The avi didn't work for me. 4 sec of blackness.

Chris,

Here you are a flash version (sorry Mateo - I cropped it a little bit for it wouldn't have fit here)

Gaieus, what did you use to convert to flash?

Chris,

There is this "Giveaway of the day" website and I have found really nice little apps there. This was "Wondershare Video to Flash Encoder" and was free to download some time in Summer.

And just now, as I chacked back to get the link, I saw that I have just missed "Wondershare DemoCreator".

Well, these are some 20-30 dollar little programs though (and would mostly be useless for me) but sometimes you just find something useful.

This one can only convert avi files though (I don't understand why cannot it use raw mpg's for instance)

Gaieus,
Thanks for the information. That will come handy.

Hey guys,

I've just found another software (now for free), see the post in the "Hardware, Freeware & Gadgets" subforum here: http://www.sketchucation.com/forums/scf/viewtopic.php?p=12749#p12749

Hope it will be some use.

Thanks Csaba.
Is this the kind of program used to make video tutorials and presentaions?

Gidon,
Yes it is, but as You can see I had also made a
recording of Your Ornithopter flight with it.

I also downloaded Wink which I believe Coen uses for his online Flash tuts here. Actually, there are quite many good (and even some free) applications that one can sometimes hardly choose.

I'll test this latter one out (haven't installed yet) and see what it knows for 300 bucks that other freewares do not.

But now let's go back to "on-topic" and talk about Gidon's ornithopter!

OK, here's an update.
I built a very rough version of the drive mechanism and found that because the configuration utilises the pulling power of the rubber band rather than twisting the rubber band it was much more powerfull. Much more. This of course means that this configuration, while not being any larger than the twist configuration, can flap much larger wings and in a larger motion. It also means that I can make the body longer to accomodate more stretching of the band because the larger wings would have more lifting power.
At least, that's the theory

Gaieus

So whereis that update?
