This video is about the whole building process of a electronic Hydrofoil for a Laser sailboat.
The last video documented not to whole process. The Ruderfoil and the electronic height-regulation-system were missing.
All this was partially my graduation work from the "Gymnasium" (like highschool) and partially from the the "Nationaler Wettbewerb, Schweizer Jugend forscht" (Swiss Youth Science).
Thanks to all the people who made this project possible!

I'm a Tesla Senior Staff engineer and I must build one of these now too! THank you!!

@johnanderson9506 3 года назад

Congratulations on this very interesting project. Please ccould we have a video of the boat sailing. John

Brilliant - how wonderful to combine two things that you obviously love - well done!

@CarkeekW 7 лет назад

Great work and would be good to see on model boats also to allow the first ever properly controlled foiling cats !

@musFuzZ 5 лет назад

Wow super impressive. Love how you combine electronics into it. I am in the prosess of combining two kayaks to a catamaran, and sail on it, and eventually hydrofoils. All transportable on a bike trailer for my electric fatbike. And the idea, is to chain drive my fatbike motor into the boat propeller. So it is a E-bike powered boat.

@20itube09 4 года назад

thats really interesting. do you share your work somewhere ?

@manp1039 2 года назад

nice build. it would be fun to build an RC scaled-down version. at what speed does your boat hull lift out of water?

@user-vm5wx6oi5w 6 месяцев назад

A very cool project! The fact that you made it alone is very impressive. How can I contact you to find out some of the features of the technique?

@radosawrettka1609 7 лет назад

Great Work. Cannot wait to see your boat in full wind under the sails :) - did you try it ?

@skyak4493 7 лет назад

First DIY electronic height control I have seen. I wonder if it would be legal for Moth class.

Congrats from Tessin!!

@johncaro4598 2 года назад

I must have missed something I don't see you sailing the sailboat with hydrofoil I see it being towed did it ever work?

@lukasreitemeier 10 месяцев назад

Nope, you didn't. It was the plan to try it with wind, but on the two occasions I tested it, there was no wind ...and I would need at least 4 bf, because the foils are oversized due to the building materials used (cheap wood and steel).

@chrishughes8188 6 лет назад

Really cool. But... Did you SAIL it??

@johnrflinn 5 лет назад

My thoughts exactly.

@pacificmeister 7 лет назад

Hi Lukas, super Projekt und wirklich toll das du die elektronische Hoehenregulierung zum Laufen bekommen hast. Respekt!! Baue derzeit an einem elektrischen hydrofoil surfboard und denke auch ueber eine derartige Steuerung nach. Dann koennte es jeder am ersten Tag beherrschen, wie ein Segway fuers Wasser ;). Hast du dein Arduino Projekt irgendwo veröffentlicht? Wuerde mich sehr interessieren. Viele Grüße aus LA

@hellojay4885 7 лет назад

Top gemacht. Gilt für Eure beide Projekte....falls Ihr das mal kombinieren wollt sagt Bescheid an rebel2007@web.de Gruß Jörg

Ich habe deine Videos gesehen - sieht hammer aus! Mein Arduino-Code ist am ende des PDF's unter folgendem Link: www.dropbox.com/s/bizrrhdzduxnlne/Lukas%20Reitemeier_Fliegen%20%C3%BCber%20dem%20Wasser%20-%20Konstruktion%20und%20Bau%20eines%20Hydrofoils.pdf?dl=0 Allerdings würde ich mal einen Spezialist im Berich Regelungstechnik anfragen, wie die Grundstruktur einer solchen Regelung aussehen müsste. Bei meinem Projekt ging es eben auch darum wirklich alles selber zu machen und dementsprechend gibt es bei der Regelung noch viel Verbesserungspotenzial. (Bei meinem Programm wird einfach mit einer einstellbaren Frequenz der Ist-Zustand mit dem einstellbaren Soll-Zustand verglichen und anhand eines einstellbaren Korrekturfaktors wird dann schlussendlich der Anstellwinkel vergrössert oder vermindert. So konnte ich die kritischen Variablen auf dem Wasser justieren.) Würde mich riesig freuen mehr von dir auf RU-vid zu sehen!

@paulopolonio 4 года назад

I think your main goal was the eletronic height control, could be the reason for completely disregard the KISS concept (there are already far more simple and less fail prone ways to mecanically do that), but lets put this aside, for now...at which speed have you foiled up, would you be able to reach such speed under sail? Adding lateral foils to a sailboat, you might have think in assymmetrical lift, to fight heeling forces, how would you reinforce (or completely replace) not only the spar but also, the mast's foot structure, to deal with the increased loads, without adding too much weigth? And finally, there is already on the market, a complete plug&play foil kit for Lasers but ... without Eletronic Heigth Control, for sure.

hi, im trying to make rc version of hydrofoil boat but i have a lot dificulties with electronic stabilisation system..could you please share your arduino code

@lukasreitemeier 7 лет назад

In the PDF on this link way at the end is the whole arduino-code... www.dropbox.com/s/bizrrhdzduxnlne/Lukas%20Reitemeier_Fliegen%20%C3%BCber%20dem%20Wasser%20-%20Konstruktion%20und%20Bau%20eines%20Hydrofoils.pdf?dl=0

@emielnefs4005 5 лет назад

@@lukasreitemeier Would you please send the file once more, I am trying to make a similar project but I found the code very complicated to make, the dropbox link has expired.

@MrPILOTSTEVE59 5 лет назад

Very Smart. I wonder what it would do under sail speed wise?

@bibibiskouaz5867 5 лет назад

Looking forward to seeing you in the Alinghi team!

@georgethompson8834 4 года назад

I hope you are keeping up with this video. What airfoil did you use and how did you calculate the size needed for the mass of your boat?

@zip7806 6 лет назад

YOU GONIG TO SAIL IT OR WHAT?

@bearingef 7 лет назад

Hello Lukas Very nice project! I have a question about the ultrasonic sensors. Did they work well for you in the water, or would you in hindsight suggest a different type of sensor?

@lukasreitemeier 7 лет назад

The waterproof JSN-SR04T sensor worked verry well, especially for the low price. Even when the sensor got wet, the readings were accurate!

@kamakiri700 5 лет назад

really amazing

@DouglasHPlumb 6 лет назад

Did you use sweeps (chirp) to read distance?

@Redafto 6 лет назад

Haha wie cool! Hab deine Maturaarbeit mal grob durchgelesen. Echt Respekt :)

@lukasreitemeier 6 лет назад

Danke!

@Skysurfersim 2 года назад

Nice! Please never wear gloves when working with spinning tools like you did at 4:50. Very dangerous.

@lukasreitemeier Год назад

Thanks for the tip, makes absolutely sense!

@johnrflinn 5 лет назад

Brilliant! Thanks for sharing.

@___Chris___ 4 года назад

How did you come up with the decision for how much wing area is appropriate (relative to your boat weight and target speed)? What made you chose this specific wing profile? There are so many to chose from (e.g. as NACA numbers) ... Btw: Interesting project, especially with the successful implementation of an automated electronic stabilisation. Congratulations! _(note: I also speak german, just in case this makes answering any easier)_

Hey Lucas I was wondering if you could share your CAD drawings.

@keng-peichiang5043 5 лет назад

This video looks fine to me

@bobquigley1957 4 года назад

Outstanding!! Well done.

@pr-jj6nc 7 лет назад

Do you have plans to sail the boat under it's own power? I would love to see a video on that

@lukasreitemeier 7 лет назад

This was my original plan, but at the moment I have got to little time to make a third test...However I would love to see my construction fly under it's own power! The main problm is, that a high efficiency and practicallity were never my main design goals. I assume that it is possible to fly just with wind power, but I estimate a needed wind-force of 4 beaufort.

@DouglasHPlumb 6 лет назад

It would have been much better to see more footage at the end. Very cool. Fs ? Second ord pos. control? DSP on controller or do you just run recursion in std micro? Why FG instead of carbon fibre?

@lukasreitemeier 6 лет назад

You are completly right, but I was on a tight budget (so no carbon) and had absolutely no time to develop the perfect controller, so it was kind of the savest cheapest way to take off once...

@Bigal62 5 лет назад

Lukas Reitemeier Hi Lucas, I’m designing a tri Marian utilising adjustable foils. Your electronics look great. Any chance of a discussion on the programming of the module? I can’t find anything on the arduino forum Thanks in advance Al

@MarioJunior09 7 лет назад

Congratulatios! Great!!

@thaiiexpat10 4 года назад

Your vertical controller works like a charm! Nice! You used infared or ultrasound or what to measure distance from sensor to water?

@ariffsyamil1665 6 лет назад

what servo motor did u use?

@lukasreitemeier 6 лет назад

For this test run only some cheap 40 kg servos from china. I expected thise to burn up and they kind of did, but they hold up 45 min just fine. (if they have to hold position under a weight, it is basicly a short circuit.. ) For longer operation a threaded rod and carriage would be better.
