Homemade 35mm Adapter

Danny Tan · December 14th, 2003, 03:27 PM

ok i get it now. so the wide angle macro lense with the detachable wide angle lense will work then right?

Stewart McDonald · December 14th, 2003, 03:32 PM

Any cheap macro filters for the gl2?

Danny Tan · December 14th, 2003, 03:41 PM

yea probably. agus used a magnifying glass in his original one i think

Imran Zaidi · December 14th, 2003, 09:01 PM

The gl2 shouldn't need a macro lens at all. It can focus on things all the way up to the lens itself.

Danny Tan · December 14th, 2003, 09:57 PM

ok so can some1 confirm that the GL1/GL2 doesn't need the macro lense? i dont wanna waste $40

Jon Yurek · December 14th, 2003, 10:13 PM

At the risk of repeating information in the same thread, the GL1/2 can only focus in macro mode when completely zoomed out, which means the projected image will definitely not be filling the frame.

So yes, it can focus that close, but not in any way useful to what you're doing here. It will still need the lens.

I call it the Agus35 Mark III.

http://www.sillydaddy.com/Agus35_MarkIII.html

I Haven't shot any video with it yet, I need to close the sides and build a way to mount it to my video camera and maybe paint it.

I'm thinking a bellows would look really cool and make it look like a professional piece of equipment.

Also a cover over the motor and battery would help make it look nicer.

A few of notes,

I used the bolts so I could adjust the distance from the lens to the GG. The double nuts are tightend agains each other but not tight toward the front. This lets the bolt spin.

I used Blind Nuts/T-Nuts on the back. I cut the barbs off and smoothed them down. I then put them through the back and used some hot glue to hold them.

Once I got the distance right, I put nuts on the part of the bolts that protruded from the back and tightened them to hold it all in place.

The cost so far....

$1.50 for the 1/8" hardboard
$3.00 for the bolts, nuts and washers
$0 for the CD motor and spindle, The player was broken ($12.00 for a new player)
$0 for the GG, It was lying around in an empty CD spindle.
$2.50 for Battery Holder

If using a GL2 I think a macro lens or fresnel lens will necessary because I put my frosted cd right up to the lens, and it doesn't completley fill it as you can either see the center piece of the cd or the outer edge. Anyone got any links to a macro filter for the GL2 please?

How about these?

Agus,

Two questions: How did you attach your GG to the spindle? That's an awfully large hole to close... How did you keep it perfectly parallel to the lenses?

I'm redesigning mine. Pics up shortly.

I've just dismantled an old cd player and taken out the motor, but my queston is where do i put the wires??? i cant seem to get it to run

J. Clayton Stansberry · December 15th, 2003, 06:05 PM

Noah,

Cut the positive and negative wires leading to the motor (red and black) and make sure you leave the wires long enough. Then, you need to connect them to a switch or directly to a battery pack (both can be purchased at Radio Shack). The battery pack will also have red and black wires, connect those together. For the switch, connect the two red wires to the switch, then the black ones together (I think). They also have a switch that allows for connecting the negatives to it. Hope that explains it.

Almost got the full package now. Got some fresnel lenses this morning. Can't wait to give this bad boy a try.

Anyone know if its safe to run a CD motor from a 9v battery?

And is the fresnel lens purpose to increase the image size that is projected onto the cd?

Thanks

Peter Sciretta · December 16th, 2003, 06:45 AM

the cd motor runs to fast in my opinion with 2 AAA batteries which is like 3 volts... so to answer your question on the 9 volt battery, its a negative. 1 triple A would probably the best case but not the easiest to pull off... 2 AAA is probably worth settling for

Stewart McDonald · December 16th, 2003, 06:46 AM

Thanks.
I'm still having a problem finding a macro adapter that will work with the GL2. Been looking all morning with no luck.

Any recommend any?

Ok, here are some new pics of the adapter. http://altoque.tv/35mmAdapter/adapter01.jpg http://altoque.tv/35mmAdapter/adapter02.jpg http://altoque.tv/35mmAdapter/adapter03.jpg http://altoque.tv/35mmAdapter/adapter04.jpg http://altoque.tv/35mmAdapter/adapter05.jpg http://altoque.tv/35mmAdapter/adapter06.jpg http://altoque.tv/35mmAdapter/adapter07.jpg http://altoque.tv/35mmAdapter/adapter08.jpg http://altoque.tv/35mmAdapter/adapter09.jpg http://altoque.tv/35mmAdapter/adapter13.jpg BTW... tom, let me tell you that you need to close that box, or the outside light will ruin the image, you need to make a camera obscura, and all the GG have to be covered... (no peeking !)
