Angry mountain

2011-07-12T08:21:00.000+01:00

Storm in the mountain,
as the weather change, the hard storm pass from the Hochstuhl mountain 2.237m,
true the wally. I was try to catchh some tunder strike, no good luck this time.
At least some nice shots and colors come true!

Moth lowrider again & new hydrofoils mold

2011-06-24T22:26:00.002+01:00

Mahalo,

as happened last year twice, to be on Moth boat "lowrider", not "Love rider"
2010 broken hydrofoil

I did it again. Broken main hydrofoil in T connection. Now is this set up dead,
no chance to make the third repair. I also will not because the new hydrofoils are
knocking on the door!

The T connection looks like the explode from inside!

The MDF molds before finish!

The flying boat will be in short equipped with new hydrofoils. The vertical rudders
I am looking to keep the existing ones, and build in future new setup!

Re Design of the sensor Faucet

2011-05-19T12:09:00.002+01:00

For the VS company we are in A good mix of Creativity studio, make a step forward with design in the process of "face lift" for the sensor Faucet . On the first step we re-engineering the existing Faucet to parametrically values in Alibre design CAD system. With this we can on time checking all the elements in Faucet and tolerance on elements. When designing, a new input was taken into account all possibilities of new manufacturing technologies, including automation. The product has got a new look with approach of industrial designer, who was responsible for visual shape/look and he worked closely in the design process. For dimensional and functional verification, we make in the company Chemets, Kranj, prototype of the Faucet with the laser sintering (SLS technology). Based on this model were established silicone molds for casting with polyurethanes resin. Model of the Faucet was made under the process of vacuum casting of materials with similar technical characteristics as the later finished products. Technology and process ensures maximum flexibility of manufacture to the requirements of product in this case, especially for the different configuration of accessories depending on the specific customer product. This covers a very important niche in the field of sensor taps. Using CAD design and manufacture a prototype according to the methods of 3D technologies, we significantly reduce development time product, in particular, its accuracy and flexibility for development and design.

Moth hydrofoil 2011

2011-05-06T12:13:00.003+01:00

Mahalo,
again long time from my last writing on the Blog, standard reason is too busy on different projects running in my life and work. But thing going on step by step, fist of all Moth will get new hydrofoil, the original was last summer twice broken, it is still sailable but bad performance. I start to design new one over the winter and it was on the CNC machine for the first cut.

I will write more regarding design construction in next posts,
here and now just some shots of making off!

Eda 5 replica goggles

2011-03-26T10:58:00.001Z

And again, years ago I was made for mr.Albin Novak the author of replica plane EDA5 the male pilot model, that was somewhere in 90tis. For new history exhibition of planes he made new model in 1/2 scale! He got new pilot but without pilot goggles! I was kindly invited to make new ones. As in this stage the goggles was constructed in 3D CAD software Moi!

Eda5 1/2 scale made by mr.Albin Novak

Retro goggles constructed in 3D Moi / http://moi3d.com/

The state of the art technology chosen was the SLS 3D printing, weary good result on the product with measurements of 70x28mm!

The cool retro goggles was finished painted and assembled with gummy strap around Eda head!

Eda is now ready to take off, for exhibition, good fly Edvard!

Autumn Glory

2010-12-22T21:18:00.001Z

Once it was a wish and the wish become reality!
The goal was to have the Autumn Glory
violin ready to play before Christmas!

Two days ago the new violin give the play, it is wonderful feeling after all
the work to hear instrument at work! Again prof. Tomaz Pinter
help me with the experience of master. Violin have, before the sound post was positioning,
really big troubles with "E" string oscillation. So strange and ugly tone, unbelievable!
After the sound post was insert the oscillation disappear in 90%,
it is still there at the hi tones but looking what it was is perfect!

Here it is, the Autumn Glory of itself.
The redwood hybrid plank mixed with carbon fiber and honeycomb sandwich,
the carbon wall and the "standard" scroll! Maple neck and ebony fingerboard!

The sound check was done at hook no preparation, really from the heart, enjoy!

Christmas nativity

2010-12-13T12:26:00.002Z

As every year, like some tradition I am making Christmas figures.
For his year a some past designs was used and reproduced.
Looking in direction to find optimal relation of hand craft and design,
with the traditional nativity scene turning a work in modern art!
The small ones are made from acrylic glass, laser cut and
base of palisander woo! Height app. 15cm.

Bigger one represent the wood carving base&background with acrylic figures!
The American walnut, brown red structure was rough milled on CNC first and
for the finish, as must to be carved with knifes! So pleasure work
with the smell of wood!

Enjoy the rest of the days left before Christmas!

Violin second step

2010-12-06T12:43:00.003Z

Time is running me away like a hell,
the second violin is on the working bench!
In process of design I have now four violins.
It will follow the fist one step by step. Soon the second
one will give the sound, then the decision on technical
futures will be made for the next steps.

