FanBoy

Open Source PWM Fan Controller

Summary

FanBoy is an Open Source DIY approach to providing a cross-platform PWM fan controller with temperature sensor support that can easily be modified to fit your needs.

Features

Four discrete PWM channels
Supports multiple fans per channel (up to 40 W max. total power draw), auto-detection for disconnected fans and RPM sensing
Two temperature sensor inputs
Supports standard 10 kΩ thermistors
Based on well-known Arduino platform
Uses the ATmega32U4 of an Arduino Leonardo as MCU for minimal development overhead
Multiple operation modes per channel
including fixed duty, linear and target temperature ¹
Persistent data storage
Stores all settings as well as last operation mode CRC-protected in EEPROM
Simple serial protocol
Comes with a simple static library for communication abstraction as well as a command line utility for configuration

¹ Planned but not implemented yet

Components

This DIY kit consists of multiple components that are reflected as subdirectories:

Folder	Description	Platforms
pcb	PCB that can be manufactured very cheap via common PCB fabrication services	Linux, Win32, Mac
firmware	Firmware based on Arduino Core	Linux, Win32, Mac
libfanboy	Static C library that implements serial interface between host and FanBoy	Linux, Win32, Mac
enclosure	Simple 3D printable enclosure that fits a 2.5" drive slot	-
fanboycli	Command line client based on `libfanboy`	Linux, Win32, Mac

ℹ️ In addition to these components there is a Qt based GUI called FanMan.

Contributing

Code

The code uses 4-space indentation and K&R style bracing. Usage of Arduino libraries is kept low to keep the possibility of switching to avr-libc. Code documentation is done inline (headers) using Doxygen.

Bugs / Features

Pull requests are always welcome. Feel free to report bugs or post questions using the issues function on GitHub.

fanboy's Issues

Would there be interest in updating this with a MicroFanboy?

I made a much smaller version of this to fit with my smaller available size available to me, keeping all of the same functionality but reducing it to 2 fans, wondering if you would be interested in a patch to add this version to the official one? I could submit it in Fritzing format if you would like?
