reflow-controller

pi pico project to control reflow oven

This project is currently under very heavy development, so expect some bugs as of now while i do more testing

how to use

• download release zip
• upload all files in the to the micropython device
• check the wokwi diagram below for wiring diagram, and add a toaster oven on the relay that will be the actual oven

wifi connection

• currently wifi is disabled due to wokwi issues, these will be fixed soon(tm)
• add your wifi network in the file networks.json in this format, and it will automatically connect to the 1st network:

{
	"ssid":  "your-wifi-name",
	"pass":  "your-wifi-password"
}

wokwi simulation

• this project can be simulated in wokwi here is the link https://wokwi.com/projects/405794574081822721
• wokwi is not 100% accurate so wifi features have been disabled, also there is no toaster oven in wokwi

temperature sensing device

• it is recomended to use a thermocouple because it is easy to find high temperature thermocouples, code coming soon for this
• a ntc thermistor can also be used but can have issues at higher temperatures

solder pastes

the currently supported solder pastes can be found in profiles.json

all lead-free solder pastes have the "LF" marking at the end of the name for easy differentiation, if you open a PR please include this if the paste you are adding is lead-free

if you would like to use a solder paste not currently included in the project please do one of these things

1. open a github issue - please provide the name of the solder paste and preferably a link to a datasheet (preferred)
2. make your own profile like the example profiles found in profiles.json and open a pull request with the name of the paste and a datasheet
3. message me with the contact info found on my website https://whatware.net/about