"Autumn glory"
Light reed wood, ebony fingerboard, carbon scroll, some nice
details on the wall! Some pictures of formation are bellow!

"Celtic beauty"
In full carbon look, with gold Celtic graphic on the planks and bottom/upper nut
from brass! Pure extraordinary look as Celtic beauty desire!

"Dark vibrations"
Reed wood, dark fell, Wood look, fingerboard carbon on palisander wood,
tail piece palisander , maybe the peg also, chinrest palisander.

"Yellow madness" Yellow wood, with carbon frame and ornament purfling!

So this are the plans, lets see whats come out of this!

And again here we have some nice material patterns!

Enjoy life!

Violin passion part VI & sound check

2010-11-12T09:05:00.004Z

Dreams are all about we are looking for,
the violin come to the point when professional musicians
like my good friend prof. Tomaz Pinter take
the instrument in his hands. This is the moment I was
waiting for! You too? Not scary, just celebration of the sound
and the shape. The concept works well, only some
people see the violin and they are happy, surprised,
cool about, me too!
Go forward dr.Lojz go! Yes I did, there is no way back!

Take a look and listen the sound, some fine tuning will
be done in future and new violin is already in my head!

And not to forget for the HiTeak violin from 1995 was played also:

This is one step more in my life full of passions and Violin is for sure one of them.

Thanks for all who support me on my way, this ones who are on direct contact with me

and the some of you who stay like a shadow in my life! Big thanks!

Violin passion part V

2010-11-11T10:37:00.003Z

So far so good,
The master piece assembled,
first photo shooting completed!
Violin survive!
Me too!

Here just some overview shots to get better feel all about!

Enjoy life,

violin will be played today,

so more info will follow!

When I get from violin masters the first opinions, will be posted here!

Violin passion part IV

2010-11-09T07:41:00.003Z

Here we go, no matter if the weather is cold, rainy, gray, pushing down, who care!
Sure we get some new snow in the mountains and when the sun show up will be perfect.
I have my own light to keep me up! The violin make new steps forward and make me lucky.
The final assembly of the body was successful. Well I must to made all the clams new, but this help really to get the instrument into right shape. On the photo bellow we clearly see the parts before assembly. Closer look on the parts show us the construction and innovations on the master piece. The rib of violin is completed with sandwich of wood and carbon fiber /45deg CFK and wood vertical/. The belly and the back /plank ;-)/ are of full spruce wood and the neck is maple. The fingerboard, what else then ebony, so great material to work with. The main core innovation is the carbon tube connecting the neck and the button at the end of instrument. The tube will translate all the forces of the strings to release the body to be free for vibrations.
Well done on this point, let's free the ideas to the life and make some music out of it!

What's come next, sure final tuning, the strings, bridge, peg's and start to play on!

dr.

Violin passion part III

2010-11-03T08:42:00.006Z

Work on the master piece going successful in direction "mission complete"!
The famous "F" holes was cut out, the shape of the holes was taken from my fist violin, the outline and the position was slightly adapted to the new design. At this point no supersonic technology can help, only good hand, sharp eye and patience! Done nicely, enjoining the shape and precisions!

The carbon fiber on the bottom destroy for each hole one hand saw, no problem if the result is positive! Good to have proper Fret metal saws!

Violin scroll, one of the famous part of the violin. Each lutenist give to this part his own touch and design. The violins can be recognize bay the scrolls as well. On modern concept design of violin my contribution to this is design and technology to make and to have the carbon fiber scroll. Looks from done product completely easy, but is not. First step is to decide and construct the spiral of the scroll. A lot of good help it is possible to find in this book of Sergei Muratov, he was calculate the violin completely as many others! In any case perfect work from him! Many of different ways I was try to complete this shape technological wise. From all at the end I still need my hands, eye, good feeling to bring this shape as it is! The task is successful done and the result is awesome. The black fiber run from pegbox into the infinite line, surface of the scroll! Perfect! At the end late at night for the first time the violin is temporary together with all the parts, just for better visualization! Lets go to complete this instrument, I am waiting for!

dr.Lojz

Violin passion part II

2010-10-31T18:43:00.004Z

As the word was given, the pictures says more then words! Step by step illustration of the making of! Almost all the parts are done, even the carbon fiber scroll, which was real challenge. More of CFK scroll in my next posts. Here we have some steps of couture, milling of belly and bottom, cutting of the couture!

The graphic was applying o the top of the belly in vacuum process as well the bottom. The neck was construed in Alibre.com and milled out from the wood block. At the end the finished plank have less then 75g. What this mean will be clear when the violin will be played!

On the plan is final assembly and the mystic of the carbon fiber scroll! Follow this space for more information's!

Thx dr.

