It's been a while since I've picked at my pile of transistors or posted here, but here is an idea for a mix indicator light for easy level monitoring.
I'm thinking I'd like to build a nice level indicator in the form of 3 lights. If the level is below a certain threshold, say .33vDC for example, then the green light will be lit. If the level is between about .33V.DC and .66vDC then the blue light will be lit, and when the level is above .66vDC then the red light will be lit.
Does anyone have any ideas about how I could lay this out or how to really get started? I'm really trying to knock the rust off of the brain cells on this one, so simple is best!
