Trainee blog

Welcome to Aros electronics trainee blog 2017/2018. This blog is maintained by Charlotte Lanfelt and Maria Nisshagen, new M.Sc graduates from Chalmers University of Technology, Gothenburg, Sweden. We started here at Aros electronics in late Aug. 2017 and will be working as trainees for a total of 12 months.

2018-07-03 - Soon Summer Vacation

  The summer vacations are closing in on us and soon Maria and I has been here at Aros for a year, time really flies!  In the last post we mentioned that we also could see the finish line on the Six sigma course and now it is actually completely finished and we both managed to get good grades and of course a lot of learning. Now we are just waiting for our certificates.    

Right now all the focus are on our projects here at Aros which as mentioned are supposed to be ready for the big ITMA (International Textile Machinery Association) fair in Barcelona next June. Maria actually just got her ready pcb:s from the production, and she also got them in a very pretty package. So next step for her is to test the functions that she previously designed.



2018-05-24 - Long time no see!

We’re now completely moved in in our new open office and I have managed to get my desk so messy that it feels like home!

What since last update you might ask? Well, Charlotte has been working with a project for a new customer where she got to visit France, I am not jealous at all…


2018-03-14 - AfterCharm and New Offices


Now there has been a month since our last blog-post and it has actually happen some exciting things since then.

First of all we have finally moved back into our original building, due to a big renovation of our offices some of us had to sit in another facility across the street for a couple of months. But now we are back and the new office landscape is really nice and open with a lot of daylight.

We had an opening ceremony last friday where all participating employees had to construct an opening speech together. Afterwards we had a really enjoyable afterwork.


Last time we also mentioned that we were in the planning phase of the afterCharm event, which took place the first of March. It was a lot of students who participated and it was a really fun day and evening. I hope those of you that participated thought so to!



2018-02-14 - New year, new challenges

Hello again,

Now it was some time since we wrote a blog-post. It has been really busy here preparing for the CHARM fair at Chalmers so we did not have so much time left for the blog, but now the fair is over so we will update you on what has happened since Christmas.

First of all we both had a very nice vacation for Christmas and New Years, and when we came back we started off by finishing the NFC project with some documentation since the prototype now worked properly, both the software and the hardware. 

While Maria kept on working on here current measuring project I instead started to get some training in how to run and control the motors we design. Even though I just started it was really fun, but a lot to learn regarding how electrical motors work.

At the same time we also inherited a project stared by two guys who did their summer jobs here at Aros, a Pinball-game-suitcase. They had designed and constructed most of the game but some relevant parts had to be added and/or changed for the game to work properly.  So this game is what Maria and I has spent about three intense weeks with constructing to make it ready for the CHARM fair. We have done everything from creating hall-sensors and amplifier circuits to fix the software and making the mechanics work, both fun and instructive!



2017-12-22 - Merry Christmas!

Merry Christmas and Happy New Year!


2017-12-13 - Rocking fairs

Hi again!

As previously mentioned are we responsible for the work fairs at Chalmers. Last time it was DatE-IT and this time it was the students from the Mechanical Engineering as well as Automation and Mechatronics programs that we guested at ZMART.

The arrangements were smoother this time so I guess it is true what they say regarding practice. Here is Charlotte, ready to rock ZMART. 


2017-11-21 - Three months at Aros!

Time really flies and another couple of interesting weeks has passed.  To start of seriously, our NFC project is moving forward and the hardware is now working fine and detecting the signals from the phone and the digital isolation is finally working with us. The project is moving on towards the software part where we have established contact with the NFC-chip. 

A couple of weeks ago we were with our colleagues to test one of our electrical motors for EMC emissions. Really cool room with all the isolation to prevent reflecting signals and disturbance from the outside. 

As a part of the trainee program we are also responsive for the work fairs at Chalmers. The first fair was DatE-IT. After some hard physical work, heavy lifting and arranging our booth looked like this. 



2017-10-27 - From cinnamon buns to buses

Wow, what an interesting time it has been recently here at Aros.

Since we soon will start the more practical part of our NFC-project we got a basic soldering course to get a grip of the theory behind it and also methods to use when soldering surface mounted components. It was tricky but some practise will do the trick.

The office is being restored and we had to move out from out room to a new one. Look how large and spacious it is.



2017-09-28 - Learning and Adventure Time

Hello again!

Now we have been here at Aros for additional two weeks and it has been a lot of learning and fun. First of all we have kept on educating ourselves in “Aros konstruktionsskola” where we recently have learnt how to work effective in a project and also how to use LTSpice for simulations.

The planning for DatE-IT and ZMART fairs at Chalmers has also started where we will participate.


2017-09-18 - First month at Aros

Hi Everyone!

We are the new trainees here at Aros, Charlotte and Maria. We both have just finished our studies at Chalmers where Charlotte studied Automation and Mechatronics and Maria studied Electric Power engineering.

After one month here at Aros we have finally got access to the trainee blog. So the question everyone has been asking; “what have we been doing here our first month?”
