I'm really liking your content lately. As a fellow professional, your ideas, designs and execution are a1. I know it must be a pain to produce all the videos. But you are providing so much value I just want to thank you for all your hard work.
Sure and thanks for the feedback.
@@TechIngredients Hi, I'm wondering if you'd consider looking at some kind of Laser Rust Remover as a possible DIY project. Take a look at something like this:
ua-cam.com/video/ACGSzBXKONo/v-deo.html
I've read that such devices can even work effectively with 50W or 100W lasers, and given their obvious utility for so many things, I was wondering if such devices can even be made as a DIY project.
I wanted to skip to the interesting part...so I watched the whole video.
Nice.
Me too, so I went back and watched all the videos I haven't yet.
Sad. Feel sorry for you.
Comment of the day Sir.
There is so much to learn from this man.
Your proof of concepts are nicer then most people's finished product. Thank you!
met this channel when you was going over jet engines. Thank you for the wealth of knowledge that I wish I had the time to use
Pay close attention, if the world ends soon this stuff'll be handy. There's a book called Con Nuestros Propios Esfuerzos that is also very useful in "the world ended but we still have buildings" type situations.
@@Teth47 but why would the world end though?
Get wet
Haha same thing 😂
So impressed with your flexible and deep thought designs. Thanks to your team!
Seems like you've got more than enough power in the linear actuator to use a much shorter arm on the rudder. Might be worth it to speed up steering response.
its brobably enough for the gasoline propultion but when he puts on a sail all the power will be needed because there are a few effects that can happen i have expierienced one of them in german it is called "sonnenschuss" this effect happens when wind and wave and current hit the boat at an exact angel and then there is a huge force on the rudder it often even breaks it even on larger yachts so i think the arm is good as it is.
I was thinking the same thing and honestly he can have a variety of sizes to suit his propulsion methods longer arm for sailing shorter for engine or electric.
I think what he meant to say is a lot of force, not a lot of power. That being said. I would shorten the arm.
well he could install another axel on the arm further in so the actuator could be connected on either, but then I think he never wants to turn the boot on the spot either :-)
@@snekmeseht yes that is what i ment
I think the boat would be more responsive and maneuverable with a faster-acting rudder actuator.
I’m looking forward to seeing the final product.
Not necessarily, at high speed, a gentle touch is what you need, you definitely do not want the rudder to act as a major braking system and loss of control if moved too quickly.
@@ericdelevinquiere9902 For sailing boats you absolutely want that capability. It's the only real braking maneuver you get with that.
Dunno what it's called in English though
But sailing's not high speed, so your point still stands
@@ilikeyourname4807 Sailing is not high speed? Similar to this boat, think of a high performance beach catamaran, scary fast, now add foils, you would smoke this boat. Let's not even talk about ice boats. And yes, just a minor adjustment of the helm and they turn like a Formula 1.
Just make a clamp with a screw upwards and u could adjust the leverage and test it out...
If they find they need or want faster response, it is just a matter of bringing the pivot on the lever arm of the rudder closer to the rudder pivot.
I remember when you guys had 20k+ subs. Damn. 500k soon. Well deserved. Looking forward to 1M. :) Thanks, Mr. Wizard.
I've been a fan of the Thai long tail from the time I first saw one in the Philippines. Keep things as simple as possible but not simpler, said Einstein. Beauty!
Another great video. You are an incredible thinker-doer. Rare to find someone so intelligent that also can fabricate. Very talented and impressive.
Really well explained. Had no idea how a Thai drive worked - never mind that it works so well - but I do now! Excellent channel. Five stars... again!
Thank you for explaining things in an understandable, accessible way. The science channel of my childhood (90's-00's) *wishes* it had the quality of content found here.
Thanks!
This guy is seriously my hero! I wish to aspire to be: "so cool that I can explain highly technical details in 30 minute videos and even get 6 second attention span millennials to pay attention!"
millennials are like 30-35
If you aspire to be "cool", move to the Artic, that should satisfy you. 🏔️
Thanks for the ridiculous amount of hard work you all put into this channel. Everything you all do is spectacular!
i feel like the rudder system is not responsive enough. but that's just one guys opinion. i feel like the pully system might be a nice removable alternative
That's what I was thinking! And what if you run out of battery power and you still have gas for the engine? Then your boat is uncontrollable! Or what if you lose an actuator due to a failure, then you have no backup if you're out in the middle of a big lake, for instance. A pulley system would be something to think about adding as a reliable backup or as a replacement for the actuators altogether.
Battery could be charged from the motor if it has a charging or lighting generator? but a smaller lead cell battery or gel cell battery may give more battery life? worst case a paddle can be used for steering :P Also if he wants a faster movement of the rudders a shorter throw lever on the rudder can accomplish that, just saying.
@@nyxkeres8597 Well in this case the motor does not have electrical output, seeing as it's a swamp motor. If you would want to charge your battery from the motor you'd need to install a generator on it. And as this motor does not have an accessory gear box, you'd need some construction to build it onto the driveshaft, in between the propeller and the motor output shaft, which would be a pretty difficult task. Not to mention the added weight on a supposedly lightweight catamaran ;)
The boat will be quite slow, so there’s no need for fast response 👍
Electric actuators don’t give tactile feedback to the pilot. Its gonna be harder to “feel” the boat.
This is the only UA-cam channel where I will drop everything to watch every upload. As a young engineer, you are inspirational. Thank you.
Sweet, great project. I wonder if you'll find that linear actuator is too slow to steer the boat fast enough at top speed?
Mike Clarke it might make an interesting video! My uneducated guess is they'll need very little movement in the rudders to steer at top speed.
Yeah I'd like to see how this pans out. I had a similar actuator on a power wheels truck and it was terrible. The worst part is it locks the steering, so if you want to manually override you have to disconnect it.
Way too slow. There is also no feedback whatsoever.
@@firstmkb Yes, the faster you go the less rudder deflection required. But the response time on this system will be very slow. Without feedback you will have to respond after you start veering off course, then you will have to straighten the rudder before you get back on course to ovoid overshooting (which will be nearly impossible). They will be endlessly chasing a straight course.
I predict that they will remove the linear actuators and replace with a proper tiller system using push-pull rods and a tiller, like a typical beach cat uses. It would be equally easy to set up and break down as the linear actuators, and infinitely more appropriate for a vessel that should be able to achieve more than a couple knots of speed.
May end up shorting the steering arm as an iterative step.
Superb content, in such diverse fields. Certainly, one of my favourite channels, watching all your videos. Thank you so much for the brilliant teaching, logical thinking, and so well explained!
You and I are so similar. It's unfortunate that we live on opposite ends of the country, I would have enjoyed meeting you and trading ideas. Love your work!
Fantastic presentation of a superb project from an exquisite channel. This is what the internet is for!
Any concerns with the rudder being so slow? Given boats natural delayed reaction when it comes to turning I feel like this could be a problem area.
under sail you could get stuck "in irons" the large dead zone catamarans have pointing into the wind.
Great fun watching these boat building videos. Thank you for all your hard work. I know you guys are having fun.
Lovely content, as always!
Will you share some of your machining magic at some point?
I appreciate your thorough explanation of every detail
As always, both educational and fun videos. I've learnt much from your channel.
Two questions: how do you keep the two rudders synchronized and not get out of step with each other, and will the rudders respond fast enough for all practical sailing scenarios?
There is no synchronization mechanism, but they can be resyncronized by pushing them to either end stop.
had the question as well. Also, i think that returning the rudders to neutral position is going to be a challenge... all that seems like a very uncontrollable boat.
Technical but very easy for anyone to understand. Excellent job and ill be waiting for the next video. Thank you for all your willingness to share your knowledge and experience.
"We Went Back In Time Because Our Boat Goes Faster..."
Now that woulda been impressive ;-)
They've got to get it up to 88 mph first.
@@outputcoupler7819 - Marty got a push from a train on land.
- on water a helping hand from aliens...ehm.. the swamp-gas
@@outputcoupler7819 Actually they have to live at 88 Moscow road & yes moscow also=88. Doesn't anyone actually know what 88 is from, geez louise this simulation so many built in blind spot programs. Look up HAUHET & HEH who is also called KEK the frog guy from Egypt it's why people talk about Q & QA.... If only people could read hieroglyphs lol oh well maybe in the next run of the simulation you'll improve.

No I don't watch wrestling thinking it's real either but hey you do you right .
Absolute rivetting. I can't believe you hold my attention.
INSANE gap between the speaking volume to the music
03:06 annoying plosive.
Do you need someone to do an audio post-production? I can handle that
ofir.gaash@gmail.com
I suggest they cut the song out, throw up a quick logo and call it a day. I don't come here for the music.
