Review of Mamba shield for Arduino Uno

ABSTRACTThis document analyzes the Mamba shield for Arduino with several experiments of powerlines communications over DC lines and AC lines. Principally, I’ve tried to guess the baud rate that this product can reach without transmission errors. INTRODUCTION Power line communications technology is a way of carrying data on a conductor that can also be used for power transmission. You can use it…
How to Position Fresnel Ambient Light Rejection Screen

How to Position Fresnel Ambient Light Rejection Screen

Fresnel ambient light rejection screen can reject ambient light and improve the contrast of the projection. However, it's critical to position the screen correct without to the projector. Otherwise, the effect will be discounted significantly.Projector can be installed on the table or from the ceiling. So there are two ways to install them.On the table or stand:Projector installed on ceiling:…
