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 Ultimaker to make it all happen.  

Special thanks to JB and Lionel, indefatigable spirits with whom we worked together to make the 3d printers work horses again!

carbon fiber 2nd generation « WHO » with « FMTTM » sound track set up, and tea with round and square teapots.

Installation details: 

The teaware all have meanings –  Chinese philosophy of « round » and « square » via tea set.  We should conduct ourselves with Round and Square in mind, the great man said.  Round on the outside, Square on the inside : a Chinese principle of how to be a human being – be round on the outside (to not enter into conflict) and straight, non swerving in the inside (to maintain whats right and whats wrong and not bend) The Square ceramic teapot came from recycled objects of faclab.  The round stainless steel electric pot was sourced in Shanghai.

Setting up day at LaVillette





the FMTTM software maker: Mr. Etienne Durand






















Adorable curious school children on Friday morning, accompanied by their teachers.  They touched, asked a lot of questions and came back for a second time – giving explanations to other children!!




Square teapot, just the right thing to have for our presentation.  A round electric pot and a square ceramic pot.  This pot is in a traditional regular homefolk style (different from literary, or palace ware styles).  Very pretty green.  The form is DunHo – thick and stable – slightly Zhuo – pure+primitive.  The handle is beautiful well made.  I think its not a Chinese pot, but a pot made in Vietnam in Chinese style?  To be verified.  Stay tuned.


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.

The « Friend » series small cups.  With a little hand offering a gentle touch.  A link.  One visitor said, when you feel lonely you have this little hand to accompany you.  haha.  I didnt think of that.  The hand was made in Virtual World by a mysterious friend.  I exported it to physical world, here it is, the hand is everywhere.  Faclab is a above all about being social, hands reaching out.  :)

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.


question on PLA material is it food safe and what finish to use?

Ans :  All finishes are food safe when it is cured.  (takes one week for eurathene, and also lacquer depending on humidity and temperature)

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 exciting event, with a lot of young creative people – everybody seem to be in a permanent high.  Children, young adults, adults, retired engineers, everybody is so peppy and interested.  Many adults came and asked about the musical instrument, but children ask and touched the instrument immediately.  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 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!  

>There were fancy model boats with a large pool for testing, playing.

>Green house with monitors drops and special accoutrements for green house planting

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 construction tool?

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

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.
