## Problem
It is a hassle to collect and combine the precise amount of each seasoning required in a recipe, leading many to just eyeball amounts. Sometimes, this can create new and exciting forms of existing recipes. However, laziness in the kitchen can also lead to inaccurate tasting recipes and may even ruin the dish depending on which seasonings were misused.

## Solution Overview
Our solution is to create an automated system for dispensing precise amounts of each dry seasoning required in any particular recipe. The user can simply input the amount of each seasoning that their recipe requires using our UI, and the product will make use of augers to precisely dispense the exact amount specified. The product will be able to hold salt and pepper, which can easily refilled and replaced by the user at will.

## Uniqueness
Currently, there are a couple of products on the market that allow the user to dispense select amounts of spices; however, most of these products do not automate this process. The user must twist dials to dispense fractions of tablespoons at a time. For a large recipe, this can prove to be very tedious. Our low-cost solution will allow for varying amounts of each spice to be dispensed at a time, saving the user from having to manually twist dials tens of times.
The recently released TasteTro is similar to our design; however, it does not allow the user to refill their spices. Once you run out of a certain spice, you have to buy one of their pre-filled cartridges. Also, the Tastro costs $270, which makes it unaffordable for a large number of potential customers. Our design will allow the user to refill our reusable cartridges, which allows for a more economical product.

## Solution Components

### Power
AC/DC converter for wall power

Custom designed Buck Converter for stepping down voltage levels for motors
### Control Unit
Microcontroller handles interface with LCD Display, physical push buttons, seasoning level sensor, and motors

Level Sensor to determine if seasonings need to be replaced or refilled

LCD Display and push buttons to allow the user to configure the amounts of each seasonings to dispense.
### Dispenser unit
Augers + Motors for dispensing powder seasonings

Custom storage bottles for holding seasonings

## Criterion For Success
The ASD will allow the user to choose exactly how much of salt and pepper to dispense, and will then dispense those amounts precisely after the program is run.

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.
