- Опубліковано 20 бер 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.

Thanks ... LOVE your sense of humor. Each episode is so crisp and informative. Strong work!
Your workmanship and work ethic is amazing!
Hi. I usually do not write any comments on the videos I watch in You tube, but I have taken the time to write to you because I believe you are amazing. I have been watching all of your videos since you started your refit on Athena and it wasn't until today that I finally caught up with the weekly videos. I have learned a lot and you have motivated me to finish all the small jobs on my boat. You're ingenuity, your preciseness, your constant attention to details, your pursuit of making everything just perfect and not just doing okay have made love your videos. There are not too many people that actually read the instructions, follow the manufacturer instruction, nor take the time to contact them for further instructions and ways to do it, and you are one of them. I can mention hundreds of times I was amazed of the attentions to details that you had in doing something in Athena, but the list would be too long. Before I go, I wish you all the best, and thank you, thank you, thank you, for inspiring hundreds of thousands of people around the world. Hope to meet you one day if you ever go to the Caribbean.
Great comments which I would like to echo, besides the Caribbean part 😜
I have found the extent to which Mads just "keeps on keeping on" is stellar. I quit complaining altogether about the amount of work I have yet to finish on my cargo trailer conversion. I am humbled by Mads actually finishing everything on his list. My list? Not so much.
Thank you so much! You're very kind! Your comment brought a big smile to my face :) Fingers crossed our paths cross in the future :)
If in fact you do go 'DOWN' to the Caribbean, don't forget to install a A/C unit. You'll need it! 🏝= 😰 and lots & lots of fresh water.
Obelix is indeed looking quite fine. Whoever gets her will have a well loved boat. You are taking more care in preparing her for sale than some do during regular maintenance. Well done.
You have been part of my sunday ritual for years!
Haha same.
Same!
It's funny cause I have recently been thinking the same!
Same

Obelix is a hot candidate for the yet-to-be-founded UA-cam museum of famous items. Don't sell her too cheap!
LEDs can have a low buzz when installed with a dimmer, if you connect them directly with just a on/off switch , the buzz disappears. That's why you maybe did not notice it while testing.
Must be the built in voltage converter...
You may be able to defeat that with a simple filter. A capacitor/resistor pair tuned to cut the buzz frequency. Most dimmers are putting out a simple square wave that varies in total time on. All you need do is trim off the sharp edges of the on a bit. But the ones Mads has may make a little pop when they turn on regardless. But it is a cheap solution worth a try.
Yeah but just use a capacitor resistance ckt to filter.
One lightning strike and all that digital doo-dad could be fried. Then, no lights, no joy. There's much to be said for simplicity, especially for simple (binary) things.
So I would (unsolicited) recommend some backup LED's etc, wired the ould fashioned way - to a battery through a toggle switch :)
Absolutely lovely work overall! You are an inspiration!!
What a sweet red VW T3 at 13:53! 😍😍😍
Man! You got Obelix ready for sale quick and easy! I can't wait to see the rest of the videos and watch you get Athena ready for sail!
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!
Mads, also check to see if you are getting interference with your VHF radio or AIS transmitter. The US Coast Guard has issued a bulletin about some LED products creating enough electrical noise on VHF frequencies to potentially interfere with AIS transmission and VHF for emergencies.
An Oxalic Acid tip: Mix using Wallpaper Paste, it sticks to the hull and works faster/longer, but still washes off.
Omg Oblix has never looked smaller then when you're standing right beside it
Question: “Why are the LED’S Humming?” Answer: “Because they can’t remember the words to the song!” 🤣😂 😎
Obelisk looks fantastic! I Wish you could ship her to Texas.
I had a good chuckle when you mentioned selling the 4 bags of seafood. Great sense of humor Maddy. Obelix is looking handsome and a lucky buy for someone. Salute and greetings from Delaware.
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!!
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..
God Oblix looks beautiful. I think her new owner will have a lovely boat. Wish I had the funds
I've just broken my leg. Thanks God this channel exists to distract the mind and ease the butt soreness from being in bed. Wish I could buy Obelix.
Broke two ribs a few years ago and watch all his videos twice!
The fizz of the barnacles was rather satisfying. Obelix looks amazing for her age, I envy the fellow who gets to sail her next.
I used every imaginable LED in my 2005 trawler. None of them made me happy. I removed and installed with Acegoo RV Boat Recessed Ceiling Light 4 Pack Super Slim LED Panel Light DC 12V 3W Full Aluminum Downlights, Warm White (Silver). And then removed the old light switches and replaced with PCS Electronics, 12 Volt DC Dimmer for LED, Halogen, Incandescent - RV, Auto, Truck, Marine, and Strip Lighting - Long Shaft - Black- I am thrilled with the results.
