BEGIN failed--compilation aborted at imageEncode line 12. any clues? thanks!!! When I run the script I get this error message:

There is only one thing that I notice, the rotor isn't clearly noticeable spinning because of the color (white) that is the same as the field coil base and the background while on test disturb a lot to a viewer with refraction. If I may suggest, make the rotor like a color wheel to make it seen rotating. Again, nice job keep it up and continue.. It is a very nice project, very interesting and very educational.

I wonder what would happen if another dimension of spatial information was encoded. Sounds somewhat similar to dolphin language.

If you've a Twitter account I'd be interested in discussing the code and applications for sound to image encryption with you :) (Arrived here via Cracked.com) Thank-you for the post, good sir.

Could this device used to generate larger AC electricity and turn on our household? Thanks in advance for your great commitment in sharing. Best regards, Sutoto This is an excellent idea.

I'll try occulists idea with the fan and its shell cos that will make it so much easier. Can anyone tell me will the magnets from inside of hardrives work?, because they are not cirucular they are oval.. ? thanks rEallay good article and informative comments im going to try doing this ASAP as soon as i can get soem magnets.

It doesn't seems to work, all it gives out is a scrambled mess of frequencies when I watch the resulting WAV on Sound Visualizer. I want to fix it or find what's wrong here, because I think this article is really creative (and I want to use it to obscure some hints in a project I have).

That was why so few are in use today. But some of the attraction for people to construct tube amps today is the sound quality. The differences are subtle in many ways, however there are significant toanl differences between solid state and vacant state when it comes to guitar amps and synthesizers. Overdriving a solid state preamp stage produces a tone quality that is harsh; overdrive a tube preamp and you get an effect people like to duplicate. There is something to be said for an amplifier or a radio for that matter that glows in the dark by it's own internal light and you will rarely find a radio as sensitive as a tube radio with a decent antenna.

One idea to help you visualize that relationship better might be to make a small wind generator using a plastic automobile cooling fan blade as your prop. Use one with the continous ring on the side diameter as it it makes mounting the magnets easy. Then place the coils around the circumferance either behind the blade on a plywood ring cut to a suitable diamter, or around the outside diameter of the plastic blade- keeping that gap as close as possible. The type of RIM plastic that is used in those fans is fiber reinforced so not likely to break or make the neighbors nervous. As a generator, see what your voltages are, and work from there. It is that basic principle that makes your lawn mower run, or charges the battery of a lawn tractor, many motor cycles, snowmobiles, and PWC. And their clearances are often less than .010 inch. You likely would also find many of the books from Lindsay publications of interest as well, particulary the "Le Jay Manual" and "Motor Secrets." http://www.lindsaybks.com Not to mention you wil likely find many other projects ideas in their offernings as well.
