Great Quyen,

1) Did the motor come with the offset weight? How did you add that to it - it doesn't really show in the picture?
2) The piece of plastic that holds the GG - did you make that? I wonder if it would work with balsa wood as well?
3) Did you seal the motor to the base with silicone? hotglue? Does it matter?
4) Are you saying that without the rubber grommets, it did not work - but since you added them, it now vibrates?

Again, that Queyen for your swift replies - I want to build tonight!!

Quyen Le July 30th, 2005 06:49 PM

1. The one I am building use pager motor and has off set weight on it.
2. The plastic piece is done in my shop with plastic injection.
3. Drill the hole that snugly fit, don't need to seal.
4. No, it won't work without the insulin (.5cc) syringe rubber and rubber grommets.

I did some extensive test outdoor, indoor from f1.4 to f16 without any issue, only when I use high shutter speed, then I see grain.

Go to emachineshop.com and download the software then check my files to see the drawings with measurement infos for front, back and GG plane. More to come, Enjoy.

I tested my adapter on the AGEZ1 and there is some vignetting. I notice that the front lens element on the AGEZ1 is small, this could be the cause. I will increase the length of the adapter to see if it help, will post result when it's ready, thanks.

Quyen Le July 31st, 2005 11:36 AM

Tried again today with the same setup and different condenser.No vignetting with AGEZ1, thanks.

Quyen,
Great work so far man, keep it coming.

I think the emachineshop.com software was a great idea and is an excellent way of sharing your design with everyone. Makes it so clear to understand.

We want more!

Cheers,
Wayne.

Leo Mandy July 31st, 2005 02:45 PM

That looks great, thanks for the emachine link Wayne, I would have never known. Mine is coming along fine right now, but I can't find a source of syringes at present, tried home depot and a few dollar stores, but nothing. I am trying to source close before I do the online ordering route.
All I need to do now is set up the focal length and place it in a square container.

Greg Bates July 31st, 2005 03:35 PM

Drug store pharmacy, just go up to the counter and ask for them. In most cases you do not need a prescription, just the size. Quyen Le thanks for sharing this info, it is enourmously helpful. What kind of Achromat are you using Quyen?

Quyen Le July 31st, 2005 06:42 PM

I use the 58mm macro lens sold on ebay and 1 of the item from surplusshed.com http://www.surplusshed.com/pages/item/l3385.html .

I am going to take all measurements and part lists in the next couple of days since I still want to make the unit dust proof.

If anybody is interested in a kit, let me know. The kit will include all the custom made parts and all the necessary parts and instructions to make the complete adapter. If you think you don't have the skill and necessary equipment to build it, I can build and send it to you. Thanks.

Quyen

Bill Porter July 31st, 2005 08:59 PM

Quyen,

Great job and very nice of you to share so much info. Even though I'm not building one of these at the moment I enjoy seeing new posts on this thread every day.

Thanks!

Quyen Le August 1st, 2005 11:13 AM

at surplus there was a better lens dia 52mm and achromat for 5$ each.
they even getnow 68 and 78mm dia achromat (for pana DVX100 and hdv sony)

Leo Mandy August 1st, 2005 11:44 AM

Yes Quyen, I am loving the new thread on vibrating mechanism. Keep it up, I am looking forward to the new design.
Which way do you have your surplusshed macro facing?
1. (| Camera
2. |) Camera

Giroud Francois, do you have a link for this? I couldn't find the one you were looking at specifically...

Noah Yuan-Vogel August 1st, 2005 11:47 AM

I love watching test footage, is that weird? A few questions though:

Were some of the shots done without the motor on? There is some static dirt on the GG for a few shots. Also it is a bit difficult to tell about sharpness since the video seems to have weird persistent interlacing artifacts and seems a bit soft. What camera did you use? Any chance of getting high res stills from the dv camera or from a still camera of the images through the adapter? It would be great to see how sharp the image is at high resolutions to see if the system is alright for HD.

Quyen Le August 1st, 2005 11:51 AM

I forgot to clean it before shooting this morning. There were some spots there. I will try to capture still image, just don't have the memory for still. The camera I used was vx2000. I don't know why the video is interlacing.

I use Camera [) then surplsshed (]GG Lens.

Quyen

Leo Mandy August 1st, 2005 11:53 AM

I am not sure which post you are responding too Quyen, mine or Noah?

