• Open Source Hardware Association

    Just want to share this cool Association that is being created:

    The Open Source Hardware Association is Coming Soon! It will be a non-profit organization (status pending) working to spread the love of open source hardware. We’re working out details, and as soon as we know, you’ll know! Check back at oshwa.org for upcoming news.

    They are asking people to fill a survey so they can know which path follow to make the association. You can help them by filling it here: http://www.surveymonkey.com/s/OSHW

  • DIY: Home UBUNTU NAS Server

    Back in 2003, I used to connect my computer on the my old 32′ TV, those huge and heavy TVs, to watch stuff from the internet, at that time, eMule was ruling the p2p community (can’t talk about USENET right? :} ). Then in 2008 I decided to build a better HTPC (Home Theater PC), a full dedicated computer connected to my TV, with good MotherBoard/VGA/SoundBoard, well, a good computer, with gaming capacities. It was good while it lasted, but you know, it was huge black box below my TV, bit noisy, but it did the job.

  • Dotklok + LM35 Temperature Sensor

    I got my Dotklok up and running some days ago, I am really enjoying it on my room.
    But I want to do more with it. Too bad right now I don’t have much time to play with electronics and build cool things.

    Anyway, today I decided to spend some time learning the Dotklok’s code and add a temperature sensor to it. The result was really cool, and now I am sharing the bit of code I added to the clock.

  • Arduino + Sound Sensor

    I got a sound sensor on Ebay some days ago, and decided to give it a try!
    Really simple, just made a code to light up the led when the volume was higher the ambient sound.

    Just for fun! 😉

    As many people have asked, here goes the code:

    Remember that there are many other ways of doing this, for example using the PWM function along with analogRead() and map().

  • Using Arduino to calculate Quadratic function

    This is a simple and quick code I made for teach variables with arduino programming,
    where we enter the variable numbers a, b, c in

    and we get the answer using the Serial Monitor..

    I won’t get in details about this code, it’s quite straightforward. But if you have any question, just ask! :)

  • My HTPC 2.0

    Long ago, I wrote How I Made my HTPC at my place. Time passes and things change. End of year has arrived, Christmas and everything, so I decided to upgrade my system to a more efficient and cheaper one. The new choices were using a NAS (Network Attached Storage) allowing all files can be accessed from any machine connected to the network, in this case I am using Lacie Network Space 2 2TB storage. A Gigabit router TP-LINK , so far I’m very happy with this router, although. A media player WD-PLUS Live that has an embedded Linux and play videos in various formats, even FullHD , and access online content like YouTube and some radios.

  • Moodlamp Mod

    I made some modifications in one of my projects, my moodlamp, where I mounted it in a CTRL huge key.

    I’m planning on releasing all the project as Open Hardware/Source, but due my lack time, it’s not on my website yet!
    Would you like to take a look at this project??


  • My DotKlok

    Hey, I got so exited about the DotKlok that I decided to build my own! As it’s quite difficult to buy one from here (I live in Florianópolis – Brazil), and to pay U$150 for the Kit wouldn’t work for me… So I want to build a good looking clock for my room, which I only have my computer and mobile as clock.

    First of all, I needed to buy the 24×16 Led Display from Sure Electronics, which I found for a good price at eBay (little cheaper then buying from the Website).

  • Femtoduino: an ultrasmall arduino board

    This is amazing, perfect for those times when your have to create another board just to hold the atmega µC. I am looking forward to use this tiny board in some project in a near future. Congrats to Varesano for the project.

    You can check his project HERE.

  • Arduino-Based Digital Clock

    Wow, this is amazing! DOTKLOK is an open-source, hackable, Arduino-based digital clock that displays a series of unique time-telling animations.

    DOTKLOK: Game Time from The Latest Artists on Vimeo.

    DOTKLOK is an open-source, hackable, Arduino-based digital clock that displays a series of unique time-telling animations. The passing of time is depicted with numbers and abstract/geometric patterns such as Morse code and minimal analog clock faces, and includes animations inspired by classic video games such as Pong, Tetris, Pacman, and Space Invaders.

    You can buy the kit for U$150.00 and it assembled for U$200.00
    for me… I think I will build one, hell yeah I’m going to build one, just love it!!!

    You can check more information from dotklok’s website.
