The solution is to use the camera of a smartphone, webcam, etc. This approach is especially useful, if the frequency is infrared or close to it, because the CMOS sensor is more sensitive in this frequency range.
This blog is supposed to be a collection of random, unrelated, little ideas, thoughts, and discoveries, which I assume to be helpful to a negligible part of the world's population and wish to share out of pure altruism. If posts appear really weird, maybe you have the wrong kind of humor. Many of the posts are science/technology related. If you are opposed to that, stop reading here! Comments, criticism, corrections, amendments, questions are always welcome.

Checking Opto-Fibers with a Smartphone
Todays discovery is simple, but nevertheless practical. Do you need the check optical fibers (e.g. from SFPs or AVAGOs) from time to time? It's sometimes hard to see if they are on, plus you probably do not want to direct a small laser right into your eye.
