I want to make these so bad. Any ideas?

That does look good. I'll never have anything like that, but I can still dream! :D

He does kind of tell what he does. It looks to me like he is using rope lights spliced together and a strobe or C9 on the end... They look really cool!

looks to me like his ball at the top is comprised of 10 sections, he says there are 60 needles so each of those 10 sections would have 6 needles. my ropelight has the bulbs every 1" he says there is 127 bulbs per needle, so i get each needle being about 10.5' long. if you look carefully in the 2009 photo section you can count 11 sections along a couple of the needles.

now HOW he wired it all up is the question since it appears there are 11 sections plus strobe on the end thats alot of wire to be running along what appears to be a 1/4" steel rod frame for the needle.

or you can simply go here and buy it for 3K dollars each. http://www.santaslites.com/Fireworks.html

I saw something similar a while back and someone had posted a link to some "porcupine fish attractors". I was looking at them to use in a 4th of July show. Not sure if this was the same that I had looked at then but if you Google around there are several. Here's one: http://www.cabelas.com/cabelas/en/templates/product/standard-item.jsp?_DARGS=/cabelas/en/common/catalog/item-link.jsp_A&_DAV=&id=0047096122249a&navCount=0&podId=0047096&parentId=&masterpathid=&navAction=push&catalogCode=UK&rid=&parentType=&indexId=&cmCat=netcon&cm_ven=netcon&cm_cat=Google&cm_pla=porcupine%20fish%20attractor&cm_ite=netcon&rid=2146251080&hasJS=true

These aren't the same as what this guy has but you could probably do something similar.

There was a smaller version called a star-burst described in one of the newsletters a while back:
http://www.doityourselfchristmas.com/newsletter/pdf/jan2009.pdf

Seems like it wouldn't be too difficult to make this new variation - structually there's a pole up the middle, then thick wires attached onto that, and set at rigid angles. The pole part could probably be done using any of the mega-tree techniques.

Then for the wiring, you could put a Renard + SSRs up at the top so you only needed to string a power cord and a cat5 cable (or you could go wireless so you would just need a power cord). Depending on how many strings you wanted to have turned on at a time, you might need more than one power cord if you are using incandescent strings; LEDs could probably all be driven off of 1 (if you use the terminator resistors and don't encounter flickering problems), otherwise you might also need to split them across multiple power cords.

For the sequencing, it looks like it would be a combination of a tree (if you hang strands downward) or a column/arch (if you just wrap the pole), and then individual channels up at the top, like a bunch of candy canes or mini-trees (depending on whether you wanted to use them individually, or in clusters to form patterns).

I also saw a spinning version of something like that once (I think it was on a Burning Man web page) - it had about 3 splines attached to the top like a propellor, with lights on it, and then it would spin around. In principle, like a big SpokePOV turned on its side.

I had an email from him on my home pc. He purchased them. This is not the site he ordered from but the same product I am pretty certain.

He specifically mentions 24 more channels for this years display and the fireworks displays just happen to be 12 channels each. So there ya go. It is for all intents segmented light rope in some sort of rigid construction, (maybe fiberglass rod) that has what looks to be 5 light segments plus the strobe on the end. Add 6 segments for the launch lights and you have 12 channels, each.

All I can say is WOW. Would be interesting to see what some of you guys can come up with on a "DIY" scenario rather than buying the entire setup.
