Has anyone tried this USB scope? General macro chit chat appreciated.

Not at all. The systems are quite analogous, though they don't map 1:1 of course.

Of course, but the apparent sizes of what the eyes see thru glass optics is completely analogous to the apparent size those same eyes see when looking at a computer monitor with a similar image.

Please, why do we keep coming back to the SZ7? The pod has a zoom ratio of 7:1, and this is why it is called a SZ7. But it also (by happenstance or design) has a magnification range from 1x up to 7x.

The pod provides an aerial image that is magnified by the eyepieces for viewing with the eyes. That image could also be projected onto a camera sensor instead. In the first case, the optical magnification of the pod, multiplied by the magnification of the eyepieces, will set the total system magnification. In the latter case the magnification of the display monitor replaces the magnification of the eyepieces to set the total system magnification. These are completely analogous.

One thing I have not stated, and it may be the key to understanding this, is that there is an assumed viewing distance from the monitor that gives a standardized way to calculate these magnifications. I leave it to the interested reader to explain how this distance is determined.

Ahh, but physical devices such as IC packages, or display monitors, are indeed mechanical objects. Many of their properties obey the laws of mechanics, and they have 3-dimensional form.

There are many "domains" or "layers" in this world...optical; electrical; digital; mechanical; spiritual; the list goes on and on. When you are talking about physical objects, you are in the mechanical domain, or the physical layer. Of course, physical objects could have aspects that exist in other domains as well, and that makes things somewhat confusing for such a complex object as a display monitor.

As long as you don't mind looking at everything on the monitor instead of "bare-eyed," you could pretty much duplicate my entire imaging system for around the cost of the cheapest Aven Mighty Scope. It's one of the major reasons you see people proselytizing about the cheap dSLR/duplicating lens concept - it's cheap.

 

I've never really looked much at Aven, but I'll look closer as they seem to have a wide range of interesting products. I expect they are probably made by the same
Chinese factories that make Amscopes and the like.

 

I'm not exactly sure what this means exactly, but, it sounds like relinquishing the pleasure of my eyes to view stereo magnified images of images to be photographed or displayed for sharing with others.

rmpsrmps,

Your photography work products are impressive, admirable and inspiring. Thank you for your patience in explaining.

I am coming to realize the nomenclature, conventions and designations are items I'll have to look into further.

All machines are devices but not all devices are machines. A computer is not a machine unless it is a mechanical computer/counter etc.......

Mechanics.

1. a device that transmits or modifies force or motion.
2. Also called simple machine. any of six or more elementary mechanisms, as the lever, wheel and axle, pulley, screw, wedge, and inclined plane.
3. Also called complex machine. a combination of simple machines.

I am curious as to at when point in time electronic devices and their static functions first were designated or referenced to machines or mechanics.

I am aware lots of things have changed in the field of electronics and frankly, I have no idea how electronics can work with Common Core Math capricously and arbitrarily removing the order of operations, for starters.

Then again, the Core 50 Master's degree requirements to teach History under the core require one to blindly buy into and teach that this nations 'founding fathers' penned a document titled "The Constition of the United States of America". No, they did not.

 

I have an Andonstar usb 'scope. Comes in handy when I need to blow up something tiny---like the die clash error on an 1880-CC Morgan VAM 7a.

 

I don't think I ever mentioned the word "machine". That word has a very different definition from "mechanical".

Look back at the definition you posted:

me·chan·i·cal
məˈkanək(ə)l/
adjective

1. 1.
   working or produced by machines or machinery.
   "a mechanical device"

Things that are produced by machines or machinery, including electrical components, are "mechanical devices". Thus both the sensor and the display are mechanical devices from this definition.

This is a bit of digression though, since it does little to explain the meaning of "mechanical magnification". Perhaps you can think of it this way...Imagine you were given an image printed on a sheet of rubber. If you mechanically stretch the sheet of rubber in both x and y, you would have "mechanically magnified" the printed image.

 

Now I am floored that you are asserting the two words, "machines" and "machinery" have been divorced from relativity for the seeming purpose of what I see as a bizarre, perhaps not perverse, borrowing of both words without respect for their true meanings.

Electrical "components" are not the same things as electronic components.
May I ask in what general era you studied electronics or electrical? Please do not take any of this as my being condescending as that is not my intent at all. I am trying to grasp my having slept thru what smite me as somewhat revolutionary and sweeping modifications to this field, the English language, and even physics.

