VFD + LCD = (sectionally-) selectable color filtration
Yeah, Got this ancient VFD, 40x2. I do like the nice glow these things have, and the sharp contrast... And the ability to use color-filters...
I tried it out once, throwing an old laptop panel in front, with its backlight/back-panel removed... it seemed to do quite nicely. I kinda dug the 3D aspect of it, as well... the "display" being more of a window... the overall shape being somewhat more "square" and hiding the fact that the VFD is distinctly rectangualar... Could throw other things back there, too, LEDs, whatnot. Even stencilled lightbulb covers, and selectable color-filtration for those as well... even lighted circuitry... Who knows, maybe color-filtered Nixies... or those 7-segment incandescents... The list goes on. The depth... I kinda dig it. The irony(?) of the ancient and new technologies; the new being capable of *all that* the old is doing, yet being used for little more than could be done with a simple color-wheel. Awesome.
(And, I've already been using an ATtiny85 to drive laptop displays with nothing more than a couple TTL XORs, its limited memory and slow-refresh lends itself perfectly to a project like this. #my very first binary-clock)
Also, found some recent inspiration from #HD44780 LCD Graphics that *might* be implementable on this VFD. This cat... holy schmoly.
As far as *what* this UI will be for...? That remains to be determined.
(oh, and maybe something about a clear-capacitive-touch-overlay? Or a light-pen!)
Have been wondering what'd happen if an LCD is cut horizontally (e.g. with a glass-cutter), might lend itself well to better-fitting the VFD. I think some displays could handle it, depending on the design)
Possibly have a lit/"white" background (somewhere a little below the LCD for 3D/floating-effect) and use a *portion* of the display for text/graphics... not sure.
