Hello!

As we promised we will give you a picture of our final layout:


This is all parts attached to our own simplified bulkhead that we use during the testing phase as we wait for the real bulkhead to be delivered.

We performed a first vibration test this week which I will tell you more about, but we save that for another post. Now I have to make some adjustments in the SED.

Ciao!

Use copper plates, we said.. It´ll be easy, we said...

The copper plates are driving med mad!! (Mad , I tell you MAD!!)  A fairly easy part of the experiment we all assumed but manufacture these all by our selves have been a highly time consuming process. And we just COULD NOT get it right! (stop laughing! :P)  We do however believe that a working procedure have FINALLY been determined and hopefully we´ll be able to produce several approved copper plates to be used in the upcoming test phase! (Hurrah!!)

Let me guide you all through the evolution of the seemingly harmless copper plate (from hell!) :P

Copper plate v1.0 - 1.3: we went from "punched holes" (= the wavy plate) to drilled holes. To drill in a straight line was apparently much harder than predicted but we did manage to drill straight at the end, unfortunately with the holes not located were they were supposed to be!
Failure 1,2 and 3... 
And what happens when the holes are NOT EXACTLY where they are supposed to be? well, the SCREWS don´t fit as planed!
what NOT to look like... 

We figured; hmm maybe I (Maja) was not the best person to drill in these plates so Robert tried...
Robert vs. plate: 0-1
... and Johanna tried...
Johanna vs. plate: 0-2
...AND Johan tried: Johan vs. plate: 0-3
WE JUST COULD NOT WIN THIS BATTLE!!!
Failure 10, 23 and 101...
UNTIL we finally had a template that wouldn´t betray us! Secured with monkey wrenches, the copper plates are hereby looking according to plan and the experiment tests can proceed without delay! (Hallelujah!)
The Template

Behold! the screws are not in contact with each other and all copper plates now look the same
Thank You all for listening! You´ve been great!

Don´t forget to stay tune for the test phase and remember to tell your friends to like us on facebook! ;) 

Hej då!

Good evening.

First of all we're sorry for the low blog activity the last weeks. Fortunately we have a "good" reason for that; we've been working really hard and can now see the end of the building phase. Our plan is to be done with the building on Monday and after that enter the testing phase for about one month.

Due to the poor updating about the mechanic parts we will go through them step by step.

The Chambers

Here are our chambers consisting of two hats and two bases. The chambers have been manufactured by a local company


Here is the internal layout of the chambers, with the experimental PCB to the right and the sensor PCB to the left, which we've made ourselves.



Before Monday all PCBs will be installed in the chambers using helicoils and the inlet hole for the pressurized chamber must be sealed.

Electronics Box

This is the electronics box we will use with two test-PCBs for the first vibration test. The electronics box shell was ordered from a company, but we have done all adjustments and the angle braces. Before Monday there are two more d-sub contact outlets that are to be made.


Battery Housing

This is the protective house for our two battery packs which was manufactured by us. The batteries will be well insulated against vibrations and the cold using soft insulation pads between the batteries and the walls.


T-rex

For lack of good names; this is T-rex. It will work as a link between the electronics box and the chambers for the d-sub cables. This is because we did not have enough space available on the electronics box itself. T-rex was manufactured by us as well.



Bulkhead for testing

Since we will receive the real bulkhead in mid November, we decided to make our own. This is because we will need it during the testing phase. The test bulkhead is a bit simplified compared to the real one, but will hopefully perform equally in the tests. The bulkhead was manufactured by IRF (our neighbours at school). Before Monday all holes will be drilled and tapped.


If you stay updated on the blog I promise to show you the final layout, i.e. all parts attached to the test bulkhead at the beginning of next week.

During the testing phase we promise to have more activity on the blog with pictures, videos etc.

After this quite massive and facts concentrated posts, we hope you are up to date again in terms of the mechanics group's work in Project SOLAR

Work and Pizza!

Tonight, we all are staying up late to prepare the last detailes before the IPR tomorrow. Some of us are stuck in front of the computer with electronic schematics, others are drilling, cutting, glueing and etching. Some members are soldering, testing components or programming microcontrollers.

It´s practically Santa´s workshop over here! (It is actually snowing!)There is so much going on that we decided to order some pizza and stay at the school til late.


The results from the latest test-session involving electronics gave us some more support about the soldering time-scale and how the process actually will work in detail. Of course there will be even more tests further on so that we can assure that the soldering process meets the requirements! There will actually be a new test session in a little bit to test the interface between the electronics and the software.

Mean while, check out the activity here in Kiruna---->

 Hamoon and Robert is programming

 Vincent
 
 Pizza!
 
 Vincent is soldering one of the sensor PCB-cards
 
Johan is drilling
 
 Hamoon is intrested in all the components!
 
Adrian is fixing some new PCBs
 
 Fredrik
 
Maja, Sara and Fredrik is all about workworkwork!

Testing!

Hi!

Since the last update the electronics group have been testing, testing and testing! We have received some really promising results and we feel that the electronics group has made some really good progress. We are now facing the IPR on Thursday when we will have the pleasure to welcome Mikael Inga and Alex Kinnaird here to Kiruna! 


                 We have also discovered that Hamoon aka "Hamoon Scissor-hands" likes to cut things and I     managed to catch him in action:



                   He starts out innocent as an angel, pretending to help us out preparing some solder-tests....


                                                       ...he continues to fool us all......

                                                 but suddenly....he starts cutting other stuff!

                                                                       NO Hamoon!
                                               
                                                         In the end, no one could stop him........

Further testing

We are currently performing tests on a daily basis. Today, tests were made with the battery pack and the actual array which will be used in the chamber of atmospheric pressure. 


Before

After

The call for proposals to REXUS/BEXUS is now open!

Good day folks!

There is now time to apply for the next round of REXUS and BEXUS! Hand in your proposal before the 22nd of October and you are in the run of becoming americas next top model!, well maybe not but at least a pretty cool person. I mean, how many can say that they sent their own, self-built, experiment on a rocket to space!!??? It is not too late to fill in an application so what are you waiting for??

Here is some more information about how you apply, etc :  http://rexusbexus.net/index.php?option=com_content&view=article&id=59&Itemid=72
