Mini Maker Faire Lyon 2016 soldering contest results

26 challengers participated to the soldering contest which took place during the Lyon Mini Maker Faire 2016.
They used 8 to 50 minutes to get a Starter Kit up and running from the PCB and parts !

The winner did it in 8 minutes and 16 seconds (35 seconds quicker than me!!!) ! Spectacular ! He won an USB-to-UART Adapter with which he will be able to easily program the micro-controller on the StarterKit, and communicate with his next Maker projects :)

We didn’t have time to take photos, but you can tweet yours @TechnoInnov (#MFLyon) :)

For the participants, you will find most information about your StarterKit on our dedicated page, including schematics, KiCad sources, and many more useful information (this is open Hardware :)

For those interrested in programming the micro-contrôleur, you can reffer to the paper from Cyprien Laplace published in Open Silicium n°17 : “Utilisation du SDK Mbed sur un tout petit micro-contrôleur LPC810″ (pages 60 to 63, in french). This will get you on tracks and you’ll be able to re-use your Starter Kit in your next Maker project !

Thanks for your participation, and well done to those who gave it a try :)

Dev update on October 26, 2015

We promised a quick update on the current developments, here it is:

More than the first prototype assembly, here are the (mitigated) results of the first tests :

The photos are available in this directory or below.

The strange red coating is an isolating warnish, which I thought I ordered the transparent version … obviously it’s not.
Anyway, this highlights ths result of the first connexion to mains : a bright flash !
Of course, you only get the calcinated result …

The next four pictures show the first CPL communication tests (Power line communication) which let us validate the USB version of this new communication module, and the remaining part of the PSMC (Power Supply Monitor & Control) adapter board (the one which did not burn).

And the ones are mechanical tests for the CPL module in DTPlug format (UEXT connector).

PCBs for version 2 (v0.2) or under production …

by the way, we tested and validated the isolated DMX module and the Thermocouple adapter board.

The isolated RS485 module will follow, as the DMX protocol uses an RS485 Bus, we only have to change the connector.

Mind that this is one of the few isolated RS485/DMX modules available, at a price sometimes lower than non isolated modules …
Needs a box though … it’s on our todo list :)

Dev news, October 2015 update

Hello World !

A small post to give you some information, but also to publish an idea, in order to protect it in the easiest possible way (So please, tweet, share, and forward this !).

We are working on a new module for the DomoTab system, which is not a communication module, but a control module. This new module is able to control a load (one or more devices) and at the same time measure the current used by this load.

This control module requires a communication module to operate, and thus uses the connector we defined for our communication modules.

The solution we selected to drive the load allows for both usual AC loads and also DC loads. It is also possible to modulate the power for the loads which may be controlled in this way (water heater for example).

When used with specific sensors, (temperature, humidity, …) you will be able to match power usage with local power production (solar, wind, …) or specific time frames (for noise reduction or electricity costs), while observing one or more thresholds for each operating equipment (maximum temperature for a fridge, minimum temperature for a water heater or a room, room humidity, ….).

This system will also allow you to plan or shift the power usage of some appliances across the day or (even days) depending on planned local power production or electricity costs, either using local data (luminosity or wind sensors, manual or automated programs, …), historical power production data, or external data (weather forecast, planned electricity costs, …), or even all of these data.

We will provide more information as soon as the first prototypes have been produced, which is expected soon :)

Some news

We told you about three months ago that we started working on the DomoTab project once again, and despite the vacation break we made some progress.

You may have noticed with the technical page for the RF Sub-1GHz module going online, and the related user manual for the USB version of this module, or the epaper support added to the modules.

There also has been a lot of work on the module code, with new examples, a new directory structure to get all modules in the same GIT repository, but also a first commit of the DTPlug code, and some work on the protocol to comunicate between the DTPlug (or any other host) and the modules, which is already available in the modules GIT repository :)

And last, the tests of the KNX module are going on, we will post some more informations on these later.

Stay tuned :)

Epaper support test video

Second video for this busy day, shorter, which presents the support of e-paper screens from Pervasive display via Embedded Artists adapter board for our GPIO Demo module or our LPC1224-BreakOut board.

Both images or in the micro-controller flash memory, and the text is displayed when it is received on the serial line (USB-to-UART). Pressing the user button switches the images and then restores the display of the text.

