- In this video I got to install an overspeed controller and fix a broken weld on the wheel. the controller is very simple. it reads the speed of the wheel via a proximity sensor and triggers a really if it goes passes a set value. that then drives an actuator that pulls out a pin and shuts the water off.
It takes great integrity to show what you're not proud with. Seeing both the good and bad makes these projects far more interesting to follow. Unlike some overproduced, cherry picked fairy-tale that gloss over all the bads just to look good.
Thank you.
Exactly! 👌🏻
True.
Absolutely! 👌 Incredible as always Kris. Can’t wait to see more on the barn!
When you are getting paid the best thing you can show is honesty, that includes being realistic and accepting own mistakes.
Well done for showing your mistakes! Weld fatigue is the cause of a massive percentage of structural failures, so it's always interesting to see another real world case study. The failure is somewhat unsurprising, given that at 1.5kW and around 10rpm, the torque generated is some 1400NM, and probably higher given the efficiency losses of the generation system. Additionally, the diameter of the wheel makes for quite a bit of leverage, so the plate that suffered from the weld fatigue is having to resist any forces acting perpendicular to the rotation of the wheel (e.g. from water landing in the buckets at a bias, or wobbling of the wheel from side to side as it runs.).
On top of that, the weld that failed would be quite a low fatigue class, with the closest match probably being class 36, meaning that it was always susceptible to fatigue failure under cyclic loading.
Given that it's been running for about 2 weeks, at an average of 10RPM, it's only seen around 200,000 cycles (complete turns). According to the SN curve for a class 36 weld, that would suggest that the direct stress seen by the welded plate is in the region of or above 100 MPa - a number far greater than would be generated by just the torque alone. I'd therefore presume that the main cyclic loading is coming from the wheel "wobbling" from side to side as it runs, causing the welded plate to flex continuously.
In order to alleviate this, I'd suggest some triangulation braces (perhaps 4, one every 90°) running from the outer perimeter of the wheel back down to the hub. Even at quite a shallow angle, these would provide a lot of stiffness to the structure and prevent the hub plate from being flexed as the wheel rotates.
🤯uhhhhh..........Uhhhhh........ Yeah. What this guy just said.
Engineer?
What book contains this magic you speak of, sir?

I am so jealous of this customer - having a river to produce electricity from would be my dream but to take advantage of it with such an amazing waterwheel... well, if ever I buy a property with a river, I'll be calling on Kris to build me one.
What a completely honorable tradesman! I bought 3 "Made In China" heavy-duty automotive tools over 4 1/2 yrs. and they are all junk. I now NEVER buy from China, not even casual shoes. The quality of workmanship of any Western European, British or United States manufacturer far exceeds that of China or any Asian country. Kris Harbour is a tradesman of remarkable talent, patience and fortitude. Thanks very much for all 5 episodes which took a ton of time to film and assemble into a remarkable TH-cam video.
I like your overspeed failure shut off system!
One useful component for such systems is the cheap electromagnetic door "lock" device normally used to hold doors open or shut. You can get these cheaply in all sort of voltage ranges (AC & DC) and they have huge holding force for tiny amounts of power, and of course, when you remove the current the electromagnet is not a magnet so they are intrinsically fail safe. In this case, the sluice blocking gate could have been held up by such a magnet, and released on either a loss of system power or an overspeed event. This is far simpler mechanically than the chain and pin system so there are less ways it could fail to operate 🙂
A 1 year review of the water wheel would be really interesting next January if you can do that 🤞
Great project and great outcome 👍
Like I always say the kiss principal( keep it simple stupid) that was a brilliant idea. I love it.
Been missing your videos man! Great to see you back. Can’t wait to see some barn updates.
It’s pretty cool to know that Kanye West is watching as well.. 👍🏻
What he said...
What I love about your water projects is you keep things as simple and straightforward as possible. It seems like so many inventors/makers try to make things as complicated as they can. Then it’s hard to understand and I would imagine, hard to execute. Your solutions are simple, doable, and much more sustainable over time because of that. Truly a pleasure to watch and learn from.❤️🤗🐝
I've found this project fascinating and Ive learned a lot, thanks. I like the failsafe that shuts down the water flow, but if it was mine I'm sure birds, squirrels etc would land on the chain that pulls the pin out!
Maybe just cover it with a tube?
A bird sitting on the chain would not pull it out. and if it did the worst that would happen is a few hours of power would be lost.
