She has said she uses obliqie to get these kinda of results. It could be, well tuned oblique can be very good. I went back to compare the DIC vs her version: https://www.youtube.com/watch?v=5W0XMM7DQ-E&t=275s DIC https://youtu.be/HbwV-EzP67Q?t=84 I think it is indeed oblique illumination rather tha...

I don't want to throw accusations around without proof but I highly doubt that only a ba310e was involved. https://youtu.be/5W0XMM7DQ-E?t=108 https://youtu.be/5W0XMM7DQ-E?t=275 All look like DIC The sparkle is polarizer (+DIC?)

Not my post nor my item! I just saw this and thought it was interesting and would share with people who could fit this huuuuge microscope in their house.

Item located in south France

Hi all,

I got this in a "bundle" and have no idea what this is. Maybe some epi illumination device ?

Lovely. Thanks for sharing.

Saw that bad boy on the French website leboncoin.fr.
This is not my item, I don't know the seller. I just thought it was interesting and could be of interest to someone.

he made this list could be a bot

I am curious, how were you able to identify his IP?

I think I will just put a modern 0.1uF X safety capacitor in there and see if the magic smoke arises or not.

The inductive load is quite small in this usage

I was wondering on that matter: isn't the transformer coil a pretty large inductive load?
Frankly if it is signal filtering, I will do without. If it is for spark prevention, I would rather have it in there.

Thanks, not sure how similar the mechanisms are. It seems counterintuitive to me that there is not a simple tension adjustment... I must be missing something

Hi all, I mentioned this issue yesterday in another thread but thought if it had its own thread. I am having some issues with a BH sample stage and was wondering if someone has an idea. I couldn't find anything in the BH manual that mentioned a solution to this issue. The Y axis (the big knob), when...

99% sure I damaged my left eye using a led source that turned out to have high uv.. the only reason i didn't damage both is my right eye was all fogged up with blood from a internal blood leak. I was right eye blind for about 6 months.. now the right is better but the left still has a greyed out ar...

Bruce Taylor (of this parish) had a very similar problem in 2013

Thanks. So the mystery remains. What is that for? I think that it is to avoid current discontinuity and sparks when the switch is turned off.

Found a guy with the same issue here:

I think it is 0.1uF from the burnt plastic cover...

Edit: Moved to a new thread

Hi All, Does anyone know where I can find a replacement capacitor for this little guy who probably burned a decade ago. I could read "Marcom MP something 500 wv.dc something". Thanks! I think those are used to avoid sparks when turning on/off? Since nothing bad happened I presume this component is n...

you can buy those too:

I have a couple of those if you are still looking

Woooo, sorry to hear you had a stroke . Glad you are back and hope you a swift recovery to full health.

You guys made it possible. I did find that the cura seems to like short file names and I ordered a new roll of pla because I've been printing all day. Hoorayy!!Hooray!!! :lol: :lol: :ugeek: I am 6 months in and still on my first 2 kgs of PETG and PLA. How are you done with one roll in a day? :lol: ...

Power off and on the printer while keeping the card in. I noticed in my printer that, new/all files were not recognized/read when I insert the card after it is powered on. It drove me crazy until I found the workaround.

You can refresh in your printer's interface.

It came with a USB but the printer isn't recognized that way so why have a USB connection? I think the USB port can be used to be printed directly on but it is not worth the hassle IMHO. The printer doesn't seem to recognize the stl files. Cura slices the stl files into gcode. By the way, there is ...

I've ordered plenty of pla

Beware, once they are open, they start to suck moisture and printing will get harder (bubbles, adhesion issues potentially). Don't open all at once (if different colors)

Yes, my first was really stuck too. If you print PLA, don't heat the bed beyond 40C and it won't be as bad. But too much adhesion is a good problem to have, much easier to troubleshoot than no adhesion and warping of the object. And be careful with that magnetic detachable bed top, it doesn't handle...

Attached some Freecad source files I made as examples. I was too lazy to make it parametric but it should be easy to adapt.
Dark field and oblic filters and an extension tube for DSLR adapter and 30.5 mm tube.

I was able to install freecad and cura. Ordered an Anycubic Mega and pla which will be here on the 20th. Nice, the adventure has begun.

Hi Greg, I started the 3D printing adventure late last year. It was a fun experience and actually pretty inexpensive. I was able to make some optical tubes and other things. My stack below: CAD software: FreeCAD. It is free and opensource. Plenty of tutorials on Youtube to get you started and powerf...

Thanks. I am now much more knowledgeable on the secret life of Duke.

Wait, how did you convince Duke to... you know, dunke?
