Cellphone-controlled home

[Tixlegeek] used a Motorola 68HC705J1 development board to remotely control his home through his cellphone. The video above, as well as [Tixlegeek]‘s website, is in French, though the video has been captioned. The development board (called the ERMES125) is controlled by a PIC externally. It has an array of LEDs, and apperantly a few high voltage relays. The PIC is connected to a laptop through a serial interface. The laptop is running a small web server, which uses CGI to control the PIC from a webpage. This system allows [Tixlegeek] to log onto the webpage from his web enabled phone, click a few buttons, and have appliances turn on or off through relays controlled by the PIC (via serial signals from the laptop).

    Nice job of pulling it all together into a useful system. I prefer to have both feedback sensors and a watchdog circuit on any remotely activated, mains powered project, though.

    Using UL rated COTS equipment helps with that.

    Wouldn’t that be awesome to be sitting at home and all of a sudden your house starts going haywire cause some script kiddie broke into your house’s webpage. Pretty cool project though.

    I guess that could pose an issue, but [Tixlegeek] seems smart enough to implement a decent security system on the page.

    The relays, and the required wiring to the devices seem like the Achilles heel of the hack. An X10 interface to the same development board would be cool. I wonder if anyone has tried that.

  5. Scott: Forget x10, its crap, everyone is abandoning it, Insteon is better but still has same issues that plague X10, move to ZigBee or anything else for that matter. It wouldn’t be as bad if the manufacturers would stop trying to save 20 cents on a proper band filter.

    Had the home automation working via WAP browser on the non-smart phones back in 2000. Simpler with the X10 activehome kit (comes with pc interface). Linux drivers are available. No separate controller board needed.

    Thanks to publish it, and for the Hackaday’s STaff, i’ve given very less information than us!

    So, i’ve try to translate my Blog page for the English-speaking hackers ;)

    Tater, and Jacob Woj, yep! i’ve written a little “security patch” n___n..

    If i find any hackable wireless system in wastes, I’ll use it in the next level !

    Hey Tix t’es connu maintenant c’est sur t’as pas fait un travail de kikoolol ils se devaient de faire un article sur ton travail, bravo!

    Hey Tix you’re famous now it’s sure you didn’t do a kikoolol’s job they had to make a article about your work! Congratulations!

    No, this is just that i’ve send it to them, my work is too poor to be really interesting, They have more explained about the project than me in my article.
