Default Re: Driving a piece of electroluminescent tape in lieu of a magic eye

Or an arc of small green LEDs behind a translucent screen, with that old favourite the LM3914 IC driving them to give a pseudo-representation of a 270-degree 'meter' scale?

[The LM3914/15/16 - though an IC - counts as vintage! NatSemi released it in 1980!]
