Hardware

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.

This post came in a bit late, because I was unsure of what to write. I’ve been pretty busy this month with work and some family matters, so my contributions were pretty much non existant. Or so I thought. Then I remembered:

Contribution to Free Software is not just writing code, it’s anything you do for the improvement of a Free Software project.

This includes bug reports, translations, meetings, promotion, etc. And I’ve done plenty of those.

Let’s see now: (in what ever order I remember them)

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.

I won a Raspberry Pi Geocache kit and it arrived yesterday, so I decided to go ahead and pursue my wish to have a vlog, and what better opportunity than now.

I’ve rigged some rubber bands to my lamp to hold my phone in place and after a few short tests: away I go: Let the unboxing start!

After the recording was finished I used KDE Connect to get the video files to my laptop and then what else but Kdenlive to edit it. I’ve learned a few things while doing this:

Odată cu sosirea primelor piese proiectul Quodi a început.

Quodi este un proiect inițiat de câțiva pasionați ai informaticii, mecanicii și jucăriilor și are rolul de a educa membrii în tehnicile necesare construirii și controlării pentru început a une drone (elicopter cu 3 sau mai multe elici).

Prin aces proiect membrii echipei doresc să învețe printre altele, cum se controlează motoare de mare viteză folosind

Yeeeeey…

I’ve just got my first Raspberry Pi.

It’s the B model with 512MB RAM.

Here are some rudimentary first pictures:
