"empirical" learning...
01/01/70 00:00
read the material...
01/01/70 00:00
I believe he is using a MOSFET here
01/01/70 00:00
kit
01/01/70 00:00
It is DC output
01/01/70 00:00
POOF BOOM
01/01/70 00:00
what about this circuit?
01/01/70 00:00
IRFZ48N and a circuit, this one can fit?
01/01/70 00:00
A little bit easier link

do you need it that bright
01/01/70 00:00
Bar and some info
01/01/70 00:00
sure you can
01/01/70 00:00
Hard to adjust intensity by changing voltage
01/01/70 00:00
Simple scheme...
01/01/70 00:00
Very nice!

HC32 and not KTC32

maybe another CI?
01/01/70 00:00
Yes most hc is ok

Same HCs to switch ULN2803?

01/01/70 00:00
you can - wth a caveat

Can I ask a color question?

Interpolate in RGB or HSV but not in your tabulated index.
01/01/70 00:00
linear interpolations...
01/01/70 00:00
Standard interpolation
01/01/70 00:00
that depends
01/01/70 00:00
right subject
01/01/70 00:00
your premises are wrong
01/01/70 00:00
If you answer a question...
01/01/70 00:00
Just tests, no MOSFETs yet...
01/01/70 00:00
The ULN2803 will ruin your colors!
01/01/70 00:00
when doing color
01/01/70 00:00
miss the point... the point is the color generation...
01/01/70 00:00
Help with what?
01/01/70 00:00
already answered
01/01/70 00:00
Have you seen my link?
01/01/70 00:00
Yes, but dont helps...
01/01/70 00:00
as usual
01/01/70 00:00
not "SPECIFIC, SPECIFIC, SPECIFIC"
01/01/70 00:00
Use another look-up table...
01/01/70 00:00
Thats it!
01/01/70 00:00
Copy from a professional solution...
01/01/70 00:00
Youtube has some nice videos...
01/01/70 00:00
you've got it wrong and what are you doing
01/01/70 00:00
I care Erik!
01/01/70 00:00
why are you "going through steps"?
01/01/70 00:00
Kai videos?
01/01/70 00:00
Already been told
01/01/70 00:00
HSV
01/01/70 00:00
Now I'm confused
01/01/70 00:00
Still never telling what you do want
01/01/70 00:00
you are going for an intensity ratio ...
01/01/70 00:00
I see no contradiction...
01/01/70 00:00
I think it was incrementing of the index that was the proble
01/01/70 00:00
Chico, are you getting it
01/01/70 00:00
Words
01/01/70 00:00
He should have enough information now...
01/01/70 00:00
that is often the problem ...
01/01/70 00:00
Words fail me...
01/01/70 00:00
How to add
01/01/70 00:00
You don't have paletted device so stop thinking about index
01/01/70 00:00
only 125 colors
01/01/70 00:00
Smooth? Sudden? This make no sense!
01/01/70 00:00
I'm tired from guessing, Chico...
01/01/70 00:00
So you haven't read what we have posted?
01/01/70 00:00
Thats it Kai...
01/01/70 00:00
place my 125 unchangeable colors in a nice sequence in this
01/01/70 00:00
Lacks words for me!
01/01/70 00:00
You need more levels.
01/01/70 00:00
See previous suggestions!
01/01/70 00:00
only 32 words
01/01/70 00:00
what is "nice sequence"? and for what purpose?
01/01/70 00:00
A Color Sequence
01/01/70 00:00
Gives color jumps
01/01/70 00:00
Missing backslash in previous post
01/01/70 00:00
Look at the example cited earlier
01/01/70 00:00
not a good one
01/01/70 00:00
Starting point?
01/01/70 00:00
my thought is
01/01/70 00:00
Did I get you?
01/01/70 00:00
sort of
01/01/70 00:00
Thanks!
01/01/70 00:00
You are so full of yourself...
01/01/70 00:00
"web safe" colors available in standard VGA color palette
01/01/70 00:00
right, you compensate for this by ...
01/01/70 00:00
Note that candela hides the eyes spectral response
01/01/70 00:00
true, and
01/01/70 00:00
But he doesn't want his solution to be better - just differe
01/01/70 00:00
I give up suggesting better and simpler ...
01/01/70 00:00
with "binary weighing" he gets 32738 colors
01/01/70 00:00
Number of colors
01/01/70 00:00
for a LED sign: none
01/01/70 00:00
Solve modulation first, then bother about constant-intensity
01/01/70 00:00
not if you do as I suggested
01/01/70 00:00
You'll see a lot if slow-stepping changes
01/01/70 00:00
How naive I was...
01/01/70 00:00
I do not know, but ...
01/01/70 00:00
I still say...
01/01/70 00:00
Everything depends on needs - simplification often ok
01/01/70 00:00
Gamma
01/01/70 00:00
If I were Chico...
01/01/70 00:00
Another Color Sequence...
01/01/70 00:00
Yet another sequence...
01/01/70 00:00
another (better) approach
