BarTop Mame Cabinet (under dev)

Who hasn’t spend a lot of money and time on arcades during childhood? What about build one and play all those games again?

Mame Cabinet

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).

Open Hardware MoodLamp

Finally it’s here, my first Open Hardware project, in which I have delayed some years to release due my lack of time to finish it and make it presentable.

For this project I’ve created a Project Page, in which I will be updating in a regular basis.

So I want to invite you to take a look at the
OPEN HARDWARE MOODLAMP PROJECT PAGE.

Open Hardware Definition 1.0 Released

It’s finally here, a document that will help us to define what Open Hardware is, and to spread the idea. Open Software have been around for a long time, Open Hardware is still beginning, but already have a really big community out there, including me. I will add the logo to my next projects for sure!

Now, to move forward, please HELP:

This is a very important step in propelling our movement forward. PLEASE FORWARD FAR AND WIDE.

Working with LEDs and Resistors

The objective of this text is to help you to understand how Resistors work and use it in it’s most simple use, as a current limiter. If you want to know more about resistors and leds, check Here and Here.

Another cool AVR Dev Board

Kyle Stewart built another cool Dev Board for the ATmega168/8 (same microcontroller used in arduino).
The news thing about this board, is that it have a “vertical approach”, leaving more space on the breadboard for other components, a excellent idea!

Some features:

  • Works with ATmega168 (and probably others)
  • 16MHz crystal
  • 5V and 3V regulators can supply power to breadboard
  • Plugs vertically into breadboard taking minimal space
  • ISP programmable
  • 1-wire debug can be used
  • Simple to build, no surface mount components

On kyle’s website you will find the schematic, eagle files and more.

How I built My HTPC

I’ve built my HTPC like one year ago, don’t know why I have never written about it on this website. Well, for today, I will be presenting the place I spend many hours of my life, my Home Theater PC, my Media/File/Gaming/BackUp Server. The idea came many years ago, but without $, it was not possible. Fist my main computer was near the tv, so I used to connect to my old tv using a S-Video Cable and a P2 to a RCA Cable, and as a Tube Tv, the quality wasn’t that good, and I couldn’t almost read any text on the screen, just big texts like subtitles.
