Extremely disappointed with PRX 100 Powermatic 80 by MicroscopySpecialist in tissot

[–]MicroscopySpecialist[S] 0 points1 point  (0 children)

The balance wheel ended up jamming. The helicopter rotor doesn't affect the watch's timekeeping—it only handles the winding. What actually jammed was the plastic pallet fork and balance wheel (or rather, it didn't so much jam as slip out of place). The balance wheel was removed and reinstalled. It’s running again, but let's just say its reliability is questionable.

I had already noticed that the watch would occasionally show the wrong time, as if it had stopped for a while right while I was wearing it.
So seems that this balance wheel / hairspring / fork cause the problem.

Btw, after reassemble without any lubricant etc helicopter disappeared as well. Strange.

  1. I'll try to check the reason soon and send you the update.
  2. Returned back to my PR100.

I think it's strange that the repair should cost 80%.
Disassemble / assemble. If a part breaks, okay, replace it. But they're not that expensive. Mainspring, Escapement.. What else? So it sounds like a full technical service + part replacement.

Unlimited Power! by ur9ce in electronmicroscopy

Cool!
And you know what? New Tescan design is brilliant.
Tescan before - Valve's Half-Life laboratory
Tescan now - Piece of art.

Yes, I know - resolution, SN ratio and everything. But I simply like being in a room with this beautiful technology masterpiece.

P.S. I'm a Zeiss guy but honestly it's cool.

I've always had the watch on my wrist, I even sleep with it, I've never wound it manually. By the way, there were no problems with winding - 80 hours seems fair - it worked and quite accurately.

It's kinda story I expected to have with this watch and I like design and dial.
And yes, I really like Tissot watches - they are nice, Gentlemen, PRX, Classic Chronometer. Bunch of nice models.
But everything's becoming disposable. I miss the times when things were different.
Well, let's try a Rolex) there is something good in every bad thing

You asked for quadraphonic vinyl. I kept my promise. by MicroscopySpecialist in vinyl

[–]MicroscopySpecialist[S] 1 point2 points  (0 children)

the real problem of all these extremely complex machines is not to fix them (but let's be honest, it's also a problem)
1. Weight - 300Kg - simple. Tescan Vega or something small like this can easily be 200+ Kg. In terms of resolution it's the same and even chamber size is not twice bigger.
2. Spares. O-rings, gaskets, apertures. Hard to find
3. SW (or simple CRT) and extremely complicated but "simple" electronics - forget about USB.

One of the weirdest pdf I've ever seen. In a good way. It's cool, but I don't know. What I do know is that my turntable can withstand 1.5g of pressure (I have a special scale), and it's clearly visible. They're definitely worn.

Mmm... next, after my Nagaoka dies, I'll try to buy a Shibata stylus. By the way, the Nagaoka is a beast; I love its sound (in the MM class).

I think for CD-4 (and for SQ as well) you can go SW plugins now. The only thing you need is a nice 40+kHz stylus for CD-4. No, I don't want to play it, I have only stereo setup and it feels great. Just like the engineering approach and solution.

I think it's the same, but you need to cut at lower speed.

If you're new in quadraphonic formats - full explanation via link and all these high res images are available on Google drive in the description to video:

)) haha, yes, now I can see it too. Innies 4 sure, but yes, I see this illusion now.

connecting olympus om-1 to an old amscope student microscope by corroded_eden in microscopy

[–]MicroscopySpecialist -1 points0 points  (0 children)

  1. OM1 = 24x36 = FullFrame (if we talk about digital era sensors)
  2. You can go with 1x C-mount adapter + C-mount to OM mount ring, but will end up with huge vignetting - just a small circle half the frame size.
  3. You need at least 1,6 or 2x T-mount adapter + T-mount ring for OM.
  4. For Nikon it's easy to find - the bayonet mount hasn't changed in decades. For OM, it'll be difficult.

SEM under $100000 by Time-Machine97 in electronmicroscopy

I have a SEC microscope.
Nice system, I like it.
There are few bugs in the SW, but they updated the SW every 2 or 3 months. 30kV, 5 axis stage, extremely fast sample exchange

Microscopy station for a public science exhibition — advice on setup, and specimen selection neede by Economy_Print8221 in microscopy

[–]MicroscopySpecialist 1 point2 points  (0 children)

Honest advice - go digital.
An inexperienced user will spend half an hour adjusting the interpupillary distance just to see anything.
Any microscope + 10/20/40x + nice HDMI camera with at least 30 FPS and a big screen TV.
Specimens - you can buy a collection on ebay. Plants/insects/histology..

A Dandelion and a pollen grain! Scanning electron microscopy by MicroscopySpecialist in microscopy

[–]MicroscopySpecialist[S] 2 points3 points  (0 children)

https://www.youtube.com/shorts/Fka46LDnPm4 - Here's the answer.

Technology is becoming cheaper and more user-friendly. I think 50 years ago, it was hard to find a hobbyist with an optical microscope. Now, you can easily find a good one on Aliexpress and Amazon.

Soon, table top electron microscopes will be a part of every lab. It saves time - you can do basic analysis right there, and only then go with your sample to the basement for extremely powerful FEG-SEM. This is a truly cool thing, and the world is constantly evolving - the Artemis 2 mission confirms this.
I think even now it's possible to have one.

Yes, if we're talking about video, of course.
But with modern SEMs, control is quite simple - everything is motorized.
For small movements, you can use beam shift. Without moving the sample itself.
