    [Probably not the most appropriate newsgroup, but nevertheless
    still.]

    Could someone please shed some light on the Supereyes-brand
    USB microscopes' specifications? I've seen claims of something
    like 5 Mpx & 200x optical zoom, but I'm suspect that these are
    (quite) a bit overstated, given the price (like 25 USD a piece.)

    First and foremost, do they really employ a 5 Mpx sensor?
    Somehow, I've got the impression that they may be using a
    640 x 480 (0.3 Mpx) one, and then "enhance" the image in
    software.

    My guess is that I'd need something with a (1 .. 2) Mpx sensor,
    and more or less decent optics (Supereyes' or better), for my
    task. Is there some other brand I should consider?

    TIA.

    PS. Naturally, the device shouldn't require any "custom" drivers or
    software to operate.

    How does that compare to the Veho VMS-004D with 2MP CMOS sensor which
    sells for $56 online?

    Which Supereyes model and sensor are you talking about?

    I recently bought the 200x kind.

    From a quality and resolution POV it looks more like 1MPixel. But that
    could also be due to the lens. Obviously there can't be a $1k lens in
    there :)

    It works out of the box into Windows Explorer. But for using the various
    resolution modes (which affects frame rate) you need their software. The
    one on the CD didn't work and they have a free download. It took a while
    to figure out that only the non-w version works.

    LED: This is not SW-controllable and the LEDs will stay lit even with
    the PC off, depending on PC-configuration and whether you use a powered
    hub (I do). Until USB power gets cut.

    Another thing you should now: The USB cable does not have any rotational
    strain relief so don't use this in a rough environment where it gets
    moved a lot.

    I cannot speak to the specifics of what you are looking at....

    I have been looking at cracked solder joints through a traditional
    microscope, but am not able to get very good pictures. A guy in the
    office has one of those usb microscopes and they are very
    good....but.... the focal point is so close to the device that I
    could only get good images looking straight down on the chip.
    Unfortunately, the cracked leads were only visible when viewing
    through a traditional microscope and tilting the board a lot.

    So, while I think these devices are great, they may not get some angle
    you need.

    There is an adjustment wheel for focus though. Also, there are two
    protrusions to prevent hitting the lens on the object, probably can be
    sawed off.

    .... and buy a fortune cookie factory and clean it out, to get the space
    for a Mantis :)

    Seriously, that and the fact that it easily fits into my briefcase is
    why I bought the Supereyes microscope.

    Can you get a focal point 3 inches away?

    How much did it cost?
     
  8. Joerg

    Joerg Guest

    No, about 1/2" from the protrusions or almost 3/4 from the LEDs.

    For soldering very fine stuff I use a Veho VMS-001, that can do several
    inches and it also has a cap against the solder fumes.


    I think I paid around $120 for it, including a somewhat flimsy stand.
    Could have gotten a better deal but needed it for a job, and fast. I
    found the image quality quite remarkable for that price so to me it's
    definitely worth it.

    Phase contrast anyone?

    I use my Veho mostly with its LEDs turned off. On the Supereyes there is
    a potmeter (a literal one) to adjust brightness from zero to full, much
    better.

    They do. Last time I was in a Ford Fusion it had several. IIRC the
    Mustang we rented had that as well, plus blue pedal lighting for
    whatever reason. You drive a European car and some of those features
    take a while to make it over there. Just like cup holders did :)

    Almost everything has USB these days:

    When I rented a VW in Germany last year I was mighty disappointed that
    it had an automatic transmission. Maybe it was the edition for
    Amerikanskis. Anyhow, I could push the lever to the right and then had a
    whopping seven gears for hand-shifting. No clutch pedal though. To my
    real surprise it had a mph display in addittion to the km/h.

    With film cameras dwindling away, would it be worth working up a mount
    for a decent 35mm zoom lens to a camera, so you could get some distance
    between the subject and camera lens?

    Opinions here --->

    I ran across this camera which is in a different housing then most.
    Says 5MP!

    It already exists. I bought an Olympus E-PL1 plus a Fotodiox adapter
    that connects the existing collection of Minolta Rokkor lenses to this
    camera. Works nicely.

    I don't have this one but if I needed to do some extreme macros I'd
    probably add this to the stack:

    http://www.amazon.com/Fotodiox-Exte...=1363111634&sr=8-11&keywords=Fotodiox+Olympus

    But you can't really us these cameras for soldering and things like
    that. Most don't have realtime output into a computer, have a voracious
    power appetite but no power supply connectors, and you don't really want
    to mess up such expensive lenses with solder fumes.

    Those cars are very sporty, but it also means a lot of stuff is under
    high mechanical stress and gets busted easily.

    That is not a good sign. I like to keep things simple, as in manual
    transmission. My big 1987 Audi station wagon is still traveling between
    Sweden and Germany, spoke to the new owners again a couple weeks ago (we
    are good friends). No serious repair bills, ever. Well, except when a
    delivery truck backed into it but that was paid for by their insurance.

    I am also a strong believer that there should be the least amount of
    electronics in cars. Because electronics in cars break a lot, are
    usually grossly overpriced and designed non-repairable.

    1/3" is really puny. But try this with four-thirds or micro four-thirds
    cameras. I did, and the new Olympus E-PL1 with the 35mm Minolta Rokkor
    lenses from the 80's makes stunning photos. I didn't even buy any
    Olympus lenses with it.

    True, but compared to ye olde grainy 400-ASA slide film even some
    middle-class cameras are better.

    Well, a USB camera is indeed the lower end of photography :)

    With my Olympus it leads to roughly 2x more focal length. So a 250mm
    tele lens is now like 500mm. Which is great but at the other end it's a
    bit of an issue because the lowest focal length I have is 28mm which now
    equates to 56mm. Meaning I've no longer got a wide angle lens which
    might be the reason I'll have to buy an Olympus lens (or another older
    Rokkor) some day.

    It was amazing. When I put on that tele lens after unpacking the camera
    I held it out in the distance, focused and took my first shot. A tiny
    whitish splotch that I could barely see with my eyes was quite visible
    now. Zoomed up ... and could see read the text including a telephone
    number on there. Scary.

    I ruined several shirts with this instant film stuff back in the 80's.

    My truck has two "Cigarette lighters" (one is an unswitched AUX port).
    My wife got an "octopus" for her lighter (that didn't come with one)
    because of all of the devices she uses.
    USB connectors are, or at least shortly will be, ubiquitous in car
    audio systems. Some are remote, in the console but some are in the
    "radio" itself. 2A capability for iPads, even. The iGods have
    spoken.

    Maybe, a bit too oddball and not enough better than USB 3.