Text display is made using partial screen refresh.

One more step toward our multifunction “smart” control :)

Video about MWL project during Innorobo

Hello Everybody !

Here is the link to the Video made by Sébastien Meunier (in French) during Innorobo 2015 for France télévision (Méta Média).
The video presents some parts of the 1/87th scale Car-System we made for the Mini World Lyon project.
It focuses on our prototyping platform made using common prototyping technics as found at YouFactory or in many other FabLabs.

Paper 5 now online (in french) on Techno-Innov’s Wiki

The number 15 of Open Silicium is out, so it’ time to publish the paper which was in number 14.

It’s done !

For the curious ones who want to understand what’s behind IDE like Arduino’s IDE, this article is a good start.

You will be led through the required steps to get the usual “Hello World” in it’s micro-controller version: tunring ON a led. Hey, don’t ask for too much, it won’t blink yet.

This paper will be used for the courses during UDOS on Friday morning (July 10, 2015): Discovery of a micro-controller “from scratch”: getting inside, or doing it the other way (from arduino).

A place on YouFactory’s booth at Innorobo 2015

We spent the first three days of this month on the booth provided by YouFactory during Innorobo 2015

Thank you to Pole Pixel for the booth :)

We presented some projects for which we used technics and production tools available at YouFactory:

  • DTPlug’s box, which went through validation stages using 3D printing (hot wire) before mold production.
  • Prototype model for the car system development for MWL‘s huge, 300 square meters, model, built for a permanent show. It has been made using laser cutting.
  • Prototyping and production of the charging stations for the vehicules, also using laser cutting.
  • Prototyping and production of the chassis and front steering assembly using 3D printing, but with resin (Using a FormLabs Form 1+, which produces finer details.

Also thank you to the event organisation team :)

A new start for the DomoTab project

Hi all,

We have been very busy for about a year and a half on a customer project, and thus unable to spend much time on our own project, but here we are, back and as motivated as ever, as there have been a lot of feedback and interest from all of you about home automation and the Internet of Things (IoT), but with respect to privacy, DiY, and free software

At first, we will spend time on writting the documentations for yet undocumented products (RF module and DTPlug), both as PDF and on the Wiki, and then on adding examples and software support for all of our products.
At the same time, we will go on with the development of the KNX, 1Wire modules, and start a few other modules : CPL (Power Line), BLE (Bluetooth Low Energy), and 2.4GHz RF for support of the 6LowPAN protocol. Each module should come as USB, UEXT and standalone as for the RF-Sub1GHz module.

For the most curious of you, the other project we worked on last year was a car system and animation system for Mini World Lyon.
We will create a one-pager to showcase what we did, and try to sell the result either as a whole, or by ourselves, which would need some more time to create end-user oriented versions of the system, as the customer decided to keep a simple licence rather than buy the whole intellectual property.

Technical documentation and product page for the LPC1224-Breakout Board

The Technical documentation for the LPC1224-BreakOut board is now available!

New paper in OpenSilicium 14 : Program your GPIO-Demo module from scratch

Open Silicium

As we promised to you, we managed to close the next paper soon enougth to get it in Open Silicium #14 !
It should be available in your favorite book store in a few days (in France). If not, consider fiding a new favorite book store !

Much more than a guide to GPIO Demo module programming, you’ll find a step-by-step how-to which will guide you to the depth of these small black chips you can find in an ever-growing number of everyday-life items.

Don’t wait for them to crush you, get ready for the trip and understand their deepest internals to master them and get the most efficient code for your projects.

Lower prices, new modules, new licence, and wiki launch

This new year brings good news !

First, we lowered most of the prices on our products. Have a look to our store. This is mainly an adaptation to the market prices, hopping it will help us sell more.

We also put our new RF-Sub1GHz modules (868/915MHz) in the store. These are available in three declinations: UEXT for the DomoTab project, USB for development or use from any device which has USB host ports, which opens many other use cases and makes debugging easier, and last but not least, the standalone version, which can be powered from a simple AAA rechargeable battery (or anything above 0.9V, so some simple small photovoltaïc cells may do, to be tested).

For those interrested in the LPC1224 micro-controller but do not care about the UEXT connector or DomoTab modules format, the new LPC1224-BO development board is now on sale. It’s a simplified version of the GPIO Demo module.