@@KrisHarbour - thanks for the reply Kris. I hope you drop a few updates on the water wheel in from time to time, it's been fascinating and inspiring.
@@KrisHarbour
I don't think a couple of tits would worry it....
Great project Kris, well done.
Hi Kris, I have just moved to a 10.5 acre homestead in wales and I just started a channel. Thanks so much for the inspiration. I have watched your channel for years and it’s because of people like you that I am living my best life 👍
lol
Great stuff. I’d like to do the same myself one day 👍
Dont be disheartened, youve learned a lot, so have we, and thr job was successful regardless of the set backs. We live we learn. Every tradesmen goes through this as you know well
Good to see episode 5, I am enjoying these.
I find it odd that the generation of water wheel power requires the grid power to be up. It seems if the grid fails, the water wheel power would be most needed.
Welders worldwide always defend their crappy-looking welds as strong. But when tested to failure, they aren't really very strong. I'd fix it sooner than later.
I'm clapping 👏👏👏 after watching your Videos for the first time. Wow! The best green Channel on TH-cam.
Kudos for the Welsh production. Much more honest and relatable than most of the Hollywood rubbish, where no one makes mistakes. Well done Kris
Yes Kris, hope you see my comment. I was going to tell you in your last video when you mentioned that hydroelectric is better than solar panel, because first one is generating electricity 24 hours a day and solar panels only when its bright which is right, but the down side of hydro is it requires too much maintenance and solar requires very little to no maintenance
Very impressive how close you were able to come to the efficiency estimates in your brief. Beautifully engineered and executed!
Kris if you put a sheet metal ring attached to the wheel on the generator side. It will prevent water from splashing over onto your gear box, and generator. I know you have a cover, but it would offer some additional protection. Our forefathers would be proud of you. Great job.
Great to see the progress. In all of your video's for this water wheel, I only had concern for the thickness of that failed plate, with respect to fatigue failure. However, with 1.5 kW and 30 RPM being pushed through the shaft, I calculate that the plate at the location of failure was experiencing roughly 5 MPa of shear stress. The yeild of the material is roughly 200 MPa. The cyclic stress range would have had to have been 120ish MPa for the failure to occur within a few days. There would need to have been some crazy wobbling cyclic stuff going on that you weren't aware of for that to happen, and then the other side didn't fail. It had to be an issue with the material/welding.
Its awesome. Direct that energy to a heatpump and youre almost covered.
And ya jinxed it. Never make definitive statements about not going back 😂
Kris, i deal with a similar failure quite often on conveyor head rollers at my work, which are constructed in an identical manner. They never fail around the weld but always above like you've described. Ive been removing the head rollers and modifying them to accept a "ringfeder" or a keyless shaft taper lock. Obviously it would be a huge amount of work to carry out a modification on what youve got here, but may be a good solution for something in the future.
You may already be familiar, but these taper locks are very effective and reliable. Makes for ease of assembly and can transmit a huge amount of torque.
Excellent Wrap up Engineering. The current flow is ideal for full performance with practically no impingement. You've taken a unique old water power site and breathed new life into it with the modern controllers an monitoring abilities.
This goes down as one of the best technical design project progression video series ever made.
Many thanks to John the home owner that allowed you to film all of this! Your honesty, care and determination have been exemplary - his patience and hard work that he, and friends, also put in has been fantastic!
If you make more of these waterwheels ( I hope you do), I wonder if he is up for making the wooden leat???
The failure is most likely due to the steel having a heat affected zone (HAZ) in the area of the break possibly micro cracking and brittle fracture, your over plating should work but maybe an idea to read up on how to limit the affect (heat treatment for instance) Also relatively easy and cheap to check using dye penetrant technique. You may already know this of course 🙂Hope it all works out.
I wonder if there is a another design that doesn't require any welding?
I was thinking a few triangular flanges / buttresses from the shaft, spreading the torque forces out further onto the hub-drum.
Or not understanding or modelling the forces at play and just winging it.
It's the normal problem welding around a solid shaft, the weld shrinks as it cools and rips off the flange. The cure is first use flexible weld rods and secondly hammer peen the weld as it cools so the weld stretches, it's standard practice especially welding castings.
getting some equipment VT (white, red penetration & developer paint) & MT (magnetic powder & electromagnet, for cracks not visible from the outside) testing on high load areas might be worth getting. for increasing cooldown time and therefore reducing/eliminating martensite creation (hardening with loss of ductility other symptoms if the outer surface of the HAZ solidifies prior to the inside would be cracking due to the immense pressure buildup from the formation of martensite which entrains volumetric expansion), ceramic heating blankets might be a good investment too. and of course just proper preheating.
concerning the stick welds on site, i doubt that the rods were properly dried (there are mobile ovens for sitd welding so you always have some freshly dried rods on hand) so i would definetely watch out for hydrogen britleness, but if you go back with a mig and properly grind out all the old welds, should be able to save it.
