This is my second stab at bias lighting. The first time was on the back of my ancient Panasonic 42" plasma (110% would buy a plasma again --- RIP, Plasma Bros!)
Days of console gaming are behind me (I've returned to PC gaming for now), so I'm going with a decent mid-range QLED setup and the TCL and/or Hisense seem to be legit options. I HAVE NOT PURCHASED THE TV YET (probably this week, but I've been saying that for a couple months ).
I am going with an 'engineered' solution. I have designed 3D printed brackets to mate with my VESA mount. This will hold the LEDs at 30 degrees, 25mm (American metric lovers, unite!) offset from the edge of the TV and ~25mm from the wall. The LEDs will sit in aluminum channel.
Brackets and Frame
1) 3D Brackets: I'm probably final now but want to fully mount before sharing
2) Configuration Spreadsheet: This will be shared once fully installed. This lets you figure out your cut lengths.
3) Aluminum Track: Muzata Transparent Diffuser Extrusion U1BT
4) 3D Filament: HATCHBOX 3D Filament Dimensional Accuracy
Bracket design interations, finals in red. Brackets have track guide that holds channel in place. Glue not necessary. I will likely glue.
Frame mounted to wall, crooked because the VESA mount has 'play', will be level when fixed to a TV.
Example of my spreadsheet. Yellow are variables. Green is cuts. It'll make more sense when I clean it up.
LEDs and Other Hardware
1) LEDS: BTF LIGHTING Individually Addressable Non Waterproof Separately <- Some people have issues with these lights. I have found them STELLAR to work with. The CLK signal is king.
2) RPi: Raspberry Pi3B+ & Hyperbian
3) Power Supply: Will provide model once wired
4) Frame Grabber: I have a 1080p but may update to 4K to enable HDR if it bothers me. Will know this week (if I buy the TV finally )
5) Video Streamer: Amazon Firestick <- This is my personal preference and connects directly to the Frame Grabber.
6) Project Box: I'm likely to design and print my own so I can have bulkheads and streamline plug-n-play. This will be done next week, I have most components and will share once built. This will happen after I make sure everything else works. It's 'dressing' for the end of the project'.
7) Wiring Diagram: I'll provide a rough (or detailed) wiring diagram once all other bullet points are done.
I will update this post with videos and further images as I assemble this week.
