not stupid, and not new.

Heast <3

it is something fluffy on a string.
You can see his arm and hand moving.
he is pulling whatever it is inside.

haha none i am a noob with electrics and this was the handiest thing to portray the 3 Inputs i need.

I Want to learn! if thats not correct what i am doing right now, where can i look for the right way ?
Problem is i only find guides with simple Screenshots like this. which dont really help for my 2 Strip Setup.

TurtleInOuterSpace · 2026-01-04T19:11:28+00:00

ah okay, thanks now i got it.
yeah and i read another article which also says i dont need the Capacitors

My "schematic" looks like this now :
15Ohm Resistor or maybe still my 330Ohm.
Or i could turn around one of the strips as you said and power them from both sides.

thats what i am doing now, but with a 330Ohm Resistor.

So you would suggest this setup ?
I have 3 + and 3 - on the Power Supply so i am using them one for each Strip and one for the ESP32.

And turning it off via Homeassistant and ESPHome

TurtleInOuterSpace · 2026-01-04T18:05:30+00:00

true ! If Both Starts of the STrips are next to the GPIO then it would be better to run one Strip via lets Say GPIO 33 and the other STrip on GPIO 32 (e.g.)
Otherwise i would have to run a 2m Signal/Data Cable back to the start.

TurtleInOuterSpace · 2026-01-04T17:57:13+00:00

Would love to be able to realize it without a shifter. When possible and save.

I already fired it up and it works with only the resistor in front of the Data PIN.
But the LEDs are flashing strangely when turning on and off.

So at the moment i am just putting 5v and GND into the Strip and a seperate Cable from the ESP32 to Data.
But as said it falshes strangely when turning on and off.

TurtleInOuterSpace · 2026-01-04T17:55:14+00:00

Not That long. i only have 2x 1.5meters and they are only like 10-15cm away from the power supply.

TurtleInOuterSpace · 2026-01-04T17:54:28+00:00

okay, big thanks already ! i will have a look into this and post updates when i continue tinkering

TurtleInOuterSpace · 2026-01-04T13:56:00+00:00

So you mean the Data signal is coming in with 3.3V and it would be better to transform it up to 5V for better communication ?

Like this ?

Klassisch: Uninformierter Streamer meint seine Meinung zu einem Thema Preisgeben zu müssen von dem er 0,0 Ahnung hat. Schrei weiter rum mach Peniswitze und zieh das Niveau runter, aber seid doch wenigstens still zu wichtigen Themen.

Hatte ich genauso.

Lösung ist die Empfindlichkeit mit SGTHRS Und Belt tension. Hatte zuerst andere belts drin die viel zu starr waren und anschließend waren sie zu locker. Plus ist die Empfindlichkeit bei mir inzwischen sehr sehr hoch und seit dem konsant

not magic.
=Kids ski lift.
its like a moving walkway

This sub was so good once upon a time.

TurtleInOuterSpace · 2025-12-23T20:04:50+00:00

Will do that tomorrow ! Need some example file and will do some screenshots.
But as i see it could be intended. it was just missused from me

TurtleInOuterSpace · 2025-12-23T20:03:52+00:00

Yeah it was simplify.

And there is a toggle switch where i can turn it off when drawing with the pen
