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
