Design and Construction of Mini-stainless oven with a Two and One Shutdown System
Abstract The aim of this work is to characterize properties and microstructure of stainless steel used as a coating on welding of carbon steel sheets. Two carbon steel plates were set as the metal base and the stainless steel coating was applied on the weld bead. The applied process used was the submerged arc welding (SAW) and tests were carried out for the tensile strength and Vickers hardness, in addition to observation of the microstructure by optical microscopy. The results indicated that...
Design and construction of bio-gas for household use
ABSTRACT: The designed air driven engine is an economic friendly engine which operates with the aid of a compressed air. in principle, an air driven engine uses the expansion of compressed air to drive the pistons of an engine. an bio gas driven engine is a pneumatic actuator that creates useful work by expanding compressed gas. there is no mixing of fuel with gas as there is no combustion. An gas driven engine makes use of compressed gas technology for its operation the compressed air techn...
Design and Construction of Smart Card Security System
ABSTRACT This project shows the construction of a microcontroller based security door using Smart card. It is aimed towards programming the microcontroller to control the Hardware in sliding door. The system consists of a microcontroller 89S52 which Sends a signal to the multiplexers on insertion of the smart card in the card slot. The multiplexers consist of ICS which prompts for a display of the identity of the Card user in the liquid crystal display (LCD). The LCD displays the status of th...
