    Neat, I can't tell how you're keeping the wires from shorting. I mean the parrallel green pairs are live right? Are they insulated except for at the LED?

    the white fabric acts as an insulator. the parallel green stitches are regular thread, conductive thread is the bobbin (bottom) thread for these stitches & is underneath the fabric. the grey patches at the LEDs make contact w/ these column threads on the back of the fabric.

    Sweet! Why do you have two horizontal traces per row, though?

    "smd soldering on machine embroidered circuit"

    So - did you solder the SMD LEDs directly to the embroidery?

    hi muffinator! no particular reason for 2 horizontal traces... you really only need 1.

    yey !

    now the litlle led dot should move according to the deformation of the textile ;)

    cheers,

    This is excellent, now you need to combine it with Evil Mad Scientist Laboratories' Peggy 2.0. If you are unfamiliar, it is an open source hardware project, (up to) 25X25 LED controller, that can even handle sprite animations.

    Yeeter,
    Leah's circuit already has the same architecture and capability as the Peggy 2.0; her fabric circuit here is BAD-ASS, and I'm sure she'll find some fantastic things to do with it. :)

    Amazing (simple) technique to create a display that fully deserves the 'textile display' label. I wonder what kind/type of conductive yarn is used to allow direct soldering of components?

    If 8 LED are light ON at the same time (one line), What is the maximum power of an LED, to be sure to no burn the Lily?

    Hmm I wonder if you could combine these with capacitors to have them light up based proximity to ground or some such.

    ground in the electrical sense... :)

    hi where can i buy the silver thread?

  13. leahbuechley 70 months ago | reply

    I'm soldering to metal wrapped yarn, but also using silver plated yarns. the silver plated yarns you can get from sparkfun: www.sparkfun.com/commerce/product_info.php?products_id=8549

    as for maximum power xy/md, I've never burned out a lily, it'll just max out at 40mA, so if you turn on lots of lights at once they'll be dimmer than one light would... coming to boston to visit sometime? cheers!