Violin as a music instrument and excellent wood hand work piece, not to mention as design part, it is a wish to be touch for any designer. It touch me as well! First time on the university, late 80'! I visit the luthier, tell him my wish to make violin, He say, yes, yes my young friend, go ahead and come back to me, time to time. Well I was visit him twice precisely and forget for violin for 10y. Not completely forget, it stays in my mind somehow!
In mid of 90' I was back made for my good friend the weeding present! Here it is the Hi-Teac violin:

Did I am making good designs only for a weeding presents, I hope not, two of them for sure, the Eric Tye and Nejc violin. In late 90' the second one was made the same shape, technology and design. The second one is in my hands, it was made them for design exhibition only!

After 10 years I am back with violins, this time on my workbench, better to say on comp and CNC and workshop is the new one.
Hybrid violin, still without name but the fist info is here!

From this CAD drawings, not much to see, but from technology and design will be real masterpiece! I will tray to fill up time to time as the steps and results of the work!
For the better visualization some renders of violin!

As it is possible to see the shape remain "classical"! And this is all. The rib is done from 45deg orientated Carbon fiber vacuumed with weenier! The belly was taken on CNC out of full wood, then the carbon fiber layer was under special technology laminated on inside of "plank". The top part get the grafic on, violin will be finished in week or so and in this time I will post some steps of technology! Watch this space! Thanks to www.Alibre.com and Keyshot render software on help to have this violin on realization!

Late October

2010-10-30T20:17:00.000+01:00

Well summer is over, defiantly, we get fresh new snow in the mountains! Moth was find a place under the roof in workshop, will be well stored over the winter. So for next five months no sailing on fresh water. The remains are still alive, like this one from neighborhood lake Osiacher see, where we was with local sailing club, enjoing the wind:

It is good to see "old" Axeman still alive after broken foil, scratched tramp and and so on!
For this summer I was broke the main foil twice! It was reparid twice as well and it is now
in bad shape, well still working, but not 100%. The main flap must to be adjusted to get more
lift at speeds under 10knots. For the moment no big plans for moth activities over the winter, for sure some designs visions will be proceed!

Carbon fibre Tie

2010-06-25T11:09:00.001+01:00

What's this?
It is long story behind, almost 15 yeas when I made design
and weary first CFK Tie! This was pure art design with
strong connection of hi tech technology.
And what's happened now, my friend Eric Raymond
made end decision and he will get married with Irena on Saturday!

He is the man behind Solar Flight SUNSEEKER,
he find the N Slovenia and the Alps flying area
as his new home. Well you can not be alone so Irena
join his way to go! At the end of this part of life
they have official weeding at Saturday 26.june 2010!

Eric at NASA meeting /wearing blue Tie ;-) /

What a weding present I can make for a man plying with
top art of technology?? After brain storm and couple
conclusions the end decision was done, Eric will get
for his wedding Carbon Tie! Well done!

The Tie is made from real carbon fiber in vacuum technology
with insert of mahogany! the top part have waves shoving
and simulating the flapping of the tie! True the waves
is going hi polished brass stick ended with a sphere.
At the other end the mahogany elliptic oval connected
the wearing neck brass circle!

Here it is the carbon fiber Tie!

At the end I choose simply gift wrap from the florist shop and
Tamala help me over the net to choose the right flower for this set up!
Orange-Yellow Rose, supper one!

It looks like this when I give the present to Eric......

He was in workshoop when I jump in, with surprise, give him a Tie
and he stay speechless! Good done!
I whish to Eric all the best on his futre steps in his life, I am glad to
support him on some of his fliping mind projects!
Go, Eric and Irena, go!

CNC fins

2010-06-22T07:17:00.001+01:00

Mahalo,
On the work to get out of the StealthRace board as much
as possible out, on one point the decision was to make
new fins! As I say the board is good, but it is too difficult
to ride, in comparison to other boards.
I am working on force pattern and from there the
conclusion is to have the middle fin smaller and the
"wing" fins will get new higher position.
Using Alibre CAD the fin was constructed and on
the end milled on machine.

Again the nice CNC patterns, which every time fascinating me. This is

so good to see how from zero coming up the product out from machine.

The modifications on the StelthRace board go step by step, dutue lack
of time from my design studio working day it is simply too much to do.

Update week 23

2010-06-13T22:30:00.004+01:00

Mahalo,
it was fully week of sports, surprises, tests, crashes
and historic feels. Lets go step by step whats happened.

First of all I get chance to go on water with modification
foils on my Moth sailboat. See the blog here
On local Bled lake the conditions was nothing special,
but enough to get the Moth on the foils. Conclusion
is simply, the modification works well, before I was
not able to get up in low wind or with such a small
speed. Everything OK.
Later on week the forecast was better for Bohinj lake,
so I was there, looking for a nice session. But, mr. Murphy
was on work, First I was cut the trampoline, where is attach
to the boat, OK bad luck I say and go for new track.
But on some crash from foiling I was swim around
boat, I see the main foil broken, o holy s*! Only chance was
to sail direct to start point and the session was ended!

Here we have the broken main foil

Not really happy!

Angeled for couple degrees, with destroyed inside structure.
At the moment I am taking decision to make repair or go
for new design, h'mmmm????
And broken tramp, well or I am too hawy or the tramp mesh was old!