Another piece of news which should make many of you happy: some of our products are now under CC-by-sa licence.
This change affects the GPIO Demo module, the brand new RF-Sub1GHz modules, and the LPC1224-BO development board.

We launched (at least !) our wiki, though there’s not much there yet (appart from the previously published papers for Open Silicium, and mainly in french, but we will add content in the upcoming weeks and translate what is already there.

And last, for those interested in the micro-controller software, sources for our modules have been re-organised so that support of new modules and exemples for existing ones is easier (using git branches for each module, easily sharring common code).

Documentation update for GPIO Demo module

The technical documentation for the GPIO Demo module has been updated for the v4 of the module.

Ths sources (software) have been improved to make examples or applications creation and use much more practical, and use branches from our git repository to support new modules, including the brand new RF Sub1GHz module (868MHz/915MHz) (prototypes have been tested and validated !).

We’ll try to go on with this pace and get the documentations for all the other products done: DTPlug, USB-UART adapter, but also RF Sub1GHz module and LPC1224-Break-Out board.

Open Silicium – paper 4

Open Silicium

The fourth part of the paper series on the making of of the GPIO Demo module for the DomoTab is published in Open Silicium number 13 !

One year has gone since the previous one (sic) but you now have all the keys to get from design to production with professionnal-like quality while keeping costs very low and with very limited tools.

I give you my word, we will not wait that long for the next one, and programming your micro-controller from scratch will become as easy as your daily programming tasks before summer !

lpctools made it into Debian GNU/Linux

Hi all !

It has been quite a long time since the last piece of news, but we’ve been busy with other projects for our custommers.

Anyway, we keep going on, one step at a time, and the LPC1224 micro-controller support is getting better (it’s the micro-controller we use on the GPIO Demo modules and which will be used on all of our module if possible). Another module is ready, but not it’s documentation, so it will not be on sale till this is fixed, but here is the one piece of news we wanted to share with you today:

lpctools is now included in the Debian GNU/Linux distribution !

In order to get things done we finally asked Freexian services.

Next step : resume the redaction of the papers on the Makin-Of of the GPIO Demo module for Open Silicium. The fourth paper is written (under rereading) and I’m working on the number 5, but it’s growing too fast and will certainly be split in two parts.

Open World Forum 2013

Hi !

As some may be aware, Open World Forum 2013 will stand in Paris from October 3 to October 5 2013.

We spent the last two weeks on the design of a soldering introduction kit that would be more attractive than a simple led blinking assembly, and mainly trying to solve all the problems arising when one tries to create a new product with a very close deadline (3 weeks !), a very short budget (nothing for the design, and very limited “per kit” budget): components availability problems, last minute changes, production delays, …

Anyway, we created a soldering introduction kit that will then become an ARM Cortex-M0 micro-controller development kit fot the DIP8 package version of the LPC810 (the big one, easy to solder, which you can use on breadboards). But NWP changed the chip status from preview to production … with a production hole of one and a half month. Of course the remaining stocks were bougth before we learnt about this problem, and we had to find an alternative. In order to keep the main idea behind this, we chose to use the bigger brother of the LPC810 : the LPC812. Same silicium in a smaller package with more pins … in a surface mount package … which had us creating an adapter board.

in short, PCB are in production, we ordered the components, and all should be delivered in time for the forum.

And for those who won’t be there, no worry, we had to order much more than planned for the forum to be able to get within the budget, so this kit is available on our store at a very low price for such a product: 6€ TTC (without shipping).

Of course, this is for the Open World Forum, so it’s Open Hardware !

The next part of the paper published in Open Silicium number 7 is available in number 8. One could say that’s pure logic, but this time it’s not one, but two papers waiting for your eyes !

The first one (which is the second one in the series) introduces some addons to the schematics, while the second (or third …) moves to the next step and guides you through the steps of the PCB routing process, and of course, using KiCad.

You should not wait to get your hands on it then, or you can keep it at hand as a reference for pcbnew usage, the tool from KiCad suite for the routing process.

Ulule crowdfunding target reached

This evening the crowdfunding campaign we set on Ulule reached (and overshot by 6%) the initial target we fixed (as of 25th July 2013) !

Many many thanks to all the people who already supported our project !

