5.1
Introduction to Project
Your project work is divided into the following 6 stages, and you will be
assessed separately on each of these stages. In addition, on your project
prototype and report.
Figure 5.1: Stages of project work
Your communication skills will be assessed on the basis of your written
report that you will submit on completion of your project. Your written
report must include all the six different stages indicated in figure 5.1.

Project Topics
Choose any one of the problems outlined below, and design, build and
test a circuit that will provide a working solution to the problem described.
Discrete components could be used to implement the design; the circuit
must be initially assembled on the breadboard for the purpose of testing
and then finally soldered on the PCB. Each team shall consist of not more
than three students. Your report must include the following topics:
a. A brief description of project
b. A list of all components used
c. Printouts and/or photos of all inputs, outputs and circuits
d. Printouts of computer simulation results
e. Merits of your design
f. Suggestions on how your design could be improved
1. A power supply is used to convert high voltage AC mains electricity
to a suitable low voltage supply for electronic circuits and other
devices. Part of the design of a power supply is the rectification and
smoothing of voltages. Your task is to design a basic power supply
to convert an AC voltage to a rectified and smoothed DC voltage.
Use a half-wave rectifier and a 12 Vrms AC power supply to provide
the ac voltage. Try different capacitor and load resistance values to
reduce ripple and achieve smooth output.
2. Design and build an analog multi-meter that is used to measure DC
voltage
and
current.
The
meter
should
have
the
following
specifications:
a. Selector

b. Voltage range: 0 – 15 V DC
c. Current range: 0 – 1 mA DC

ATE 1110– Measurements
Use your analog multi-meter to measure voltage and current in different
circuits. Check your results by using a digital multi-meter. compare the
results obtained by using the two multi-meters. Which multi-meter, in
your own opinion, is more accurate? Justify your answer.
