How to calibrate the HTC Magic compass

If you have like me used the HTC Magic built-in magnetic compass for a while you might have noticed that it is not always properly aligned. Here is a procedure to re-calibrate the compass and accelerometers in the mobile so that it should give you pretty accurate readings once more:

  1. It does not matter if you are running any special software or not but I recommend you put the phone in the desktop home state.
  2. Make sure you are standing in an open space, preferably out doors, away from power lines, rail roads, large magnetic objects.
  3. Hold it flat with the display facing the sky. Hold it steady and make sure you do not drop it in the next moment!
  4. move it in front of you in large figure-8 patterns in five complete rounds.
  5. Hold the phone upright with the display facing your belly.
  6. Repeat the figure-8 movement again for five complete rounds.

The calibration of the compass and accelerometers should now be pretty good.

If at any time you feel the compass is not showing you the right direction or seems ”stuck” even if you are turning, then repeat this calibration and it will come alive again. Certain applications such as the metal detector application may also screw the calibration and you might need to repeat this after using such software.

Om du som jag har använt dig av HTC Magics inbyggda kompass ett tag så har du kanske märkt att den inte alltid visar så rätt. Här nedan följer en procedur hur man kan få den kalibrerad enkelt och visa rätt igen:

  1. Det spelar ingen roll om du kör någon sorts mjukvara eller inte men jag rekommenderar att du stänger av program och låter den vara på den vanliga desktopen.
  2. Se till att du står bra i ett öppet område, helst utomhus och inte i närheten av kraftiga magnetiska fält eller objekt.
  3. Håll telefonen platt i handen med displayen rakt upp mot himlen. Tappa den inte i nästa moment!
  4. För telefonen i stora åttor framför dig i åtminstone fem hela varv.
  5. Håll telefånen nu med högtalaren rakt upp och displayen mot din mage.
  6. För telefonen återigen i åttor framför dig.

Accelerometrarna i telefonen skall nu ha hittat sin jämvikt och kompassen bör stämma relativt väl. Du behöver göra om denna kalibrering ca 1 gång om dagen i normalfallet.

HTC Magic

What I have used before…

So this is my new friend and toy. I have previously been an Ericsson fan until they released the ridiculous K600i telephone and then I switched to Nokia N95 for a short while and I detested the Symbian OS completely. So then I tried a Windows Mobile based HTC the Dual Touch model and my current work provides me with a HTC S740 which is also a windows mobile but with some nice features like GPS and so on. Last thursday however I went and bought myself the first big Android phone released in Sweden, the HTC Magic through the operator 3.

Just WOW!

I can honestly tell you that this mobile has become one of the best gadgets and most useful tools I have ever possessed and in a very nice package. The mobile looks a little bit like an iPhone, slightly smaller display area and with a few more buttons on the front side. However when it is started it is obvious that it har borrowed even more from the iPhone in terms of the interface but also it is far from the special locked down feeling that I get from all Apple’s stuff.

The great Google Mobile!
The great Google Mobile! Picture shows a Vodaphone mobile, mine is without that logotype but otherwise the same.

Connector

First of all the multiconnector contact on the phone is a slightly modified USB connector. The modification is only there so that you won’t insert audio connectors into a normal USB but they will fit your phone. However normal USB cables will fit the phone so you can connect it to any laptop or desktop PC or mac just like that with any normal USB connector.

The phone charges over USB and syncs really well. This has been the standard for HTC phones for quite some time now and I hope that other makers of phones will abandon their special connector solutions and just use a normal USB plug or a lightly modified one like HTC does.

Battery time

The battery is depleted quickly if you are surfing a lot, streaming music running the GPS and so on but if you are using it in stand-by mode it will keep you happy for a couple of days at normal use. In the beginning you will probably – like me – need to charge it nighly because it is just so fun to try all the features and bring up the GPS assisted maps, stream YouTube when you are bored and so on. Of course using heavy applications and lots of 3G and HSPA data networks will definitely use up the battery quickly.

But I have no complaints really, if you are conservative with you will probably not have to charge it more than every second or third day. It also recharges pretty quickly if you use the wall plug charger. Charging over USB from a computer that can only deliver 500 mA maximum takes of course much longer.

