Make LED Ring Light

While hiding in my cave (:-D ) I found the time to do building work (Since, as

I don’t have a habit to watch TV (I don’t have a TV 

nor able for streaming video signal on USB dongle 

connection) or DVD,I have to DO something 😀 ).

From other project where I changed White LED to 

Color LED I got mountain of White LED, I decided

to make LED Ring Light which can utilize

those LEDs in number.

Ring Light can create (almost) shadowless  

image, or having faint shadow surrounding the  

subjects, some says, it is the Holy Grail in the Lighting effect. 🙂

[]

Funny situation these days is, we can get the LEDs from the products,  

such as an LED Work Light from Lidl which is using 40, 60 LEDs inside,

as cheap as £15 = much much cheaper than to buy LED itself from an

electronic supplier = hence disassemble and use them to make such as

a Ring Light can save a cost a lot. (advantage is, that the LEDs has been

selected and tested already by the maker and the Lidl, hence there is little

chance to get old type dead-stock from unknown supplier in the Net  🙂 )

[]

Basically, all about LED Ring Light is “How to mount a ring around the

lens front” — other than this, everything else are straight forward =

just put a lots of LEDs and connect it to the battery.

—– Sound easy though, the trouble is, not like in a good old days when

most of the lenses from one camera maker has only one or few filter sizes

(such as for Pentax = 49mm, Nikon = 52mm, Canon = 58mm etc), but

now as the role of filter is diminishing (now most of the visual effects were

created by Photoshop), lens doesn’t need to have the same filter size =

in the other words, to make a ring light capable to be used on many lenses

is nothing but a headache. 🙂

To make the situation even worse is, the use of Zoom lens is the norm now

and as the lens starts from wide-angle, it is necessary to make ring light NOT

vignettes (not cut off the corner of the image by the additional protruded edge)

= it got to be much larger than a front element of the lens.

On the other hand, some lenses especially on the smaller camera is getting

even smaller and many of them has even no filter thread on the front at all.

= it mean, the ring light got to be designed and made for the individual purpose

and the choice of lens. —– (hence, better to do DIY 🙂 )

[]

I decided to make one for my 100mm macro and other for 24mm~70mm Zoom.

So that the first sample here is to make it for my Canon 100mm F2.8 Macro (not 

the latest L type — it came to the market only two months later, but this one is

pretty sharp as well, and I like its smaller front lens which would cast less shadow

when we close to the subject and easier to give a lighting.

(in extreme close-up, large front lens allows only side-lighting. 

And I don’t see much of help from the so-called Image-stabilizer = if it helps two

or three stops, why not just set higher ISO speed.  And having very delicate lens

shifting mechanism which is suspending the lens element in the air by the

magnetic coils or ceramic motors, it would make the lens even more sensitive to

the shock.  🙂 )

[A ring to mount the LEDs can be made from a Phenol plastic board with copper

track for electronic circuit, to even just a card-board paper (if it is just for an

experiments, 1 mm thick card-board paper would be good enough) or to mount

the LED from the the back (through a hole) = Art-mounting-board is a good choice.

(Still, precisely drilling 30, 40 holes, this work needs to have a good Zen mind.)  😀

Which ever the material, you need to find the diameter of the ring and cut the

material.  ( I think the photos here are self-explanatory. )

Use caliper to find the diameter under the bayonet to mount lens hood. 

If no caliper in hand, use right-angled paper.

Then draw the circles of its mounting diameter.  I’m using a sharpened needle

mounted on the compass to cut the paper as well.  And cut the Phenol plastic

board, I’ve clumped a cutting blade on the compass.

A paper ring cutted with diameter of the lens  and outer diameter was placed

under the bayonet and the shape of it was taken.   (To place this paper ring /

template, under the lens bayonet, the ring needs to cut on one place to open)

Then the shape of the ring and the bayonet craw was copied on the card-board paper. 

( On the card board paper, two additional circles has to be drawn, + 6 mm larger

than inside diameter and  + 8.5 mm ) — To plot the position to put LED, divide 

+ 8.5 mm circle to 8.  Then, within a semi-circle of 1/8, find equidistant point to

put LEDs — In my case every 11 mm and the holes to insert LEDs are pierced

(Photo above middle)  If you put too few LED you will have ugly multiple shadow,

or if you put too many, the battery will run-out rather soon.  It is a compromise.

(sort of the standard is, put the LED at every 8~12 mm distance )

In this design, I’m connecting all the

LEDs in parallel, and you can see

the different way to connecting them.

Left Top = if the LED came from

another device and having already

trimmed leg, you have to make sure

to insert all of them keeping the same 

direction (inside of LED you will see

narrower pin (+) and the broader pin (-),

you have to insert LED all in the same orientation, say (+) = outside of the ring.

And connect them using a wire such as from telephone cable (better polish it 

before soldering) by running it inside and outside of the LED leg alternative way.

