This is a video of a poincare section of the lorenz attractor with the section plane moving between z=4 to z=78. For laymen out there, basically I did a cat-scan of the Lorenz attractor along the z axis. The section algorithms very simplistic but still works pretty well. If you want to know what the lorenz attractor looks like, check out this link: http://en.wikipedia.org/wiki/Lorenz_attractor
In a simulation, the time step between states itself can have a big affect on the system's behaviour. This video shows a theta/omega stroboscopic plot of a forced/damned pendulum in a runge-kutta level 4 solver. The initial state and parameters are not changed, but the time step is slowly increased. You can plainly see what the effect of a large time step is on the system.
This is a structure I found while play with John Conway's game-of-life in the fall of 2008. Recently our introductory CS class had to build the game of life as an assignment, so I've been using this structure to test their implementations. I've never seen it before and should I be the first to find the structure I would like it to be dubbed the 'Cheeseman Glider Bomb'. Hope you enjoy the video!
This is an animated plot of the Lorenz system using an initial condition of <0.1,0.1,0.1>, sigma value of 16, beta value of 4 and a varying Rho between 0 and 100. This was made using an adaptive-time step RK4 solver, gnuplot, mencoder and BASH.
Many Zune users are now able to sync podcasts to their Zune much as iPod's have been able to for a few years. In particular, video podcasts are just as accessible but have a slight downside to them which results in a bunch of space being taken up on your hard drive. In this video I will show you why this happens and how to alleviate the problem. Hope you enjoy the video!
This is a follow up to a 38x run I did a few days ago. I borrowed a route found by PinkSadist on Youtube and my original 38x route to form a route which goes around the entirety of Paradise City for a literal boosting around the world run. I got 55.9 million points on this run with a 67x boost chain which I think is a record for a no-glitch boost run. Take a look and enjoy!
A time-lapse of clouds forming over the flatirons in Boulder, CO as viewed from my apartment. Reminded me of boiling water. This is my first time-lapse video using my ghetto time lapse setup I made from an old web-cam and some Tupperware. I'll post how I made the setup as well as links to the scripts I used in the near future.
This is a video of my $30 backyard foundry. I made the furnace from an unused paint can by cutting a hole in the top and one in the bottom on the side. I made the crucible from a 2"x6" steel pipe nipple and 2" cap. The whole thing is fueled with charcoal and is stoked by an air compressor. This is the 3rd time I've used this paint can and it is as strong as it was the first time. It got so hot the infrared filter on my CVS DV cam showed the red region as purple and flooded the background in a green tint. If you look carefully you can watch a strip of aluminum ducting disappear under its own weight. DON'T TRY THIS AT HOME!!!
