Shot detector

Overview

A modern remake of my senior project from college.

"Smoke & Hope" was my college project and was a competition shooting timer. It originally used:

• FPGA development board
  • I designed a soft-core processor and a custom DSP module in VHDL
  • Wrote the timing and graphics in C++
• Custom vibration sensor (for detecting the gun shot)
• Resistive touch screen

This project (also named after a classic competition shooting course) is a "re-take". I'm looking to:

• Modernize
• Miniaturize
• Make portable

Features

• Built on the Raspberry Pi Pico
• 1.14 inch LCD display
• Custom PCB for the vibration sensor circuit
• Battery powered
• 3D printed case

Resources

• Raspberry Pi Pico
• 1.14 inch LCD display
• Battery

Prerequisites

• Docker
• Pico Probe
• Raspberry Pi Pico
• CMake
• Compiler tools for your platform

Build - Local

To build locally, use the convenience script run-build-linux.bash. You can see the details of the build for setting up an IDE for more interactive development.

cd scripts && ./run-build-linux.bash linux

Build - Docker

Again, there is a convenience script run-build-docker.bash.

cd scripts && ./run-build-docker.bash

The benefit to this script is the output will be placed in the 'bin' folder, and it will be ready to flash to the Pico.

LCD Display

Using the Waveshare Pico LCD 1.14 (2 buttons + dpad style).
