Would you pay $30 for DIY vibrating 35mm plans?

What kind of GG and what model of camera. DVX-100??
Click to expand...

The GG is a DIY job. Making the GG is one of the steps in building the Snod35 and covered in detail on the DVD. Camera is a DVX-100B.

As for a full res file. Excellent idea Ed and wjm. Every adapter has its limitations and I am not out to hide anything. Anything specific? I will probably have to keep it under 60 sec. Maybe a short mix of the beach and the garage test?

QUESTION: I recently purchased the following - should be here soon:

1. 58mm +7 Century Optics achromat
2. Canon 500D +2
3. 72mm - 58mm step-down ring

Are these parts used on your adapter? Is your adapter significantly different from Edweirdo's V2 design? Any info would be greatly appreciated. I am particularly interested in the vibrating mechanism - so get cracking on that DVD and stop surfing!

I was originally using the CO +7 and the 500D +2, but wanted to bring the price to build the adapter down since those two together run over $300 (and I wanted to use less glass). The Snod35 now uses redrockmicro's 55mm achromat (72mm for HD cams). I contacted Brian Valente at redrock micro to ensure that there won't be any issues with people ordering the achromats when the DVD is released. He said it would be fine. Redrock's 55mm achromat is only $160 and is the one I was using for the garage test and the beach footage. The nice part is that it comes with a 72-55mm step down and a 55-72mm step up, which drops the cost to build the Snod35 even more. So to answer your question, yes the CO + 7 and the 500d willl work fine, but you might want to consider ebaying them and getting redrock's achromat for $160. I would imagine that you could get $250 to $300 for the other two on ebay or here at DVXuser.

As for this question:
Is your adapter significantly different from Edweirdo's V2 design?

Yes, it is different enough that you will need to buy all of the required parts for the Snod35. Of course, things like lens mounts and 35mm lenses you will be able to use. If you already have a D screen or other Nikon F3 series focusing screen, these can be used for the GG. Keep in mind that we will be grinding the plano side of the plano-convex lens from these focusing screens. The actual focusing plane that comes with these screens will not be used. I have tested the following screens and any of them will work as a required part for the Snod35: D, B, E, K, and R. I'm assuming that all of the F3 screens have the same plano-convex lens as the ones I have tested, but this is something that I am going to double check (on my todo list).

LOL. I hear you. I don't think I've gone to bed before 2am in over two weeks, so the surf trip was a needed break. I'm doing everything I can to get this DVD out there as fast as possible. It of course takes time to do it right. I want people to get the DVD and say "Wow! This is great info", "Wow! That was pretty easy to build", and "Wow! This is a great adapter". :)

hey snod, can you post a few pics of the adapter itself? don't worry, i'm still buying the dvd! :)
Click to expand...

Another good idea, I will get some pics of it up soon.
 
30 sec of outdoor footage and 30 sec of indoor footage would be cool, and whatever best showcases your work, and whenever you have the time, I know you're busy. Thanks!!

I have received many emails and PMs about the DVD. I am doing my best to recover from the wall that I hit when I found out that the motor is no longer made. This was the motor by the way:

http://www.solarbotics.com/

There is a free DVD and parts kits for anyone who can find a pancake motor similar to the one above. If it works as well as the original, I will also build you a Snod35 (minus the achromat :)). Note that it is 14mm in diameter and not 12mm or 10mm. I have many of those and the bar type pager motors laying around already. Keep in mind that the garage test footage and the beach footage were not shot with the original 14mm motor, so don't fret... things are still moving along and we will be building professional DIY adapters with or without the original motor. Having that motor sure would be nice though and would save me from having to make the necessary changes.

Does anybody know Japanese?

if you can give me specifically what you need translated, i can get it for you. living in hawaii there are plenty of people who speak japanese around me, and i can get someone to translate for you.

i wasn't sure which motor you were looking at on the solarbotics page, but if you can tell me which one, i'll see if i can get someone to read the japanese site and see if it's the same.

Yes, I've seen this one. There is no weight on the shaft. One could be added, but I'm trying to keep this as simple as possible for everybody. I think it is a little too powerfull also. Thanks for the post though.

Here is a dirrect link to the same motor at another site.

http://www.hobbyengineering.com/H1207.html

The key is that it is 14mm. The voltage ratings and such at toykoparts look fine for the pancake/disc motors... from what my browser displays. I've sent them a couple of emails, but no response. Maybe the don't have a USA sales rep. The only issue with this, since they are the actual manufacture, is that they would probably require that I order several thousand vs. several hundred.

I am working with another motor today. So far so good. Some vibration can be felt at the DVX mic and viewfinder when the motor is at full speed. At low speed, I don't feel anything at the camera (a touch when the DVX is aimed down). Full speed would only be needed at f/11 and up, so this would probably be fine. From what I understand, the Letus causes a very slight vibe on the cam... and some say that the M2 does as well. So I think this one might work out.

The 14mm would be ideal, so the offer still stands.
 
