content: I ordered one from an eBay seller a few weeks back afterthe previous thread, 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.

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:

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.https://www.aliexpress.com/store/product/0-5X-2-0X-0-35X-Barlow-Auxiliary-Objective-Glass-Lens-For-XDC-10A-180X-300X/3200040_32845571497.html﻿

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.

content: 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.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).

Dave has a separate link for the table and for that table stand youneed to payshipping because of the stand's package size.MY LINK #1, 400$ US,shipping included, 120x LENS instead of the closer 180x lens,NOcamera lamp,NOholder vertical table stand...MY LINK #2, 429$ US + 59$ shipping for 488$ total, choice of 180x lens or 300x lens,INCLUDESTable Stand,INCLUDESlens 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.

content: 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 onwww.aliexpress.comin 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

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.

content: 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)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)I've attached a couple of photos of my setup, the main PCB and a few sample shots to this post.Images:Main PCBTop:https://s3.eu-central-1.amazonaws.com/cdn.hog-duske.com/manual/microscope-camera-2018-10/images/board-main_top.jpgBottom:https://s3.eu-central-1.amazonaws.com/cdn.hog-duske.com/manual/microscope-camera-2018-10/images/board-main_bottom.jpgMotor and sensor assemblyWhole assembly:https://s3.eu-central-1.amazonaws.com/cdn.hog-duske.com/manual/microscope-camera-2018-10/images/assembly-motor_sensor.JPGSensor board inside the assembly:https://s3.eu-central-1.amazonaws.com/cdn.hog-duske.com/manual/microscope-camera-2018-10/images/board-sensor.JPGMy setupFull setup:https://s3.eu-central-1.amazonaws.com/cdn.hog-duske.com/manual/microscope-camera-2018-10/images/setup-full.JPGMounting arm:https://s3.eu-central-1.amazonaws.com/cdn.hog-duske.com/manual/microscope-camera-2018-10/images/setup-mounting_arm.JPGSample imagesLowest magnification:https://s3.eu-central-1.amazonaws.com/cdn.hog-duske.com/manual/microscope-camera-2018-10/images/samples-lowest_mag.jpgHighest magnification:https://s3.eu-central-1.amazonaws.com/cdn.hog-duske.com/manual/microscope-camera-2018-10/images/samples-highest_mag.jpgThe samples were captured directly on to the SD card using the camera.

content: Quote from: voltsandjolts on October 13, 2018, 07:36:34 pmI'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.Scott

content: Quote from: mikeselectricstuff on October 13, 2018, 07:53:23 pmI'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 cameraI'm not completely giving up on doing things this way, but it's clearly easier going the aliexpress camera route!

content: Quote from: BrianHG on September 27, 2018, 03:37:33 amWell 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.

content: 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.Scott

content: Quote from: smbaker on October 19, 2018, 06:01:49 amMeasured 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.

content: 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.Scott

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.

content: 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 lenshttps://www.amscope.com/accessories/adapter/1x-c-mount-camera-adapter-for-nikon-microscopes-1.htmlis 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.

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.Scott

content: HelloI'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.htmlFor 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.Karl.

content: Quote from: smbaker on October 02, 2018, 04:19:27 pmI'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 have4variants 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'sthis thing. 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.

content: Quote from: knotlogic on November 08, 2018, 12:13:01 pmHard 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=trueThe 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.

content: Quote from: knotlogic on November 08, 2018, 12:13:01 pmThere's a little snippet of soldering in my video here, around 12 minutes in: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.

content: 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.

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'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.

content: 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.

content: 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.htmlIt 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.

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.

content: Quote from: orion242 on December 09, 2018, 09:46:52 pmI 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...

content: 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?

content: Quote from: voltsandjolts on October 13, 2018, 07:36:34 pmI 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.