On Friday I have chance to go on Lago di Croche "I" for the second
test on Stelth race board. The results will be summarized and publish
here in short. The board get some modifications on and for first info
the max speed at the wind of max 12-14knot was 26knot. Not bad!

Follow this space for future info!

Today we have in town the meeting of Old-Bikes, I mean really old.
Ota my daughter ask me to go together and we go. I was ride the bike
from my grand father the German Wulcan from 1930 which I owned.
Ota was on the bike from 1960. Great party to meet so many bikers
with history behind!

Here we go Ota and dr.Lojz

I was able to have chance for a "test run" on oldest replica bike this day!
Only one to say crazy feeling to be part of history!

Wood wheels, steel rings and wooden seat, direct transmission and
HARD servo steering, bombastic!

Stelth_race_KB_update

2010-06-03T14:31:00.002+01:00

Mahalo

As this Blog was created, with Stealth_race_KB was achieved the

goal given. The concept kite race board triggered a lot of dust on

kite forums all around globe. At the

http://www.kiteforum.com/viewtopic.php?f=1&t=2364658&start=0

thy made more tthen 1100 reads and counting in 3 days!

Thanks for all supporters on this idea of the board. I know

I am on right way, there is no compromise!

The board is at the moment on final tuning of the straps and fins

positions, looking forward to be for the coming weekend

ready on the water. So far so good!

Looks like if the interest for the board will grow up with

such a tendency, then some number of the boards will

be produced out of negative molds, the question is just to

set up enough orders to get good calc out!

Follow this space for more information's coming on!

2010-05-29T17:37:00.005+01:00

Mahalo,
Lucky with the finished board the Poseidon cooperate too,
thanks to him, I was able to made weary first
run on the water. With the support of my friend Jani, the
destination was clear, go to coast!
I don't have any idea what will happened, the idea and
the galactic flow was too big over the development
time. One was clear, once we are 100% focused to the
final point the result come on suddenly.
In Grado North Italy the S wind was 8-12knots and it
was promising for fist attempt.

The Stealth kite race work as was predicted without any troubles on
the edge/classic kite style/ Fins are holding like a hell, but wait,
when you press the board flat on the water, "stealth" effect come on.
The board accelerate as a sports car, there is no comparison to
the "normal kite" board. I am talking from my 12 years guru status
in the sport, from early beginigs. The board was justified expectations
and the final trim on the straps and fins will be done in the future.
I hope I will in short get the Gps to be more precise on the
physical data, for me this is the most important point, just in front of
personal opinion and 3D design!

In any case we was enjoy nice sunny day, good wind for such a riding
style and perfect day.
See you on the water!

Stelth_race_KB_finished

2010-05-28T15:32:00.001+01:00

Mahalo,
it is so far, the board is finished. At the end the right
description for the board could to be the concept kite race
board. The time will show on the right direction of the concept.
Some qiuck facts of the board, 1750mm long 500mm wide,
board alone on the scale 4,9kg, but unbreakable! From my
know-how some of weight can be taken off from the
original layout. It is not exempt chance to go in direction
of negative molds, lets see what the time will show on.

Here the are, her majesty the Stelth race in life. For all those
who not believe and comp renderings are not enough.

The board here is without pads, will be added later on request and ready for
some serious tests on the water.
See you in 10knots with full speed, upwind! Can't wait!

Infusion composite

2010-05-28T14:51:00.006+01:00

Mahalo,
lets go step by step on technological procedure on the new race board
designed on my side. True weary complex construction of outside
fins on this board the end decision was to use the infusion technology
to get the ruff plate of GFK. The simply mold of Styrofoam was made
and in next steps the 12lyers of glass-fiber was lay down on the
positive mold surface. Vacuum bag all around with inlay tube for
epoxy, on the other side the air out. Less then 1h the resin was come
true all the laminates. Slow flow of the resin true the 7mm of glass fibre.

Front view of the fins block material

And once again the flow of the resin true the GFK, like a miracle!
The middle fin material was prepared on the same technology,
only the "mold" was plain table!

It was quite hard work afterward to get the fins in right shape,
but they are looks great when are mounted on the board.

2010-05-05T14:52:00.003+01:00

Mahalo,

the new race board go step by step to the direction of masterpiece.

With the help of Aeroprodukt company we successful make fist

step of lamination. The board get the shape of itself.

I was looking to get better contrast on the veneer wood straps,

but the middle pieces come almost black out, that's life,

design vision and technology.

The reinforcement for the side fins and the inserts:

The veneer sheet ready to go, middle Macassar Ebony straps and outside the Koto veneer.

Here it is, the master piece done at the fist stage!

I am looking forward to have the board finished ASAP, the season is almost starting.

The middle fin was injected with infusion technology today successful and will

be fun in next days to infuse the side fins with there "strange" shape!

Lets go to work!

