Tuesday hacking evening is tonight to get start with BeagleBone as my RPI is not available for the project I have in mind. So the objective today is to get a LED blinking on BBB board.

PIWan project : Here is a new, quick & dirty project to be done with a raspberry PI : At work we currently have to simulate our application for a worldwide usage. We have really great tools for that but they need expertise and specific campaigns. The purpose of this document is to describe a RPI based solution with two Ethernet cards and some clever command lines to simulate a wan network for developers. The advantage of this solution will be to cost less than 100euros and will be easy to use with the right documentation.
See next pages for implementation details:
The BeagleBone black do not have Real Time Clock and as a consequence each time you reboot, you’re back at time 0. To get it updated to the local hour, you can configure NTP client (if connected to network) using the following commands:
root@beaglebone:~# opkg update root@beaglebone:~# opkg install ntp ntpdate root@beaglebone:~# mv /etc/localtime /etc/localtime.old root@beaglebone:~# ln -s /usr/share/zoneinfo/Europe/Paris /etc/localtime root@beaglebone:~# killall -KILL ntpd root@beaglebone:~# ntpdate pool.ntp.org root@beaglebone:~# /etc/init.d/ntpd start root@beaglebone:~# date Sun Jun 2 17:41:10 CEST 2013
One of the first things to do is to upgrade the Linux embedded in the BeagleBone Black device, The documentation provided for Windows is not exactly clear and complete for Linux, so here is the process à followed :
I just got my BeagleBone black device, this is really looking like a Raspberry PI, but personally I found multiple advantage for this card compare to RPI, the first one is related to the embedded 2GB of flash memory that do not require to add external storage. Thank to that, for the first start, you just need to connect the device to your network and a screen and it run ! After about 30s you are connected to a graphical interface and able to surf the web.
The first issue I got with this device is the micro-hdmi connector located really close to the USB connector, due to the current use of an micro-hdmi 2 hdmi adaptor, i’m not able to connect correctly a USB device.I highly recommend to use a micro-hdmi cable instead of a monoblock micro-hdmi to hdmi adaptor for this reason.
By the way, the device is accessible using ssh (root/rootme) and display can be exported easily.
The next part of the article will be about different comparison between BeagleBone and other systems like Raspberry Pi.

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!
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 !
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 !
