Lots of activity around radio embedded systems (Internet of things)

We all know that Internet of things is going to be the next revolution and it’s on the way, we also know that this revolution will not come from some main existing IT leaders as IBM, Microsoft, Amazon … ( I won’t say Google, because they are good player here) but from a lot of non existent companies/startups. It’s really interesting to see what is happening on crowd founding place like kickstarter (Ok, Amazon is part of it) these days : for sure we can see Internet of things in creation with a lots of connected gadget founded. But you can also found all the raw material used by the future companies to make this revolution real.

A year ago we had a lot of buzz around Raspberry PI ( and it continue to grow even if I think the reality of this environment is under its promise ) which is an interesting platform like BeagleBoard Black coming this month is. In my opinion these platforms are good to do geeky stuff but suffer of two issues : not natively wireless and consuming too much power. I assume Internet of thinks is mostly mobile and wireless : because I won’t put many cables in my house to connect these objects : I want wifi/battery stuff!

Configurer la DMZ sur une BBox Sensation

Un petit article, plus pour le troll qu’autre chose … Depuis que je suis passé à la fibre Bouygues je dévouvre la bbox sensation et son niveau de bug jamais atteind par ce type d’équipement … Aujourd’hui après un reset factory default (seul moyen pour réactivé le Wifi une fois désactivé), j’ai souhaité configuré la DMZ pour ne pas avoir à recommencer la configuration NAT un peu plus longue.

J’avais précédemment rencontré des problèmes que j’avais attribué au fait d’avoir changer l’adresse IP par défaut. Il n’en est en fait rien : la fonctionnalité ne mache simplement pas, tout du moins sur firefox ou safari. Le Javascrit executé ne savant visiblement pas lire le champ prérempli contenant l’IP cible. Ainsi un joli message vous indique que tous les champs ne sont pas rempli et la validation est impossible.

J’en suis donc passé par FireBug : la methode est simple (enfin si l’on veut)

1. Aller sur la page DMZ, se loguer en lançant firefox et activant l’onglet JS

2. Recherche la fonction OnSubmit()

function onSubmit()
{
   if (element('displayIP').style.display == '') { 
      var ip = '';
      writeConfig(false,ip);
   } else { 
      var ip = checkInput(false);
      if (ip)
            writeConfig(true,ip);
   }
}

3. Mettre un point d’arret dessus
4. Exécuter jusqu’à la ligne if(ip)
5. Modifier la variable IP pour lui mettre l’IP cible ex : “192.168.1.253”
6. Continuer l’exécution

Après l’exécution de la fonction, si vous revenez sur l’onglet DMZ, vous verez que celle-ci est activée.

Après, si ca ne marche pas, il ne faut peut etre pas jeter la pierre à Bouygues … ils ont peut etre testé avec IE6, qui sait !

 

 

Idea of the day – Camera companion

After a long period without any idea commit, I propose to imagine a Digital Camera companion, compatible with the main reflex system canon and nikon. This system would be connected to the camera using the USB channel or eventually a dongle type on usb connector, or eventually a wifi memory card system. This is for the camera side. On a tablet side, all the taken photo would be received and transform. The idea is to add GPS location and easily apply filter like in instagram. This can also be use to make panorama automatically or create HDR.

The choice of an USB direct connection could help to automatically configure the camera like for HDR.

As all the idea in this category, feel free to comment, and develop, if you become rich with it … don’t forget to help me paying my house !

PirateBox upgrade to Forban

I’m looking to upgrade my two pirate box to test the mesh network forban between the two. Apparently, this will slow down the device as the TP Link small devices are not so powerful, but i like the idea to be able to create mesh network between piratebox. In my point of view it is the right way to make this project real.

I actually have my two piratebox configured in version 0.5, i’ll firstly update them to the latest version, then add the Forban tool following Matthias’s materials.

I’ll upgrade my TP Link Mr3020 and TP Link MR3040.

Idea of the day – automatic highway payment

The purpose to this idea is to save time at highway toll. Actually if you want to save time (at least in France) you need to have a specific and rented device detecting you and billing you. The current technology could allow the highway company to detect you car registration plate with a camera. This ID could be linked with a registration you have made online of different car you own and a credit card + a phone number.

Car would pass through the toll, be billed and this could be confirmed by an SMS sent to the user.

As a consequence, the system could be faster, not attached with a monthly payment and easier to manage (no hard device to move car to car, return, maintain …)

As all the idea in this category, feel free to comment, and develop, if you become rich with it … don’t forget to help me paying my house !