Mads I hope you reinforce your lighting protection , with all the nice stuff your putting into the boat I wouldn't want to see any of it effected by a random light strike ! It all looks amazing just like a techie guy has yourself would do !! Thumbs UP !!
I told him. ⛈
Now, did he listen?
In a bad electical storm the boat doesn't even need to get hit for things to go bad, kinda like a natural EMP. I've heard of having to disconnect the batteries to keep them from setting the boat on fire.
From my limited research, it seems it's very hard to get some hard data as to what works and not just what's claims by manufacturers. We're not prone to a lot of lighting strikes around here so there's plenty of time :)
@@stevenr8606 That's funny!
Obelix looks great (and small !!). Well done!
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.
Obelix certainly looks super spiffy Mads! I also think it is great that you have put so much time and attention into preparing her for sale - it is a pity that more people do not take the same pride.
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..
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.
That was a sweet thing to say about Mads yet for all those others UA-cam creators out there? Not so much.
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.
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!
Good luck with all those gadgets on board personally I like to keep things as simple as possible. The salt environment and electronics are not good friends but I hope they work for you.
I am just here for the glorious sanding.
I know one thing Mads if I was looking for a used boat I would want to buy yours! You go way above the average person getting something ready for sale!! Well done.
I believe putting a capacitor in the circuit will eliminate the hum. Below is correct, dimmer LEDs must be installed to avoid hum. They have some sort of capacitor installed that stops the humm. Odds are you are not going to hear the hum while traveling and I doubt you will hear them over the ocean.
One for sale; the other, for sail!
Good to see there's no osmosis on Oblix after 50 years, I've an Albin Express built in 1980, looking forward to at least another 10 years of a blister-free bottom :)
Obelix looks really good for 50. My 46 year old C&C looks considerably shabbier.
Just a hint that I used on several boats in the past. Easy-Off oven cleaner removes barnacles and rust stains like magic.
It will even remove the painted name on the bow or transom if left longer.
Good luck in selling Obelix.
Thanks for sharing.
I believe that the reason we all love UA-cam so much is because in 18+ minutes we can get so much work done… and by we I mean You Madds. Great job. You not only worked your full time money making job but also your full time money sucking job… Oblix is beautiful! The next owner is a lucky sailor!
Obelix will be in great shape for the next captain!
You are a DIY boat work Master , You make it look easy . Well Done Skipper!
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
Always look forward to your videos ... first class workmanship
Obelix looks like new! You should not only be confident but proud. The new buyer will be happy. Cheers and as always... thank you for sharing brother!
Obelix is looking sharp!
Yay we have a Spiffy, I was starting to suffer from withdrawals
Pretty dang spiffy. I couldn't put it any better. The new owner will be thrilled.
humming LEDs are bc they're not "dimmable" - you have to get "dimmable" LEDs AND/OR a "controller" that is dimmable..... unfortunately "controllers" are for line AC voltage I believe. anyway hope this helps... oh btw I prefer 3,500 Degrees Kelvin for bulb temp...
Obelix is certainly looking dang spiffy, good job Mads!!
Your Oblix is looking great, we have to do the same here soon to get her ready for the summer.
One of your funniest videos in years. We smiled the whole time. Nice Mads.
Wow, Obelix looks GREAT! Gonna make her next owner quite happy I suspect!
When done the boat will automatically make coffee when you turn on the light in the morning 😄
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,
Mads have you considered the effect of a lightning strike on your electronic systems. It may not be that frequent in the Baltic but if you go to the Gulf of Mexico or Carib. thunder storms and squalls are more common.
He'll be up a shite creek if he doesn't have backups. Have eat his food cold, no lights, no heat, no navigation......
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 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.
@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!
The dimming is accomplished with something called pulse width modulation or PWM. If the PWM is a harmonic frequency, then you can hear it. If the controller is robust enough, this may be configurable.
Check the setting and see if there is an option to change the PWM frequency. Higher frequency will hum less. You can tell if it is the PWM frequency by powering one light directly and seeing if it hums.
hmmm, yes & no - the humming will be from the regulators on the LEDs themselves as it seems to be there when they are at full brightness.
I would hope that Garmin will have taken a little more care over their rfi (and afi) than the LED manufacturers.
P.S. harmonics are multiple of the fundamental frequency, so the humming will unlikely be a harmonic, but the fundamental frequency of the on-board regulators on the LED modules
Harmonics from LEDs or other switching transformers or power regulators etc *can* cause rfi which can knock out AIS & GPS receivers
@@guy.h Full brightness may just mean a duty cycle above 80%. I'm not very impressed with the garmin system for the price point. Also, his lights are not factory LED. He changed the bulbs for drop in replacements. Those don't have any regulators, they just add bulbs in series on the board until the hit the voltage drop they want.
