Thought this was very cool. I know not everyone reads the Makezine Blog (http://blog.makezine.com) so i thought I would post it here

I thought that was very entertaining, amazing with just 3 LED's. Thanks Eric :thumbup:
-
I thought so too. Now I gotta figure out how to build one myself :smart:

Hi Eric
:bugeye: :bugeye: :bugeye: :bugeye: :bugeye:
When you figure it out ,,,,make two ,,make me one :D :D :D ,,,,,,,,,,,,,,,,,,good Tiesto remix too :D
Cheers Rob

:bugeye: Now that was entertaining!!! But how does such a thing work? I mean, how does one control the spinning to make those 'shapes'?

It's basically a three dimensional oscilloscope.
The figures are made by feeding each axis with a slightly different rotation frequency - the same way one would feed two differing frequencies to the two axes of an oscilloscope to make Lissajous figures.

Pretty neat. I was surprised I got through the whole video. It's quite interesting.
I couldn't help being reminded of the "spinning ball of death" plot device seen in older sci-fi shows, where the hero has to get through something like that to reach the ships' nuclear device to stop the space ship from self destructing.
Anyway, quite a project, and fun.

I was mesmerized. What a hipnotic effect with that music playing.
Now if you want to build one take a look here: http://laserpointerforums.com/f57/led-orb-2-0-a-50012.html Scroll down a bit and he's got all sorts of pictures on how he built it. Very neat and easy to do.

A Whats-o-scope??? :scratch: :lol: I am not clued-up on electircs/electronics at all :)

Here you are .... have a play ... :lol:

Try the x-freq. and y-freq. at the same value, then increment one or t'other

That's a very innovative and well made bit of kit IMHO :thumbup:
Nice fine Eric :headbang:
If you double click the video you can get to his youtube channel and from there see many of the other videos... Well worth a watch :thumbup:
I went through the whole link from Bernd too.... Great to see how it was put together, I could figure some of it in my head but was stumped in the LED array itself.
Got it all locked up in my head now :smart:
Not too sure about the "easy" part though Bernd.... That frame work is a work or art in itself :bugeye: (lots of legless LEDs out there :lol: )
Try soldering that without screaming once or twice!! Heatsinks galore to stop the heat transfer from releasing other joints!
I liked playing with the ohsosillyscope too. Thanks BC :thumbup: I haven't done anything like that since college (mostly used on circuits though, wave outputs etc.... Forgotten most of that!)
All in all, another thing to store for the "possibility list " that hangs in the grey matter next to my "round tuit" list!!
Very enjoyable post :thumbup:

Ralph,
I say easy because you could use other material to make the project. I would probably use brass tubing, round or square. Build a supper structure like that used to hold the large signs over the highways. They are usally triangular in shape.
Let's just say that his project has given me ideas for a :proj: that I'll probably never get to. :lol:
Like you I've sahped the whole thing in my head, just can't get it down on paper. Seems like the arms don't want to work with the brain. :lol:
