Center of high field MR

The Center of high field MR is located inside the AKH/Medical University complex in the 9th District, Vienna, Austria:

 

If you want to participate in MRI studies, you should consider those criteria prior to scanning:

  • All metal MUST be removed from your body, especially eyeglasses, wristwatches, jewelry, and shirts with metal fasteners near your head (e.g., zippers).
  • All body piercings MUST be able to be removed.
  • Must NOT be claustrophobic or have a history of claustrophobia.
  • Tattoos are generally not exclusionary, unless they have been inked with metallic dyes.
  • NO pacemakers, insulin pumps, etc.
For another MRI check list visit e.g. this UCSF web page.

Medtronic Carelink Personal Website on Mac

I have the insulin pump from Medtronic. It has a very nice feature which can transfer your data from the pump (e.g. blood glucose readings). I used my MacBook for this transfer until Mac OS X 10.9 Mavericks came out. After the update I got this message:


Therefore now I use VirtualBox with Windows to get my data from the pump to the Carelink website with Carelink USB. Anyway I waited few months. But after almost 6 months nothing changed so I wrote to Medtronic on Facebook. Why Facebook? Because I couldn't find their e-mail anywhere.

So if you are interested read further. This is our Facebook correspondence:

Martin:
Well Medtronic Diabetes, I am still quite unhappy about this website: carelink.minimed.com. As a Mac user I cannot proceed further because I have the Mac OS X 10.9 and latest supported version is Mac OS X 10.8. Mac OS X 10.9 was released on 22nd October 2013. Since then I have to upload the data from my insulin pump through virtual machine with Windows XP. I use CareLink USB.I mean it is about half a year after the Mac OS X update and still the same error that my system is not supported. Quite big pain in the ass to be honest.I hope you will fix this soon Many thanks in advance.

Medtronic:
Martin, I know this can be frustrating, but the development, testing and regulatory approval process are designed to protect the safety of people like you who rely on healthcare software to manage their diabetes. Like other software companies, we begin testing with Beta version of a new OS but can only complete the development process once the final version of the software is released. However, unlike many software companies, CareLink is considered “medical device software”. Therefore, once the testing is complete, it is still required to go through government regulatory processes, which can take several months. This creates a time lag between the release of a new OS and our new version of CareLink.

Bratislava - Neusiedl am See

Ak sa chcete vydať na dlhšiu jazdu na bicykli a nechcete sa nudiť len výhľadmi a bezstarostnou jazdou, treba spraviť jednu dôležitú vec: nezobrať si žiadnu náhradnú dušu, pumpu, lepidlo a iné nástroje na opravu bicykla.

Po 5 hodinovom spánku som spontánne vyrazil do Neusield am See. Cesta je veľmi dobre značená a niektoré časti som už prešiel tak som nepotreboval nič plánovať. Nabil som akurát iPhone, vzal veci na prežitie, jedlo a nastavil bazál pumpy na 20%.


Po cca 30. km som pri diaľnici A4 schádzal z nadjazdu a počas obzerania okolia som prudko nadskočil. Obzrel som sa dozadu a na ceste bol len jeden (1!) kamienok. O pár nato sekúnd bolo už predné koleso mäkké. Hodil som bicykel do poľa a potichu som si vyčítal, že si nikdy so sebou neberiem veci na opravu defektu. Toto bol mimochodom prvý defekt na mojom cestnom bicykli.


Prešiel som dovtedy túto trasu: http://www.endomondo.com/workouts/318700117/6284494

Podľa mapy som bol len pár kilometrov od Weiden am See. Mal som plán, že v dedine mi snáď niekto pomôže. Ak nie tak možno v Neusiedl bude nejaký Fahrrad- Service. Tak som šlapal po ceste ďalej. 


Jeden rakúsky cyklista mi ponúkol dušu, ale nemal pumpu. Niektorí cyklisti sa ma pýtali, či potrebujem pomoc a iní len tak prefrčali okolo mňa. Natrafil som neskôr na dvoch Slovákov, ktorí mali pumpu a aj lepidlo! Duša mala dve diery hneď vedľa seba. Dvakrát sme sa to snažili zalepiť, ale bohužiaľ nepomohlo. Lepili sme to akurát na križovatke, kde chodili traktory na tamojšiu farmu. Jeden farmár zastavil a spýtal sa nás, či nemá niekoho zavolať a doniesť novú dušu. Vtedy som si ešte myslel, že to zalepíme. Tak som odpovedal, že som už OK.

