I wrote about the terrific Plugable USB Handheld Digital Microscope in 2015. It’s on sale for $29.70 right now.
I had the earlier version of the Plugable USB Handheld Digital Microscope and liked it a lot. The second version just came out and I love it. Smaller than a prescription pill bottle, the microscope has a USB cord that can be plugged into any computer. Download the software here and start looking up close at money, leaves, circuit boards, bugs, skin, hair, and anything else.
The scope has a built-in, adjustable-brightness LED for illumination. The brightest setting is not always the best – try different levels of illumination and let the software auto-adjust the contrast. I also learned that in order to see things at the maximum 250X magnification you need to follow the instructions in the FAQ.
The scope comes with a suction-cup gooseneck mount that is very stable, and a plastic board with a grid pattern, which helps you align and locate the thing you are looking at. You can also simply hold the scope against things. The software takes still photos and movies, and hasn’t crashed on me yet (the earlier version was buggy).
At this price, the microscope is an amazingly entertaining device and I find myself grabbing it to check out all sorts of things, including splinters, skin cuts, bugs, and playing card designs.
