Riding The Worlds Biggest 3D Printed E-foil

[JTCF]

I think it would look funny if you have just a chair and no board. Cruising through the water, while everything that's above the water is just *chair*

I’m a retired 76 year old broadcast engineer. I’ve been following your adventures since your early quad days. I think this ranks at the top of your many achievements. Watching you tune the sensors and adjust for CG is impressive. The array of components you have available to you makes me kinda wish I was born later. Such great stuff you have available these days! Watching your various exploits is the most fun I can have sitting in my grandpa chair. I’m sure you have a great future! Thanks for the fun.

You need mirror/chrome tape on the masts so they will be virtually invisible from a distance.
That way it will look like it is flying to the admiring spectators ...

I love that the kids recognized you. Very cool project.

As a disabled person... I WANT ONE!!! when you perfect it, I want to build one for myself. This is just my dream machine to be able to go out on the water alone without having to rely on others -autonomy as a disabled person is just a dream come true.

I love all the random interactions with the curious people. Daniel spreading science and engineering is awesome!

As a self confessed YouTube addict, I feel that many of us have an unrealistic bar for what's a cool new invention nowadays. But this surpasses even that content saturated bar by absolute miles. Most amazing thing I've seen on here in years, and I really hope to see more improvements and innovations around this thing. So wish I was capable of turning one of my boards into a majestic lumbering beast of a foil like yours!

I'm just waiting for the ridable ground-effect surfboard now. Impressive work

[GoodkatNW]

Should call it the Both you and the machine make the same sound, so it seems fitting

The best about this is the genuine joy this guy expresses by the hand of his own work.

FYI, several of the most common canned spray foam WILL warp your print. Its a common trick with coolers to upgrade the insulation. You have to get the "Low expansion" one. Theres like 3 different types- low expansion isn't very common. Otherwise it'll pressurize and absolutely blast out your 3d print.

Consistently, the most enjoyable content on YT. Wish I had a fraction of your engineering chops.

19:39 are you rctestflight?
That's great!

[DGRS]

I have ZERO patience to do as much design and testing as you've done on this thing, but I am absolutely enamored with how much progress you've made with this thing. It's just too damn cool. GREAT WORK!

Green screen section is a great addition. Nice work!

They sell dielectric grease to use on those waterproof connections. You can also substitute it with vasoline. The grease fills the voids and prevents water from getting into the connectors and prevents corrosion. Many connectors state you must use the grease. But very cool design!

You should point the sonar sensors forward, like 45° this way you get a more stable signal, as wave heights have less effect. It will also naturally stabilize better, because if you pitch down, the sensor readings will also shorten, instead of getting longer (because you're moving it now to a negative angle if you pitch down). Same for pitching up, as this will increase the sensor readings.

You just need to do some trigonometry to figure out the real height :)

It will also do some look ahead, giving the board a better chance to raise above waves coming towards you.

I would also recommend moving them in the center of the board, and stack in a line in direction of movement. This avoids that if you turn, one sensor reads high and one reads low.

It would also make sense to add a third sensor, so you can use median instead of average to cancel out ripple noise. This would also avoid that waves can cause harmonic effects on your stabilization circuit, which might be what you experienced in the end.

Never seen you this happy before...
Great job.

[tweaker]

Congratulations dude... After all your hard work I am glad that it worked so well for you... As Scott Manley says "Fly Safe!"

[Merivio]

With the chair added, this is one of the most fantastic things I've ever seen!
