I completed the PCB for the Word Clock last night, but I slept on it for the night before submitting it. It’s a good thing too, because I thought of something else.

Once I went back to it I thought that I should probably add in a few additional hookups for outputs. I don’t know what I’ll be doing with the other 2 boards once I get them. I don’t know what features I might want to add in a future revision. I might go ahead and add those 4 corners LEDs; maybe even a speaker for an alarm. Whatever the case, I’ll need some additional outputs from the ATmega. I also added an additional Vcc and GND connection to the board in case I add something that needs power. You never know.

The schematic didn’t change except for the addition of the 1 and 2-pin headers.



Here’s the final board:



I then submitted it to OSH Park. Here’s the render:



Lookin’ good! 3 boards for $40.55. That’s only $13.52 each. Awesome.
