I am trying to guess. The stage motion must be controlled by reference to a pre-defined "zero" starting point. A "reset" position. Possibly, pressing the start button sends it to this reference position. If that is correct, then pressing "start " after the stage has been moved with the joystick to ...

I can imagine that this stage has been sold over a microscope manufacturer. Maybe you can find information after you have found out for which microscope it was made? Good idea, but I feel like I have exhausted all information avenues. I'm not sure where to go next. It does fit my Nikon TMD, but I d...

Simply amazing Glen ! Do you use a micro manipulator ?

I should say that for my uses, the joystick works just fine. I do a lot of scanning and this makes it so much easier than reaching back and turning those knobs. I'm happy to have this and hope it can last a bit longer.

There are several switches like the one in the photo 1. IMG_3457.jpg I have no idea what they do, but I cant see anything that looks like a photo detector. That looks like a simple mechanical ‘microswitch’ MichaelG. . Edit: it may possibly be that this is the successor firm to lang-elektronik https...

I can't help you with the repair but this is an interesting item for sure. It would be interesting to use it to shoot a batch of images that then can be stitched together. If these are stepper motors it might be possible to exchange the complete contro box against a control board of a 3D printer. P...

Thank you Hobbyst46-- I'll experiment with your suggestions. First I have to get the y axis to respond.

From experience with other stages: likely the stage has two photo-cell sensor microswitches that mark the ranges of motion, X direction and Y direction respectively. It is important to install them in the exact original positions. Thank you ! There are several switches like the one in the photo 1. ...

I've just acquired a Lang-Elektronik MS 317 motorized x-y stage. I'm wondering if anyone has any experience with this ? I located the German company that made it ine the 90s , but they have since purged any info. I have the joystick working now, but I had to fix an electronic issue and take the enti...

Stentors are cool ! Thanks for sharing these.

Nice and clear videos, thanks for sharing !

nice video Chris-- Thanks for sharing . I've been seeing a lot of testate amoebas lately, but they have been pretty motionless. Nice to see one waling around !

I vote for more info on mintakax's "tiny capillary pipettes" and how they're used, preferably with pix. :geek: Haha- I was having trouble with a regular bulb type pipette in picking off individual ciliates from a larger sample viewed through a stereo scope.The bulb pressure between my fingers kept ...

For what its worth, I have frequently used a stereo microscope to view a large sample and then used a tiny capillary pipette to transfer one creature onto a slide and then add a drop or two of clear pond water. The technique works really well and the capillary pipettes don't require any manipulation...

I know next to nothing about microscopy polarization, but those pics look pretty cool !

Nice and crisp video of this fascinating creature Chris ! I have a large population of these in my tank as well.

Mintakax, amazing videos! This one looks a lot like a Nikon Small World Winner: https://vimeo.com/369062481 ...it is no single celled anything, it is a dinosaur that survived the K-T extinction!!!! ...one question, if it was for the money, clear. But if it was about technology, optics, could you pl...

The mere fact that an organism, however small and whatever it does, exists, justifies its existence. I sometimes have the same feelings as the topic starter. We place micro organisms between two pieces of glass - where they certainly die - just for fun, no other reason. Same as fishing for fun and ...

I make every effort I can to minimize the harm I may cause the organisms that I observe and culture. Why ? Because I care. Caring about other beings doesn't have to be rationalized or described by any relative analysis. It isn't even a choice, it's just how I have to do it. All beings are governed b...

I hope you enjoy your DIC BHS/Bh2 ! I've just sold mine, but not because I didn't love it. If you want to see what "average" videos look like through this scope, check out any of my vids on the pictures and videos section (pre 12/15/19).

Tom,

This was shot with a Panasonic GH4, in 4K, using my BHS and the same DIC set you just bought: https://www.nikonsmallworld.com/galleri ... er-feeding

Hot Damn Tom. That Nikon small world video is amazing !!

I just bought one just like this- has anyone used this with a Macbook computer? Can the images/videos go from camera to hard drive via the USB? I've been manipulating my camera through the menu that appears through HDMI on a monitor and then taking the card to my computer. The camera came with a US...

My usual camera is at Nikon for an upgrade and I was looking for something I could stick in an eyepiece tube of my stereo scope so I bought one of these from Amazon for $124. Honestly, for the money its pretty decent. I took some stills and some focus stacked pics with it but don't have a photo site...

Thank you Wes ! I have no idea what the flagellate is and to be honest, there are scores of different creatures I see from my aquarium and cultures that I have no idea of their taxonomy apart from ciliate, flagellate or amoeboid. My aquarium is pretty simple. Its a 5 gal in my garage with 6 inches o...

Did you find the 100w BHS to be a microbe-boiler?

The samples certainly dried out much faster with the 100W , but I honestly cant say that I saw any creatures being harmed by it, I just figured that they were.

I have put Nanodyne LED units on both of the scopes I've used (Olympus BHS/BH2 DIC and Nikon TMD DIC 100W ). Both scopes came with 100W halogen. In both cases the LED was substantially brighter. I mainly went with LED to avoid heating up organisms, so I was less concerned with the photographic aspec...

Awesome video, thank you ! I've seen two of these in my tank when it first started but nothing since. I'm curious Chris, was this a well slide ? Also I would very much appreciate to see details of you tank ? There is a lot I need to do differently on my own tank.

Really nice job capturing that action ! Poor ciliate seemed to be sleeping until it was too late. Life feeds on life.

Thanks Kurt

Thank you Glen !
