These small arm-mounted propeller units can carry a skin diver through the water with minimal effort.
YouTuber “PeterSripol” had only a week to prepare for his trip to Hawaii. Rather than purchase a set of fins or a snorkel, he instead hooked up two T100 thrusters that he had lying around to wrist straps. In his setup, these thrusters are controlled by a button interfaced with an Arduino that allows the user to select one of three power levels.
The required battery, as well as other control components are housed inside a waterproof box, and quite a bit of effort was put into making good (and hopefully waterproof) connections!
Unfortunately, the fun was cut short by a cut wire, but it looked awesome nevertheless! You can see the project in action below!