Then you will have two wire ring on the board.

Photo Middle = If you got newly bought LEDs (assuming all of them are having 

the same color and the brightness — some are more blueish 🙂 = the cheaper you

pay, you will have headache — To insert LED’s to the board keep longer leg (+)

outside, then you just bend each leg to touch next LED and cut excess, then

solder each leg next by next = you will get two wire ring on the board.

Photo bottom = If you don’t have soldering facility yourself, and no one to ask, 

don’t worry still you can do !  = Insert all the LED to the board (such as photo

above) always keeping longer leg outside, then bend the leg towards the next

LED and twist the leg wire to next one. Then bend next one’s leg to third LED’s

leg and so on (connect last one’s leg to the first one, need to insert the leg-wire

to the gap between the board. = you needs to have a bit of work.

Use a narrow-headed pliers or tweezers would be a good help.

When you got the board, with all the LEDs were connected together, then

connect the power wire to each wire ring —> and connect to the 4xAA battery

through 2.2~10 ohm 1W register. (this is the MUST ) = If LEDs weren’t light up,

connect the battery other way round. (Change polarity )   2.2 ohm register will

give you brighter light but shorten the battery life = 20~30 LEDs will drain the

power nearly 1 A from 4xAA battery it would last less than 1 hour, but with

10 ohm, it would not be as bright though, in an intermittent use, your battery will

last much longer = it’s depend on how you are going to use it. (Put a switch to

select High and Low would be an good idea).

( The register may get hot though it is normal = pay attention to the layout and

the design for this heat problem.)

(For serious video shooting, use 2.2 ohm and 4xD battery, and make others envy.)

If only a part of the ring was lighten up, it is the point where your connection was

loose = check the connection and tighten it up. If one or two LEDs were not

lighten up, it’s mean that LED was dead and needs to replace (it’s an awkward job

= it’s better to check all the LED before hand ).

Then, fix the power cable to the ring, tie it with strong thread like the photo above

right, or use heat-gun glue.  (I’ve covered the end of the cable with heat-shrink

tube for better protection)

When everything went well, end result should looks like this.

= Voila, LED Ring Light !

(In fact, I’ve used paper one for a template to make it on a Phenol plastic

circuit board.) —– Further to this, such as where to keep or mount a

battery case is largely depend on you.

And I’ll show you my final product in the coming post.

Self Healing ? ! ! !

As I wrote on the previous post, I got injury and

the wounds were stitched and patched up.

This is the heaviest injury on my life.   As I used to climb the

mountain, also worked as a voluntary keeper of a mountain

shelter while cutting 10 tons of fallen tree for fire wood every

summer, and a kind of man likes to make everything, using all

sorts of sometime very sharp tools, yet I didn’t get injured.

(Though, in such environment, small cut etc is not rare at all.

In fact I cut my finger first time when I was 4 years old = first

time ever I touched a sharp knife and the finger is still carrying that scar.

= It’s mean, I’m a regular user of a plaster tape.  In fact, Plaster tape , Antiseptic cream and

Tiger balm are the all medicine I got here = nothing else.  🙂 )

(Photo of the Zombie might be up-loaded above, later  😀  😀 )

[]

For a small cut or pierced skin, just clean the area and cover-up = may be 3~4 days, it will be healed.

(You believe, or want to believe or not, I discovered, Super Glue can close the cut and good

to cover the wounds too. —– You may try  😀  —– As a matter of fact, one type of 

Cyanoacrylate = Super Glue which will be dissolved by the water in the body, has been used for

surgical operation = doesn’t need to remove like surgical thread ) —– After all, healing is what our

body is doing, not the treatment itself.  Treatment is to remove the destructive cause, such as lodged

objects or dirt or already dead part of the body, then leave the healing business to the body’s

own mechanism = with small encouragement of stimulant to increase blood circulation or prevent

further infection by using Antiseptic or Antibiotics, wound would be healed by itself.

—– (I’m talking about physical light injury on the skin.  To inject additional metabolic substance

for the body to regain its balance etc, kind of the internal matters are out of the scope here).

[]

If we don’t cover the wound, it will be covered by the dried up blood or bodily fluid to become

so-called Scab and under this natural cover, healing process is taking place. = In other

words we may not need to put plaster tape though, during the work, the same injured part may be

rubbed against other object etc and start bleeding again = it is better to cover up.

Still, this Scab seems to be the best protection than a plaster tape. Plaster tape keeps

the wound moist and the scared skin cell were exposed inside, hence bacteria can get in and

the infection would takes place = then the pus would be oozing out. = this infection would prolong

the healing process though, it is a necessary evil 🙂

If you observe the scar covered by scab, it pulling the skin around, hence when it was cured the

scar is more visible. Wet cure show less scar. —– any how, it’s a small patch on the skin. 🙂

[]

It seems the scab made by the bodily-fluid which got anti-septic property, and it can keep the

wound in just right condition = germ-free and able to keep injured, exposed skin tissue in

exact right humidity. = Hard enough to be a protective shield and able to keep inside germ free,

yet able to evaporate excess moisture. —– I don’t know, is there any artificial material can do this.

