I just got a USB microscope and now I can’t stop magnifying things.
It can focus on a broad range of distances, but the standard scale (with its plastic ring touching the surface of the object) can fill a 1600px wide image with an area just over 5mm across.
According to my calculations it’s the equivalent of ~7,500 PPI. It’s great for looking at microscopic details of type rendered with various technologies.
It was also surprisingly cheap: less than $34 with shipping.

I draw, code, and make memes sometimes.
