The goal is to create an efficient, user-friendly, and interactive tool that strengthens the vital connection between parents and teachers in supporting students' educational journeys.

A crucible furnace is an equipment used in the foundry workshop or industry for melting metals for casting operations. They are the oldest type of melting furnaces used for melting and holding small batches of non-ferrous alloys for which a refractory crucible filled with metal is heated through the crucible wall. This paper focuses on the development of a 38-kilogram capacity LPG butane gas-fired crucible furnace used to melt aluminium metal. Drawings were produced to aid the fabrication of the furnace using a mild steel sheet while the other components needed for the fabrication were selected based on functionality, durability, availability of local materials and cost. The test was carried out on the furnace to evaluate the performance and the results obtained showed that it took the furnace 24minutes to completely melt 38kg of aluminum scrap between 630 0C to 700 0C. The heating rate is 56.110 C/min, melting rate of 1.58kg/min and a 39.6% maximum efficiency, which is quite impressive when compared with the conventional crucible furnace.

This project aimed to design and implement UnibenEngVault, a web-based platform created to provide engineering students of the University of Benin with centralized and convenient access to academic resources such as lecture notes, past questions, and tutorial materials. The initiative was motivated by the persistent difficulty students face in sourcing relevant study materials dueto the lack of a unified and structured digital repository within the Faculty of Engineering. The development followed a structured methodology consisting of project planning and approval, problem analysis, system design, development, and deployment. The UI/UX design was created using Figma to ensure an intuitive and visually appealing interface. The frontend was developed with ReactJS, while the backend was implemented using Python (Flask) and PostgreSQL for database management. AWS S3 was utilized for cloud storage, and deployment was achieved through Docker, GitHub Actions (CI/CD), and DigitalOcean Droplets to ensure scalability and reliability. Security measures such as session authentication, CORS configuration, and bcrypt password hashing were implemented, alongside thorough unit, integration, and user testing. The final outcome is a secure, functional, and user-friendly platform that enables students to easily access department- and level-specific academic materials. UnibenEngVault enhances academic collaboration, improves resource accessibility, and provides a sustainable technological solution to the long-standing challenge of academic material distribution within the Faculty of Engineering

This project focuses on the design and fabrication of a hybrid (solar–electric) dryer for agricultural materials. The aim is to develop a low-cost and efficient drying system that utilizes both solar and electrical energy to ensure continuous operation under varying weather conditions. The dryer was designed with major components, including a solar collector, drying chamber, heating element, and forced draft fan powered by both photovoltaic and electrical sources. Locally available materials such as sheet metal, glass, insulation, and mild steel were used in the fabrication process to promote affordability and sustainability. Performance tests were carried out using cassava chips as the sample material, and relevant parameters such as temperature variation, drying time, and moisture reduction were recorded. Results showed that the hybrid dryer achieved faster and more uniform drying compared to traditional open-sun drying. The system proved reliable, environmentally friendly, and capable of maintaining operation during periods of low sunlight. This innovation demonstrates a practical approach to reducing post- harvest losses and improving the preservation of agricultural produce in regions with inconsistent power supply

The comprehensive study of high-frequency transmission lines, including stripline, microstripline, differential microstrip lines and differential straplines configuration is critical for advanced RF and microwave engineering education. Fundamentals of some transmission line phenomenon such as impedance matching, reflection coefficient and the effect of open and short circuits, relies greatly on practical hands-on experience alongside theoretical tools like the Smith chart. Furthermore, many academic institutions face challenges in providing laboratory systems that accurately represent high-frequency transmission line structures on common PCB substrates such as FR4. The absence of versatile and cost-effective experimental circuits limits students’ opportunities to explore and solve real-world transmission line problems, thereby hindering the development of essential engineering skills. This project aims to develop an integrated high-frequency transmission line experimentation systems for university laboratories, incorporating stripline, microstripline, differential microstriplines and differential striplines configuration on FR4 substrates. The system will facilitate direct measurement and analysis of transmission line behavior, enabling students to visualize various experiments, and investigate the proposed applications (e.g. open and short circuit effects, s-parameters,
transmission line as a filter etc.) within a controlled environment.
By linking theoretical concepts with practical experiments, specifically through the application of Smith chart and transmission line theory, this system will enhance RF engineering education, equipping students with the competence needed to address modern communication system challenges effectively

In order to fuse two metal components, electric arc welding uses electrical heat to cause melting, which, when cooled, forms a solid connection. In order to protect the molten metal from exposure to the atmosphere and stop chemical reactions, slag is injected throughout this operation. A power source that creates an electric arc between the metal material and the electrode to be fused is necessary for this process. Both consumable and non-consumable electrodes, as well as alternating or direct current, are used by welders. An electrode is a conductor that creates the heat required for melting and fusing by sending electric current to the metal to be welded. Whether an electrode is consumable or non- consumable depends on the specific arc welding process being used. The electrical energy needed for the arc welding process may be obtained from a variety of power source methods. Constant voltage and constant current power sources are the most common varieties.
