CrustCraft
This project aims to replace the existing thermostat of a G3 Ferrari Pizza Oven with an ESP‑chip based control system, thereby improving precision, responsiveness, and overall temperature regulation.
Happy baking! 🍕🛠️
Prerequisites
| Item | Description |
|---|---|
| ESP‑32 Dev Board | Any WiFi‑enabled chip with at least 4 GPIO pins will do |
| MAX6675 K‑Type Thermocouple | Only a K‑type thermocouple can withstand the temperatures required |
| 5V Relay Module | Atleast 10A |
| Power Supply | 5V / 2A AC-DC adapter |
| Connecting Wires | Silicone heat resistant wiring |
Clone the Repository
git clone https://github.com/vincvdwal/crust-craft/
cd crust-craft
Installing PlatformIO
VS Code Extension
Open VS Code.
Go to Extensions → Search for “PlatformIO IDE” → Install. Restart VS Code → PlatformIO panel appears on the left.
Project Configuration
Open the project:
Platform Command
VS Code Double‑click crust-craft folder or open > File → Add Folder to Workspace.
Edit platformio.ini (shown below – you can adjust as needed):
[env:esp32dev]
platform = espressif32
board = esp32dev
framework = arduino
; Optional environment for ESP8266
[env:esp8266]
platform = espressif8266
board = nodemcuv2
framework = arduino
Building the Firmware
Click the “Build” icon (checkboard) in VS Code’s PlatformIO toolbar.
The output will be displayed in the Build Log pane.
Success → you’ll see: "Build Done and an firmware.bin file under .pio/build."
Uploading to the ESP via VS Code
Press “Upload” (right‑hand arrow icon) in the PlatformIO bar → It will compile (again if necessary) and flash to the device.
Serial Monitor
Click the “Monitor” icon (plug + arrow) or Ctrl+Alt+M
Custom Configuration – Wi‑Fi Credentials
The firmware stores your Wi‑Fi SSID & password in secrets.h.
Copy the example or create a new file
cp src/secrets.example.h src/secrets.h
And replace the following with your Wi-Fi credentials
// Replace with your network credentials
const char *ssid = "WIFI_SSID";
const char *password = "WIFI_PWD";
Installing the filesystem
Use NPM to install all packages used for the website
npm i
Developing the filesystem
For developing the FS you can use the following command:
npm run dev
Building and flashing the filesystem
Create the ESP‑FS image
npm run build
This command writes all of your web assets (HTML, JS, CSS) into a data/ directory
Upload the image to the ESP32
In the PlatformIO toolbar, hit "Build Filesystem Image" to pack the data/ dir into a flashable filesystem image.
Afterwards, click "Upload Filesystem Image" to send the image to the chip.

Display
In the long run a capacative LCD screen might be used in addition to the WebSocket connection
