Toaster

A simple web dashboard for my SMT reflow oven (T-962 + Raspberry Pi)

First time setup

1. Install Raspberry Pi OS on your Raspberry Pi
2. Setup access to your Pi via SSH with a private key
3. Run npm i (npm install) locally (development computer) to install dependencies
4. Run npm start locally to deploy the app to your Pi

Development

Develop alongside RDT

1. Run npm i in both the toaster and rdt directories to set them up
   • Run npm run watch in rdt to build continuously
2. Replace dist package in node_modules/@cinderblock/rdt with a symlink to your local rdt/.dist directory
   • Linux

     rm -rf node_modules/@cinderblock/rdt
     ln -s ~/path/to/rdt node_modules/@cinderblock/rdt

   • Windows (PowerShell, ensure "Developer Mode" is enabled)

     rm -r -fo node_modules/@cinderblock/rdt
     $null = New-Item -ItemType Junction -Path node_modules/@cinderblock/rdt -Value ~/path/to/rdt/.dist

Hardware Connections

Following the hardware improvements from Unified Engineering, we also add a Raspberry Pi Zero W to the oven to control it. The lpc-flash library can also handle flashing the latest firmware on startup to ensure a consistent state.

By adding a U.FL connector to the Pi, we can use a "U.FL to SMA adapter" to add an external antenna to the oven. This allows us to place the Pi inside of the oven, and still have a reliable WiFi connection.
