Ed,
Do you have a printed circuit board on your air fuel mixture
monitor. I would like to have a unit ready to go. I like
your idea using all those LED'S.

I am in the market for one as we speak.

Sorry Paul,
    I do not have a print circuit board for the circuit.  I considered
making one as they appear fairly simple for this type of circuit, but just
did not get around to it.  I must admit soldering 40 leads to those LEDs and
then to the rest of the circuit got tedious real quick.  Besides for some
strange reason, I don't seem to be able to focus on those tiny components as
well as I once did {:>).

   I ended up using the 30 gage insulated wire wrap for the LEDs but it was
really a little too stiff. But, large gage wire just make it too congested.

Can you send me the pin outs for the chips? I can do a PC board with Tango in
an hour or so and get some made. How is it working lately?

BTW What is the status of your airplane? You have got to get it tuned up 
so you can enter the  NC to Oshkosh race and win the Everett Hatch memorial 
prize. Over $400. Do you think it can average over 200 MPH?
