Source code and operating manual for a system that uses the Earth’s gravity to point telescopes at stars. It works on PushTo or GoTo equatorial mounts - uses an Android mobile phone App and a couple of stick-on sensors - cost is about AU$100 - assembly time is about half an hour using scissors and a screwdriver.
