Instructables individual [rog8811] was seeking to develop a fog horn that resembled hand-pumped units discovered on little ships in the early to mid 1900s. His budget plan was a bit limited, so he set off to develop the least expensive replica possible.

While the original horns were likely built from steel, copper as well as wood, he opted to utilize inexpensive plumbing elements he discovered at his regional hardware store. He utilized a basic double-acting air pump to drive the horn, integrating it with a somewhat customized bottle trap. The trap was shortened, as well as a diaphragm cut from a meal washing glove was added to produce sound.

He added a few a lot more pieces of PVC piping to improve the output, providing him the results you see in the video below. He states that the very best thing about his style is the capability to quickly modify the pitch as well as volume of the horn by just adding different drain elements to the pump.

Watch out vuvuzela, there’s a new inexpensive as well as irritating horn on the block!
