I'm looking for the very smallest -- panel mount -- LCD voltmeter. My
Google searches have been dissapointing. The smallest I could find is
about 2" wide.
This will be part of a 12V bicycle light system. It will mount in a
small box, probably on the handlebars. It's measurement range should be
about 8 to 20 volts.
A voltmeter is not complicated. I would think that one could easily be
made in a 1/2" square.
Does anyone know of a really tiny voltmeter?
Thanks for your help.
use a couple of LM3914 ICs and 2 10 LED bar displays.
You can make the scale whatever you want.For a 12V system,you don't need
over 15 VFS.
Do they make LM3914 in SMD? You could make a very small meter then.
