Just be sure you order the right one for your power supply & potentiometer. If you're using 12v (aircraft) power, be sure to order the 12v version, and if you're supplying 12 v to the pot (sensor), get the 0-10v range model. If you look further for different models, you probably need to avoid the ones that say they use an LM3915 driver IC. That IC has a 'logarithmic' characteristic, intended to directly display power (ex: audio amplifier) & will likely throw you a curve when trying to calibrate it.

Anyway, you could use one of these, and coupled to a LED display circuit y ou'd be in bidness. http://www.ebay.com/itm/221554609837?ssPageName=STRK%3AMEBIDX%3AIT&fromMa keTrack=true Here is the final product that I'm talking about. BTW, If you're not familia r with the Hall Effect circuitry you ought to check it out. This looks like a super fun project to build! http://www.barkeraircraft.com/files/AOA_rDisplay.pdf Mike Welch Moving back to Utah in one week. ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message kolb-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Kolb-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/kolb-list Browse Digests http://www.matronics.com/digest/kolb-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
