Title: Ray Wu source for the FirePix
Post by: Steve Gase on July 15, 2013, 05:08:24 PM
FirePix is how HolidayCoro is marketing these, but I wanted to see if anyone knew how to obtain the identical product from Ray Wu.

http://www.holidaycoro.com/Smart-RGB-Node-LayFlat-2811-100-Count-p/686.htm

Sean introduced me to the designer, and I loved the thought that went into these injection-molded lights.
As I understand it, the lights were "licensed" to various manufacturers -- including Ray Wu...
They are using UV-resistant wiring...
They have a place where you can use wire-ties without applying pressure on the wire...
The light housing has a directional arrow to show in/output directions...
The designer has had these underwater for 3 weeks without problems...
There have pre-installed male/female water-proof connectors on each end...
They have a flat back to allow mount them on a flat surface or on packing straps...
Optional C7/C9 covers...

Anyway, while I love HolidayCoro, I would like to work with Ray Wu to get custom spacing and leads.

Anyone have this info before I try contacting Ray?

Thanks!

I believe those are the ones. Also I think Rich here in Co Springs bought two strings of them from Ray.

Tying this back to the Falcon-16...

What is the maximum and recommended length of the lead wire before the first pixel in the string?

We have tested it at 25 feet without problems. I think 30 should not be a problem.

That's the exact setup (strings from Ray and Falcon-16 controller) that I plan to use for my mega-tree. Good to see that I am not the only one enchanted by the solution.

To suspend the strings in a megatree, the leading idea at the moment is to use strapping material, like Walter Monkhouse demonstrated.

Before I make that my final answer... any other great ideas? :)

Kevin, Rich and I all like the burning holes in strapping method. The strapping is a poly material like stuff used to make back pack straps. We use 1804 nodes from Ray and Rich has recently used a large nail to burn hole with great results. The nodes are tight and no glue is required. Last year I burned 1600 holes in one day. No zip ties  :).

I recall that now...  do you have a link to the poly material?

Found it in the old DLA thread:

David,

Wasn't it nylon strapping - not the poly stuff as it would split lengthwise when putting a hold it in.

With nylon when a hole is melted, the edges form a hard edge and seal up from unraveling etc.

If you plan on using the new c9 screw on covers, the node might be able to go on the bottom of the nylon, thru the hole, and the c9 cover screws down to sandwich the nylon between them?

Title: Re: Ray Wu source for the FirePix

The groups of 3 are for the flex strip format.
The pixel format with wires separating pixels are 1 bulb, 3 channels..
Title: Re: Ray Wu source for the FirePix
Post by: MyKroFt on July 16, 2013, 12:22:35 PM
Stuff u used was nylon strapping - wolven mesh, but when you made hole in it with heated spike it remelted around the spike and resealed the nylon so it would not come apart.

The plastic "banding" strapping that some used, will split vertically along the length of the banding....

with these new nodes from Ray, looks like 3/4" nylon strapping would be the best width.  Melt your hole, and then push node up thru strapping, and use a plastic nut on the stop side to mount it to the strapping, then node would never fall out of hole....

This is what Rich used.
http://www.rochfordsupply.com/shop/Webbing/Polypropylene_Webbing/Webbing_-_Heavy__1_inch_Poly/index.html

It is very similar to Nylon if fact I thought is was Nylon. Behaves the same as Nylon when you burn the whole.
Title: Re: Ray Wu source for the FirePix
Post by: MyKroFt on July 16, 2013, 12:31:55 PM
These light are the same as the indv pixel that DLA uses except everything is flat/waterproof, instead of wires getting pulled on and separate to let water in.

Those nodes have single chip per led, as these new ones from Ray do.  Holiday Coro calls them FirePix (trademark there), Ray Wu does not really have a specific name.

But up above, I linked to Ray's store the 50 ct and 100 ct versions.  Main difference in Ray's version is there is not 6' of wire from 1st core connector to 1st node.  Spacing is also a little closer (prob better for mega tree).

I am prob gonna get the 100 ct and fold in 1/2, the 100ct per node is $5 cheaper than 2 50ct.  16 100ct instead of 32 50 ct for my planned tree (1 falcon 16 controller).

Just make sure you don't order is current c9/c7 covers - they are the push on type - he has the new version which screw on to the threaded part of these new nodes.

Myk

With the webbing in place, will there be problems in getting the covers securely on?  Would the threaded covers be more or less likely to have problems over the push-on type?

