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.

Simple Optical Encoder For Wheel Rotation Detection – II

In my previous post, I showed a simple optical encoder circuit that is TTL compatible. The main drawback of the circuit is that it does not provide enough resolution since the encoder is only triggered when the mounted mirror is aligned.

Simple Optical Encoder For Wheel Rotation Detection – I

To detect wheel rotations in model vehicles, we would need to install some kind of sensors on the wheels to be monitored. Continue reading ‘Simple Optical Encoder For Wheel Rotation Detection – I’ »
