Jim Saul Posted September 11, 2011 Share Posted September 11, 2011 OK so I watched Brian's video of 4 CCR circles http://vimeo.com/16467508 and was amazed.I'm wondering if it is possible to do it with 2 ccr's.Has anyone tried making 2 circles from once CCR?Will it work?Anything I need to watch out for?

Ken Benedict Posted September 11, 2011 Share Posted September 11, 2011 Yes, I would like to know more details also; do the circles start on the left or the right? Link to comment Share on other sites More sharing options...
ainsworth Posted September 12, 2011 Share Posted September 12, 2011 Jim:LOR states that the CCR can be bent around a 3' diameter circle with some buckling. At that diameter you will use about 9.5' per circle, so there isn't enough ribbon to make 2.However, if you mount the CCR on it's edge you could do 2 circles with no problem. George S turned me on to this with the spiral CCR. On it's edge the CCR can be bent to a 3 inch diameter with no problem, so doing a 2.5' diameter circle is no problem.Ken:I would start the circles on the bottom, that way the control cord is hanging down. The "movement" of the circle is controlled by sequencing so, other than ease of sequencing, it wouldn't matter. Link to comment Share on other sites More sharing options...
Dennis Cherry Posted September 12, 2011 Share Posted September 12, 2011 My display is the one Brian used for the videos. We started just before Halloween with the construction of the circles and did the first videos on Halloween night. Brain came back a week later and did more videos with some other songs and had to construct the circles again, only took about 30 minutes to put is back up the second time I went to a friend who also does a large Christmas display who had the equipment to build the frames out of 1/2" square steel stock.Brian requested that the circles be exactly one CCR so that figured out to be a little more than 5 feet diameter. Also the starting feed point for the CCR's to be on the left center of the circles.The circles are held in place with just hose clamps and worked out great installing and taking them down.Overall length was slightly over 21 feet.

Dennis Cherry Posted September 12, 2011 Share Posted September 12, 2011 Clamping area. The right ribbon shows the start/end overlap of the ribbonThe left ribbon is the 25-26 pixel point inline with the 1/50 right ribbon point.the hose clamps are behind the ribbon.The garland and flowers coverup the controllers hidden in plastic boxes.

Jim Saul Posted September 12, 2011 Author Share Posted September 12, 2011 Ok so IF I try this with the 2 CCRs that I ordered, I would need to make 4 circles each with a 2.5' diameter.This means that the CCR cannot be mounted to the front surface of the circle. But, thanks to George's innovation, it is possible if I put the CCR on the inside of the circle instead of the facing the street. Is that correct?Using the inside of the circle will require me to cut the CCR and solder in leads to do the 180 degree switch from one circle to the other.Thanks, lots to think about ... Dennis, great job on them my wife and I have watched that video many times now. Link to comment Share on other sites More sharing options...
ainsworth Posted September 12, 2011 Share Posted September 12, 2011 You are correct, mount the CCR on the inside or outside of circle.You don't have to cut the CCR as long as the circles touch (or almost touch) each other like in the video. If the bottom of the circle is south and the next circle is touching the east point of the circle. Start the CCR at the east point and go clockwise around the circle on the outside, when you get back to the east point "jump" the CCR over to the inside of the second circle and go around it counter clockwise. The only reason to switch from outside to inside is so the leds are not mounted against your circle. Don't know that it really makes any difference just my thoughts.The CCR will be a figure 8 on it's side (infinity symbol). Since you will have to have a support frame of some kind to hold up the circles, you can use the frame to run the cords to the ground and they won't show.Sequencing will take a little getting use to. Say you want both circles rotating clockwise. On circle 1 you would chase down pixels 1 to 25 while circle 2 would chase up 50 to 26.Interesting idea you have come up with. I will be interested to see them in action if you build them. Link to comment Share on other sites More sharing options...
Jim Saul Posted September 12, 2011 Author Share Posted September 12, 2011 OK, I'm tracking with you now.Since 1/2 conduit is $1, I think I can safely blow $5 and see how it works. Now I just need to break out the torch CCRs should be arriving in a few days. Link to comment Share on other sites More sharing options...
Gary Blair Posted September 12, 2011 Share Posted September 12, 2011 One question - if the CCRs are mounted on the side and their viewing angle is only 120 degrees - how will this look from the front? Has anyone tried this? If you are viewing from one side or the other (not directly in front)it would seem to me that one half of the circle would appear bright and the other side may not be seen at all. But maybe I'm just confused! Link to comment Share on other sites More sharing options...

If you are viewing from one side or the other (not directly in front)it would seem to me that one half of the circle would appear bright and the other side may not be seen at all. If you're far enough at an angle, one side does look brighter than the other. I knew this was going to be somewhat of an issue, and that's why I painted the board the spiral is mounted on a bright white for maximum reflectivity. Seems to have worked. Might be a different story without a backing like I have behind the CCR. But maybe I'm just confused! It only gets worse as you get older... :D Link to comment Share on other sites More sharing options...

Jim Saul Posted September 13, 2011 Author Share Posted September 13, 2011 I'm going to try this next weekend.I'll take pictures and post them.The plan is to cut a circle out of 1/2" sheetrock, then use that as the pattern to mold the PVC around.I will have to play around with the exact size, but it is about a 30" diameter.

Jim Saul Posted September 25, 2011 Author Share Posted September 25, 2011 I have put together a proof of concept using lots of electrical tape now to wait for dusk to see what it looks like.I used 1" black polly water pipe from home depot to make the circles. it worked very well because it comes rolled into circles and naturally wants to retain that shape.more details to follow as time allows. I did take several photos so if it works I can put together a tutorial. Attached files Link to comment Share on other sites More sharing options...
bretk Posted October 7, 2011 Share Posted October 7, 2011 Jim,Enquiring minds want to know, how didi it work? video, construction details?Thanks, bret Link to comment Share on other sites More sharing options...
TJ Hvasta Posted October 7, 2011 Share Posted October 7, 2011 If you merge this idea with the dryer vent thread, using the vent tube would allow you to mount the CCR along the inside or outside of the hoop, and the vent tube would diffuse the light enough where you wouldnt have to worry abt the 120deg viewing angle, right?

bretk Posted October 7, 2011 Share Posted October 7, 2011 Hmm, that might make a nice diffuser. Too bad there isn't something smaller than 4" dia dryer vent tube . A 2" dia opaque tube would be great Link to comment Share on other sites More sharing options...
TJ Hvasta Posted October 7, 2011 Share Posted October 7, 2011 There is 2" - 3" white pool pump hose, also corigated, you can try.. slit it down one side, to slip it over the hoop Link to comment Share on other sites More sharing options...
Jim Saul Posted October 7, 2011 Author Share Posted October 7, 2011 Sorry, I've had a stomach flu and been waiting for S3 to program them. I have all of the photos and measurements in my cell phone. I will put together something with the assembly photos as soon as I can.The 120 viewing does not seem to be too big of a deal so long as you put the circles at the correct height for sitting in a car.

George Simmons Posted October 7, 2011 Share Posted October 7, 2011 Jim,If you're going to be putting those circles where they're meant to be visible from only one direction, I'm thinking you could probably rotate the ribbons a bit more toward the front and virtually eliminate any viewing angle issues. Be sure you post a link as soon as you get some video - I'm looking forward to seeing it. With those smaller circles you might be on to something I can steal for next year...
