RADIO PROJECT PRESENTATION Aidan Albert and Selasie Smith
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.
