Please note, the buggy has undergone minor changes since the original photographs were taken. Refer to the new file titled "Buggy Assembly Directions, August 2009" for essential modifications and clearer assembly instructions. This document will help you understand the motor and drive mechanism of the solar cell buggy, the use of the croc clip switch, and how energy from the solar cell is stored in the capacitor. Ensure you maintain a minimum distance of 10cm between the hot lamp and solar cell while operating.

IMPORTANT CHANGE THE BUGGY HAS BEEN SLIGHTLY CHANGED SINCE THESE PHOTOGRAPHS WERE TAKEN PLEASE SEE NEW FILE “BUGGY ASSEMBLY DIRECTIONS, AUGUST 2009” FOR MINOR MODIFICATIONS MADE TO BUGGY AND CLEARER ASSEMBLY INSTRUCTIONS
Welcome to the solar cell buggy. Before you explore the buggy, make sure you know how it works…
The motor and drive mechanism The croc clip switch (shown in the switch off position) A capacitor is used to store energy DC power socket
Take care: don’t have the hot lamp too near the solar cell. Minimum distance is 10cm. Storing energy. Energy from the lamp is transferred by the solar cell into the capacitor energy store. >10cm Note that switch is off (croc clip disconnected)
The solar cell buggy with drive circuit complete. This buggy is rolling… Switch closed. Energy is being transferred from the capacitor.
