Vector ring indicators for Volume, tone, etc..

[Gledison]

Hey Guys,
I´ve just finish another "toture time" finding an idea for the graphics design for my sea urchin. after some work i managed (by luck) to create a ring indicator for the pots. im just learning how to use inkscape/illustrator and would like to know if someone could help with some template which i can be based on in the future.
Does anyone has also tried to have small LED indicators for the volume/tone/etc pots?
Thanks in advance for any help!

I had these archive on a USB key. Might help some.

Might be fun to make a nice DIY template for basic knob sizes.

You mean something like that ?

Here's some:

There's a web site somewhere that generates them also, but I can't remember what it is.

Hey Cody, thanks a million for linking to your Illustrator files. I've only got Illustrator on my computer at work, so figuring out indicator rings isn't something I've been able to accomplish during my lunch hour so far! These are all really cool options.

Thanks a lot mate!

Never It's just the first or second result given by google, I had never considered using LED rings for pots on a pedal. They must take an awful lot of space. They could be fun for effects with just one pot though.

Those are cool, but you have to have an MCU with SPI to work with them. They're designed to work with rotary encoders too, which pretty much limits them to being used with some type of processor on the knob side too. Though, you could probably ignore the rotary encoder connections if you were running to an MCU with an A/D converter and then output to the LED section from there.

Glad they worked for you.. I do not want to take credit for them since I did not make them. I picked them up months if not years ago. I just archive things and forget I have them. When someone asks for something I usually look at my archive and post what I have.

Pretty expensive solution these boards. Just imagine a 16x16 knob box. (OK, 8x8 or 4x4.)
Is it possible to do it cheaper if there is more than one LED ring and more than one encoder?

[RobA]

The parts are cheap enough. Here is a link to the main part's spec sheet at mouser

Here's the part http://www.mouser.com/ProductDetail/Texas-Instruments/TLC5925IDWR/?qs=sGAEpiMZZMsE420DPIasPqeXS8%252blRWnW9wnwO8MoeK4%3d
That's the SOIC version. They have SSOP and TSSOP too if you enjoy more soldering torture.

It looks pretty slick. The Sparkfun link above has some sample Arduino code too. It actually looks like it would be pretty easy to use this. I picked up some linear LED arrays a bit ago and I may have to order a couple of these chips to play with. The TLC5925 looks like it takes care of nearly everything and really reduces the parts count. It even looks like you can chain them together to get more LED's.

OK, I only saw that one board is $15.95...

Yeah, the price of the board is kinda crazy -- not sure why it's so high.

Dear engineers:
It could
Be possible to create a layout where , lets say, 4 small leds would light depending on the resistanc level of the pots?
