Which HDMI Microscope Camera and Zoom Lens for soldering
<< < (7/11) > >>
Sorama:
I got an Adonstar 409max since this week and although the picture quality is more than good, the magnification is too much as in the overview of the DUT is very, very small.

Putting the camera higher makes it hard to follow on the display as it is then (way) above my head.

I have been asking if there exists a Barlow lens but that does not as the diameter of the camera is different from what exists in Barlow lenses.

Once I have a better monitor, I’ll try with the hdmi connector.

I found the right microscope that I wanted (and want) to buy.

I'm using a 24 inch iiyama PL2483H monitor directly connected to the HDMI output of the camera.

The motion on the screen feels smooth and instantaneous. When focused on the PCB I can put my finger on it sideways and on the tip of the finger the print is sharp, but the top side starts to blur a bit. But with an ic the depth perception is good enough to read the writing on the IC and still see the traces on the PCB.

All in all for me it will be a great improvement over the stand alone 7 inch one I used before. Attached is a picture of what that looks like with a RPI PICO.

And the same PICO under the new one. Even with the whole board on screen it still is big enough to work on. See the watchmakers Philips screwdriver tip near the RP2040. Also notice the difference in height between the two cameras.

I see in the Eakins store that the cameras I need are made on the IMX385 sensor. However, I am interested in the one with autofocus, it is 2 times more expensive. Externally, the cameras are the same, but without autofocus the power supply is 5 volts, and with autofocus - 12 volts.

Actually, I like cheap solutions if they solve the problem. Unfortunately, in the case of the microscope, everything depends on the sensor. I have already tried cheap solutions, and I do not understand the enthusiasm about this junk.
PlainName:
Autofocus is a double-edged sword. For PCB work I couldn't get on with it, but for other stuff it is useful. Main issue I had was if, say, your soldering iron or tweezers got in the target for autofocus then the thing you're actually trying to see (the PCB) is out of focus but the view of your tweezers is great!

Also, and not sure if it's just this camera or all of them in general, when turning on initially it would go to one end of the focus range and stick there until something it could latch onto persuaded it that was the wrong end. Not end of the world but irritating.