Of course, the crowdfunding does not end here, and we can go beyond the initial target. If the 5000 euros level is reached, we will send an additional gift to all those who selected a reward above 35 euros (the gift will be in relation to the selected reward).

But we can go much further, and if the 10K target is reached, then everyone will get an extra gift as we will then liberate the GPIO-Demo module, removing the commercial use restriction from the CC licence.

If you did not support us, time is running short, the crowdfunding ends on 30th July 2013. After this date, the “bellaminettes” which “Bruno Bellamy” made for this crowdfunding will become forever unavailable.

Smart control

After some brainstorming we can tell you about a new project which should be out soon : a new kind of smart control switch.

What is a smart switch ? We’ll try to explain.

Look and feel

This control denotes from classic ones from the start due to its simple look and lack of mechanical parts. It’s a single square or rectangular plane, somewhere between 3 and 5 inches (might be bigger, be more expensive then, or smaller, but harder to use).


If there’s no mechanical parts, then there’s a touchscreen ?


Our new control will use Nemopsys technology, and thus be touchless ! It will detect your fingers or your hand in 3D and you won’t fear scratching the surface with your keys when you turn the light on. It also makes it independent from brightness, temperature or gloves !


Then if it’s a single plane, how do I know where to “push” and makes it smart ?

We will use e-paper technology to allow a very low power display (No power used when display is static !) and get an interactive surface, making the control “multi-function”, allowing immediate feedback or help display.

As an example, the surface can display a picture of the whole room with each light identified with a status indication, making it easy to turn on or off a particular light without going through all the switches on the wall.

And what about controlling the shutters with this smart control. Let’s say you want to lower two of them. Select them, slide your hand to the position you want, and the stores will obey to your needs :)

Got it ?

When then ?

Soon !

We are barely out of the brainstorming step, but the design is not too much complicated. We will keep you up to date :) (Follow us on tweeter or google+ !)

Video for GPIO Demo module assembly process

Yesterday we filmed the assembly process of the GPIO Demo Kit and the video is now online !

For those interested in the “Do It Yourself” way we created a demonstration module which uses NXP’s LPC1224 micro-controller used on all of our home automation modules, and it is available as a DIY kit.

Our goal is to demonstrate that everyone can produce boards with CMS components at home with very few technical means, and for a reasonable price (We are selling the full kit for 32 euros TTC).

You’ll then be able to use this exprtise for your own projects, as many comany propose online PCB production services for low rates, components or available from different online distributors, and the laser cutting technique gives very good results for CMS stencils :)

You will find the papers we wrote on the “Making Of” of the GPIO Demo module in the Open Silicium magazine (the first part is in the number 7, page 38).
These papers will help you with your own module creation, from concept to embedded software programming.

Our 53 minutes long video covers the whole module assembly, showing every step, possible pitfalls and how to avoid them, and how to right eventual mistakes with very few specific knowledges or sofisticated material.

In short, the modern, miniature electronics to everyone!

Open Silicium

We wrote a paper for the magazine Open Silicium just published in issue 7 :)

The paper is on page 38 : “Électronique et domotique libre : conception d’un module pour le DomoTab avec Kicad” (Open electronics and home automation: design of a module for DomoTab with KiCad).

Do not hesitate to buy the magazine (it should be available on newsstands shortly), or subscribe online :)

Schematics sources from the paper can be downloaded here:

The “RefCard” is available on our wiki. The version covers all written papers, so there’s more than what is in this first paper.

This paper is the first part of the “Making Of” of our GPIO Demo module, and covers the first part of the electronics schematics, but is also a tutorial for KiCad, a very good electronics CAD free software.

We also wrote the next two papers, one on the remaining parts of the schematics, and one on the PCB layout.

More papers will follow : DIY assembly of the module and embedded programming “from scratch” for the micro-controller.

This first set of papers will be followed by papers explaining how to extend the functionnalities of the module, for example to create a weather station, or control a pluged device’s power.

First batch of mass produced DTPlug boxes

We received the first batch of mass produced DTPlug boxes this afternoon from the injection moulding plant in California (USA).

The 17 shipping boxes take up a lot of space but we’re happy to see the fruits of a project we’ve been involved in for so long and we’ll finally be able to start selling those DTPlugs :)

We’re slightly disappointed by the quality of this batch which is a bit bellow that of the pre-series but nothing to worry about, it’s still good enough to keep the dust out :)

Ulule campaign launch

Let’s go!

