I posted a video on YouTube briefly explaining the basics of interfacing MatLab and AutoCAD for my project.  I will post all videos here as well.

Lost in Stupid Parentheses

Posted by Eamon Kelly on August 5, 2010 at 1:26 PM Comments comments (4)

So lately I've been working in AutoCAD and have starting learning both it and the programming language it uses, AutoLISP.  First, I'll clarify the title of this post by explaining a little bit about LISP.  LISP actually stands for LISt Processing becuase it uses lists as a data structure.  It has been dubbed "lost in stupid parentheses" because everything needs to be enclosed in parentheses.  For example, to add 1 and 1, you would write (+ 1 1).  You'll notice the oth...

More MatLab

Posted by Eamon Kelly on July 14, 2010 at 7:50 PM Comments comments (1)

Sorry that it's been so long, but I have gotten some things done with my code.  The issue with updating about the code is that a lot of the time I spend on it is error-checking, and ultimately the work done is figuring out a robust format, something that doesn't show in graphs.  Despite this, what I have now is a first drop and a hump, and the plan is to use this to figure out functions that find velocity, force felt by passengers, and force felt by track.  After that, I will g...

MatLab Mania

So I spent a few hours today on my MatLab Layout code.  Right now I've got two separate programs, a courseline code and a code for a spine, two rails, and a heartline.  The second of the two is obviously significantly more complicated, but I've made it easier by doing the courseline code first.  Here is an example of the courseline code:

Sorry about the size, but it gets ugly if ...

My Design Project - An Introduction

Posted by Eamon Kelly on March 23, 2010 at 11:32 PM Comments comments (0)

So, I am going to explain here what I hope to accomplish with my design project. This idea has been sort of floating around in my head for a while, after Dan from TPEG (Theme Park Engineering Group) told me about his idea to link up 3Ds Max and Excel to develop a process with which to design roller coasters. We thought about offering this project up to the group, but after consideration we thought it'd be too technical for underclassmen to get heavily involved in,and we were afraid that t...

Project Altius - The Pneumatic Launch Tower

Posted by Eamon Kelly on March 21, 2010 at 6:51 PM Comments comments (7)

I'd like to start my blog off by explaining a little bit about the group from Ohio State that helped me boost my drive to get into the industry.  Our group is dedicated to advancing student - professional relationships in the amusement industry, with a focus on the design/engineering side of the industry.  Our goal is to help students develop skills that manufacturers look for in potential employees.  At the same time, we look to harbour interest in the sciences and engineering...
