MakerFaire Paris 2017 - Carbon Fiber guqin 2nd generation "WHO" - FacLab

MakerFaire Paris 2017 - Carbon Fiber guqin 2nd generation "WHO"

Now that the MakerFaire Paris 2017 Event is over, time for a report.
The event for me is a work-in-progress, as an experience.
First time at a Maker Faire, the setting is fabulous, such high ceilings with real vintage planes and double escaliers that ascends into open atrium gallery and lots of natural light, glass, everything airy, enhances the MakerFaire DIY spirit.  Everything is possible here!

First of all, a huge thanks to Professor Laurent Ricard, Head of FacLab of University of Cergy-Pontoise, who graciously lent me their 3d printer to make it all happen.

Sound tracks of "fmttm" 2005 :
Flowing Water (Guang Ping Hu), Pale Ink (digital guqin interactive instrument software), Zebrafish ( digital guqin interactive jukebox), and one random pop track (weirdo music com) : 
1 cycle = 15mn approx
4 cycles = 1 hr approx

First full impression of cf qin WHO embryo - assembled - will upgrade, stay tuned...

At Makerfaire Paris 2017 - set up

Setting up day at La Villette, Cite des Sciences.

Head piece printed


Details :

Tea/ sake cup, "Friends", inside finished with Polyurethane (transparent no color), or natural lacquer (black).

3d printed tea/sakecups treated with lacquer, a lot of people asked about this.  What is lacquer, is it food safe, where to buy it.  

I think people are curious, but maybe not many would want to drink from such a cup.
They would worry about food safety.  
So, in the end, maybe better to put urathane, a transparent, recognised material to seal the PLA cups.

DIY makefaire

I have heard about the Makerfaire for a long time now, and by chance, I am here too! 
It is not really a music instrument maker fair, but it is a DIY fair, and I saw one other professional guitar maker displayed his guitar at FacLab Cergy Pontoise stand.  Very beautiful.  (see the guitar in the video :

Very energetic, exciting event, with a lot of passionate young creative people - everybody seems to be in a permanent high.  Children, young adults, adults, retired engineers, everybody is so peppy and ready-to-go.  Many adults came and asked about the musical instrument, but children ask and touched the instrument immediately.  One visitor had a carbon fiber violin with him, he asked about the carbon fiber guqin in detail.  Too bad I didnt have a photo or video of him.  I would have asked him more about why he choose to use a carbon fiber violin, and whats the advantages etc. and have him play a short tune if possible.  He was on his way to do a concert.  Next time, I will not miss !!

People also asked about 3d printing, lacquerware teacups.  Many inquiries.  Met many makers, faclab people.  Very gd exciting ambiance.  My stand is probably one of the few that has a quiet installation.  Its meant to show an ambiance, quiet, and restful.  Soft guqin music plays our FMTTM software.  An original software that plays guqin music 24/7 using a random algorithm custom made from a guqin sound database.  This was created in 2004.  Here, because of the setting, we play the cd from the computer to let visitor get a sense of what kind of music the guqin instrument makes.

The excitement of DIY is definitely a very bubbly one.  (See video link below.)

This reminds me of the Secondlife virtual world ten years ago, everyone bothered to enter the virtual world is so excited and engaged in what they do.  The most beautiful objects, creations are - always - the ones you made yourself.  Its the DIY spirit.

Makerfaire is about DIY, from coloring books, leather money purse, guitar, fine wood crafts, 3d printers, plants, automatic robotic works, inventions, sewing embroidery machines, drones, recycled music instrument making, digital fridge hacker for beer making, crowdfunding associations, extensible 3d printers, many fablabs, electrolabs, adruino workshops 800exhibiters, and over 10,000 visitors for the 3 days event.

Whats so fantastic is that todays makers exhibit along side early vintage airplanes at the Cite des Sciences, huge high ceilings and endless escalator in the atrium.  

I have been thinking about sculptures, traditional and contemporary, participative type of artwork, performances, robotic algorithm paintings/ drawings, softwares that does your portrait online for free, 3d printing sculptures with or without algorithms, and old school hand made objects, stone cutting, wood work.  

