Side projects

Here you can find some projects that I developed for fun or for teaching.

Double Pendulum


Picture of the chaotic trajectory of a double pendulum. The photograph has been taken with a digital camera in long exposure mode. A similar picture has been published in the FotCiencia 2008 catalog. Pictures of the chaotic trajectory of a double pendulum. The photograph was made with a digital camera in long exposure mode.
The double pendulum is a very simple mechanical system that behave in a fascinating way. It consists in two articulated rods that are linked together. Each one can rotate freely on its axis.

Double Pendulum


If we stick a little laser led on the end of the lower rod, we can capture its motion with a camera. Results are beautiful:





Cycloids and bridges



As you ride your bicycle, without knowing you are drawing beautiful curves called cycloids. We took this picture with my collegues Alvar Daza and Rubén Capeans in Madrid near the bridge of Toledo. We attached two led flashlight on the wheels and just ride the bike while the camera was capturing the movement.



Physics with Javascript



This is a collection of javascript application for undergraduate students. They are intended to work on any device, you just need a modern browser with javascript enabled.
Up to now we have two examples programmed:
  1. Simulation of the inclined plane
  2. Simulation of the thrust law
These apps have been programmed by Alvaro Aranda Jimenéz as his degree final project under my direction.

Music

Learn drums with Random Grooves

If you are interested in music notation, I develloped a web page where you can generate the rhythms randomly. This is an open source project that can downloaded here.



The Chestnut Café

I play drum on my spare time, you can listen to me playing with The Chestnut Café on Bandcamp

Conejo Taladro

Another musical project: Conejo Taladro