Excellent build mate. Best one on you tube.
Hello Kris and Dot 👋 it's exciting getting a new video 😊
Firstly, I admire the research and work that you have put forth with your wind turbine and water generation projects. Much respect.
After retiring from mechanical engineering after 40+ years, much of it in designing for fatigue and mitigating fatigue failures of the designs of others, your construction of the water wheel rotor at the shaft interface was an "oh oh". I have seen many such constructions fail in fatigue much as your failure in a fairly short time. The thin "diaphragm" from the larger pipe to the shaft is very problematic in fatigue (lacking weld quality aside). BTW Multiple diaphragms only lengthens the process and makes the destruction worse.
When rewarding, clean surfaces very thoroughly, grind out defects as best as possible (worst enemy in fatigue), controlled build with MIG towards as large a radius as possible, cooling as slowly (insulate) between passes. Repeat process until access is gone, Finish with gringing, polishing, coating area with epoxy to protect. The torsional element of the stresses is not present on the non-drive end, but will most likely follow in time.
One of the best channels on TH-cam. I like how he doesn't use his videos to push merch or sponsors. Instead, he focuses on quality content and honest content. Other channels' content often feels contrived . I have followed this channel from the beginning and it is the one I have been subscribed to for the longest. There were other channels that I was subscribed to before this one but have unsubscribed because it seemed like their projects were created solely for the purpose of having another video to publish to TH-cam. Great channel and keep up the great work.
👍
Great job as always Kris. Defo a project to be proud of. All new tech have teething issues, so it takes nothing away from the engineering that's gone into this. Well done mate.
I loved this series on the water wheel but i cant hardly wait to see you working on the barn . Its been a long wait but i know it will be worth it. Without a doubt my favorite utube channel. Well done with the water wheel,i wish there was more contractors like you with your work ethics,honor and integrity.
as a welder,
- when repairing cracks like these, always grind them completely down and make a so called 'V' butweld instead of just running over them. It will most certainly crack again soon the way you repaired it now.
- always try to avoid vertical down stroke-welding.( specially on dynamic welds like this.) use an up going slightly pendeling weld technique instead, with for instance: E7018-1 Welding Electrodes . When using a MIG welder outside ( I personally try to avoid this ), make sure you have good gas-protection as MIG-welding is very sensitive for draught and polluted material like rust and paint. MIG welding proces is even worse when used in downstrokes. Only skilled welders get a good result using this technique, but even they will always try to avoid it.
- preheat all parts to roughly 150º C before welding. ( specially when welding outside or during winter temperatures! ) the material will most likely start to crack again due to sudden extreme temperature differences if not preheated.
- Take your time. welding takes as much time as it needs. rush jobs are usually double jobs.
- try to devide and spread the mechanical forces by adding 'knees' or 'traingles' on the axle towards the newly reinforcement.
but most important :
If you can't get your parameters right ? don't weld it! ( the right rods, machine, cleaning method), protected from wind, water and cold conditions.
It 'll cause more work in the end and in most cases potential damage/danger.
kris just because im an animal lover i have not seen the lovely cat , i hope nothings wrong. and love all your vids of course.
My father was trying to weld a bolt that broke off, one of the three connecting the exhaust manifold to his engine which he needed to replace. Space was extremely limited and his money for the truck was running out as he already had to purchase hard parts and rebuild kits for his transmission (one was the wrong model and buying from a shady site he was unable to get a refund, the second was from a more legitimate site and had good parts). He first tried drilling it out with some expensive bits, which first burnt out the drill then the two bits... he eventually, and rather accidentally, welded some vice grips to the bolt while the nut he filled and welded with all-thread fell to the ground. He did get it off, but it was a funny and not-so-clean job in a space he could barely fit two hands in. I think it's impressive you were able to weld in so tight a space, even with an arc welder that wasn't up to stuff. End result looks amazing :D
Great job
Don't be too hard on yourself.
Not many people building these on their own.
Kris, don't worry about how those welds LOOK. There are farming implements across the entire United States that were stick welded back in the '50's that look like you let your kindergartener loose with the welder that have held up to the test of time.
