leaping arches

Recommended Posts

[align=left]
Hi There, I have a question about leaping light arches.[/align][align=left] I have seen some being constructed on UTube and, for example, one person had 9 strings of lights per arch. Would this mean that there would be 9 channels of a LOR contoller used to get the fx as seen. If so, if I had 4 arches with 9 stings of lights per arch, that would be a total of 36 channels used, am I right?? Or is there a special technique used?? Thanks..

Yes you are correct, that is one way to do it and if you can afford to dump 36 channels on such a small element of the display then go for it. The advantage is you have full control of each arch. The arches I am building are 5 sections, each section will share a channel on each arch. I don't have full control so each arch will mirror one another but if you are creative you can make some nice sequences. So I will be using 5 channels for my 4 arches which saves a lot of channels compared to 36. You will notice people will build them with odd number sections 5,7,9 reason being is this way you will have a section top center with even amount falling on each side which will make the leaping effect more effective. I have seen one person with 4 section arches that look good but only one. Otherwise you want to look at 5,7,9 sections. Hope this helps.

Hi texan 78, Thanks heaps for the quick reply.Yes, just as I thought.. Will try out your ideas and see if I can save a few channels. Cheers, Mario

I used 8 channels per arch (3/4" ID, ten foot sections) on mine.

One way you can conserve channels (at the cost of extension cords or zip cord) is to have two arches in separate locations using the same controller. Yes, they will burn at the same time, but if you place them strategically, no one will notice.

Another sharing a controller technique is to have them go in opposite directions at the same time. For instance, one arch goes north to south and the other goes south to north.

When spaced across a display, it will generate a look that you have more channels than you really have.

Being able to do this will depend on how you have your arches set and how you want them to look.

yes you can. like dale posted.

as far as colors, your going to eat up a lot of channels

You can but your are limiting your self to one effect. You would not be able to control the speed or direction.

Someone on PlanetChristmas posted a thread on "doubling your channels" that involved a relay switch to change which set of channels is being controlled. It cost about $40.00 in parts and the losss of one LOR channel to control the relay. The only disadvantage was it was an either/or not both arches at the same time.

Hi Mario,

Last year I did 4 arches, 8 segments each, but had them wired as two pairs of arches for 16 channels total. We live on a corner lot and I had 2 arches on each street frontage. I was very happy with the results. My arches were each made from 2*4 metre lengths pvc with 4 segments on each length. This allows easy pull apart for storage. Because my arches are mounted above our fence, the lighted length is just over 3 metres each half, with the other 900 mm being used for attachment to the fence. (see pic)

This year I am adding a second colour ( and another 16 channels ) so I will have clear minis and blue LEDs with separate controls. Because the LEDs are brighter (and more expensive), I am using only half the number of LED lights relative to the minis. Tests so far look very promising but I have yet to rewind my first arch.

Geoff: Did you change the intensity levels on your leaping arches when you went to LED's. If so how much? I have made a 9 channel arch with 140 LED's per section and the comet tail effect looks like fading sections that are easy to see.

I'm still putting the 2008 two colour arches together, but I plan on using dimming with both the LEDs & the minis. LOR dimming on the Minis worked fine in 2007. Being in Australia, the lights come with low voltage transformers - 24V. I used a PC LOR board to control & dim the minis last year.

I plan to get some DC LOR boards at the June sale for control of the arch LEDs and other LEDs. My LED strings came with 24V DC plug packs, but the response on power down is too slow probably as the packs includes filtering capacitors, so I have bought 24V switch mode power supplies to power the LOR DC boards.

My initial testing looks good, but I won't have a fully operating arch til July or later.

Regards - Geoff

Geoff,



Sorry Silly question.....newbie here........living in PErth........where do you ge good LED lights at a decent price in Australia....or is that an oxymoron? :)

Do you have a website to view your Xmas lights?

Guys,

Check out Lowell Fuher's (Papa-LF on the forums) how to video for the leaping light arches. He did a great job. I think he is out of his winder kits that he uses in the videos, but if you approach him, he might sell you his personal copy. Here is a link:

This will hyper link you to his site.

Folks, after seeing these photos, I began to wonder how delicate these arches are when using those incandescent glass mini bulbs? It seems that if the arches aren't handled with care, and they fall over during setup, some of the bulbs would break.

I have not built my arches yet, but I was thinking about using some of those thin rope lights from Walmart and wrap them tighly around the pipe. I saw some in the store for $7 that were 18 feet long with 216 bulbs. If I did the math correctly, 18 feet wrapped around 1 inch pipe would yield a segment about 66 inches (5.5 feet) in length.

Anyone else using rope light?

For reference:

In the UK I purchased most of my lights from http://www.lights4fun.co.uk

They are the most reasonably priced that I can find!

I have put ten sections on my arch this year. The arch is about 6/7m long - 18/21ft in old money. All one colour.

I used 1" PVC cable trucking to create it, but its rather flimsy to say the least (it was the best I could come up with at the time). Any suggestions on how to stabilise the entire mass? Is there a well known trick that I can copy or is it trial and error (Im guessing thats what it is!)

Regards

Rob

Maybe you could add a 1/2" PVC conduit *inside* the 1" conduit. Not sure if it would fit, but if it did I would imagine that would make it less flimsy.

Sorry guys, here is a copy of the post with the links.

I used 1 1/4 Elec conduit for mine. I have the large version using 2 10' sections. I also used LED due to the fragile nature of incandescants.

I had so many requests for more information on the Leaping Light Wrapper Kit - I have produced 3 Videos -

  1. Quick Demo and Introduction - just under 3 minutes http://video.google.com/videoplay?do...99776482&hl=en
  2. How-To video part 1 http://video.google.com/videoplay?do...07066258&hl=en
  3. How-to Video part 2 (split because of length) http://video.google.com/videoplay?do...17375687&hl=en

Of course there are many different options to winding lights - the way I have worked out works for me - hopefully you can glean from the work I have done. The wrapper kit is available from me - for a price please email me here or the address listed at the end of the demo video.

I'd like to jump in here with a question for you arch experts out there.

How are you mounting the arches into the ground so they stay in place? Stakes? Spikes? Prayer?

I can see that many folks use galvanized wire to support them vertically, but I am curious about how you mount the base. Tnx for your wisdom

Thanks for the response Jeff.
Thought about that, and also the possibility of "injecting" the 1" conduit with a foam filler or concrete (obviously bend it to shape first). I think I will end up fixing it to posts and sinking it into the garden, possibly with some hefty uprights to keep it all in place. Thank God for Woodwork Class. And next year I'll look to making slightly smaller arches.

Richard - I think prayer could work well. After all, some would argue if not at Christmas, when? Failing that, wire and posts and sticky-back-plastic, wire wool, and anything else you can get your hands on.

Regards
Rob

Mine will be rebar stakes 24 inches long with 12" in the ground. For stablizing the arches I will be using black fishing line 20 lb test. Will put one or two stakes in the ground on each side of the arch and string two lines to these stakes.

Dennis, that sounds like just the ticket! I like that idea. See, I knew there were folks out here a lot smarter than me. Now that you mention it, rebar stakes should be cheap and available. I'd hate to think I'd be stuck using those flimsy plastic stakes that always break unless you stick them in mud ;-)