Kite Race Board

2010-04-18T20:06:00.014+01:00

Mahalo, well long time from the last post I write, there was a lot going on!
Not I am lazy to write, but just no time to seat down and type on.

In last 3 years there is a lot going on on the kiterace community. I was always more on this side of kiting, mean low wind and pure technical sailing. Going fist on the water, or be the last one on the water is special feeling! I like it, you can believe me;-) In the last decade the kite community was not really focused into low wind kiting and this is changing. The group from SF sailing club was push from year to year the whole series of kite race, this was move the group of kiters out of hardcore freestyle to the course race. I like it! For me interesting are the boards and technique of riding. If I am looking back and compare today boards for race they look like the board I made in 2000!

Here they are the race boards of today! Huge planks with even bigger fins, interesting enough to jump into and prepare my own design. One weary important point on the low wind and also on course kiting is perfect planing of the board and good hold of the fins. As everybody wish no sniping please. The board is "classical" shaped, the widths point is moved back from the middle, quite square tail and "big nose. Almost 1/2 of the rocker line must to be flat. This make the board good planing and speed. The rails are on front round and completely sharp /90deg/ from middle to tail! I decide to go with the top surface in 3D to get more ridged construction with less weight. On the tail I need flat zone to mount the fins on! The design of the board looks like this: Looks relay unofficial in CFK look with 3D top and veneer strap in the middle, even more difficult to understand are the side fins. But wait they are there for a reason. The middle fin will keep the position lite it is "state of the art" on the boards, the front fins are moved out of the board to be in clear waterfowl to get as much as possible track and force out of it. The end decision was done after all the analysis and comparison measurements. The fins shape are up to date the best of Aero and hydrodynamical calculations and yes they looks like fish fins, surprised, me not!
Bottom flat part of the board! And for the end the whole shape in one top view! I was not mention before, the whole board and everything else is drawn into CAD parametrically, used the latest SW technology and calculations. The core of the board was milled out of foam core with CNC machine, on this point is no comparison any more with hand work and precision! The decision was right! The board will be laminated in the rocker table in next days, so keep this space for future news! Then on the water to push this stick to the limit! Looking forward and I will be back!

The first "studio" photos of the RedBox

2010-03-27T21:29:00.006Z

Mahalo, somehow timing is not on my best side, specially here at the Blog, from the work and life works well! For a step back on FireBox, we have done first two of them, FINISHED and sends to German company, well small celebration was push true! We was all happy, from the workers, boss and me also to see the months long work done! I am satisfied with the result, from design point the RedBox is the right thing. Happy! See here the first "studio" photos of the RedBox done in a hurry for flayers, shows and presentations! For next months in April it is planed the production start, it will be hurry again, I am sure!

Down Town Carnival 2010 Like every year, I had chance and I like to make photos of the masks joined Carnival chord. For this bunch I was focused more on portraits interesting faces. It was fun and pleasure to make this job! Enjoy like I was! Behind the lenses for you dr.Lojz

CNC Art patterns

2010-02-01T20:30:00.005Z

Working on some pre-mollds for Fire Box parts, I was take shots of this nice patterns. The 3D curves of the toll always fascinating me on the accuracy, form, pattern, geometry. Here I am share with you this patterns, enjoy as I, making them!

Micro FLY

2010-01-20T07:40:00.008Z

Let's go for a week or two back and "clean" whats happened on RC level. I was always looking to discover extremity on RC planes. The new Spectrum system allow now to build and fly /specially/ really light models. Light I mean 30g RTF. My fist touch with this micro level was the MicroFly1, good starting point for the future projects. It was build for a step too heavy because I was not able t get in short the CFK poles under the 1mm. The model is powered with 8.5mm brushed E-motor, equipped with Spectrum 6400 receiver /Thanks to Eric from http://solar-flight.com/ for support //, so the weight was around 40g. Way too much for this type of models, but still flyable! Here it is the "light monster" Some fly's was done on the backyard too. Here it is Luc trow the model! He enjoy as well! We was fly with Luc in the Town Castle hall, where the baroque architecture meet the hi-end technology, so goof feeling to fly around the hang light. Luc was made & fly with his freeFlight 8g creation on 1lipo and small electric motor. He reach the fly times close to 5min. Weary good! Then the second edition of the MicroFly2. The model was done for 10g lighter in construction, it fly weary good and I am satisfied with. The RC setup remain the same, the construction was improved! Th RTF weight under 30g, beautiful! Some test fly was done in atrium of shopping center! This will be never ending story, building and flying the models is something special!

Instrument plate

2010-01-20T07:05:00.005Z

Back on the route. The overnight project is on the schedule, well it is almost finished, at least from dr. side! The premold instrumental panel was designed, draw in 3D, in Alibre CAM module calculated the machining path and milled then on CNC. From the shape and construction not complicated piece, but important in Time schedule of the FireBox assembly. The piece was done from MDM plate it will be in next steps covered with epoxy and polished. Fromm then the mold will be taken! Here it is the piece on the CNC: This is 1/2 of the final length, somehow the Y axis is not enauht long to make piece in one step, who care, it is done! Dr. is back better then ever!

