Have you considered using cheaper stepper drivers like the A49xx or DRV8825?

Hello; so I'm currently working on modifying this design for a de-airating device, and was just wondering if there was any particular reason you guys chose to put the tubing the way you did? Like was it the most effective positioning to have it rotate from that manner?

This is great! You should consider submitting this to Tekla Labs BuildMyLab Competition: http://instructables.com/contest/buildmylabinstructables.com/contest/buil...

Wow that is very nice thinking. Grats!

Hey there nice design,

I'm a biology student from the Philippines, I and my groupmates are doing our undergraduate thesis and we included an orbital shaker to our methodology... We were ignorant back then that we did not know it costs a load of money just to RENT one.

So we're considering on building one. The thing is,
we're gonna mount a lot of conical flasks... numbering at least (30) 250ml erlenmeyer flasks.
O_O

So you think a large scale version of this is feasible?
4x4 ft or 5x5 ft?

When I try to imagine it, won't a bigger version lead to a greater and more dangerous "tilting" of the mount? Or are my eyes
just fooling me.

interesting idea! yeah i think it is feasible... you probably want 1 large motor and a level shaking instead of orbital shaking. Orbital shaking of that large a volume will be very top-heavy relative to the motor itself (that much liquid will surely weigh more than the motor itself).

Let me know how it goes or if you'd like me to take a look at your design just post a link to it back here in a comment. Would be great to see your design as a work-in-progress up on thingiverse!

Actually, I was hoping if you or the chaps here could have an idea how to make it level-shaking. So far your design is the only one we'd found, and I was wondering if it'll only take a few modifications to make the thing level instead of orbital.

This is beyond my expertise as a biology student. So at the moment, I'll approach our College of Engineering or Physics professors if they'd have some ideas to modify it.

This is awesome. Has someone tried using it for liquid in vitro plant shoot cultures yet?

interesting application! i don't know that area much... do you have to shake plant cultures to keep them alive? This should work fine for that application (if the plant shoots are small).

Do you think it would be difficult to modify this into a "shaker table" model like the one pictured here (or like MtDon mentioned):

I suppose the same electronics but a bigger single motor might work.

That is pure genius showing ingenuity. What an elegant solution.

Very cool.

But, do you need individual motors for each container?. Can you use a single motor to shake one larger platform on which you could set the individual containers? The platform would, of course, need a way to attach the containers to it.

that design would certainly work too. We did it this way because we want the ability to have each plate shaking at a different speed. So 1 motor per plate is the absolutely least expensive and simplest way to do that.

That makes sense.

HI!

Cool design!

I am interested to make suach a shaker.

Is it possible to make it work on batteries, since we dont have a plug inside the

cell culture incubator for the power supply?

Thanks a lot in advance,
Best wishes

just run the motor connectors out of the incubator. that's what we do!

Very awesome stuff! Really inspired to see this design in action, hope to see them on Ponoko soon!

Thanks Cathal, I was definitely inspired by all your open source hardware projects!
