Summary

The lesson aims to introduce students to Reusing and Recycling of waste in creating their own products or toys in particular. The lesson will also introduce kids to electronic devices and circuits and modern joining methods. Mechanical transmissions will also be introduced to learners.

What You'll Need

Glue Gun

Motors

Card Board/ Cartons

Battery Holder

Battery

Plastic Bottles

Plastic Bottle Tops

Marker Pens

Switch

Wires

Vinyl sheet(optional)

The Instructions

Cutting and Cleaning Collected Plastic Bottles

Clean bottles Mark Bottles Cut Bottles into the desired shape

Clean the bottles using detergent as required thoroughly and let them dry

 

Mark out half the bottle round to indicate the designated cutting area

 

Cut the bottle using a scissors

 

Cut the top of the bottle top into an irregular shape and create a hole in the middle

 

Make a hole on the side of the bottom half for placing the switch and passage of wires

Electrical circuit

Creating the Electrical circuit

On a piece of paper draw the circuit of how the battery will be connected to the switch and the motor

 

Identify the color code of wires and the terminals of batteries and electrical devices i.e. the motor

 

Test the motor by connecting it to the battery

 

Connect the positive side of the battery to one side of the switch and solder it

 

Connect one side of the switch to the positive side of the motor and solder it

 

Connect the neutral side of the battery to the neutral side of the motor

 

 

Assembly

Assembling the Buzzer Assembling the Draw Bot

Place the irregular shaped bottle top on the shaft of the motor and glue it, this now forms the buzzer. Test it and see if it vibrates by placing the batteries in the battery holder

 

Pass the wires leading to the motor from the top and place the motor on the side of the open bottom half of the bottle

 

Glue it using a Glue Gun

 

Place the Battery holder on the top of the bottom half placed upside down and glue it

 

Place the switch on the side and reinforce it using super glue

 

Place three markers at a proportional equal distance to each other around the bottle and tape them round, remove the tops and test the draw bot

Vinyl Cutting Options

Trace an image on paper 2D transfer Vinyl Cutting and Transfer

Draw an image on paper of any sticker after identifying the dimensions of the draw bot

 

Take a picture or scan the drawing

 

Convert it into vector form using a CAD software

 

Print the vector using a vinyl cutter

 

Transfer the sticker