2010_1st One

2010-01-18T08:25:00.003Z

Dr. is back better then ever. The comp was cleaned and restored on new, all the reest is now history. Graphic/3D/CAM/Alibre run like a heal now and I am younger for 1monts, he he! The work is going on, I am happy to go ahead! More work soon here! dr.Lojz

System break down

-----------NO PICTURE--------- -----------any more---------

If you have ever had a virus on your pc, you will know how frustrating it can be. With pop ups occurring every second, file names being changed, slowness of the computer and everything else that it involves; it just adds up to being a complete and utter nightmare! But dr.Lojz wil be back soon, better then ever ;-) dr.

This is for this year the Christmas card, with all good wishes! Go ahead and spread good will around the globe! touch and go dr.

Santa Claus Air

2009-12-21T14:02:00.013Z

This December time is running true like a . . . . .

Somehow I come to idea to make this year the real flying Santa! Maybe this is the reason not to write on the blog, but I am back. Undefined flying objects are always difficult to realize, first tray was with 3D Santa, sleds, Reindeer and to be light as possible. Goal was under 500g. Santa was good pilot and Rudolf take for a power, no problem. Because of the box construction and strange aerodynamic I decide to build new one to be flyable indoor! I choose the "classic delta" wing wit Santa silhouette! Perfect, it is controllable, quite easy to fly and light! First fly's was done at indoor meeting, weary successful! And for the final, the show Air Santa was done at the volleyball game break. It was great surprise for the complete audience with music background and gym hall full of people. The drum supporters catch immediately the rhythm of the Jingle Bells techno background. Not too much space to fly, the volleyballs was flying around, but I did it! Show was great! Next show fly is planed for kindergarten surprise and some other events! The short video of the AirSanta will be presented here as well! Up to next time! dr.Lojz

Pimp up MC18

2009-12-03T08:34:00.009Z

Here it is another design project in my design lab, the remote control from 1990 is getting the new face! I was using this remote for the competitions which I stop in 1995. Three years ago the old MC18 was wake up again, it is still work perfectly, but in a short will be converted on 2,4Ghz, the new transmit-ion system. At the same moment the face-lift of the RC will be made! Here it is the oldy MC18 All over the years, from my point of view not so much was done on right product design of the remote controls. Well some high lights was presented and this is good. From the othere side more or less all the RC products today looking as the gaming devices. Lets make some serious step forward! Working on the new concept, it is in early stage of design development, but already on the stage to be presented! Here it is, the pimped MC18 on 2,4Ghz The design process is somehow on the middle of the way. Some more steps will be done and at the end the plane is to make the body with the Laser RP technology, which is at the moment the best way to make one/two parts from plastic! Follow up this space, will be fun to see what is coming out from the Laser reactor!

Bionic design

2009-11-26T12:25:00.006Z

The design process today take so many steps to do/thing/compare//made,

so we can say the design is interdisciplinary process.

I am not new into hydrofoils, it was some moments in my life which push

me forward a bit. One was for sure the try on Aquaskiper, great tool on

the water! There is no better feel when you slide on the water surface

with almost no power, gliding I mean! It is like sailplane gliding true the air,

like a bird, like a fish under water! YES that is!

In my past 10+ years I was spend a lot of time with kitesurfing,

starting in late 90', make me still fun to go on the water today. The hydrofoil

for the kite board was made.There was no hi-tech CAD/CAM and FEA done,

just go strait forward with the goal to glide on the water! Shapes come to my

mind was for sure inspire from the nature, on the design process we call this

Bionic design,

/more here http://public.beuth-hochschule.de/~bionik/BionicED.htm //

Well done here it is:

I was learn a lot from these geometry, it works well, almost too precise

and too powerful. It was crazy summer, with a lot of fun on the water.

Lets go back to Foil extensions for Moth. Here it is quite the same story.

Once I get the idea what to do, then is no restrictions any more. Drawing

table, pencil, paper on the first steps, then the comp is in charge.

Inspiration come for sure from nature, we can say bionic design!

It is simply like, if is enough good for the fish fin/flippers then is no doubt

anymore! Shapes which was created from the nature in the past evolution

are incredible. We can find a lot of answers there.

The Moth foils are specific, here we have the function/technology and

the shape, hand by hand together! I know a lot of today foils on the

moth have full span flaps and the question is why? It is driven by technology,

because any other shape is too difficult to made, or it is simply

development done step by step. For sure some kind of elastic flap

systems will be present in future, we need just to find the right

technology and materials.

And remember it was done years ago, by the mother nature!

Some nice Bionic designs, driven by hi-end technology are here:

Creative-bionic-designs

http://www.yankodesign.com/2009/06/03/ten-inspirational-and-creative-bionic-designs/

One nice step was done on transferring Whale flippers to the wind turbine propeller!