Couldn't get a minute into it, damn shame too.
Yeah, speech volume is OK but music volume should be brought down to match.
Like in every video on the internet or on tv. Why is everyone doing this? Just turn the damn music down pls!
Been a fan for two years now and you guys keep out doing yourself. Wish I had watched since the beginning 🤦♂️ love from Cali
I don't know much about boats but my gut feeling tells me I'd want faster actuators for the rudders in order to get a quicker response, what's your take on control speed here?
We can increase that speed with voltage and by trading force for speed. We'll see.
@@TechIngredients you mean we'll sea
I'm wondering what happens to the motors when they inevitably get soaked...
Tremendeous! I love the real life and reason based approach to solving problems.
One always learns a lot of new things on your channel! I left a couple suggestions for projects on the patreon page! One about a DIY Digital Micromirror Device laser projector (worlds best projector, in addition to the best speakers), and another about a DIY heat recovery ventilation system (a continuation of the climate control videos). It would be very interesting to know if you find these projects feasible/interesting. Many thanks for your great work!
MEMS are crazy stuff, better to buy something in my opinion. Once done with all these other projects lol, i would definetly love more of the Dessicant AC series (perhaps make more modular + contanerized, diy fans, etc) !
i would like to see something liek a full body bio suit. something...sifi ish!
@@ericlotze7724 It sure seems complex with Digital Micromirror Devices, but if it is at all feasible to make DIY project, then it is something on the level of Tech Ingredients team. :)
Nice to see another technical video about the boat.
I just realised that your channel icon was a vinil disc in it's player - I used to think it was a cd smoking a blunt!
It is actually a HDD disk platter with the read/write head. This is what it looks like with the case removed. It is interesting what different people see when they are all looking at the same thing eh?
It's a hard drive. I don't think a record would be a very appropriate icon for this channel, do you? Also, it's "vinyl".
What's interesting is that hard disk technology has changed enough that spinning drives aren't necessarily what people think of anymore when you say hard disk. Everyone understands the meaning of the save icon used in most programs, but a whole generation has been born since 3.5" floppy disks were in common use.
@@peglor Floppy disks and this are two different things. Being born after something doesn't mean anything. Wanting to gain knowledge does. Every computer sold nowadays has HDD's in them. Unless you pay extra for a SSD.
@@flexopuppy If you consider phones and tablets to be computers, which I do given that they are, then solid state memory is already in more common use by more people than spinning HDDs.
On most laptops at this stage unless you only look at very low end ones, you get an SSD by default even on the bottom of the range. Bigger/gaming laptops sometimes still have a spinning disk for long term and high volume storage, but boot from SSD.
Datacentres are probably the last big hold out for spinning drives, and even those, depending on the cost/benefit data are moving to solid state drives.
What I find more interesting is the storage methods that were used really early in the development of computers - this is a particularly unusual example: ua-cam.com/video/2BIx2x-Q2fE/v-deo.html&ab_channel=Numberphile
A really nice project. I will never build one but very pleasurable to watch. Some of the ideas you develop, the way you build things may actually end up in something I make. Your solutions are so neat. Thanks for all.
You're welcome!
intro music sounds like mcgyver!
Too soon
Lasse Lyx - good look
If you mean loud...
Excited to see the motor power output, and maneuverability!
LOUD NOISES!!!!! (plz normalise the audio a bit)
yeah I'm a few seconds in and the just music insanely loud
Yeah, in agreement, loud even for my getting deaf ears.
I have some dynamic headphones and wow that was loud at the start. Far too loud. Made me flinch.
Yeah, the music was too loud
we all know what this is about. there's no useful information in the wasteful first long 6 seconds. i vote for exorcism of the aggression so as to enjoy the meal part right away. OR PEASE REMOVE THE SOUND TRACK OF STRESS during those 6 seconds for peace.
Man, you guys are my Discovery Channel(from back when it was about science and not reality TV)
THANK YOU for sharing your projects with us.
BTW, good job on the new intros.
Love your content but I believe the music volume is excessive.
wHAT????? WHAAAAAAT?? I CANT HEAR YOU!
Yes, it's fun to jam out to. But the talking portion needs to match a little closer.
I wish more video players had Dynamic Range Compression. It's great for bringing the sounds together on the same "level". I know the vlc player can do this.
Yeah, I have to agree. The intro music was too loud, coming from another YT video I got blasted. Then once the intro was over I had to turn up the volume to understand him better.
I've been subscribed for quite some time now, and I have to say that with every video, I'm always in awe of the level of attention paid to the fabrication. I do understand that we may be seeing the result of multiple design and manufacturing iterations, but in any case the quality is top-notch. Hats off to you folks, and I'm looking forward to new projects and videos as they come along!
I was excited that I was one of the first people watching the video. Then I realized I had nothing clever to comment.
🤙🏼
What a good come back from the last episode on this subject, am excited again!
long time listener, first time caller :)
just fyi, it's KNOTS when you're on a boat, not mph or meters/sec.
OK, maybe for you rocket scientists, meters/sec IS appropriate.
you know i'm just teasing :) good stuff as always !!!
Indeed, but it is also good to say as most people don't even know the conversion.
I can convert knots to MPH, but it won't metric in my head. I get as far as 3.6 kiloseconds per hour, then I find something else I'd rather be doing.
I am tempted to slide in parsecs, but there are too many decimals.
@@TechIngredients @Kevin Bauer @wobbly sauce
I humbly suggest we follow protocol; we should go back to fundamental units, such as the ones used to express how much 'ux' is in a Flux Capacitor:
knot-second-mole
per
coulomb-meter^2-ounce
🤔🙄😏😂😂😂
Problem solved :P
The technical information provided are awesome!
INTRO WAY TOO LOUD!!!
Thanks for showing us your cool projects!
Loved the previous version of the catamaran, and could tell from the smiles of the people on board and spectators that it was a lot of fun. However, if you are not laughing maniacally sometimes there is definitely something missing from the boating experience! Greatly looking forward to seeing the new iteration in full flight!
Thanks for the wonderful videos. They are unique in the making explicit the detailed thought processes that go into great engineering design, and revealing how endlessly interesting but rewarding and useful engineering is as a vocation.
Thanks!
We're scientists, we have a lot of self control.😋
Watched when you first built the Catamaran and Enjoy all of your work. Can't wait to see your next video and other projects. Have a Great Holiday Season.
Thank you, I always look forward to learning new things when I watch your videos.
A wonderfully informative and entertaining video once again. You are a shining example of how to make STEM appealing to the general populace.
Thank you a lot for running such an interesting channel. The depth of knowledge in different fields that you show is astounding :)
I replaced an old gasoline engine on my sailboat to an electric this spring. I had just the same type of forward-neutral-reverse switch mounted on a wired controller (not for steering in my case, but for engine rotation direction). But when we accidentally dropped the controller on deck, with the switch taking the impact, it got stuck in neutral, rendering the engine inoperable. Being a sailboat we could go to a sheltered bay and make a repair, but on a boat without redundancy propulsion, or if the boat can't be maneuvered with the switch broken (like if it controls the rudder). It goes to show how much a small little button affects the operation of the boat.
Finally the hydrofoil. I've been waiting since the build video teaser
I enjoyed your update. I'm still waiting for sails!
As an engineering student this is one of my favorite channels, keep up the great work! Side note: "NACA" is an acronym, like ASCII or NASA, so it can be pronounced as a word.
So cool! Need to go and watch the other boat episodes
Great videos, thank you for sharing, looking forward to the test ride!!!
Wow looking forward to seeing it on the water and see how it goes God bless you cliff from Australia
I'm looking forward to seeing how the hydrofoil works. Thanks for posting.
Love the water foil idea!
If there's a better engineering channel on UA-cam then I don't think I've seen it
Very cool!
So interesting that you'd use an electric actuator on the rudders.
I'm looking forward to seeing how they work out.
Looking forward to see it on hydrofoils,
Congratulations for your videos you guys are doing a fantastic work
Great experimental boat. I love these unconventional boat series. Looking forward to seeing the ruder construction.
Fantastic stuff. I really like this project. Hope I can do something similar one day. Looking forward to seeing the addition of the hydrofoils at some point!
phenomenal project. Excellent narration as usual.
Looking forward to see this boat running.....!!!! Hopefully also a footage from on board
I initially started watching the first boat building video because I want to build a sailboat. I'm starting with a scale model, similar to the one you built.
Im fascinated with the direction you're heading.
I'm planning to make a 2 masted boat, one mast in each hull. I'm making a video of it, to be posted later.
Keep up the good work.
Good luck!
Looking forward to the next one about the construction of that panel.
