Technology Projects
 
A mechanised vehicle that stops when it drives over a dark surface.
200 mm in length, Made from 2 vacuum formed sections with a ‘light sensor’ and single transistor electronic circuit in base. Uses a 9v battery and motor driving Plastic wheels through a worm and worm wheel.

The ‘pull along’ toy with secondary motion.
400 mm in length. Made from 20mm wood with turned MDF wheels. A crank on the axle linked to a connecting rod causes the head to go up and down.

Pull along toy with secondary motion.
200 mm in length. MDF bird, wooden frame base, turned wheels, An eccentric on axle pushing a metal rod causes bird to pivot up and down. Painted in bright colours.

This bird deterrent uses a flashing light and a buzzer as the visual and acoustic deterrents. The horizontal shaft drives a cam through a reduction gear. The cam operates a micro switch which activates the deterrents. A low wind speed allows a flap to move forward switching another micro switch which switches on a motor to turn the cam . The entire structure is kept facing into the wind by a tail fin. A turned wooden block attached to a steel disk acts as a heavy base. The casing is made from aluminium. This deterrent worked very well.
A 3 blade propeller drives a cam through a reduction gear. The cam operates a micro switch which activates a flashing light and a buzzer which act as the deterrents. The body is made from brass sheet with the pivot from the stand attached near the front. The shape of the body and the position of the pivot ensure that it points into the wind at all times. Low wind speed allows a flap to pivot forwards thereby switching on a motor that will turn the cam. A clear polycarbonate top allows all parts to be seen with dismantling . This structure worked very well.