Picture currently from www.whalepower.com

This one and many others can be find over net.

The next step which make the hairs gray on the foils is connection in "T" corner.

As we all know any corner of two surfaces in aerodynamic or hydrodynamic

calculations made a drag. For example the wing and the body connection is

one of the biggest drag regions on the plane. It is the same on the moth,

of course it is! So on us is to solve the existing problem on the best way we can.

Here it is a lot of not academic know how to be read true:

I was throw some ideas in brain reactor already, the process is not
finished yet, but when the results come out, it will be published!

touch and go
dr.lojz

We did it, Aerotow of the best!

2009-11-25T14:39:00.002Z

One of side projects, not just for hobby, because I was learn making RC gliders, which give me a lot of knowledge from materials, technology and also to be patience, yes for a life!

Luc was made two foamies from a light Depron foam, he was enjoy like always to be creative. The electric motor plane is powered with 2s lipoly 700mAh at the weight of 150g, at wing span 800mm. For the sailplane he was take out the RC from Koaksial helicopter on 35Mhz. Sailplane is even lighter with good 110g.
He wish to proceed the Aerotow with booth creations. Last Saturday it was so far. I was invited to fly the towing plane, he was on glider controls. Well we was both a bit nervous but it works!
RC aerotow is one of the dificult steps on controling the models, booth pilots must to be simultan, precise and quick in case something go wrong!

Here it is the documentation ;-)

Moth hydrofoil elastic flap

2009-11-19T22:39:00.001Z

Moth boat on the foils is some how extreme from the sport and also from technical side. OK not only these some problems are from the hydrodynamic also!
Current world champion Bora Gulari come up with interesting and professional done video study of cavitation/ventilation on the foils.
Here it is http://www.youtube.com/watch?v=qDpnXsAB1oc

The discussion on the SailingAnarchy forums started,
http://forums.sailinganarchy.com/index.php?showtopic=98777 some good ideas and problems was discussed and here we have one answer to the foil
ventilation problem coming from the flaps gap!

Moth hydrofoil elastic flap

Elastic flap end or extension will close the gap we have now on some existing foils where the flap end before the tip of the foil! This gap is in any case the point where the vortex of water flow is presented. From this "mistake" on the flow we get then the ventilation and the cavity on the foils. Result NO foiling anymore, wet eyes and crash....
This small triangular shape with the flap section on one side and pointed as much the technology and materials give up, will be made out of day-cast elastomere in shore hardness A40-A55max, or even better made from two or three hardness. As I pointed the technology is open and here in Lab we are ready for this service on demand.

Code Fire Box Flyers

2009-11-17T07:28:00.001Z

There is no product without promotion material, a hard job for all of them who work in the sell department. In case of Fire Box the story is for a step different. This is not a public product it is dedicated more to small productions, workshops and fire departments. I was take over the graphic design and the page layout of the flayers. My goal was to present as good as possible the product, which not exist yet, to be well visual presented, with all clear functions on the board.
In all we have three systems the Powder, Foam and the CO2. On the first page they are all three together and then one by one, with all technical characteristics.
Again the power of Alibre systems was the right choice on the board. The best is to use the same 3D drawings of the parts for the renders too. All in one package and here are the results! The Flyers are done!

Step by step we are closer to the point to have this Blog up to date! Flyers survive the exhibition and fair!

Code Fire Box part II

2009-11-15T17:21:00.004Z

Back on the route,
the design process of the chosen "edgy" take a place. From the initial shape some parameters was changed, like the pistol can not to be placed outside in a gap like here,

The Fire Box get the 300mm wells for better handling on a ruff surfaces! Parallel on the polishing the "EdgyBox" the whole inside of the Box was drawn into Alibre parametric CAD.
Here it is the CO2 set up with 9 bottles of gas

Parallel with the "EdgyBox" I was take a variation of the design3 on the table as well, because the corner holders was solved much more better here then on design2!

So step by step to the final design, at some point the decision was made, we need compromise true design2 and design3! That's mean less edgy and more round shape will be the right one!

Again parallel the hard work was done on inside parts and renders to bring this pieces to the life. Here is one of the in between steps, the inside firebox pieces into the hangar! /no real photo just illusion and computer graphic//

The Box shape after close of the month work come to the final shape. The top is opening, the Z side cut remain, the corner holders was adapt to the best ergonomic shape and again we are in Hangar for presentation.

At the ens and also on the edge with the timing of the project some small changes was done! Not only in colors but also in dimensions, door placement, base of the box and so on! Lets take a look on the "final"
renders into the Hangar which was used for the flayers as well! More regarding Flyers later on!

In closer look on the last two designs you can see on the door the round shape box, this will be control box for the CO2 bottles! I was prepare the initial design for the control box as well, the design is not yet confirmed /15.11.2009/ and I will post here if we go forward with this shape or not!