Scab on the injured skin is not a kind of welcomed guest though, they are so well designed (or well

refined during the history of the evolution of the life), we should pay respect to the Nature =

or Buddhists should say the Dharma. (=Whole system of the Nature and its Rules)

Without having this badly perceived, badly named Scab any animal include us

even the plants (their bleeding sap = bodily fluid such as Rubber plant’s is not for

us to make Car-tire but to seal the wound) couldn’t survive till today. Otherwise

all the animal and the plants had been infected and eradicated by the bacteria.

[]

Having more than inch of stitched dark scar on the forehead, I didn’t like to have dark scab on

my nose and the cheek bone hence, I’m under the patched up state. 

= Not very pretty sight in deed 😀   So, I’ve been inside all day (in fact this is the second day)

—– only the trouble is the egg and the onion has run-out — M m m ?

Should I go out shopping pretending “Frankenstein here” or walk like “Zombie” to scare local kids,

and giving them an opportunity to enjoy a nightmare or two ?   Ha ha ha 😀

It isn’t like a “Good Peaceful Buddhist” is it ? —– Otherwise settle with humble meal ?

Good question 😀

Smashed Camera and the Face !

Only yesterday, I managed to stumble on a curb stone and smashed myself on a concrete

car-park.—– Unfortunately, my camera was on my shoulder hence,

the camera was smashed too.

 

I was landed on the concrete, over my specks apparently fallen before me, hence one of the lens

cut into my forehead.  I was amburanced to a hospital and my face was stitched and patched up. 🙂

The hospital’s handling of my case was what we know well = I was left waited more than two hours

still bleeding yet just sitting on a bench. (While waiting, blood pressure etc were taken by nurses)

Then I noticed, despite of my camera being smashed and the view screen was shuttered, yet

amazingly it was still functioning, even more of my amazement, a Zoom lens fitted on the camera

= Canon’s 8~15 mm F4 Fish-eye lens was still working perfect ! ! !

(with its fragile movable structure, Zoom lens couldn’t survive this kind of shock = this is the

exceptional case !  = May be Canon designed it for the photographers with rough

and tumble in mind 😀  = Anyhow it was a good news in a bad situation 🙂

ERA[]

On my life, I don’t have accident or should I say only seldom = On the Ski, I’ve

broken 3 Skies but never broken any bone or heavily cut myself.

On the climbing, I’ve fallen 10m and about 5m —– still always landed on my rucksack hence never

injured. (other small falls were the nature in the climb 😀 ) Therefore, I had no experience of the

hospital, except the one when I was attacked and hospitalized in 24 hours coma and woke-up there.

So that this occasion was a rare chance to observe all the people involved = local people who saw me

fall was very kind and as he saw the gushed blood, called the ambulance at once.

The ambulance people were very professional (got to be) and I was taken to the hospital in 5 min

drive. —– (then long long waiting started while seeing another patient such as a lady mugged and

injured and so on) —– on the end, the Nurse and the Doctor did very good job to find out the

broken glasses in the cut (down to the skull !) and stitched it up.

—– And, I walked back 15 min to my place in the middle of night = 7 hours after the accident.

[]

As far as I know, the Zen mind should have an Hyper Vision in such case = when I fell

on the rock, I saw the slow moving details of the rock and the surrounding view.

When my ski caught the tree under the snow and my body was flying forward in the air,

I saw my body in a slow-motion. —– though, in this occasion, I only found myself laying on

the ground = there was a kind of lapse of the time = it seemed to have a jump of memory.

—– Why I couldn’t have seen my falling body nor able to take Ukemi (受身 / Safer

bodily movement to reduce the impact when falling to the ground).

(Bruise on both of my back hands indicates that the hands instinctively moved to protect myself

though, why didn’t hit the ground palm first, as an Ukemi.  ? ) = May be, the Hyper Vision could

have happened only the moment when the Mind was in a fully alerted state, not in an

absent minded casual situation = after 30 years, I still have a moment of absent-minded or lapse

of my mindfulness. —– Or, I must be getting old and getting rotten. 😀

It’s mean, should I look for the protective gear of mountain biker or even a walking frame ?

(May be not a coffin yet)    Ha ha ha 😀

LED Lighting in Photography

In most of the case and for most of the people, Photography starts when the subject

was found to be there. = Has found mean [It was seen] = it’s mean [There was a light]

= if it was in a total darkness, we couldn’t see = we don’t notice its existence,

hence no photography.