Software

The software for syncing and backing up is included on the phone. Connect it to your computer using the USB cable, then mount the SD card that comes with it and the sync application, manual et cetera is showing up on a removable disk volume. Just install the software straight from the phone and you are ready. Or look something up in the manual.

Adding your MP3 music is just as easy, just drag them to the music folder on your phone, allow the copy to finish and then you are done. The copying is pretty fast as well, seems to be USB2 which is so much faster than my older HTC mobiles that was taking forever to store music.

Oh, and the mobile can be used like normal whilst connected to the PC with the USB.

Android OS and Interface

The Android OS is developed by Google and this is obvious from start when setting up the phone since it asks for your Google online username and password. Once given to the phone it syncs the calendar and mail account with the online GMail and Google Calendar and many other services you might be using such as GTalk and so on. Lovely stuff if you like the G approach to online life then this phone is definitely for you! It also have mail applications that can handle Exchange mail and normal POP/IMAP accounts as well of course though I have not had much use with these yet and gmail is doing the job rather nicely for me.

The interface is smart, sleek and very fast. I have not been able to make the phone slow down yet with the applications I have been running. The menus just slides out and back again really smooth and nice. The settings in the phone is very logically arranged and it just takes seconds to find something you don’t have to hunt around in an obscure menu system and most of the things just works out of the box.

The on-screen keyboards

There are several of on-screen keyboard to chose from and whenever you touch something to type the phone gives a tactile response by a very short vibration. This is really great because most touch keys are difficult to see if you hit or not because even if the key gives a visual response the finger usually blocks the view! Great thinking here.

Swedish keys are located on one of the keyboards directly and in the others you will have to press the A button or O button down to bring up a row of accented characters and then slide your finger off to the Å, Ä or Ö characers as desired.

Sky map

sky-map

The mobile features a GPS receiver, a magnetic compass and accelerometric sensors that can tell how you are holding the phone. And of course google has released a real killer app to go with that, the google stars. Go out on a starry night, give the GPS a few seconds to locate your position (or use the cell towers to triangulate your position down to a few hundred yards accuracy) and then start the Google Stars app and hold the mobile up to the part of the sky you are viewing. Instantly the mobile will show you the stars and their names, constellations, where the polar star is and show you the positions of the planets and so on. I can’t really tell you how fun this is – you just got to try this out yourself. Incredible!

Navigation for car and by foot

Oh I already mentioned the GPS. It loads information over the network where the satellites are so it aquires a position within seconds when outdoor. If it can not find a GPS fix it will still give you pretty accurate position based on information from the cell towers if your operator supports this. The magnetic compass shows where you are heading and the GPS plots your current position on Google Maps. Now just find where you want to go and it will take you there. Really good for finding addresses, stores, shops, people… searching on the map ties in to many other databases on the Internet and usually gives you really accurate information. I am a jogger as you might have come to know by now.

One of the more esoteric application is a metal detector that detects ferro-magnetic materials. It’s quite funny and uses the compass of course to do this but it is great fun. It may even be useful to locate  stuff in walls…

Geocaching

The phone with GPS and magnetic compass also have applications for Geocaching through the Application Market (where most apps are free) and I have tried out the GeoBeagle application which is a really great app. Press a key and it will take you to the Geocaching online site listing the closest caches for you that you have not already found. Select one of them and then press view as a google map and GeoBeagle snatches it up, shows you a directional compass where to go, distance, accuracy of your position and you are ready to go.

When you find it you just press a key to log your find (or DNF, did not find, as it may be) and you have logged another cache. So simple

Cardio Trainer application

Yesterday I found another killer app that you can use that plots your running on a google map, keeps track on your progress in tempo (minutes per km or mile) and distance and time in km or miles and minutes. The application can also be set to regularly announce the tempo you are currently keeping and how many kilometers you have been doing so far and on what time. So, with the built in MP3-player and this application I sat off. One minute later the mp3 music fades slightly, then a voice announces that I am doing 6:30 minutes per km. Later on when I reach my first km running the voice tells me that I have now done 1 km in 6 minutes and 52 seconds and so on. Makes you really aware on how fast you are going, if you are keeping a good tempo or slacking off or if you are pushing harder than you wanted. When finished you can upload your track to the web to have more information about it there, share with people or just compare several runs with each other.

I really really like this!

Public Records Office II

I had the grand fortune to be able to re-visit the old public records building. I found when I came home from the first time that I had unfortunately missed many details that I remembered and I also did not find the basement with the elevator machine room and the attic where I think some nice pictures could be made.

