- Developed from the popular myfordboy EZ Stirling, this engine is even easier to build and will run on a cup of hot water. For your free plan go to myfordboy.blogspot.com
Can't get the travel sweet tin? Alternative constuction methods are given. - แนวปฏิบัติและการใช้ชีวิต
I rarely sit through 30+ mins of anything on youtube (unless there is an injury involved), but this was brilliant. Good job.
Thanks for this wonderful and precisely detailed video! One small tip: The difficult process of coaxing the plastic bottle piece around the two tight-fitting lids should become very easy if you just freeze the lids first. They will only shrink a tiny bit during the freeze, but it should be plenty, and as they warm back up, they'll snug into place.
Stirling engines are a great hobby! I love tinkering with them.
This is by far the best instructional video I've ever seen for building a Stirling engine. Great work!
I usually prefer to get only the concept in a short video BUT in your case I learnt more of engineering tricks that made every minute of the video worth watching.. شكرا :)
10:03 You are the lord of the rings
This is still my favorite Stirling engine video. I remember watching it the first time before I started collage. Never could find tins and a soda bottle to fit together.
Excellent ! Thanks especially for listing the required parts right up front. It’s annoying to have to put everything on hold because yet another part or tool has to be found. All the best to you.
Brilliant video, I especially love the soldering iron trick.
That's a pretty cool way of making a tiny drill!
Easy, simple, brilliant and excellent..!
It is the best I've seen..!
Thank you so much.
Great plans and video. Here is my result: My First Stirling Engine (LTD)
Thanks myfordboy, I finally finished mine. I modified your design a bit to suit my resources. I was able to get it to run for over three hours off of the same cup of water and multiple ice packs! I was able to get the most out of it by frequently switching out my ice packs to new ones.
datonekid Well done, your engine runs well.
Check them out my channel if you have the time!
Excellent video! Everything is clearly explained.
this sterling would make a great custom made teapot cap and will indicate that the tea is still hot:) Thanks for showing this simple yet very amusing build.
Thank Myfordboy for this nice video.
I have just built this awesome device and it works like a charm. I followed the indications from the video and measures in the plan as close as I could. It took me three days (most of the time awaiting for the glue to set). Some tips that could help others to success (many have already been commented here):
1) Do not use a balloon for the diaphragm (as I firstly did) since it is too stiff. A latex glove is the best choice.
2) I have found that, at local markets, the circumfererence of different 2 litre PET water/soda bottles varies from 30 to 33 cm. The travel sweet tins have around 31 cm so finding a bottle that fits properly was not that easy. If difference doesn't exceed a few millimiters, electrical tape can be added around the tins to get a perfect sealing.
3) Everything should run very very freely. Make sure there is no friction in the wheel and/or in the displacer needles.
4) PET deforms with high temperatures so I would not use heat sources hotter than boiling water on a cup (forget tea candles, lightbulbs, etc).
5) The adhesive of bottle label can be easily removed with oil of turpentine. It doesn't affect PET transparency at all.
Good luck
You are first people, who showing how I'm going to do it.
I'm one of them, your videos are awesome just the way they are. People can skip through the video and listen to music in the background if that's what they want. Keep up the amazing work, it's rare to find a channel like this.
The most handsome sterling engine - from materials to color - !!! Science and Art blend.
I'm trying to make a sterling engine and this is the best video yet
I have several engines with that configuration, all run well.
Excellent video and tutorial!!!! These engines are easy to build and a great way of adding additional teaching to my class! Well done!

Congratulations on the concept, the engineering design and the construction, I like the fact that the power piston is very close to the displacement and so effectively the compression ration is a maximum relatively speaking which means one gets the maximum efficiency with a higher compression ration.( relative in this case) The idea of the phase displacement between the power piston and the displacement of 90 degrees is well projected and the fact that the engine reverses due to changing the heat sink to a cold sink is excellent as it can be followed visually, It is a great model to teach heat engines to students too, even at University Levlels, Congratulations once again as the workmanship is good enough for any one with a good attitude to make it, People these days do not know how to occupy their free time and all they want is to be entertained by others, This is a situation where people can learn about themselves, about their deeper thoughts and about their own clumsiness factor to get things synchronnised and accurate, Well done sir,
After two years I came back to this video and cannot help admire the little ingenuity behind this design. The fact that the displacement piston is placed in a transparent container one can clearly see the two actions that give it a double acting cycle, one when the air is on the hot side due to expansion and the other when the air goes to the cold side due to contraction. An elegant and such a beautiful design. One would indeed be wrong to say that this is a simple design, for it is not simple at all, it has got its dignity to keep up and in fact it is a rather complex cycle. I believe one hot air engine was introduced in a Swedish submarine and this pitted its wits against the American might and due to the silence of the Hot air engine propelling the submarine, it went through the American defence lines without being detected, all due to the fact that the Stirling Engine does not use "explosions" but an expansion is great silence. Again , congratulations.
@@carmelpule6954 why write an essay when you could have just said those points in few sentences. Man you must have a lot of free time lmao
Congratulations on this detailed video.
I also really like these engines.
Greetings from Brazil,
Leandro Wagner.
that's a great trick with the soldering iron to cut polystyrene foam
Tin lids, water bottle, and similar scrap bits. So much for all the stuff about how hard it is to get an LTD Stirling to run.
Greetings!! its really too precise work, i laughed lot during jokes you passed in between, appreciate your sense of humor, I will try this for my kids project now. Keep it up
a little tip for removing the adhesive from the labels on bottles and stuff, works with price tags that are stuck on really good too, spray a bit of fly spray on it, leave it for a couple minutes, then wipe it off with a cloth or paper towel, it comes right off
Great project, I hope you have some school teachers as subs. This would be a great school project. Nice job.
looks great! i've built your other design a while ago and it ran like hell! maybe it's time for the next
I personally find the videos too short, I hate it when they are over. Have watched them all many times and it never seems to be enough. Same for the lack of music, if I wanted music videos I'd turn on MTV.......... Keep up the good work!
