This Electric Surfboard Has a Secret Inside!

Liking the video tends to make it a little more popular so I would appreciate that very much. Working on a hydrfoil and electric jet ski next.

I’m a 67 year-old guy and you are a great inspiration to me! Because of you and your extremely helpful (and humorous) videos, I built a motorized kayak using a 70mm water jet thruster, the same 400a ESC, 56114 motor, and 4 6000maH batteries, with motor and ESC cooling. It’s a BLAST!!! And all thanks to you for pioneering the way! Thanks so much for all of the many hours of enjoyment I’ve had so far!! ❤️

For heat dissipation, make the bottom of the box aluminum with the fins for the board and flush with the bottom. Thermal paste as many hot components directly to the plate before bolting down. Combined with your water cooling system to pick up the slack, the bottom plate can pull double duty as heat sink and fins.

Great work, amazing creativity! If you are our engineer, I believe our products will be stronger!

I've never even heard of an electric surf board. This is such a cool idea and a great execution. One thing I'd add is using lightweight PLA might help waterproofing a little bit because it foams up a little filling in all the pores and holes in a 3d print. I'm surprised at just how well it works already. I hope you can get those cooling issues in order for the second impeller.

Very cool, I used oil bearing seals on 3d printed jet drives and they work well but the seal that is not cooled by water tends to heat up and wear out. The issue i had on my electric surfboard is it was built too wide and heavy, while very stable it wasn't fast. Have you thought about using power tool batteries? I'm using 4 dewalt 9000mah batteries. Great video as usual and engineering 👏.

As someone who is heavy into 3D printing and the 3D printing community this might be the coolest thing I have ever seen. Congratz dude. Absolutely amazing. Even tho you didn't model everything yourself you still made the thing work.

Love the update. I made my own surfboard based on your original design but replaced the 53mm impeller with a 70mm impeller. I also simplified by going with a single drive instead of a dual drive. My biggest problem on initial testing was my buoyancy, it was more submarine than boat. I added rigid foam to the bottom and sides to also assist in stability. It worked great. I must say you make it look easy to ride but it took me the better part of a morning to just stay on it for a minute without falling off. My next improvement will be the battery compartment, to make it completely waterproof and allow the space for more batteries.

This was awesome! Next project needs to be a E-Foil!

Вот это проектище! Как всегда отлично! Один из лучших каналов Ютуба.

This is freaking awesome! Young, talented and fearless engineers like that give humanity hope.

Great video as always! Love your work. 1:33 a bearing should always be inserted by hitting the OUTER ring, not the inner ring. This could damage the new bearing easily. Might not be as bad when working with plastic instead of metal but still made me wanna comment. Otherwise, very nice work

“I am all alone, I have helmet, life west and ID, so it easier to identify the body. “ That had me laugh a bit to hard! 😂

very awesome dude, looks like a whole lot of fun, I never got into surfing because the waves never lasted long enough for me to enjoy it, but this, this would be fun.

The journey you take us on with the builds is always worthy of a like. I'm a person that likes quick closure, although your projects might have future iterations, the videos always have that 'complete journey' feeling. I'd blow more smoke up your a$$ but I think those motors might end up doing that for you haha. Thanks for the content

Good design man. I LOVE seeing people using 3d printed metal parts, its the future of manufacturing. Minimal waste, maximum flexibility.

I am glad to see how nicely it worked out!

Its time to create your own E-Foil! This 3d printed impellers looks amazing!

I enjoy it he way you explain what needs to be explained. Nothing more. These videos are easy watches and I’m not even skipping through.

As an armchair engineer, I have to add that two impellers in series don't move double the water, they just move the water harder, doubling the pressure. The result for the power demand is the same (parallel or series pumps), it's gonna double. But doubling the pressure on a jet with an additional stage grants the opportunity to use smaller nozzle diameters more efficiently. Thus increasing the top speed without having to increase the motor speed. Great build by the way, impressive top speed!