Therefore – here is my re-visit to the Public Records Office here in Stockholm. If you have not seen the first article then you should read that one first.

Now you are welcome to follow me into this fantastic place. The building is bein re-made into a place for children, which I think will be really great – very Harry Potter-ish in many ways. So welcome into the magic world of designed offices from the 1880:s.

The Corner Stairs
Corner stairs again. This time the sun was shining right outside and I wanted to get a special effect from the light to show the relative strength of the sunlight. I think I got it where I wanted to. It looks like an H-bomb just went off outside...
Door handle
This is the lock and handle on the doors that separates the different archive rooms from eachother. They are built in very sturdy boiler plate stell to provide safety from fire. Most doors also have signs telling people to keep them closed to make it harder for a fire to spread through the archives.
Atlas Window
This is a detail from a window frame where the Swedish compandy ATLAS here in Stockholm can be made out.
The ventilator
An adjusteable ventilator. There are ventilation shafts within the walls of the building in some room to provide for fresh air to circulate.
Cartons
Some of the old binders and collectors remain, but they are empty. I wonder why they have been left here when everything has been removed from all of the other shelves. Perhaps as a reminder of what it might have once looked like when the shelves where full of these things...
Stairy Case II
A stair case leading down into the basement. We found this when we went exploring the darker and more dungeon-like parts of the archive and had to go back and get the camera and tripod. Was looking for the engine room for the elevator.
Single Light
This is the last level of the archive before we actually get to the attic of the building and it has a different design. Here there are no big windows letting light in and there is a large wooden cupboard at the end that used to hold some special volumes. I am guessing that not everyone had access to this part of the archive. Maybe here is where the dark secret magic books where kept?
Attic Wall and Roof
This is a part of the attic, the wall and the roof and concrete supports. I just liked the various textures here. It was really hot up here even if the temperature outside was not so high but the sunshine on the roof made it easy 30-35 degrees in here. Hot and dusty.
Water Expansion Cistern
I believe this is part of the heating system in the building, the expansion tank. As you can see it is designed in such a way that a small leak here would lead the water away over the floor to an outlet that would let it drain through the wall without harm. I don't think this part is being used any more, the wood looks old and cracked and not in use.
The Atomic Radiator
This radiator looks like something out of a Russian movie. Perhaps somethingt from the battleship "Potemkin" but in fact it is another type of radiator used to heat the building. This one is located in the attic of the public records building and the design is modular. It is apparently so that you can put more of these modules together if you need more heating power.
Attic
This place looks like something out of a computer game such as "Unreal" or similar. I am just expecting someone to enter with a rocket gun, circle strafing around me firing rockets high and low. A really strange feeling. Imagine what fun you might have with some paint ball gear around here... :-)
Attic Skylight
Here is another shot from the same room as in the previous picture.
Light play on the floor
Some nice patterns of light and shadow on the floor of one of the upper levels here.
ATLAS STOCKHOLM
This is the details on the base of one of the column radiators. Again it is the ATLAS company here in Stockholm that delivered these.
Decoration Detail
Details of the iron support pillars. These pillars are very nice and you find them pretty much everywhere in the third floor with the offices.
The Archivist's Room
The state archivist's office. This is the grand office in the building with doorways to the left and right to study rooms and secretary rooms. Two huge windows for letting the light in and a very nicely decorated ceiling designed in a way to provide a natural attenuation of sounds in the room. The electrical light is not typical for the times but added later, perhaps in the 1940s or so. The same for the radiators which is a much more modern type of radiators compared to the ones found in other places in the building. I really like this photograph myself, one of those I will always remember shooting. I have corrected lens distortion in photoshop and used three different exposures at 14 bit RAW before combining them to this image.
State Archivist's Office
The entrance to the archivists office. The offset in colour temperatures between the outside and the indoor lamp light is rather obvious here.
Archivator's Ceiling
The ceiling in the archivist's room. I was laid flat on my back when taking this photograph.
Staircase
I love these stairs that are build in several places in this building. They are also made by the ATLAS company and actually I saw one exactly like this in a coffee shop on Ringvägen close to Skanstull metro station when I went in there for a cup of coffee a couple of days ago. I did not ask if they had put their stair case in or where they got it from but the design was exactly like this one although the rail was a little bit different I think.
ATLAS-STOCKHOLM
A close-up shot of the stairs of the stair case in the previous picture. Complete with the company name.
RIKSARKIVET - TEVIKRASKIR
This is the window above the entrance to the building with that yellow light that seems to be always shining. You can see the letters RIKSARKIVET but mirrored.
Arch
A painted arch above the doorway on the third floor of the building. These paintings are pretty much everywhere in the "nicer" part of the building.
Elevator Machine Room
This is the entrance to the machine room for the elevator in the building. Originally the building had no electricity but then it also seems to be proud over that it was the first public bulding in Sweden that did have an electrical elevator. I am not sure when it was installed but they installed it in a separate room with a boiler plate steel door in order to be able to contain any electrical fire that might result from it.
Elevator Machine
The elevator engine, drum and controller. I believe the engine was modernized in the 1950s, it does not by far look as old as the rest of the machinery and probably the wire has been replaced as well. However the controlling mechanism seems to be original.
Elevator Machine
All these three pictures from the elevator machine room was taken in darkness shot with a hand-held flash light used to light paint the room into the right mood. I really like this technique.
The Corridor
Corridor in the basement.
Toilet Stalls
Three toilet stalls. On the middle one it says "Tryckeri" which means printing but there is also a second more litteral meaning in Swedish and it means "a place where something is pushed". Suiteable for a toilet. Lit by a key chain diode lamp and long exposure.
Courtyard Looking Out
Part of the court yard and gate into the back side of the public records building.
Gate
Just look at the iron works of this gate...
Window Drain
An interesting solution here. Especially in the winter time condensation on the windows was a common problem and the solution here was to catch the water before it could drip onto the floor and instead lead it onto the radiator where it would be evaporated. Nice solution!

