"Now, i am working really hard now to make a comercial version, which will cost less than 1k, complete with support base, metal rods, and the image will come up perfectly, it wont be necesary to flip it up."

...and when will it be available? Roughly. Hope to see the final result of the clip. :)

Agus... just an amazing thread here... lot's a smart people have joined in, i'm still gathering parts and pieces for my XL1S version but things are looking good, in the meantime, we need an Agus35™ logo to put on our projects-that's to make them official.... Maybe something we can print out and "stencil" on with a spray can or air brush. I done tons of them, so if you need any help feel free to email me at dinor@hotmail.com...

onward!

...and just like that...you are famous!
Wow!!!

I'll take a couple stickers, a black Large shirt, and a membership into the fan club!
Great idea Dino! I'll definitely stencil it on mine (once it's done of course).

Peter Sciretta · December 17th, 2003, 06:37 AM

John - can't wait to see some footage...

Agus - what brand cds did you find the "allready frosted cds" in???? A bunch of people have tried asking you this question a couple times... and you have yet to answer... I have gone through

fujifilm - 30 pack (1gg disc) bought at radio shack

philips - 30 pack (1gg disc) bought at Best Buy, was cheap and came in a 50 spindal case.

Unknown Brand 100 pack $20 at best buy included 4 gg discs

But none have been pre frosted... so what brand are you finding these gems in?

Jon Yurek · December 17th, 2003, 06:47 AM

On the topic of macro lenses, wouldn't something like this work?

http://www.bhphotovideo.com/bnh/controller/home?O=productlist&A=details&Q=&sku=11209&is=REG

It's a 58mm +10 B+W brand macro lens. I don't know if it's really 58mm or if it's a 37mm lens threaded for 58mm, but if it's really a 58mm lens, it'd be quite useful for this, especially since it's +10 like that, you'd be able to have a very thin adapter by having the GG so close to the camera.

Agus

If you're planning on making and selling a pro version of the Agus35, are you still going to release the plans on how to make the amateur version?

Can anyone else post the plans on how it's done? There's lots of photos but it would be nice to have some detailed descriptions of what to do ie how much sanding of the fake cd must be done, how to line up what the 36mm lens sees withe the camcorders lens etc etc

Well done to all the guys who are helping this thread move forward!

Regards

Terry

Peter Sciretta · December 17th, 2003, 07:01 AM

I just sanded a cd with 600 grit paper (I used 300 before on a previous cd) and no matter how much I sand the cd with the 600 grit the image projected is not as good as the 300 grit... what am i doing wrong?

Terry Wright · December 17th, 2003, 07:40 AM

Hi Guys

I've just been to a glaziers and asked about having the fake cd made out of glass and was told that it could be made out of 4mm Satin glass. It will cost about £6 to have it made.

I asked if it could be made about 1-2mm and was told that it wasn't possible to cut glass any shallower than 4mm.

Does anyone know if this type of glass would work?

Regards

Terry

Stewart McDonald · December 17th, 2003, 07:47 AM

I'm thinking that maybe the glass would be too heavy for a cd motor. If you have a more powerful motor however it might work

Bob Hart · December 17th, 2003, 08:32 AM

To: Terry Wright. I don't think your satin glass is going to work. First up you've got a balance problem, then there's the power issue as mentioned in another response. The satin glass that I know also transmits too much light, is not finely opaque enough to adequately work as a projection screen as fine ground glass or etched glass would.

To: Everyone. Here's one slightly out of what you US folks call left field. Some years ago I thought I would do a conscientious thing and clean a rear projection screen on a Teleray motion picture film viewer.What I didn't know was the frosted glas wasn't. Instead it was a fine mist coat of something which cleaned off instantly very nicely.

I ended up using a piece of plastic shop bag stretched tightly over the glass sheet. It had a few wrinckles but did the job.

A piece of shop bag, Mitre 10 Hardware and Officeworks shop bags as used in Australia seem best, more opacity, less variation in thickness.

Pressed between two clear CD disks it seems to display an image without too much flare but still not as good as a ground glass. I arrived at this through ransacking my imagination on how to achieve a uniform coat of wax on the surface of a clear disk then thought of pressing it between two and giving it a few seconds or more in a microwave to melt the wax. Getting rid of the bubbles is a real cow.

Another good opaque material is the motor vehicle registrations stickers were have here, unfortunately in too small a piece. I have not got round to finding the source as I diverged from the project onto something else.

(The original project was to devise an oscillating groundglass for the film plane of any 35mm SLR camera, motor to fit in the space where the film canister goes but then I realised there would have had to have been too much electronic trickery to keep the glass moving in phase with the scanning frame rate of the camcorder and vibration would have been an issue, so I did not go there.)

Matt Gottshalk · December 17th, 2003, 08:53 AM

I've just received my 8x10" ground glass that I purchased on ebay:

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=29981&item=2968796829

Now to find someone who can precision cut it into an 7" circle and drill hole in the middle.

I have to say I think this will work much better than a scratched cd.

Ernest Acosta · December 17th, 2003, 09:38 AM

Hey Agus, sounds like you have perfected the adapter. Can you post some new footage of your masterpiece? Inside and outside with natural light? I have all the materials for the adapter and plan on building one for the Panasonic DVX100. I am just concerned with the size of the ground glass that may be needed for projection. Also a question which hasn't been addressed which is will it work with an anamorphic adapter? Thanks.
