Title: EEVblog #1125 - Amazing $500 Soldering/Inspection Microscope!
Post by: EEVblog on September 26, 2018, 11:56:24 am
This Eakins microscope from Aliexpress seems identical to the new AU$1800 Suba Engineering microscope for 1/3 the cost.
And can it out perform the $4500 Tagarno?

Price is going up, surprise Dave factor.

Bought one with the link in the video and its $522.99 freedom bucks now.  Maybe its the Trump tariffs.

Funny enough, the camera looks identical to the one Louis Rossman uses.

What are you using for HDMI capture on the PC Dave?

I ordered one from an eBay seller a few weeks back after the previous thread (http://www.eevblog.com/forum/manufacture/new-suba-engineering-pcb-microscope-tagarno-killer/), and it arrived today.

For those trawling ebay the magic search terms seem to be "hdmi microscope imx290", I got mine for ~US$520 including Australian GST, with the 180x lens and a ring light.

The search terms for the standalone less-magnification lens would be appreciated if anyone knows them.

Does this look the same but a fair bit cheaper if bought as separate parts as opposed to the bundle?

Camera Module - ckambiselis worked out this doesn't have autofocus which explains the price difference (https://www.ebay.co.uk/itm/1080P-60FPS-HDMI-Industrial-Digital-Microscope-Camera-Kit-Sony-Sensor-IMX290-/142656675889)

Today's exchange rate puts the bundle at £441.88 with the 180x lens and stand

Bought separately it works out at £310.85 with the 120x lens (or 180x) and the same stand

Dave could you check if the top part of the lens screws off, from the lens option pictures it seems like its 2 lenses screw back to back from the 120x to the 180x.

@Spragnut
It seems the same but the seller also has another one with autofocus mentioned at 309 pounds.

Mine arrived today, I was hoping that was the case, as it certainly looks like it, but no such luck with reasonable force. Wouldln't surprise me if it's loktite, but I'm not willing to use enough force to find out.

Edit: I'm an idiot, missed the obvious set-screw holding the extension in place.

Yes, the barlow lens just screws off. So it should just be a matter of changing that.

I had bought the following HDMI camera from aliexpress, which is also 1080P, 60Hz

http://aliexpress.com/item/Professional-Digital-video-HD-1080p-high-frame-rate-HDMI-and-USB-microscope-camera-with-SONY-sensor/32464609452.html?spm=a2g0s.9042311.0.0.3da24c4dx7SIBP (http://aliexpress.com/item/Professional-Digital-video-HD-1080p-high-frame-rate-HDMI-and-USB-microscope-camera-with-SONY-sensor/32464609452.html?spm=a2g0s.9042311.0.0.3da24c4dx7SIBP)

I did attach this to a LuckyZoom microscope, but the field of view was very narrow, and the edges of the images were all washed out. I wasn't sure if it's the camera or the microscope. But Dave's camera seems to be very similar to the one I have (except mine doesn't have autofocus), so it seems the camera is OK, it must be the microscope's camera port optics ...

Here is a sample image:

The search terms for the standalone less-magnification lens would be appreciated if anyone knows them.
Try "barlow lens".

In the case of the Eakins microscope Dave has bought, there is a thread at the bottom to mount an additional barlow lens on the sample side of the objective. A 0.5x barlow lens, for example, halves the magnification and doubles the working distance, which I really like for soldering with my stereo microscope. Eakins offers compatible barlow lenses at the link below. Make sure that whatever you buy for your microscope can be mounted properly to your optics.

Must be Trump.  I just went to Aliexpress and it says 455$US.
Did you go to Aliexpress in 'Private Browsing' mode so you don't get the occasional higher fees, or, try using a VPN remote proxy connection through a different country like Canada?

I recently saw that if I use a VPN set to my destination location instead of where I live, when I book a return flight ticket from where I live to there and back, (yes, to the booking agent, it looks like I'm traveling backwards), browsing in a private window, I save 50-150$ per flight.

Now I wonder, can this be placed on the top of a Trinocular microscope, and get best of both worlds?
I'm asking because there is one in the office, and it lacks the camera.
And after a quick check, there is a 15 EUR adapter. The company we bought the scope from (who likely is a local reseller of chinese goods) charges 400 EUR for the USB version, and they dont have any HDMI options.

In fact I'm confused. There seems to be way too cheap scopes on the aliexpress.

Nice camera and setup. I'll wait until the "Dave effect" passes and get one once the temporary price increase fades away.

Of note however are the several mentions of soldering.

Dave noted a threaded collar on the lens that I assume is of standard size. That would be ideal to put a standard camera UV or neutral no loss filter that is AR coated in front to protect the lens. :)
On my setup, used regularly for SMD rework and fine soldering work, I have to clean it about once a year due to smoke coating, flux sputter and recristalisation, residues and general crap.
I can use more aggressive cleaning that I would ever dare use on the actual lens, like acetone and IPA. If I really screw up, the filter is a lot cheaper than a lens. :palm:

Another comment, for soldering work I use a LOMO dissection stereo binocular microscope. It has two separate independent optical path that give a true magnified 3D image with about 4" working distance and a wide range of magnifications. That is quite useful when working.
There is a third path, from one of the optics channels, for TV spectators or recording with a camera.

The image I see are directly under the work area which is more natural than looking at a monitor sideways while you work with the tweezers or the soldering tip and there is no lag, (however small, I never got used to that).

