Orbital Atomic Clock Downlink, or you know, a GPS.

An Arduino ProMicro using a GPS module to get the time, and then show it on a vintage NSA1166 LED display. Also: a bit of freeform :)

The GPS outputs standard NMEA messages, that are parsed to date and time, then offset for timezone and daylight savings.

The pinout of the GPS module is printed on the PCB, so wiring is easy peasy. The display was a bit harder, but i got it working with the excellent SevSeg library. The resistors are 330 ohms, by the way.

The most interesting thing about this code is probably my slightly hacky fix of the broken eu_dst implementation from avr-libc.

I'm entering this into the Tell Time Contest

I like that you threw in the circuit sculpture look too, just because. And bonus points for the bubble-top display.
