Automatic school bell / Muhammad Qusyairi Haikal Ab Halim, Muhammad Hafizul Abdullah and Nik Muhamad Azmi Ismail
No full textThis paper presents the project and development of a prototype Automatic School Bell. Everything should be performed in time & accurately. Nowadays most school bells are still manually operated. There is also a big question of accuracy and the necessity of manpower. Hence, this project is conceived to improve the school bell accuracy, by making an automatic school bell system. In this project, an AT89S52 microcontroller-based automatic school bell is designed. This circuit uses a programmed microcontroller chip to schedule the school teaching and break periods so that at the start, recess and end for class period, a bell is automatically rang. The bell is designed with AT89S52 microcontroller based technology to get best reliability and maintenance free life. This project finds a considerable use at primary and secondary schools. The benefit here is that the bell rings at the start of each period without any human involvement to a great level of accuracy

The solar charging backpack
No full textAll undergraduate business students in the Marketing program (BA270) at Universiti Teknologi MARA (UiTM) must undertake the subject Innovation and New Product Planning (MKT523). Students, trekkers, and people in off-grid locations increasingly require renewable energy sources as they rely more on portable electronic gadgets such as smartphones and tablets. Traditional charging methods are ineffective in such areas due to the lack of reliable electricity sources. We recommend the Solar Backpack as a revolutionary, multicomponent solution that offers clean, portable energy while promoting sustainable living practices. The Solar Backpack features thin, foldable solar panels that harvest solar power and convert it into electric energy, which is stored in an onboard rechargeable battery. Built-in USB ports allow users to recharge their electronic devices, while LED indicators display power status during charging. The backpack is made from recycled, durable materials to create a waterproof product suitable for outdoor activities and environments. The Solar Backpack includes all the necessary features to serve as an outstanding choice for individuals who care about the environment and require mobile power and portable storage. The Solar Backpack represents modern green technology advancement through its ability to replace traditional energy sources with renewable power. Both functionally and environmentally beneficial, it is a product well worth investing in to promote sustainable innovation
