It's a completely un-annotated schematic. To build the prototype, someone has to select suitable electronics, put it together on perfboard, and last but not least strip a power-cable to have bare-ends to solder to the input of the bridge rectifier.
You really think that this person needs an additional warning about the dangers of 120V mains?
