Item Open AccessDesign and Construction of an Electronic Mosquito Repellant.(Kabale University, 2022) Kwesiga, IsaacThis work is titled design and construction of an electronic mosquito repellant device Mosquito repellants like coils, mats, liquid vaporizers and creams are often used at various places. However, they are prone to be fatal and can cause harm to human beings. For instance, mosquito repellant creams and creams can cause adverse effects on the skin like allergic reactions. Coils, mats can produce toxic fumes when heated and cause breathing trouble whereas liquid vaporizers can also produce fumes when heated. For efficient result without any side effects, the most optimum solution is constructing a simple electronic device with minimal components which can produce output so as to repel the mosquitoes. The aim of this work is to design an a simple electronic device which can produce ultrasound in the frequency range of 20kHz to 38kHz, which can scare away mosquitoes.

Item Open AccessDesign and Construction on A simple Magnifying Glass Using Recycled Bottles.(Kabale University, 2022) Mbonyimukiza, AndrewHuman eyes have limitations of visibility because not all objects in focus give brighter and sharper images needed to access quality. Some objects appear smaller. In order to view smaller objects, a magnifying glass is used to make the objects bigger to the eye hence it can reduce the cost of purchasing spectacles. Therefore, the project is about design and construction of a simple magnifying glass using recycled bottles (relatively equal disc cuttings), glue, syringe, a sharp knife, a pair of scissors, left over part of cello tape or bottle top made hollow and a marker.
