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 :)

Mini Maker Faire Lyon

Techno-Innov will be present for the Mini Maker Faire Lyon on Mai 28 and 29.

We will hold a soldering workshop for those looking forward to learn or improve their skills, or want to discover new soldering tricks and make professional quality PCB at home at very little cost.

You will also discover our latest boards, assembled this week :)

Techno-Innov’s Car-System

The presentation pages for our Car-System are now online.

This Car-System has been developed during the last two years for Mini World Lyon model exhibition project.


There are many improvements yet to develop, but development is frozen until the opening in June 2016.

To get to the presentation page, follow this link !

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.

Technical Documentation for the RF-Sub1GHz module, USB version

As we said, the effects of the new start of the DomoTab project are here, with the technical page for the RF Sub-1GHz module being online and the User manual for the USB version of the RF Sub-1GHz module also ready for download..

UEXT and Standalone versions of the module or very similar to the USB version, so the documentation for these versions should be ready soon.

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).
