ESP32-S3 Wifi Boat Controller

This is a work in progress.

Project Overview

I want to build a fully functionning wifi-controlled 3D printed air boat from scratch.

The boat contains an ESP32-S3 board which is used to control the boat's motor and rudder using HTTP requests.

You can send POST requests to the /boat endpoint to update the boat instructions.

### Send boat instruction
POST http://192.168.4.64/boat
Content-Type: application/json

{
  "motor_speed": 255,
  "rudder_angle": 90
}

The board runs a web server that can be accessed as long as you're on the same WiFi network.

I may investigate using AP mode or bluetooth connectivity to make it easier to share wifi network details eventually but at the moment, you have to set WIFI_SSID and WIFI_PASSWORD environment variables at build time.

Bill of materials

In Progress.

Printing the boat

In Progress.

Assembling the electronics

In Progress.

Flashing the firmware

Build dependencies

You will need:

• Rust version 1.80 or latest
• Python version 3.X with pip and venv (to build esp tooling)

If building on Windows 11, you will probably need to download this driver: https://www.silabs.com/documents/public/software/CP210x_VCP_Windows.zip

We'll use espflash to push our binaries to the ESP32-S3 board.

cargo install ldproxy
cargo install espup
cargo install espflash
cargo install cargo-binstall
cargo binstall cargo-espflash 

We'll use espup to setup the proper toolchains for the ESP32-S3 board.

espup install

Flash the binary

Connect your ESP32-S3 device using the UART port to your PC.

cargo espflash flash --monitor
