When you install a Raspbian Operation System on your Raspberry Pi (I’m currently using Minibian) you can notice that it created a file system with very little space, which can be annoying if you are using a bigger SD card.
I only noticed it when I started to apt-get all those packages that I needed, when suddenly got the message:
cannot copy extracted data for './usr/sbin/php5-fpm' to '/usr/sbin/php5-fpm.dpkg-new': failed to write (No space left on device)
Looking into the SD card’s memory I get:

Who hasn’t spend a lot of money and time on arcades during childhood? What about build one and play all those games again?
Browsing the web I found that a lot of people are building their own machines, building over a pc running a MAME emulator with a cool front-end. If you google images for ‘arcade cabinet‘ you will be amazed by what people are doing!!
I decided then to build my own, trying to use as much used stuff as possible, like a old computer, old screen and two usb game controllers that were broken but with the electronics hardware in perfect conditions. The cabinet will stay on the hackerspace from my town, TARRAFA HACKERSPACE, so we can set some championships, it will be fun for sure!!!
On this post, I will be giving updates on the progress (not much will be done during university semester, I hope to finish this project on holidays).

Few days ago I received a ATmega8A Development Kit from ProtoStack.
The board is well made, and it has everything you need to start developing any kind of project using the famous Atmega8, which is the same ÂµC used by the first Arduino. Actually, you can also use this board with different ÂµC’s such as Atmega168 and Atmega328 (used in Arduino UNO).
The kit have a lot of space to add more components, and a good thing is that the VCC and GND voltage is easily accessed everywhere of the board. On the pictures and the video I posted here, I have connected the output pin PB2 to an resistor, green LED and to the ground, even without soldering the board works great.

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. Weâ€™re working out details, and as soon as we know, youâ€™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

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.

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.
