Endoscope fun

 After my fun trying to photograph a typewriter serial number I had a look into the cost of endoscope cameras, and basic units are amazingly cheap these days - for less than the cost of a couple of beers I picked up this little toy from Amazon

to which I added a USB C converter and plugged it into my Ubuntu laptop, ran up cheese (a webcam management app), and selected the USB device, and hey presto! - it just worked

and if you've ever wondered what a 20c coin looks like in close up, here's a test image

Ok, it's not the greatest quality photograph, but I'm quietly impressed that it took me longer to get it out of the Amazon delivery satchel than it did to get it working ...
