Outside of work, I build things — from Unity game prototypes and Arduino-powered cold frame hinges to electric bikes with custom battery packs. Below is a collection of projects and work I've done over the years.

Solving problems we find interesting, on our own time, for our own reasons.
A gentleman farmer's approach to technology: build it because it's fun, not because it pays.

The goal of this project is to create a powered hinge for a cold frame or green house that automatically opens and closes based on temperature. An arduino was used for the control board to read the temperature sensor and instruct the servo motors when to operate.
Parts Used:
Arduino Wiring Diagram
First prototype
3D Model of version 2

Worlds are generated with multiple zones and levels inside. Each level is created using Cellular Automata techniques to generate the solid parts of the terrain. Levels are currently only rectangular in size, and each level has multiple paths/doors to other levels. These paths are created randomly within a tree like structure.
Level Creation Steps:
To ensure that all doors on the levels are accessible to the player, A Star path finding techniques are used after level boundaries are created and cellular automata logic is run. A Star is run between each pair of doors within a level, with weights on solid cells of the grid being very large, causing the path finding to travel through already opened areas created via the cellular automata. If a door is not accessible the path finding will remove solid cells to ensure accessibility.
Connected Component Labeling was used to ensure that all open/non solid areas of the level are accessible. Each connected open space is checked against its neighbors to ensure it is accessible by the player, path finding is then used to create a path if needed.
Enemy Behavior was created with a design pattern found in the book Programming Game AI by Example. This allowed each enemy to have emergent behavior based on various goals and conditions of the game world. Goals and actions included keeping rooms cleared of enemies, avoiding attacks, seeking out health, etc.

Game concept: Starting with a base mothership that allows the player to create collector ships to collect resources. With these resources, ship attachments can be made including defensive systems, weapons, armor, fuel, batteries, etc. Ships are limited by the power generation, create a challenge to manage building out the ship, traveling to collect resources, firing weapons, and high speed assault maneuvers.

Added Working Turrets that shoot. All entities have health, when they run out of health they are removed from the scene. Sounds are activated when the player or the turret shoots as well as on projectile impact.
July 2012
Added Simple Enemy AI and Zombies
July 2012
Game Test to demonstrate guns and shooting, enemy AI, collision detection, player movement, destructible and solid ground.
June 2012
Updated the level collision detection code to support two images, one image (bottom) that is actually rendered to make up the level, and the second image (top) that tells the collision block creation code what type of collidable object to make. Anything transparent is non-collidable, anything black is solid and can't be destroyed and anything red is collidable and can be destroyed.

So I have been playing around with game development for a while. First I had alot of trouble picking a game engine and a language. For a while, I was doing alot of webdesign with PHP and mySQL, which isn't very similar to game development. Now I am currently working as a J2EE developer (JAVA and JSPs). I first started out playing around with Unity Game Engine which is very nice, but I'm the type of person that likes to know how everything works. Unity does a great job at allowing you to focus on the game and its content rather then the engine and architecture of how the game works. I then decided that I would use jMonkey Engine and create a 3d space shooter type game. This was going well, but I felt I was spending more time tweaking physics settings and 3D modeling then actually coding the game.
Recently I decided I would give Slick2d a try.
I am currently working on multiple aspects of this game, but the initial development was on creating levels. Slick2D supports levels created out of tiles that you can easily create with third party tools, but this only allows for very rigid levels. I decided that I wanted something more flexible. I finally decided that I wanted to be able to import a png image with transparent background. Anything opaque would be mapped as solid for the collision system. Below is the initial result.

I modded halo for PC under the name of Ang88, back when it first came out. I worked by myself for a while, was part of ClanX and then joined =EP and participated in the =EP map team. I created alot of maps, but unfortunately many of the sites are down now that have references to the material and maps I made, also, my harddrive died that had most of the files, so I have very little left of the very interesting work that I did.
One of the maps that was never finished but got alot of fame was the Ndugu map for Halo. I did alot of work on this, and had a great time making it, but sadly it was never finished because my team fell apart.
