My name is Jon Eide Pettersen, and I am a mechanical engineering student at NTNU in Norway. One of my greatest interests is designing and constructing stuff, along with diving and underwater exploration. When I was in high school, I decided that I wanted to build an ROV. Since then, I have built an HID diving torch, participated in building a hovercraft, and built a DPV - diver propulsion vehicle. The purpose of this site is to document and share information about these projects, as well as helping others who are working on similar projects.
