Wrist-Watch for Nerds

This wrist watch, made by Elia, is a binary based wrist watch i.e. displays time in binary digits and is small in size. The yellow-color LED’s for the digits perfectly suits the watch and also is compatible with the OSHPark PCB, which is a custom PCB-board manufacturer. Another interesting fact about the watch is the strap which is paracord bracelet along with a buckle. The steps to make the buckle are easily available on the internet. The watch is powered by the PIC microcontroller which comes with a SSOP package.


Along with the PIC, it also has an on-board ‘real time clock’. Moreover, it also features a sleep mode in which there is no display and consumes only 150uW of power. There can be additional power saving by pulling the remaining pins to either VCC or GND. However this functionality is not yet available in the current PCB. Overall, the watch is really good and a must try for those people who have just started learning the PIC microcontroller. Moreover, if you are considering to make this watch yourself with the same schematics, I would advise you to cover the PCB and the LED’s with a good quality glass.