I say footswitch as I think unwanted focus hunting when it sees the iron could be a significant problem for working under it

I have the same thing. It's wonderful with good lighting, and utter garbage when there's not enough lighting.
The AGC is really poorly implemented. If the lighting is bad, there comes the noise and even flickering.
Also, the auto focus is not very quiet. It makes some little noise.

Nice camera and setup. I'll wait until the "Dave effect" passes and get one once the temporary price increase fades away.
What are you talking about, if you have read the thread, you will see the price dropped around 10% from these 2 Aliexpress suppliers I found here: http://www.eevblog.com/forum/blog/eevblog-1125-amazing-$500-solderinginspection-microscope!/msg1852202/#msg1852202 (http://www.eevblog.com/forum/blog/eevblog-1125-amazing-$500-solderinginspection-microscope!/msg1852202/#msg1852202)

Using the link in Daves's video...  Shipping was included, but it was well over $500 freedom bucks at the time I pulled the trigger shortly after the video.  I roll private mode on FF 100% with noscript and ad blockers, not sure if that gives me the special price.  If it does, would certainly like to know.

PLEASE READ EVERYTHING YOU ARE GETTING AND AT WHAT PRICE, INCLUDING SHIPPING!!!!!!!!!!!!!!!!  We are engineers here and this comparing products and all the features plus hidden loopholes, like forced to pay shipping for 1 part and not the others shouldn't be a problem for us.  If there is a different cost to you I don't know about, then, please let me know.

DAVES LINK, 455$, shipping included, 180x LENS, NO camera lamp, NO holder vertical table stand... Dave has a separate link for the table and for that table stand you need to pay shipping because of the stand's package size.

MY LINK #1, 400$ US, shipping included, 120x LENS instead of the closer 180x lens,  NO camera lamp, NO holder vertical table stand...

MY LINK #2, 429$ US + 59$ shipping for 488$ total, choice of 180x lens or 300x lens, INCLUDES Table Stand, INCLUDES lens mounted microscope lamp.

If you want that table with the vertical arm to hold the camera, you will always need to pay for shipping.  Dave's links do not contain a lamp for the microscope.  My 2 links are a legitimate deals.

We are engineers here, read and analyze the links I provide you with and you will get everything your want and need at the best price.  If you do not read, you will buy just the camera, then have to find a separate table holder, have the shipping for the table on 1 item, and once you buy everything a-la-carte separate, you still wont have the microscope lamp and everything will arrive at different times.

Note that a valid tradeoff is my 400$ camera with the 120x lens is a fixed zoom.
The 429$ camera + shipping has a variable zoom lens.  It's table mount holds the camera vertically.  The other more expensive table has a second horizontal sideways arm.

Thats 720p 30fps, without any mouse control only direct buttons. Probably a completely different camera.

So what is the soldering experience like under one of these compared to a typical stereo microscope like an amscope? My eyes being what they are, I need bright lights and magnification even to do through-hole soldering these days. As such when I work on a project, I sit hunched over the amscope for a bit and it becomes tedious. The Camera+monitor approach I assume would lessen the need to hunch over. Is a small screen closer to the eyes better, or is a large screen further away better? Does the autofocus try to refocus as one moves the soldering iron about?

Is adding an 0.5x or 0.35x barlow the way to go for better field / working distance / less magnification? or should one buy the 120X lens instead?

Also, for what it's worth I found AliExpress very difficult to navigate and make sense of. Even while starting out on www.aliexpress.com (http://www.aliexpress.com) in English I would occasionally get kicked over to es.aliexpress.com and switch to alternate languages. Different prices at different times for what seemed like the same or very similar items. Sometimes it took careful reading or starting at the picture to note what is different.

Thanks,
Scott

It's confusing because there are so many resellers with misleading info e.g. autofocus IMX290 cameras but if that is true they can't be made by this manufacturer (touptek).

For anyone that really wants some fun.

Go to the Ali website put the items on your watch list then switch to the mobile app put them in the cart and process as far as payment, if you switch back to the website to complete the order you still get them at the mobile price which is less than on the website.


Saved an extra £10 on the package doing it that way, so with the other discounts saved about 2/3 of the shipping.

1 x Microscope Camera
1 x Power supply(AU/EU)
1 x HDMI Cable
1 x USB Mouse
1 x 180X Zoom C-mount Lens
1 x Camera Big Stand
1 x 144 LED Ring Light

I also ordered the other two lenses which were on a 30-60 day delivery, but I was surprised to find that they had also been packed in with the camera - so that was good.
The power supply for the camera and the USB mouse were DOA, but they looked so cheap and crappy that I was going to replace them anyway, so no major problem.
There were no documents at all for any of the kit, so it took a few minutes to work out how to assemble the stand, but it's not that difficult. 

But once powered up I was impressed by the image quality and the autofocus.  The LED ring does help to reduce noise on the video.  I had always wanted a decent inspection camera and for £550 UK I pounds I think this is a bargain.

I've received mine just yesterday and I am very satisfied with it.

I threw out the metal base plate and mounted the vertical column directly to my bench. The camera is a lot more stable this way.
I managed to play the video files with VLC no problem. The camera takes a FAT32 (must be FAT32) formatted 64GB micro SD card without a problem.

