Well I ordered from Ali and got this message.

"We are sorry the microscope mount has been sold out, and the new goods will come about a month later."

I will try with AliExpress then. Will have a look in the sellers store first if he has something else worth to buy.

I have no experience with Nikon microscopes and certainly not with this copy. But probably it will be similar to other focusblocks? Perhaps a bit shorter life if anything? Is there anything similar in the same pricerange you would recommend instead? I live in Norway so this free shipping deal is goo...

Well I tried to follow your schematic on page 2. But as I said I am not even literate in electronics. I will order the parts and try on a real breadboard. Is there any risk of me frying the components? Perhaps I should order two of some of them?

Best Regards

First stab at this.

Like I said before I am not very experienced with electronics. Mostly I have used arduinos to control shutter for sync with sound or light and other simple things. I usually buy halfmade shields etc to get that done. Here is my try at making one of the drivers for this speaker on a breadboard. I am ...

Perhaps I am blind but I can only see one sketch? And it says Bi-Directional. It is a sketch on on paper with grid.

trying this out

Hi! Very interested in trying this out. Being quite the novice the electrical field I could really need some help. Looking at making a copy of mawyatt┬┤s drawing. I was thinking of using an arduino and a speaker of sorts, that way I can easily program a simple stacking routine with a optocoupler for ...

Thanks a lot for your help! Is there anything special I should consider when buying lenses for this? Is it only Olympus I should look for so as to fit with the NFK CA correction and perhaps other things? Also I am not ruling out getting some infinity objectives and a 200mm tele if that would dramati...

Yes it is cropping a bit using the 3.3 but this camera (a7s) is fullformat and only 12MP. Even without this crop from 3.3 the sensor would be outperforming the resolution quite a bit. I intended to use a canon 5d3 but if there is no more resolution to get I think I will use the sony for its very goo...