Though, more of the often, photographer need to take picture because the subject was still

known to be there = it could be a nocturnal animal or cave paintings —– when I needed to take

picture of French wine cellars, it was a challenge. = It has to be clearly visible in the photo, yet to be

seen as a deep dark cellar = what a contradiction especially all the bottles were covered

with black fluffy fungi. 😀

[]

Modern Hi-Tech Camera seemed to be able to see better than our eyes though, it’s light measuring

capability is still only down to EV-o or -1 or so but  Auto Focus doesn’t necessary work under such

dim light. (Hence, Focus-assist-light in the Flash-light or so-called Active Focus System using

projected LED light).

But when the photography has gone outside of “expected scenario” of the use of camera, such as

[Pinhole photo] or use another lens for higher close-up magnification, lords of troubles comes in.

Equivalent F-aperture of Pinhole = F-125 (think, keep stopping-down F-22 to 32, 45, 64, 90

then to 125) or F-250 is far beyond of what camera can handle.—– Or, use a lens in reverse to

have x5 magnification, the image become too dark to see in the view finder

= additional strong light become necessary.

[]

Thanks to the easiness to use LED, which doesn’t heat-up the subject like as Halogen-light does,

I’ve been using them as a focus-light or even to take picture. = Use one or some LED to make a

focus-light is very easy such as seen in the another post [Tiny Life] (link here) —– it is just a

matter to connect LED to a power, normally to the battery(s), normally series with

small register. (I’m going to write about those “Technical” details in the next post) but an

easiest way is to utilize ordinary LED Torch-Lamp or even a USB Keyboard light which you can

find in a Pound-shop.  🙂

[]

Here some sample demonstration (of simple adaptation or simple “mod” work 😀 )

This is a little adaptation of a 1W LED Torch-Lamp (This one need only 2xAA battery !

= I’ll talk about a significance of 2xAA battery in the next post) —– in order to mount the lamp

to a stand, a piece of C-channel was drilled and 1/4” screw was tapped.

Use it as a spot light or diffused light etc is just up to your imagination.

And this is a way to use USB light.  = USB sockets were fixed and soldered to a piece of

circuit-board and they were connected to an 4xAA battery holder which acts as a stand as well.

One light has only one LED hence used as a spot-light and other has line of 5 LEDs hence covering

it with tissue-paper, it can be used as a diffused-light.

—– USB light was designed to be used on USB socket though, as long as it was

connected to 5V it will light up. (4×1.5V battery may give, up to 6V on the beginning though,

it wouldn’t destroy the LED, and even if you connected wrong polarity, it wouldn’t destroy them

neither, simply it wouldn’t light up = connect other-way round to make it light)

USB connector has 4 pins, of which both outside pins are carrying 5V supply.  You may find which

is + with multiple-tester though,  in this LED light case, JUST Connect = if it’s light = It’s right. 😀

Female USB socket can be taken out from Multiple USB Port which you can buy from £1 shop

= it’s much cheaper than to buy socket itself.  😀

If you don’t have soldering-iron and such skill, just smash open the USB plug = you

may find 2 wires in the spiral tube = fix the spiral tube with wire or what-so-ever the

manner and connect each wire to the battery + and – = if it doesn’t light-up,

change polarity.

(If you want to place the USB light on the camera, best way is to use camera bracket and fix the

spiral tube to the bracket and the cables can be extended to the battery holder.

(1m, 2m of wire wouldn’t make noticeable change of the brightness of LED)

[]

If you are interested in = just try.

You may realized how easy it is, and fun to experiment with mini photo-studio !

San-sai (山菜) = Edible Plants from Mountain

Early summer, lots of Japanese goes out field or mountain to gather edible plants.

They appreciates each plant’s distinctive tastes and the flavor which is unique to the season.

= Naturally, I receive my friends Email with those stories and photographs (Link here).  (He was few years

Younger member of the Alpine Club = In his older Posts, you may see that he is climbing snowy mountain

every week and skiing ! = That’s how Japanese is living with the Nature )

[]

—– those custom was behind of my Bracken story. = for me, as an ex-patriot, it is a sort of nostalgia to my

Japanese taste,  in the same time it is a resistance to the modern western culture “Vegetable comes

from Tesco”, —– but in fact, it often came from a farm other-side of the earth, 

and regardless the time of year.  (Still, I got tasteful great memory to eat full-ripen tomato in the

very middle of dizzyingly vast, red tomato field in a Canary Island which tomato is destined to

a shelf of super market in England.  A farmer stopped me to pick, and gave me the better one  😀 )

For a sake of convenience, it degrading the one’s only life to a life in statistical number.

To live in its moment mean = unique moment = unique to its year’s season. = not standardized

homogeneous pattern, which was mass produced and sold by a Supermarket.

[]

The stories from Japan is not a kind of surprising news = went so and so place and picked this and that plants then

enjoyed eating them as a Templa and so-on.

