 |
|
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!