Onedlho prišli na križovatku nejakí Rómovia. Rómsky chlapec sa len tak akože prechádzal popri nás, že čo sa stalo. Ostatní nás pozorovali z diaľky. Veľmi zvláštna situácia. Vyzeralo to, že čakajú len nato, kedy odhodím bicykel do poľa a oni ho hneď zúžitkujú.

Chalani čo mi pomáhali s lepením defektu boli z Novej Dubnice a mimochodom sa poznali s mojim dia-kamarátom Tomášom. Tvrdili mi, že teraz v sobotu asi nenájdem žiaden cykloservis. Neveril som tomu, ale pomaly som už myslel na to, že vezmem vlak z Neusiedl späť do Bratislavy.

Zišiel som dole do Weidenu, napojil som sa na cyklocestu do Neusiedl a vtedy na mňa prehovoril taký starček čo šiel žať trávu pri cykloceste (do jarku medzi cyklocestou a železničnou traťou aby som to upresnil). Že či mám defekt a prečo si ho nejdem dať opraviť do neďalekého Gasthofu (okolo ktorého som pred chvíľou prešiel).

V Gasthofe bola milá pekná pracovníčka (Slovenka), ktorej som sa spýtal, či mi vedia vymeniť dušu. Jej vedúci povedal, že to teraz (bolo okolo 14:00) už nevymenia. Videl som, že majú otvorenú garáž a tak som im navrhol, že ak majú môj rozmer duše tak si to vymením sám. No a o chvíľu som mal defekt opravený!


K jazeru už to bolo len pár kilometrov. Vychutnal som si obed (keksiky Indián) pod stromom na brehu jazera a vyrazil som späť domov.


Po ceste som sa ešte musel zastaviť na mieste, kde som dostal defekt. Toto je ten kamienok, ktorý spôsobil defekt. Bol stále na tom istom mieste. A zabudol som ho dať preč.

Astrophoto-experiment: the Moon

I performed my first astro-photo experiment from the comfort of my flat. The moon was in a good constelation with my balcony so I basically needed only to open the window.

I used quite old 60 mm refracting telescope Konustart 700:


The detector was my old DLSR Canon 350D with a T-mount from teleskop.austria.at .


I controlled the shutter remotely with B.I.G MC-C1:


All put together and aimed on the moon:


I set manual mode, IOSO 400 and shutter speed around 1/160 s. And this is my best shot - processed in iPhoto only, 1 average.



I think it is quite far from good. I think the problem was a heat conduction between the outside world and my room. This can cause blur and geometry distortion. Also I still have problems with focusing. It is not so easy even with the bright object like the moon.

Jailbreaking and unlocking iPhone 3GS

On Monday I have bought the iPhone 3GS. According to the offer it should be unlocked. According to the pretty girl, that was selling me the phone, too. Well accoding to the iPhone itself - not that quite.

I tried two SIM cards before buying it but the activation failed and even not-inserted SIM card was not recognized. Because I had no experience I thought it needs to be connected to the iTunes and some updates or restore should be performed prior to activation. So I have bought it and took home.

I did the update in the evening and still the same. My SIM card was not active. I got No service all the time. The girls had perhaps jailbreak on her phone even without knowing it. She just didn't know anything. And that was the problem.

So next whole day - literally whole day - I was trying to jailbreak and unlock the iPhone 3GS. In order to see if other iOS can be installed and find out what actually the problem is. The motivation was to activate the iPhone without the SIM card.

After several hours of googling and trying some IPSW with redsn0w, I found a way how to get running iOS 4.3.3 and unlock the iPhone for any carrier.

According to software Tiny Umbrella I could install only several versions of iOS 4 and iOS 5.0.1. Apparently there were some SHSH blobs for those systems in the phone or the software found some matches online. I am not quite sure how does this all work. You should check this before doing some downgrades definitely.

This forum discussion helped me the most, mainly this entry by dbleug22990:

1.Use redsn0w to restore the iPhone to ios 4.1(ios 4.1 doesn't require backed up shsh blobs)
2.Use redsn0w to jailbreak the iphone, check the box to downgrade ipad baseband.
3.Use redsn0w to upgrade to most current firmware( this will install a new baseband and alow your phone to activate with supported sim)

So here are the most important steps I did:

I have downloaded redsn0w 0.9.15 beta 3 for Windows. You can download iOS IPSW for example here: http://ipswdownloader.com .

I. So the next step was to restore iOS 4.1 using redsn0w. You have to navigate in Extras -> Even more -> Restore.

II. Then perform jailbreak with Cydia and downgrade iPad baseband. The modem firmware version I had was 06.15.00. You can find the version in Settings -> General -> About in the iOS.

