HOW TO – Make shoes that spell words with light…

PovshoesAbout 3 years ago, I pitched a pair of shoes I made to a “big” shoe company – it used a POV device to spell words as you walk. I think it was a little too out there for the shoe company, but if you ever want to make your own, Dan on Instructables has a great how-to: “The Dance Messenger – Fun persistence of vision toy. Attach it to your shoe and write messages or patterns while you walk, run or dance!” Link.

    I’ve made a setup like this a while back, and noticed
    the screen (TFT) went black for a second when lights
    were activated elsewhere in te house.

    A solution for this problem…
    Still need to dig deeper.

    I suppose you could, but why?
    The characterisitic impedance of RJ45 is 100 Ohms.
    So the single-end impedance to the wire you are using as the return wire is about 50 Ohms (give or take.)
    VGA uses coax which has 75 Ohms single-end impedance to the return wire. So using this as a cheap cable extension is not really what you want to do since the circuitry driving VGA ia expecting a 75 Ohm transmission line terminated to 75 Ohms at the receiver end. Also Coax is sheilded much better than the twisted pair covered by foil in RJ45. The VGA cable is not so much more expensive enough to make this worth it.
