DESIGN STUDIO ACTIVITIES DURING INDUSTRIAL PRACTICAL TRAINING

DESIGN STUDIO ACTIVITIES DURING INDUSTRIAL PRACTICAL TRAINING

Dogar, Arslan A. September 28th 2020 

The Industrial Practical Training (IPT) began with orientation of the Design Studio at Dar-es Salaam Institute of Technology. It began with a fun and creative activity of building a tower out of pieces of wires which was aimed at estimating the skill and creativity level. This activity was followed by a brief introduction of the activities that will be carried out during the entire IPT period which include laser cutting, 3D printing, Arduino programming, diagnosis of various equipment, visits to various health institutions and other possible tasks. 

The following day, an introduction to laser cutting was conducted which included the safest and most reliable procedure to operate the laser cutting machine. We were then assigned to carve  pentomino of our choice using the laser cutting machine.  A creative activity was  assigned, this was to create a box or a holder of any equipment or device present in the DIT Design Studio by applying the skill of laser cutting. 

Laser cutting was preceded by 3D printing. This is basically an

additive method of fabrication which involves creating a 

 

3D model of the object to be printed and then using various

 

intermediate software to generate g-codes that are used for

printing the object in the 3D printer. We were first taught  a

sequential approach to efficiently operate the 3D printer and  

then given an assignment to create a bolt  

head that fit the provided spanner size and create an  

earphone holder of our choice. The completed work was then  presented by each individual to explain design criteria and other related aspects of each earphone holder design.

The most dominant activity during the second week of IPT was Arduino programming. Arduino is basically an open source microcontroller which uses the programming codes uploaded into it to operate various functions of sensing from input devices such as sensors and controlling the  output devices accordingly such as servo motors. After the theoretical approach, the first practical activity was to control the LED bulb and perform its various output functions. After a brief introduction to the wide variety of sensors available for Arduino, a sensor had to be selected by each individual and a mini project was assigned to control the glow of the LED bulb using the selected sensor. Each individual had to present on their mini project and explain the function, design criteria and all other aspects related to the design. 

My choice was the flame sensor. The aim was to create a model of a fire detection and control system so I decided to put additional output devices. In addition to the LED bulb to simulate it as a fire indicator, a buzzer was added to simulate the fire alarm. Furthermore, a servo motor was added to simulate the water pump that would supply water to take the fire out.
