Teensy Fan Controller

Documentation: https://mstrthealias.gitbook.io/teensy-fan-controller/

A PC fan controller with temperature sensor input, for Teensy 3.x USB Development Board(s).

Supports up to 6 fans (4pin/PWM), and up to 5 temperature sensors. Each fan may individually operate in PID, temperature-percent table, or fixed-percent control modes. Configuration is saved onto the device, and software is not required other than to configure the controller.

Documentation

The project is documented using Gitbook, and accessible at https://mstrthealias.gitbook.io/teensy-fan-controller/.

Releases

• v0.1.0
  • Firmware (Teensy 3.2, 3.5)
  • Configuration UI (Windows 10)

Hardware

• Prototype - Simple PCB: requires PCB fabrication (gerber files provided) and through-hole soldering
• Prototype - Breadboard: breadboard example with a single fan/single sensor
• Prototype - Hand-made (Schmart Board based): uses over-the-shelf components (OK for single fan/single sensor builds)

Software

Qt UI

Teensy Fan Controller UI (Qt5): provides a user interface to configure or monitor the fan controller (only needed for initial configuration).

Linux Kernel module (hwmon)

Fork of liquidtux: Linux kernel module for reading temperatures and fan RPMs using lm-sensors or psensor. Tested on Ubuntu 18.04.
