Losing my Sense of Taste for a Day

Last week something strange happened to me. After eating loads of Wasabi and Chili, I woke up the next day without any taste from my tongue.

I realized while having my breakfast because the chocolate syrup didn't taste as sweet as usual. It still took some time until I fully recognized my loss of taste.

So if you ever wondered how chocolate tastes when you can't taste, I can tell you it's boring. And because I lost all my other taste senses, it didn't taste bitter either, just like an tasteless paste.

The good part about chocolate is that it has a very good smell, so smelling it makes you remember what it tastes like, so you imagine the taste. This does not work with salt for example. I tried a little bit with the tip of my tongue. Normally it's quite intense when tasted pure, but for me it had less taste than a few grains of sand.

For lunch I had salad with many ingredients. Again, I know what most things taste like, so I imagined the taste and really thought I had little bit of my sensuality back. But I rather blame my memory for that, again.

The evening was even worse. I had potato wedges with tomato ketchup. If I didn't know ketchup before, I would be wondering why people love this viscid cream so much. At least it had a slightly sour taste when swallowing. And that taste came from my palate. I didn't know you can taste with the roof of your mouth... but it's true.

I better skip the part about how beer tastes without a taste, and even water tastes horrible without any sense of taste. Yeah, not tasting has some kind of anti-taste. Probably water has some taste that cancels out this anti-taste to taste neutral... who knows.

Luckily, the next day I slowly regained all my senses and now this temporal disability has vanished. But it left some great impressions on me and I want to summarize those for you:

• You judge a lot about food by it's smell and your imagination about how it could taste.
• You only fully realize how wonderful the sense of taste can be when you lose it
• Never eat too much of Wasabi unless you intend to have the same experience I had :-)

Focal Length Calculation for a DSLR Camera

As I'm studying for a subject concerning cameras at university, I have to used a formula for calculating the required focal length to fill the sensor with an image. And I thought this formula could be quite practical for you as well.

That formula is

f = d * I / (I + O)

where f[m] denotes the required focal length to picture an image with the width of O[m] on the sensor with the width of I[m] when the object is d[m] away from the camera.

For my Canon EOS 400D camera with a sensor dimension of 22.2mm x 14.8mm a sample calculation could look like this:

I would like to picture an object that is 20cm wide and 1m away from my camera. So I set d = 1m, O = 0.02m and I = 0.0148m (sensor width).
Inserting into the formula from above this gives me a focal length of f=0.0689m or 69mm.

This formula is valid for all cameras (just find out your sensor dimensions) and all lenses.

My home grown chilies start to grow bigger and bigger, the first are bright red already. Soon others will follow. I'm planning to sell some of them on eBay as I can't handle the huge amount of them on my own.
So in case you want to try some or grow them yourself, just mail me and I can send you some exemplars.

Software Update for Nokia 5310 Version 5.81

Today I updated my Nokia 5310 phone to the new 5.81 version. As I have read that there may be some problems with it I thought I'd report about my experience on my blog.

To find out what version is installed on your phone, type in *#0000# using your keypad. I had the 3.6 version installed. So I downloaded the latest version of the Nokia Software Updater. After a reboot it detected my phone connected via the USB cable.
I took the hint to backup the phone settings seriously. You can do that via the phone menu. Go to the Setting->Sync and backup->Create Backup submenu.

Then I started the update which ran automatically without problems. 10 minutes later the phone rebooted and requested the PIN code. Unfortunately all my personal data were deleted. So I had to restore the data I backed up before. That worked quite fine and I didn't loose any contact info or calendar settings.

What's new?
So far I found the following new options and functionalities:

• I can now add Java programs to my favorite's list.


• There is now a quick dial function. Just press one of the keys from 2 to 9 for 2 seconds.

Update: The newest version is V 09.42 which can be installed just as easy. I haven't found any major improvements yet (except for a new status bar when loading things).

