Picture of Cyclops Walkbot
This is a single PCB about 1" square large with a miniature switch, LED, cell phone vibrator motor, 3V battery and four 22 gauge wire legs. When turned on, it does an excited wheeling dance. It's a simple project, but the act of assembling something that makes noise, moves and has a light that seems to thrill both adults and kids alike.

Before soldering everything, it's very important to identify which side of the PCB is top and bottom. The top of the PCB has the words "Cyclops", "M1", "R1"; and the bottom just has "+" and "-" markings.

Vibrating Motor
On the top of the PCB, there is a label M1. Take the vibrating motor and make sure it is in the correct orientation. Solder the four leads of the motor to the board.

Solder the LED
Before soldering the LED (to the top of PCB), you must position it with the correct polarity. The LED slot has a circle frame labeled D1. Inside the circle there is a square pad and a circle pad, to correctly place the LED with the correct polarity, the LED with the shorter leg should be soldered in the square pad and the longer leg in the circle pad.

Solder the Resistor
The 680Ω resistor (top of PCB) will be soldered in the rectangle frame labeled R1. Polarity is not a concern for resistors.