WordPress 2.8 Editor Problem

After the upgrade to version 2.8 of WordPress my visual editor, the TinyMCE editor used to edit most of my posts disappeared and did not want to start at all. I tried four different browsers with the same problem, Google Chrome, Mozilla Firefox, MS Internet Explorer and Opera and they all had the same problem.

I found other people on the web with similar problems with various solutions but nothing they did helped me so after some trial and error this is what I did and it worked for me:

  1. Disabled all plugins.
  2. Removed the site from ”Gears” in firefox browser.
  3. Cleared the entire browsing history, cookies, and all user data from the browser except for saved passwords.
  4. Logged in to the site and went to ”Tools->Upgrade” and did a re-install of the 2.8 version of wordpress.
  5. Re-enabled the plugins I wanted.
  6. The visual editor now works.

This solved the problem also in Google Chrome but required a restart of the web browser. The Gears is disabled in the ”under the hood” settings of Chrome.

I hope others may have some help from this because it was rather annoying. I think it was a problem with saved cookies in combination with the google gears.

Stockholm Marathon

We went to watch the Stockholm Marathon 2009 today and it was a great party really, so many people everywhere! And so many people running today, it was great to see, a wonderful bunch of people from everywhere running together or spectating.

We had a picnic at Långholmen close to the dreaded bridge Västerbron which is a rather tough part of the track. The runners pass this point twice and I took some pictures from the crowd running.

We were also looking for a couple of people we knew who would be running but since it was really crowded at times I think we missed them all in the crowd. Sorry, we still cheered for you!

Västerbron
The dreaded bridge. It's quite long and the first part is all uphill and terrible. The next part is downhill and also terrible :) Runners pass this at km 12 and km 33.
Runners
People running happily about.
Runners
The more crowded bunch are coming. Look at all the spectators on the left hand side!
Runners
Some was running quite cool, others looked like they'd drop dead. This guy here was cool.
Runners
More runners...

Photographing from Kilimanjaro

A friend revealed at the last movie night gathering that he is going to Kilimanjaro and asked for some advice on what equipment to bring and I thought I would collect my own thoughts on the subject. Loving to walk around in the woods and hiking in the more mountainous areas in Sweden I have a little experience and I would like to share my thoughts on that subject.

First of all everything depends on your weight constrains. Do you have people who can share your load and help you carry camera gear and are happy to do so, then you have a bigger freedom. Do you have to carry everything yourself, taking into account that the partial oxygen pressure at 4 000 m above sea level is about half the normal pressure you probably wish to slim it down. Therefore I will make three recommendations, one where weight is an issue but not a big problem, one where you are a bit more weight consciousness but you might be able to share lenses and other equipment with a friend or two and the last one is if you have to carry everything yourself and must minimize the weight.

