Not as cool as an original geochron but waaaay cheaper.

I’ve had this running for a week.  This was written up in the October 2017 issue of QST.

The Tom’s HW link is a little confusing.  It talks about a RTL SDR connected to the Pi when this has nothing to do with the clock.

I didn’t notice this was from CSI. I know them from xephem, which is an awesome cross platform  astronomy program.

That said...I wish I could justify buying a real geochron.  Those things are just iconic.  They make a cheaper black box version that you plug into a monitor, but the mechanical version is just awesome.

Gigaparts is selling a prepackaged version of this clock for an insane amount of money ($300).  You are starting to get into the realm of the Geochron cost.  Much cheaper to role your own...

BTW, one of the local hams made a similar comment about CSI’s astronomy software.  He said they produce good products.
