[time-nuts] Time Code generator

[jimlux]

apropos of the conversation

I seem to recall someone having built a PIC or Arduino based widget that 
  was a IRIG generator/receiver.. you'd hook up an external 10 MHz 
source (something that any time-nut would certainly have.. the problem 
would be selecting which one to use).  I think it used a USB or serial 
port to do the "control" function (i.e. setting the time or returning 
the decoded time)

I also ran across a real small FPGA implementation about a year ago, but 
I can't find it now.  I was looking for a decoder I could drop into a 
Xilinx design to be an "enhanced" 1pps sort of thing.