Camera body

The camera bodies can be divided into mainly four groupings, the entry-level cameras, the more advanced hobbyist cameras, the semi-pro segment and the professional high-end cameras. Each of them have various advantages and disadvantages and the best camera for an expedition like this is a trade off between several different factors such as weight, capabilities, picture quality and ruggedness.

Below is a table that shows a comparison between many common models from Nikon and Canon, it is not complete but if you want you can help me by submitting more information through email or by leaving a comment on this post. I also have no experience with cameras of other brands so that would also be appreciated if someone would add more information.

In the table below type refers to the four main types of camera bodies that I talked about earlier, size is a grading where 1 is the lightest house and 5 is the most heavy house. Weight is similar to size in this aspect, price is a subjective feeling for the cost for the house alone, quality is a subjective idea of the picture quality the camera produces (and not fixed to the amount of pixels alone but a general feel for noise at high ISO settings and so on). Rugged means the camera is less suited to outdoors activity (1) or better suited (5). Notice that no camera actually gets a 5 here, this is to mark that all cameras are sensitive but handles shocks, dampness, dust and moisture more or less well.

The comparison is also subjective based on personal experience and friends suggestions so you might think your model got an unfair rating in one or more of the columns, you are okay to leave a comment and tell me about it and I will consider revising the table.

[TABLE=5]

Click on the column headers to sort the table for each parameter you are looking at in order to determine what you think would be the best type of body for your expedition!

Which is right for me?

If size matters mostly you should take a look at entry-level and hobbyist cameras. They are slimmer in size and also weigh less than the other cameras. However they usually do not deliver the same quality of pictures as the more pricy, hefty cameras but this should not be a problem mostly since it is much more up to the photographer than his equipment how good pictures becomes in the end.

If you can expand a bit on size but still wish to keep the weight down, take a look at the semi-pro range. This is where you will get the most bang for the bucks and the most quality for the weight and size of the camera.

If you are a professional photographer demaning the absolutely best from your camera, then you already know what to take with you. Of course you will take your beloved D3 or 1D camera to the top, no matter the size and weight of it.

Lenses

The next problem is to find out what lenses to take with the camera body. I will recommend three lenses if weight and size is not a constrain and this is the normal recommendation always:

  • A good wide angle
  • A great normal
  • A good telephoto

And it is here the DX format cameras have an advantage. You get resonably good lenses for a good price and low weight which means you might bring an extra lens compared to the full-frame FX format cameras where you need more hefty and expensive glassware to go with the body.

Not only are the lenses heavier for FX cameras because they have to deliver a wider image circle to the sensor but they also need a step up in quality because of the added resolution. A cheaper lens will show that it is a cheaper lens on a higher quality camera body more than on a lower grade body.

Lenses for Nikon DX body camera

DX-body recommendations, 3 lenses

Now, here are some recommendations of lenses for a Nikon DX camera setup that I think you would find reasonable:

Nikkor AF-S DX VR 16-85 f/3,5-5,6G ED-IF

This is a sharp lens that gives you that extra in the wide angle area and also goes all the way to work as a pretty good normal lens in the range of 30-70 mm as well. Really this is a gread all-round lens that you can find use for in almost any situation.

The VR function to reduce vibrations works very well here and gives you the ability to shoot scenery with as much as 4 stops lower light than you would without it! This is really great.

The disadvantage with this lens is that it is not very strong in low light conditions and therefore I would recommend another lens, the famous;

Nikkor AF 50 f/1,8D

This is a cheap but very very good lens. Gives you crystal sharp pictures, can be used a low light conditions with no problems and is great for portraits and details as well as panorama pictures where you shoot several pictures in order to later stitch them together to one large photograph. One of my personal favourites of all times!

Nikkor AF-S VR 70-300 f/4,5-5,6G ED-IF

This is a really neat lens to get close to wildlife. Especially on a DX body where it gives you the equivalent of a 500 mm lens on a full size sensor body. It is just plain lovely and I love this lens. It is sharp, low in distorsion and reasonably light weight as well as the price is not bad at all.

