V-Sink, takes the pain of driving many thousands of channels away, by appearing like a display to the OS and taking care of the rest. The current implementation can drive 32768 RGB LED pixels at 30Hz.
I am currently working on a DMX driver. V-Sink should be able to drive 192 DMX universes (if you can fit that many transceivers on a board) from an HDMI port. A massive light show can be generated or played back by set-top box or a raspberry pi.
Took me forever I know but I was hoping to find the time to clean up the code and make it Open-Source compatible. My time organisation skills failed me.
Here's the raw and dirty code for anyone interested to have a look. I am happy to help if someone wants to give it a go or contribute.
Unfortunately, the HDMI connector on the (otherwise amazing) pipistrello board (http://saanlima.com/store/index.php?route=product/product&product_id=51) cannot be used as an input.
The HDMI clock pins must be connected to global CLK pins for HDMI input to work and they are not. This basically means that Pipistrello can't be used for HDMI input unless you are willing to do some board rework. The HDMI SDA and SCL signals from the connector go to GCLK pins. By removing the I2C level translator chip you can run two wires from the HDMI connector to the I2C chip pads. This way the HDMI clock pins can be routed to GCLK pins without any trace cutting.
This is a fairly delicate rework and needs steady hands, but I've done it successfully to both my pipistrellos. You then need to reroute the SDA and SCL signals to a generic I/O, which is fairly straight forward. In the photograph you can see how the hack looks like, but I could write/record a guide if people are interesting in modding their boards.
I'm working on the software and hardware in parallel (focusing more on hardware right now - designing cheap fpga boards), whenever I can find the time (v-sink is a t-sink too). Next comes VIDEO 2 DMX - hopefully very soon. I will also try to upload videos/demos as soon as possible.
EDID is implemented as a software EEPROM on the FPGA and holds an edid dump from my my monitor. Yes, V-Sink appear as a Dell monitor when you plug it into a pc. I need to edit the ROM to look more professional...

Great Idea! but this is really interesting https://inshotproapps.com/inshot-for-pc/
