unit testings and account for digital/analog interference.

The audio processing signal chain would be composed of analog processing 'blocks’--like steps in the signal chain.

The basic analog blocks we would integrate are:

Compressor/limiter modes

EQ with shelf/bell modes

Saturation with symmetrical/asymmetrical modes

Each block’s multiple modes would be controlled by a digital circuit to allow for intuitive mode selection.

The digital circuit will be responsible for:

Mode selection

Analog block sequence

DSP feedback and monitoring of each analog block (REACH GOAL)

The digital circuit will entail a series of buttons to allow the user to easily select which analog block to control and another button to allow the user to scroll between different modes and presets. Another button will allow the user to control sequence of the analog blocks. An LCD display will be used to give the user feedback of the current state of the system when scrolling and selecting particular modes.

Reach Goals

added DSP functionality such as monitoring of the analog functions

Replace Arduino boards for DSP with custom digital control boards using ATmega328 microcontrollers (same as arduino board)

Rack mounted enclosure/marketable design

System Verification

We will qualify the success of the project by how closely its processing performance matches the design intent. Since audio 'quality’ can be highly subjective, we will rely on objective metrics such as Gain Reduction (GR [dB]), Total Harmonic Distortion (THD [%]), and Noise [V] to qualify the analog processing blocks. The digital controls will be qualified by their ability to actuate the correct analog blocks consistently without causing disruptions to the signal chain or interference. Additionally, the hardware user interface will be qualified by ease of use and intuitiveness.
