Here are some of the photos I took last weekend, during a walk in Vagos.

The following video shows a prototype of a project I’m working on. It consists of a circuit that reacts to sound, turning two LEDs on and off (really fast), based on signal amplitude and frequency.
The blue LED reacts to lower frequencies, filtered with a low pass circuit, configured with a cutoff frequency of ~150Hz, while the other one reacts to frequencies, filtered by an high pass circuit, with a cutoff frequency a little over 1.5KHz.
I previously posted something similar I did with an Arduino, but now I’m using a full analog circuit. The sound response is much better now! Enjoy:
I have a big interest for 3D programming since a long time ago, although I’ve never done anything about it. Recently I’ve started researching for tools I could use to start learning about this subject. I’ve found a neat library, called Simple and Fast Multimedia Library. It’s open source, cross platform and looked easy, clean, reasonably mature and had overall good user reviews. Oh, and it has bindings for Python, which is incredibly useful for prototyping. There’s also the famous PyGame, which is basically SDL for Python, but from what I’ve read about it, it didn’t look as clean and easy as SFML, but it is considered a good library too.
So, after deciding the library I would be using for the GUI and event handling, I had to start reading (OpenGL documentation, math theories, articles, tutorials) and experimenting with code. Finally, when I had a basic idea of OpenGL workflow, I decided to start a small project – a MD2 model viewer! It was a big motivation. Not only I played Quake series since the beginning, but also Quake2 model format is very well documented. As if this wasn’t enough, Quake is also open source and Linux friendly.
I had (and still having) a blast working on PyMD2Viewer. It currently looks like this:
I’ve started a new project whose main purpose is to show real time details of a rFactor session, similar to http://rfac.ath.cx, but as a GUI application.
The whole project is composed of a server-side component and a client GUI application. The server-side component is basically a socket server, receiving requests from clients and broadcasting session information to every connected client. It is built on top of rFactor2Python.
The GUI application uses GTK, works on Windows and Linux and looks like this:
