This is a simple project to demonstrate the USB custom hardware interfacing with Unity3D game engine on top of Microsoft Windows operating system(s). The custom hardware unit used in this demo is build around Microchip’s PIC18F2550 MCU. This custom USB controller consists with 4 push buttons and linear potentiometer. In supplied demo user needs to control aircraft with those buttons and potentiometer. According to the game logic 4 buttons are used to control the flying direction and flying angle of the aircraft and potentiometer is used to control the speed of the aircraft. System's host environment consists with 2 main applications such as Session Controller and Unity3D game . Session Controller is responsible for USB communication and data conversions. It’s a native application written using Delphi and it gets started with Unity game project. Communication between Session controller and Unity game project is happening through OS level shared memory location. ...

LEDShoot is a simple electronic shooting game which we developed in a year end vacation period. This is a single player electronic game with following game play logic: There are two fighting groups are exists in this game world. RED group is an enemy group and GREEN s are friendly parties. Player’s job is to shoot the RED group(s) when they appear on the stage. Player gets limited time to shoot and misfires are treated as negative points. When player get 100 points game get end with winning message. This electronic game system is mainly based on ATmega32 MCU and firmware is developed using GCC C (with Atmel Studio 6.0). This system is design to work with 5V - 1.5A power supply unit. We developed this system as a hobby project and we construct it on a couple of breadboards, at the moment we don’t have any PCB design for this project. When assembling the circuit make sure to use some heavy-duty push button for ( SL2 ) control key. For ( SL1 ) use 8 Ω - 1W (60mm) sp...

Sudoku is one of my favorite games and in this project we developed small computer program to play and solve Sudoku puzzles in Microsoft Windows operating systems. Like all of my other computer programs this project is also hosted in sourceforge.net with open source – free software license (Under the terms and conditions of GNU General Public License Version 3 ). This project is developed using Borland C++ and it had following general features, Sudoku Game Panel with multiple user profiles Support custom board styles Auto-play options for all the predefine and user specified puzzles Minimize to tray option Three game play levels (as easy, intermediate and hard) Easy to add any number of custom puzzles Latest version of Mini Sudoku is available to download at minisudoku.sourceforge.net and at Mini Sudoku Ohloh project page . To modify this project user need to use Borland C++Builder 6, NSIS (Nullsoft Scriptable Installer) and Adobe Photoshop (or any other image editor which is capabl...
