Laboratory activities are important in engineering courses for several reasons. They provide hands-on experience to help students gain a deeper understanding of engineering principles and concepts; challenge students to think critically, identify issues, and develop solutions; develop practical skills, such as using specialized equipment, conducting experiments, and analyzing data; bridge the gap between theory and practice, promote collaboration and communication among students and provide the opportunity to experiment with ideas and test new technologies. Developing custom-developed lab modules and test equipment tailored to suit specific educational needs are often more cost-effective in the long run and their flexibility allows for the creation of experiments and tests that align with specific learning objectives or research goals. This paper describes the development of a couple of simple experimental test beds that were used in the undergraduate engineering courses. The experimental modules include
(1) A torsion testing apparatus using a load cell and an Arduino microcontroller.
(2) A friction measurement apparatus based on block sliding down an inclined slope but with the ability to measure time and acceleration using optical sensors, accelerometer and an Arduino.
(3) An energy conversion visualization device based on a collar sliding down a bar and impacting a spring.
(4) A bending moment, shear force demonstration device in simply supported and cantilever beams.
(5) Some simple demonstration modules to display gear design, crystalline structures.
