that is the color changing LED Strip, and need a LED RGB controller ,which is used to perform a wide array of creative lighting options for any situation. Whether blue, red or green light, this multi-color strip light will deliver consistent, fantastic results. this type of led strip usually run dc12v, 5V type is rare, I haven’t seen by now. one reel (16.4ft) of this kinds of led strip is about 128 dollars(http://www.bestlightingbuy.com/smd-5050-color-changing-brighter-led-strip-300-leds-16-4ft-reel.html), if 160 dollars, it is a little expensive.

Yes, it’s mounted into sheet steel staples and there is also diffuser over the strips to make the light a bit more smooth…

@marshall

it is 160 dollars for 5m, so still about the same price.

@mystery

nice vid. did you mount it yourself?

Not really rare to come by. check this out. top two led strips are the ones I am talking about. http://www.superbrightleds.com/cgi-bin/store/index.cgi?action=DispPage&Page2Disp=%2Flight_bars-rgb.html%23rgbdc83 they are really pricey though. 16.45ft will cost you 120 dollors. OUCH.

If you are interested in these strips.

I supply them.

I also have standard controllers, these have 84 programs and speed adjustment.

If you are interested, mail me at nando(at)LNSound(dot)nl

price of the strip is 25 euro’s per meter, 40 leds/m

From what I can tell the HL1606 based strips are kinda janky because they don’t take a simple instruction such as “this pixel, be this exact color”. Any schemes that try to do that with this type strip have to hack the built-in fade feature of the chip and stop the fade at the desired color wanted. So I imagine in bigger scale applications you’d run into lag/latency issues as it takes that much more time to just get the pixel to be the desired color.

The LPD6803 seems to be a more capable chip, and there is a new revision of it, the LPD1101. All this stuff is hard to get info on as it seems limited within the scope of Chinese industry, i.e. Chinese datasheets and websites.

This type of RGB LED strip light seems common on http://www.ledease.com/optoelectronic-component/flexible-led-strips/.

This american company seems to sell LED strips based on the LPD-6803, and is gonna have a DMX driver for it. Sounds pretty sweet.

There’s no way to access the PWM of the LEDs per se. I have made a slightly better Arduino library for them here:

Thank-you so much for all the information!
I’m wondering if someone has tried bypassing the custom chip commands and outputting directly to the pwm.
I would be really grateful for information about what exactly is required from say the Arduino end to drive your own colour signal.
Also the information about the latency involved in passing such a signal through the strip would be greatly appreciated!

I’ve done a writeup on how the HL1606 works that may be useful to anyone trying to drive this chip, the datasheet is not entirely accurate. See http://bleaklow.com/2010/05/24/how_the_hl1606_works.html

bit banging, or…

… is an arduino mini pro fast enough to bit bang the same number of shades i wonder

There are other IC varieties of pixel RGB leds which have 32 controllable shades per channel which I am currently looking for programming information on.

In particular LPD-6803 based “pixel rgb led” modules and controllers appear common when searching the web. These are suitable for video and perhaps better for the POV strip application I have in mind. The only sources of information on the web I have found on this chip so far are:

http://www.mikrocontroller.net/attachment/59878/LPD6803.pdf (in Chinese)

and some documents I have not yet registered to see on pudn.com

This would be my ideal platform to program for on Arduino, so any comments or advice on how plausible this chip looks to control would be gladly appreciated!
