[time-nuts] Needed: The Real Serial USB Fix

[Chris Albertson]

There was one just posted here using the Atmel AVR chip.  He used a total
of about $12 in parts.  You could use a TI "Launchpad" if you don't like
soldering and still spend less than $20.   And as was said, no OS at al.
 It is simply not required for such a simple job.

If it were me, I remove the LCD display.  I don't see a need when everyone
today has a phone.  the little AVR chip can bit-bang a UDP packet once per
second and put it on your wifi router.  That cuts the parts cost by 1/3rd
and the display will be where you can see it, on the phone or computer.
