Projects

No, I did not finish my 3D printer yet, but I have done my first 3D print.

The cap for the wind shield liquid container of my car broke (it’s old, very old), and I needed a replacement.

I came to my computer, took some measurements and drew it in FreeCAD. It was a bit of a challenge, because I’m not exactly an expert in 3D design, but I managed to pull it through (with some help from this youtube clip).

One of my work colleagues has an Arduino kit, that includes amongst other things a stepper motor driver, an ULN2003APG board,  and I convinced him to lend it to me.

This weekend I had some time, so I played a bit with it. After reading it’s data sheet, and comparing some examples I found online with other motors; finding those motors data sheets and comparing their coils connections with my motor, I got to this schematic:

When the craze with the quadcopter drones started, of course I wanted one, so I bought a few (cheap) parts to learn how they work and played aroud with building one. I’ve never finished the project, because…. I don’t know… I „postponed it”.

Now, in the middle of the craze with 3D printers, naturally, I wanted one as well. I can’t afford one, mostly because I’m not willing to spend that much on something that I’ll not use so often.

First of all, sorry for the long absence. I’m involved in many projects and I couldn’t get to this earlier.

Here are the updates:

I’ve bought an extender for the RP pins from Jola Engineering and soldered the shim onto it. Now I can put everything together nicely.

I had a pile of Ice cream sticks laying around and I was looking for something to do with them.

I recently got a Raspberry Pi 2, so I’ve decided to build a case for it.

Some super glue magic and some hole drilling (need to work on my skills here), and voilà.

Two weeks ago was the release of the latest and greatest Kubuntu.

Kubuntu 15.04 Vivid Vervet brought to the market one very important and very significant change: It’s among the first distros to ship with Plasma 5 and the new KDE Frameworks 5.

In celebration of this, together with Aaron Honeycutt, Rick Timmis and of course Jonathan Riddell, I held a presentation of our new Kubuntu at the Ubuntu Online Summit 2015.

After following a course on Coursera, I’ve seen something I’ve liked and thought on how can I improve it.

So I came up with this:

The GeekAliens Linux Workspace Setup

A forked GitHub repository with Linux configuration files which I’ve customized to my likings and thought that this can be useful for anybody.

Yeeeeey…

I’ve just got my first Raspberry Pi.

It’s the B model with 512MB RAM.

Here are some rudimentary first pictures:

Good bye Java swing, Hello Qt.

Cross platform is very searched for these days, especially with the number of Linux users growing. The need to build an application that can be used everywhere existed for a very long time, and what I intend to present here is not something new, it’s just new to me.

Qt, pronounced „cute”, is a library for C++, but not limited to that, that can be used to write code that can be compiled on/for almost any operating system, including Linux, OS X, Windows, Android, and iOS(still under development).

This is a test script I made for easier installation of LibreOffice 3.6 for Debian based Linux distributions with the Romanian Language pack. This does not require any Linux command line skills. Just download the archive and double click the file called INSTALL.sh, and follow the instructions. After the installation, the Installer window will close automatically.
