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!
