# Problem
FPV Racing drones are usually very large and fast and thus require a large space. The Center for Autonomy Labs has a flying arena for lightweight drones such as the Crazyflie. However, the Crazyflie do not have a first person view.

# Solution
We propose to develop a small, lightweight FPV system for the Crazyflie in order to facilitate lightweight, small-space drone racing.

# Solution Components
## Power system
The system will draw power from the Crazyflie and use regulators to power each of the subsystems.

## Camera
A lightweight camera will be used to capture video from the drone.

## Transmitter/Receiver
A video transmitter on the drone will stream the video from the camera to a receiver connected to the headset.

## Video Processor
Microprocessors on the drone and at the receiving end will convert the camera data for transmitting and the received data back to video for the headset.

## IF LED Array
In order to track the location of the drone for the purpose of racing analytics, an infrared LED array will be attached to the drone to display a programmable pattern. This would allow the simultaneous tracking and differentiation of multiple drones in the future. This will be tracked using the labs Vicon motion tracking system.

# Criterion for Success
1 – The Vicon motion system should successfully track the drone using the IF LED array.

2 - The headset should receive a video stream of at least 30Hz.

3 – The Crazyflie should be able to maintain flight for 3 mins with the system running.

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.
