RADIO PROJECT PRESENTATION

Aidan Albert and Selasie Smith

Objectives

The aim was to produce a mini AM radio using the parts that were supplied

This had to be accompanied by a report (submitted in written/online form) containing the step by step process of the construction of the radio illustrated with photographs

In addition to the AM radio we had to construct a mini amplifier

Preparation:

We started on carrying out research on how AM radios work and how the are constructed

We presented or findings on the Group WIKI so we could return to this at a later date and refer to for the report

GROUP WIKI

Online Report The report will be divided by topics and then

combined together. (aims/objectives/apparatus/procedure/results etc.)

Using the Group Wiki (image seen above) this is where we will publish our report

The benefit of publishing the report here is that we can include images of the production and we both have access to this

Another benefit was that on the Group Wiki this was were we displayed our findings, the research we carried out before beginning the production of the radio

Production:

We were given a mini circuit board with the components of the AM radio.

After that we had to make sure we fitted these in the correct places in the circuit board.

Once these were fitted we soldered them into place.

SOLDERING

Production:

Once we believed that we had completed the first task we carried out a test

It was then we realised that we had soldered some of the components in the wrong place, and had to remove these and start again

INCORRECT PLACING

Production:

Our attempt to rectify the problem caused more damages so we were given a ready made AM radio

DAMAGE CIRCUIT BOARD

Production:

After testing the replacement AM radio we were given we moved on to produce the mini amplifier

Whilst constructing this we took much care as to where we placed the components on the circuit board.

NEW AM RADIO + AMPILIFIER

Results

Once we tested both the amplifier and the AM radio, it gave the sound of a clear radio station with a slight bit of disturbance but still legible.

Evaluation: Throughout this whole project we both

learnt how radios are constructed from the smallest to the biggest of components.

We also learnt how important the placement of components in the circuit board are, as the smallest fault can create massive problems for the radio.

We learnt that there are different types of carrier waves which all range from certain distances.