Great video. Thanks. Love the walk through style of design and engineering process. Waiting eagerly for more on the construction.
Awesome, I love linear actuators!
The switch wiring tip is super handy. thanks.
I love your channel. Can't wait to see it running, ive seen a few Thai long boats racing, they are so fast!
You need not worry about having too little details. Your projects are always interesting and you seem to think of nearly every possible problem that we might encounter during the build and as well the operation or function of it. I like the variety too. Even if you do something I am not necessarily a candidate for, I still find it most interesting. Thank you for your channel.
Thanks!
That's why we post them. Not everyone wants to build a boat, but the strategies can be useful.
I am building an electric drive for my 65' live aboard proa with a very similar shaft/prop arrangement. All home built of course. I got a few useful tips from your video regarding the balance of the prop in the water. Thnx!
Good job. I love how you explain everything. I’ve been on a boat in Thailand with one of these. Some of them even use V8 engines balanced. I have seen a few of these in Alaska used to run up rocky river.. On another note, growing up in the 60s my Dad had a cabin in Newark near Center Pond. I fished Bean Brook many times as a kid.
Always happy to see a video from you. Keep on keeping on! :)
"part of the reason we wanted to do this is I thought it'd be fun" words to live by
I use those actuators for web steering applications.
The one I use is the same size, and it produces a maximum force of 500N.
It's perfect for working a rudder, they also do not back drive, so when you let go of the steering, the rudder will stay where you left it, and therefore you will be able to trim the boat straight very nicely in a crosswind.
Nice video and project, I like it.
Kind regards,
Duncan, South Africa
Great work! I can't wait to see how it preforms with the hydrofoil! That is going to look really great in the water! :)
Just a thought. It may be easier to navigate if you wire the double throw switch transverse at the top of the bar, removed from the potted driver assembly. Then again, your thumb may have greater range of motion offset from the central axis of your palm. Anyways, love your content as always. Best engineering channel on UA-cam, can't wait till you guys cross that million sub count.
Again, you're causing my brain to thrive. Thank You.
I'll most surely never build a boot, but I like how you always think through every detail, I learn so much and at the same time it's so entertaining. One of the channels I never fall asleep watching. :-)
Are you Canadian?
”boot” 8-)
Great episode as always! Loved it!
Yeah the lightened aluminum looks dope. And I always wondered about those Thai boats. Another question answered by this channel that I wasn’t expecting to ever be answered. There’s only one problem with this channel. There isn’t enough of it!
Great content as always, thanks! Personally I would love to see you dig into some of the engineering calculations you would do for this type of thing. I also wouldn't mind seeing your approaches to machining some of these things as well. Keep up the great work!
Blows my mind and leaves me smiling every time I watch your Flicks. But I think its time to trust your audience and admit that your a retired astronaut.
Very interesting. Looking forward to the next one.
This guy is my hero! I cant wait to see the new mods in the field (water) didnt realize you were in VT, getting brisk!
I had a few awesome "shop" teachers but you are top notch.
Thanks for the awesome video-
Keep 'em coming. Love the boat videos
Fantastic work! Thank you for sharing.
Very thoughtfully done!
Ready for the test of this design. Wish y’all could get these out faster! Your videos are awesome.
Interesting build! Now lets see more composite stuff!! I'm waiting on that ultrasonic homogenizer!!! Keep it up guys!
Another great video...I feel that one would anticipate needing more control of the prop's tilting angle after coming up on the hydrofoil's plane. Can't wait to see it on the water!
It's always a good day when it's turtleneck day.
I look forward to part two...cheers.
I like the walk-through of how everything works, but I'd also be interested in seeing your the design and manufacturing process as you go through it, in addition to the finished product
The extended shaft boat motor, like the outboard, is an American invention. Calle was mass producing them more than a hundred years ago. Long before Thailand ever saw an internal combustion engine. The link below is a video of a 1925 Calle Liberty Twin in action.
In regards to your steering control, there is another option that you didn't mention: push-pull cable. They're available in numerous sizes and load capacities, and can be quickly connected with a clevis. Unlike your current binary control, a push-pull cable permits full proportional control with feedback. This is something that you will want as you go faster.
I'm not a big fan of your single asymmetrical rudder. So far, you've only achieved very low speeds, so any inadequacies in your steering system haven't been a problem, but as you go faster you will not be as happy with your current arrangement. A simple tie rod can be used to connect a second rudder to the first.
