DESIGNING OF ULTRASONIC SENSOR AND INFRARED SENSOR (IR) Ultrasonic sensor An ultrasonic sensor is a sensor that measures the distance to an object using ultrasonic sound waves. It uses a transducer to send and receive ultrasonic pulses that relay back information about an object’s proximity. How Ultrasonic Sensors Work Ultrasonic sensors work by sending out a sound wave at a frequency above the range of human hearing. The transducer of the sensor acts as a microphone to receive and send the ultrasonic sound. Our ultrasonic sensors, like many others, use a single transducer to send a pulse and to receive the echo. The sensor determines the distance to a target by measuring time lapses between the sending and receiving of the ultrasonic pulse….

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…
It’s all about learning
It’s all about learning!! The most interesting part of our lives everyday is learning,what I mean is never skip a day without learning a new thing. Try to add some new products to your brain shelves. To keep a long story short and precise I am going to give you a quick glance into what has happened and has been happening in the DIT Design Studio for the last two weeks (from the 2nd to 13th of AUGUST) during the Lemelson Engineering Internship period. Well, the first lesson was about Design Thinking and then my question to you is have you ever designed anything in your life, career, job or anywhere? If yes then kudos! And if not this is…
First is always the best!!
LEMELSON INTERNSHIP 1st WEEK!! The Lemelson Internship started with orientation in the Design Studio at Dar-es-Salaam Institute of Technology which was conducted by Joel, one of the teaching assistants. It began with a fun and creative activity of building a tower out of pieces of wire. This was aimed at implementing the team work spirit, working under pressure (since the provided time for completion was reduced purposely), optimum utilization of resources and so many other good lessons. This activity was followed by a brief introduction to the activities that will be carried out during the entire IPT period which include laser cutting, 3D printing, Arduino programming, visits to various health institutions and other possible tasks. The next day, introduction to…
LEMELSON INTERNSHIP WEEK 1
BENJAMIN LEMBARO I have just completed my first week as an intern under the Lemelson Foundation. It has been a very busy week accompanied with so many activities that were aimed at sharpening our skills. On the first day of the internship we were given a general overview, the objectives of the internship as well as what is expected of us by the end of this program. On the first day of the skills week, we started with Computer Aided Drawing (CAD). We used the Fusion 360 application to develop different 3D drawings which is an essential skill in the presentation of our ideas into drawings. We learnt as well how to get 2D projections of different views from 3D…
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...
BUBBLE CPAP MACHINE (v.2)
Introduction Acute respiratory infections are the leading cause of global child mortality. 20–38% of deaths in the first 48 hours of life are attributed to respiratory failure. Moreover, complications associated with premature birth, often related to breathing problems, are responsible for an additional 30% of neonatal mortality. In the developed world, babies with respiratory distress syndrome (RDS) receive mechanical ventilator support, but these lifesaving technologies are too expensive and resource-intensive for most of the developing world. As a result, RDS remains one of the most common causes of neonatal deaths in the developing world. There is an important need for new, cost-effective technologies to treat infants and small children with respiratory distress. The need is particularly acute on the African...
Bubble CPAP Machine v2.0
The author cutting some wood for his prototype Introduction Acute respiratory infections are the leading cause of global child mortality. 20–38% of deaths in the first 48 hours of life are attributed to respiratory failure. Moreover, complications associated with premature birth, often related to breathing problems, are responsible for an additional 30% of neonatal mortality. In the developed world, bubble Continuous Positive Airway Pressure (CPAP) is a gentle and effective tool to manage babies in respiratory distress. Hospitals use tubing, wall air, and oxygen to set up bubble CPAP at the bedside. Pressure is safely and simply regulated by submerging the end of the tubing in a bottle of water. The depth of the tube in the water determines the...
CLASSES- Electronic Design Workshop
Mr. Urassa at his desk Hello, I’m Philimon S. Urassa. I am a Telecommunications and Electronics engineer working at the Dar Es Salaam Institute of Technology as a tutorial assistant where I teach a basic electronics and electronics design workshop to Ordinary Diploma students. In the Design Studio, my students got the opportunity to design and implement simple electronics projects that help to solve real life problems and challenges. Through the availability of tools and machinery in the Design Studio, my students are able to come up with simple design and good looking products that can be applied in society for the sake of coming up with a solution. During the design learning process students were exposed to multiple rapid...
