# Electronic Page Turner

# Problem:

Page turning is required when reading a book. This is typically done with one's hands, which can be an inconvenience for those wishing to multitask while reading, such as playing an instrument or using a cookbook while cooking. This is a challenge for both avid readers and people with disabilities. There are hands-free page turners that exist, but most are expensive and typically designed for electronic reading on tablets.

# Solution:
The solution for this problem will use three different subsystems: actuation, sensors, and power. Our solution is unique because it is a hands free page turner for a physical book that can turn an unlimited number of pages.

# Solution Components:

## Actuation Subsystem:
- Stand with a Lever/Arm
- This would be controlled by servo motors to turn the pages
- Two would be needed to flip pages forward and backwards
- Adjustable levers to accommodate different sized books

## Power Subsystem:
- Uses batteries to power required subsystems and allow for portability

## Sensor Subsystem:
- Button (easy) Using a foot pedal to turn the page forward and backwards

_If we are able to meet the minimum requirements for success, we will try to implement the following bullet points:_

- Audio (medium) Using a microphone to turn pages forward when “Next” is said and backwards when “Back” is said
- Vision (hard)
Computer vision would be used alongside a camera to flip the page. It would be placed on the bottom left and right corners near the book and use some sort of facial cue in order to turn the page.

_If we are able to meet the minimum requirements for success, we will try to implement the following subsystem:_

## Processing Subsystem:
- A screen that displays the total pages flipped and how many pages were flipped in one sitting. This can help bookmark where you left off.
- Include a timer to keep track of how much time you have read i.e. if someone wants to read for 30 mins the device can make a sound letting the user know the time is up.


## Criterion for Success:
- A stand for the book with levers for turning pages in the book
- Has to be able to flip one page at a time, forward and backward
- Should be able to go through all the pages in a book
- Must be able to flip the pages using a foot pedal

# Problem

Piano tuning is a time-consuming and expensive process. An average piano tuning will cost in the $100 - $200 range and a piano will have to be retuned multiple times to maintain the correct pitch. Due to the strength required to alter the piano pegs it is also something that is difficult for the less physically able to accomplish.

# Solution

We hope to bring piano tuning to the masses by creating an easy to use product which will be able to automatically tune a piano by giving the key as input alongside playing the key to get the pitch differential and automatically turning the piano pegs until they reach the correct note.

# Solution Components

## Subsystem 1 - Motor Assembly

A standard tuning pin requires 8-14 nm of torque to successfully tune. We will thus need to create a motor assembly that is able to produce enough torque to rotate standard tuning pins.

## Subsystem 2 - Frequency Detector/Tuner

The device will use a microphone to gather audio measurements. Then a microprocessor processes the audio data to detect the pitch and determine the difference from the desired frequency. This can then generate instructions for the motor; direction to turn pegs and amount to turn it by.

## Subsystem 3 - User Interface/Display Panel

A small but intuitive display and button configuration can be used for this device. It will be required for the user to set the key being played using buttons on the device and reading the output of the display. As the device will tune by itself after hearing the tone, all that is required to display is the current key and octave. A couple of buttons will suffice to be able to cycle up and down keys and octaves.

## Subsystem 4 - Replaceable Battery/Power Supply

Every commercial product should use standard replaceable batteries, or provide a way for easy charging. As we want to develop a handheld device, so that the device doesn’t have to drag power wires into the piano, we will need a rechargeable battery pack.

# Criterion For Success

The aim of the Automatic Piano Tuner is to allow the user to automatically tune piano strings based on a key input alongside playing a note. We have several goals to help us meet this aim:

- Measure pitch accurately, test against known good pitches

- Motor generates enough torque to turn the pegs on a piano

- Tuner turns correctly depending on pitch

- Easy tuning of a piano by a single untrained person
