BeagleBoard to ID-12 Revisited. 1 Euro Interface

Our previous interface to ID-12 was pretty cheap. Around 2 Euros for a Logical level converter and some wires, but as the ID-12 RFID reader does not need any programming or command in order to work, we end up just using the RX line from one of the available channels in our converter. That looks like a waste :).

BeagleBoard UART2. Interfacing to RFID reader ID-12

Recently we've been exploring the Beagleboard Expansion Header on our old BeagleBoard C3 board running Ubuntu 11.10. We installed Ubuntu following the instructions on http://elinux.org/BeagleBoardUbuntu#Oneiric_11.10. Then we explored the GPIO pins in the header (http://papermint-designs.com/community/node/205) finding out how to use them as inputs and outputs and later we tried the I2C bus (http://papermint-designs.com/community/node/210) using just a couple of components for those of us that do not want to invest a lot of money on simple tests.

BeagleBoard I2C. Interfacing to the WiiChuck

After playing with the GPIO (http://papermint-designs.com/community/node/205) for a while, let's move on through the BeagleBoard Expansion Header. Now it is time for the I2C bus. I2C bus is available through pins 23 (Data) and 24 (Clock).

BeagleBoard. LEDs and Buttons

Finally I've been brave enough to solder a connector into my BeagleBoard expansion header to further explore how to attach different stuff to this little one. After verifying that the board still boots (i.e. it survived my poor soldering skills :) I went for the "Hello World" for this kind of hardware... a blinking LED.

Trying picoFlamingo on BeagleBoard C3 with Ubuntu

Actually, the idea was to reinstall Angstrom and set up a working development system on my old BeagleBoard C3. However after several hours fighting the installation and the documentation I just gave up and I tried Ubuntu. Not sure what was the problem, probably I did something wrong, but as a matter of fact I waste several hours with no result.

Promoting your Business with picoFlamingo

One of the easiest ways to promote your business is to add a screen showing some relevant information on your windows or even inside your premises. For instance, showing some offer or the latest products in the shop, making customer easily aware of the news.

VelcroBox. One Case to Hold Them All

Hiya!

We had already tried to build some simple casing for our Beagles but it looks like we are not the most skilled guys out there so we come out with the idea to build something really easy to assemble and robust against "inaccurate cutting". The result is the VelcroBox.

It looks like this :

picoFlamingo on Pandaboard


We are still testing the latest picoFlamingo version on the different hardware platforms we have available in preparation for a forthcoming stable release. Yesterday we carried out a fresh Ubuntu 11.10 installation on our Pandaboard to check the detailed set of steps required to make picoFlamingo work on this device.

picoFlamingo 0.4.2 Release Candidate 1

Hiya!

We have been working on small improvements on picoFlamingo during the last months. It is not completely ready yet but we think that these updates have to be released. This is a brief summary of what is new in this picoFlamingo release:

- It now builds using autotools
- Basic Texture Manager
- Build-in network capabilities (TCP and BT). NetKitty is no longer needed to run picoFlamingo
- Added slide items groups. Now several items can be grouped together and manipulated at once
- Added special events to image items for easy button implementation (CLICK, ENTER, LEAVE)
- Several minor bug fixes

Fiono 330. Fixing noisy fan

The Fiono 330 fan is quite loud even when it works OK, but some weeks ago mine started to make really a lot of noise. After having quite some problems with this little one (it stop booting some time ago, then the hard drive broke down...) the warranty expired so I took a look inside.

Occam's Razor 6 Available for Download

Hiya!

Finally a new and interesting issue of the Technical and Scientific Magazine Occam's Razor is available for download. In this issue we can find two special papers related to Space; one about SMOS (all the ESA mission details) and another one SPICE (an interesting SW developed by NASA).

This issue also features our paper about Augmented Reality that inspired Ex-nihilo Augmented Reality Tangible Interface, featured in Hack a Day during Xmas break.

Ex-nihilo Augmented Reality Tangible Interface

Ex-nihilo is a Latin phrase that means "out of nothing". The idea comes from the "Impromptu Sound Board", but instead of using a Kinect why not use just ARToolkit and draw yourself the markers?. Check this video.

New Photos!. Pandaboard, Teensy and TI LaunchPad

Hiya!,

It is again that time of the year you spend money!. We had finally bought a PandaBoard and some microcontroller stuff with the hope to materialise some projects in the near future.

Check this image gallery for the microcontrollers and for the Pandaboard. Do not miss the Pandaboard anaglyphs. If you want the side by side version (JPS) just let us know.

How to write stereo applications for LG Optimus 3D. Trying the Real3D SDK

Hi There!

I've finally played a little bit with my Optimus 3D phone. Actually I had played one month ago, but I haven't had time to write about this till now. For the time being I had just installed the SDK, run the samples and taken a quick look at the code.

Produccing 2D images for LG Optimus 3D


As you can imagine, if you get an stereo camera you start to shot stereo photos. Then you have to share them with some other people and you realise that those side by side jpegs (.jps format) does not look that nice in a normal laptop.

So I wrote a very simple program named sbs_proc (Side By Side Processor). The program accepts a single option and them a bunch of files to convert. The current available options are:
