i know agus said somewhere that he has started using a 9volt battery for his mini35...

what are the pros and cons to using higher voltage batteries opposed to lower voltage ones???

Up. - Spins faster enabling higher camcorder shutter speeds - diminishes effect of quality error in groundglass finish.

Down. - Spins faster. - wears out motor faster, more vibation - more noise - battery connection is more prone to failure - hard to fit up in the dark - less common battery.

anybody know of local places you can buy fresnel lenses in dfw? or stores in general? like what aisle would they be on??

James Hurd · January 20th, 2005, 02:22 PM

Cody, what kind of camera do you have?

Cody Dulock · January 20th, 2005, 02:43 PM

well im looking for one for my mini35 since they are supposed to be cheap... im just looking for a cheap alternative to get rid of the "halo" bright spot on the GG.

James Hurd · January 20th, 2005, 02:46 PM

You have a mini35? You don't have a camera? I can help you with the halo...

Cody Dulock · January 20th, 2005, 03:22 PM

sorry, im using a panasonic pv-gs50... little consumer camera with 27mm thread size stepped up to 52mm

James Hurd · January 20th, 2005, 03:29 PM

Cool.

Cody Dulock · January 20th, 2005, 04:32 PM

my mini35 setup currently consists of, project box design with rotating GG. miranda mount for lenses. about 8 miranda lenses to choose from. plus a telephoto lens.

i was having a heck of a time getting the cd closer to the lens so the focus would be correct at infinity. i had my cd motor still mounted to the plastic thing that came out of the cd player...i found out my motor was already sandwiched against the wood i had it mounted to. cut a hole out and its just perfect.

i will post some pictures up when its totally finished. i still have to work on the GG, way to grainy. i have barely even tried though... that was a quick job to see if it works.

After the debacle of my Agus which fell and broke the glass disk and prisms,
I needed a gg fairly quickly and decided to try a DVD+D disk. I have plenty
of failed burns so there's plently of disks. I found you can split them.

Once you get the edge joint started, they come apart fairly easily. One face has traces of the burn or guide tracks on it. This is the face you dress. The
plastic seems to be a better material and is quite tough and takes longer
than the glass to dress in a tumbler. It seems to yield a finer finish for
the same grade of grit than glass but the same problems of variable density
flicker found with the CD-R spacers is still there in certain lighting
conditions. In operation the split DVD+R seems to be thinner and lighter,
spins up and shuts down faster and despite being thin, does not seem to move off the focal plane in pans and tilts as one might expect it would.

When mounting the disk to the hub, do not use contact cement. As this stuff
dries, it shrinks and whilst the disk sits flat when the glue is fresh,
after a while it will tilt one way or another and no longer run true. The
best glue remains the water cleanup white silicone bathroom sealer.

The new images at www.dvinfo.net/media/hart are tests from this disk whilst
it was not spinning, plus the very last image off the glass oharadisk. The
filesnames are "cdstrer2.JPG" "cdstrer3.JPG" and "0038b.JPG"

The optical path remains the same as for the oharadisk in the prism version - SLR lens >> groundglass disk >> 2 x 40mm x 40mm x 56mm x 40mm common thickness rightangle prisms in 90 degree opposition >> 7+ Century Optics Achromatic diopter >> camcorder.
