If I were looking at a similar project, I would consider using a  

microprocessor, 7-segment LED displays (or a backlit LCD for good  

sunlight readability), and two quadrature jogdials. It's not a simple  

solution though, and I'd be hesitant to encourage you to attempt this  

solution as a novice due to the combined software and hardware nature  

of the microprocessor...



Total electronics cost (assuming you have all the required tools and  

a programmer) in the order of $15, then you'll need an enclosure of  

some sort. Maybe another $15-$20. Certainly do-able for waaaaay less  

than $400.



Hope this inspires some other answers, hopefully with a simpler  

solution that would make a good project for a beginner

Very simple from a hardware perspective, and the code for the  

microprocessor is not too hard. However, I'm not a noob (BSc in  

Electrical Engineering  ), and I have all the required tools on hand!

 Hi,



 I am interested in building a simple, small, bright LCD display  

 that can increment numbers with the twist of a knob. I would like  

 to build a 4 digit and 3 digit versions, to represent pattern  

 altitude and heading, respectively. Put it in a small enclosure and  

 mount on my dash.



 Pattern altitude - knob changes in 100' increments

 Heading - knob changes in 10 degree increments. Would be nice to go  

 from 0 to 360, then roll back over to zero (0).



 I know you knowledgeable electronics guys are thinking this is  

 stone simple, but.... I'm a noob. I don't know which parts to mix  

 and match to make this happen. And while having googled lots of  

 stuff, I am still unsure how to pick the right parts to make this  

 work. So if someone in the know could suggest the right combination  

 of parts it would be most appreciated.



 Here is a commercial version that inspired my request here. But  

 sweet jeeezus, at $400 that is just plain outrageous for what I bet  

 cost maybe $50.

 Thanks in advance!

Etienne,



Thanks for your note. It is educational. I'll keep the info in mind.