Cokin Filter System on my Canon EOS 400D

My newest purchase for my Canon EOS 400D camera is a part of the Cokin Filter System. It basically consists of a filter holder and an adapter for 58mm lenses. The filter holder can hold a variety of filters. The set I got from eBay consisted of 7 filters including stars, blue color, pastel and others.
Later, I bought a much desired gradient filter and closeup lens (+3). Compared to the price of individual screw in filters, Cokin filters only cost a fraction if you buy them on the used market as most of them only consist of a glass plate with some printing on it.
I'd like to give you a review of the filters I have got. It may help you decide if you want to buy the same for your digital or analog camera. I will continue this list as I gain more experience and probably more filters.

Diffractor Galaxy (42)
This is a very odd filter that adds rainbow like beams to point light sources. The effect is rather strong and I think it destroys more of the image than adds to it.

Star 4 (57 A)
This filter adds nice star effects to your image. You can rotate it and use it for point light sources like street lamps at night.

Parallel (58)
This works similar like the star filter but only creates stars with two beams of light. You can also use it for point light sources like this image.

Spot-Orange (66)
This is an orange glass with a transparent circle in the middle. I have not found suitable scenes where to use it yet.

Coef. + 2 BLUE (80 A)
This is a blue filter that makes the colors the image. I made some wonderful images with a cloudy sky.

Pastel 2 (87)
This filter makes the picture look much smoother, almost like a painting. I found it best for closeups and the effect destroys the image on wide angle scenes. But for flower pictures it really adds a lot to the image.

Close-up +3 (103 A)
This is a classic closeup filter that allows you to move your camera closer to objects.

Gradual G1 Grey (120 A)
This filter is a gradual gray filter. You can use it to make the sky darker than the foreground which helps you a lot when it comes to correct exposure in high contrast outdoor scenes. You could do this effect on your computer when shooting in RAW but for JPEG images you get best quality when using this filter. The filter is color neutral and you can rotate the filter holder to adjust the effect.

Reviving an old Eumig R 2000 projector

A few weeks ago I was carrying out the waste when I found something strange in the waste room. First it looked like a television, but when I took a closer look it turned out to be something different. It was a 8mm film projector.

I couldn't resist taking it into my flat and take a closer look. I plugged it into the power plug and turned it on. The lamp was still working and a motor was transporting the non-existent film. But there was some flickering on it's screen.

It must have stood somewhere for ages, so it was quite dusty. I started cleaning it and also opened it's case. It was quite a surprise when I found out that you can flip it's mirror outwards so you can watch movies on both the internal screen as well as the projection on a wall. The only thing it didn't have was sound.

As soon as this day I ordered a 8mm movie on eBay, the cheapest I could find as I just wanted to try it out. A week later I had the movie.

But how to get the movie into the projector? I failed feeding it at first. So I thought: "Maybe I need to rewind it". So I transfered the movie onto another film roll and tried again. I had quite some troubles getting the film through all the rolls and gears inside the projector. But finally I succeeded and had to find out: the movie was upside down. So maybe it was all right the way it was before. I retransfered it to the original film roll and tried another time. This time the projector accepted it and started showing the pictures on the screen. Hurray!!!

Later that day me and my girlfriend made ourselves a movie evening with 5 minutes of film. It was the Max and Moritz movie, part 1. As the projector is a silent one, we played a Ennio Morricone CD in the background. What an amazing experience for a guy who grew up knowing the television only.

As I never intended to watch movies on this device, I had the idea to sell it on eBay later on. But before I did, I came to a flea market and started talking to a dealer there. He said, that a few minutes earlier a guy wanted to buy a projector like mine. Before he could write down my number, that guy came back and I talked to him directly.

A week later that same guy came to visit my flat and took a look at the projector. And he actually bought it. So I sold my projector which didn't cost me anything.

Summing up I avoided that the projector would have been disposed in an inappropriate way, I had some fun playing around with it and I made some money selling it. I wish things like that would happen more often to me.
