Has anyone built an electronic angle of attack meter kit. It seems to
be something that would be easy to design but beyond my feeble
electronics background.

I have seen the products that are out there and they are simple
differential pressure gauges and are expensive. I don't like the
round differential pressure gauges that many of the companies offer
for this kind of system. I was wondering if there would be a way to
put something together that would light up different color LED's for
the different levels of lift that we could build at home without
having to pay out hundreds of dollars for a prebuilt one.
Buy an electronic differential pressureindicator and put a bar graph
on it.

Not cheap - new Setras are about $400 but they are available surplus
occaisionally at good prices. You want 0-5 volt, not 20ma outputs.
