Summary
[edit]DescriptionLased LED light towers - 3881682653.jpg |
English: I wrote an algorithm for the laser that outputs cut and perforation vectors for a folding light tower with almost any dimension. The materials are watercolor paper and a little glue. The tower's top can be removed to expose a place to attach a magnetically fastened LED light and battery. The starfields require special calculations so that the light finds its way through two folds of paper.
Here they are with the lights on. A modification of this old project.. |