content: I'm kind of late to the party, but I bought one of these microscopes on AliExpress when I saw the EEVblog video. I've been using it for the past few months, and I'm very, very happy with it. I also got 0.35x and 0.5x Barlow lenses for it. I find myself using the 0.35x lens, and it works great. It gives me a good working distance of about 5 inches and it's not zoomed in too far (although I can zoom in further if I want). There is no discernible lag to the HDMI output. It has immensely improved my ability to do fine pitch soldering. I find myself using the "click to focus" feature, so that it isn't constantly refocusing when I'm soldering.Minor complaints:There is no lens cap for the Barlow lenses, but I'm sure I can find one somewhere.Video recording to SD card works okay, but the raw .h264 video format is kind of goofy and there is a 2 GB file size limit because of FAT32If you try to record past 2 GB, the file size just gets truncated with no warning or error given to you. So if you're recording a long video, you just have to stop and restart it occasionally. I find that the .h264 video plays kind of jerky in VLC, but if I convert it to .mp4 with ffmpeg first, it plays a lot better. I *think* it's recording at 30 fps, but I'm not 100% sure. The timestamps seemed to match up with 30 fps.Here is the command I use to convert the .h264 videos to .mp4 for better compatibility (doesn't do any transcoding, which is great):Code:ffmpeg -vcodec h264 -framerate 30 -i 5-34-41.h264 -vcodec copy -acodec copy 5-34-41.mp4Sample video I recorded (using record to SD feature) of drag soldering some TSOP chips with the 0.35x barlow lens attached:https://youtu.be/5Jvc-VzCfpY

content: Quote from: smbaker on November 09, 2018, 05:11:06 amI tried it with my microscope, and I think the lack of depth perception makes soldering A LOT MORE difficult. I removed a 0402 SMD resistor from a board and tried to replace it with a piece of wire, and it was very hard for me to ensure that the piece of wire was touching both pads so that I can solder them. And then there was also the difficulty in judging how close my iron tip is to the wire. It was VERY HARD. I switched to my optical stereo microscope and it was so much easier and I finished the job in no time!So I think for repair work, a stereoscopic microscope with depth perception is a MUST. Bur for inspection of a board, this microscope will be fine.I think here is what the ideal setup would look like. Two of these microscopes side by side, and display glasses with a separate screen for each eye, and two HDMI inputsProblem is, I can't find any display glasses that have separate HDMI inputs for each screen. Sure, there are truck loads of VR glasses, but those are all single HDMI input, with some kind of 3D support, which is totally unrelated to what I want it to do. And searching for such glasses is very hard in google. Most matches are completely unrelated stuff like normal glasses, window glasses, other glasses. Or HDMI displays, monitors, other displays grrr.

content: Whoa, this mic(roscope) is pretty expensive.. Dave, you`ve done great with the microscope review, I was simply searching on youtube for "usb microscope review" and was presented with your video as a suggestion... However, $500 breaks the bank for me... Any cheaper alternative? I had found some "electronic focus" microscope (which I guess is user-controlled focus) on AliExpress for around $84, yet if anyone could recommend something similar without the auto-focus feature (that one breaks the wallet), I would gladly appreciate the advice and consider the thing...Here are the cameras I found:1. 84-usd one, I suppose I also need a C-mount (whatever this mount is) lens assembly, although I see none at this seller.. was hoping to find something compatible on seller`s page, yet it should be C-mount.. what should be a magnification for regular circuitry?https://www.aliexpress.com/item/Remote-Control-SONY-imx323-sensor-HD-1080P-HDMI-C-Mount-Digital-Video-industrial-microscope-camera-for/32978144150.html2. some all-in-one camera, manual focus? doesn`t state anything.. $105 with 180x or 300x, $70 with 180x objective.. these numbers don`t tell me much, I am still watching videos to get some idea on this.. navigating forums etc..So I`m fixing car keys and other stuff for now, as part of my hobby... Started fixing for my friends (I simply hate paying the stealership big bucks, didn`t want my friends to pay neither..), now I get about 1 key per week, sometimes less.. fixing is about $20~40 per key, parts included, so $500 for a microscope is out of discussion.. Currently I am doing this besides my full-time job (software engineer / industrial automation / c++) which is not a bad pay after all... yet, I don`t like taking from a jar and putting in an other one so every part with its funds.I just purchased a seek thermal compact(this is not an advertising,don`t buy from them unless you have to(so actually I advise against this product), the negative temperature range simply sucks (-20 is displayed as -2 or even +1 celsius), they don`t offer any support, no reply in more than 2 months since asked...... there are 2 cameras like this - an older belonging to one of my colleagues and my camera which is a little different in design, purchased 1 year later)for fixing "battery-eating" remotes (can`t use the isopropyl technique since key will be killed, provided enough current; there is hardly a 5°C difference between smd parts when constantly eating 20mA for at least 10 seconds (a key usually consumes a short burst of ~7mA in peak for a transmission).. this thermal camera is a big-enough budget hole already, not yet covered...I will also use the microscope for my hobby (which is obviously electronics and embedded, making things etc)...So here come all the questions:Any advice of a cheap, yet powerful (10+mp) microscope that someone uses and is happy with? Manual focus will do.. but I would like at least "electronic focus" (e.g. user-controlled electronic focus).. autofocus is a dream, don`t twist the knife...What objective should I buy? I need to be able to inspect circuits (angled or not, maybe 5~10cm maximum FOV) and I need to see especially VIAs..What should I look for in a microscope characteristics? Any tips?Any variable intensity led ring for microscope that I don`t need to feed from the mains? (tips if you have, I can also search myself on Ali)A nice yet not very expensive stand.. should there be any..Thank you!EDIT: I found some nice page explaining every objective`s characteristics:https://www.aliexpress.com/item/Adjustable-Magnification-100X-180X-200X-300X-600X-25mm-Zoom-C-Mount-Lens-For-HDMI-VGA-USB/33001173563.html