Quyen Le August 1st, 2005 12:09 PM

Mandy,

Just edited my post.

Noah.

I will find the way to take high res still pictures

Quyen

Leo Mandy August 1st, 2005 12:35 PM

I wish I could take back my macro lens - Tiffen's that have such colour abberation and separation that it is unusable! I hope your macro lens is better than mine!

Quyen Le August 1st, 2005 01:23 PM

Still image
 
http://www.nuocsong.com/nhatho/adapter/sharpness.JPG

The above picture was captured using handheld digital camera. Because of light reflection, the rest of the image was bad, I can only crop out about 1/4 the size of the focusing screen which is about 1/16 of the image size of digital camera's image. I think the focus is sharp, don't you think? Thanks.

Quyen

Giroud Francois August 1st, 2005 03:49 PM

at surplussched you need to look in category ACHROMAT not into LENSES.

Quyen Le August 1st, 2005 05:10 PM

Light Loss
 
Did some test today and it shows my adapter lose about 1 stop of light using Canon FD f1.4. That means the adapter itself will lose about half stop of light.

Quyen

Greg Bates August 1st, 2005 05:45 PM

Where do the syringes come into play?

Quyen Le August 1st, 2005 05:49 PM

I will try to build one and take pictures with instruction today. The syringe parts was hidden in the new version, did not show in the pictures.

Quyen

Leo Mandy August 1st, 2005 06:16 PM

Quyen,

Instructions would be great, love to check it out against the one I am building!

Quyen Le August 2nd, 2005 04:14 AM

Below are pictures with instructions. I assume you downloaded the emachineshop.com software and view the 3 custom parts that I posted ealier.

Wayne Kinney August 2nd, 2005 04:36 AM

Quyen,
Excellent work my friend. I think I speak for everyone when I say I really appreciate your hard work and time to share you design with these detailed instructions.

Perhaps we should all get together and source out online suppliers for the parts needed? Im in the UK and found suppliers of syringes and pager motors on ebay.

This is really coming along, keep it up.

Wayne.

Scott Grocott August 2nd, 2005 08:22 AM

Quyen,

WOW. Excellent tutorial. You are very resourceful.

Thank you very much.

Quyen Le August 2nd, 2005 10:47 AM

Thank you.

Making the guide is harder than making the adapter :)
There are a lot of parts out there thought to be better to use but I have reached the limit of my expense. I have spent well over $1000 for this project already. My intention is to make affordable commercial units. I have an challenge on this forum of making this product for $150 when I introduced my cup35 design, well, with better design and all the good stuff that add on to the unit, I think this unit worth more than $200, don't you think? I know that there are some of you enjoy making the adapter so much and you won't buy the adapter at any price, but there are still a lot of people don't want to get a hand on it but to get the professional looking video. Here is my offer, for the limitted of time, I will make this adapter for only $200. With all the measurements, calculations, I can only make 1 unit in 1-2 days. Macro lens/ condensers will be included in this adapter. I designed this one base on my vx2000 with 58mm filter size. If you want to use bigger or smaller filter size, you have to get the step up or step down ring yourself. I am working on an 72mm version now and will post it when it's ready. Thanks.

Quyen

Leo Mandy August 2nd, 2005 10:50 AM

Quyen,

Those machined parts are awesome - do you manufacture rubber and plastic as your business from your home? Having the ability to do that is great!

Darnit, I can't find those grommet and syringes anywhere - Walmart has syringes, but they are not the right kind and Home Depot and the $1 store didn't have any - any ideas?

I am using a small toy motor that seems to give me pretty good results, but Quyen is right, you need the rubber to get proper vibrations. Also the aluminum case is a great idea because of the heaviness to stop the vibrations.

Quyen Le August 2nd, 2005 11:10 AM

The grommets, I bought at the local surplus store. The syringe parts, I got from my dad. Find some diabetic friend and ask them to save you some. I believe you know some people with diabetic.

I built my hobby plastic injection and all my molds at home here. I also have FD mount XL1 adapters, EF mount XL1 adapters, AI mount XL1 adapters and FD mount adapter for Canon L1 L2. All of them made right here at my shop. If I have to order those parts, I can noway to offer the $200 price for this adapter. I hope you enjoy my pictures and guide, thanks

Quyen

Steve Brady August 2nd, 2005 12:16 PM

Quyen,

So for $200, you'll sell me a box that I can screw onto the front of a GL2, attach a 35mm lens to the front and start shooting? How would you like me to pay?

Quyen Le August 2nd, 2005 12:17 PM

Paypal me quyentle@hotmail.com, thanks.

Quyen

Noah Yuan-Vogel August 2nd, 2005 12:21 PM

Now is it the rubber syringe part or the rubber grommets that allow movement? if the grommets are necessary for allowing more movement, would it be possible to use something less rigid than the syringe part to allow for more movement and then not have to use the grommets?

I just was thinking the adapter would be easier to make if it used the lowest possible power and size motor (maybe 1.5V for fewer cells?) and did not require grommets which seem possibly difficult to get since i imagine the rest of it could be made with a drill a small saw and some pvc/wood for those of us without injection molding plastic capabilities.

Also, I kind of liked the bead design in that the beads were quite short, an adapter with less depth might allow for interchangeable lens mounts (which i think could be very useful). Maybe even use a larger GG with interchangable mounts so people have the option of using larger format lenses for tons of shallow DOF. Your design has the lens mount built in, right?

Also, I imagine for those of us that have camcorders with removable lenses (canon XLs, homemade HD, etc) it would be easy to use extensions to increase the macro abilities of a lens rather than using macro +10s or +5s that have a lot of chromatic abberations and such. (maybe thats a topic for another thread)

I think your guide is really awesome, probably the first and only oscillating design I've ever seen with really good and simple directions that are freely available. I know its a lot of work to document such a process so everyone can have access to it and understand it, so I really appreciated the work youve done.

Leo Mandy August 2nd, 2005 12:26 PM

Injection molding? Sounds cool, where can I buy a device like that? Are they expensive kits?

Quyen Le August 2nd, 2005 12:43 PM

Hi Mandy,

Hobby Plastic injection alone is not enough without the mold. I have built several of those so far, not really hard at all. I think this thread is for 35mm Adapter, email me and we can discuss more about it, thanks.

Quyen

Quyen Le August 2nd, 2005 01:10 PM

Hi Noah,

There would be movements on both the base (front part) and the GG plane. Just thinking of a table, when the legs are loose, it will move, when the legs are tight, it won't move at all even if it didn't attach to the floor. Same as this design. Both planes need to allow some movements for the GG plane to move freely and don't send back to the camera that much vibration. There is another option to use some flexible thing to replace the white parts of the syringe and grommets. I just don't have luck finding this part. In one of my post have the link to buy those grommets. I never try to order from them yet. I have enough grommets to build 5 units. If I have more order than that, I will think of order more.

The custom made parts, can be done by cutting fence board using miter saw. Drill holes using hole saws ... If you want your unit looks professional, then buy from me. There is a mount built in. I am using FD mount for the one I took pictures. I have 2 mounts available Canon FD and Nikon and can make other mounts if demand is high.

If people here support me by buying my products, then I will have chance to design the supporting rods and have them affordable as the adapter is. I learned from people here and this time is to do good thing for them, thanks.

Quyen

Leo Mandy August 2nd, 2005 01:51 PM

I sent you a private message through dvinfo.net Quyen, but you can email me at mandyyjobs 'AT' yahoo 'D-O-T' com .

I did some scoping out Grommet and syrings today - found the grommets, but not the syringes...

Giroud Francois August 2nd, 2005 01:53 PM

you should sell it as a kit for 98$.
you will sell a lot more when cheaper and you do not bother to build them up.
additionally a lot of people will come with nasty question about diameter of lens or camera or type of lens mount and so on...so it can become very tricky.

5$ for motor
5$ for 3 inches of aluminuim profile
5$ for 4 syringes
5$ for microscope glass
5$ for the plastic rings
20 $ for your injected front and rear parts
5$ for misc. parts
====
45$

you still get 50 for rewarding your work.

Quyen Le August 2nd, 2005 02:02 PM

Leo,

You have to remember that my design is small and fit in the 2.5" square so those small syringe could be right. The size of the syringe is .5cc or 50 units. Hope this helps, thanks.

Giroud

Yes, I did offer the kit for $100 includes all of the Condensers for the first 5 customers. This is very cheap because the custom parts take a lot of time to make. The XL adapter take about the same time to make 1 custom part sold for $124.99 on ebay. There will be 4 to 5 custom parts, not just 3. Thank you for your suggestion.

Quyen
