Inventors Kit 5: Solar Light

Posted by Matthew Little on

We are going to make a light that is powered by the sun! We need to use the little LED which is in your kit: it has a clear plastic case and two small wires. An LED is a Light Emitting Diode. It is a very efficient light. You might see some on devices around your house. They can be in lots of different colours: you probably have one on the front of your TV or on a radio. Some torches and house lights also use LEDs now. An LED has a positive (+) and a negative (-) lead and...

Inventors Kit 4: Solar Spinner

Posted by Matthew Little on

We are now going to use the solar panel to power our motor with the sun, no batteries required! This time we want to use two cable connector block to connect the solar panel directly to the motor, as shown here. If you put on the motor connector to the motor then you can see the motor spinning more easily. Takes this to a window or (if you can) outside and try pointing the solar panel at the sun. What happens to the motor? Does it start to turn? If not - is it a sunny day? Are you pointing...

Inventors Kit 3: Spin-Art

This time we will use the motor to make a spinning wheel, which you can use to show off patterns you design or that can be used to make 'spin-art'.

You might also want to use two batteries to make the motor spin faster! Here is the motor circuit with two batteries: I needed to use some tape to hold the connections in place. You will need to cut a disk from some...