I am trying to figure out a way to get more out of the firmware. It must be linux based. The mainboard is based on the Hi3516A SoC made by HiSilicon (Datasheet: http://www.hisilicon.com/-/media/Hisilicon/pdf/Surveillance_mobilecam/Hi3516AV100.pdf (http://www.hisilicon.com/-/media/Hisilicon/pdf/Surveillance_mobilecam/Hi3516AV100.pdf))
This chipset was originally designed for IP-Surveillance cameras and seems to be quite powerfull.
There is a set of three pins names J50 that are not populated, maybe they are some kind of debug output or even a linux console. I'll probe them later.
The HDMI transmitter is a SII9022ACNU made by Lattice (Datasheet: https://datasheet.ciiva.com/26836/getdatasheetpartid-368235-26836796.pdf (https://datasheet.ciiva.com/26836/getdatasheetpartid-368235-26836796.pdf))

Sure, no big deal.

It could well be an LCD connector.
It might also be an alternative connector for the sensor when using a different enclosure.

I am trying to figure out a way to get more out of the firmware. It must be linux based. The mainboard is based on the Hi3516A SoC made by
Just find a serial port, J50 maybe. I have the original Hisilicon SDK somewhere.

Edited to clarify some things:
Even though is easy to find new SDK versions on the Internet, additional drivers will be needed to get something functional.
For example, to my knowledge, even the latest versions come without a driver for the IMX290/291.

Probably you can do it via USB and SD card too, for IP cameras, LAN is the easy way.
IP cameras based on Hi3516A are easy to mod, and a lot more cheap.  ;)
The problem is the delay via LAN, and the zoom/auto focus, they require totally different lenses.

For example: https://hupuu.com/camera/ipcb-3516as291-d29-et9-1080p-50fps-1-2.8-2mp-sony-imx291-hi3516a-ip-starlight-security-cctv?sku=CBF-D29 (https://hupuu.com/camera/ipcb-3516as291-d29-et9-1080p-50fps-1-2.8-2mp-sony-imx291-hi3516a-ip-starlight-security-cctv?sku=CBF-D29)

As an alternative, has anyone tried a microscope setup using a digital SLR with HDMI out?
e.g. Nikon D3400 (with 60fps HDMI) + C-mount adapter + lens
Costs look comparable on ebay, with the advantage that you also have a SLR.

Ahh, maybe you don't get auto focus when the SLR mirror is up for 'liveview video'.

Ahh, maybe you don't get auto focus when the SLR mirror is up for 'liveview video'.

I've shot still images and video on a trinocular amscope with my Canon t6i (and t2i before that). I've not tried viewing the HDMI out while recording, but the recorded image when I play it back on my PC is great, though the field of view is significantly less than what I see through the eyepiece. What this doesn't achieve is any sort of autofocus. The focusing mechanism is inside the camera lens, and that lens is removed and replaced with the microscope adapter. You can set the trinocular microscope up so that the camera is in focus when the eyepieces are in focus, but still if you tilt the board or you zoom the microscope, you have to fuss with the focus. IMO autofocus is the biggest advantage to the Eakins setup in Dave's video.

I pulled the trigger Friday evening and ordered the Eakins setup. I picked the package that includes the stand and the small LCD monitor (another small LCD monitor will always come in handy). I also purchased an 0.35 barlow that I'm going to try with it to see how much it improves the field of view. I've also ordered a c-mount adapter so I can try mounting the Eakins directly to my amscope and compare that to the lens that ships with the Eakins. The Eakins hasn't shipped yet, but I'll respond with my impressions when it eventually arrives.

Ali Express triggered fraud alerts on both the credit cards I tried to use, led to some grief trying to place the order. My order is currently in "being verified" state. I guess the lack of trust between Visa and AliExpress is mutual.

I was looking forward to trying one of these out today, but for some reason the package that was supposed to contain the bits I ordered got delivered to someone in France this morning and not the UK.

With a bit of luck it was only an error in the tracking number and it is still on route but I am not holding out much hope as the AliExpress tracking shows it as enroute to the UK.


I have sent them a message to ask what is going on so I will have to wait and suspect it will now be another week at least before I get one to play with.

I've had a play using a bodged together dslr+HDMI macro rig as a possible soldering setup. Latency was OK with my cameras (EOS M and M5) but there were other problems:
- You have to muck about to try and get a reasonable aperture (wide open does not give enough depth of field). Aperture setting will not necessarily apply in live-view mode, only when you actually take a pic.
- video output was stuck at 720p/1080i depending on the camera (and that's after pissing about with the monitor's EDID EEPROM to add specific resolutions that the cameras liked, otherwise they spat out SD)
- the output is not native sensor resolution either (they do pixel skipping and stuff), so you're not getting the best out of the camera

I'm not completely giving up on doing things this way, but it's clearly easier going the aliexpress camera route!

Nice camera and setup. I'll wait until the "Dave effect" passes and get one once the temporary price increase fades away.
What are you talking about, if you have read the thread, you will see the price dropped around 10% from these 2 Aliexpress suppliers I found here: http://www.eevblog.com/forum/blog/eevblog-1125-amazing-$500-solderinginspection-microscope!/msg1852202/#msg1852202 (http://www.eevblog.com/forum/blog/eevblog-1125-amazing-$500-solderinginspection-microscope!/msg1852202/#msg1852202)

Using the link in Daves's video...  Shipping was included, but it was well over $500 freedom bucks at the time I pulled the trigger shortly after the video.  I roll private mode on FF 100% with noscript and ad blockers, not sure if that gives me the special price.  If it does, would certainly like to know.

PLEASE READ EVERYTHING YOU ARE GETTING AND AT WHAT PRICE, INCLUDING SHIPPING!!!!!!!!!!!!!!!!  We are engineers here and this comparing products and all the features plus hidden loopholes, like forced to pay shipping for 1 part and not the others shouldn't be a problem for us.  If there is a different cost to you I don't know about, then, please let me know.

DAVES LINK, 455$, shipping included, 180x LENS, NO camera lamp, NO holder vertical table stand... Dave has a separate link for the table and for that table stand you need to pay shipping because of the stand's package size.

MY LINK #1, 400$ US, shipping included, 120x LENS instead of the closer 180x lens,  NO camera lamp, NO holder vertical table stand...

MY LINK #2, 429$ US + 59$ shipping for 488$ total, choice of 180x lens or 300x lens, INCLUDES Table Stand, INCLUDES lens mounted microscope lamp.

If you want that table with the vertical arm to hold the camera, you will always need to pay for shipping.  Dave's links do not contain a lamp for the microscope.  My 2 links are a legitimate deals.

We are engineers here, read and analyze the links I provide you with and you will get everything your want and need at the best price.  If you do not read, you will buy just the camera, then have to find a separate table holder, have the shipping for the table on 1 item, and once you buy everything a-la-carte separate, you still wont have the microscope lamp and everything will arrive at different times.

Well Mr. Engineer, long story short...

The original order took more than 7 days to even ship.  I requested they cancel the order at that point.  Two days later the seller responded and in all fairness refunded claiming Chinese holiday.  After that refund went though, I hit your "With stand and circular LED lamp for 429$" link.  I didn't catch this is the same seller.  Felt a bit douchie re-ordering a better priced package after canceling.  I paid for DHL and sure enough it shipped withing 48hrs and came in short order.

Package as received, is missing the lens totally and I have 50% of the base.  I have the horizontal bar and hardware only.  Nothing to adapt the missing lens to it let alone the base and vertical support.  Looking at what I have, the base is prob worth the price but total crap to my amscope setup I have now.  Amscope vertical and horizontal supports are solid metal, this horizontal support is hollow and full of rust.  Aka, take off the end cap off to assemble and 1-2 grams of rust fall out.

At this point, I'll have to quote AvE.  Time to piss with the cock you got.

Not wasting my time with the seller anymore.  They refunded me in full (though by paypal so I incurred a fee from those parasites) once already.  Its aliexpress and just another layer of hell deeper than ebay.  Sometimes you win, sometimes you don't.

The camera alone is pretty awesome for the price.  I mainly though it would be a perfect replacement to my current amscope camera.  Using it as advertised would have been ok, but doesn't really fit my lab.  I have a 4' hood for soldering and there isn't room for a stereo microscope and this as a standalone setup.

I have it on my amscope with a 0.5x adapter.  Mag is still too high for what's ideal, but its usable and a 5x improvement from the cam I had.  Find the right optics and adapters this thing is still gold for the price.

If anyone wants a Amscope MC300 camera, its yours if you cover shipping.  PM me.  This cam needs lots of light but takes pretty good images.  I use it with amscope's brightest led ring and its fine until I'm working a the max mag level.  Biggest complaint...its never in focus with the eye piece so I have to piss around before taking pics.  Not the end of the world but annoying.

Received mine today, ordered boom stand + camera + base + LCD monitor + ring light. Also ordered an 0.35 barlow that screws onto the bottom. Everything was there, though I was worried for a bit things were missing -- some parts to the base were packaged inside the box the held the LCD monitor.

The 12V 1A wall-wart included for the LCD monitor is insufficient to power the monitor. It just sort of blinks on and off when in HDMI mode. Tried my own 12V 1.5A wall wart and the monitor worked fine. What the hell? Whoever put these packages together didn't check to see if the wall-wart can power the LCD? It's not like I don't have plenty of wall-warts, but still....

The boom stand is capable but greatly inferior to the boom stand on my amscope trinocular microscope. The tube diameters are smaller. The metal feels thinner. The base seems to weight less. Took me a little while to figure out how to put it together.

The mouse locked up once and the pointer wouldn't move. Not sure if this was a mouse problem or a camera problem.

The autofocus tends to hunt back and forth a lot more than I'd like. To make this usable, I'm definitely going to need to find a way to easily toggle autofocus on and off. I've been thinking a "Pi Zero W" in USB gadget mode emulating a mouse might do it. It looks like one could reliably home the mouse cursor, then move a preprogrammed distance to hit the autofocus and manual focus buttons.

Tried the camera mounted directly to a C-Mount adapter and placed on the photoport of my Amscope trinocular microscope. Working distance in this configuration was crazy small and unusable, like an inch or two. Maybe I need to include some additional optical element between the photoport and camera? I'm not an optics guy, I just stick things together and assume they'll work.

The 0.35 Barlow on the supplied lens (not on my Amscope) makes the working distance crazy big. Seems approximately 8" on zoom-out, and 14" (hard to say, I had to pick the thing up off the stand, and hold it in my hand) on zoom-in. This would probably be useful soldering at the lowest magnification, but neuters most of the zoom capability. Maybe I need to play with it a bit more, and get the distance set to the sweet spot to maximize the zoom capability with the barlow attached.

Seller refunded in paypal, I purchased with CC.  To purchase in paypal on alihell I got dinged a ~$20 fee for the new order.

So I paid extra for DHL and hit with the paypal adder, the total came out to a few bucks more than my initial order. 

