Brains

Raspberry Pi 5

The main computer of the project, runs all main processes like software vision and communicates with other devices downstream.

Plenty documentation support
Fast 2.4GHz processing speed for its size

Pi Hat with Hailo 8L chip (13 TOPS)

A specialized AI chip that is mounted to the Raspberry Pi and helps process video, target recognition and target following to increase frames per second (FPS) and decrease tracking delay.

Boasts a 13 trillion operations per second capacity.
Easy to implement with the Raspberry Pi
Greatly increases software performance

Arduino Uno

Communicates with the Raspberry Pi to control motor movement, activates deterrents and gets readings from limit switches.

Easy to work program
Cost effective
Widely available

HW-095 Motor Controller

Controls power going to the motors, easily connects to the Arduino, and receives a signal that tells the motors which way and how fast to spin.

Cost effective
Can support high current draw (1.5A) which is required for proper motor function

Sensing

OV9732 Camera

Our main device for detecting deer.

Has a 100 degree field of view
Easy to upgrade due to USB type A connection
Capable of 30fps and 1283x720p resolution
Night vision capable with IR CUT filter

Limit Switches

Limit switches will help set the center point for the turret and will define the turning boundaries

Muscle

Fast, precise, and relatively inexpensive stepper motors that move our deterrent.

NEMA 17 Stepper Motor

Deterrence

We use a laser as our deterrent as a proof of concept. We want to make the turrent mount versatile for a wide range of deterrent options.
We chose green due to its enhanced visibility in all conditions (compared to red lasers).

5mW Green Laser

Power

ATX Computer Power Supply

A widely available computer power supply that is perfect for powering all necessary components.

Has many different available voltages (3.3V, 5V, 12V)
High current availability
Free by donation from the electronics prep room

Printed Circuit Board

The main function of our circuit is to merge all power from devices into one cable that will go into the wall outlet.

Extra USB A ports for devices and I/O pins
Connected to receive power from computer PSU
Built for high current load
