I wish !!  My real job has been keeping me very busy lately.  I made the
mistake of taking 2 weeks of vacation.  Coming back is hell.  Have been
trying to figure out how to keep the power on to a small city while
reconstructing substation facilities.  I am down to bailing wire and duct
tape.

I agree!  Laying out stuff on proto/vector boards is challenging, fun, and
great learning.

Sounds like a great idea, and good experience as you say. Let us know how the 
module works out for you after you've used it for a couple of months or so.

That's the best way to start em out, when they're young and don't know any 
better.

WHAT'S THAT!!! STOOGES ON A VACATION!! NEVER!!! And the day after I sent that 
"useful" primer on the descending second formant too -- a true diy tutorial 
for the masses since it required no special tools or knowledge other than the 
ability to read and speak English. It may look like an easy job being a 
Stooge, all that eye poking fun, but actually it's hard thankless work. Nope, 
there are no holidays or vacations for a Stooge. It's a full time profession 
-- a true calling!

The only pitfall I can think of is that there are two separate GNDs on
the FX board, which *must* both be connected to the power supply.
