Tour de France chalkbot

Bikes Computers & Mobile Fun & Games

I was disappointed to see this chalk-printing trailer, for the riders in the Tour de France, is towed behind a truck, not a bike like it’s predecessor. It looks like it works pretty well, though. The main problem with the original Bikes Against Bush prototype was the huge computer that had to be lugged around with it, but I see here that Nike/Livestrong is using a netbook or similar.

    Is it really necessary to bring politics in to the Make community (e.g. Bikes Against Bush)?

    A full eight months after the last election and you still need to get digs in?

      @Frank – I meant no political sniping, that’s just the name of the original SMS chalk printer project.

    Understood. I no fan of either side, and was a bit harsh in the initial comment.

    Make is my area of imagination and wonderment at what everyone is creating – not what certain people are destroying. Make sense?

    Go ahead and delete both of my comments as they add nothing to the original blog post.

    I must build one! The valve they seem to be using is the SMC VQC2000 series. There must be a pump of some kind somewhere. He talks about “emulsified chalk.” Any idea what this is?
