Hi! I want to build a see thru RGB LED video wall. You may have seen something simular to what I want to build in Apple's retail Christmas display, and I believe currently for their Macintosh 30th Anniversary displays. I want to drive it with the driver boards in the Adafruit shop located here: https://www.adafruit.com/products/1453, but the problem lies in the matrices, I cannot find - ANYWHERE - see thru RGB matrices. It is for this reason that I decided to individually solder each and every LED my self (I like to spread out and make my projects last ). My problem is that I don't know what chipset of led controller IC to use and what the pinout is. I hope you can help me. I don't think that I'm doing something stupid, but I am probably biting off more than I can swallow.
Let me give you some more specs I want to use:
Raspberry Pi to send video
9ft by 9ft.
370x180 pixels for 2.77 ppi
Thanks!

Smaller outdoor Re: Building a Large RGB Video Wall
Would you please help me build a small 13 inch by 66 inch outdoor LED. This is for a tiny struggling Mom and Pop Shop so cost is key. My labor for this project to them is free.jusbour wrote:Hi!

Re: Building a Large RGB Video Wall
I had to search through google to find a photo of this....never seen it before.
I'm sure they were custom made with nice thin tubes/supports, but It almost looks just like a bunch of these, inside tubes, strung up like venetian blinds. You can see in the first photo that the 'data line' snakes through the 'blinds' (yellow). And the supports (green) could be purely mechanical....or extra power/ground lines.
That's probably how I'd replicate it, too. Get some plastic shower rod covers (or wire-wrap cord-hider thingies), drill holes in them, poke the "bulb" part of the pixels through, and tie them together. And, run them all with an Arduino, Teensy, or these new boards -

Good luck!