I wanted the camera and got it.  Its great, the rest of the addons are trash IMO.  Bare in mind I don't have the lens.

Love to give all the part #s, but I assume you know as well amscope and the little misc pieces are a $hit show.  I have the original packing list on my setup, will dig up.  From what I can gather I have the camera port and its all working down to that.  That said, I doubt there is part #s on any of the adapters.  I sure can't find replacements on their site.  Would love to switch out my .5x for .25x or lower.

The cam as is, does auto focus on my setup.  Its far better than what I had, but certainly not perfect.  Mag is to high on the low end, but very usable above my min needs.  Can't complain with the quality of the cam @ whatever I paid, its awesome.

Min mag with my setup as captured via SD with the cam direct.

Putting a tape measure in the field of view its roughly 3/4" x 3/8"  These images are far better than I get with the amscope cam I had and still a fraction of what I get in the eyepiece.

I canceled order in ali, then the seller had to approve.  They finally did two days later and refunded via paypal.  Which surprise, ali passes paypal fees to the buyer.  So on the reorder using my refund, ~$20 got sucked into the ether.

Yeah, I even went so far as to email them, but received an unhelpful response. Just trying to figure out what I own now, and the dimensions and such of the photo port threads is hard enough. They seem to have sold several different microscopes with several different types of photo ports. I've owned the thing for 8 years and it's been a great tool at an incredibly good price, so I suppose I can't complain too much.

Thanks for the pictures.

Whether or not they'll thread onto my amscope, I have less than no idea. If they do thread on (or if I bodge it together), then I have no idea whether it will yield a usable picture.

I should know in about a month... (Kinda wish I'd have chosen DHL, but I was in a cheap mood last night)

Working distance in this configuration was crazy small and unusable, like an inch or two.

Measured what I have in my setup.  So bench to scope is 5".  I can turn a ~5" board near vertical and the AF with the mag @ min, it will focus on anything from the bench to about ~3.5" above without ever changing the microscope focus.  That alone is a hell of an upgrade from what I had.  It goes to hell when your working on the edges of what the AF can deal with.  If I have the eye pieces in focus, the cam seems in its happy spot.  At least if I move the scope within ~50% of its mag range.  Moving from min to max, I need to adjust the cam height in the adapters so its happy again or deal with endless hunting.  I never really use my setup at the max.

Pi to fake the mouse should certainly work I would think.  Find if I'm mindful of the AF, just keep the window in areas of the same height its not too annoying.  A foot pedal would be ideal.

Since that boot lists the SoC, here's the short form datasheet (http://www.hisilicon.com/-/media/Hisilicon/pdf/Surveillance_mobilecam/Hi3516AV100.pdf).

From a press release:
Quote
Hisilicon released Hi3516A SoC (System on Chip) which is based on latest H.265/HEVC standard for high definition IP cameras. The Hi3516A adopted Hisilicon H.265/HEVC algorithm, greatly improved image quality to eliminate motion blur, meanwhile reduced 50% bit-rate without compromising the image quality.

Furthermore, Hi3516A utilizes ARM Cortex-A architect, integrated with Hisilicon's 2nd generation intelligent video analysis unit (IVE2.0) to support license plate recognition, perimeter protection, facial recognition, zone alarm...etc more than 40 different kinds of smart video analysis applications.

Through multi-frame combination WDR and Hisilicon's third generation 3D noise reduction technology, although security cameras work in challenge-able lighting condition, it can still provide excellent images. Hi3516A support up to 5 megapixel real time video encoding, utilizing Hisilicon's advanced network transmission technology, the video latency can be achieved below 100ms.

I've had some success connecting an Arduino Pro Micro to the USB port and using it to programmatically turn autofocus on and off by emulating mouse movements and clicks. Eventually I'll try to rig up something nice with some buttons, LEDs, and a jack for a foot switch. A 3-pack of Arduino Pro Micro clones from Amazon was only about twenty bucks.

Although it would be nicer to exploit the serial header that's been discovered, if that turns out to be impractical, this seems like a useful technique to fall back to.

I received the microscope adapters (https://www.aliexpress.com/item/Low-Price-0-5X-C-mount-Lens-Adapter-1-2-CTV-Adapter-For-SZMTV1-2-Trinocular/32814332968.html (https://www.aliexpress.com/item/Low-Price-0-5X-C-mount-Lens-Adapter-1-2-CTV-Adapter-For-SZMTV1-2-Trinocular/32814332968.html)) that I ordered to hook this up to my trinocular.

* The thread actually fit my amscope (I had my doubts)
* It produced a mostly-usable image (I had my doubts)
* It's very compact
* It's not parfocal with the eyepieces, not even remotely close
* I lost half the working distance of the Amscope
* Autofocus suffers from significant vignetting as one zooms in.

I spoke too soon! I just played around with it fiddling with the adjustment ring on the adapter. I can get it parfocal with the eyepiece, and I can get the working distance equal to that of the eyepiece! I still don't get much usable zoom out of the Amscope though.

Some pictures are attached.

What microscope head are you using?

I got what looks like the same lens, but there is no way to adapt it the my head.  I have a handful of lenses coming that should work with my setup coming.  Max width I can get with my setup and this 1x lens https://www.amscope.com/accessories/adapter/1x-c-mount-camera-adapter-for-nikon-microscopes-1.html (https://www.amscope.com/accessories/adapter/1x-c-mount-camera-adapter-for-nikon-microscopes-1.html) is 1.5CM,

Once I get this cam where I want, I'm upgrading to a real trinok head where all ports have light.  With Amscope, the closest match to what I have now is the SM745TP which still has the same 23mm photo port interface, you must have some threaded port.