(In the photo left, underneath is Wasabia Japonica (that Wasabi /山葵 , comes with Sushi.

They grow in a very clean mountain stream).    And the Small Bamboo Shoots (Takenoko / 竹の子 ).

The big one on top is Aralia Cordata (Udo / 独活).

Right photo is also in the Araliaceae family, Eleutherococcus Sciaphylloides (Koshi-abura / こしあぶら) = may

be not in the west and its bitter taste may be too strong for other than to Japanese ). —– Yet, I noticed, this

Japanese tradition may have some displeasure to the western people which might be originated

from the difference of the natural environment in Japan, and their attitude toward the plants.

= In comparison to the England where only 20% of the land is mountainous,  Japan got their 80% is the mountain

= hence the area where those plants grow is huge and those plants are everywhere = human activities wouldn’t

affect so much (anyhow people wouldn’t go to the same area which got too much competition) and

the plant would recover by making side shoot.

[]

—– It may sound too funny though, only a week or two ago I discovered that I can use Google and Wikipedia

in Japanese. 😀

Because of my knowledges of the plants are all in Japanese, I didn’t necessary wrote the name of the plant in English

or in Latin before. —– But when I Googled and saw Wikipedia in Japanese, then found the English name, I noticed,

some of the plant which Japanese eat, are the garden plants in the west.

Like Foster, they are quite common in the gardens here, and in Japanese mountain they are everywhere.

= they are easy to distinguish and easy to cook such as to put into Miso soup though, the western people may not

feel comfortable to eat them as they make pretty flowers.

The Japanese “Udo” Aralia Cordata is now widely sold in England with a fancy name of “Aralia Cordata Sun King”

hence people never considered to eat as “Udo” like Japanese does.

There is a very firm idiosyncrasy

= plants in the garden is only for visual pleasure never for eating !

And they may not want to be seen as an hungry people. 😀

Kitchen garden might be only for a show-off of their rich folly and for a talking piece.

—– For a Japanese, nature is not just for looking at. They eat a lot from the nature as well

= literally living together.

Poppy = Impressionist’s photography / W-Pinhole Photo

As it is in the season, I’m seeing number of interesting photos of the Poppy in the Net.

One Photo-blogger Lemony showed her Poppy photo (link here) taken while intentionally

shaking the camera and created blurred image which I dubbed “Impressionist’s Photography”

and I promised her I’ll show my “Impressionist’s Photo” —– hence, here they are.

Isn’t this Impressionist, is this ?    Ha ha ha,    🙂

Those photos were taken by the Pinhole camera (Canon 5D Mk2)  but in this time it was by

two Pinholes of which the panel was fitted on front of the extension ring, therefore the

effective focal length was 84 mm.

With Two Pinholes, it produces off-positioned two images = similar to double exposure image,

or there used be a Double Image filter which used shallow prism = but such image can be made

by Photoshop much easily now. —– Still, I like those images, if the paintings of Impressionists

are still the painting, a photo of pinhole is still the photograph. (Why not ? )   😀

(What so ever, the best of all, two pinholes can make twice as many flowers instant.  😀  )

This photo was taken from the same position, but the Light Balance was set to Tungsten Light,

hence the color balance has shifted to blue. — (then,  contrast was increased and cropped)

= the image became even more like an Impressionist’s or an abstract painting.

This is an ordinary straight shot = as for a reference image. (Lens was Canon 70-200 F2.8 = set to

about 85 mm, and set to F4. —– ( This image looks like a Japanese Yamato-e Paintings.)

With the light balance set to Tungsten Light, it made the pale colored image more like a

Chinese panel painting.

Then, the same Poppies’ were taken by W-Pinhole. (not only the effect of the Pinhole, but

the wind shaken the flowers and made the image even more impressionistic  😀  )

(Under the wind, no flower stand still for 10 seconds, especially delicate Poppies )

[]

It seemed like the same situation, when people was bored by the too clean digital sound, they

started to go back Veiner or even Valve sound = when too clear sharp photo became too

ubiquitous, and easy to achieve, some went back to  B/W  Film Photography, some are even

trying to make their own print paper applying photo sensitive emulsion onto own material to

create textured fuzzy image (strangely, often fuzzy image seemed to have more connotations)

= there could be hundreds of the way to do photography.   (—– not only Pinhole   😀  )

This is the 84 mm W-Pinhole “lens” (?  😀 ) I’ve used.   Panel was a thin aluminum of a beer can

mounted on front of an extension ring.    Photo right is, with its “lens”  hood ! —– without lens,

it’s still need to have a Hood = you believe or not.  (Normally, a lens hood is to prevent a direct

sun hitting the lens = eliminates a ghost and halo.   Yet,  Pinhole without lens still needs to reduce

the light from the sky etc, which creates halo by scattering inside with diffraction. = Most of 

Pinhole Photographer doesn’t know this, as they think,  even the unnecessary halo is still the

character of the Pinhole photo  🙂  )  = Here,  seeing is believing.

