FIRST WEEK OF LEMELSON INTERNSHIP 2021

During this week we started by learning Computer Aided Design (CAD) using Fusion 360 Software. Fusion 360 is nice software to get started with CAD because it has a simple and friendly user interface and cloud storage capability for the projects which allows working on different computers. We started drawing basic shapes and specifying basic dimensions as normal Engineering drawings. After we had covered some basics we were given a task to draw 3D shapes and print them using a 3D printer. The figure below is the drawing which I was tasked to draw. The above object was used to certify us on our 3D printers skills. This certification required us to import an STL file from Fusion 360 then…

Keep going!!

KEEP GOING…!!! Maximilian Donath Mkenda. August 16, 2021. Joining the Lemelson Internship is a lot more fun than I thought it would be in the best way possible. So far, I have already gained many skills, and I have learned more about different things used in everyday activities such as laser cutting, 3D printing, soldering, Arduino programming and the diagnosis of various equipment. As for expectations for the rest of my internship, I am thrilled to learn more every day and have been working with very talented people from whom I know I will learn more. This internship has given me even more real-world experience than I had before. It has also given me the chance to learn more about…

Trash-2-Treasure

Thoughtful waste management in makerspaces Waste is an often inevitable by-product of design. The design process taught in the studio encourages student engineers to try out many ideas, iteratively refine existing solutions over time and make many mistakes. These activities lead to the creation of waste in multiple forms – software files, printed paper, soldered boards, 3D printed models, wood, metal and acrylic offcuts – all of which could be destined for the trashcan. The DIT Design Studio has been working to ensure mindful reduction, reuse and recycling of waste created in our space. This blog post will detail some of the ways we have done this. Waste 3D filament Reduce The design studio operates on a finite amount of...

MAKING THE MOST OF IT

Sandra (LEFT) and DIT Design Studio Admin Assistant Aziza (LEFT) My name is Sandra Sommi, I am a third year student studying a Bachelor of Computer Engineering at the Dar es salaam Institute of Technology. My team and I were assigned the task of designing an automatic unmanned robotic system by our instructor, Dr. Simbeye as part of our course - Robotics and Intelligent Systems.  The primary motive behind this project is to design and fabricate an automatic robotic system that will operate automatically without any human intervention. The original idea was to implement an automatic robotic arm that will perform pick and place functionality. But later as a group we came up with the idea that the robotic system...

DEVELOPMENT OF AN AUTONOMOUS MILK VENDING MACHINE

Q: Tell us about yourself. Who are you and what is your background? A: I am Jamal Akida (25), a Muslim graduate of the Dar-Es-Salaam Institute of Technology (DIT). I studied Computer Engineering and graduated in the year of study 2019/2020.I have extremely high attention to detail and love the challenges involved in technology (especially computerized systems) no matter how big or small – I also enjoy working as part of a team. Over the past four years, I have attended Industrial Practical Training (Field student) at different organizations where I used my knowledge to be a part in the design and implement software, hardware systems, and network configurations at the Institute of Judicial Administration (IJA) and TONTAN Technologies. Currently,...

Expansion 3DP – A STUDENT BUILT 3D PRINTER

^Our team and the completed Expansion 3D We are a group of 5 final year Bachelors students in the department of Computer Studies. We are genuinely interested in everything that deals or works with computers, ranging from networking, electronics and software development. During the first semester of the academic year 2020-2021 around mid-December, we decided to build a 3D printer as part of our coursework assessment for a core module named Robotics and intelligent systems. Having no prior experience in building a 3D printer nor a significant knowledge of its operation, we first had to understand how CNC (Computer Numerical Control) laser or plasma cutter worked as a means of building a fundamental background that could ease the understanding and...

Small and Amazing

                               SMALL AND FINAL PROJECT The last week was special for completing our small project and start dealing with final project after the visitation we made at Muhimbili National Hospital(MNH) and Comprehensive Community Based Rehabilitation of Tanzania (CCBRT Hospital). Where we conducted research and investigated different problems and challenges facing the Hospitals. As we observed different problems our task was to work on them and find solution based on either doing maintenance where needed and invading new appropriate technology.                                              SMALL PROJECT From the starting day of our IPT sessions in DIT design studio, I acquired variety of knowledge in different parts like knowledge in Laser Cutting, 3D Printing, Arduino, Research knowledge and other Technological knowledge. Under Supervision and Training from…

Best run starts with a good muscle stretch

  Best run starts with a good muscle stretch – Thomas N. Shetui A week of design thinking – Starting up with a design thinking 101 session trying very deeply to understand how to internalize the problem through empathizing it and evaluating how the problem affects the end users. The procedure required first hand interviews (as a primary source of information) with the targeted end users. The information provided could be used to structure solutions to that problem and later secondary research was done.  With the primary and secondary research commencing on the problem assigned to work on, “How can we encourage hand washing and make it safer” thereafter modified to, “How can we make most DIT students wash their…

Needsfinding and Research: Key components of the design process

FINAL PROJECT Hindu Katowa There is no distance with no end. We are almost done with the internship. We are in 6th week of the internship. Right now we are working on our final projects, in which we are trying to solve challenges in which CCBRT and MUHIMBILI NATIONAL HOSPITAL face.  In our group we are trying to look at how to solve or how to help a person with cardiac arrest with an automatic device and not manually which is the current method used in Tanzania.    This method is not effectively done because cardiac rescue faces fatigue when performing the chest compression so it’s hard for them to perform 100-120 compressions/min.    So the doctors suggested using the automated chest…

Make it work

PROTOTYPING A prototype refers to the preliminary version of a device from which other devices will be developed. It is usually used for testing a concept. This week our group was mainly dealing with finalizing our prototypes which were on the IR-thermometer. The thermometer infers temperature from a portion of the thermal radiation emitted by an object being measured. It is sometimes called a laser thermometer as a laser is used to help aim the thermometer. It works by measuring the temperature of infrared energy which every material or object with a temperature above absolute zero radiates. A lens focuses the infrared radiation onto a detector which in turn converts this energy into an electric signal. After compensating for the ambient…