The terms amplification or multiplication sticks in this crusty noggin as being more appropriate. I may be splitting hairs relative to this academia.

 

My degree is in Electronic Engineering, and I've spent most of my career building Power Amplifiers for cell phones. The cell phone you use today probably (90% probability) contains Power Amplifiers and other components that use both device and packaging technologies I helped to develop. I'm currently working for an RF MEMS company. As you might imagine, MEMS takes the concepts of "mechanical" and "machine" to a whole new nano-level.

One of my responsibilities (I work for a startup, so I wear many hats) is the reliability qualification of the MEMS devices. These qualifications have many aspects, but most relevant to this discussion is the package/mechanical qualification. We qualify the mechanical characteristics of the MEMS package under many conditions: vibration; shock; acceleration; thermal; moisture; aging; dimensional; etc.

 

Thank you and your de facto cirriculum vitae is impressive. Just the same, I remain without a general timeframe as to when these changes, or your formal education, occured. I am not doubting one bit your candor or veracity.

I cerainly am also not taking you or your fine results to task.

However, when I was educated in the field, "mechanical" or "machine" were never terms used with respect to electronics. Electrical? Yes indeed.

So perhaps you can understand how this would strike me as a dizzying revelation, if not somewhat bizarre adulteration of our language?

FWIW, I went further and studied other areas of engineering, science and law.

I have a good friend that is a brilliant fed atty that also does hi-tech patent work. I am sure we'll discuss this topic next time we speak.

I certainly do appreciate the sharing of information and ideas.

A semi-tangential aside, although referenced in my original post; have you ever played with stereo fixed digital cams outputted to a 3D monitor?

 

I bought a Digital Microscope from Amazon for $49.99. I didn't expect much, but I was pleasantly surprised. I just gave a coin club presentation on error coins and the scope did a great job on zoomed in on over-dates, die clashes and other errors that you would normally need a loop for, and they were projected (Power Point Presentation) onto a large screen. Negative- it cannot give a image of the full coin, only close-ups of parts of them. The box says- "Digital Microscope: HD Color CMOS Sensor, High Speed DSP, 24 bit DSP, Optimum Resolution 640x480, 5x Digital Zoom, Contains Digital Measurement Software and Calibration Ruler, Compatible with USB 2.0 and USB 1.1, adjustable stand or handheld.(my laptop is a HP Windows 10). Do I like it? Yes. Did the club like the close-up images being projected-yes, did I like the price-yes. The scope also works via wifi for phones and tablet. I'd consider it one of my better buys.

Here's a sample:

 

Thank you, what magnification range is it advertised to have?

Can you show lowest and highest magnification comparison pictures of the same subject? Impressive for 0.3MP, 49 bucks and with a wifi card too boot. Have you ever considered placing de-magnifying glass between its lens and the subject to obtain a longer working distance and wider field of view? Like 0.3 or 0.5 marked optics?

 

They claim manufacture in Japan (who knows maybe assembled there from Chinese Child Slave Labor made parts?) and slightly infer they use nikkor or olympus optics. The claim of MIJ came from one of their videos, I forgot where I picked up the lens inference.

Some of the design is elegant in its simplicity resulting in an interesting reduction in moving parts.

 

I have never tried such a thing. My wife can't deal with any of the 3D technologies so we don't have a 3D monitor in the house. No monitor=no impetus to experiment.

Interesting! I will look further at their website.

 

I'd like to hologram a coin.

I look forward to your perspectives after checking out the design. I don't need one, but, I can appreciate what it appears they have pulled off. However, their marketing is patently devoid of some basic and fundamental specs as well as function details. ie.... that is a c-port in the third hole and do you or do you not lose stereo view when utilizing the third port. I certainly wouldn't buy a used one to make a determination.

 

A coin hologram would indeed be cool.

I checked out the Aven website, and the scopes look good, but for 1/10 the price I'd prefer to go with vintage B&L systems. Maybe the performance isn't quite as good, but it's pretty good, and I hate wasting $. Interestingly they had some tools I was looking for, so I'm happy to have checked them out.

 

I bought one quite similar from possibly the same place in China. I found it to be about useless and just tossed it. I do much better taking pix of coins with my old Nikon Coolpix 3 on a home made stand.
