[simpits-tech] Circuit question - plus another for Gene

[Brian Sikkema]

I had thought of that, too, but this is something
that will be cycled quite a bit, and I'm afraid of
things wearing out/breaking, plus it would be a lot
more involved on construction than I would like.

As for the PIC route, that's kinda what I was
expecting... In fact I think I have a BASIC stamp
around here somewhere not being used... gonna have to
look up the spec sheets and see if that can do it. I
bet it can...

And Gene, what if something were truly /back/ lit.
I'm gonna have the light bulbs behind this panel.
Shouldn't be an issue, right?

 If your more mechanically inclined, and depending on
your room available with your design or whatever it
is your using.

you could have some momentary switches (or opto
switches) be pressed (blocked/not blocked) based on
the position of the slider.

Hey guys, quick q for ya.

I'm thinking of building a circuit, and basically
what I need is this: I have seven LEDs that need to
be lit up in sequential order as a linear pot is
moved. So basically as you slide the pot from one end
to the other, the LED's all light up (only one lit at
any given time) from one end to the other.

Idealy it could be adjusted so each LED lights up at
a specific resistance, as I need it to be a little
non-linear at spots - i.e. I for a couple, the pot
would need to be moved 1/2" to move on to the next
light, then for others it would only need to be moved
a 1/4".

Somewhat confusing, I know... but it seems like it
should be doable. But I'm no EE so I dunno how.
Simpler the better, though. Not looking to sink a
whole lotta money or time into this project.

As to my second question, Gene how thick are those
backlit panels you make? Do you think you could make
one roughly 1/8" thick, or would that be too thin?
