1829 flex strips from ray

[smeighan]

yeah i know, i was including a link to the TM1829 chip set. i plan on getting flex strips, but the flex strip link didnt sho wthe electronics as well as the link t pixels. I assume the exlectronics is the same?

[chrisatpsu]

the TM1804 chip is a 400/800MHz chip (in our situation needs to run at 800MHz

the TM1829 chip is a 800/1600MHz chip (unknown what effects 1600MHz would have)

both chips only have 3 PWM outputs, for R,G, and B.

1804 - 3 channels
1809 - 9 channels
1812 - 12 channels
1829 - 3 channels

Chris, when it says 400/800 or 800/1600, is that a "range" of frequencies or the "two frequencies" they will run?

Since you say the SSCs are running at 800, they "should" work with the TM1829. 

Anyone actually tried? 

[chrisatpsu]

there is a pin on the chip that you either connect to something, or you don't on the 1804 chip.
when it's connected, it's 400MHz, when it's not connected, it's 800MHz

for our stuff, it's not connected.

I've only quickly glanced at the stuff on the 1829 IC.
if it's set for 800MHz, then in theory it has a better chance of being compatible that if it was set for 1.6GHz

This is that grey area of be carefull what you buy from Ray when you go outside what's in the wiki. If someone new comes across a thread like this (and not knowing about the wiki) and thinking those are the lights to buy, then they put all their money into it with a possibility of it not working.

I don't know for certain, until it's connected to my stuff.

If someone recommends stuff that it works with their hardware. It doesn't make it a lock -in that it will work my stuff.

The best advice I can give is that if you think this is what you want. order a small sample, then test it before placing a bigger order.

While I know this is an expensive hobby and the temptation to save money is real and very understandable -- my own experience has been that staying with the KISS principle and not getting into new or untested technologies ... either in terms of hardware or lights ... can really save a lot of headaches down the road.  I know that others are braver (and smarter) than me and have no problem dealing with the issues that might show up ... but my advise to most people reading this is to stay with the WIKI approved lights and hardware whenever possible, because being on the bleeding edge because your trying to save some money ... can often be a bad investment when you add it all up at the end.  Just my $.02 worth, nothing more.    Sean, btw, thanks for talking about this ... as 50% savings IS rather temping, to be sure.

Another point, with the grouping in the new ssc, you can easily program groups of 3 LEDs when you want them that way. With the 1829 strips, you will never be able to address each node or do sets of 4... You better be saving a lot, because you really are sacrificing capability...

I wish he made a 15 led/m flex strip.

From Ray WU, but not listed in the Wiki because it is 5m.  It might be too much current for an SSC. These would be addressable down to each 5050. If "resolution" is the higher concern over cost, this is the 5meter solution.

Those list as an IP67.  Am I correct that one should really NOT have those out where they get rained on, vs hiding up under an eve or gutter where they are basically dry anyways?

And if I am not mis-understanding, which happens a lot with this RGB stuff, when you say each led on the node can be addressed or grouped, are you saying there are 150 nodes if your group them, but if you do not, then you have 450 individual leds to control and 150 each of those is RGB so you could have extremely fine control like flashing the red led while the blue and green make a color on their own?

Could be some interesting effects.

Alan, IP67 is pretty good coverage although IP68 is ideal. Because the LEDs  are so close, the colors will blend to make another color.

These are 150 nodes that are grouped into threes. This is identical to the 12v ws2811's that fast eddy used in his show.
The sequencers will address than as nodes 1-50.

[arw01]

One more question to clarify the grouping:

grouped like:

 *
**

or grouped like

 *     *     *
** -- **--**


to make a three.  So a 30 leds per meter has 30 individual led's with 3 of each color, or has 10 of each color over that meter?

And when you say grouped you mean 3 leds at each spot is a node, or three in a row (so 9 individual leds) are a node..

[rm357]

These are RGB LEDs. One physical led contains a red, a green and a blue led within the piece of plastic. This allows you to do color mixing just like a pixel on the computer screen. This gives you the capability to generate over 16 million colors (24 bit color) on each node. In the strip in question, the nodes are grouped in sets of 3. Each node in the set is not addressable, all three nodes will display the same color. They're evenly spaced in a strait line.

So.
150 nodes in groups of three = 50 addressable elements.
...111222333444555666777888999000...
Each element requires 3 channels - one each for red, green, and blue = 150 channels.

[arw01]

Ok got that, so a 5050 node is different than these nodes?

How long are the three sets that are grouped into a node?  3" or something like that for each set of three?
