Stackable Light Tower

Stackable Light Tower.

This is a simple design for a Light Tower.

The Lenses for this Light Tower are stack-able so you can use one
layer and a three color LED or two layers with separate LED's or three layers with three different LED's.

I'm prototyping a radiation monitoring system using a SparkFun Geiger counter, an arduino Uno, a solenoid to lock a swing gate and a Light tower to signal "Safe to Pass" or "Hold while your shoes melt".

I may use a MicroView for text output or an LCD for messaging for mR/Min etc...

You can put a piece of aluminum foil on the upper and lower surface of the separators for a reflelective surface.

Instructions on how I made the Lens part are given in the image sequence above.

You can use Clear ABS from Octave, for the lenses but I printed the lenses on a Form1+ using clear resin V2 and the other parts on an UP!3D.

The electronics are up to you but ultra-bright LEDs work geat and are controlled from the
Arduino Uno with a common ground and Digital Outputs to control the LEDs.

If you want you can print out a lens, cut it in half and create a mold to cast lenses using
water clear resin and translucent red or green Dye from Polytek:
