Title: Video request of Smart Strips in PVC
Post by: loveroflife96 on January 13, 2013,
Anyone have a video of smart strips or dumb strips that they used in PVC where you can see both sides of the PVC (both the LED side and the non-LED side)?  I have an idea for a project for next year, but wanted to see what it might look like before diving in...

each arch is 8 sections of dumb flex strip that I powered with the chips from smart string nodes.
there was no way to "point" the dumb strips, and each section isn't facing the same way inside the pvc.
safe to say..  1/4 of the sections are facing you, 1/4 are facing away. 1/4 up, and 1/4 down

Thanks Chris...the dispersion of the lights looked pretty uniform.  Would you say this was the case in "real life" as well?  I was looking to utilize two dumb strips back to back inside PVC to get dual colors on a project but after this, I think I might just have to go smart strips and utilize some nutcracker effects to get the look I want.

I was a little nervous, as I only tested the lights inside and when they went outside, they didn't go on, until it was time to be part of the show.

It's really been the highlight of this year. 

I was thinking of toying with the idea of placing some dumb strip back to back inside to see what kind of look I could get.
I was also thinking of trying regular smarts string nodes inside to see what they would do (for this, I have my nodes zip tied to lay flat with the cables, rather than stick out.

I haven't tried those ideas yet.

If you happen to try the dumb strips back to back, if you could video it, it'd help me out a lot.  I'm concerned that if the dispersion is pretty equal, then the two strips may "merge" colors and create an "ugly" color through the PVC when two different colors are used at the same time.  I'm going to try the node idea with my smart pixel nodes I have now to determine what the dispersion looks like though mine I had custom made with 10" centers, so I know I'll have to get some more that are closer together.

I've got the smart string flex string inside of pex tubing in my arches.

What size Pex did you use?  I bought a piece of 3/4" pex 10 ft long, but the strip seemed to be too tight.  To get 1" I have to buy a 100 ft roll of Pex.  I tried a 3/4" piece of PVC and that works ok, but I'm thinking the flexibility of Pex would be better.

Its 3/4.  The end caps are what make it tight, it you take one off the strip it will slide in much better.  Once all the way in you can push the other side in although its tight and then push it enough so the other side comes out to put a cap back on.   

My arches are half a strip so I used the cut ends to slide in the pex before I put caps back on.  Its the silcone sleeve that makes it tight.

if you're putting it in it's own protective sleeve (the pex) why not just get the flex strips without the silicone tubing?

Yep you can, I just left it on since it fit and I had the cap to put back on, just another waterproofing step I guess.

Are you mounting with rebar?  Does the pex need support?  I am thinking pex ss arches too but not sure best way to mount.

with rebar supports on each end, i can see pex being sturdy enough in 10ft lengths or shorter.  it's when you want to have the really big arches, where i dont rally think pex would be strong enough.

i bought 5m dumb strips at about $11 that are NOT waterproof for use inside thin-wall PVC.  the reason i went with that material, what that the pex seemed to be more "led's shining individually, as opposed to the well blend of the PVC.  plus, i can place the ssc inside the pipe with the leds.

next year, i'll have a 10ft section with leds and ssc inside, then a coupler, then a short piece of PVC with a hole in the side for the cat 5 cable to go in.
I can disconnect the arch for repairs, and still have the entire assembly (plus the wire connections well protected from water)
with only the jacket of the cat5 cable exposed to the elements between the pipe, and the battery ox holding the hub, there's no way for water to affect operation.

You said you made up eight sections, is that eight strings of dumb strings and how many nodes in the dumb string and what is the length of each section.  Where did you get the tubing?

Yep mounted with rebar and pipe clamps.  My arches were about 5 ft long and no support needed, I actually had my ssc mounted at the top of each also.

Here is a picture of one of the ends.

me? yes, eight sections...

pvc (the same thinwall pvc as the ssc controllers use) from Lowes
tm1804 chips from Ray
caps, resistors, adapter pcbs from ebay
3wire cable (from another member here - but ultimately from Ray)
dumb strips from ebay

picture of each section (i added 3core connectors from ray to each section, to quickly change out a defective section)
(http://i1059.photobucket.com/albums/t438/chrisatpsu/IMAG0372_zps113f7e27.jpg)

Each section is 3 pieces of (3led sections of dumb strip) for a total of 9 "5050" leds
(http://i1059.photobucket.com/albums/t438/chrisatpsu/IMAG0373_zpsfca93487.jpg)

on the end of each section is a taped up cube that contains the TM1804 chip to control the colors of the section of arch. (one chip power all 9 leds * 3 colors)
