Picture of 3-dimensional Star Cluster: Acrylic + LED light sculpture
This instructable will guide you through the process of making your very own star-cluster from LEDs and acrylic.

I made this piece for my electronics final project at college and had access to a machine shop. This instructable assumes that you have access to similar tools.

This project was very much inspired by http://www.instructables.com/id/working-progress-n-how-to-make-a-multilayered-a/#step8. 

Step 1: The Materials

Picture of The Materials
• 80 LEDs (Amber, 3000 mcd)
• 80 68 ohm resistors (or other small resistance of your choice)
• 80 1k ohm resistors
• 10 4051 multiplexers
• 20 7404 not-gates
• 30 16-pin sockets
• perforated pc board
• lots and lots and lots of wire
• arduino uno
• 5v power source
• 3 layers of acrylic board, 20” by 20”
• 1 layer of plywood, 20” by 20”
• 4 feet of ¾-inch diameter acrylic rod
• 1 foot of ¼-inch diameter acrylic rod

• soldering iron
• solder
• wire-cutters
• wire-strippers
• lathe
• drill press
• band saw
• 1-meter telescope (optional)

Is there any way to slow down the flashing?

this is crazy awesome\, but must it be made using an arduino board?

Definitely not! I used the arduino because it's what I had to work with, but I think using a TTL square wave and a few JK flip-flops would also do the trick.

super cool I would build this if I had the time and patience.
