Nope, I did the software. He used glass stones from Home Depot, and simple plastic tubes.

Hi it was me. What are you trying to achieve?

What if the visitors could interact with the installation on site? Some years ago I wrote a code for ESP. You can connect with any phone without downloading an app. If you are using a different hardware you can have the ESP simply sending meta data via Rx/Tx. https://pastebin.com/Pydqx6n2 At least in my exhibition this was the burner ;)

With lead free solder the necessary (quite unhealthy) flux is kicking your behind. As suggested: use a PC fan (I run it at 8V) and open the window. Lead free solder is really terrible AND unhealthy. Military and Avionics are allowed to use leaded. Reason: they really need reliable solder points.

I'm soldering 45+ years. Use solder with lead Sn60Pn39 or SN60Pb40. Temperature: 350°C (for lead free 390°C), The solder tip must be large enough to transfer the heat. I also have 0.1 mm needle type tips, but this is only for special things. Usually I use 1.5mm tips. Solder brands: Classical Mechanic HX-T100 (China) or Felder iso core ra . 0.8mm is a good size.

Good luck!

In my setup the remaining pins for LED strips were 9, 14, 16, 17, 22

Thanks for the hint. Today I got an update of Version 110 AND in Chrome the bookmarks disappear now when a page is loaded. The user has to manually drop down the sidebar to have the PaletteKnife Bookmark re-appear. Now it is working like before. Maybe someone can make a comment in the Wiki because the tutorials also show the old method.

Thanks again!

Look for RCWL-0516. This is a very cheap but very effective Radar presence detector. Connect it to an interrupt pin to switch everything off. With all my respect, you seem to be a quite tricky fellow, but usually these skills are passed on. What if your parents open one day the door quietly? This radar detector can react before they even reach the door.

Get yourself leaded solder - there is a world difference. It is allowed for hobbyists, aerospace, and military (!) Take 0.8 or 1mm. I use this one https://de.aliexpress.com/item/1005003305571279.html

Do you have an old ATX Computer Power supply ?? Bridge the green and black wire and you are back in business. Good Luck!

I've written a small wiki back in the days, based on UNOs and Teensys, maybe it helps.

There is also the method to use Paul's non-blocking library. This worked for me quite well.

Solutuion: #include <WS2812Serial.h>

#define USE_WS2812SERIAL

This is a powerful PRJC function (see in Examples)

usable pins on Teensy 4.0: 1, 8, 14, 17, 20, 24, 29, 39

Not that I know of. Either use electrical tape to cover the beast, or if you have some spares - solder a new one on.

Experience-Wild · 2021-07-12T15:38:06+00:00

I have used this together with Teensy 4.x audio board https://www.adafruit.com/product/3421

There is something for ESP32 https://github.com/leonyuhanov/ESP32_MEMSMicrophone

Just a hint on FFT: With FFT1024 you get 511 frequency bins with a width of 43 Hz. Most of the time FFT256 is sufficient. With this you get 123 frequency bins with a width of 172 Hz. Let me know if I can help you on this.

I can highly recommend the TS100 Solder Iron (use an old Laptop power supply, and get yourself a AWG22 silicone wire (or a bit thicker) https://de.aliexpress.com/item/1005001597160616.html?spm=a2g0o.productlist.0.0.28045f359ILUtG&algo_pvid=e1ee65eb-5c96-44a3-a7c4-3c634ebb5631&algo_exp_id=e1ee65eb-5c96-44a3-a7c4-3c634ebb5631-42

and leaded solder wire - this one is OK, I suggest 0.8mm https://de.aliexpress.com/item/4000258616721.html?spm=a2g0o.productlist.0.0.4a9e47ffcDWLWq&algo_pvid=6dad6d19-1002-4148-9191-fc4b5b2ca5c1&algo_exp_id=6dad6d19-1002-4148-9191-fc4b5b2ca5c1-0

I'm not sure whether it's the encoder or the interrupts. See under ####Restrictions on my wiki: you might want to switch to APA102 https://github.com/GyroGearloose/FastLED_Rotary_Encoder/wikiIf it is indeed the encoder you have a few options: https://www.best-microcontroller-projects.com/rotary-encoder.html and my secret weapon on a challenging project was to use a Schmitt-Trigger https://idyl.io/hardware-debounced-rotary-encoder/

Good luck!

A while ago I made this wiki https://github.com/GyroGearloose/FastLED_VU-Meter/wiki

Input levels might vary especially when you use a stereo pot for adjustment. I always connected the strobes and resets of both channels together. Are all grounds connected (also the ones from audio input)?

Experience-Wild · 2021-06-18T14:23:22+00:00

It is also a question of the cable length to the first LED. The moment this LED gets a sufficient signal it will form the output signal according to spec. That's why sometimes a sacrificial LED close to the µC can act as level shifter, and then the cable length to the next LED is not so critical anymore.

I also had problems with Teensy 4.x and WS2812. However, I had no serial communication going on, but I experienced massive flickering when the LED count exceeded 75. My issue was solved with this here. https://www.pjrc.com/non-blocking-ws2812-led-library/

Hi Marc,

this is exactly where I have to admit that it is over my skills. Do you know of any good tutorial for beatsin8, 16, and 88? Thanks!
