DRE@M, our FIRST Robotics Team at MADE For Kids, makes and sells these clocks as a fund raiser.  The clock design is evolving, but each clock features a visible 12:1 planetary gear system to which the hands are attached, and which is controlled by a programmable Arduino and a real-time clock chip.  Customization to the design is possible for additional charge.
 
At this time, we are accepting pre-orders, so that we can plan capacity for manufacturing.  Each clock is made by hand at MADE, except for the PCB, which is a custom board manufactured in China.
