[Craig Bellaire]

OK I fixed the PDF... hope this helps...

Just wondered also what GG are you using.

I've got some 1500 grit GG from thorolabs and might try and vibrate it...



Thanks

Are both links supposed to be the same? I downloaded the first one and it incorrectly describes the adapter as an XL EF adapter but the second, fixed link seems to be a copy of the first only it doesnt work because it has the ellipsis copied as well.

edit: nevermind its fine now

[Craig Bellaire]

Yes both should be the same..Meaning with a corrected version "non XL EF adapter" I did double check both links and even edited the message just to see if something messed up.. But from my machine both are working fine...

Craig,

The PDF file looks good. I used the old link to download the new one. This PDF file will be better if we add the link to those emachineshop files. I just uploaded the new version of the Front.ems. There will be 4 files:

Thanks.

Quyen, you are a scholar and a gentleman! This is definitely above and beyond the indy spirit

Thanks. I do share most of the info but will keep some essential info on the commercial unit that I will be selling. Sorry, it's business. Hope you all can get enough info to make and enjoy the adapter, thanks.

There are 2 more steps to complete the design.

1. Use the 4th custom made part (insert1.ems) and snap the surplusshed condenser in then place the flat surface against the GG. Make sure you space it out a little bit so the GG plane can move freely, then drill and use screws to secure it in place.

2. Use UV filter or clear glass cut to the size of the Front part and use glue to hold it in place so the unit can be dust / dirt free. Buy some kind of mount or take out from the old/broken camera to mount on the other side of the Front part to mount the lens.

Use air hose to blow away any dust inside the aluminum case, GG, Condensers ... and close the case, you now get a light, compact, professional looking yet low cost Depth Of Field adapter. Hope you can enjoy it as much as I do.

I have more than one design. This one is the best and if it's done correctly, it will have circular movement when the pager motor is on. Precision? not quite. This design doesn't require tight spec so it can be done with drill press (that's what I use). The most important thing that you keep the drill size the same as instructed, don't change the drill size the way you think to make it work better, it won't. If you don't have the correct drill size, go and buy one, don't settle for anything other than the best.

Use lightweight material for GG plane. Don't use metal, use some kind of light weight plastic.

For people thinking that you can get something else to replace the syringe parts, I would like to hear from you when you get it working. I wish you luck too. I hope my design will inspire some people of making better / cheaper adapter that people can use without hurting their pocket.

I have been working on this design for months. It's not the luck that I get it to work, no luck here. I have done a lot of research and spend a lot of money in this design. I will get it back eventually. I admire Dan and other for their hard works and sharing the info. Without them, this design can never be done. Thanks.

If making custom made parts is hard for you, I offer to sell 4 custom parts with no drilling for $65 shipped to you, I currently have FD and Nikon mount. If you use different lens' mount, let me know, I will make a mold for it.

Thank your for sharing the great resource, simply awsome!
You're making me completely into the vibration path!

Question about the vibration motor again
Have you ever done endurance test? Like switching on the adapter (motor vibration on) for an hour or two continuously? Or even 10 hour continuous?

Durability of the Vib Motor is my concern. Some people told me 'no problem' and the others saying 'tricky', so I'm a bit confused.

If this durability issue is cleared, I would definitely give it a try after my editing jog is done.

cheers

I have done some test but not that long. I think one or two hours a day, the motor can last for years. We suggest using 1.25v rechargable battery. We even tried with 3 volt and it runs fine. The motor is made for vibrating purpose and create very little noise, I think it doesn't wear very much. In this case, it carries no load at all except the off set weight. I have heard some people use this kind of motor to make stuffs and they even use gear and shaft. I don't know for sure how long it will last and how stable it is, just try and know. Beside that, my design is really easy to change the motor if it's bad, just 2 screws and it's up and running again. I have use this motor and convinced that it will last. If you are not sure, buy more than 1. 10 of them may cost $30 or less, so it's not a big problem that you have to think so hard.

Please give me some feedback about how this design benefit you or any suggestion to change in the design, it would help the people in this forum further. Thank you for all your opinions.

If this design benefits you, I ask you for a return favor. Tell others about this design so it can benefit them as well. Support me financially by buying my products would be very helpful for the community because I will have more money doing research and at his point you know that I do share. Thank you all very much and I enjoy doing this for you.

Quiyen,
What is a '.ems' file?
Thanks,
Valeriu

[Quyen Le]

.ems file is emachineshop.com file. Download the software and view the files. It has 3D option and it's really cool. You can view the part like you are holding it on your hand, hope this help, thanks.

Thank you!
Just looked at older posts and found it. Great Job!

great work and i am interested i your device.

a couple of questions.

1. Is the image still inverted?

2. What can i get away with lens wise. I am trying to make something dirt cheap. I have a nikkor 1.8 50mm lens, which was like 38 bux. can i shoot a whole film on 50mm?

can i get another lens this fast this cheap and where? Otherwise its gonna cost em a grand just for lenses.

great work on this adapter IMO.

Thank you for interested in this device. I will try to answer your questions to the best of my knowledge.

1. Yes, the image still inverted. We don't want to sacrify quality. You can get image correction by buying external LCD or any other method that suggested on this forum.

2. The purpose of this adapter is to get shallow depth of field. Other than that, you can use prime lens that come with your camera. Fast lens can give better result but this adapter will work with virtually any lens. I suggest you go and search for Canon FD lens 50mm 1.4 on ebay. Saw one today at $40, very good price.

Hope this helps, thanks.
