This research analyzes the parameters affecting the penetrating resistance of shells on the armor surface by the finite element method. In this study the results were compared with real bulletproof armor firing tests and finite element simulations. modeling of bulletproof and bulletproof armor using Solid Works program. Creating and simulating armor firing pattern using ANSYS Explicit Dynamic program. damage test is based on National Institute of Justice (NIJ) level 3 standards with bullets the material of the ammunition is 7.62 mm tungsten carbide (WC). there are two types of bulletproof armor used in this simulation 1) SKD11 2) Aluminum AL7075. The simulations is into 1 category Simulation of stacked armor plates. The sizes of the armor plates are 6 8 and 10 mm and the angles of firing of bulletproof armor are 0 30 and 45 degrees. result of this simulation armor thickness and firing angle are factors of penetration resistance.

The objective of this study was implementation of microcontroller to construct Appl to control the operation of the Dog food exchange machine using plastic bottles system. To study an operation control of microcontroller system operation and the to create construction of a Dog food exchange machine using plastic bottles. The component of Dog food exchange machine using plastic bottles are divided into 3 parts: 1) parts of detecting plastic bottles sensor 2) part of the motor control 3) part of the vending machine. Results of the study of Dog food exchange machine using plastic bottles. used in 2 ways: 1) plastic bottle vending 2) coin vending for 10 baht. When the total number of bottles is set at 15 bottles the plastic bottle vending machine will not work until the Reset button is pressed. Can still work normally

This project aims to develop RFID reader. With the following scope can scan at least 15 cards save both entry and exit data display Welcome on the screen and add or reduce codes by yourself The test results show that the RFID scanner can scan both key cards and manually scan both in and out. The screen also shows Welcome when someone enters and shows thank you when someone shows that the developed scanner can be applied really slowly

This project was made in topic “The Development of Internet Management System in The Form of Programming Via API Internet : A Case Study of BanTiLiaPa Border Patrol Police School” aims to develop the internet system management to be efficient and facilitate the internet system management easier. This system is working through Mikrotik internet network that developed by using PHP to design website to improve the users. For using Bootrap for to design website as well as design the system by using Atom program to edit coding in the internet system management website page. The study found that This system can work to cover the educational objectives that have been laid. Can be used to develop the internet management system very well And also helps to facilitate the management of the internet system

The purpose of this project is to construct a horizontal electric train controlled by the Arduino. For the cost that is cheaper than the market and users can be self - reliant in daily life In which the car size is equal to the electric train that is sold in the general market. The organizers can write an arduino program to control the movement of the car from the joystick lever. The built weighing 25 kilograms is powered by a 12 volt battery that provides power to the circuit to control the direction of the car. The car can support a maximum weight of 100 kilograms and can be adjusted to more than 160 degrees. Experimental results Found that the operation of the electric train is adjustable controlled by Arduino Able to work according to objectives. This Arduino - style electric train can adjust the sitting position to your desired position. The control to change direction can be forced forward backward left right turn from the lever from the joystick as needed. As for the road characteristics it can be used as smooth and sloping roads.
