Open World Forum 2013 – Follow up


L’Open World Forum took place in Paris from October3 to October 5 2013.

Eventually, we received all the parts in time so you were able to make your own badge and try you soldering skills.

For those who were unable to attend the forum, no worry, we have many letf, for both the simple starter kit (two leds version) or the RGB leds version for advanced users.

A lot of pictures were taken during the event, you’ll be able to see the interest for our introductory workshop:

Technical Data

The starter kit is both a soldering introduction kit and an ARM Cortex-M0 micro-controller discovery kit.

Technical Data to be updated.

Reference manual yet to be written.

Schematics sources (KiCad) and other usefull technical data (documentations and BOM).

Source code not yet available. Best choice is mbed for LPC812 target.

Uploading a new binary requires an USB-UART adapter.

Starter Kit


The “Starter Kit” has been created upon a request from Open World Forum organisation team for a soldering introduction workshop during the “Experipent” day (Saturday).

Rather than creating a limited, almost useless assembly that would blink a led, but no more, how-ever hard you try, we set a somewhat more ambitious target: creating an ARM micro-controller dev board within the budget (which would blink a few leds … of course).


No problem, NXP just released a brand new micro-controller in DIP8 package (big one, easy to solder): the LPC810. Despite it’s clumsy appearance, it’s an ARM Cortex-M0 micro-controller that runs at 30MHz and has a really big set of peripherals (UARTs, I2C, SPI, comparator, timers, …), and most can be assigned to almost any pin (except the power supply pins …). Other very good point for us : it’s price : about 50 cents (0.5 euros) (when you buy 1000).

Our “Starter Kit” is much more than a simple blinking led badge. After improving your soldering skills, you will be able to discover ARM Cortex-M0 micro-controller programming, change the led blinking scheme (or the RGB led color for the “expert” version), or do much more with some of the powerfull micro-controller peripherals.

Of course this is an “Open Hardware” design, so you’ll find all the sources on the technical data page.


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 !

A preview of the PCB for your own eyes only:


Next part of the GPIO Demo Making Of

Open Silicium

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.

GPIO Demo module documentation

The first release of the GPIO Demo module reference manual is ready !

You can get it here.

This reference manual includes all technical information about the hardware (mechanical data and electronic schematics), some help about the software, and a step by step guide for DIY module assembly (which you can buy either as a kit or monted in our online store).


Participation to 2013 edition of the “Trophées PME bougeons nous”

We sent our application for the 2013 edition of the “trophées PME Bougeons proposed by RMC in order to spread the word around the DomoTab project.
We should participate in the preselection in lyon on September 6th 2013. We’ll keep you posted in the incomming weeks about the results of these.

Anyway, we can only congratulate both the initiative renewed for the fourth time this year and the simplicity of the registration process, which does not require a month of full-time work but only a few minutes on the Internet !

EDIT: OK, application form was simple … but we got nothing more than the confirmation email.
Despite all our email sent to get in touch with them we got no answer. Preselections are running, for Lyon it was last Friday (September 6th 2013) ….

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.

Laser cutting, once again !

After our laser cut CMS stencils, this afternoon we ran tests to get masks to cover the holes from unused module slots in the DTPlug boxes or cover the space around the module connectors.

The tests took place on local FabLab (fabrique d’objets libres) laser cutting machine.
