Wii remote acceleration plotting

When I first started looking into ways of obtaining acceleration data from a Wii remote, I stumbled upon a Mac application that could plot the acceleration readings from the remote in real time. At the moment I thought it would be very nice if there were something similar for Linux but I could not find such an application.

Xraters is a very simple application that plots the acceleration reading from a Wii remote to the screen in real time. It allows the user to save the data to the disk.

I am using a Wiimote as part of a physics experiment and this application is a striped down version of the software I wrote to control the experiment. Xraters is based on the. Xraters is written in Python taking advantage of the cwiid library.

Wii remote acceleration tracking

I created a very simple application that tracks the position of a Wii remote based on the accelerometer readings and draws it on the screen. I wrote Wiitracker as an demonstration to be used in a series of vocational conferences I will be giving in the recently opened Planetarium of Havana about the uses of sensors in space exploration. Wiitracker is written in Python taking advantage of the cwiid library.

Software defined radio receiver

SDR receiver front panelA Software defined radio (SDR) is a radio communication system where the signal processing is done in the digital domain unlike conventional radios; which are based in a series of analog filter, mixer, modulator and demodulator circuits. This type of systems are very attractive because they can be extremely flexible. For instance, the diversity of standards and regulations in cellular networks around the world carries with it many incompatibilities. An architecture based on SDR will allow future cellphones to switch the signal processing scheme to work on different parts of the world by merely making software adjustments.
This project aims at creating a simple, but functional, software defined radio receiver. This is the final project for the Complimentary Electronics course I took from October to December, 2010. The idea is to be able to receive standard radio (AM) broadcast signals with a desktop computer running LabView and equipped with a data acquisition card.
