Mini+-+Amp+&+Speakers

toc = Introduction = You are going assemble a mini amplifier/speaker kit from **[|KitsRus]** which can be plugged into your MP3 player/iPod to amplify the sound and play it through a pair of small 8v speakers. media type="custom" key="5152579"

= Design Situation = The printed circuit boards, battery and speakers require a suitable casing made of acrylic. This will be designed around a template using Techsoft 2D design software, cut on the laser cutter, and assembled according to your own specifications.

Using Techsoft 2D Designer - there are some **[|video tutorials]** at Top Valley School and Engineering College

= Assembly = The PCB (printed circuit board) needs to be assembled, soldering carefully each of the components into the correct place.

= Design = Design ideas need to be sketched and modelled, before being made into prototypes and then final production. media type="custom" key="722243" = **Evaluation and Modification** = The final step requires us to evaluate the project, a number of points need to be considered
 * The accuracy of our soldering of the PCB and its components.
 * Testing the circuit functions.
 * The shape and size of the casing for the PCB.
 * The shape and size of the casing for the Speakers.
 * Testing the casing:
 * Do all the components fit in?
 * Is the battery easily accessible?
 * Do the speakers stand easily?
 * You will consider any modifications that could be made, drawing and annotating any alterations.

= Knowledge and Understanding = Understanding and expanding your knowledge of electronics will help you with the assembly of your PCB.
 * Being able to recognise components.
 * Understand the function of the main components used in this mini - amp circuit.
 * Understand the design process as it is applied to the design and manufacture of the casing for this project.
 * Expand you understanding of the manufacturing techniques and knowledge of acrylic.
 * Understand how printed circuit boards are manufactured.
