Endoscope as a bore scope?
This showed up on the FBK AR builders forum.
Off of Amazon and runs as an app on IPHONE or Android.
USB links to phone.
Potential? The pics were decent on the page but probably not as good that higher end equipment could do.
@hypo That looks GTG..:smile:
Trolling around on Amazon, they come in various diameters. That one is 7mm. Others are long for plumbing inspection and can hook to a laptop. I saw one that was 5.5mm diameter.
