    Default Pixel Delay (a.k.a. Pixel Data Splitter)

    After many months, I finally have time and energy to finish this project.

    I have 3 new boards I call Pixel Delay (a.k.a. Pixel Data Splitter.)
    1 channel board - which in size is similar to my buffer/driver board, and is designed to be used with T-splitter, weather sealed between 2 cables.
    3 channel board - slightly bigger, but can also be weather sealed.
    6 channel board - a bit larger, must be installed in a case.
    (note that 1, 3, 6 is the number of "delayed" channels, so the total number of branches is 2, 4, 7.)
    All outputs are buffered (so you basically have buffer/line driver,) and the 3 and 6 channel versions have a buffered output of the input signal.
    1 and 3 channel boards can be sealed, but they can still be programmed. You use magnet to put the board in programming mode. 6 channel version has a mechanical switch.
    1 channel board can be programmed by sending exact number of pixels to be delayed, 3 and 6 channel boards have to be programmed using either Terminal (PC) or a small programmer which I will make. Pictured boards are prototypes, final boards will be slightly different.

    Any feedback is appreciated.

    Can the “delay” on each channel be set discretely?

    Yes, they are separate channels

    I am sorry my ignorance, but where would I use this board?

    A simplest use case: you have a data cable running to the front of your house and you have flood lights or pixels on the left and the right side. If you simply do a T split, you will not be able to control both sides individually. To do that you would have to have a return cable from the end of one side, which could be many ft away. The delay or splitter, will split the data, so that 10 first pixels are sent to one side, the rest to the other. That way, you can control all pixels individually.
    Multichannel delay can be used for example for the star or the top of the tree, eliminating the need for a return cables.

    I love the the tree with spheres in it in this video. If I’m understanding this correctly, these would make wiring simpler by allowing you to make “branches” out to each prop rather than chaining them together or using lots of ports. Is that correct?

    Can you split 12v pixels as well as 5v? I see an input for 5v only.
