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.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

Sorry, the comment form is closed at this time.
Cool that you built it, but what makes a 200 clock low cost? Couldn’t I get the same with two 15$ digital clocks?
:O Is $200 cheap??
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!
