Graduation assignment at logica

Fri, 27 Aug 2010 21:34:00 +0200

Everything must come to an end! This, sadly, is also true for my studies at the Hogeschool van Amsterdam. Only one more semester and than i'm done. But before i graduate, i need to complete a graduation assignment. I have chosen to do this at logica.nl.

My assignment:
For my assignment i'm going to build a quadro copter with automatic gps navigation.

What is a quadro copter?:
"A quadrotor, also called a quadrotor helicopter or quadrocopter, is an aircraft that is lifted and propelled by four rotors. Quadrotors are classified as rotorcraft, as opposed to fixed-wing aircraft, because their lift is derived from four rotors. They can also be classified as helicopters, though unlike standard helicopters, quadrotors use fixed-pitch blades, whose rotor pitch does not vary as the blades rotate. Control of vehicle motion can be achieved by varying the relative speed of each rotor to change the thrust and torque produced by each." as described on wikipedia.

RPM measurement with GEL2474

Tue, 01 Jun 2010 19:27:00 +0200

For my project "The Spirit of Amsterdam" we have to measure the speed of the vehicle. To do this we use the 'Lenord + Bauer Speed Sensor Gel 2474' with an optocoupler to deliver the data to an atmega32. The code however remains private until the race in Denmark except for the documentation which can be downloaded here.

Oneway Serial communication Library

Sat, 08 May 2010 01:36:00 +0200

A couple of days ago I got inspired to write a serial communications library in the C programming language to facilitate one-way communication between two atmega32 devices.

I know that implementing a one-way serial communication library isn't always practical. Mainly because a one-way connection limits the possibilities for an implementor to do creative stuff with, but in my case, for my home project it was exactly what I wanted.

With just a few modifications, it should be possible to implement a two-way connection, and maybe at a later time I will be inspired to do it myself.

Will be Continued......

Spirit of Amsterdam

Fri, 05 Mar 2010 14:30:00 +0100

Today I joined the "Spirit of Amsterdam" team. The international “Racing Aeolus” race will be held at the Ringkøbing-Skjern airport in denmark and the "Spirit of Amsterdam" wil be participating in the race. Last year, the "Spirit of Amsterdam" came first place and we are hoping to repeat this feat.

The mean goal of the race is to drive as fast as possible against the wind with a vehicle being driven on wind energy. The Hogeschool van Amsterdam (HvA) will be participating in the race of 2010. The vehicle is being built by students of several faculties, teachers and outside experts.

More information wil be available on a later date.

Interview about Project IRI and the Netbeans Platform

Project IRI a big succes

Sat, 27 Jun 2009 14:49:00 +0200

We had to simulate the sensors on a server by generating random values within a certain parameter. The generation of these random values had to be done on the server with a time interval of a few hundred milliseconds and the server needed to store these values. The client needed to access the values of a sensor and show them in a chart. For more information please visit the Software portfolio.

Remove all .svn folders in a directory tree

Fri, 26 Jun 2009 00:27:00 +0200

I have a MacBook and I use the Subversion (scplugin) plugin which integrates with Finder. I use subversion for projects on school together with my project members. When i finished one of my projects, I wanted the code to be included on a CD. However i didn't want the .svn directory’s to be included on it.

A friend of mine approached me and said he knew the perfect solution, use the Terminal and go to the directory you want detach from the subversion server and run the command below. This removes all the .svn directory’s which the plugin created in every subdirectory in the root you have attached to a SVN server.

find . -name ".svn" -type d -exec rm -rf {} \;

The .svn directory’s are now deleted.
