G1200 Microscope

Last Updated or created 2022-08-16

Another good suggestion by Bigred.

We are all getting older and electronics smaller. It’s hard to see if your soldering blobs are okay!
Those blobs can reflect the light in a way that it’s not visible anymore to check them.

So i took Bigreds advice, and bought a G1200 Microscope.
It’s a cheap but helpfull little gadget.

  • 1-1200 times zoom
  • 7inch screen (720p)
  • SDcard
  • Lipo battery
  • Recording on micro sdcard in 12 mega pixels pictures and 1080P Video.
    (even got a timer)
  • Focus button, and extra lights (There is a light source in de camera head, which can be adjusted by a knob)
  • When connecting to your pc, you get 3 options
    • PC Camera ( … so you can record using your pc with for example OBS)
    • Mass Storage, to read the SDCARD
    • Rec_mode ?!? – No idea yet

Below some examples:

SDCard Access:

Access to the sdcard is a little hard. Connecting via Mass Storage is a solution. But i’ve put a little piece of tape to get the card in or out of the slot.

You can view the recordings on the Microscope itself. So i was wondering, can it play any other movie files?

I placed different MOV files on the sdcard, but the microscope skipped the ones i places on the sdcard myself.

I started to look at the metadata, and saw a Codec ID

Tried to change this with ffmpeg, but it would not change the way i want.

ffmpeg -i VID_002.MOV -c copy -map 0 -brand 'qt   2016.04.21 (qt  )' VID_007.MOV