Photo left is without Hood and the right, with hood = the difference is clear.    🙂

Film Premier Show in Secret

A big film was shown as its Premier.   And it was performed in its iconic set-up.

So that, it is hard to say is this a film event or an art event ?  —- what so ever  it’s

an event to have very interesting, fun-full evening.  😀

————————————– (photo = simulation of the space craft landing)

As I’ve been asked to give technical advices and to assist with my electronical expertise,

and to show my art piece — strangely,  I was restricted by their Confidentiality Clause, hence

I can’t disclose the name of the film. (They says, Don’t tell to others until the event finished ! )

—– still you can get the ticket  from their web-site which I can’t  give its name neither  😀

Secrecy seems to be their secret of the success,  hence thousands of the guests are keep coming.

(Contradictorily,  they hand-out a printed program with excerpt from the Guardian News paper)

Now, month long show was ended, we are free to disclose the details and I can put more photos.

The Film was [Prometheuse] and the show was organised by [Secret Cinema] (link here).

The event was held in a secret location, still it is a conspicuous most event full event

= suddenly somebody got mad and the securities had to strain him ( according to the story

of the film = lots of happening etc. etc = to make a fun and unexpected experiences)  🙂

Go into a certain area, participants were given protective garment and taken to

the dark under world.  (This photo is for a lady who wanted to have it to copy and save  🙂 )

Then, discover such as an impressive installation of projected water vortex (video image was

created by  Doug Foster ), reflected on the water in a dark space, accompanied by the good sound

effects.  = Atmosphere is mesmerizing !   It was designed by my friend Francesco Pastori.  

(I’ve worked with Francesco in many projects together).

In the dark, luminous lines glow,  and with a head-light of a guide, you may find the confusing

multiple reflections. (Created by  Das Patterson)

Luminous tape in the dark was photographed, while camera was hand-held 5 second !

Or, go through spooky passages to discover yet more strange installations, inspired by the

concept of the film.  (Some are gone a bit too far from the story though, it’s not a problem  😉 )

Sound interactive LED lighting.

Or, Hydroponic agriculture system supposed provide the vegetables on the long voyage   😉

( Around here, Science lab’, Museum etc was produced and directed by Luke Harcourt )

And this is my Life Bottle, —– the Tissue culture to grow the life.  😀

(It is in the Science Lab —– don’t miss it, if you visit there  😀 )

When you are tired, the bay for an Hyper-Sleep was provided though, I haven’t tested whether

the sleep was automatically induced or not.  (or you can play Basket Ball instead )  🙂

To have a drink or two, many Bar or Restaurants are there.

A restaurant with live Piano (sound nice), or hundreds of real Lily flowers with its real smell  😉

Some Restaurants looks rather posh —– the guests may need to buy VIP tickets — ?

( As a poor Zennist, I have no idea how much the cost of VIP tickets are.  😀  )

Suddenly all the participants were assembled in a big room and the instruction was given.

The characters from the film were waking around etc. etc —– .  🙂

Then the clouds were lead to the another space to see the film in 3D !

( Though, as I said above, I can’t give the details of the  film = it was an impressive film   😀 )

( Now you know the Film though, it too late to go) 😉

It is amazing to see the good grown-ups having such unusual funs and enjoy the good time !

( To join them, you have to find more Info’ by yourself —- Guardian may have wrote about )

The event continues month long  = it’s mean I have to go-up there, time to time to change

the water in my bottle  😀 —– (By the way, I’m not payed ) = It was just for a FUN !

To have my own fun, I didn’t need to pay for them neither ! = it’s a secret to have a  smooth

uncomplicated life = Just respond to the situation without too much thinking or greed = this

is the way of the Zen Life, in its full of action.  🙂

When you live, there is no need to have an excuse or any justification = Just live as you have

happened to be in this world.   You didn’t chose. Still, you need to follow ! — What happened

was the situation given = You only got to do what you can do in your best = Hence no regret.  🙂

Cheers.

PS :  To the artists who’s work has been photographed here, can copy and use it free, if the one wish to do so.

MEMS Microphne

I guess, the most of the readers may not understand what

this title means.  —– yet most of the people are using it

only without knowing = it is a microphone inside of

Mob-phone or Smart-phone.

= If you ever disassemble or happened to see inside of a broken

phone might have noticed a component which got a hole, right

behind of a hole on the phone’s outer shell. ——————————————- (Photo  Knowle’s MEMS Microphone )

—– In the past 10 years, the microphone has changed their round shape into square and the

principle how it works has completely changed.

[]

When I was in my junior school, I was a member of the Radio Club and we were in charge with the preparation

for a morning assembly or any event which use the PA system, and the control of the PA system as well.

