Hi!

I want to share a project that was done some one or two years ago and is opensource (from today it is published). The page of the project is :

http://code.google.com/p/extrae/

The main idea is to make a simple yet functional data logger and very basic analysis tool for education. The PC interface is done in JavaFX (by the moment in spanish but easily understandable, soon in will be translated to english and other languages). The project is now restarted and we hope to get some feedback so we can improve it (if you want to improve it yourself, its opensource so please do so).

Hope you find it useful in some way and you can spread the word so it gets used in the places it was meant to be used: schools.
Cheers!

Maybe you can start with some rationale / design / screenshots / diagrams and what it can do for the average Arduino users?

Sample sketches can do miracles to seduce people

Hi,  I will put some screenshots and some usage videos as soon as I can. Let me explain the project a bit, it is made of a firmware and a PC software. Both downloadable from the link: http://code.google.com/p/extrae/ . The firmware is a sketch for arduino that receives and send data to and from the pc. The host is a JavaFX data visualizer. From the host you can control the timing between measurements in the arduino (for analog meassures), the number of samples, the value and direction of a simple trigger to start taking samples, the interrupts for 4 digital channels (the 2 classical ones and 2 extra ones), etc... the idea is, in short: make an interface so that people can do experiments in physics (and other sciences) that would normally take expensive (or more expensive at least) hardware.
The host software also has a simple option to send the data through networking protocols (it is not very sharp and we hope to make it a lot better soon) so that, for example, when a student measures the rising in temperature of a glass of water being heated, an animation that particles gain movement while this raise in temperature is measured explains that temperature has a connection with change in kinetic energy.
The project itself is a good science project to be shown to student as arduino code is understandable and, if the functionality of different sensors can be explained, the student can also understand the hole process of sampling.
Hope this clarifies the idea a bit so that some people might test it...
cheers!
