Participation to Open World Forum 2013

Open World Forum 2013, the first libre and open source european forum takes place this year in Paris from October 3 to October 5 2013.

We will be part of the “Experiment” section with our GPIO Demo Kit, to demonstrate that modern electronics is accessible to everyone !

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!

Showcasing DomoTab for Imaginove

This afternoon we had a display of the DomoTab project during a Think-Tank organised by Imaginove at CPE-Lyon.

Thank you to Fabrice Jumel (research professor at CPE Lyon) for the contact, and thank you to Imaginove for the proposition.

It has been a great exchange time with the audience that I thank for their listening, participation, and interest.

The showing should be available on Imaginove website soon.

Join our IRC channel

You can get in touch with us on our IRC channel #domotab on irc.freenode.net

English version on air !

Hi all !

Our website is under translation, and as most of the content is translated, we activated the links between both versions.

You’ll certainly see a few mistakes, as even if we asked some help from my cousin who speaks english quite well, we translated some pages on our own.
The bad ones or ours :(

Please report any mistake you spot here : translation _ at _ techno-innov _ dot _ fr

Thanks, and have a nice time discovering our project !

Keep in touch by following us on twitter or google+ (links on the right), or send us any question at our contact email address (contact@….)

Sources for the schematics from Open Silicium n°7 paper

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).

Links to the sources for the schematics are in our post A paper in Open Silicium n°7.

A paper in Open Silicium n°7

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!
