Glass to Plastic
 
Just wondered how you attached the Glass to the motor. In the Guide you say to use 3 screws... BUT in the picture you seem to have a different attachment Method...

Craig.
Always 3 screws, but with thick rubber washers so the screws will not 'crush' the glass.

Thanks,
Wayne.

What's gyroeffect?

Wayne Kinney September 19th, 2005 06:08 PM

Now this is a hard one to explain:D

Its a force that acts on a spinning object. With my spinning glass, there is a resistance to any rotational movement around its own axis, but only around 2 axis, the other two axis other then the one the glass is spinning around

Im not very clear about it, but see here for a more detailed explaination.

Or if your a mathmatician, go here;)

Ok, but How does it affect performance or use in the real world?

Michael Maier September 19th, 2005 06:20 PM

How loud is the adapter by the way?

Wayne Kinney September 19th, 2005 06:21 PM

OK,
Basically there is a theoretical resistance against panning and tilting movement. Have I noticed any resistance when using the unit? NONE AT ALL.

My only real concern when first coming up with the design a while back was if the gyroeffect was going to be so strong as to shatter the glass. I now know that this is not the case with my design.

I think the main difference was the macro with the tests with the dvx100? Not sure.

I have a potential buyer wanted to use onto a dvx100a. He would post results with my unit. I dont have access to that kind of equipment, sorry.

Thanks.
Also, I wonder if the results wouldn't be worse with a higher resolution camera like a DVX100 and XL2. I think that happened to the Letus35 is another thread. Somebody said it looked better with a cheaper camera than with a DVX100. Do you have the possibility of testing it with a better camera?
