I’ve been spending the last month on-and-off working on this exciting sculpture from ultra-talented Kate Raudenbush, who designed and is fabricating the main part of the 90′ sculpture. It is made of 240 ‘wings’ of 4′ x 8″ plasma-cut steel sheet and mirrored red acrylic. At the tip of each wing is a red LED.
(Starting the project…)
Kate came to me with these drawings and her original plan: the red LEDs would form a ’4-chase’ sequence. The budget is around $500 for all electronic parts, including LEDs, wiring, power, batteries, tools, etc. I decided to push the project a little futher: instead of a simple chase (which was well within reason), we would have each LED be individually controlled and PWM’d so that complex designs could be realized.
The biggest constraint (apart from the budget) is that all the electronics must fit in the square wing-support tube: .8″x.8″ and any wiring and connectors have to fit through a .5″ hole that was already drilled in the wings.
