All-Electronic Airspeed Indicator

[larry cottrill]

From the good people at Electronic Design magazine: An article describing how to build an electronic airspeed indicator providing linear output (such as 1 mv / knot airspeed) -- obviously, the calibration of the output voltage can be adjusted to suit the builder. Supposedly, this uses low-cost components, such as the Lucas NPC-410 silicon peizoresistive pressure transducer (SPPT). Ha:

Here's an Application Note (viewable/printable as downloadable PDF) which better explains the basics of using the Lucas NPC-410 pressure transducer (see pp 2 & 3):