content: Quote from: nigelwright7557 on June 03, 2022, 01:27:10 amNigel is correct. You can pay silly money for smd tools and equipment...or you can go cheap. A Hakko 858D clone hot air station is about $40usd and up to about $60usd. With that and a magnifier you can do what you need to do. I use a 2" UltraOptix 7x lit magnifier to check the work. It helps if you can get a solder mask template (stencil) for your board. That makes applying solder paste a snap. Then place all the parts. They do not have to be exactly aligned and hot air will mostly pull them into place. You can go cheap on the hot air gun too as a stamp embossing gun that sells for about $10usd at places like Hobby Lobby will work too. The 858D allows setting the desired temperature though. Just be sure to make sure the air output is not set too high or the smd parts will go into outer orbit never to be seen again. Places like Harbor Freight sell a "jewler's loupe" set for about $5 usd. I use the 10X from that set. I do also have the cheap dental student magnifiers that have the 420mm focal length and they work well and are about $30usd. So you can spend lots of money or a small amount.Good luck.

Although if you go with the very cheapest 120x lens it does not have a zoom adjustment, you have to manually move the camera up and down to zoom.For a stand I used a microphone boom arm stand w/ 1/4" mount. Pro is that its very easy to move around and reposition, but, it can shake if you don't have it solidly mounted or buy a cheap one.

content: Quote from: Finbarry on October 23, 2018, 12:35:19 pmHi Finbarry!Can you upload the dump of the Macronix 25L25645G, if I ask you nicely?I have the same hardware (HI3516A + IMX290 with 2 USB ports, but no TF slot), without the autofocus feature. The camera worked flawlessly for 5 years and yesterday it started resetting (?) the HDMI connection continuously. The monitor detects the camera on the input, but immediately goes into power saving mode because the camera resets (?) the connection or other anomaly happens. Then the monitor wakes up and detects the camera again, but that immediately goes into power save mode (again) and the circle restarts.I reflowed the camera's PCB with hot air, resoldered the HDMI port, tested with multiple cables and multiple monitors, all with the same outcoming (no dice).The 32.768 kHz crystal and the 24 MHz oscillator works as expected.There was a 3V RTC button battery on the PCB but it depleted to 2.6V so I removed that, it has no effect on the issue. I soldered a CR2032 to the PCB but also no improvement.There are 4 resistors connected the HDMI connector: 2x 2.7 kOhm (R7 &R8) pull up on pin 15 & 16 (SCL & SDA), and what is suspicious for me is 36.5 Ohm (R13) on pin 18 (+5V) because it is a bit high for 33 Ohm. And also there is 47 kOhm pull down resistor (R6) on pin 19 (Hot Plug Detect, it goes directly to the SII9022A pin 54) but if I measure it with reversed polarity it is just 13,5 kOhm (interesting). Can you measure your corresponding values?I need your dump because I want to sort out the possible firmware issue before replacing the SII9022A and the Hi3516A.I guess the FIFO error not full messages does not effect the working state of the camera because I seen on the internet that the same error messages appeared in the logs of perfectly working cameras too. Is your camera was connected to the monitor wen you logged it?My camera's log:Code:U-Boot 2010.06 (Nov 25 2020 - 11:31:36)Check spi flash controller v350...
