Step 2: BEAM Symet Parts
To build this robot you need the following parts.
1x resistor between 1k and 10k ohm
1x 2n3906 transistor
1x 2n3904 transistor
1x motor (the fatter and flatter the better!)
1x solar cell (volts vary depending on motor)
1x aluminum wire
3x identical capacitors between 470 - 4700 micro-farads
1x flashing LED or blinking LED (no exception!s)
heat-shrink tubing (to get traction by adding to the motor shaft)
Step 3: Preparing the Motor
The second step is to get your plyers, sandpaper, etc... and stratch the motor body until you see a different shine of metal appear. This allows the solder to stick to the motor body so we can solder on our capacitors. after you have stratched the motor enough then solder the (-) capacitor leads to the motor body.
