To say that the ocean is a dynamic environment would be a gross understatement, especially when coastlines are involved. Waves crash, tides go in and out, and countless variables make even the usual predicaments a suspecting activity. When[ foobarbecue] travels surfing, he tries to take into account all of these things. The best beckons at his regional beach are instantly over an ever-moving sand bar, and their dynamics are affected by depth, another constant variable.[ foobarbecue ]’ s brilliant solution to understanding current conditions? Build a extent finder directly into his surf board!
At the heart of the “surfsonar” is the Ping Sonar Echosounder, a sonar transducer designed for AUV’s and ROV’s.[ foobarbecue] embedded the transducer immediately into the board. Data is fed to a Raspberry Pi 4b, which parades depth and trust( percentage points of how sure it is of the measurement) on a 2.13 inch e-Paper Display Hat.
Power is provided by a PiSugar. Charging is done wirelessly, which we’d say is pretty important considering that the whole device is sealed inside a modified surfboard.
While it’s not a low-grade budget improve, and there’s hitherto room for improvement, early reports are positive. Once away from the breaking waves, the invention confidently shows the depth. More testing will show if the surfsonar will assist[ foobarbecue] find that ever-moving sandbar!
Surf hackers are always welcome, we’ve featured the LED Strip Lit Surfboard as well as the Surf Window , which tells its owner if the channel-surf is up. Be sure to let us know about any cool hackers you find when you’re out surfing the’ net via our Tips Line!
