A miniature race car is balanced precariously on a single pulley, speeding between two trees on a narrow zip line — will your car win the race?
The Basic String Car Racer is a simple project that consists of a battery, pulley, a reclaimed motor, and a bit of fence wire. The original string car was made from repurposed parts and materials found in Grandpa’s basement workshop. This version uses more commercially-available parts, but could be hacked with parts gleaned from old DVD players, for example. What modifications and improvements would you make?