(and often to repair them as long as we, together with the supervising teacher can manage )

Among the old disused equipment, I have seen Carbon Microphone and many

Crystal Microphones.  But the main Microphone on that time was the Dynamic Microphone.  

Then the teacher showed us latest procurement of Ribbon Microphone which can produce

much better sound quality.

[]

The granules of Carbon changes its conductivity under the pressure = hence put them

under a vibrating membrane can work as a microphone which needs no amplification hence

it is a cheapest kind in an audio system. ( Connect a carbon mic directory to a battery and a

magnetic head-phone in series and make a loop = it makes an audio communication system !

—– though, sound quality is not good at all, yet there wasn’t

anything else but Carbon-Mic even in a recording industry then.

—– The carbon granules absorb moisture, and a singer blows her breath to the mic, a recorded sound

deteriorates with its use !   So that, the top singer wanted to have a morning session, not in the afternoon 😀

(It’s from “History of Recording” kind of a book I read long time ago )

Carbon-Mic has been used in the Telephone system well into 60^th and I bought some of them in a second-hand

market (to see the inside and experiment with them 😀 )

[]

If you are a musician or dealing with sound systems must be familiar with Dynamic Microphone.

They are technically the same as an ordinary Speaker. = a coil was attached to a vibrating membrane or

speaker corn. —– the coil is placed between the magnet, so that, if it moves, with Electro-magnetic effect

= the changing electric signal will be created = this is a microphone.

But when electric signal was applied to the coil, it will be either attracted or repelled from the magnet hence

moves the corn according to the signal = this is a speaker.

—– So that, in my secondary school, once I connected the cables which goes to a speaker of a room of which

the teachers meeting was held, to a Microphone input and able to over-heard all the conversation.

( I didn’t disclose what I’ve heard and this is the first time me to revile the story 😀 )

(There is the matters in Impedance matching etc, but it worked and most of the case it works 😀 )

[]

In the old days, there was a Condenser Microphone in a Mob-phone. —– in any small devices, the Mic was

almost all ways a Condenser-Mic (commonly called Electoret Mic)  = Condenser Microphone was made of

a metal coated thin plastic film and the insulated metal base.   Two conductive plates facing each other having

an electric charge between them hence it was called Condenser. —– This electric charge changes if the

membrane vibrates with a sound, and this changing charge was amplified and used as a sound signal.

They are simple and small hence cheap therefore they were used everywhere despite of the sound quality is

not necessary good.

But since 2002 it was replaced by the MEMS Microphone made by Knowls (Google please)

( I saw a news, that their sale of Microphone reached to the 300 millions, since 2002. = Oh, Gosh ! )

= microscopic whisker suspended above base conductor, vibrates with sound wave, and this vibration was

converted into the electronic signal.  The cavity inside of Microphone should be designed to resonates with

the sound hence it works as a microphone.  If its whisker was made sensitive to magnetism, MEMS act as

a Compass, or when it detects the gravity it tells whether the device is upright or horizontal, like iPad does.

[]

Once the basic technology was established, MEMS devices infiltrated everywhere in the past 10 years or so.

Microscopic moving part was made by electro-etching (chemically dissolve and removes the material and

make a metal parts in a wanted shape ) or even carved by a Laser beam.

And the minute movement of this part (whisker) hence its change of the capacitive charge was detected and

converted into an electronic signal.

—– Can you imagine, in a so-called Motion Sensor such as in a Wii controller, microscopic whisker moves

with the movements and its movement was converted into an electronic signal to control the game.

Microns long whisker which was made of,  may be few thousands of atoms lined up, would be bent with its

flexibility, hence the electronic charge may change accordingly, and this change would be amplified,

—– but amplified to how many million times without noise. —– as they are commonly used everywhere

now, it mast be just reliable or even better than old technology though, still it is incredible to me.

[]

So, having an old rusted brain, I rather indulge an old memory, when I saw a small light bulb

connected straight to a Telephone’s Carbon-Microphone and battery, changed its brightness

when I pressed the center of the Microphone.  = It was a delightful amazing moment for a child !

How sweet and peaceful, in our old days were 😀 😀

DIY or Expect Others to Do it for You ?

Somebody asked me “ How I could cut a plastic jar (in Lens Cap post = link here)

so clean and precise”. —– well, there was a bit of preparation to do it which you

can see in the photo I’ve took on the time.

When you cut or chisel the material, there is a rule [Firmly fix either the tool or the material].

Even to peel a skin of an apple by a knife, there is a knack,

“It got firmly hold the knife and only rotates the Apple, not other-way round”.

Therefore, to cut the plastic jar, a sharp blade was fixed on the flat board by a G-clamp

(hight was adjusted by something such as aluminum bar etc under the blade which got

suitable thickness) and plastic jar was rotated on the flat base while pressing against

the blade.  (while rotates it, never wobble and rotates many times

= cut it gradually deeper)

This principle is always the same = cut a pipe or bar using a hacksaw, fix the material or object

on a vice clamp.   When drilling a hole = only the drill bit moves but not the material.

