3D Printed Binary Watch

Prints (0)


A watch housing to hold a binary watch circuit. This watch shows the hour and minutes by flashing two LEDs in sequence to represent two 4-bit binary numbers. The left LED represents the 0's and the right LED represents the 1's. The first set of flashes is the hour, the second set of flashes is the minute. It has three pieces that pressure fit together very nicely. The body and the face pieces have an oval so that you can align the parts up evenly when the two pieces are together. The face piece has two tabs to help hold the circuit board in place. It also has pin holes to add your own strap.


UPDATE! I've added a circuit board template. Print the template and trace the inside onto the circuit board. Then cut/sand just to the line and then fine tune to fit.
