Getting Started

Students must complete this activity before attempting any other activities.

In this tutorial we will guide you through building a basic frame, and show you how to use all the different pieces of equipment.

Electronics Starter Kit

Learn how to motorise your contraption with the EPro8 Electronics Starter Kit.


Comprehensive Electronics Kit

Learn how to use all the equipment in EPro8 Comprehensive Electronics Kit.

Fire Engine

Construct a fire engine and its ladder.

Build a mechanism for raising and lowering the ladder.

Measurement, Leverage, Electronics, Logic.

Burglar Alarm

Build a spring loaded alarm system.

Trigger this when a window is opened or with a trip rope.

Pimp your alarm using laser beams and mirrors.

Pulleys, Mechanisms, Problem Solving, Electronics

Caveman Car

Build a rubber band powered caveman vehicle.

Modify the vehicle to achieve extra speed and distance.

Energy, Measuement, Practical Mathematics
