Building an electronic Angle of Attack indicator

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.

EAA web site says June 07 Sport Aviation Magazine, but I thought it was
more recent than that.

That's a nice set up. It shouldn't be too hard to add an audio alarm
or shaker. I just hope the pitot tube isn't heated.

Speaking of which, I have a heated pitot tube head
If anyone is in need of one, drop me a note.
