A Low Cost Sidereal Clock.
A clock that displays UT(Universal Time) and LST (Local Sidereal Time) is a useful device to have in an astronomical observatory. Using the Arduino open source platform it is possible to build a sidereal clock for less than $200.
Cool that you built it, but what makes a 200 clock low cost? Couldn’t I get the same with two 15$ digital clocks?

Hey! Get an eZ430 Chronos watch for $49 from TI and the OpenChronos firmware, the sidereal time is already coded!

I have been looking for an enclosure exactly like that one. Would you mind telling us where you got it?
Oh- VERY nice job on the clock!
Thanks!
