Task 3 Name: Amplifier Set: w3 Due: w13 Weighting: logbook (50%) Courses: cbhh
Prev Task: Laying on of Hands and Hacking the Clock Next Task: Synthesis on a chip
Task Summary All CBHH tasks

While you're investigating your toy you it's useful to be able to use your toy's built-in speaker. (It does have one, doesn't it? Otherwise it wouldn't have an audio element and so wouldn't be suitable for this course.)

You will need:

  • A socket of some description. Most common is mini-jack. It can be stereo, but as the output of your toy is likely to be mono, mono would be better.
  • A cable to connect to whatever you want to connect your socket to. If you've planned this, you might be able to use the cable you produced for task one.
  • A separate speaker or piezo for testing.

  • Make sure you document each step of the process below.
  • Find your toy's speaker. This might be a fully-fledged speaker, or a tiny piezo disc.
  • Test the connection by attaching a separate speaker to the connections to your toy's speaker. Connect from the toy's speaker itself to begin with.
  • When you're sure that the connection works, attach an audio output socket to your toy/device - use a socket that you know works with the speakers you'll be using. Remember sockets can be stereo or mono.
  • Connect this to some speakers with a cable.
  • Check that it works.

  • Document the process with plans, photos and, yes, videos of it and of it working, and include this documentation in your logbooks.

  • Media files
    You must submit media files, such as video, audio or image files, but please ensure that video files are compressed to a reasonable degree. You should never submit dv files, but compress these to mp4. You should submit no file that is greater in size than 25MB/minute.

  • Added value
    By completing the details of the task you will achieve at least a pass mark. By imaginatively and creatively considering how you might implement the task originally you can add value to your submission, and this added value may increase your mark significantly. Even when making videos of short demonstration tasks try to consider musical and performance criteria.

  • Suggested questions to consider answering in your logbook
    1. What is the difference between a standard electrical/physical speaker and a piezo disc? What are their important features and in what circumstances might you use one or the other?


  • Include all these components in one section of your logbook. Include images within the logbook, and any audio or video recordings alongside.

  • Submit your logbook to the i-Centre by 2pm on Tuesday 8th May 2018
