Vibrating glass
 

Alright guys, I'm going to apologize straight off in advance incase this has already been discussed to death.

Come to find out my uncle is an Electrical Engineer and he also knows a few Mechanical Engineers. So I wanted to ask, does anyone here know in brief or in detail what you have to go through in order to get the Diffuser to vibrate properly? A link possibly? That would be freaking fantastic if you guys could help out.

The vibration is done with a motor with an offset weight, like the ones used in pagers or cellular phones. Here's a picture of one from a Nokia:

The Letus uses rubber parts from syringes, to make the vibration within a specific range. Unfortunately I can't find the Letus guide anymore (had it as a .pdf).

The cylindrical motors with an offset weight can be quite noisy. I am personally using a small disc motor, which is quite silent once enclosed. If I am not mistaken, this is also what is now used in the Letus.

They are a bit tricky to solder though.

That is so cool Quyen! I can't believe you still distribute your older plans. Obviously they've changed and improved, but I think it's great that you still do that. What a gentleman.

Francois, how would one go about using such a motor? Do you have any pictures of the way you have it mounted? I'm interested in making a vibrating GG but don't know much about motors and such. Very eager to learn though.

No pics yet, however, it looks a lot like what you see in the tutorial, except I have three posts instead of four and the disc motor is glued to the GG support plate.

Soldering the wires to the disc motor is the tricky part. The best way to do it, IMO, is to glue the disk motor and wires (cut at the right length) to the support plate before you solder.

I think you will find a lot of tips in the initial thread by Quyen.

BTW, I also thank Quyen for sharing his great ideas.

I looked more closely through Quyen's instruction file and it does seem pretty straight forward. I'll get things assembled in a static manner first and then see about adding a motor soon after. Looks really cool though. How much power does one of those little disc motors take? I'm no electrical engineer, that's for sure.

This file is not mine. I believe Craig made this pdf file. I am glad that you can build it yourself. I only sell to people that don't have the necessary skill or time to put it together. My current unit uses coin motor and has most of the parts done by CNC at a local machine shop plus all the updates, so the unit in the guide and my unit now is quite different. Hope you enjoy building it if you choose to do so. Also please keep in mind that my address and phone number on this file is out dated, thanks.

Anyone know if this motor would work? Not very much info on that page though... But for all of us living in EU and Europe it would be preferable to buy as much stuff "locally".

Man, thanks a lot guys...you really helped me out. I have a question for you Quyen if you don't mind, you don't have to answer, but I heard back in some other forums you chaned that type of sticks to vibrate the glass. Do you mind sharing? If you don't want to, that's completely cool, I know you have your business to run. I'm going to run this past my uncle and see what he can do. I'm going to look around for some custom fiber glass places to shape exaclty what I'm looking for. I'll see what I can come up with.

My sticks now made of aluminum. I have machine shop machined it for me at exact length so I can have the same spacing between GG and mount. There is nothing to hide here really but it will depend on what you will use for your mount holding and the distance between GG and that holder. Some testing will give you optimum vibrating GG plane. Plastic sticks still work OK, thanks.

how those cellular motors have been behave by long usage? Somebody got to replace it already?

what happened to the .pdf?

Sorry about the PDF....
 

I was running out of space on my servers and hadn't seen anyone using the file in a while... I'll see if I still have it some where... Sorry

PDF---Got it back up....