The capture problem I have to assume isn't a big hurdle.  It works fine with HDMI monitors I tossed at it, so there must be a capture device that's compatible.

The only reference I have is "3.5X-45X Trinocular Stereo Zoom Microscope on Single Arm Boom      SM-3TX             1  379.00". Typical of Amscope, it's not all that easy to figure out exactly what I have. From what I gathered on Aliexpress, there were two styles of adapters for two different generations of Amscopes. There's the "old" threaded style like mine, and there's a newer bayonet style.

I also have a 0.5X barlow attached to the Amscope, screwed into the very bottom.

A real trinocular head that was live to all three ports all the time would be nice.

Hello
I'm looking to get one of those cameras for my AmScope trinocular microscope, but I have a question: can it output a square 1:1 image using the whole sensor? - my current camera outputs 16:9 and crops the top and bottom.

And here's a handy thing for getting the camera's view similar to that you see through the eye pieces: Focus adjustable 0.35X C mount adapter for New Type of Amscope, the one with the flange rather than screw mount. https://www.aliexpress.com/item/0-35X-focus-adjustable-C-mount-adapter-for-New-type-of-Amscope-s-Trinocular-Stereo-microscope/32830788378.html (https://www.aliexpress.com/item/0-35X-focus-adjustable-C-mount-adapter-for-New-type-of-Amscope-s-Trinocular-Stereo-microscope/32830788378.html)  For my camera I needed to add a 5mm C-mount extension tube to get the focal distance down to normal. There is a little bit of barrel distortion, but its still much better than the slide tube that comes with the microscope. I first saw it being used by Paul Daniels (not the magician) on his iPhone repair YouTube channel.

On the subject of camera lenses - that is a lens between the camera and the third port. The image you see depends on the sensor size in the camera. A small sensor (around half inch) crops and magnifies the image - so you need a reduction lens, like above. But with an APS-C or Full Frame sensor you need a magnification lens as otherwise you get to see the barrel of the connecting tube.

So what is the soldering experience like under one of these compared to a typical stereo microscope like an amscope? My eyes being what they are, I need bright lights and magnification even to do through-hole soldering these days. As such when I work on a project, I sit hunched over the amscope for a bit and it becomes tedious. The Camera+monitor approach I assume would lessen the need to hunch over. Is a small screen closer to the eyes better, or is a large screen further away better? Does the autofocus try to refocus as one moves the soldering iron about?

I'd be interested in hearing about how useful this is for soldering too.  I'm getting to the point where I'm in the same boat and am in need for a magnifying aid.  How's the display lag, and is there an issue with autofocus jumping around when moving an iron (or worse, braid) under the scope?

Anyone know how the 120x stacks up against the 180x?

Also, I went poking around the Eakins Aliexpress store and it appears they have 4 variants of the camera using the IMX290 sensor.  In addition to the one Dave reviewed, there's a near identical version without the microsd card slot, and then there's this thing (https://www.aliexpress.com/store/product/AF-Autofocus-IMX290-Full-HD-1080P-60FP-Auto-Focus-Industrial-Video-Microscope-Camera-large-Visual-Field/3200040_32949998514.html?spm=2114.12010615.8148356.30.3b42178chl6sKe).  It also comes with or without the microsd card slot, and appears to have the optics built in.  But what's interesting is the version with microsd has an I/O connector.

They also have two different stand versions.  One with a boom and one without.  That's a lot of options there.

Hard to see any lag to the display.  AF and soldering would be a PITA without a foot pedal to lock it IMO.

Personally I don't know I could go from stereo vision to a display without a load of practice and really wanting to.  That said, I don't solder 8hrs a day.

Got this lens which works with the newer Amscope camera port. https://www.ebay.com/itm/0-3X-C-mount-Microscope-Adapter-for-CCD-Cmos-Camera-Digital-Eyepiece-Relay-Lens/273459117292?hash=item3fab6efcec:m:mBPSS1sgOSdJT09Djl9ieIg:rk:1:pf:1&frcectupt=true (https://www.ebay.com/itm/0-3X-C-mount-Microscope-Adapter-for-CCD-Cmos-Camera-Digital-Eyepiece-Relay-Lens/273459117292?hash=item3fab6efcec:m:mBPSS1sgOSdJT09Djl9ieIg:rk:1:pf:1&frcectupt=true)

The lens and its 0.4x brother are crap quality, focus is off on just one side and there seems to be bubbles in the glass that the AF will sometime focus on.  That said 0.3x seems to give me an acceptable magnification range would like even less.  Things are parafocal with the eyepieces.  Getting closer... Will have to try Kazzle's suggestion.

There's a little snippet of soldering in my video here, around 12 minutes in:

 http://www.youtube.com/watch?v=2VSm2PZRRCs (http://www.youtube.com/watch?v=2VSm2PZRRCs)

All I soldered was a couple of 0.100" headers. There are two things that struck me: 1) lack of depth perception makes soldering a little more difficult, and 2) the natural human inclination is to look toward what you're working on rather than looking at a screen on the wall. I think with practice you could adapt to both of these differences. I highly recommend getting one of the barlow lenses for it to reduce the magnification and increase the working distance / field of view.

