How to Make a Doorbell

This website is similar to the one below. It has direction and materials needed to build the proper door bell. The website is also full of links which allows viewers and user to gather more information. The links provides viewers and users other ways to accomplish the same project. However, this website is lacking a few things that the other site had. For example, a video and pictures. I believe that most people preffer visual effects when doing a "How-To" project rather than a list that explains how to do it. Mostly this website provided simple instructions on how to make the project. In addtion, the other site was used for a laser. This site is for a doorbell. They both have the same mission, to alarm.
