Nice work! The second video (the one you posted here in the comments) is much clearer than the one on your project site, and the animation came out much better.

A very cool project indeed.

I just got done reading through the details of your build, and find it even funnier that we used the exact same RGB LEDs and uC. :)

I need to update the info on our website (hope to do so this weekend), but we actually did a very similar project for our Sr. Design course…Only we passed up on the wireless in favor of doing multiple layers for a 3D effect.

a short demo is up on youtube, more coming later:

The current version moves the wave faster and with less visibility between the layers…it also displays (rough) 3D maps.

Funny that two groups on opposite sides of the country were working on the same thing at the same time :)

hope that choppiness in display is just an issue with fps in camera

We already did parts of that. Through the gui, you can load 63×63 bit images in cartesian. A java program that was written then converts it to polar coordinates and displays the image on the propeller clock. That’s how all the 1, 2, 3, and the smiley are generated on the display. Of course, we are interested in updating our program so that we can somehow do that on the fly and maybe make all the numbers on the clock point in a “upright” direction dynamically and not through rom (which can be done through that program I mentioned in the beginning). A future study would also to do this in a 3D version or in games as well. You can see this cartesian to poloar generation better here: http://instruct1.cit.cornell.edu/courses/ee476/FinalProjects/s2009/ht227/POV1.MP4 The left side of the GUI (when house is displayed) is the picture in polar coordinate. The right side is it in cartesian.

Nevermind. I should have watched the video before I spoke.

I would love to see another layer of abstraction that lets you push data in Cartesian coordinates to allow images and text that can be orthogonal and right-side-up, so to speak.

An example of this can be seen here:

Quote from description: “Wet Noodle: The ultimate wire for full race applications. 12 Gauge silicone wire with an unbelievable 1660 strands, it is so flexible that it feels like a wet noodle!” I don’t know if ours had 1660 strands, but with wire that thin, it feels really soft.

“wet noodle” brush? Is that slang for something else, or was there pasta involved?

Nice hack.