Things are moving fast now, feels like you have some good momentum going! You'll be sailing Athena before you know it!
Couldn't help but wonder if you could have the light switches glow red when the lights are off and turn off when the lights are on (which would be convenient if you were entering a dark boat.) You've probably thought of this and ruled it out for good reason, but I was just curious.
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.
Good to know about, fo my future project too.
Only be careful with any painted surface because the acid can eat it right off the gel coat below... test a small area first.
@@olumjumi Thanks for tips.
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.
Pretty Dang Spiffy indeed ... well done !
The digital switching certainly is an interesting topic! Glad you're covering it. Btw when showing something on the computer, you can use the free software called OBS to record your screen directly so you don't have to point the camera at it :)
Dang Obelix looks awesome. If you want to sail her to California I would be more than happy to purchase her. 😁good job getting her ready.
I know, I know, I know, the water was off in the marina, and this more a comment for other viewers anyway, but: If you can at all avoid letting the boat sit on the dry, always pressure wash the bottom right away while it's still wet after craning out, all the nasty gunk and growth will be sooooo much easier to remove.
Obelisk is really looking spiffy. You did a great job when you did your rebuild and it is holding up well.
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
Imagine you are returning to your vessel by dingy in a crowded anchorage at night. All you may see are 50 mast silhouettes with anchor lights. It therefore might be hard to find your boat at anchor. Can you remotely turn on some special lighting allowing you to quickly identify your vessel? Maybe the emergency strobe light at the top of the mast for 10 seconds.
Sounds like you have a stray frquency transmitting through the 12v system you should look at choke or frequency filter.
Some of my 120v LEDs hum when in parallel with another one. (Kitchen lights.) when I unscrew one, the other stops humming. I don't know about electronics, but is this a clue? I hope so! I find the noise really irritating. I bet a lot of calls to suicide prevention are caused by humming LEDs.
You really like you digital gadgets !!!!
Your pretty good on the maraca.
Okay... That is a spiffy cabin and external lighting system.👍🙂
I'm here for the "Oh glorious Sanding" OMG, your killing me with the puns! ROFLMAO
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.
Lovely lines on obelix.
Which button did you push ?
"Your mission Mr Mads, should you decide to accept it is to make Obelix look new again 😉
Your boat looked marvelous with your cleaning and waxing.
You can use other switches - the signal is either high or low, the rest is software. It's quite fun programming your own setup and adds a uniqueness to your end result. Well done.. Obelix looks good.
Great job on Obelix! Back-breaking job but the products you used (and the spiffy sander) looked good.
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.
OMG Mads, you don’t go for the KISS way of running your boat😳😳
You might want to consider a manual override for your old I interior and exterior lights in case of emergency where your digital switching doesn't work
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!!! ⛵😁
As always you have made my Sunday once again. Thank you Mads 😊👍
Mate, you make it all seem very simple.
Great videos.
The hum may be coming from the LEDs but it's really caused by the dimmer. It must be doing Pulse-Width Modulation (PWM) at an audible frequency. I'd hope for what you probably paid for the dimmer they'd use DC dimming but apparently not. You could stick a sufficiently large capacitor on the output of the dimmer to eliminate the effect and also prevent flickering on-camera.
I couldn't say it any better myself ... Obelix does look pretty dang spiffy, especially being 50 years old!
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.
The humming is either bad ballast on the light, bad grounding in the circuit (only takes one) somewhere, or wires crossing over a higher voltage and not enough insulation on the thinner, led wire.
Hi Mate Good job on Obelix the hull cleaned up very well I got a few of good idears thanks.
Cheers Rory
Love your video o glorious sanding
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.
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?
Nice job on the hull .Impressive ,hard work pays off.
Obelix looks great! Good job. Take care & stay safe :)
Do the LEDs hum when run directly off the battery? Could be due to the digital switching using a pwm controller for the dimming?
I was thinking the same thing. His test were probably done on the 12v battery and now that they are on a pwm circuit, let the humming begin.
That’s a seriously impressive electronics suite you are installing Madz and if nothing else you may have secured a future consulting income stream, should you ever sell Athena.
Obelix is absolutely transformed both inside and out, impressively quick work by you (and Mum & Dad) and whoever buys it is going to acquire a very sound vessel indeed. Above all, they will know how to turn the lights on and off.😉
Keep up the spiffingly good work.😀👍⛵️
Well at least the guy looking at oblix won't want you to haul her out to see the bottom. Also a good time to get a survey if he wants one.
It's not common to get surveys on smaller boats here :) I told him about the only real weakness I know about with the Albin Ballads (mast step truss). He had already read about that online and he had a long list of questions :) It felt like he had done his homework! I think he'll take good care of Obelix if he ends up buying her. He's coming back again later this week to see the interior.
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.
