Aaaaand... I got it working with Modul8 (my visuals software of choice). Proof of concept at least.

Thanks for that heroic
I am confused
5 metres divided by 50 pixels = 100 mm. 5 metres divided by 30 mm = 167 pixels. Unless I'm missing something, the 50 pixels and 30 mm dot pitch on a 5 metre strip don't add up.
I've just had a look at the GL-CB-RGB (if that's what you're using). It seems they have 150 pixels, at 33mm dot pitch which I calculate to be 4917 mm from first to last pixel, with some space on either side, making up the 5 metres. Assuming this is correct, a 10 x 15 pixel matrix could be built from one.
Is that correct?
8 channels x 150 pixels = 1200 addressable pixels via your driver, which could be a 30 x 40 matrix. We would need 256 of these drivers for a 640 x 480 display, which seems a bit high. It would be ideal to have a version that could address at least 307200 pixels required for VGA and at the bus speed required to deliver a decent frame rate.
Do you think this would be technically feasible?
I am very keen to develop something like that. I'm a software designer by day, and I'd like to have a go at this.
Awesome, thanks for the link. Which of their flexible strip products are you working with?
Each pixel consists of three LED packages. Each package contains an RGB LED. There are 50 pixels, and 150 LED packages.
The LED packages are "dots" but each pixel contains three dots.
I'm not sure how else to say this that will make it any clearer.
This driver card should work with all their "intelligent" LED strips.
This is not practical.8 channels x 150 pixels = 1200 addressable pixels via your driver, which could be a 30 x 40 matrix. We would need 256 of these drivers for a 640 x 480 display, which seems a bit high. It would be ideal to have a version that could address at least 307200 pixels required for VGA and at the bus speed required to deliver a decent frame rate.
That's OK, I think it's clear now. My interpretation of that is that each addressable unit consists of 3 RGB points, at 33mm, that would make a dot pitch of 99 mm given that the three points could not have different RGB values.
It doesn't sound like these would be practical for video. Though they'd still be good for other effects.
I'm looking for the least expensive way to create something like this...

Interesting... so if you wanted to create a 50x50 pixel LED matrix with square pixels then you would need 150 strips. That might get expensive.
Maybe these strips would well suited for scrolling messages. If you ran 24 strips horizontally with, you would have a 50x8 pixel scrolling message board that was 5 meters long. Cool!
I have a piece of the hl1606 strip, and while the pixels are individually addressable, you cannot individually control the brightness of the chips. I played with some hacks to use the fade line to adjust it, but there really is no good way to do anything better than 7 color mode (or a 15 color mode with a bit of trickery with the strobe line). I was planning to build a simple DMX-hl1606 protocol converter, but it wasn't worth it to me running in 7 color mode. I am interested in getting some of the 24 bit ones, which company did you order your from?
I too bought my hl1606 strait from China, the seller 'forgot' to ship it for about a month but after some bitching and moaning it finally came. That said, if anyone wants to play with some of the HL1606 type strips send me a PM, I am considering putting my strip up on ebay since it is not usable for my application.
Hi Heroic,
Are you using the GL-CB-RGB strip?
I would be interested in a controller board if you decide to do a group buy on them.
Thanks!