What is sculpture in todays high/low tech world?
What is the purpose of sculpture?  Has it changed?  Does it elevate peoples spirits as in the old Beaux Arts days?
What about giving people pleasure to express themselves?  Arent all arts and crafts a little like that?  The users express themselves via the things they surround themselves with.

As for the expressive pure art, we were all taught that art is not useful, its mainly to express the inner joy/turmoil of the artist (who represents in someway his life and times with some honesty.  They are the ones who dare to say whats not spoken/heard easily)  

In todays world, is it still somewhat like that?  Are artists kind of a "saint" still?  Or has artists been "poisoned" into thinking that?  

Here in this MakerFaire Paris event, even though I have thought a lot about everything, I will limit my report directly to what I have seen and heard, and enjoyed.  The rest will be explored in another text.

High lights :

I have filmed a 58mn video - a walk through on my floor - so we could see the ambiance and content of the MakerFaire.  What an energy, the results of DIY!  

This video will be uploaded to Youtube and Vimeo
(Video seem v grainy, audio is little harsh, unlike whats displayed on my Playbook - so please just watch roughly to get an idea.  Will make a better video next time.)

Digital Guqin Art Museum first work in progress:

The carbon Fiber guqin 2nd generation "WHO" was constructed in the virtual world of Secondlife.

Using ready made Prims from prim machines, it was a fun game like work.
The difference between construction in a gaming virtual world and a straight forward 3d software is that of "play".  Its a bit like using Tinkercad to build a real bicycle.

Question: Could we make sophisticated real objects from tools of a virtual world platform, using basic simple construction softwares?  How good could the outcome be?  If we export the creation into the physical world?  We have many creators who build fancy constructions outside of the virtual world and import the whole work into the virtual world.  That is standard.  What if some silly person want to play in a gaming fashion and get it exported for real?  Like using Lego blocks to make a real video camera?  Could it be fun and sophisticated and useful.  How sophisticated?  What level of finesse do we need.

An important point in using software to build models, most of them are numerical, high precision.  If we use mathematics, it has a precision thats very close to industrial design. If we build the model simply by eye balling, the outcome looks handmade!  Even though its made in a digital way.  For something to look hand made, it must not be very exact, very precise.

Could we have a hand made repeatable arts+crafts object, that does not look like a factory output.  I want to have the hand made look.  That is why I choose to use Linden Labs Prims method for simple constructions.

What are the limitations of using this very simple construction tool?

Carbon Fiber Guqin "WHO" is the target output and as a kind of test.

Some photos

Left over filaments

Duck feet: normally this part is considered as accessory made in hard wood, but we could also make a massive carbon fiber guqin if the material is acoustically fine and strong enough.  So the WHO will be getting bronze feet... 

Netfabbfound this perfect cutting tool and for reparation of model files. 

For cutting up and repairs of virtual models - this is a free software, very useful when you need to print large objects with a small machine.  And all machines will become too small sometimes.  I found a machine with Unlimited Z axis called the "Z-Unlimited" by Rooie Joris.  See example here.
which was designed for Ultimaker.  It has a very clever support system as the printing height goes up.  With thin supporting threads to hold up the verticals as you go along - like the Malaysian tree with accompanying vines growing up 30meter and more together - once printing is done, you cut the threads off and the traces of the support are invisible.

Would like to try that next time to have the whole qin printed all in one go!  I found that for now, at the design testing stage, its good to have pieces around 5cm tall, big pieces are not recommended, because you have to change things as you go along.

Original Makerfaire Paris 2017 poster:
I have only time to do some of the items on the poster.
I have printed out a version of the cf WHO embryo.
There are maquettes of different tea cups different hands, they will be shown next time.

However, the 3dprinted embryo is an actualisation of phase 2 of xyzQin research-creation.
These will all be ready in due time.

Hashimoto (reknown silk string maker) looked at my video clip played by Peiyou Chang, and said :
He heard big sound and clearly, Your guqin is good sound too.
