PVC Pipe Multi Toy - Absolutely Simple

Step 8: Accessory #1: The Robot Face

To make the Robot Face,  you'll need:

1.   End Cap for 1-1/4 inch SCH-40 PVC pipe
2.   End Cap for 1inch SCH-40 PVC pipe
3.   Some black paper (87mm x 18mm) cut to shape as shown in the picture
4.   A Pin with Glass Bead 
5.   Thermocole Balls - for eyes - approx 10mm dia
6.   Black pipe approx 21mm OD (From an old marker/ electrical conduit etc)

Just follow the attached picture - it is self explanatory.
 
My Robot Head:
I've used 10mm Red LEDs instead of thermocole balls for eyes. 
There is a small LED Flasher circuit and a button cell inside the head.
The antenna on the head is a switch - The eyes blink when switched ON!
