XP Again ?

A09A7600It’s not right.  The HP laptop, which I’ve been using for net connection, suddenly died. In the righteousness of the eastern heaven’s standard, such unfairness shouldn’t be happened to such nice man like me !  😀   Theoretically, I can still check Email or my blog using my phone though I wouldn’t do such awkward work.  HP seemed to be hopeless. Even worse, it’s on Sunday = no help. My friend in the WW workshop texted me “It will be saved” though, I can’t wait till Wednesday meeting.  With a kind of last moment struggle, I tried to revive long dead Toshiba with XP on it. —– Basically, this one is working except the connection to the net. (MS said, that they can’t configure) THEN, if MS said so, how about IntelPROSet Wireless ? = Oh !  It’s works.  Then configure its connection with the router password etc etc. (so-called tinkering = and update many program)   😀

It was a funny situation.  Window was saying that they no longer support, still they supply some update for XP.   In this way, I managed to access my Email and a lots of lots of trouble, reached to my blog (this one) —- still, in a certain extent it IS working !

A09A7606So, somewhat sneaked out the trouble, and while thinking whether HP could be repaired or not or buy new one —– I’m testing this one (= TOSHIBA saved from a scrapyard) to upload a new post. (while finding out loads of mismatch.  😀  )

Still it’s a fun !   Honest.

Autumn Color

Fall Color(1)-DSC07415

Those photos were taken by a single glass homemade lens, called Gaudy Lens on Sony A7R Camera —– you may wonder why needed to use High spec’ camera = the matter was not the spec’ but its small size.   😀

This last photo was by the Mag’ Lens, not by Gaudy Lens —– any way looks the same = doesn’t matter.  As those both lenses got a lots of halation, picture never looks sharp.    Yes that’s what I wanted. = I just wanted atmosphere, or Impression.   In that requirment, those lenses are doing good job.   😀

Moth

Moss(1)--001

(It seemed, those photos were the color comparison sample of the lenses.  Left was taken by a current Canon EF macro but the right was taken by a lens from a Kodak Instamatic mounted on an aluminium can in reverse direction. — See next photos)

The old lens for a film may be adjusted to the color compensation on the print making then.

Moss(2)-Instamatic-006

Monstrous home-made lens is still working as a macro lens though, not very easy to use (Very dark with x6 magnification = you don’t know where you are watching)  —– Yet still, think the cost = don’t ask too much.   😀 

The small moth parched on a washing-up sponge must be a survivor (or, could she be the one waiting next spring ? — I’m not sure)

Ultra sonic / Silent wave Motor

Ceramic-USM Motor-000

(On the photo, round comb like structure is the motor (OD = 12 mm) = its teeth of a comb or the legs of a milliped moves like milliped legs and make the silver-colored disc to move / rotate = that’s how this motor works ! —– though, in real life, you can’t see its teeth or legs move = the each movement is too small to see = so, quietly just the disc moves —– looks spooky !)

 Ultra sonic or Silent wave, what so ever called, the ceramic motor using vibration of its material is rather new kind of the device though, the vibration of the ceramic material itself has been known long time. = the most common use around our life is THAT sounding disc in the security device or even a small round disc in a Singing Christmas card. 

Still, to use its vibration to a motor was happened as an accidental discovery = a ceramic unit on a desk moved while under a test.  So, the engineer got an idea, why not to make a motor and if the sound is too noisy, why not make it to an inaudible high frequency (to an ultrasonic) = So, Ultrasonic motor was developed.  With the manufacturer’s sales tactics, you might be made to believe that the Ultrasonic Motor is an exclusive expensive device. —– you are wrong. 

The top photo is showing a sample, a Silent wave Motor from Nikon’s 18~200 mm Zoom lens.   You may find the similar motor from China in the net, less than few pound. ( Though, if you got a skill to use it include the design and make of the whole gear train, I’ll admire you ! = Utilise whole mechanism as a drive unit, would be far easier, and an electronic controller is on the net as well  )   Yet still to the Nikon, to design the AF drive mechanism, using a traditional DC-motor or use a Silent wave Motor (USM) was not a hard choice = in the cost term, it would be more or less the same. ( DC-motor needs more gears and may have noise problem — mechanically USM needs less gear (= cheaper and easier to assemble) but electronically more complicated work in the program.  (Basically, USM needs the pulse train to drive = two different pulses, one is a bit ahead of the others and which one goes ahead determine the direction of the rotation = in photo term, move focus to far or closer.) ( On the top photo, you may see a flex circuit come out from the USM which got four gold contacts = two each of pulse input ) 

