In the last weeks we started again with the development of ArcheOS 5 (codename Theodoric) and I have to say that the first results are really promising, especially thanks to the work of Fabrizio Furnari and Romain Janvier.
The reorganization of the whole system, planned by Fabrizio, is leading to a better management of the entire project. Moreover the division of the internal software in thematic metapackages (CAD, GIS, etc...) will help final users in customizing their own version of ArcheOS (in accordance with their specific needs).
On the other hand, Romain is working really hard to build source packages of the different applications, so that ArcheOS 5 will be architecture independent.
Last but not least, the 3D artist Cicero Moraes is preparing a brand new artwork for the upcoming release. If you are curious, just take a look on the preview for the splashscreen below.

So, what's missing now? Just you!
We need your help to improve ArcheOS 5!
We want you, and GNU ;)
Any kind of help is welcome! Some examples? You can give us suggestions for a better software selection, or write tutorial (as well as record videotutorial). If you have some computer skills, you can package the missing applications, or develop new ones...
In any case, you can find us as usual on the developer mailing list or, even better, in our brand new IRC chanel (thanks to Fabrizio). The server is FreeNode and the channel #archeos.
I prepared a short videotutorial to illustrate how to join our channel in a fast way.
One of the most interesting things is
that you can take data directly from the .dbf table of the shapefile
layer loaded in QGIS and process them in R environment. Usually, when
I work with PostgreSQL/PostGIS or SQLite/SpatiaLite for managing
attributes table of vector layers, I connect directly database with R
using RODBC or RSQLite packages. But if I have to use shapefiles and
their .dbf tables, manageR could be a good solution, specially
for fast and simple works.
Here, I would like to present a small
example of plugin's use. In QGIS I created a distribution map of
Roman funerary sites in Trentino-Alto Adige region (Northern Italy).
The sites (blue dots) are registered in a simple shapefile and every
single point is associated to a record stored in a .dbf table. As
usual, the .dbf table is divided in several columns each of which
contains different attributes about sites (ID, coordinates, height,
I need to plot an histogram of heights
above sea level to get an immediate view of sites distribution based
on heights. I can launch manageR from QGIS.
At first sight, manageR
is a simple GUI that includes R command line, some toolbars for
managing data, graphic devices, history, etc. and several buttons to
make some of the most common statistical analysis.
As I said, in manageR I can
import layer attributes with button “Action → Import Layers
Attribute” (or CTRL+T) and then I can select the column I need
(in my case, “height”) using R language.
Typing in R command line or using
button “Analysis” in main toolbar, I can select and launch
the statistical function I need and plot the diagram; in my example I
plotted an histogram of heights a.s.l. of my funerary sites.
This is a simple example, but manageR
plugin could be a very usefull tool for archaeologists, also for more
complex works. Its main advantage is that it works directly with .dbf
table, avoiding the export of data or the opening of .dbf file in
It talks about a child mummy of St. Louis, that lived in a range of 40 BC and 130 AD. He died with 7 or 8 months.
Inside the matter had a video with some seconds of a CT-Scan slicing. I was able to convert it in a reconstructed mesh, and after I found a video on Youtbe with more qualty and I used it to make the final mesh, used in this post.
I downloaded the video with Videodownload Helper (Firefox) and it was converted in a image sequence and after in a serie of DICOM files.
Unfortunately I lost the original vetorial file and now we have only the infographic in Portuguese version, like you can see below (but it have a lot of images, that dispensing you to read it).
To make a reconstruction with historical and archaeological foundation I had the help of Moacir Elias Santos, archaeologist of the Egypt Museum and Rosacruz, from Brazil.
The animated gif above shows the extracted frames of the animation converted into a CT-Scan. I reduced the slices to make it more didatic.
I had a serie of dificulties to find landmarks to use on the child's face, cause appear that it doesn't exist. So I use a average of 3-8 year and rescale it to have at least a reference.
I use a serie of babies pictures to draw the line of the neck and ears.
Moacir sent me a compose image with the original mummy, that you can see below.
I hope you enjoy this post. I see you in the next. A big hug!
One of the main problem in doing videotutorials for ArcheOS 4 (Caesar) regarded the possibility to record the desktop activities when using 3D applications. Here is my report about this topic in ArcheOS ML. As you can read, the software we chose (recordMyDesktop) was not able to record videos (just a series of screenshots) of windows displaying 3D objects (like other similar tools: Istanbul, Xvidcap, Shuter).
Since I was using ArcheOS Caesar, I solved the problem with glc, before, and with ffmpeg, later (thanks to this post of Cicero Moraes). These two options have certainly high performance, but they are not user friendly for newbies.
Now that we started again with the development of ArcheOS 5, I think we will need a simple tool to record video of 3D applications and maybe I found a good solution: Vokoscreen.
The video below shows a fast test I did with this software. The data comes from the Taung Project and were developed by Cicero Moraes.
With this new tool I hope that ArcheOS users will help us in doing videotutorials or simply in recording demonstrative videos of Theodoric in action.
Rolf R Bakke Multicopter from HobbyKing (work in progress)
we bought a NAZA dji. It is not a Open Hardware project, but a low cost solution to obtain aerial pictures. This drone has a perfect implementation of the GPS module and a revolutionary way of flight; it offers three types of control modes:
Manual (M) = manual free flight
Attitude (A) = free flight with altitude lock and high attitude stabilize
GPS = free flight with hold final position
The movie below show how the GPS works to hold the position till the remote control gives new moving command.
We didn't try yet the RTH (Return To Home); as soon as possible i will upload a new movie about it.
