KABtronics was asked to make a display showing days left for a team of engineers.
A PIC processor based clock was designed that allows displaying time or days left. A precise TCXO (temperature compensated crystal oscillator) was used for high time accuracy. A 1 Farad capacitor provides power loss protection.
A single PCB, 9.9 x 7.9 inches fits in a 10x8 display shadow box. Red Acrylic can be cut to fit behind the glass at the front of the shadow box.
The operating manual is done, the contruction manual has not been completed at this point.
