Do i still need a Pi if i use an Intel NUC for Libreelec

itsmechrissyd · April 11, 2023 at 12:26 PM

Hey all,

Super excited to get this set up. I've got a rooted LG C9 that i've installed hyperion and PiCap on. I'm wondering though given i run LIbreelec on an Intel NUC whether i could get away without having to get a pi/capture card? Essentially i'm still at the stage of just working out what minimal equipment i can use to get this running. Looks awesome.

PicCap (Grabber) and Hyperion run on the LG, you need a controller to which the LEDs are connected, e.g. ESP32 with WLED software. A power supply for the LED and mostly a level shifter.

If i bought and LED strip with WLED already installed that could be my complete set up ?

Here are my lights https://www.amazon.co.uk/gp/product/B097TH15VZ?tag=hyperioforum-21&ie=UTF8&th=1

Just done a little googling and think i could have a completely no solder solution here if i found a WLED setup taking USB light input and having USB power

I've got a current LED strip of static colours that i power using one of the USB ports on the LG so would be hoping to use the same here.

USB doesn't deliver enough amps, you need a power supply for the LEDs!

No more than 750mA should be operated via an ESP.

On the LG you have max. USB2.0 with 500mA or USB3.0 900mA

Just looking at the 2m lights i've got now they're powered by USB?

If not i'll start googling some compatible light strips to give a test

For the set from your link you don't need a rooted LG, PicCap and Hyperion. But you won't get a good Ambilight with it either.

Yep i also don't get great coverage for my full 55' so i've gone and purchased BTF LIGHTING Individually Addressable Flexible Non Waterproof

For the controller i do have some old Arduino nanos kicking about https://www.amazon.co.uk/gp/product/B072BMYZ18?tag=hyperioforum-21&ie=UTF8&psc=1 i'm not sure though if these are compatible?

Arduino vs ESP8266 vs ESP32

https://diyi0t.com/technical-data…ler-comparison/

Which ESP is the right choice, what are the differences.

Welcher ESP ist die richtige Wahl, wo liegen die Unterschiede.

ESP32 mit Ethernet für geringste Latenz.

ESP32 with Ethernet for lowest latency.

≤ 5ms Wlan, ≤ 0,5 Ethernet

[…]

However, it should be noted that a maximum of 490 LEDs can be addressed with both of them via UDP (Hyperion, EnigmaLight).

With more than 490 LEDs you have to use another protocol (tpm2net or DMX E1.31) or split it between…

Ok slowly and surely getting there. Think this would do the trick for an ESP32 board? Wt32-eth01 Embedded Serial Port Networking Bluetooth-compatible Ethernet Wifi Combo Gateway Mcu Esp32 Wireless Module Wt32 Eth01 - Integrated Circuits - AliExpress

Once i've got my light strip and this i'm going to need a way to power the ESP32? Is that direct or do i connect it to an arduino ?

Lastly, how does hyperion picap actually connect to this ESP32 board, is it just over a network? I thought there'd be a direct connection

Again thanks for all the help so far!

If you go with ESP32 or ESP8266 you are going to run WLED as "translator" on the ESP. No need for arduino anymore. The ESP gets powered by the same power supply as the LEDs

I assume you like to run LE11?

If yes, then you will need Hyperion (Server) running in a Docker container within LE11.

You have to configure the WLED instance in the hyperion.ng server. After this is setup you have to configure the IP of the Hyperion server in Picap. If all is done right, you are enlighted

My setup is based on Wemos D1 Mini over WiFi. Hyperion Server runs on a Proxmox container.

With WiFi based boards you will introduce some more latency as you can imagine. For me it works however...

Awesome yep i do run LE11 - However i've actually rooted my webos tv so i was thinking i connect my esp to that instead.

I'll checkout your board and pray i get the same results over wifi.
