Le Naturaliste

Yes Patrice, sadly, I know him and his ego...... He is not well seen in our italian community for the reason you probably all know

OUi, Franco, nous en avons aussi notre expérience !

Sì, Franco, ne abbiamo anche la nostra esperienza!

Plus sérieusement Franco,
Magnifique travail que tu nous présentes

Hi,

Verry beautiful work, and what a terrible microscope !

You've no problem to drive the prior stage?

Sublimes photos !

Thank you. I can drive the motor at very low speed, but not that smooth as it is supposed to be with an original controller. Considering that I bought it for 100€ it's fair enough!

Welcome Franco !

Impressive work

This is also my first time seeing such sophysticate pneumatic system around a microscope

Hi Franco and welcome,
as I don't speak italian, I think that english is the way to communicate.

The 3 diatoms slides are a beautiful work. All are very nice.

The "phomi" Zeiss is alone a big microscope but with the motorized stage and with micromanipulators around, it is very impressive.

I have 2 questions:
Can you please write more about the arduino for the prior stage? Can you communicate your work?

As Pierre4fun, it is the first pneumatic micromanipulator system at work not arround a resarch microanatomy system that I see.
Was it easy to find it and to make it work?

Best regards

Thank you Pierre,
the pneumatic micromanipulator is a "Micro-manipulator de Fonbrune" which I bought on Ebay for around 150€. It arrived with the frontal bellow of the probe moving unit broken, because of poor packaging. I had to fix that with soldering and structural glue and of course I asked for a refound to Ebay (global shipping from USA was used). It's not too rare piece to find on US Ebay for reasonable price, around 200€ and it's easy to use!
I also have a home-made "frankenstein" mechanical manipulator which works just as good as the other one, made of spare parts I had at home. It's very heavy and stable. The movement in the Z axis is given by the old focusing block of my Universal, which I replaced with the stainless steel version on the scope.

If you want I can give you all the informations about the stage and Arduino project and the code. But maybe I should open a new post in the proper section of the forum!

Of course I can't use the mechanical stage for arranging Diatoms because it doesn't have the precision and responsiveness of the hand moved one! Nothing can replace the touch of your hand! I am fascinated by how Mr Kemp moves the slides just by hand, without using the knobs of the stage, when arranging Diatoms. I really have no idea how his hand can be so precise without the use of any mechanical device! Chapeau to him!

Thanks for answer about micromanipulators.
Sometimes I look for that on EB but I founded only mechanical micromanipulators for 200$
Hydraulic systems like Narishige are ten times more expensive...
It is possible to do a lot of work with only hand, but what an acurate job!!

I think that I am not alone to be interested by arduino and step by step engine.
