Hi all - ive lurked for a few years and exhausted my bunnings/powerboard setup and this year I am getting serious (albeit a but late to the game with only 4 weeks to setup!)
Its very late to be staring a pixel display now.
Suppliers in China will be at peak with last minute orders.
I'd suggest to keep looking into pixel displays, there is quite a bit! 4 weeks to learn how the controllers and software works is a stretch.
You could start by getting a string of pixels and using a basic controller to cycle through colours, then add music synchronization later.
Start in baby steps, no ones display happens overnight.
