Sail Life - More digital switching & making Obelix shine - DIY sailboat

Publicerades den 21 mar 2021
Good old Obelix needs a bit of cleaning before being ready for sale. In this video, I scrape the bottom, polish the topsides and apply fresh bottom paint. Aboard Athena, I install more czone digital switching boxes and get an annoying surprise.

  • Great work Mads looking forward to your journey over here in Scotland. Have you any thoughts on the E-Plex digital switching ? I have been left a set but don't know how to get hold of the software, can you give me any pointers ???

  • My Sunday Is once again complete see you

  • Man, whoever buys Obelix will be getting a great deal. So inspiring 🙂👍

  • We are ready 😅 did you change also to summertime ?

  • me and my little brother love the videos but my brother wants to know what is the song called when you lift obelix out of the water! thanks

  • Where is the dog? Isn't it time to get him on the Athena?

  • Great progress!

  • dame spifffy

  • I feel your pain. For some reason my engine compartment light decided to start screaming a month after installation. Why does this happen?

  • Mads, I have the same Bosch polisher as yours but cannot find the large size disk/sponges/sheepskin . Do you have a reference website? thanks

  • One for sale; the other, for sail!

  • Great episode as usual. Been watching for about two years now but have binged watched all episodes . I couldn't imagine a sunday evening without your show. Just wondering, haven't seen your dog for awhile how is he doing? I am sure he is ready to move onto athena also.

  • You may be able to put some kind of noise filter on the line feeding the lights. You would need to find out the frequency of the noise and someone could easily make a filter with some simple electronics. If you have a trade school with an electronics dept., one of their students could probably build something as a class project. I went to school for electronics but it has been many decades.

  • Thank you for the wonderful music in your timelap. It's added to my person's playlist. Great work Mads, I love following your project..

  • May lightning never strike your boat

  • Nice Job!

  • hahaha I thought that was a USB powered kettle at first glance!

  • You really like you digital gadgets !!!!

  • Aren't you supposed to wet sand antifouling?

  • Your workmanship and work ethic is amazing!

  • God Oblix looks beautiful. I think her new owner will have a lovely boat. Wish I had the funds

  • Those Renskib products seem very good and if I can ever get to my boat this year; And if they are available in Greece I will give them a try. I wonder how many others of your 91k subscribers will also seek them out? Suppliers take note........ The power of sponsorship!

    • @H. Kirk I am more than happy with my technique and whilst Sureholds 'buff magic' is pretty good start to the process I feel their final polishes could be better. I will certainly look out for Renskib in Greece and give them a try if I can. The last time I payed someone to polish my boat I made them do it again - It wasn't good!

    • ​@H. Kirk Greece to Denmark for a boat clean......Let me think about that..... No, I don't think so. Alas, my yard has also started to charge by the week for taking in parcels so shipping from Denmark would be an opened ended payment until we are all cleared to travel again. I have been using surehold for a few years but getting that shine is not on the cards with their detailing solutions.

  • with thinkpad notebook maybe X series thinkpad...you must be a network engineer....I see a lot of networked equipment on your sailboat

  • When you through up......the nasty tast in your mouth is hydrochloric acid.......so it is not really something to be afraid of. It is generated in your stomach. Like the finish! Good job.

  • When done the boat will automatically make coffee when you turn on the light in the morning 😄

  • The LED hums for the same reason I do, I don’t know the words

  • 7:51 Now I'm wondering what bivalves get recycled into.....

  • Keen to know more details about the Antifouling paint

  • I’m worried Mads. You appear to be getting stuck into the enjoyable geeky stuff but not the things that a young lady on a boat will demand: A door for the head, a head , a shower, hot water a working sink, A MIRROR!!! I know these things will be mega important and that she will not be impressed if the lights work from 50m but there is no mirror. Just sayin, you have been warned!!!

  • Thanks ... LOVE your sense of humor. Each episode is so crisp and informative. Strong work!

  • Wow fancy having to go to all the effort of finding and then pressing the remote button when returning. Surely a gps fence can be setup so your phone location can trigger lights on? Totally hands free, although remembering to keep the phone charged may be a pain.