The Ulule campaign is on !

Ulule is a micro-financing website allowing people to support a range of projects and get goodies depending on the project and their contribution.
We have chosen to sell the GPIO-Démo module (in kit) and to offer discount vouchers for our shop with no minimum contribution (other than the value of the voucher), and no time limit. And for the quickest, we offer online training to get started on DomoTab modules or learn to create new ones, either for DomoTab or your own project!

New processor module

We just received yesterday a new processor module for the DomoTab, with modifications to the DDR3 bus routing and this time DDR functions seamlessly.

I can’t tell you more about it yet, I’ve got to test everything else and there’s a lot of stuff around this module so it’s gonna take some time but at least I can get started!

I’ll keep you posted as soon as Linux boots but for now, here’s some eye candy:

Laser cut CMS stencil

This afternoon I tested the laser cutting CMS stencil technique at Lyon’s FABLab (Fabrique d’Objets Libres), that will be used to build the development modules. These stencils will be part of the development module kit I’m working on: an autonomous module allowing you to test your boards before building them.

The plastic stencils (rhodoïd – 150 micrometers thick) work great, at least as good as steel ones and are perfect for laser cutting. Tin sticks well to the PCB once the stencil if removed and transparency makes positioning easier.

You need to watch your pad size though, due to the cutting width: as much as 40% smaller for CMS components in CMS 0402 boxes, SOT-363 boxes or even LQFP boxes like the LPC1224′s otherwise you’ll get shot circuits.

And now, the pictures:

DTPlug box pre-series for mold validation

Hello everyone!

Just to tell you that we received the first, fresh from the mold, DTPlug boxes. The rest is still in production. These are for mechanical validation of the mold. Except for a few minor aesthetic details, they meet our expectations :)

Here’s a few pics:


With Friday’s delivery of boards (test in progress) we’ll soon be able to deliver our first products, so order yours now!

JDLL 2012

JDLL 2012 are now over.

Thank you to all the volunteers of the organization team, and to “Maison Pour Tous” for their hospitality.

You were many to come ask us at our booth, and our project has obviously aroused great interest among all. This allowed us to validate our technical and commercial choices, and shows us that freedom is the right way.

We hope that you will confirm this by actively participating in the Ulule crowdfunding campaign we are setting up for pre-sales of DomoTab, to reach a production volume that would significantly lower the sales price.

We also sold the first DTPlug at these JDLL, which is a good sign and we hope that some more will do so.

Now that our site is online, we will continue to keep you posted here, and through our Twitter account.

JDLL contest results

Hello Everyone, and thanks to all those who participated.

Well done to the winners of our JDLL 2012 contest who found which bug “tibug” stands for: an ant, a small yet tireless and inquisitive bug which lives in community and work in groups, and for which sharing is natural.

JDLL contest

Mug tibug


Try to win a “tibug” sticker (50 first good answers) or one of the two “tibug” mugs involved. It’s simple, answer the following question:

What does our “tibug” logo stand for ? (Edit: answer is now here)

Warning, the question is about what is symbolised by the logo, not what is used to represent it (a capacitor, a chip, and a led). The answer is short and has to be specific.

Contest rules :

  • Open game, with no purchase requirement.
  • Limited to one answer per physical person.
  • Open from Monday November 12th 2012 to Saturday November 17th 2012 at 10h00 (JDLL openning)
  • Rewards will be given to the participants only during JDLL 2012 event (17 and 18 November 2012).
  • Data gathered during the contest will be used to send you information emails about the DomoTab project.
  • According to the law, you have the right to modify or request removal of your personal data from our databases.

Techno-Innov at JDLL 2012

Techno-Innov will present the DomoTab project during JDLL 2012 on 17 and 18 November, in Lyon (Maison pour tous – Salle des Rancy)

For the curious ones : global presentation of the whole DomoTab project, display of the first prototypes of the DomoTab control unit and it’s variants, and pre-sales of the DTPlug (Modular home-automation bridge).

Of course, if it happens at JDLL, it’s because the ahrdware is open (licence Créative Commons – CC-by-sa-nc) and the software “libre” !
