GPS Clock

Enclosure for a super accurate Arduino GPS clock. Basic description and sketch here: learn.adafruit.com/arduino-clock/software?view=all I expanded this with a charger, Lipo, on/off switch and a touch toggle switch. The display is bright enough to be visible through the printed enclosure so have fun with different colors for the outer shell. Sand the contact areas on the inner part so that the shell slips smoothly over it. I printed this in PETG for dimensional accuracy but PLA should be fine. Shell prints without support, ad a brim for adhesion. Power on/off is wired to GND and EN on the powerboost board. Toggle switch powers the Metro mini and display together. Just powering on/off the display doesn't work but both together come on immediately anyway. GPS is powered as long as the Power boost charger is on. Added the Lipo to be able to carry this around as GPS signal inside the house may be difficult to find at any given time. The display seems to draw a fair amount of current so the lipo lasts about 36 to 48 hours on a full charge. Had an antenna cable around, but this seems not to be necessary.
