This is a complete build of the "DIY TV-B-Gone SHP (And Save $45)" project by "dark sponge" on Instructables. I followed his instructions as close as possible, and this is what I ended up with.

In the original Instructables build, the builder chose to make it as small as humanly possibly, by bending the pieces together and soldering all the components into one massive ball of electronics. I had my own idea of attaching all the components to the top of a 9v battery clip. This way all the parts would be solidly held to a almost completely flat surface, and I felt that it would be way easier to fix problems should the occur.
