Make your own IR remote that can reach anywhere

My home theater is far away from my bed and the remote is unreachable there. Many a time, I thought of controlling the home theater from my bed to enjoy music anytime (due to laziness of course). So, I did some search and found this great video from GreatScott. That video provided me enough information to get started. Then further, I taught myself the remaining things to send and receive IR codes from IR receiver and transmitter. After building this you’ll be able to control anything that is unreachable from your spot, provided you have enough wires.”