As you already stated, you must've gotten the steel way too hot around that weld for it to break. When it comes to welding that's really the only thing you have to worry about. To hell with it looking perfect for these TH-cam welders. I guarantee that when the cameras aren't looking they're boogering up everything.
Remember, welders are great at grinding and painting.
Kris, this has been extremely fascinating to watch. Thank you for taking us all in your journey!
There was a moment- perhaps only the breath of a hope - that Kris was leading us towards a simpler world, not least one in which we could rely on rain to fill streams to turn wheels that let us watch tv on a mobile phone. But it seems - even when it's simple and nifty - that when I look towards the skies, electronic dump load falls on my head. Still my favourite content anywhere in the universe. ❤
Really enjoy your channel and its content. Stuart from Melbourne AU
That relay and safety mechanism is simple, effective and genius. Absolute pleasure watching this channel. Brilliant!
You had some days off work over Christmas, how dare you hahaha. I hope that you took at least a week off, if not two, glad to see you are looking relaxed and ready for another year. Happy new year.
We all get days like you had, and you can not carry everything around with you. Been good to watch and I hope you all celebrate well and raise their glasses to you and your customer. For undertaking this project, well done and keep safe!
Very interesting series and impressive job!
Loved it at 1.38mins 'conclude this project' - I bet you honestly can't wait as its been a bain for you I imagine 😢
13:05 master transition sir... unintentional or not.
Now your overspeed switch is beyond brilliant. Well done.
Congratulations Kris, your first professional water propelled electric generator, installed and running. I love it!👍👍👍👍👍👍👍👍👍👍
Loved watching this series! My only addition would be to avoid using galvanised steel bolts in with the steel bearing housing. You can see the zinc in the galvanised steel is already causing corrosion in the carbon steel, due to the difference in galvanic their series. I would suggest using a sacrificial anode or using nylon washers to separate the metals.
It’s great seeing the whole process. And not just the celebrations or not just the failures, but the reality of what it takes to be successful.
Honesty the best practice well done.
More videos please 😂. Love this channel!
Really enjoyed seeing this Kris, perhaps an update of one years worth of generation wouldn't go amiss.
Regarding the cover/enclosure for the gearbox and generator - from what I could see, it appears that the housing is open from the underside, making it possible for a curious child/cat/squirrel etc. to access the rotating pulleys and belts. With older cars or tractors such accidents happened occasionally when cats got in there attracted by the warmth of the engine. I'd recommend putting some perforated sheet metal or wire mesh there, so ventilation is still possible but the moving parts are shielded.
It certainly doesn’t comply with the Supply of Machinery (safety) Regulations and therefore doesn’t have a CE or UKCA mark. I’ve raised this before and it wasn’t responded to.
It might seem a bit mean to raise this but it’s enforced by the HSE and is criminal under English Law. Just being a one off designer and erector doesn’t mean it doesn’t apply.
Great work but follow the law.
@@paulharrison2325 I design and manufacture custom embedded systems that go in various hvac and industrial products. I noticed that as far as regulations for conformity/safety etc. go, such stuff is often handled a bit lax, except for the large companies that have copies of all relevant standards (expensive) or contract this aspect out (very expensive). The smaller companies or startups often don't even know there are regulations regarding a particular issue and that they might expose themselves to lawsuits or liabilities. Do you know any other solution for a small startup or 1-man operation except making a best effort to gather information about the relevant standards, purchasing books about the topic, and maybe purchasing the relevant standards as originals and then of course go through your design and make it conform? This topic is easy if you are an employee of a big company (go to the library) but if you just started and you need to buy so 2000€ worth of DIN or IEC standards just to actually know what it is you have to comply with, that's a bit harder. IMHO this information should be public, such that even a 1-man operation has all the info available to check if they are doing everything as it should be. Like it is with building codes for example.
@@tpa6120a2dwp the Supply of Machinery (safety) Regulations is freely available. It’s a law agreed to by parliament. I deal with small and large businesses in the engineering sector and they all understand what a CE mark/UKCA mark is. You don’t have to follow British Standards etc to comply with the law, it’s just one approach.
I suspect in this case, what he is building needs to comply with the Supply of Machinery (safety) Regulations (what most people call the machinery directive) and the Low Voltage Electrical Equipment (safety) Regulations. I can’t see any items that separately require compliance with the Construction Product Regulations.
