As a failure analyst back in the 70s, I spent years looking at chips and taking photos. Today's chip complexity is orders of magnitude higher. No hope of tracing one out completely. The Zeiss scopes we used were obscenely expensive but very nice.
I'd love to see a video on all your customizations (stepper motor controlled anything). I have quit a few microscopes, most of which I put together from parts bought off of eBay (I could never afford anything direct from the manufacturer). It's all great fun. Your work is great! I was troubled to see a few comments on another of your videos by people who don't understand copyright law. They also don't understand the "art" market. Anyway, keep going and good luck.
The cheap digital microscopes use a CCD (charge coupled device) to capture the image. They can call it 2,000 max magnification if they want, but it will only capture to the max the CCD will and what the electronics support. It was probably like in your initial review that one of them had a CCD that supported higher resolution, but the electronics only supported the .3MP so was limited to that magnification. This is like the majority of electronic and lighting stuff on Amazon, from China, which is BS.
I might already have some, I'll have to check and see. The flip-chip style silicon dies like these on the Transmeta do make viewing the chip difficult, but I'll see what I can do. :)
Resolution is also limited by the optical aperture. Similarly with telescopes there is a diffraction limit that is determined by the optical system's aperture size. The smaller the aperture the less resolution you get.
Brilliant video! I am not the perfect audiance for this subject as I am not as curious to discover chip dye features, but I am interested in a moderately priced solution for smd soldering and inspection, where none of the dirt cheap options offer any handy slider boom.
You can have a higher resolution sensor, but behind the same lens you night be limited by the quality of the lens as well, this video btw.... Very very helpful since there is so little to find about these microscopes because this is kind of a niche.... Thanks m8
Came across the video while searching for info on that really cheap USB thingy, which ends up looking like just the part for what i need it for, but then started wondering. Did you ever use "mean stacking" on sequences of images taken with you professional gear? And does it make any difference in image quality? It makes quite a difference with cameras, from cheap webcams to DSLR's, but microscopy might be different.
I use a tomlov microscope that was purchased on aliexpress for $250 or so and I love it. I use it mostly for soldering so it works for me, not sure how it would be for checking out microchips, maybe I could get a lens to make it zoom in that far but with the few lenses I have now there is no way I’d get the kind of detail I see in your videos.

Makes me think that I'd get a better result by buying a lens or loupe attachment to the phone camera. Good chance it's got a better optic chip.
Congrats on the UA-cam levelling up. Look forward to your stepper motor and replacement light videos. Subscribed.
Can you open an ESP32 microchip to see the RF Cmos wifi transceiver? Thanks
I really really hope you can find a transmeta chip. Trust me you won't be disappointed with the chip art. Specifically the 0.18um TM5600 and 5400

Do you remember when the internet figured out the resolution, lens dimensions, and orbit of a US keyhole spy satellite from just one leaked picture
@@godlugner5327 no idea, but known fact that Hubble is slightly modified KH-11, and all data is well known.

Can you recommend what to use for examining knife blade edges?
Fascinating video! I have learned a lot!
Tomlov was surprisingly good for a digital microscope. Would you say it would be good enough for use with electronics repair and soldering?

Sir its a possible to make copy any ics ?
I really wish you could put a modern camera ccd sensor under 800x or more magnification. I really wonder what the induvidual pixels looks like
Generally speaking going for optical magnification should be better. Then a nice high resolution capture
nice share-great hobby-learned alot manythxs
15:16 try a UV/near UV LED. Shortest wavelength should give the best resolving power?
Carson has a pocket microscope model with a built-in UV light, but I found their colors were inaccurate when photographed
perfect, thank you for sharing
Did this with a handful of different microscopes... The USB only one's seem to be only the best
Perfect 👍

wonder how good the samsung isocell hp2 200MP in the s23 ultra would be consider the s21 looks very good to me already.

👍👍
The only one thing i want to see is he do a test on AMD Threadripper chip
That hair was not free. There was a tariff applied.
It was pubic in origin
hi handsome, could you upgrade your microphone, to a rohd? thanks. more video's please.
THX 🙂👍
I don't like the layout of this video...But it convinced me to not buy a dedicated microscope camera.
"Resolution".... 3:23
Waste of time. All of presented microscopes are the same model with added features. Scope of selection should be wider.
Your work rocks!
Thanks! That means a lot :)
