bookmark_borderMy moodlamp project
This is a project I have for quite a long time, since before I knew how to use microcontrollers. Now I may study chromotherapy to apply the lamp for this techniques. For now I have it on my room, that I use to relax and it works!
What do you think? 😉

bookmark_borderBuilding a Breathalyzer with MQ-3 and Arduino
During the First Meeting of Electronic Arts in Florianópolis, we built a Breathalyzer using the Alcohol Gas Sensor MQ-3 and an Arduino Board to use in the last day of the meeting, in which we gave a party. You can see a quick video two posts below. Last days I received many emails asking for the code or how to make one, so I decided to build the sensor again, take pictures/videos and make a tutorial showing how you can make one, so here it is.

bookmark_borderCampus Party Brazil
Hi everyone, I am blogging live from the CampusParty Brazil 2k10 in São Paulo – Brazil, it’s something like a Lan Party but full of presentations, concerts and of course downloading… We have here a 10GB BandWidth internet, and there’s a TV screen showing the bandwidth consumption, and we haven’t used more then 3GB at the same time. (I’m trying my best to beat the record). Another thing that I found cool is that someone started a DC++ Servers, and there’s around 400 people connected to it sharing stuff fullspeed, soon my 500Gb Lacie Drive, that I brought with me empty will be full.
In case you are somewhere around the world and would like to download stuff from us, connect to the DC++ Hub cp2010.no-ip.org and download at a great speed.
Today morning there was some people doing Arduino projects, DIY stuff, Open Sorce presentations and much more. You can check LiveStreaming from the Campus Party Here.
Yesterday Kevin Mitnick was here giving a presentation about the art of deception, what a presentation, really good! If you would like to watch it, I am uploading it too, it’s worth it!
Take care all, I will check my downloads now! 😉
