"Connect" to an atomic clock in space! GPS, DCF77

I have just finished the PCB design.
The PCB will fit into a Deltron 479-0160 enclosure.
I will make a final review on the design than send it to manufacturing.

I have upoloaded the menu state chart picture under the details chapter.

I have updated the block diagram and the schematic with a GPS module interface. My plan is that You can select on a menu which source You want to use to synchronize the local clock a DCF77 signal or GPS.

I can not help myself, I had to create a Hakaday bootscreen, uploaded some pictures about them.

Finally I have finished the schematic and uploaded to my project page. I expect only minor changes later as I progress with the PCB design.

I have posted the HW block diagram, working on the schematic right now.

I have added a few pictures from my prototype. I will further advance this one, redesign the PCB improve the SW, and design a nice enclosure.