For both, this type of work would be self-certified (a declaration of conformity) but you have to follow the process. Unfortunately I don’t think the water wheel complies with the machinery directive just to the number of unguarded moving parts. I can’t comment on the electrical side as what he has shown is limited. Note that just because an electrician has carried out the 230 V work doesn’t mean it complies - there is a control system and dump system etc which all needs to comply.
Unfortunately accessing standards is expensive. I use IHS but this would not be affordable for a one man company. Lots of engineering memberships give you access to similar electronic libraries however.
I probably need to reinforce the point - in the most part, compliance with regulations does not absolutely require you to follow standards. However, in some cases it does or for all intents and purposes it does. Try to sell a structural steelwork product not compliant with EN 1090 for example. Thinking it through, I can’t tgk k of any specific standards he would have to work to except BS 7671.
The problem with not following CE marking is that it is criminal, not civil.
I love your customers disposition. You learn and all of us. Give that man a Bells.😊
Yep, the customer has been great and part of the fun of getting it working.
Congratulations! Job well done 🎉
Top job enjoyed the series cheers
This project was a good illustration of all the advantages of a turbine setup. Smaller, easier structure. Easier to adjust and turn off flow. More efficient power generation. The only advantage the water wheel has is no high pitch whine. I guess if it's just a fun little project that you don't really need for power then the noise is the most important factor.
Where do you buy your turbines? I need one to catch the 20kW power going to the Atlantic every minute.
Congratulations on achieving a successful outcome on the water wheel - fascinating engineering. Happy New Year, Kris.
Great job Kris you know what they say on welding jobs " the bigger the blob the better the job " lol 👍👍
Congratz to a job completed.
Great video Sir, It could probably do with a bit of heat treatment, stress relieving with oxy acetylene, heat it to orange and let it cool down in air
Great video series, thanks. A very interesting project showing all the problems that have to solved when designing any system, there's always RV 1, 2 etc. In the old days the miller would be the control system, using eyes, ears & years of experience to control the flow. When building windmills & water mills they must have faced the same issues.
I have been a welder for almost 40 years, so I FEEL your pain brother . Welder kicking out the breaker constantly because your trying to run 110 volts .. done it. No 6010's or 7018's around just " Jet rods" to do a job . . . yuck! ... Using a helmet with an auto shade drives me nuts .. I'm old school, I can drop my shield by just thinking about at this stage of my career...haha.
I'm spoiled now...I decided to take a job in a HUGE shipyard here in Canada...no more climbing over pipe racks to TIG weld stainless in position with 100 percent x-ray's on the whole line.
Everything I do now is simply pressure tested, so one little speck of tungsten is not a cutout like it used to be.
Hi Kris. Stumbled upon part one of your water wheel videos a couple of days ago, and I’ve been progressing through to this latest one. I’ve enjoyed them all. They’ve been educational, instructive, and thought provoking.
We have 4 kW of solar and today, the 29th of January, 2 kWh. As you say, it’s the constant output, 24 hours a day, that makes water generation a practical solution. Mind you, the owner is very lucky to have a river flowing past the side of his house.
Now subscribed, so looking forward to seeing another report in around a year’s time, as others have requested.
Many thanks Noel.
Loved that project amazing 😊
Very impressive project. Great to see natural power being harnessed in such a clever way using old and new technology in harmony. Well done.
So glad you took a break over the holiday, you look rested so it definitely worked. I do enjoy your videos Chris, as an outdoorsy type myself but with chronic fatigue (long covid) for the last 18 months, I don’t get out much anymore and the beautiful countryside around you is a tonic for me, makes me want to get better.
Thanks
You’re true and honest with your work which shows through in pride. Looking forward to some more barn work. Excellent. Thank you!
Amazing bit of work! 👍
Teething problems on a large, one off job , like this are inevitable . It's the manner in which it's dealt with, shows your skill and integrity . This, you have shown in all your projects. Well done fella. Looking forward to the next vid.👌👌👍👍.
This is really impressive and inspiring. I’m surprised that you’re able to get so much power out of a wheel and have it look so good at the same time.
Good job on your water wheel… that is making an electricity for that customer free!!
Beside the barn I miss the garden and the geese. Congratulations on finishing water wheel project!
Loved the series
Really enjoy these videos and your honesty about your work. Especially the type of pride in your work that you show.
Keep it up!