Since the camera’s video function becoming more important, the quietness of the camera (especially its AF motor) became heavy issue, —– So, Canon introduced STM ( = quieter Stepper motor) —– in the traditional sense, stepper motor was driven by the electric pulse, which sharp on-off square wave pulse couldn’t be smooth and quieter, yet Canon seemed to be adapted the use of PMW drive (the voltage of the each pulse gradually rise) instead of the simple square wave ! —– Though, my Canon 40 mm F2.8 Pancake lens got such STM motor — It’s far from quiet. —– in comparison, the SONY lenses (which I have no information of what kind of motor) = are amazingly quiet. ( = what kind of motor inside ? )   So far, there was no broken SONY lens in a junk-box of a camera shop = I haven’t cut-open them yet.   😀

Sakura-mochi (Japanese Cherry cake)

Sakura-mochi(1)-DSC07142Sakura-mochi (桜餅) is a common Japanese sweets.  You can buy it from any Japanese sweets shop.  It is not a kind of very complicated cooking still not many people ever attempt to make it by themselves.  (May be to make Ohagi / Botamoch could be the farthest people does.)    Many years I’ve been thinking “Why shouldn’t I make it” and “I want to eat — I haven’t eaten it more than 30 years”

So, this is my attempt to make it though, I never seen how it was made neither my mother told me how.  Therefore, all I’m showing here were done by the sheer guess-work and I wouldn’t claim any authenticity in a Japanese sweet making tradition or any suggestion pretending any kind of wise man.

Sakura-mochi(2)-000From the improvised idea of Rice-cake making,  I used White Rice powder and Glutinous Rice powder half and half, because if it was pure glutinous rice it may become too sticky. (Photo left)  So, I mixed one large spoonful of each powder and one small spoonful of sugar with 3 and half large spoonful water. (Photo middle) then put a half runny mix to a dish and Micro-waved (Mid-High, 1.5 to 2 minutes)
So, the Photo left was the cooked skin of the cake. —– carefully peel it off and use it to wrap up the Anko (Sweet Red bean paste) (Photo middle) —– Then wrap the whole cake with salt pickled Cherry leaf. (Photo Right)
Sakura-mochi(4)-DSC07152Voila, here it is.  Japanese Sakura-moch.  —– Looks genuine ! (isn’t it ?) —– The taste was genuine (what else could it be !) —– (If I could steam the finished whole cake, the flavor of the Cherry leaf would have gone into the cake more.)    Considering this is the first ever attempt in my  life (in fact, I did one test run before Photo shooting) = the result wasn’t too bad.  “Well done Yoshizen” (eat two Sakura-moch made a man Fully satisfied !   😀  )  

Incidentally, the Cherry leaf was meant to give nice flavour and a looks good wrapping, and not meant to be eaten. (I hope, you didn’t try eat it with struggle. 😀 ) There is other variation of this = Kashiwa-moch (柏餅), which use an Acorn like Kashiwa’s leaf for wrapping though I couldn’t find that tree in this country.    Kashiwa-mochi was meant to be eaten on the day of the Boy’s festival (端午の節句) = 5th of May.   And the Sakura-moch was originally for the Girl’s festival (桃の節句)    (I guess) though, it became so popular, you can find them all year-long. (Nothing wrong with it.  🙂  )

**********

PS : While giving a thought, I realized that the Kashiwa-moch must be invented first.    When you play in a Shinto shrine, you clap the hand = it called Kashiwade  (柏手).   The leaf of the tree Kashiwa has a shape of a hand, hence the hand spread the fingers was called Kashiwade, and the Kashiwade is a symbol of the honest, single-minded clean person (think it in comparison to a gripped hand which could hold a weapon and next moment it could hit you).  So, a boy’s parents wish their boy grow to a strong honest man and think the things associated with Kashiwa is auspicious.