My gut feeling is that my preferred tool for soldering is going to remain my Amscope microscope, and my tool for inspection will shift toward the Eakins (mounted on the Amscope's trinocular photo port).

I have a solution for AF/MF toggle (including a foot pedal). Going to do up a video on that this weekend.

You would have to have a capture device device right?

I jumped on the Eakins bandwagon a few weeks ago.  After getting the run around for 2 weeks then it 'accidentally' getting shipped SF Express instead of DHL adding another 2 weeks, I finally received my very own copy.  I went with just the head w/180x lens, the 300x lens, a ring light, and the set of 3 Barlow lenses (.35, .5, 2x).  My bench shelves are made out of 8020 extrusions so I used that to make up a quick overarm to hold the camera.  It keeps the bench clear and allows me to raise the scope over 1m off the bench :-+.  In addition, I 3D printed an adapter to stack the .5x lens on the bottom of the .35x Barlow.  With that combination and my camera at the ceiling I can get a 130mm (5") FOV, although zoom is limited by the distance between the 2 stacked lenses.  For my needs, the 180x lens with the .35x Barlow provide an adequate range for routine PCB stuff.

The UI is just painful to use.  The mouse is way too sensitive and I had an extremely difficult time keeping it on the focus scroll bar while using the scroll wheel.  I had the same idea as smbaker to use Pro Micro's due to their small size and ability to act a mouse.  I used a rotary encoder for changing values in the scroll bars, a BCD coded switch to select the various functions, 3 pb switches to act a soft keys, and of course the ubiquitous 16x2 LCD for the display.  I had  a difficult time getting things to work at first.  I finally figured out that the camera is very slow and was simply missing events if I sent them at full speed.  Every mouse move or click event has a delay between it and the next event.  It still misses things now and then and gets out of sync, but selecting something else usually gets it in line.  I have the majority of the items on the camera menu implemented and most of it works well despite the clunky way I'm going about it.  I'm waiting on some prototyping PCBs to show up so I can get it off the breadboard and into a case.

I finished building and trying out mine today. I too had to play with delays a bit to make the whole thing reliable, but at this point it seems to be pretty solid. My UI consists of 5 buttons, an LED, and an optional foot pedal. I did briefly consider adding a display (I have a pinout for an e-paper display; I seem to be into e-paper these days!) but couldn't come up with a good motivating reason. Here's my video:

Very impressed @smbaker
I think I have a Digispark AtTiny85 lying about in a junk box somewhere.
It is likely the only pre-built MCU module I have that supports USB directly.
I think it only has 4 I/O when USB is in use, so I will have to settle for AutoManual, FocusNow, Picture and an LED.
Looks like it might support emulating a mouse.

I've finally had the time to probe around J50.

It is indeed a serial port, running at 3.3V and a baudrate of 115200.

Now comes the best part....

The serial port leads into a ROOT linux console. No password needed.

I'll try to dump the files by using a flash drive. Stay tuned.

Below is the bootloader output and the response when running "whoami":

I've also attached the pinout of the connector.

I connected to the serial console, and managed to copy what appears to be the main program, and a couple other files also in the /opt/ directory.  If anyone knows a good method to dump the entire flash, I will gladly do so and post any findings here.

I'm working on setting up a USB->ethernet dongle, so I can connect with SSH.

Can anyone find a full datasheet for the Hi3516A processor?  It looks like there's ethernet onboard.

Thanks so much this project idea. This was so awesome, it's on my short list to apply to my microscope as well.

Quick question for other owners of the Eakins microscope. Is anyone using the supplied small LCD monitor that came with the kit?
If so, do you have any pictures for how you've mounted it to the stand? I can't for the life of me work out how it mounts on the black horizontal bar with holes in it.

The monitor comes with a a massive sticker and wall mount to attach it to a flat vertical surface. How is it supposed to connect to the supplied stand?

I'm using the monitor and stand.  I'm not using the sticker or wall mount bracket at all.  I'll try to remember to take pictures tomorrow.

I discovered something interesting when looking at strings in the "myTest_8.17" executable:
www.seekscope.com (http://www.seekscope.com)

Just a random URL which leads to an awful website for a microscope company.  Searching their name leads to a slightly better website:
http://isscope.com/ (http://isscope.com/)

I think we're getting closer to finding the OEM.

Awesome! The closest I've got to getting it attached it rotating the whole so they are vertical and using the too long bolt to thread into the bottom of the monitor. But seems flimsy as all get out. :palm:

Sorry, I didn't remember to take pictures of the setup.  I'll try Monday.

More research reveals two things: the Hi3516A processor requires an extra chip for ethernet, and the filesystem is currently not persistent.  There must be some special way to write to the flash, and I'm guessing the entire filesystem as presented is actually in RAM.

Yep, sorry, I keep forgetting.  Here are the pictures of my setup.

The little monitor does not hold securely at all, and keeps falling over.  I'll have to make a better bracket at some point.

The working range on this microscope is amazing.  I had to flip a bracket around just to get more height.  I'll probably attach it to the shelf above.

Good news, everyone!

Just received this particular HDMI capture adapter from ali, and it happily recognizes the scope's HDMI output:

https://www.aliexpress.com/item/USB3-0-1080P-60FPS-HDMI-Live-Streaming-Dongle-USB-3-0-Game-Video-Capture-Box-for/32822156604.html (https://www.aliexpress.com/item/USB3-0-1080P-60FPS-HDMI-Live-Streaming-Dongle-USB-3-0-Game-Video-Capture-Box-for/32822156604.html)
It lists for $85 now, but was $65 on 11.11 when I bought it. There are lot of similarly looking ones on ali, so probably will be able to find a cheaper deal.