On a Lathe Machine or Wood-turning Lathe, only the material rotates and the cutting-bite which

was fixed to the machine, moves slowly while having the position precisely controlled.

[]

In a hind sight, I was lucky to grown-up in Japan where everything had been burnt

down and had nothing else of the abandoned field with wild flowers and insects.

Having no ready-made toys, we had to improvise or make our own toys.  And in the

magazines, there was a lots of article of “How to Make Something by Ourself.”

—– Grown-up was literally meant to know How to Do = not just

to know the names and words.

[]

Do It Yourself mean, to learn the material, and to know and having the control

of all the process, and to take a responsibility for the result = no one else there to

take a blame but oneself.

—– in this aspect, I really pities the kids and the grown-up version of those kids = young peoples

of today = while growing up with a toy bought by somebody-else’s (parent’s) money, without

knowing how it’s works, let alone how it was made, and only know to buy another one, or blame

somebody-else, such as the manufacturer,  when it was broken.  No idea of how to repair it.

[]

This utterly irresponsible, only expecting to others to do, mentality is the

fundamental problem of the whole society today.

Without knowing whole system, but only know to press a button (like a game-machine), and handling

even a financial operation, just for a short-eye-sighted gain, only on his narrow scope of speculation

= then end-up to pile-up uncontrollable amount of debts = yet still expecting somebody-else

(IMF etc) to bail-out their problem. —– (But, where the money of IMF come from ?)

A system having no feed-back and built-in self regulating mechanism,

it can not be called a system.

[]

Still amazing things are, the people are flocking to buy share of FACEBOOK,

while speculating it would grow and creates big profit.  But the reason why F’ is

floating their share in this moment is, that they realized no more growth in

a sale of AD business = This is the last opportunity they can fool the people.

GM has already stopped to advertise in F’ since it didn’t sell their car. 

And as majority of the F’ user were shifted to see F’ in their Smart-phone,

= who want to see an obstructive AD in their small screen ?

This is the typical sample of “Greed blind the people”  😀

Where the money to fill their Greed come from ? = are they still expecting

somebody else to create the money and give to them ?  Because of it is nothing

certain, F’ is doing it somebody else’s money. ( Sell the Share to public) !  😀

Heaven’s Thunder to New French President Holland

When I heard the story how New French President Holland was treated with a heavy

rain and the thunders, I burst into laughing with my own memory.

When I was in Japan, I had ill-fated marriage —– I’ve married when I was 22 years, still in my Uni’.

In fact, everything had just carried out but not necessary in my control. My parent’s prediction was,

“ The inevitable separation is there, it’s mean, the best time for it is, now ” though, it was too late.

= hence, marriage process went on as it was expected in the traditional custom in a formalized way.

[]

A sort of resistance to prevent the notorieties and the old members of wife’s family (bit too traditional,

big clan’s) coming to the wedding, I planed its party in a mountain top Hut, which was a sister Hut of

the mountain shelter where I was a voluntary keeper since I was 15 (= first year in a High School).

Wedding ceremony was conducted in a big Shinto Shrine, Suwa-taisha (諏訪大社), and we drove up

mountain hi-way with 10 of the cars. Then we started to climb to the top, on foot for 15 min’ walk.

—– It was a beautiful blue sky though, utterly out of blue, while we were in the middle of climb,

suddenly big cloud appeared sky above, and started a heavy torrential rain.

I run up to the Hut and grubbed all umbrellas and back to the guests of party though, it was such a

heavy shower, everybody,  include my Mother,  the Best-man (my Professor in Sociology), and

the staffs from Makino Harbarium, members of the Alpine Club and old mates, all got soaked down

to their undies.  When everybody reached to the Hut (and everybody changed to their pyjama) the

rain stopped and back to the blue sky. How beautiful.

[]The word of my Mother was “ Oh dear, this is what the Heaven is telling you”.

—– After 7 years, we divorced and I left Japan.   And I’m still single. (how peaceful 😀 )

—– It could be just a sheer coincidence, yet still, there could be something.

When our Emperor Hirohito departed, the day of his funeral was in the sleet. Even though a day

before, a day after were both fine day. —– I thought “ Oh, even the Heaven cries for him”.

[]

—– You may say “ It’s utterly nuts” and I’ve been saying “ There is no mumbo-jumbo”

though, there are too many strange phenomena in my life, such as  [8150 story] (link here) or my

Cat’s stories to name but few. — So, I’m well qualified to make a joke “ Oh, dear, new French

President Holland is going to open the hell” 😀

Good luck for him (to challenge hopelessly impossible task. Apart from attracting the voters

with sweet words while giving a false expectation, actually achieve the growth with no cash left in

the pocket, it’s a hell lots of good luck from the Heaven needed).
