content: For C$73 (about US$54) BangGood (http://www.banggood.com/search/1119592.html) is now selling a microscope that can be adapted for inspection and soldering. It shows its image on a 6x9 cm 720x1080 color LCD, and it will even capture pictures or short videos to a µSD card.As BangGood supplies it, its mount allows only two or three centimeters of working distance (too little), and magnifications of no less than a few hundred times (too much). It can be focused, however, to much greater distances (at least a meter), and it's easy to construct a fixture that provides useful magnification at useful working distances. For example, it took the attached picture (of an MCP4725 on a millimeter scale) at an objective-to-object distance of about 16 cm. The image looks sharper on the screen than in this JPEG.The other attached picture shows the fixture that I built for it, using an existing mounting hole in my Panavise base as its root.

content: What kind of software do people use with these cameras?, I bought an andonstar,http://www.ebay.com/itm/371767002110which seems to work fine, but no software.Windows find it, and I can use it as an webcamera (skype etc), but I would guess there exists software that enables you to use these cameras in a better way for microscope use?(sorry to hijack you thread.. )

content: @neslekkimI don't consider it hijacking at all; you raise an appropriate question.The Andonstar that you got seems to be intended for different uses from the device I got from BangGood.My device is indeed recognized by Windows (as a "TIGA device"), and Windows finds a driver for it, but it is then barely functional as a Webcam, with a frame rate (at its 720x1080 setting, at least) of about 0.15 fps. Moreover, when it's connected to Windows, its screen shows only an unchanging USB logo, so images can be composed & focused only via the Windows screen. That feedback loop is slow to converge, to say the least. It reminds me of working in an old batch-process programming shop, or in an old wet-process darkroom. (Yes, I'm old.)I will connect my device to Windows to recharge its battery from time to time, but probably I'll never try to use the connection for data transfer. I got the device because of its screen, so that I could use it as a freestanding scope. If I had a useful driver for it, I might use it differently.

content: Quote from: neslekkim on March 14, 2017, 12:13:56 pmI own one of these andonstar USB microscopes myself, and I get the best image quality using the built-in "Camera" app/sofware in Windows 10. You can also use VLC (File -> Open Capture Device), but the image quality is horrible for me.Anyone have good recommendations for cheap optical microscopes? I personally find it way too difficult to do work with a USB/digital microscope, anyone have any experience with the cheaper stuff? Like:www.ebay.com/itm/252825012307orwww.ebay.com/itm/252825009640

content: I tried and bought many options of digital microscopeThe best deal is not to buy a digital microscope and buy regular scopeMine is this onehttps://www.amazon.com/gp/product/B0056X4RRS/ref=oh_aui_detailpage_o09_s00?ie=UTF8&psc=1If you insist on the digital one, and don't have up 5K available, a reasonable one is this one and will be in promotion in 2 dayshttps://pt.aliexpress.com/item/new-2016-Andonstar-HDMI-microscope-long-object-distance-USB-microscope-double-output-soldering-tool-bga-smt/32614052280.html?spm=2114.13010608.0.0.IWP23xOne that I dream is the Tagarnohttps://www.tagarno.com/digital-microscope-tagarno/tagarno-fhd-zapBut don't have pocket for that

content: My advice is to go for an optical STEREO microscope. The difference is huge, and you can find a used stereo inspection microscope for about the same price. The 3D view and the image clarity of a stereo optical microscope are huge advantages.Once you looked through a stereo microscope, you will never want to go back to a WebCam with display.Later edit:If you want to take pictures or movies, then a trinocular optical microscope would be even better, but you can still do it with a binocular one.

I don't have a tip right now, but ebay and Craig's list might be a good start. Not saying this is the best, but it took 1 minute of search:http://www.ebay.com/itm/Dissecting-dissection-inspection-binocular-microscope-lab-metal-frame-20X-new-/382010707394http://www.ebay.com/itm/Dissecting-dissection-inspection-binocular-microscope-/380333251526http://www.ebay.com/itm/Boreal-Trinocular-Inspection-Microscope-Head-Binocular-/302164856073

content: Has anyone found polarizer add-on filter for the Andonstar microscope and the likes?The lens / ring light assembly is so small that it's quite difficult to find anything that could fit.

content: Quote from: RoGeorge on March 27, 2017, 12:42:29 pmBe aware that 10%-15% of people cannot see in stereo. Such people perceive depth using the many other clues in the normal environment (e.g. smaller => more distant, bluer => more distant).A quick test is to ask someone whether they were hopeless at ball games at school. If, for example, they swung at tennis balls and often completely missed them, then it is likely they can't perceive stereo pictures.

content: Quote from: tggzzz on March 27, 2017, 03:15:35 pmYMMV. I have severe amblyopia, ('lazy eye') so I can't see in stereo, and I have always been hopeless at ball games - BUT I found to my surprise I can get some sort of depth/stereo effect when using a stereo microscope, after a bit of acclimatisation. This is very wierd, as it's not something I normally experience. I also find that my astigmatism does not need correction when using the microscope - this also holds for binoculars. Probably something to do with which part of the eye lens gets used, so different eyepieces may make a difference. I use an Olympus SZ40.

content: Good and budget option:https://www.aliexpress.com/item/new-2016-Andonstar-HDMI-microscope-long-object-distance-free-shipping/32614052280,I like it.I will recommend you Altami Studio program (http://alelso.com/projects/altami-studio/), you can display everything on the big screen and it's very convenient.
