rotary encoder with LED ring?

W

Guest
I'm seeing a lot of devices lately that have rotary encoders surrounded by
rings of LED's. There are perhaps 31 LED's, surrounding the encoder knob in
a "fan" format that permits them to display knob position in a variety of
ways. An example of what I'm talking about is at
http://www.eventide.com/r2016/2016-Front.gif.

Can anyone point me to a supplier for these?

Thanks,

These are custom made for this company. Below is your only source for
these.

They may ask you to send them the unit for service. Many companies have this
policy. If this is the case, you will have to pack it up, and send it in if
you want it to be serviced. Call or email them to find out their product
policy.

You sure about that? I'm pretty sure I've seen them on other gear as well,
and I vaguely recall a conversation with a manufacturer (unfortunately I
can't remember which one, it was a year ago) who was talking about having
discovered them at a trade show.

Even if they are custom made, I'd be interested in who you think custom made
them. I have a product design in mind that would be helped substantially by
these.
 
Hi!

It's daft, but Newark don't stock them, and as Farnells parent company,
I would have thought they would? Farnell are based in the UK, but they
do export - check their website.

Yours, Mark.

Hmm, interesting: no manufacturer listed, and they say "while stock lasts" -
that is, it's an obsolete part. Wonder what, if anything, it's to be
replaced by? I'll check with Farnell and see if they provide any insight.
(I've also asked Eventide, though I'll be surprised if they respond.)

Hey..these things look pretty nice...but I have a kinda (heh, a little
bit more than kinda) newbie-ish question, because I'm not altogether
sure of exactly what an encoder like this is: Can this be used as a
potentiometer/rheostat? Or, maybe I'm just stupid, and it basically
IS a potentiometer.

Thanks,
Jacob
 
Hi!

You can use it as a pot - sort of - connect the encoder output to a
counter, then connect that to a DAC, that will give to a varying voltage
output, dependant on which way you turn the encoder, I'm not sure if
these have centering resets though, otherwise the counter could get "lost".

Yours, Mark.

The encoder provides a quadrature signal (like two switches that
operate in a synchronized fashion as you rotate the shaft from detent
to detent). Typically that would go into an ASIC or a microcontroller.
The LEDs are connected internally into a matrix. They can be driven by
a microcontroller (or ASIC). The microcontroller or ASIC could control
an external digital pot, or do something entirely different (provide a
PWM that could be filtered to provide 0-100% of power supply voltage,
for example.

So, they are really useless as a separate component, unless you are
programming a microcontroller or designing a chip specifically to use
this part.

Devlin also has the same part listed on their website -
perhaps they can provide some clues...