The VR function means you are able to shoot hand-held at 300 mm even in moderate light conditions! Few other lenses would allow you to do that.

DX-Body recommendations, 2 lenses

Nikkor AF-S DX VR 18-200/3.5-5.6G ED-IF

This lens is a one stop shop. If you can only afford in weight and size to take one piece of glass for your camera get this one. I know the sharpness is not the best but the usefullness of this lens to go from a good wide angle to a reasonable tele is just priceless! And the the price on this lens is also pretty neat. You may even find used lenses for half their new prices on Ebay or similar places.

One thing though, when you walk with your camera this lens has a tendency to extend by itself. Get some rubber bands or something to keep it from extending by itself when you walk and you should be ready for anything really.

The 18-200 is good for wide angle nature shots as well as portraits and you may also zoom in to capture that wild-life that happens just out of reach of other lenses.

Nikkor AF 50/1.8D

Because it is so light and you can use it for so many different things including lovely panoramas (hand held no less). Take it. It weighs almost nothing and the size is really small.

DX-Body recommendations, 1 lens only

See the two lenses recommendation above. I mean that, seriously, the 18-200 for versatility and the 50/1.8 is so small, cheap and light in weight there is absolutely no reason for you not to take it with you!

FX-Camera recommendations

This is very tricky really because if you are using FX cameras you have already committed to heavier gear and so perhaps you do not have the same constraints in weight and size. However, if you want to keep weight down the f/2.8 lenses are very heavy and you should try to find alternatives. The 70-300/3.5-5.6 described in the DX section works equally well for the FX cameras so this would be a given light telezoom of reasonable quality to bring.

One or two fixed focals such as 30 and 50 mm would be very useful as well for shooting low light conditions.

Vibration reduction

Lenses with VR are great especially if you can not afford to bring a tripod for the weight or the cumberness of it. However it does not replace a good fast low-light lens because it does not help with moving objects for example.

Remember that when the camera is tripod mounted or otherwised fixated you should turn the VR function off. Otherwise it might actually cause blurred pictures! And it also uses battery power for no gain.

Batteries

Make sure you have batteries with you. Since you are away for days and will not be able to recharge it is really good if you can get a battery grip for your camera that you can use ordinary size AA (R6) batteris in since you can find these batteries in almost everywhere in the world and the alcaline version keeps for ages in your bag. It also takes just a few seconds to replace the batteries when you need to.

Many cameras also deliver more performance when you use battery grip with the camera. As an example the Nikon D300 camera can deliver 5 frames per second continuous shooting with the standard battery. With 8 size AA batteries in the battery grip you can get a whopping 8 fps from it! This is something that you normally would not expect unless you were using the most professional types of cameras. Check your specifications! 8 fps is really great when shooting fast events such as wildlife!

Batteries are heavy but make sure you have enough. Make sure you also know roughly how many pictures you are able to take before it is time to change batteries. Keep in mind also that in cold temperatures batteries do not fare well in delivering their energy and will go flat much faster than in moderately sized temperature. Also beware of old batteries leaking in hot temperatures, remove from camera and store in sealed watertight plastic bags until you reach some place where you can dispose of them safely and environmentally sound!

There are solar chargers on the market that claim they can charge 4 x R6 or 4 x AA sized batteries on solar energy given 12-20 hours of sunshine. I would not rely on these for an expedition like this. Keep alkalines ready to use!

Accessories

Tripod

A tripod is always a best friend of a photographer. But it is also a rather big and heavy item. However the usefullness of a tripod can not be stressed enough really although it is up to you if you can carry it or not. There are also other options that can be used during certain situations that works well and in this section I will attempt to discuss some of them and their advantage or disadvantage to a proper tripod setup.

Bean bags

These are really simple things, you can make them yourself quite easily, make a rectangular piece of cloth, doulble the langth compared to the witdh. Stitch two sides of it together carefully, then fill it up to 2/3 with something like dry rice, lentils, beans or something similar. Stitch the last part together and you now have a ”bean bag” which you can put on a stone or similar to rest your camera on serving as a crude but pretty effective tripod.

If you are using a longer telephoto lens, then the lens will also need the support of one or more bean bags and you can make them in different sizes for different situations. Then when you put the camer on to them you can push and prod the bean bag until you get the right framing of the scene you are trying to shoot.

