There is various types of
LED balls on the market that are
cord fed. Shouldn't be too hard to modify them for rounding over and sealing up, battery and control. Shouldn't be a huge challenge. I didn't do them but don't think such a concept difficult. This much less make such a thing from scratch.
Studied such things recently while looking into some 24" blow up balloon
LED color changing gear for a quote. Got samples and bought a few to get in studying both of plastic 24" color changers and
LED supplies for the globes. Granted mine were to be rigged and not flying thus I could have a
cord. Probably 12 or 24v, but a battery could supply the balls easily with electronics package included. In my case there was a fan supporting the soft sides, in the case of the show, probably a hard or semi-soft side that doesn't need a fan to sustain it's fill.
Challenge for me was beam spread when held from the top in getting beam spread spread across the entire
globe.
For a beach ball, such a
cluster of free floating
power supply/
cluster of light would
throw off balance and create a dark spot. How did they do it? probably a
cluster of
LED's in the center of what ever was used, and perhaps filled in some way. After that, the challenge of
masking the electronics package and replacable battery package is a challenge. Am I to assume a single color in making it easier?
Could it other wise be
incandescent?
Just viewed the video... Interesting but seems like a fan
fed ball that don't light up with a one way
grommet that the color changing stick gets put
thru.
Its seemingly in the stick and given the black spot to it, this in color changing for that dia. gets done. Remove the
cord or what ever on the stick - easier to do than the ball in doing so or a true color changing beach ball. This especially with large dark spots on it showing.
Here I was engineering
LED color changing
microphone stands in figuring out spread coverage for a less dot of light and more spread coverage but not getting too large, plus fighting the fragileness of a 6'-5"
microphone stand in length to what plastics were involved in just shipping the weighted
base attached to the long stand. All kinds of stuff one can do with plastics and
LED's these days. Making them remote/battery is an added challenge but not much of one when one considers making a
portable water proof housing for the
power supply. Were it possible on todays quote, sure I would go battery. I would suspect that the show is coriegraphed to the timing of the color changing of this remote battery
unit that's self color changing. Looks like string/tie
line to me hanging out of it. The timing of this show as rehearsed as opposed to the need for
DMX live control over would
play a huge factor in how remote it can be.
If timed for results, one can go battery for it and coriegraph the use of it. If controlled at the light board, there needs to be a
wire or some form of wireless
DMX package that would need more black spot in doing so. If
DMX, you run a
cord that can also
power it up.
Simple enough choice, I would believe this to be battery operated and pre-programmed for color change control of it. Given that, still I think simple enough. Harder than that, appears to be a blown up ball of light. Could there be by use a
cord to the fan or another black spot for it?
