/diy/ - Do It Yourself

alright, third time's the charm.

Yeah, dot-matrix, not segment, I should have been more specific. Maybe OLEDs would be nicer to look at, like one or two of these:

A little mini-scope or a bar graph of current would be quite nice to have, as would an Ah accumulator, or even just a resettable peak current readout.
>What kind of aesthetics can you get out of a dot matrix anyways
Fast animation might be out of the question, but at 128x64 in a 30mm diagonal screen, the possibilities for aesthetics in 16x48 character boxes are plentiful. You like blackletter numerals? Nixie style thin and modern? You really want dem Slav runes? You got 'em. There are even modules such as Pic related with the top (or bottom) 1/4 in yellow and the rest in blue, so you can have brighter indicators for ranges or icons or whatever.
A full RGB screen is almost certainly overkill for a power supply. I could see it being nice for programmability, if one wants to glitch the input power to a chip or assembly or whatever, but that's another DAC or two and associated circuitry, so nah.
