A microscope is a potentially useful piece of hardware for microgravity experiments. There’s a wide range of small USB microscopes on the market, at price points from under $100 to several hundred dollars. Unfortunately, these microscopes are generally designed to use a Windows or Macintosh computer for data capture, which is a problem for our purposes.

Information on Linux compatibility for these microscopes is hard to come by. Fortunately, Adafruit sells a USB microscope which they have worked out the Linux compatibility for.

Linux compatibility means the microscope could be used with a small single-board Linux computer such as the $40 Raspberry Pi or the slightly more expensive but more powerful BeagleBone, either of which will fit within the CubeSat form factor.

The Adafruit USB microscope sells for $80, so it’s not a high-end microscope by any means, but it may be good enough for many purposes. It is probable that other USB microscopes can be made to work with Linux as well. For right now, this is a start.
