Do people still get beat up for doing stuff like this? I hope so. Regardless, this isn’t a christmas tree.. There’s no place for ornaments..

hi there, it’s a concept idea of a futuristic Christmas tree,
if you have a better idea for a futuristic Christmas tree, bring ‘em on!

Yes, it’s all very nice, but is it cat-proof?

We are thinking of an see-through plastic enclosure for it so it can hit people, dogs, or cats while in operation…

[...] While we are trying to make our DIYs that will be a hit hopefully and does not get some negative comments from digg, you can check out Top 10 Christmas Project Ideas from Hackedgadgets and forget about the world. [...]

if it really only shows what I get to see: what a pointless video! and, uh, learn to, uh, learn to, uh, talk!

[...] Created by Zedomax, this nifty LED Christmas tree is made from parts you can pick up at your local Radio Shack or electronics store. More information here. Video after the jump. In this special Christmas edition of Zedomax DIY122, we will show you how to make the geekiest Christmas Tree in the world using LEDs, bathroom pipes, and an embedded cubloc module. Well, this can really be made into other cool looking POVs. It’s really up to your imagination now [...]

[...] Hier handelt es sich um ein nettes DIY-Projekt, über das ich so bei meiner morgendlichen Lektüre gestolpert bin. Zwei LED-Leuchtschläuche sind auf einem rotierbaren Untergrund befestigt und werden durch diesen gedreht; wenn die Drehungen gleichmässig sind, sieht das ab einer bestimmten Geschwindigkeit dann so aus, als würden farbige Kreise um die Mitte schweben, dieser Effekt ist im Englischen als “persistence of vision” bekannt (ich kenne leider den deutschen Ausdruck dafür nicht). [...]

I was reading the howto and wondered if you really need to seperately wire every one of your green leds. AFAICS, you can just hook all their anods together, just as you did with the cathodes. You can then put a single resistor in series with all the green leds (which are in turn in parallel).

Normally, you would calculate the resistor value as (Vsource - Vled) / ILed, where Vsource is source voltage, Vled is led voltage and Iled is typical led current (last two depending on the type of led).

Now you can just do (Vsource - Vled) / (n * Iled), where n is the amount of leds you connect.

Oh yeah, you can do that for the cathode side, but you still need to connect the anode side to i/o pins if you want to control it. That’s a very good idea! Will implement that in our next DIY!

You can also colorwash the Christmas tree with additional mood lights from http://www.a-r-e.nl

Well, you can really only do this if you don’t want to control them seperately (putting the resistor at the anode or cathode won’t make a difference…). The calculations I made assume that all leds are turned on. If some are turned off, the others will get more current.

[...] Don Stratton at Atomic Fireballs has improved on our Christmas tree with structural designs! Although his tree does not do a POV like ours, we gives him two thumbs up for the nice pine tree structure. About 2 weeks later MAKE Magazine’s RSS feed had a headline about some guys who made a POV Christmas tree! Oh well, this happens to me all the time; come up with a trivial geeky concept and somewhere between two days and two months someone posts video to YouTube of it working away. Hey, million geeks with a millon microcontrollers and all that. Quite often the person who actually developed the idea does a nicer job than I would have and I feel like a hole in the space-time continuum has been sealed, but this time… well, not only do I have some free time on my hands but the fine gentlemen who beat me to the punch on this missed only ONE absolutely critical detail, and the difference between what they did versus what I did virtually defines the whole look of what you can now call a tree. At the end of this article I will sum up the only significant change to the concept those gentlemen used in their project, and you can be the judge of how important it really is to your own efforts to build a POVTree.

nice thing, ony hold your camera still next time, i almost puked.

hi all. nice blog. its very ineresting article.

This is cool idea!!!!!!!!!!!!! I like this project. You can find something like this from http://www.lunaraccents.com/technology-programmable-LED-controller.html
also but if you want to do some project with them, make sure if you have high budget!
