Hi guys,

Well, after a few weeks researching this forum and grabbing some ideas for a project, i've come to build a "plug and play" setup for my TV. This is not yet finished, but it's already working and I'll show it.

So, I wanted a plug and play setup, without much wires and connections. This way, I just have to connect HDMI and 1 Power cable. I'm just missing a power switch for the PSU. The Pi will use the case button for shutdown. I might install a switch, just for cutting power to the LEDs.

List of material:
ITX Case: https://www.aliexpress.com/item/4000672673547.html
LEDs 60/m : https://www.aliexpress.com/item/32336809966.html
PSU 5V 100W 18A: https://wittko.eu/table-pos-se…eile-geschlossen-100-watt
USB Grabber With loop: https://www.aliexpress.com/item/1005001699389687.html
Rpi4 4GB

ITX Case, It's probably the smallest form ITX case I found. For the price tag it was great, included power button to shut down the Pi and 2 USB ports, that will be working once connected to the Pi.

LEDS, tried to find the best price/performance, they are not yet calibrated, but the "default" it's not too bad!

PSU: This was the smallest 5V PSU I found capable of powering the whole led strip ( Hyperion stated12.3A ) the Pi and the Grabber.

USB Grabber: Works great. The loop allows me to not to have a splitter and since I already have a switch (AV system) it's perfect. Worked out of the box with Hyperion.

Here's some pictures.

I'll post later a video of the setup working and will update once I make the last changes.

Thank you.

ok, wasnt a front, just to be sure how long is the cable from the rpi to the leds? should be under 10cm... but the best thing would be, as you mentioned, a level shiffter! (in any case)

Is this a requeirement? Can we make any thing to circumvent this? Maybe using a Arduino and Adalight could be an alternative, since it's connected trough USB. I'm trying to build a standalone solution with plug and play features, so a restriction of 10cm to the led strip is awkward

Some Loop grabber can work yes, but i'm not expert about wich one is supported. dont forget what Alpha7 told: you need some horsepower to handle 4K input with pi. (by the way a pi zero don't even has usb3 and the required bandwith)

Yeah, i know. I'll be using a Rpi4 although my input will not be 4K. It's only 1080p.

Will something like this work? I'm not sure about what chipset controller this uses. I have an AV receiver with HDMI Switch (5 inputs), so I'm expecting to grab the HDMI OUT and split it between the Raspberry Pi and the TV.
