Schematic for a Binary watch with a small 14p PIC microcontroller.

Also includes a button and ICSP header for in circuit programming.

You can power this from a small battery.

You might even use the SLEEP instruction to save power.

The 32768 xtal is a typical watch xtal.

You can change the Led Resistors values for your leds.

I've used 2mA low current leds.

Vpp programming voltage is isolated from powersupply by a Diode.
