LOL Clock redesign

This is a remake of robaux's LOL Clock (https://www.thingiverse.com/thing:2219658). A new back piece 18mm thinner than the original has holes for the power socket and buttons.
A new circuit design has been done that uses two LED constant current drivers and five MOSFETs row drivers. There are two PCBs. One to hold all the LEDs (board is cut in half so that it can go in the case) and the second board holds the Arduino Mini, DS1307 RTC, DC-DC Buck convertor, Constant current LED drivers/shift registers and some buttons to set the time.
All Eagle files and Arduino sketch have been included along with the new back STL file. I made my boards using the toner method. The board contains SMD components because that is what I had on hand.