  • Adding my two cents to the million comments here about humming LED's when dimming: We had an LED circuit that only started humming when all the bulbs were in. One bulb: quiet, smooth dimming; multiple bulbs: humming, flickering mayhem. We found and LED that was compatible with the dimmer and problem solved, but in other areas we skipped the smart switches due to compatability woes. Not sure how smart your smart switches are, but is there a "play dumb" setting? In other words: only full on or off, no gradual dimming, always pulsing nonsense. As others have suggested. One simple solution is a filter in line with the LED's, or make your own with a capacitor/inductor. Good luck, and nice work.

  • Could they be humming because of operating voltage or because of the led controller or something else? I am no expert, but do some research before replacing all of them.

  • HI. Regarding the problem of the LED light being too yellow, there are many kinds of LED lights. You can choose 3000K 3500K 4000K when you buy. The larger the value, the whiter the color. In addition, for some personal opinions on the circuit on board, I think I like simple switches. Circuit or LED DC dimming circuit, maybe your current digital switch will be more advanced and more convenient to use, but I personally doubt its reliability. I am a relatively conservative electrician. The simpler the circuit on the ship, the better. The number of relays and digital switches should be reduced to a minimum, and attention should be paid to lightning protection and waterproofing. When danger occurs, the simpler switch may play a key role. I am very interested in your boat, and I want to know how long it is. Your handwork is great, I like it very much, English comes from Google Translate, Peter China

  • All the fancy electronic relay controls are really cool but can you manually control everything if your box fails?

  • Obelix boat is yours?

  • man i sorry this old man doesn't count on wifi i would rather use switches

  • Clap On. Clap Off.

  • Oxalic acid is my favorite chemical for cleaning. Locally in the U.S. we have a product that contains the chemical called Bar Keepers Friend. It's very cheap, it works and it's carried in almost every supermarket.

  • Iiiih hvor tilfredsstillende at se på 😁 min kone og jeg ser trofast dine videoer hver søndag 😁

  • Find the LED that doesn’t hum. Then look at theatrical gel sheets. Something like CTB or CTO, depending on which way you need to adjust the color temperature.

  • Hi Mads, where is your dog?

  • An Oxalic Acid tip: Mix using Wallpaper Paste, it sticks to the hull and works faster/longer, but still washes off.

  • Great progress, thanks for sharing

  • Does the lighting controller offer different PWM frequencies? That would probably remove the audible hum

  • I don’t need boat products, but if I would I’d trust your recommendation or the general products you use even if they sponsor you, you take so much time to find the best solutions for you if you use something you invested quite some time with checking if it’s any good

  • What a sweet red VW T3 at 13:53! 😍😍😍

  • Yay we have a Spiffy, I was starting to suffer from withdrawals

  • Hi from Sydney, the bottom cleaned very easily. Do you know if TIVOLI GARDENS still going i went as a kid in the 60s as my mums brother married a Danish lady and Dad took me to the Carlsberg factory and through the canals in Copenhagen.

  • Hello, About Obelix antifouling ... we have very good experiences with cow teat ointment. That is very thick fat and will last for years. It hardly produces growth. I think the last time we applied antifouling was 6-7 years ago and since then every time the boat leaves the water we smear a layer below the waterline. That is good for the environment and the teat fat is also very cheap. www.deonlinedrogist.nl/bogena-uierzalf-700gr-p-4119.html?channable=0017936964003431313965&cross=0&.

  • Great video as usual Mads. Thank you.

  • I sometimes think that the recycling thing goes a little far. Sure dumping rubbish into the sea is a big no no. However putting marine creatures back in their environment would seems to be a good idea! I mean what is next all those fishes are making the sea dirty lets take them all out!

  • It could be that you did test your LED's there could be multiple reasons for them to hum like they are happy to be aboard :) Another reason could be that they are part of a different inferior batch. Not a thing you can do about either however one major variable you can check is the installation the cable run and the power supply is certainly different from when you tested them. Obviously you do not want to spend a lot of time/money on this problem. But dismount one of the installed ones just hook it up to a battery or however you first tested it. If it still hums well back to the drawing board if not than maybe some sort of voltage regulator or some way to clean up your power supply would do it.

