back to article LOHAN's vital statistics splashed across fruity display

Our Low Orbit Helium Assisted Navigator (LOHAN) mission has just been served an extra slice of Raspberry Pi in the form of an all-singing, all-dancing balloon chase system. Hydrogen helium head honcho and electronics wrangler Dave Akerman decided haring around the countryside in pursuit of mighty orbs would be a whole lot …

    I dunno, you add any more processing power to the thing it's going to become self-aware.

    All it needs now though is another Pi especially programmed to take evasive action when confronted with trees, hillsides, pylons and other such attractants. Or at least to get itself down from them without intervention of meatsack and ladder.

    Looks a nice bit of kit though - obligatory beer to be raised and suitable acronym name competition to follow I presume?

    Pi powered planes, and you're using technology created by a man called Tony Stirk.

    What's not to love?

    I'm sure Dave will turn up to give out the specs, but in the meantime, the code is written for Linux using OpenVG, so uses the HW acceleration of the Raspi for its output. I think he forgoes X completely, so it's a fast, easy to use system.

      Re: OpenVG!

      Yes, all true. Graphics use the OpenVG C library so no X at all. Total CPU for the whole thing (GPS receiver, video streaming, chase car upload, display update) runs at around 10%; without the h/w acceleration it'd be 100%!

    This needs a name.

    May I humbly suggest the "Main Interface between LOHAN and Expedition Yobs"?

      Total Information For Knowledge About Mission?

      Just because.

    about the BRASTRAP

    Can you program it to perform in the event that the mission is going to go in the drink? Well, before the mission would end up in the drink?

      Re: about the BRASTRAP

      We don't need to program it - if the payload's heading towards oblivion, we can abort the mission from the ground.

    This looks so much fun

    So obligatory beer whilst I am stuck in a London office.

    Sorry about the K, it was the best I could manage. Improvements welcome!

      Hmmm, "Kinetics" instead as it's relating to motion?

        Thanks Vulch, that works perfectly!
