  • Some test shots with Andonstar ADSM 302 HDMI digital microscope

    Some other notes:
    +Good focusing range from approx 40mm to Infinity!
    +Plenty of working distance available if you want to do soldering or something like that.
    -Bit too laggy to do something like soldering under the microscope, don't expect anything with 30hz screen update rate to be better than this tough.
    +Build-in display is better than than I expected, really good viewing angles and resolution is "good enough" (not specified but I'd WAG 480P to 720P)

      Excellent image quality. What's the magnification? Variable?. Do you have an HDMI socket on a laptop??

        Fixed magnification so it depends on distance. (plus 4x digital magnification)
        40mm focusing range gives you about 4mm wide area to view. 2X digital zoom looks reasonably good on 27" full HD display so that gives 600:2 or 300X magnification if you want to calculate it like that.

        Tested with separate display with HDMI input, I'm not aware of any laptops that would accept HDMI input.
        Pictures shown are saved to memory card (micro-sd) and transferred to computer.

        Haven't tested the USB functionality but from what I have read its lot more limited.
        This is designed with HDMI and sd card in mind, not USB use. (good thing mostly as video frame rate and lag tend to be lot worse than HDMI)

            Worked for me.

            Do you think this would work well enough to mount over the spindle to see when turning really small parts? I see on Amazon they start at $225CAD, which is a little much to experiment with.

              Same here and that is typical imgur. Their priority is to feed you advertising, not serve images. And yet people still insist on using them. They are just another photophuggit.

                  I'll have to rig up something and try it out.
                  Preliminary guess is that it would work, slight lag doesn't feel so bad if you are feeding from handwheels vs. using handheld soldering iron or such.

                    My Lenovo ideapad 310 laptop has an HDMI port, but I don't know if it works with input as well as output.

                      I haven't had change to compare with anything else like stereo microscope but based on even a quick shoddy setup I can tell that its MUCH better than having no microscope at all!

                      Makes amazing difference when you can actually see if the cutter is cutting, if its dull and how close to the workpiece you are!

                      Here is a 0,13mm pin with 0,008mm step (according to my DRO)



                      And here is 0,09mm pin



                      My wifes hairs are thicker than that!

                      (again, chinese DCGT insert, this time DIY sharpened as it was already used)

                        And for the metrically limited folks that is less than 0.004" diameter pin.
                        0.0003" DOC. With carbide. And way below any speed recommendations.

                          You didn't order your lathe with the 800,000 RPM option?

                          Great images from the camera, much nicer than a loupe.

                            That thing is really cool.

                              that's fascinating - the carbide insert is not even "sharp" and you can see it's made by pressed pieces of smaller material - always was told that but never actually seen it like in that first pic