From the beginning I was wondering how the corner holders will work in 1:1 measurement. Drawing on the screen is one side of the world and reality is sometimes different. To check the situation I was simply mill out of RDM plate the corner on the small cnc router in the studio lab. This works well true and we have for the first time the corner part into the real dimension!

At the last stage the final CAD drawings was done in AlibreCAD and the solids was send to CAM workshop to mill out of the Ciba Block materiel the pre-mold shape of the whole box! Two shots more from the screen, the wire-frame image of the box and the solid one!

More of this and closer look on the 1:1 box next time!

Code Fire Box

2009-11-13T19:33:00.000Z

This pages must content some design work as well, otherwise it will be not here! The world is turning and I honestly believe into good will also on work side. I was at end of August invited to work with the project group on the new Fire Box set up. My part on the group will be the product design. Timing like most of the time in my job was short, less then two weeks for the first propositions, just standard design process on my drawing desk! The task was clear, make new design for Fire Box! The parameters are LWH 1200x800x1100mm, so eurobox top view, to go true 80cm door! Here are the design propositions and presentation for the company! This was the design presentation to the company, on first meeting the edgy-Box was chosen for next steps. Now some real work can begin. Into next steps of projecting the 3D CAD was use and photo renders for illusion of the real product! In next posts we will follow the whole process of design. I was take over to prepare the Flayers of the product which doesn't exist, magic touch is here! More later!

Moth hydrofoil extensions

2009-11-12T20:44:00.000Z

I am connected to the nature, air and water are my elements, this is for sure. From the early beginning making the boats models, then RC sailing and at the end my connection to the kitesurfing / www.seajump.com / Over last years I was flowing the Moth sailing class, which I find weary interesting! The whole story went so far, I was buy a Moth this spring! Yes Moth on hydrofoils come to my place late April. Here it is first time on the lake! Some nice sailing days I spent over the summer, but this crazy machine need 10-12knots wind to come up on the foils! The spe of the main foil and the tail is squere, this is bad hydrodynamic solution. I was looking already over summer to change and make new foils, doesn't happened true the lack of time! Axeman 7 GBR 4067 on the foils, it was hard this day because the wind was strong in gusts up to 30knots, well to much for this boat! The story for today writing is different. The decision was Axeman need new extensions on the foils. In vision to have more performance, less drag and earlier take of, I go for it! In short, there was couple of steps to do. First find the foil sections, then use the CAD, in my case the www.Alibre.com! Working n the foils sections and shape. Solid was constructed on the 1/2 size of the foil. On next steps some surface check was done with the mesh elements. Logical step forward go to CAM, here is the first milling path, and the finishing steps! A quick jump to the lab, use Carbon fibre material, vacuum and we have first two extensions out of the mold. //OK OK, it is not so easy, but I am lazy to write!// Like every piece done from Carbon fibers looks great! Here they are finally assembled on the existing Axeman/Fast-craft hydrofoils Don't ask me what is next step is ........ sure go to test them, the extensions! The only problem will be the air and the water temperatures on North Adria. Water have today around 15deg C and the air the same. Goal is to be on the water for next week, I hope I will make it! In all I am still not sure if these extensions are just modifying of Axeman or it is beginning of designing the new Moth! I will see and post here what the future will show! Next time some more design news!

Tailless gliders history

2009-11-11T22:44:00.000Z

For the first steps I like to clean for a bit the history! So where to start, lets take a look on my big love the RC Tailless gliders. A huge development was done over more the 10 years on his activity. Itt was a lot of falls, but also good competitions wins! Good fell anyway! Here they are, from free-flight to full Carbon Mystery II, all together!

2009-11-11T21:57:00.000Z

Somewhere we must to start.This Blog will bee a good mix of Creativity, Design, Technology, Sport and yes, sometimes a truth of life! As dr. James wrote once for SEAJUMP kiteboards, I will past and copy his words about. Because dr. James is dr. Lojz thats true and simply. I was found the Seajump name in late '90 from then up to now nothing change. The brain lab still works with full power and results are outside in use! So as dr. James says:

Seajump - what is it?

It is all and nothing, but above all it is a deeply rooted stubbornness. Once it was a vision, and it remains a vision. It is our and your soul that drives us forward. Seajump is always one step ahead of time and never follows the herd instinct. We have an excitingly strong and well equipped laboratory for performing and studying brain flips, which are subsequently intravenously injected into the evolving products. The transfer of molecular vibrations is achieved using a development reactor, from which the spatial form is then created. We are also able to clone our products, but at the same time we aim to upgrade and further develop them. Obtained reflected frequencies at forums and spots are vital for our further research and development. After every successful project completion, we move to a secret home-spot and enjoy! Our laboratory staff consists also of the special group of psychoanalysts, who are dealing with too powerful brain waves of our selected specialists, whose brain vibrations must be adjusted to a normal level as prescribed by the national health service. Our research results are being used by several market leading sport companies in the world, located in various climates from cold Switzerland, hot Hawaii, to wet Britain. So much about the laboratory and the reactor.

Regards, Dr. James