Hi Kris, your cracking was very likely caused by fatigue. Depending on the source, its reported that around 80-90% of metallic failures on moving machinery are due to fatigue. Fatigue happens when you have a cyclic stress regime. In something like this it could be caused by a misalignment of the shaft/bearings, but I think you were quite careful on that front. Another possibility is that there is some kind of load being fed back up the shaft on that side from the alternator, possibly when it is trying to control the wheel speed. Hopefully your fix of generally beefing it all up will help to reduce the stress. The bigger weld looked to have a nice radius on it. If the worst happens and it does reoccur, you might want to think about how to reduce any stress further, such as changes to the breaking load fed back up the shaft, or by further spreading the load on that shaft/flange intersection.
slap a 20mm leg TIg fillet on it and itll be fine 🤣
Great work and series, thanks for showing the problems along with the successes, very honest and brave. Looking forward to more like this!
Been a great series, well done!
Congratulations Kris; job well done ;happy new year to you 👍👍🇨🇦
Great project, you did a wonderful job and the customer should be quite happy to have worry free clean energy for many many years to come!
Lovely videos ans so cool what you r doing..
Can you maybe teach us the electricsl work, and generating currents, and watts and Volts and Amperes etc.?
What we would really love is if you could make tutorial videos for laymans to learn the electrics...
From somebody like you, who has so much practical experience now at your own homestead
0:55 "..it's a proximity sensor which reads the speed of the wheel which goes to a tachometer relay and then that relay monitors the speed. If the speed goes past the set value it then opens a relay then sends power to an actuator which then pulls an arm which pulls a pin out which drops the flap..... It's very simple"
Just want to remind you Kris, this is not very simple for 'simpletons' like me. Just saying - it may seem obvious to you, but to me it's incredible.
You do a great job of explaining how everything works. The more I watch your channel the more "simple" these engineering feats seem to be. I want you to know you've given me the knowledge and confidence to build a post and beam woodshed (4mx6m). I wouldn't have been able to do that if I hadn't subscribed to you years ago.
Thank you for sharing your knowledge
Glad to see you back. Looking forward to the barn, garden, and rural life in general.
You know what Kris, you've got a real talent for engineering. There's always mistakes along the way but you've got such a great ability to see where fault is in the system. It's impressive.
Love what you have done!. A couple of things to improve water flow, first use something like a 6mm rubber mat over the uneven water flow at the corner of the wooden water lead to the top of the water wheel . This method of even out the waterflow, is used in most commonly on large gold sluices. Also use a corrugating roof shape to stop very sharp drop and big splash back and loss of water entering the top of the turbine . A corrugating shape will spread the water load .
Love the wheel. One thing you might do to reduce splashing during high flow periods is add a 1m long rubber mat draped off the end of the wood sides of the chute that is just wide enough to be in between the sides of the wheel. It would help contain the splash and keep more water in the buckets. Excellent job.
Thanks for posting and sharing. Great to hear that you’re feeling good enough to move on from the water wheel. Great to see the final result.
Great job! It was an amazing project!
Love the amount of redundancy built in the system. Well done!
This was really interesting to watch, and seeing you problem solving and fixing it was great. Looking forward to seeing you finish the barn.
I really enjoyed this series! I loved all your different fides for the problems you encountered. Great job and great video. Thanks again 👍
This series was my introduction to your channel, I can really emphatize with the frustration and stress you must have gone through. Like others have pointed out, it's always better when the the low points get included as a professional instead of just rose-tinting everything. Cheers and looking forward to future videos!
Hay Kris, we got a good laugh watching you explain the complex process if this then that. You might not remember the old Mousetrap game, for children. You made me look up an TH-cam video, for that game, we enjoyed looking back so funny. How smart that was, I guess computers are here because of all the kids that watched those commercials and played that game. Probably 60+ years ago.
You learned a lot from this project.
Even if you have fifteen KWH per day that is a really useful amount of energy to be getting from a piece of instructive art 👍🤓
I would have used a linear actuator which raises and lowers the flow flap. This way you can reset it automatically rather than having to have a human reset the system. You would still use the 24v supply, but it would charge a battery which would deal with power outage. I am an automation specialist so if I can assist you with your methodology please drop me an mail. Absolutely love what you do.
Fantastic work
Loved the series Kris, what a brilliant project.
I have been following your channel for a long time. I am always amazed at how well you manage to make this topic understandable to me, an absolute layperson in electrical engineering. Thank you very much for the great entertainment!
I am glad you are back Kris. I've been wondering about the water wheel and the barn project. Hopefully, you all had a great holiday season, and I'm looking forward to finishing up the barn, which I know is about 30 videos from completion.
