I have a dream! I would like to use SK6812 mini LED strips in a candelabra project. I’ve made a similar candelabra before but I think an addressable form is necessary to push humanity into its next era :stuck_out_tongue:

I want to run strips down six sides of a steel hexagonal rod in three candelabra sticks. The strips will be about 47 LEDs long so a total of 846 LEDs

I was advised to use a Teensy 3.2 for this. Does anyone else think a different controller would be more suitable or alternatively, that Teensy 3.2 is the way to go? Thanks.

The following links/images help explain my intentions pretty quickly, I think:

Yes, kind of like that but with smaller tubes and fewer strips in each tube (I’m guessing that has more six strips in it).

Someone with better maths will come along soon…

Usual duinos allow you to update all 847 leds at once, but it takes time.

The teensy has a parallel option where you have 8 strips of 100, and the strips update 8 times as fast.

I believe that regular duino visually slows down with the updating but teensy is quick enough for video etc.

…you need a good powersupply for that :wink:
Remember: you need 20mA per color per LED… so 60mA x 486 LED …nice…

Mine has 14 Stripes

@Solo_Han_Solominator I realise that but thanks for the heads up! I figure that programming can ensure it never exceeds the capability of the power supply so it won’t necessarily need to provide 52 A.

+Jean - Paul Kluck What do you use to control it? Did you make a project log online perchance?

@Kelvin_Mead Thanks Kelvin, I guess I’ll be using the Teensy.

Cool project @Sean_Smith1 . Your first non-addressable one has a great look.
You can’t go wrong with the Teensy 3.2

Thats what I building up to, the programming looks great.

Teensy 3.2 is what I’d go for.

But this might save your power budget: the theoretical viewing angle of 5050 LEDs is 120º, so you only need three strips (on the sides of a triangular prism, rather than an octagonal one) to get 360º coverage. That gets you down under 20A which is much more manageable.

(Note I fully support over-engineering the crap out of LED projects, if you want to build a > 50A retina-scorching monster don’t let me stop you :slight_smile:
