Toy project for turning a laptop cooler into a "smart" cooler by incorporating an Arduino Pro Micro that presents itself as a USB HID device and communicating with it through USB. Naturally, the code here is highly specific to the laptop cooler used!
- device: the Arduino Pro Micro embedded code to monitor & control the laptop cooler through USB
- shared: shared code between
deviceandtray. - tray: a
libindicatorbased system tray driver that usesrusbto communicate with the device.
Please check out each crate's README for more details.
My biggest pet peeve with laptop coolers is that they are not communicating with the host in any way and that makes them inherently dumb. This bothers me the most when it comes to the host going into sleep while the cooler stays on, like when closing a laptop's lid. The initial motivation for this project was thus to accomplish one simple task: turn off the cooler when the host is suspended and turn it back on when the host resumes. I've actually done that before for my old cooler using a Digispark ATtiny85 board and V-USB through SoF (Start of Frame) packet counting.
However, the new cooler I got and used in this project had all these additional buttons and features and so I figured I might go further and replicate the hardware controls into software and write some sort of driver to control the device from the host.
The device crate uses custom cargo configuration therefore building it must traditionally be done from the package's directory. Alternatively, invoking cargo from the workspace root can be done using unstable flags cargo -Z unstable-options -C device build.