III. The modem firmware was 05.13.04 if I am right. I did a "mistake" and made the update to iOS 6.1.6 using iTunes. Then I realized for sure that this iPhone is locked because it could not be activated with my SIM. So I restored the iPhone again to iOS 4.1. At that point the modem firmware was altered.

IV. I installed ultrasn0w 1.2.8 and voilà - the SIM card was recognized and I had the GSM signal!

V. Then I wanted to upgrade the iOS to version 5. iOS 5.0.1 worked but there was some problems with turning my network on and off every minute. So finally I made restore to iOS 4.3.3 which is quite stable now. Of course after every jailbreak I had to install ultrasn0w.



Notes:


A - There is some problem with the modem firmware 06.15.00 and GPS module. I realized today that it is not working properly or at all. Probably you need to downgrade the firmware again.

B - I did not want to upgrade to iOS 6 because of personal reasons
C - Be carefull and buy only unlocked iPhone!

Neuschwanstein 3D Puzz

Neviem už ani prečo, no v roku 2011 som mal pocit, že sa moja rodina nudí a tak som mojej mame a sestre na meniny kúpil 3D puzzle. Netušil som, že tento hrad patrí k tým najťažším stavebniciam. Veková skupina bola 12+ a podľa toho by sme to predsa mali dať. 
Našiel som ho v second-hande Carla vo Viedni a preto som dúfal, že nebudú chýbať žiadne diely.

Začali sme v lete, písal sa dátum 11.9.2011. Prvý stavbársky tým bol zložený z mamy, sestry, Mati a mňa. Po nejakej chvíli bolo jasné, že stavba bude asi pokračovať bez príslušníkov mojej rodiny. Asi patrím k trpezlivejším jedincom.




Po pár víkendoch sme dokázali spraviť prednú bránu a strechu. Keďže sa stavby neskôr okrem mňa nikto nechytal, odložil som ju na čas do izby. To som vtedy netušil, že ten čas bude znamenať asi 2,5 roka.


Zlom nastal 2.3.2014, keď sa k stavbe dobrovoľne pridali Anička, Veronika a Ondrej. Pár hodín ticha, občas rozhovor - to bola Saturday night puzzle party. Ideálny večer na otestovanie pozornosti, sebakontroly a nájdenie autistického ja v každom z nás.
Spravili sme niekoľko veží, stien a ďalšie malé časti. Bohužiaľ sme ich nemohli dať hneď dokopy. 3 hodiny bolo málo. Dôležité však bolo, že voľných častí ubúdalo a tým sa práce na stavbe postupne zrýchľovali.





Nasledujúce nedeľné ráno mi to nedalo a počas dňa som pokračoval tam, kde Saturday night puzzle party  skončila. Práce išli rýchlejšie, počet častí sa zmenšoval. K popoludniu to vyzeralo, že by som mohol hrad dokončiť ešte v ten deň večer. K posledným prácam sa pridala moja sestra, ktorá ma okrem iného podporila aj 4. vajíčkovými krajcami chleba. Odchod do Bratislavy som posunul asi o 4 hodiny.Hrad bol v nedeľu 2.3.2014 konečne dokončený.




Chýbal iba jeden maličký dosť nepodstatný dielik z najvyššej veže. A takto vyzerá hotový Neuschwanstein z 999. častí.
Čas stavby od začiatku do konca s prestávkami: 903 dní
Počet staviteľov: 7

AKG K 420 earpads replacement

I couldn't find any relevant source for changing the earpads for my favorite mini headphones AKG K 420 on the web. So I decided to give a short guide how I have done it.

I have bought this non-genuine earpad replacement in Media Markt (Vienna) - PUNEX Ersatz Schaumkissen. The size (big) I estimated in the shop and it seems sufficient.


0. Motivation. For comparison - old and the replaced new one:


1. I took the old earpad off. You can see the gap around the earpad. I didn't want to dismantle it further.


2. Just with my bear hand I put a new earpad on the headphone.


3. But then it looked like this. The earpad didn't fit tightly.


4. So my trick was to use some sharp and very thin knife. I pressed carefully the edge of the earpad inside the gap all around the headphone.



And that's that. Happy listening.

My Newton 900/114

For past 10 years I used this Newton reflector. However past 3 years not that much. That is also the reason why I am playing with the idea of selling it to someone who will use it more. It is quite good one for the beginners of amateur astronomy, ethusiasts of starry sky and other stargazers. I made some photos yesterday:
