New Earth Time (NET) digital clock in recycled retro-modern case using PIC16F627A

Ever get confused by GMT, or just wish you had a cooler way to keep track of time?  Build a New Earth Time clock!  Using a PIC microcontroller, some code, and a couple discrete parts, you too can have a unique timekeeping device to keep on your desk.

New Earth Time (NET) is an idea for a global time standard.  Like Greenwich Mean Time (GMT), it is the same “New Earth Time” everywhere on the globe at any instant.  Unlike GMT, NET counts time in Degrees and Minutes so as to not be confused with your local time (which is still counted the same way you’re used to).  You can read all about how New Earth Time works at their website, .

It seems like a cool idea to me, and what better way to support the idea than to build a clock and start using New Earth Time!

Step 1: Parts

You can see my prototype NET clock in the picture to get an idea of what’s involved.

1x – PIC16F627A Microcontroller
1x – 32.768kHz Crystal (Mouser 815-AB26T-32.768KHZ or equivalent)
2x – 22pF Ceramic Capacitor (or 1x 22pF and 1x 0-56pF Variable capacitor for tuning)
4x – 10k Resistor
7x – 100 Ohm Resistor
1x – 4.7k Resistor
5x – 1k Resistor
5x – 2n3904 Transistor
5x – Common Cathode 7-segment Display (Mouser 512-MAN6980 or equivalent)
2x – SPST Momentary pushbutton switch
1x – Round LED, modified as described in Step 2 (Making the degrees LED)
