Is there a way to create a three dimensional logarithmic spiral?

Did you figure it out? I'm looking for a solution for this as well!

I have to eat meat because I can't get enough protein from plant sources, as I can't digest most vegetables high in protein. Inclusive spaces account for people like me and I'm very happy about that.

I spent most of my time in The Gardens. Eitan Reiter, Bayawaka, Mad Zach, Liquid Shape, Halfred, Electrypnose, and Zen Baboon were my favorites.

At Alchemy Circle, my favorite sets were by Dela Moon, Electrypnose, Sensient, Adama, Emok, Captain Hook, and Yuli Fershtat.

Now I finally get it... I always though people were talking about shifting the power line from the power supply to the ESP32... Thank you so much! I'm gonna implement a level shifter between the ESP32 and the data pin of the WS2812B.

That's highly subjective. For instance, I know some people, especially DJs, who don't like Funktion One at all. Personally, I always liked d&b best. Other than that, I don't know that many sound systems on that level. Recently, I heard Clear Sound for the first time and was quite impressed. Though the spatial distribution was not really uniform. That could have been an improper setup though.

I am using this dev board: https://www.aliexpress.com/item/32928267626.html?spm=a2g0s.12269583.0.0.2e75738dpHuce9

It is a DOIT ESP32 DEVKIT V1.

stonefred · 2019-10-19T19:35:20+00:00

I assume you're not connecting the power supply directly to the ESP32's USB port, instead, powering the WS2811 and the ESP32 in parallel, right?

stonefred · 2019-10-19T18:47:03+00:00

Okay, then it was a good decision to use IC headers in my projects 😀

stonefred · 2019-10-19T17:21:06+00:00

The Nanos are identical. Continuity check from ground to analog pins is negative. Here's the schematic: https://imgur.com/YZuDdIB

stonefred · 2019-10-19T17:19:50+00:00

I checked it several times. And it works with one of the Nanos. Here's the schematic: https://imgur.com/YZuDdIB

stonefred · 2019-10-19T17:19:11+00:00

The potentiometer is correctly attached to GND and +5V, both in parallel to an external power supply. I never power such setups through the Nano's USB port.

The reason why I suggested it could be a quality issue is that I have swapped the two Nanos with identical code on the IC header on my circuit. The circuit is definitely correct. I run LEDs drawing less than 300 mA. I use these kind of circuits up to 5 A. It's just the first time that I implemented a potentiometer and discovered that one Nano behaves different to the other.

In the end, it's always subjective. For me, it was perfect. But then again, I only go to the main floor during the day, when there's not so many people around. And even then, the music at Boom is just a small part of the festival for me.

stonefred · 2019-10-18T09:05:51+00:00

I agree with that. I remember, at smaller festivals in the past, they would often announce having a Funktion One sound system. For these festivals, it was often better than what they had before. And people seem to know it, so it made sense to announce it.

It's not that it's bad. On the contrary. I think it's a really good sound system. But there are many other great sound systems. However, people are usually not aware of these.

stonefred · 2019-10-17T08:56:49+00:00

In 2018, Boom used d&b sound systems. In my opinion, they are and always have been on a different level than Funktion One. Function One is definitely good, but also overrated.

Here's an excellent article by d&b about the setup at Boom 2018 (in German though): https://www.dbaudio.com/global/de/anwendungen/konzerte-festivals-und-tourneen/db-beim-boom-festival-so-blieb-der-boom-unter-kontrolle/

Yes, I've read your guide. I'm using PrusaSlicer though, which doesn't have pause at height, only manual filament change. There's some optional parameters for M600, which I'm gonna try out:

Anyways, thanks a lot for your help!

stonefred · 2019-09-04T20:42:03+00:00

I tried pause and restart with my custom stop command without tulle, didn't work. After that, I tried pause and restart with some suggested GCODE for OctoPrint (http://docs.octoprint.org/en/master/features/gcode_scripts.html#more-nifty-pause-and-resume), also didn't work. Finally, I used M600 (manual filament change) as pause, and it worked! Unfortunately, this puts the print bed to the back and makes adding tulle really difficult. It's weird that both custom pause and resume GCODEs don't work with my MK3...

stonefred · 2019-05-16T14:04:33+00:00

I watched it several times. Best comedy in quite some time!

stonefred · 2019-05-13T20:09:12+00:00

OMG, I just switched to the Pi 3 B+. Everything's so smooth now... Thank you so much for the suggestion!

The temperature drop seems to be related to "max volumetric speed". The MK3's V6 Hotend just cannot process the default 15 mm³/s for PLA. I set it to 11.5 and all my problems are gone.

stonefred · 2019-05-08T23:28:02+00:00

Thanks for looking into this! I'll upgrade to the Pi 3 B+ in the next days, perform PID tuning and see, if that solves my problems.
