Yet Another Scanning Monochromator Build

A while ago, I saw a video on the signal path in which Shahriar modified his Verity EP200Mmd monochromator/detector and turned it into a scanning monochromator. Inspired by his work, I decided to do something similar. Since I do not have the equipment to make the mechanical pieces, I decided to take another route. In this post, I will show you a simple and non-intrusive way to make the EP200Mmd a scanning monochromator. A video discussing the build and some experiments is included towards the end.

Building A Laser Oscilloscope

You can generate some pretty amazing patterns by shining a laser onto a mirror mounted on a vibrating speaker cone, a lot of people have experimented with this kind of laser show. But how about building a true laser oscilloscope that is capable of displaying signals? In this post, I will show you just that. For those who are impatient, I included a video towards the end.
