Since you mention it, I think my 2.2V figure was for green or yellow, not red which is lower. Blue is higher, like 3.6V IIRC.


The "20mA max" figure is to get a certain lifetime out of them. They'll produce visible light even at a few microamps, although you'd have to be in a dark room to see it down there.

What's an additional VIA among friends, anyhow?

I tried GIF but it did reduce the quality. Here's a PNG (see attached). I've also included the manual clocking circuit.
Is this one easier on the eyes?

Not for me. Gray letters on black is hard too, like gray on white, depending on how light or dark the gray is. Dark colors on black can be hard too. The hand-drawn diagrams on my website are .jpg; but after scanning them, I use the threshold funcion in Gimp to make everything either black or white so there's no gray scale info on the paper's texture or stray marks to take more memory, and then I select 100% quality so there's no artifacting. You still get good data compression when lots of pixels in a row are the same color (totally white in this case). This one for example is .jpg:



This would never do if I were selling jewelry or real estate or cars, but my non-commercial purpose is to just make info available and clear, not stylish. I have too much additional material to post to be taking time to learn to make it fancy. I use CAD for designing PC boards, but I have not liked the way any of them work for schematics, so I still do schematics by hand, and really only do full schematics for analog things, not digital.

Try white background with black text and symbols.

Here you go :

Very nice. Much easier.

Excellent .

BTW I have rigged up some 1.9v red LEDs at 3mA via 1K resistors. Seems to work well.
Down side is that I've run out of LEDs and breadboard room. I've got more LEDs on order, but think I might need to invest in a larger breadboard.

You should throw some green ones in there and you'd have a Christmas display.

I have some on order along with some blue and some orange ones, too!

Very colorful! There may be a new career awaiting you in interior design.

Very bling interior design! lol