—– So, a clever owner of the sweet shop (和菓子屋) invented a sweet wrapped in a Kashiwa leaf = Kashiwa-mochi and sold for the boy’s day’s celebration.   It must be a big hit, then they thought, if there is a sweet for boys, why not for girls as well = then Sakura-moch was made.   🙂

Oleander

This is a tree flower which I have deep attachment, hence I want to see more here = though, strangely she was not planted often.  Probably because people afraid of the poison of this plant.   In deed, if you feed the handful leaves to the animal (cow or goat kind) the animal would die easily = strange contradiction is, its poison (Oleandrin) has very similar effect to the poison of Foxglove (Digitalis / Digitoxin = Very strong stimulant and or poison to the heart) —– yet you can see the Foxglove everywhere even though Foxglove can kill you too.
Oleander(2)-001The reason why I feel such attachment to this flower was, she was associated with some poets who I respect, — and its poisonous nature.    When I was small, my hero was the Ninja or humanoid Robot, not a Superman kind of American comic fantasy.  So, we kids practiced how to make a rope to climb a wall or the formula to make a poison.  (still, I never heard of any accident with those poisons = Japanese got necessary knowledges —– idiot can’t be a Ninja = we kids wanted to master the real skill, not dreaming in a silly fantasy to fly a sky.)

Very remarkable fact of this plant, Nerium Oleander (夾竹桃、キョウチクトウ)is, that this plant has the will and the ability to survive while eliminating other plant with its poison.  Oleander was the plant first revived and flowered on the literally scorched ground of the Hiroshima, after that atomic bomb.   Hence, she was named and honoured as the Flower of the Hiroshima. —– (Hidden message here might not be a flowering peace but a kept poison / we never forget.)

(Those photos were taken by a homemade lens nicknamed “koda-fun lens” with or without extension ring.)

Remove the reflection

Reflection(10)-DSC06933After I published the post “Instamatic Macro” I received a mail asking me how I could manage to eliminate the reflection inside of the shiny Macro Tube.   The man was a reader who read my old post “ Tiny Life ” long time ago and in fact, he made the same Macro adapter using similar aluminium can, but having the trouble from the internal reflection. 

(He said that he splayed the inside with a Mat Black Splay Paint though, even with such paint, the surface was pretty smooth and making rather high reflection which is ruining the image.)  On top of the smooth surface, the inside of the round pipe acting like a converging mirror, making a hot bright-spot in the center of the image.  (Hence, its reflection created the images in the previous Post —– though, those photos were the exaggerated reflection from a shiny metal pipe, not from the real macro tube.   😀 )

Reflection(11)-DSC06943There are the several method to eliminate the internal reflection = Applying a good Black Velvet is the one, though to glue-up a soft cloth inside of a small can is a very awkward task.   ( I can guaranty you struggle — I know, as I did it before.   😀  )     Proper design will put the proper light barrier discs, though, to insert the full-size disc need to have a full opening of the pipe-end.   Bend and insert a semi-flexible disc (ring) and make it stand in the position is the other way.   (Still, not easy though.)

Reflection(12)-000—– What I did was, to insert a paper spiral inside.   I made a spiral using a semi-soft (stiffer than drawing paper) = (First, made the 3 paper rings which got 2 mm larger  diameter of the can’s internal diameter— then cut and connect them to make a spiral) Then this spiral was slipped inside of the can.  (It needs a good rotating manoeuvre ! ) (I made a paper tool to catch and move the spiral = Photo left.  And how to use it = Photo right.)  —– when the spiral settled in the good position where all the reflection and the glare was shielded, fix the position using a glue.  = Job done !   (for the clarity sake, in the photos, the edge of the spiral has not been painted black. —– I hope, you can see how to work-out this game.)

************

PS : For an educational purpose,  I’ll show you the scene behind. Reflection(13)-000Photo left was the same mosquito but without having a reflection eliminated.      And the photo right was how the spiral inside of the macro tube looks like.

Reflectgraphy

Those images were the products of which I didn’t intend or a by-product occurred in the other process.

You will see what I was doing on the next post.







Half of the Photography said to be made just by chance encounter — may be true.  😀

Instamatic Macro

Instamatic Macro(1)-DSC06872

Well, as I suggested in the previous post that  25 mm lens of 110 Instamatic camera is suited for macro use = So, I made a lens.

Instamatic Macro(2)-006

No doubt, this must be the most funny looking lens among my homemade lenses, since the material I used was a water bottle for bicycle.  (No problem, it only costed me £1)   The lens was fixed on the cap in the reversed direction, and with its about 17 cm extension, its makes about x6 magnification of the image.

Instamatic Macro(3)-000

Photo left was  a dead mosquito I found in the kitchen.    I’m not happy with its bit blurry image (available light with 1/3 sec exposure —– at moment I’m not using my Sony with flash light = no synchro-socket, nor adapter) —– anyhow, I need to go out to see something small insects or a kind.  (Photography is a kind of life live on the leg. = You can’t do it while sitting.)   😀
