Rapid Audio Amplifier Project Kits

• Students have the opportunity to build a small amplifier, which can be incorporated into a variety of product designs, e.g., as an amplifier for a personal CD / MP3 player so that they can share their music with their friends
• The students have a number of design situations to select a starting point from, and they are provided with research topics and background material to help build understanding for their chosen design brief
• The student notes provide material for students to explore how a range of simple amplifier circuits work
• They also include guidance on the design and construction of speakers
• To support students during the construction of the circuit, detailed instructions have been included on how to assemble the amplifier, and how to integrate the circuit into student designs
• In addition, care has been taken, through extensive evaluation of the teaching material and PCB designs in schools, to ensure that the circuits are easy and robust enough for student manufacture
• A detailed set of teacher notes is available which includes suggested lesson plans and mapping to the National Curriculum
• The project notes have been designed for photocopying for class use
  
  Each kit contains the following:
• TBA820M audio amplifier and IC socket
• Resistors, capacitors, and LED
• Switch and connecting jack socket
• Connecting cable
