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

Hi All,

Check out my new project:

I have finished the stage 2 video for the Hackaday Prize. It is an overview about the current status and main operation of the clock.

I have written some more details about the SW. The SW static arhitecture and coding considerations.

On the video below You can see on the oscilloscope how the DCF77 signal waveform looks like. You can also see how the two separate clocks are snychronizing to the DCF77 signal.

GPS signal processing high level design description added.

I have updated the detailed description with a video about the menu. Further videos and design description will come.

I have added the detailed description of the temperature measurement algorithm.

I have just finished mounting the components on the first PCB. I mounted the populated PCB on a Deltron enclosure. Uploaded some project pictures about it.

I have just received the new blue PCBs, I will have 2 PCs manufactured in  red too next week. The PCB is nicely fits into the Deltron enclosure. Beauty.

Working on the UART interface driver of the GPS module right now. Just received the first GPS sentence containing the UTC from the PmodGPS module. Still have to work on handling the framing and overrun errors..., new PCBs also on they way, lot of work ahead...