  • Hej Mads. Det er ikke nødvendigt at bruge så kraftige midler som oxalsyre. Det er nok med toiletrens, smør det på lad det trække i 10 - 15 min og vask det af. Jeg ligger i Roskilde og vi har rigtig meget af det stads. 😊 Niels

  • How about some protection from lightning strikes? think you will be needing with that amount of electronics. Love your videos.

  • 👌🏽💥🤛🏽💯⛵️ dang spiffy video.

  • Great job man! Can you please remind which model of Bosch GAS is that vacuum cleaner of yours? Tried to look back through your videos but could not find out when you got it. Thanks

  • The first part of this video is a prime example of what you get when you have a computer geek do a sailboat refit. And I love it!

  • you inverter could be the cause of the humming if you are plug on shore??? I know some inverter make noise it the electric signal. or a motor messing the signal.

  • Great Video Mads!

  • The software engineer in me is geeking out on the electronics setup. The sailor in me is thinking, one lightening strike (or near strike) and KABAM! … all is toast.

  • You should get a double coil kettle, most cheap ones use only one coil, hence why they're so slow.

  • LEDs hum when they're on a dimmer circuit. You don't have to search for another LED, you have to find a better dimmer, or, perform some EEV magic, and use a hard stepped dimmer (i'm not sure that's what they're called) essentially, something that steps the voltage with physical preset levels. It's a bit bigger than the cheap or super expensive variants, but it's used for stuff like that. Two other things: 1. unless you were on dimmer switch when you tested them, that's why you didn't hear them. 2. are those LEDs rated for dimmer applications?

  • Good to finally hear of someone talking about Oxalic acid to remove the tannins on a gel coat, you can buy this crystal form at a lumber yard and it is called wood bleach, very cheap and yes it should be put on with a brush because it would be in the air if you sprayed it on.

    • @David Richards Thanks for tips.

    • Only be careful with any painted surface because the acid can eat it right off the gel coat below... test a small area first.

    • Good to know about, fo my future project too.

  • Hello from Ontario Canada, Obelix hull looks AMAZING now! I’m wondering about your LED lights, you mentioned the hum and that they are able to operate on 12 and 24 volts. Have you tried them on 24 volts to see if they are more efficient and therefore quiet at that voltage? 24 volts is apparently a better voltage on live aboard boats or so I’ve heard. Don’t take my word for it, I’m only an insulator not an electrician. Cheers Mads!

  • Obelisk looks fantastic! I Wish you could ship her to Texas.

  • Is it just me or did your lights actually dim while you were talking about the humming lights. They seemed to have a mind of their own. LOL

  • The technology you are putting into Athena is really cool. However, sailboats being hit by lightening is not that uncommon, and many find it ruins a lot of the electronics onboard. Since your system pretty much runs everything but the toilet from your central controller, you could be in a world of hurt if Athena is struck. I hope it never happens to you, but might be interesting to the viewers if you talk about how you are guarding against loosing all of your systems should you be struck by lightning. I love watching your videos!

  • Obelix looks great (and small !!). Well done!

  • I have actually found (from the personal experience of cleaning a bronze prop that had been submerged for years and was totally encrusted with barnacles and other shellfish) that plain old white vinegar did just as good a job as Hydrochloric acid, and was MUCH safer to use. (not to mention really cheap!) worth considering for the future.

  • since you've got the keyfob thing, might as well install a keyless lock on your companionway, right?

  • Think you are going to need a PWM dimmer/switch that switches above 20khz, ceramic caps acting as piezo speakers.

  • Nice video

  • Obelix will be in great shape for the next captain!

  • The humming is caused by the driver...usually because of too much load

  • I may be showing my age, but what is the problem with just a light switch.

  • Any chance of an expenditure update on Athena?

  • Mads- Your LED problem is likely NOT the LED but the type of dimming. Dimming can be done with a Pulse Width Dimmer or analog. PWDs dim buy turning LEDs on/off rapidly and are cheaper and the voltage clipping sounds like a hum so my guess is you have a PWD. Do some research for a good analog dimmer. These reduce current to reduce to the LED. Dean PS- Love your channel- an inspiration for me doing a major refit on an Orion 27,

  • Oh Mads I love your channel but after 2 minutes of electronics my eyes and ears were starting to bleed!! Thank God for warm weather and Oh Glorious Sanding!!

  • Obelix looks like a million bucks.

  • LEDs are physically not capable of humming. It is always the dimmer or driver modules that are the problem, fyi. Shielding those modules and putting ferrite beads on the wires to/from them may cure it. That can be a tedious hunt, best to contact the manufacturer or an electronics tech.

  • Assorted Seafood!

  • I am just here for the glorious sanding.

  • Obelix is looking sharp!

  • I hate the idea of hauling bags (practically unrecyclable single use plastic) of barnacles to the "recycling" center instead of dumping them back in the water where every critter that eats barnacles lives. Heck, if you were quick plenty of the animals that you scraped off could survive!

  • Your Oblix is looking great, we have to do the same here soon to get her ready for the summer.

  • Having sold three pocket cruisers and now owning a fourth, when they get all cleaned and detailed you get second thoughts on selling them... haha, but I did! Mads, Obelix looks terrifically spiffy!!! ⛵😁

  • I'm here for the "Oh glorious Sanding" OMG, your killing me with the puns! ROFLMAO

  • Thanks! Great episode. Can you provide links for the digital switching? I want to go down that road. Obelix looks fantastic!! If I wasn't in Canada, I'd be interested in submitting an offer.

  • I love the tech I have a smart home addiction so I can relate. Very nice to have the gadgetry on the boat can't wait to see it all up and running. Athena is really coming along nicely Thanks for the peek into the systems on board..

  • Question: “Why are the LED’S Humming?” Answer: “Because they can’t remember the words to the song!” 🤣😂 😎

  • Nice job! It is so nice to see a DIYer complete projects in such a professional manner. So many channels do work that is subpar.

    • I watch way to many YT videos on a regular basis. Most of the boat channels I watch do a very thorough job (wooden and fiberglass) a few steel boat channels not so much, maybe because grinding and filler is cheap not sure. Many YT channels do work that isn’t up to my standards.

    • That was a sweet thing to say about Mads yet for all those others SEnewss creators out there? Not so much.

  • Obelix looks really good for a girl my age. I think Ava would love ❤️ disco mode lighting. I can imagine her dancing around the cabin giving you a big Mads smile. We are going to have a soundtrack, right!

  • Maybe I need to be reminded yet again, what is the point of all the technology just to turn a light on/off. I can’t see the advantage, yet I see multiple disadvantages. A lightning strike may not be a happy event, yet a quite common event in my sailing area.

  • The led and the dimmer must be compatible, there are different wavelengths that an led can be. Just make sure you match them up. A company named Imtra informed me of this while installing new lights on a pacific mariner 65

  • What will you when teck goes down

  • Where is Yurkle ? He is a cutie.

  • It would be interesting if you would talk about the reliability of all this high-tech electronics and what happens when a box fails and you can't turn on the lights and the Amazon delivery truck with replacement parts is far away from your anchorage.

    • @Scramasax Mads showed a few weeks back that if the switching box fails each circuit can be energised by shifting a small fuse in that circuit inside the box so its not the end of the world if this system fails. Though for my mind I can't understand why such high tech is needed to switch on lights and keep it simple stupid is the safest way to go when on a voyage. But each to their own and as a project it is always very, very interesting even if not agreeing on some desisions.

    • Maybe the quality is just superb and they never break, but today when everything comes from China... I don't know about that. I would try avoiding to connect anything vital into this. Anyways, fancy stuff just something not for me, a guy that dimms a LED with a resistor.

    • It is what it is Gene. I know of no more qualified person to MacGyver a system until parts arrive. To talk about all that which might happen is best left for a later discussion over Piña Coladas in the warm pouring rain.

  • Great episode!

  • Great video.....I still wince at the computer control of everything..lol...LED humming is sometimes a current issue, check to see what the max current your relay circuit can drive against what the current draw per LED is.....just a thought...be well...John
