cheap vibrating GG mechanism

Mandy,

The rubber band version is just for "quick fix". People can try it instantly but it looks ugly and I think it won't last. The second version is far better and I build it inside the 2.5" square tube. I use mostly custom parts I made from my shop. I am thinking of getting conventional parts that can be bought at the store such as Home Depot or online ... I will upload the picture of my adapter later. Thanks.

i should say it is really convincing.
obviously your GG is low quality (when stopped) and the result (when shaked) is really great.
currently , i am obtaining with my static GG something close of what you get when vibrated, but i am looking for HDV, so it i really need to move my GG a way or another.
now we are started for a new thread about comparing different kind of gums, plastics, silicon (my best guess) to do the job.
I think i will try with another actuator type (motor are too heavy and big)
something like the crystal of some headphone (if i still can find some) or other piezo stuff with an simple oscillator should be better, especially you can put several of them to shake in several directions.

if you are looking for more serious device , google with "piezo actuator"

The BACK picture does not work. Maybe a spelling error or capitalization? The link is not working at all.

The pager motor is not heavy, it's 2.9 gr. I like the coin type motor. I have a quote of 100 of the 10mm 3v motors for about 3.75 each plus shipping. I think it's perfect for this setup. The one on the website you posted is .55" diameter, it's a little too big.

Mandy

The link is fixed.

Below are info of my adapter.
Grommet used. MR 200-1097 at
https://www.westernrubber.com/mainframe2.aspx
Drill size use for syringe's rubber: .154
Drill size use to mount grommets: 15/64
Drill size for 7mm motors: .272 (size I)
Distance between lens and GG 1.65"
Tube size is 2.5" square with 1/8 wall thickness. Length will depend on what condenser you use and what camera you use. Mine is 3".
GG is half of microscope slice.
Ground Glass plain is 2.1" square .065 thick with cut out 1.5"x1" at the center

I will have more pictures with details next week when I have time.

Please ask question and I will try to answer, that way you will know my design better, I don't know where you really don't understand with my design. Thanks.

i think you can explain your system like this.

imagine a table (flat plane over four feet).
when all is ok, the table is rock steady.
now imagine the joint between the flat surface of the table and the feet is loose.
If you shake the table (putting an electrix mixer on it for example), it start to move and shake .
There is almost no vertical movement, since the horizontal movement is very small versus the length of the feet (and this is something you should keep in mind, do not make the feet to short).

Leo Mandy · July 30th, 2005, 05:04 PM

I am a little confused about the picture -
1) do you have a counter weight on the motor to give more of a circular motion?
2) I have a CD motor that I have tried what you are doing and found that it didn't seem to have enough power to vibrate the GG in any real manner.
3) Is the motor sealed GG base - so when the motor is on, the entire piece vibrates?
4) What GG are you using?

Thanks Quyen for bringing us an awesome version of the vibrating GG!

Looking forward to the answers.

1. I use pager motor now and it has off set weight to make it vibrate.
2. What you use to mount the GG base on matter the most. I used to mount it on 4 of the 1/8 plastic without any rubber and it didn't work at all.
3. Yes.
4. GG is half of microscope slice using 600 grit stone stumbling powder.
Hope my answers can help you figure out where the problem is, thanks.

I did some more testing and put 100mm condenser before GG. Camera [) (]GG 35mm lens. The distance between 2 condensers is under 1 inch. No more vignetting. Very slight barrel distortion (don't see it if don't pay attention to it). Focus is sharp. I will do some more testing and will post video on when I have time. Please tell me what to test and I will do it, thanks.

Leo Mandy · July 30th, 2005, 05:45 PM

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.
