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

What vibrator are you using? It would have to be very quiet and not too powerful. Have you thought of making it with a control switch? I've been messing around with a few parts and taking a few things apart (cell phone, beeper, etc.), just can't seem to find the right one. Nice illustration by the way, Maya don't you love it. Have you tried Renderman yet?

Yep, that's the one. I tried many different motors. The one in the link above is perfect. As far as the control switch... the battery pack has an on off switch for the motor and I also added a 25 rheostat from Radio Shack

This allows you to change the speed of the motor.

Yes, I love Maya. Good fun. No, haven't tried Renderman yet.
 
ASG and Snodart you guys are awesome, but they're out of stock, do you have any other stores that you could recommend?
 
Just google "vibrating disc motor", exactly the same motor is widely available. And when you wire it up use thin flexible wires and glue them to the motor body before you solder it up. Thin wires will interfere with the oscillation less, and the glue will prevent vibration breaking the solder.

I've tried and all I'm getting is the hobby store, PDF files, etc..

Not unless any motor will work, this is what I'm googling


Vibrating Disk Motor - 14mm (0.55") diameter, 3.5mm (0.15") thick



This looks like the same motor in the letus, is it?
 
"Try harder!"



Believe I like to find stuff on my own, but this damn thing I couldn't find. I must of google it 10 times, in 10 different ways. Well anyway thanks!
 
Aye snodart, if you make that guide I may buy it. I still need to see all the foortage of all the adapters that I'm interested in 1st. :D
 
twocik23, you might want to order a couple of them. Their is only a very tiny and thin area to solder the wires to. I had to scrap one motor.

Sounds like a good plan. I came pretty close to buying the M2 or the Letus. I'm glad that I ended up building my own though. I will have some footage on the 31st for you to look at as well.

Well said. I even have something along those lines in my notes for the DVD. It works well to glue the motor in place, then glue the wires in place to the edge of the motor and to the circular piece that holds the GG. Glue the wires so that the ends are touching the tiny leads on the motor... they will be in place and ready to be soldered.

Thanks for looking out snodart, I had a feeling that would be the case!


I can't seem to find any, everyones out of them. Do you have a link, or would you like to sell me a few?
 
I have an XL1S and an HVR in my aresenal that you are welcome to test your adapter out with if you want.

That would be great. Closer would be nice, but we could figure something out. The front thread size on both is 72mm correct?

Update: I found this motor. I ordered some, but haven't tried them yet, so I can't promise that they will work. It looks pretty similar, a bit smaller in diameter and a bit thicker. It has wire leads on it which would be much easier to solder. You can get 10 for the same price of the others that are now out of stock. I have contacted hobbyengineering and solorbotics about the motors to see if they will ever be getting any more in. No word yet.

Also, you can now see the adapter in action. I used it the entire time while shooting our Hero-Fest entry Cache. The only problem noted is that one of the corners moved along the z-axis causing a slight blur in the corner of some of the footage. This is easily fixed by using 3 syringe pistons instead of 2.

I have been working some on the DIY DVD. I will be filming the building of the newest version of the adapter for the DVD this month. We are going to be entering Horror-Fest, so that will be a priority, but the DVD is still on and in the works.

You can watch Cache here:

:grin:
I didn't even notice that. I wish I would have made my user name SnodArt instead of snodart. Looks like "snow dart". I think it is a brand of some snow mobile that keep out ranking my website on google searches. Ah well.
 
Just another update.

We will not be entering Horror Fest, so our primary focus will now be on the Snod35 DIY DVD.

Tim has jumped onboard to help with the various extra topics that will be included on the DVD, so the list of extras is growing.

I did a quick test of the current version to check grain and vignetting at lower f/stop settings. I did't plan on posting it, but you can check it out in the link below. It is around 22MB and slightly boring. At f/16 - f/22 the adapter had a problematic hot spot/vignetting. It sometimes showed up at f/11. The images also seemed to get a touch brown with the higher f/stop settings. The test was done with a Canon 50mm 1.4 lens. I will be testing the adapter with a Nikkor-SC 50mm 1.4 next to see if there are any improvements.

http://www.snodart.com/snodpublic/DIY_GG_Fstop_tests.mov

Keep in mind that the first test was done with only one Lowel Omni light and the outside tests were done on a overcast day. I made sure to keep the camera moving across solid colored and light areas to help reveal any hot spot or grain issues. I noticed that the redrock micro's sample clip of the M2 at f/1.4 - f/16 did not do this.

I have decided to include some of the parts with the first 50 DVD's, and maybe more after that... not sure yet. The purpose of the included parts would be to help DIYers avoid the often high minimum shipping costs. An example would be the required screws/nuts for the lens mount.



I have been working hard to ensure that the adapter is easy to build and modify as you choose. So a few updated advantages of the Snod35:

With the tools and parts in front of you, the adapter could easily be built in a day.

You will be able to change your GG to whatever you want. The DVD will go over making your own GG (the one that is used in the test clip), but you will have the option of using a Nikon D screen, beattie, translucent plastic, or whatever else you may choose to try (or maybe already have).

Also, the adapter is set up so that you can quickly and easily swap out lens mounts. Adjustment to find infinity focus with different lens brands is quick and easy. So, for example, if you have a Nikon wide angle and a Canon 50mm, you will be able to use both.

The image plane (GG) is easily accessible for periodic cleaning if required.


We will also be setting up a side-by-side comparison with the Snod35 and the M2. We are still looking for DVX/M2 owners in Souther California that might be willing to help with this test. If anyone is interested in helping, please PM or email me.


I am hoping that the DVD will be ready to ship before the end of August.

EDIT: BTW twocik23, the motor did not prove to be powerful enough.
