I threw together a nightly build server.
http://www.casler.org/meshtastic/nightly_builds/
This builds whatever is in the meshtastic_device master branch every night at 2am PST. It should be available by 3-4am PST.
These are not blessed builds. These are “pre-pre-alpha”. Made that for my own use and sharing it here, just because storage and bandwidth is nearly free.