Proof is attached: my large screen 4K TV now shows both desktop stuff and the camera output at the same time. No need to switch HDMI inputs.

Thanks for that - I didn't think to try the main bolt with the nut that was on the wall sticker mount. All good now - I'll work out how to get the monitor to stay where I want to. as you said, not exactly sturdy, but it will do for the moment.  :-+

Proof is attached: my large screen 4K TV now shows both desktop stuff and the camera output at the same time. No need to switch HDMI inputs.

Good to know.  Does this work with OBS?

Got this today to try

Tested it with Ruko and the pass thru wouldn't work with 720p, but the passthur did work with the camera.  Under win10 it came in as a camera.  Couldn't get it to work with VLC or OBS, so its going back.  Have a Magewell USB Capture HDMI Plus coming now to try with it.

Doh...   |O  I'm assuming the camera would have worked with the first capture device.  Someone seems to have had their W10 privacy settings set to disable camera access...which go figure is how these devices show up.

That issue aside, it works perfectly well with the Magewell USB Capture+.

Attached is the output from the Magewell capture utility that gives all the details of the HDMI stream.  Maybe that will be helpful to someone when trying to figure out what will be compatible with it.

Good news, everyone!

Just received this particular HDMI capture adapter from ali, and it happily recognizes the scope's HDMI output:

I tried the OBS, added this ezcap as a capture source and it was showing the live microscope feed in the OBS UI. I don't use OBS, so not sure what else should I try there.

My main reason of using the capture card is to have the screen showing both microscope live camera picture and the other stuff I'm working on, like datasheets, code and schematics - having it all on one large screen.

BTW, I cracked this Ezcap open, and here is what's inside - picture attached. Two either custom or relabeled chips, standard HDMI input and output chips. Two serial EEPROMs - one large and one small (config?). And four channels of DC-DC. There is nothing on the other side of the board.
There are two groups of unsoldered pin headers or test points - some of them might be UART in/out. I may later try to poke them with oscilloscope to find out if there is an UART TX, and if so will see what kind of output it dumps there...

I got in the "bundle" and barlow lenses.   Seems to work well. (note that they pack some stuff in the monitor box... I first thought that they didn't ship the barlows)

Circles are a bit out of round on the 10" HDMI monitor.   I couldn't drive DVI displays with HDMI->DVI converters.

The 180X lens' largest field-of-view with the 0.35 barlow is around 2x1".   Stacking a 0.5 and 0.35 barlow gives a 2.5" wide FOV. 

Raising the camera up 2" from what the stand allows gives a 3" wide FOV.   I'd like to be able to get even wider.  I will probably try the 120mm lens and maybe stack a couple of 0.35 barlows...

Ideally, I'd like to be able to get a 6x4" FOV when needed.   That would probably require extending the stand  tube (it is internally threaded at the top with the same external thread as the base so one could probably screw two tubes together).  Does anybody know where to buy extra or longer stand tubes (without buying and scavenging a second stand)?

SMBAKER, are you going to publish the code for your nifty mouse emulator thingy?

I measured the power required by the camera.  It starts at around 0.2A, but once it finished booting up the power increased to 0.7 to 0.8A.   The supplied wall wart outputs 5.3V.   I don't trust no-name wall warts so I am now using a genuine Apple 2.4A one.

I don't have any spare monitors with HDMI inputs, so I tried using (4 different) HDMI->DVI converters with the camera... no joy.   This could be related to the issues Dave had with HDMI capture devices.

Does anybody know of a HDMI->DVI converter that works with the Eakins?

As an alternative, has anyone tried a microscope setup using a digital SLR with HDMI out?
e.g. Nikon D3400 (with 60fps HDMI) + C-mount adapter + lens
Costs look comparable on ebay, with the advantage that you also have a SLR.

Ahh, maybe you don't get auto focus when the SLR mirror is up for 'liveview video'.

I currently use a JVC camcorder which has an integrated 40x optical zoom, to which I have added a front lens to get a reasonable working distance (15-20cm). I use the HDMI output and get very low latency (not noticeable). There is no way of using a C-mount lens with it, optics is not removable (it's an entry-level camcorder, but picture quality is fine.) The max magnification factor I get with a 14" monitor is approx. 40x (eg. 0.5mm pin pitch is close to 20mm on screen.)

The autofocus works reasonably well even with the added lens (seems a bit slower though, and it occasionally gets confused - usually moving the part around in the field of view gets it to focus again). I can always set it to manual focus if it bothers me.

With a DSLR, you'd have to try. Don't know if it'd work as well as a camcorder. One thing to consider is the mounting of the DSLR itself - they are usually a bit heavy so you need a sturdy mount.
With my camcorder I currently use a Manfrotto articulated arm, and it's not ideal. It tends to shake a little when just tapping on the desk, hardly noticeable at low magnification but it's a bit annoying at the largest magnification.

I recently ordered a couple of C-mount lenses, one up to 10x for larger fov and the other to 720x and a set of barlow lenses. Also ordered a C-mount camera module with HDMI output (unfortunately not with the autofocus, but with a Panasonic 21MP sensor). I'll see what I get with that. One thing that would be nice would be a motorized stand of some sort.