An added bonus is that you can boil the beans as emergency rations should the need arise.

Gorilla pod

The gorilla pod is a short snake-looking tripod construction but it mainly works well for lighter cameras. If you are thingking of using one of these you should check it out with the different lenses that you are going to want to use. A too heavy lens will make the gorillapod seem like a toy.

Memory cards

Not much to say, bring enough. Depends a little bit on how you work with your camera but bring more than you think you need. It is always hard to start erasing pictures in camera in order to fit more pictures. You never know until you are back home eactly how the focus went because you need to view the pictures on a full screen or at least bigger than on the display back on the camera.

And don’t use that display to judge the exposure, for that you need to learn how to use the histogram in the camera. The display is nice for checking framing and when you zoom in you get some idea where the focus went but for exposure it is very difficult to use.

EU Försöker hindra avhopp från datalagringsdirektiv

Som ett led i att tvinga fram bodströms datalagringsdirektiv i Sverige har EU-kommissionen lämnat in en stämningsansökan eftersom Sverige aldrig lagstiftade att internet- och teleoperatörerna måste lagra uppgifter av sådan art att man kan spåra vem som gjort vad.

Eftersom datalagringsdirektivet enligt uppgifter kommer röstas igenom som lag i höst så kommer stämningen som en sorts säkerhet att vi inte gör fel här uppe i norr oavsett hur det går i röstandet till EU-valet nu den 7:e (där kanske piratpartiet får fler platser än någon hade trott) utan gör som vi är tillsagda och snarast inför direktivet i svensk lag.

Ars Technica har en artikel här.

Direktivet är ännu ett led i övervakningssamhället som Tomas Bodström (s) såg i sin vision när han drev den typ av politik som senare lett oss till bl.a IPRED och nu datalagringsdirektivet.

Heja integriteten.

Kraftigt Ljus

The ray of light shot hand-held from the south part of Kruthornsvägen looking NNW.
The ray of light shot hand-held from the south part of Kruthornsvägen looking NNW.

I lördags natt på väg hem från en filmkväll i Sollentuna på Kruthornsvägen observerade vi denna mycket kraftiga ljusstråle som sköt rakt upp i atmosfären. Vi konstaterade att lyseffekten måste vara på åtskilliga kW för att kunna åstadkomma detta och strålen var synlig flera hundra meter upp i atmosfären och måste definitivt ha synts väl för flygplan.

Vi vet inte vad detta var för något men någon sorts anläggning  måste det vara. Eftersom vi hade parkerat bilen en bit bort så promenerade vi Kruthornsvägen fram och konstaterade att vi kunde triangulera strålens position ganska bra. Det visade sig att den med största sannolikhet kom från en bergsknalle i närheten av Kruthornsvägen bakom hyreshuset på bilden. Vid en första anblick på Eniro, Hitta och Google Maps hittades inget men sedan började jag se spår av att bilderna photoshoppats och något har dolts.

Om man sedan tar en titt på 3D-vyn hos hitta.se samt flygfotot från Eniro som båda visar att det finns någon sorts anläggning på platsen. Ringarna är väl antingen en grillplats eller kraftiga lampor, det ser ut som om det ligger några små bodar eller skjul på platsen. Jag har ingen aning om vad det är för något.

På bilderna ovan sitter det olika färgade cirklar i närheten av de objekt som verkar vara intressanta det röda markerar något som skulle kunna vara kraftiga strålkastare (eller grillplatser!) den blå och gröna markerar någon sorts mindre hus eller skjul på något vis som verkar ha med anläggningen att göra. På den nedersta bilden syns också en del av det hus som finns med på fotografiet längst upp i denna artikel.

Jag kollade inflygningsbilden för Arlanda flygplats och det finns ingen markering där såvitt jag kunde se och strålen ser definitivt inte ut som ett inflygningsljus brukar se ut heller. Länskartor kunde heller inte kasta någon sorts ljus över saken utan noterade bara att det låg några (!) transformatorstationer i närheten, kanske något fler än vad man förväntar sig i ett ganska litet bostadsområde som detta och en ljuskälla som den ovan borde kräva en kraftig effekt för att vara så stark,  men det ligger också ett par skolor i området som kan räknas till större förbrukare.

Är det någon som har en aning om vad det var vi såg upptänt här i lördags natt dvs natten till söndagen den 24/5 2009?
