Neither can I ... and I've about had it watching him crush anyone's throat that attempts to make anything similar to ColorDMD yet he announces his RGB LED version to great fanfare w/o any regard to other projects going on. It isn't my intent to trash that product, but having seen some of the legal threats over bloody pinball machine displays, I can't contain myself anymore!
I have all of the respect in the world for them from a business perspective as they've had great success with a rather innovative product, but these threats of suing people just to get them to stop producing products that look even remotely similar to ColorDMD has me at wits end. A goddamn display shouldn't cost north of $400. I understand that there is a rather significant time investment when it comes to colorizing frames of data, but additional sales of ColorDMD hardware should cover those costs. Unless the displays are more than I think, there isn't much more than $80 or $90 worth of hardware in that system. I'm not a damn communist, but that's one hell of a markup and is ripe for competition. However, throwing around legal threats that are not related to the architecture of his product, especially when none of his patent is being violated, grinds my gears in ways you cannot imagine . A hobbiest will simply quit working on something similar to ColorDMD due to the potential legal headaches!!! Is anybody aware of him threatening someone from making an LCD that simply adds a single color to the DMD source data? That wouldn't be patent-able nor is his HQnX scaling algorithm he uses for that 'sigma' feature.
Also, can someone explain to me (or point me to) what his patent in particular covers before I go on another rant and make myself look like an ass? From what I have read, it seems like he is patenting his mechanism for identifying a particular monochrome frame with the intent of adding additional color information. Is this right? Is he patenting the identification of a full frame of video with the intention of integrating chromatic data with a luminance value and pixel position in the frame? For example, is he simply computing a CRC value for a frame and performing a kind of hash lookup to determine the frame being displayed? Does it specifically say "Full frame" in the patent?
Getting back on topic, I finally got my Teensy based RGB DMD powered up and running on my desk & it's framed in one of those FAST pinball mounting brackets . The Chinese company gave me a refund for the two damaged displays and let me keep them. I can repair one with the LEDs that were scattered in the shipping envelope ... the other is still nasty ... I'll just use this set for my "development" setup. Next step is to install the SW dev. environment and de-rust my SW skills (I design FPGAs for a living ... basically the same thing that drives ColorDMD ... they'd be useless for RGB DMD ... but developing those over the past two decades has rusted my SW skills ).
