Hi all, sorry if this is in the wrong area, first time here.
Looking to get 115mm or 120mm OD addressable LED rings, striking out everywhere I look. Is it possible to have these custom made? If so, where do I go for this?
Thanks
Scott
Did you look on eBay?
Need more information what you mean by addressable.
How many leds?
Not sure if any of these meet your requirements, perhaps you can design your own.
.
You can always talk to an engineer.
How many LEDs do you want in the ring? What kind of spacing? How many degrees apart? How far from the edge?
What kind of connector?
Solid ring, or hollow?
Here's a rough layout showing 20 LEDs.
I just mean that it can be controlled through arduino, not sure of another term sorry.
I need something that is outside diameter 115mm or 120mm max, probably equates to about 36 or 37 leds. I don't mind having them custom made or even making them myself, just don't know where to start.

As many as will fit in a ring that is OD 115mm and ID ~106mm.
Do you mean the connector to connect to arduino? I was going to solder right to the board.
Probably a solid ring for a "plasma" look.
Thanks!
Ring concept with 30.
I'd rotate each LED so they're all oriented the same with respect to the edge and the cap placed in the same spot.
I could design that for you. Take a couple hours.
Looks like for those dimensions, thru hole LEDs will be needed.
These are actually in stock
Crummy datasheet - can't tell the pin spacing. Or the hole diameter needed.
Determining even placement will be critical to a symmetrical view
Looks like AutoCad is needed, but there would be no Gerber output file.

Don't need autocad, just some math in an excel spreadsheet, with rotation/position values used in Eagle.
I did that to layout 60 in a circle one time.

How can I get 4 of these?
That one does not have RGB LEDs, just single color.
