Introduction: How to Build a Dalek Eye

This instructable will show how to build a dalek eye. The design I used was based off of the 2010 version of the daleks.

Step 1: Parts Needed

For this project you will need 9in of steel tube, approximately 3/4in in diameter, 2 LEDs (one yellow, one blue), a 100 ohm resistor, various wires, a fish tank marble, and dalek eye shaped pieces. I recently bought a 3d printer so I designed and printed them. I have included the stl files. (the back of the eye was having an issue peeling up, so I added a flat sheet to the bottom)

Step 2: The Eyestalk

Cut a 3/4 in piece of the tube off and set it aside, this will be used later. Drill holes in the tube for the wires. Three wires will be used to power the LEDs, these do not need holes drilled. One of the wires I planned on upswing to hang the eye in a display, so I drilled two hole to make it extra secure. The holes should be drilled an inch from the end of the tube. Once the holes are drilled, thread the wires through and put a bit of glue inside the tube to hold them. You want your three power wires going from one end to the other.

Step 3: The Electronics

The two LEDs have the positive leads soldered to the resistor. The resistor is then soldered to the red wire. The negative leads are soldered to the wire that matches the LEDs color. When an external battery is applied, the eye is able to glow either blue or yellow. (Red wire goes to positive, whatever color you want it to glow goes to negative)

Step 4: The Eye

Epoxy the marble on to the 3/4 in piece of tubing from earlier. That then gets glued into the eye. Epoxy the plastic parts in their appropriate positions.
