Use Raspberry Pi as a schedulable timer for GPIO hardware, configurable over the web. Depends on WiringPi.
This is the software for the pool timer project described at http://upon2020.com/blog/2012/12/my-raspberry-pi-pool-timer-why/
This should run on any Linux-based OS that runs on the Raspberry Pi, but you will have to manually put all the files in the right place, including creating the configuration file from the template.
If you run UBOS, it's much simpler.
- Clone this repository
Build the UBOS package with:
makepkg -c -f
Install the UBOS package:
sudo pacman -U rasptimer-*-any.pkg.tar.xz
Create a site that runs rasptimer:
sudo ubos-admin createsite --ask App to run: rasptimer
and answer the questions. You might want to choose '*' as your hostname.
