    Hi Rob,

     

    I'm trying to utilize a similar mechanism but want it to do a 180 degree rotation between steps. Any ideas on how to accomplish that? On an automaton, I'm trying to make a vertical sign rotate from "for sale" to "sold" every once in a while (a 180 degree rotation).

    Scott, check out the various Flip Face posts, I think they'll cover what you are after. - RI

    How long does it normally take to process an order? I'm curious because I just ordered a copy today.

    To be honest, longer than it should. I've had issues with supply of materials which have caused some delay - sorry! That said, I'm now caught up so the last CDs from the backlog should be shipping out tomorrow and yours in in the batch Tamara. - RI

    Here is a drawing. A tip: The number of oscillations depends on the flexibility and strength of the paper hinge. Good to use is thin origami - paper or tracing paper tear-resistant. The weight (coin) is variable.

    A simple video is uploaded to Flickr this time.

    Thanks for the replies. I've tried to make a video outdoors. Unfortunately, the melted snow and strong wind, the birds would fly away. A little short video to see this once at Flickr.

    A youtube video of your bird pair would be nice. They look beautiful together and the background snow-tree-trunk is also good.

    It has been a pleasure to build this bird model. After a tip from Smelter and umetha I have for the blue bird as a brother an oriole, created. The motion carried by a paper- pendulum rod with weight. They are longer in motion time, but not as elegant as the original. The nod is limited by the width of the box.I have the line pattern with black wings printed on thin yellow paper.

    Nice work Michael! Do you have a diagram of how you changed the pendulum in the yellow bird? - RI

  • PAPER AND PRINTER   1 week 6 days ago
    Paper for printing

    Hi Alessandro,

    I use 180 grams (or a bit thicker: 200) paper when I print automata or models. I have an HP photosmart printer which easily takes that thickness. I don't know if a laserprinter will take 180 grms paper. I guess it's a matter of trying out. Good luck!

    priscope by astromedia

    Astromedia.de have a very posh-looking periscope in black and gold (as well as several telescopes and a microscope), but I'm sure there are simpler ways of making one, e.g. from a milk carton.

    Good luck!

    How much work would it be Rob, to put the pendulum inside the bird?

    You could then loose the linking rod from base.

    Should prove to be quite a balancing act!

    Interesting! I'll give it a try and report back... Meanwhile, I'm hoping to make a model with a pair of birds - love birds for Valentine's day - RI

    Like Jane has done, there is a possibility to add variety of colors and patterns to this model and make a family of birds.
