It may be named after the most famous volleyball in history, but “Wilson” isn’t just a great conversationalist. [Hayden Brophy] built the free-drifting satellite buoy to see if useful science can be done with off-the-shelf hardware and on a shoestring budget. And from the look of the data so far, Wilson is doing pretty well.
Wilson belongs to a class of autonomous vessels known as drifters, designed to float along passively in the currents of the world’s ocean. The hull of [Hayden]’s drifter is a small Pelican watertight case, which contains all the electronics: Arduino Pro Trinket, GPS receiver, a satellite modem, and a charger for the LiPo battery. The lid of the case is dominated by a 9 W solar panel, plus the needed antennas for GPS and the Iridium uplink and a couple of sensors, like a hygrometer and a thermometer. To keep Wilson bobbing along with his solar panel up, there’s a keel mounted to the bottom of the case, weighted with chains and rocks, and containing a temperature sensor for the water.
Wilson is programmed to wake up every 12 hours and uplink position and environmental data as he drifts along. The drifter was launched into the heart of the Gulf Stream on August 8, about 15 nautical miles off Marathon Key in Florida, by [Captain Jim] and the very happy crew of the “Raw Deal”. As of this writing, the tracking data shows that Wilson is just off the coast of Miami, 113 nautical miles from launch, and drifting along at a stately pace of 2.5 knots. Where the buoy ends up is anyone’s guess, but we’ve seen similar buoys make it all the way across the Atlantic, so here’s hoping that hurricane season is kind to Wilson.
We think this is great, and congratulations to [Hayden] for organizing a useful and interesting project.
Beautiful project !

Well, I just tried to help, googling for another URL as the one shown in the video wasn’t working (error 404).
I would say the URL I provided is “very similar” (equivalent ?) to the one posted by the project team (see their comment and Mike’s reply, at: https://hackaday.com/2020/08/13/drone-buoy-drifts-along-the-gulf-stream-for-citizen-science/#comment-6270686 ).
May be the antivirus warning is just a “false positive” ?
If you try with the URL in the article (updated by Mike), do you get the same warning ?

Looks like the map isn’t working at the moment, but he’s still providing data. Very nice project.
You gotta use chrome sorry idk why other browsers dont work-Hayden Brophy
I tried it in Chrome first, then tried in Firefox. Both on Linux Ubuntu 18.04 for what it’s worth.
Floated back to land plus other stuff happened. Good Samaritan has offered to take it back to sea for another attempt.

yes, of course science can be done on a shoestring budget what is a very cool thing, but how come hack a day is never really publish any science from say africa on a shoestring budget? (sure they did with the wind turbine kid)
You got leads for us? We’d love to hear it!

I have built a similar project called Floaty McFloatFace, it uses LoRa as its radio and its not currently deployed, unless anyone has a boat ride to offer (in the uk)!?
Can’t you just throw it off the end of Southend Pier (or your nearest one) as the tide is going out?
a trebuchet would get it out farther!
everything is cooler with trebuchet
My only thought is will this get picked up eventually or just become more trash in the ocean.
FROM THE PROJECT WILSON TEAM: We appreciate everyone’s enthusiasm for our hobby project! The correct URL is https://www.projectwilson2020.com and you can also follow along with our many other fans at our Facebook page: https://www.facebook.com/groups/buoywilson
Thanks for letting us know. The link redirects to the one we were using but I have updated it to your version.
Facebook – please do not use for technical projects – many of us choose not to be involved with this stuff; and in any case, it requires a login to view, so almost seems to be a shill for FB.
Data site indicates RH sensor failed. My experience with A/F “waterproof” sensors is that they are not – temp sensors consistently failed within 20 days at over 30cm depth in my fresh-water Koi pond and several ‘waterproof’ RH sensors failed on on three of my four weather stations.
I am not a meteorologist, but am not certain that a sensor 20cm above the ocean is going to provide relevant atmospheric data. I have looked at NOAA weather buoys and the sensor mast package is abut 2m above the water.
Wouldn’t the Relative Humidity (RH) at 30 cm depth in a pond be 100%?
Never mind, you were just mixing examples…
I agree with you about Farcebook.
At least one of the Temp sensors have failed too!
That’s cause there not made for 130F heat, right now wilson is sitting on a pier baking. When hes actually in the water all the temp sensors work just fine. -Hayden Brophy
Reminds me of the Ocean Floater Project hailing out of New Zealand this one lasted 400+ days though touring the pacific ;-)

The sailor in me immediately thinks this is very bad idea indeed.
Ships and boats use the ocean too. This little box is not going to worry a commercial freighter, but this can cause serious damage to sailing or motor vessels. Things like propellers, steering gear & wind vanes can easily be damaged or disabled hitting something like this.
Boats will almost always maintain a watch (for other vessels and floating debris), but this would be next to impossible to spot and is not going to show up on radar, and likely not FLIR in anything but the calmest of weather.Why use a black box? Orange and yellow are freely available. How about some kind of mast to aid in visibility? Something like a fibreglass whip antenna with a polystyrene ball painted a bright colour would be orders of magnitude and be cheap as chips.
Kudos to you for your efforts and imagination, but please think through the consequences when you’re releasing your projects out into the environment.
Serious? This tiny low density thing wouldn’t do crap to any ocean going vessel. Not to mention the actual probability of hitting it in the first place…
Yes, seriously. If you don’t know a someone who’s hit something at sea, then you’re clearly not a sailor.
Problem is if you become “responsible” for your flotsam and jetsam especially in busy shipping lanes. It did prevent us from a similar project . As Shane said some basic care in the painting and making visible department would of been useful. I’d also would of liked it to have had it’s own HF radio rather than relying on a Satellite transponder it’s all stuck together modules
That said he is only a teenager so kudos to him for trying and actually delivering something let hope his next one will be even better !
Kudos for the kid for the project and build. Yes, it ain’t perfect and could have been way better with a few different choices, but it’s still great. But I’m not as happy about the crew that launched it. The restaurant promo and political apparel shouldn’t have been part of the video.