I tested the vibration pattern of one of the motors yesterday. It did great and made nice little circles. I have another motor on the way that should be the same, but nice ane quiet.

The GG had a few dust specs on it which I left there so that I could see the the motion of the GG. If the dust specs turn into a blurry line when the motor is running, then that means that at higher f/stops the grain will start to show up as a bunch of blurry lines. If the dust specs turn into a blurry "O" shape, then that means that the vibration is making a circular pattern. This is good because each spec of grain makes the "O" shape. This spreads each spec over a wider area and the "O" shapes of each tiny spec overlap. The end result is hidden grain.

Here are some small grabs of the GG with the motor off and then on at f/16.

OFF
GG_dust_moto_off.jpg


ON
GG_dust_moto_high.jpg


If you look very closely, you can see a blurry dark circle that the dust spot is making (just right of dead center). Just shows that the motor is making those nice "O" shapes on the GG.

Here is the test. Please note that the compression hides the fact that the grain pattern started to show up at f/11 - f/16 during the shots that pan across the sky. Moving the camera across a solid and light colored area reveals the grain pattern on my 32" video monitor at these f/stops. Also note that this was done on a GG that has a pretty rough surface (comparable to the D screen). I am testing a GG that has a more fine surface today. I will post how that goes. The brownish color of the horizon is good old fashoned LA smog (blah).

The Test

I know that many of you are anxious to get the DVD. Please know that I am doing everything that I can to get it done (ie: not sleeping :eek: ). The filming of the "building" section of the DVD should flow pretty fast as I have an extensive outline going for each step. Just a few more things to settle with the design, so don't give up on me.

I haven't forgotten about the full res footage and a pic of the actual adapter by the way...
 
That's one too, not twelve by the way. Although I could probably turn around and move the other eleven for a pretty good price. I kid, I kid.
 
Don't sweat it Ed. You're a true pioneer as far as I'm concerned. This kind of reminds me of when the aging mathmetician has to admit that Will Hunting is just plain smarter than he is. And then the nerdy assitant puts his hand on the guy's shoulder and reassures him by telling him that he's still a brilliant man. A little dramatic but that's what it reminds me of.
 
Justin,

The test footage looks great as usual. Good to know you're truckin' along. I check this thread at least 3 times a day. Haha.

Hi Snodart,

I managed to speak with one of the reseller for Tokyoparts in Singapore. They have the 14mm diameter disk motors. But they sell in bulk quantity. I get the feeling it may be in the thousands. But I did say to the guy that I need 50 and he said its ok with him. I have emailed him with the details for 12mm,14mm and 18mm disk motors and see how much they are charging. I can provide you the contact email for the guy in Singapore and you can order from him. Let me check with him first regarding my query or we can do a group order from them if you want. I will keep you posted on this. By the way, great footage from your adaptor.

Alex

Wow. Good stuff Alex. Sounds promising. I would need a few sample motors asap to test. If they work, then I will order 100-200 of them (depending on the price). The motor (no matter which one is used) will be sent out as part of the DVD/selected parts kit. Can you PM me the contact email? If they work, I will be building you a Snod35! Thanks a ton.

More progress today. I just about have the "building of" outline done. Of course that would have to be adjusted slightly if the 14mm motor works out. Easy fix though. I also shot some needed footage for parts of the "DOF explained" chapter. The footage will serve as examples to go along with the diagrams and such. I am starting early tomorrow and will go until the wee hours of the night, so more progress to come.
 
HI Snodart,
let me try to get some answer from him regarding my query. I should be getting a reply next week. If not, I will call him again to find out. Will be expensive for you to do so from the states. I put down an order of roughly 30 pieces. Small quantity if he is ok to sell, I will ask my bro-in-law in Singapore to buy it for me and send them as well. I will send some to you. If all goes well, you can contact him directly. Thanks for the snod35 offer. Is that free? heheee...

Sounds like a plan. Please let me know as soon as you find out anything. Thanks agian. If there is any way that you can get the specs of the motor, that would be outstanding.

Free? I'm sticking to my deal:

If you can get me a 14mm sample, I guess that would mean you "found" one similar to the original Sanko motor. So you would have a free DVD and selected parts kit. If it ends up working as well as the Sanko motor, well then I will be building you a Snod35. Like I noted though, it would have to be without the achromat (I'm pretty tapped from all of the parts I've been buying and testing). I would buy all the other parts, build it, and ship it for free (I hate even ask where I would be shipping it to, but a deal is a deal). That little guy has to live up to the Sanko motor first though.
 
Hi Snodart,

To be honest I didn't realised you had the challenge going on for a snod35 adaptor. I was wondering why you are offering a free adaptor to me. Hmm.. thank you very much. I will double my effort to get the pancake motors for you. hehee..

I believe the manufacturer of the Sanko disk motor isn't Sanko. There are two companies in Taiwan and China that are under the main manufacturer distributor lists. They both have Sanko as part of their company name. Interesting.