Also, are the current nodes threaded? ...which is why you say not to get the push-ons?  Or will both cover types work and you are suggesting the threaded is just 'better' than push-on.


What is the consensus here about covers?  When I look at them I think they dim the light a lot, but I can also see an advantage in "softening" the harsh LED light.  but... with animated effects, do the covers hurt the crisp effects?

just not sure that 20% additional cost will improve the tree... or be something that sits in a box unused.

thx for your comments!

i think they would look good on eaves. More traditional look. I like flex strips for the accurate vertical spacing, One advantage of strings is you end up with a bigger tree. my 120 nodes was 14 feet with 1.3" spacong. using 4" spacing with 120 nodes on a string it would be over 40' tall.

Post by: David Pitts on July 18, 2013, 03:25:40 PM
I have some of the Techni-Color or FirePix nodes. If you are going to use them for a megatree I would suggest zip ties to mount them on banding material like Monkhouse. If you did use the burn method the hole would have to be big enough for the threaded part to go into the hole. Then I would use the slip on covers.

I think regular TM1809 nodes, burn method and slip on covers is the best way to go. And the cheapest.

I plan to use my existing 1-1/2" steel pipe, winch and crown from my original tree -- so I was going to request that Ray change the spacing. 

Instead of the current 85pixels from the old smart strings and their 3" spacing, I'm going to tighten it by using 100pix and 2.5" spacing.

"Cheapest" is good... but my season using the IP66 nodes still leaves me frustrated.  I want to turn a fire-hose on my display and know that it will continue to shine lights for months!  :)

I did have some IP68 nodes in the display, and had problems with them too -- even to the point of shorting out with a smoke plume right in front of my face. :(

Wow, I go on a two week vacation and this board gets all kinds of active.

1. David has the link right for the type of strapping I used.

2. I would not burn holes for these nodes (Technicolor/Firepix).  I would ziptie them.  The hot nail did not make a big enough hole for the base of these.  It's a lot of extra work to get the hole sized right.

3. I would not recommend using the 3/4" strapping if you are burning holes through it (not enough material left around the sides).  But it would be a good dimension if zip tying.

4. The C-9 push on covers look nice on these strips and stay on well.  However, I would not use the covers in conjunction with strapping.  The weight of the cover will cause the straps to twist around.  You could use covers if using a stiffer material like the emt conduit that Sean uses and zip tying to it.  Personally I like the look of my megatree without any covers.  Save the money for other items.  I do use covers for my house outlines and window frames.  I like the more classical look there.

5. the 100 count lights from Ray are $55 but there is also a close knock off on his site that are clear color for only $40.  These use the same exact mold as the others (I have both kinds).  You have to put your own 3 prong plugs on(not included) but save $15. http://www.aliexpress.com/store/product/100pcs-DC12V-WS2811-LED-pixel-node-with-transparent-wire-with-good-cold-resistance-ability/701799_825504922.html

Tom,

I have some of the knock offs.  In a string of 100, I found 5 that have an excessive number of air bubbles in them (it's hard to see through them clearly).  The air bubbles don't effect the IP rating (none of the chips/LED's protruded through the molding) but made the shape slightly off.  I can still get the slip on faceted c-9 covers on, but the smooth milky white c-9 covers required that I trim a little with a razor blade to make them fit.  There were no defects found on any part of the tabs for mounting.  They all look completely formed.  I have not actually hooked them up to power yet, so I'm not sure of the failure rate.

The clear version of these pixels is a "budget" option meant for indoor only.  It's a different type of plastic that is used, non-UV rated and softer.  The wire is also lighter duty and non-UV rated.  I am working on a newer "budget" node option for next season that will stay under the 50 cents a node mark but have a few more nice features.

Revive an old thread here.

Wondering if these are the technicolor nodes everyone is having a bear of a time with from Ray this season?

Would someone happen to have a link to the TM1804 you mentioned for the megatree?  I have a little 8-9 bush in the front yard that is perfectly christmas tree shappend that I want to realy cover next year.  200 nodes just does not do it, and I'm thinking 400-600 might do it. 

On your megatrees that really can show an animated gif, or the fine spiral details from nutcracker or LSP, how many nodes do you need to get the resolution going there?

Also looking for nodes that I can put into a massive pine tree year round and preferably controllable by the falcon products.

