as for a picture, here you go. the waldorf kb37 features uses the same fatar 37 key w aftertouch. not sure if/how much the waldorf one is weighted, as fatar does different amounts of semi-weigthed on demand. also read some (unconfirmed) rumours the moog subsequent also uses a tp9/s. http://www.fatar...

Ok guys, was away for a bit on family duties, here’s the final update before I put in the order within the next 2 days! - I had @FantomXR change the LED Ring design to 32 instead of the prototypes 36 LEDs. That’s what I originally had planned too, for three reasons: 1. easier mathematical mapping of...

was busy with family stuff for the week so unfortunately no updates. i will 99% likely change the design to 32 LEDs per ring for easier adressing, rhythmic use and to have a little more space between the LEDs for masking. putting in the order tomorrow, i will order a small number of extras but anybo...

yes i strongly consider doing that once the project is finalized and the order arrived & everything is working. will need some extra time for documentation etc.

Frontplate design w LED light channels, help needed

hey guys, i'm shamelessly crossposting my post from the midibox forum cause i am sure there are a ton of frontplate/material experts around here... i am building a desktop keyboard synth with these nice rgb led ring encoders, in a tiny form factor: https://www.muffwiggler.com/forum/userpix2/51429_im...

these were the quotes from the original prototype order, i expect another 10 ish percent off with the discount. didn't do the maths or get an updated offer yet though... Encoder board: 50pc --> 10€ / pc. 100pc --> 7€ / pc. 200pc --> 6€ / pc. LED-Ring board 50pc => 28€ / pc. 100pc => 23€ / pc. 200pc....

aaaaand here's a video with some basic music encoder functions. also included the requested one-dot-mode.

as i said before, colors look 1000x better in real life.

Did you write your own library or use the predefined Adafruit library for the WS2812? for testing i am currently using the adafruit neopixel library. i want to switch to FastLED soon though since the performance seems to be a good bit better. and since it looks like for my main personal project i w...

You can of course adress the WS2812 series in a way that you only display one dot per ring, and yes, that would save a lot of power! i personally prefer a full line up to the value dot, for aesthetics but also because eg. a single dot can get lost/be hidden behind the encoder knob. an alternative/co...

Looking nice. Thanks :miley: - what is the final refresh of the LEDs? Depends on the amount of LEDs per serial line. If you want to maintain 60Hz refresh rate, the ws2812 protocol limits you to 500pcs, about 1000 at a 30Hz rate. so that's 13-14 LED Rings at 60Hz, double that at 30Hz. And if you use...

RGB LED Rings w 36x WS2812 2020 and Rotary Encoders

Hey guys, i designed these PCB boards with the help of an engineer, 4x1 LED Rings and Rotary Encoders for music controllers. We managed to squeeze 36 WS2812 RGB LEDs in 2020 size in a 33mm diameter ring. Prototypes are running super smooth under arduino, also confirmed working on midibox and axoloti...
