totally-not-a-space-heater

A project attempting to control a folding@home rig based on room temperature with a microcontroller

⚠️ IMPORTANT NOTICE ⚠️ This project DOES NOT work with FAHClient v8, Please install v7 to use

Required Materials

The following parts are required to build:

ESP32 Micontroller (Other MCUs may work but will NOT be supported)
2 Buttons
16x2 Character LCD (Based on HD44780) using I2C interface (PCF8574)
DHT22 Temperature and Humidity Sensor
Wires to connect circuits together (Breadboard optional)
Micro USB cable capable of Data transfer

Connecting Components to ESP32

Normally Open Terminals of one button between GND and Pin 12 (Temp Up)
Normally Open Terminals of one button between GND and Pin 13 (Temp Down)
For DHT22, + to VIN, Out to Pin 4, - to GND
I2C LCD, GND to GND, VCC to VIN, SDA to Pin 21, SDL to Pin 22

Required Environment for Programming MCU

Arduino IDE
Drivers for your particular MCU (Varies depending on what you get)
Libraries below to be installed

Required Arduino Libraries

Button2 by Lennart Hennigs
DHT sensor library by Adafruit ⚠️ Windows Users Please do NOT install v1.3.3 or newer if you have ESP32
LiquidCrystal I2C by Frank de Brabander

Required Environment for controlling Folding Rig(s)

Python3 environment (Development done on 3.10 and 3.11, 3.13+ will NOT work, 3.6+ should work but not tested)
pyserial package (Install with pip install pyserial)
Drivers for your MCU (Varies depending on what you get)

Project Goals

Start and pause Folding based on room temperature
Vary heat output based on heating needs
Expand to multiple machines
Connections over Serial
Connections over Wifi
Connections over Bluetooth