I'm currently going through my 368-pixel tree and pealing off all the silicon I tried to seal them with and then I'm going to try literally painting them with some outdoor enamel paint where the wires enter and leave the pixels.  It appears that most of my pixels are working after drying out in the garage, but I'm still pursuing a refund with Ray.  I shouldn't have to waterproof these myself and the ones that did have water ingress issues when I had the tree outside are just disasters waiting to happen.  I'm only hoping I can get a few nights out of these around Christmas Eve/Day when the forecast is calling for rain.

I think that the trapped moisture is not going to escape easily.  Once the electrolysis begins the deposits on the 12v pad to the data in or out pad help with conduction.  This damages the chip on the next or previous pixel. I would like to see the layout of redesigned pcb.  The 12v close to the data lines will cause failure every time moisture is present.  The moisture may also be coming in at the led.

I'm using C9 covers so I don't think I have ingress around the LED in mine.  I've run the tree for probably 48 hours since I brought it into the garage and slowly, over time, more and more pixels started working again.  It's still a disaster waiting to happen, but I'll try to get it bandaid-ed for another evening or two for my kids since they were more bummed than I was when it had issues because I was expecting the problems might happen.

I had the c9 covers on mine also.

Post by: CaptainMurdoch on December 23, 2013, 10:24:25 PM
Mine are pointed upwards slightly at maybe a 30 degree angle since they are strapped to EMT conduit for my tree so that makes the C9 a tilted hat instead of a bucket as in your case.  I can see how water would seep in around the threads and fill up the C9 if they are pointed down.

so if I read that right we have the pic at U1, three caps, a couple resistors and a mystery piece on the top left?

The caps are buffers for the signal on the data side mostly? Just curious why you need the buffer if I am correct in their function.

It's the LDO, filter caps plus a cap to reduce EMR on the output. Also the input and output resistors which we're missing on the original design.

Your wish is my command. Here is the pleminary new layout.

Got mine from Holiday Coro.  Actually I bought a few strings in early July.  I bought some later also. 

What regulator is going to be used on the new version? 

As for the layout,  a lot of pixels have the data running in the middle.  I have the square 2811s from Todd's store an I have some problems with moisture ingress and poor soldering.  They have the same layout with data line in the middle.

A placement of a couple more vias on the reg ground from the top layer to the bottom layer ground would help with thermal transfer.

The ones with the red and white wire?  I have 100 nodes on a little 8 foot bush with no issues, however it has been pretty dry, only evening frost and a little rain on Monday.  Everything still lit as best as I have noticed.  When I take stuff down in a week will run them in the shop for a day or so to make sure everthing is completely dry before putting it all away.

And I assume you mean a specific string from Holiday, mind putting up the link?  The sales start in a few days and I am collecting what I want to order soon.

Right now there are no links to the Firepix.  I probably will not buy any until the problems are worked out.  I can accept a small failure rate, not what I am experiencing now.  I am doing my best to study the problems and see if I can salvage what I have.  Here is the link to my Photobucket library where I show what the problems are on the pcb.

both those sure are ugly. i onlu used ws2811 12v flex strips this year and 1804 strings. just a few issues with the 2811's, mostly cold solder joint on the resistors. i think 4 failures out of 40 strings

I had similar failures last year on my Ray Wu square metal-backed pixels. The waterproof coating was too thin on some. My layout was on the roof at a mild angle, so water collected on the surface of the pixels and it rained several time plus morning dew or frost. Since 12vdc is applied all the time, it gave galvanic corrosion plenty of time to work.

I inventoried the damage and Ray replaced them. I put all new "better" square pixels up this year. They do have a heavier layer of resin and I have had no failures. I also have not had as much rain. When possible, I manually pull the power except during show times.

Perhaps an enhancement to the FPP (and I have not played with it at all if this in there) would be support for a couple three of the home automation web commands (just being able to call a script should allow some other linux utility like curl to do it) that could turn off power to the hubs and power them back up a bit before the show starts.

I did not happen to do that this year with my show on LSP, but could have used their built in batch command function to make the call to my ISY994 to turn off the outside lights.  Instead I just make a holidy variable that i set manually in the software interface and it turns off my outside lights a few minutes before the show starts for the night, and then back on when the show ends.  I did not put any modules on the ATX power supply plugs, but that would be a trivial matter to plan for.

You can schedule any Linux script to execute at this time.
