For my Electrical Engineering senior design project our subteam was tasked with transmitting digital data from a microcontroller to a remote location for analysis. The data being transmitted is filtered EKG (Heart Beat) data from a microcontroller connected via contactless sensors to a marathon runner. Cardiac arrest can occur when running long distances and the idea is to prevent this from occurring by monitoring for irregular heart beats.

Previous work used commercial off the shelf blue tooth communication chips, but were limited to short transmission distances. Our group (Mohammed Alsadah and Me) decided to perform Binary Frequency Shift Keying over FM using TTL level serial data from the microcontroller located on the runner's shirt. For FM reception we took advantage of the RTL2832U usb chip that can be used as a general software defined radio receiver. Note: This was a single semester project, for the first semester we did a EEG controlled (brain wave) robotic hand, but this one is cooler/more EE related imho.

For my BSCE senior design project our team was tasked with determining the location of robots using the school's wifi network and to have the robots meet when given a command to do so. We were provided four acroname garcia robots which all contain a "gumstix" embedded computer on a chip that runs linux complete with a wifi expansion module for connectivity.

After reading various graduate thesis papers about wifi localization we decided to use what is known as the fingerprinting method. The idea is that you create a database of wireless signal strength readings at various reference points and compare the current location's signal to the database. The "closest" point in terms of signal distance is considered the correct location.

In order to accomplish this, we created various tools to view database information, visualize signal information, etc in addition to the code required for localization and meeting.

altEngine2 is the current version of my cross platform 3d engine that I work on whenever I have long periods of free time. It makes use of q3 formatted bsp maps. I'll try to get some better videos as these two were just really for md5 animation more so than demonstrating everything

• Phong Shading / Lighting

• Collision Detection (That actually works good!)

• Rigid Body dynamics system

• Finite State Machine Based Menu System

• UDP based networking

• Bezier Curve Support

• OpenGL 3.0 support

• DirectX 9 support

Wrote this for a compilers course. It makes use of flex for parsing the input program into tokens and bison to perform the shift reduction of grammars. What did I do you ask? Well I made everything that flex/bison needed to work and wrote the code generation code. This was done in three weekends, the assembly generated is intel style assembly (AT&T style assembly can rot and die) The gnu assembler can assemble intel style x86 assembly easily with a few flags. So the final output can and does work on both windows and linux. The babel language was created by Professor Sweeny, it's basic language, but has all the requirements (loops, if statments, functions, recursion etc)

I really fought the idea of jumping to the end of a function to allocate temporary storage stack space and then jmping back, which is inefficient and therefore morally wrong for me to do as a programmer. (impossible to avoid this with single pass compilation) But I probably should of done it that way anyway as it gets complicated if you dont. I stored all temps on the stack. If anything this should serve as a quick example of how to use flex and bison. [Professor is a linux guy, so I used bzip2]

These are projects from an EE digital logic project course. The code should all compile and work in Xilinx and run on a spartan 3e board, but I'm not sure if these are the latest versions we used as I pulled them out of old emails. Mainly have these here in case I want to use the spartan board I bought again.

WebGrade is a university course management system which was a team project for a Fundamentals of Software Engineering course. I was the team leader of a group of three other students and also acted as lead developer. WebGrade allows an administrator or student to login to manage courses or view grades respectively. It is xhtml strict compliant and makes use of content / presentation division via cascading style sheets. Download it's source code below, username and password is root.

altEngine is a first version of my engine. It runs on windows and X windowing systems. (Runs fine on Linux and Mac OSX with X Window extensions installed.) I like computer graphics and hope to add just about everything to this eventually.

Screenshots of q3tourney2 "The Proving Grounds" being rendered. Textures are missing because I didnt go through the trouble of extracting them. It is loading a bsp file directly from the game and performing the pvs calculations. The boxes are bsp leaves.

Clipmon is a LCD clipboard monitor for the Logitech G15 Keyboard. It is written in C and makes use of the Windows API and low level logitech lcd sdk (Logitech later released a high level C++ API.) Source code is included with the binaries, I had to write my own word wrapping code because of difficulties using a higher level winapi text function and took a different (ie: weird) approach with exception handling. I wrote this thing in roughly 6 hours and like using it on occasion.

Like clipMon, ircMon is a Internet Relay Chat monitor for the Logitech G15 Keyboard. It is written in C and makes use of the Windows API, Winsock, and the same low level logitech lcd sdk. Source is not included as it isnt pretty and the irc protocol parser needs work. (IE: It will crash on you.) It worked well enough for me to lose interest in it. -- Added the source code, cause why not, I should fix it one day

Sealstats generates player rankings and stores statistical data from the Quake3 modification Navy Seals. Based on existing source code given to me by 'LostCause' who created the stats program for Urban Terror, another quake3 modification. I ported the code to work for navy seals and modified/extended existing functionality. A perl script parses the game log file in order to calculate statistics and inserts relevant data into a mysql database via the perl DBD module. PHP is then used to read from the database and display the statistical information. All of which happens in real-time as players play the game.

Upon asking for a logfile to help test the code, the developers of the mod took interest in the program and made it an official part of the navy seals modification. I delivered what I had and they took control of it from there. Images and html code were developed by democritis and other coding work was done by defcon-X.

ns_dam is a map for the quake 3 modification navy seals that I made and never released. The files are too large to upload here, (now uploaded as of July 2016) but it is neat and shows some of my more artistic side. (or lack thereof) It has quake 3 team arena style terrain, terragen skybox, and just about every neat feature possible with q3map2 compiler. I did a quick compile of the map a looong time ago so the lighting isnt as perfect as it can be and the screenshots were taken quickly with texture settings set crappily. (mipmap nearest / picmip 1) Doing a good light compile can take days and odd lighting in places can make you have to restart the whole process. (While hoping the small changes you make to fix one thing doesnt break another.)

q3f_military ~ 2001

Quake 3 Map.

This is that "other map" that I was referring to, went ahead and bsp'ed it and packed it up nicely, intended for the quake 3 team fortress mod, q3f, run it with /devmap q3f_military

I'm going to start writing tutorial like papers mainly as specifications for my own work with hopes that someone may be able to find something useful in my horrible, horrible writing. Links will work when I feel that the papers are developed enough for publication. -- Sorry for taking so long, I wrote most of these papers over the summer, but lost them all when my motherboard died. I'll silently improve these over time.