Good question!
this is great! helped me a lot in my physics project thank you
Very Cool! Can't wait for the plans
Very well done, loved the little tricks also.
However! I mean, come off it buddy
Even Liberace called them Popsicle sticks.
Hi
I love His background with corrugated cartboard
Nice video cant wait to try it one small tip use latex gloves so your fingers wont get souled .
Great craftsmanship.
It looks easy after you figured it out for us :)
well this things charming as hell. gonna need to make me one of these
thank you for video it's so simple for my project for school
Just great job man, hold so on.
I made the coke can version but you need a lot of heat so I'm looking forward to making this one
Stick to your formula, myfordboy; I love your videos!!!!
Very good with sunlight, lenses and mirrors could make a move for one dynamo and feed electric appliances.
Muy buen video , Didáctico, tiempo real ,y muy instructivo,.Realmente lo felicito ,he visto todos sus motores y se diferencian de otros que hacemos este hermoso hobby es la sencillez y la efectividad de todos ellos .......LO FELICITO
Are you joking, I'll bet NASA will find this a challenge. At minute 28:44 you mentioned it will take a bit of patience to coax it into place, OK that rules me out. I just had to watch this to completion, to see it work. Great video as are all your videos and projects. Thanks for sharing...Ken the old guy in USA.
Very doctor Suess ,I love it thanks for the share
Cool: such clear instructions and such a nice simple design.
Very Cool, My kind "constructed from stuff found around the house" build.
Bravo,Veramente,Paziente e Preciso.Complimenti.
Just made one of these with lots of time put into it. I must have gone wrong somewhere but i gave it a shot. Did not work for me. I think my flywheel assembly might be the problem. Great upload though and good instructions.
Thanks sir, I looked a video to help my project.
this is great. awesome details
Very nice Thanks for sharing.
Very interesting project. Love your videos, just as they are. Music or talking would mess them up.
Just built one successfully. it's quite hard to find tin lids that fit plastic bottle (USA, California). what I did was to use 2 tin lids and cut a 2 littre Coke bottle ring. Then I cut the ring down to fit the lids and glued the joint (with the same Coke plastic piece over the joint). Secure with a little epoxy. Thank you, my run time is 14 mins over a cup of near boiled water, can be longer if I pay more attention to bearing, leveling... My co-workers asked for one... (:
Great solution.
A small scale one like this (or maybe a bit bigger) would be great if you had to trickle charge something in the middle of nowhere ❤
I save all my JIF jars, cleaning the labels off of them, I use a silicone spray for the major portion of the glue and rubbing alcohol for the final cleaning. Seems to work for me.
love this for my son school project , specially the HAVE A DRINK part....
That is slicker than eel snot. I'm thoroughly impressed with every aspect of it. Even how deft you are at making the parts and fitting them together. I wonder if I could maybe make one of these. I'll have to look at the plans, the crank assembly was a little small for me to see what you did. It's not you, I don't see so good. I'd love to have one of these because the principle and the fact that you can get usable work from it is just amazing. I'll have to modify the materials from UK to available American style goods. It would be a great conversation piece!
+Robert Smith Send me an email for a free plan.
Impressive Sir...Cheers
Excelente, de los mejores que he visto.
very practical the way you did
Well done!
The perpetual motion engine.
That requires an energy source to actually work.
I think they already invented that.
But it does look like a fun project
i believe thats why he called it a "stirling engine" in the title. I will be making one, learn alot from it
The speed you eat the sweets in no way effects how the engine performs!
good joke :)
it was just a suggestion.. and you can use relaxing music.. 37000 subsribers.. :) just joking.. i will replicate your project! thanks!! great job continue like these!
Rulof Fai da Te hi I watch your other Channel
🔴 What Is Islam? ⚠️
🔴 Islam is not just another religion.
🔵 It is the same message preached by Moses, Jesus and Abraham.
🔴 Islam literally means ‘submission to God’ and it teaches us to have a direct relationship with God.
🔵 It reminds us that since God created us, no one should be worshipped except God alone.
🔴 It also teaches that God is nothing like a human being or like anything that we can imagine.
🌍 The concept of God is summarized in the Quran as:
📖 { “Say, He is God, the One. God, the Absolute. He does not give birth, nor was He born, and there is nothing like Him.”} (Quran 112:1-4)[4] 📚
🔴 Becoming a Muslim is not turning your back to Jesus.
🔵 Rather it’s going back to the original teachings of Jesus and obeying him.
You don't want a night light under this one, it will melt the plastic diplacer cylinder. Have a look at my EZ Sirling if you want a higher speed. Black paint only useful if you are looking for solar power.
Will you ever make a version of this for lathe users? It would be a nice entry to Stirling engines.
This engine is a simplified version of this one th-cam.com/video/hazK8kxd-uA/w-d-xo.html This engine needs a lathe and was not designed as an LTD but could easily be made into one. I can send plans if you send me an email address.
For the assembly, if you put the tin in the freezer for a few minutes and the water bottle section in the nuclear oven for 3 to 5 seconds it slips together very easily the once all is the same temp it is a very tight fit without the chance of disturbing the rest of your assembly. Have fun
Did you just call a microwave a "nuclear oven"? A microwave oven is no more "nuclear" than a radio, mobile phone (cellphone), or a torch (flashlight)! Also, microwaving plastics is an incredibly bad idea as they can melt and distort. Hot water would be a thousand times smarter.
I love this design. There are no many tutorials for LTD. I built one but I have not exact material. I cannot find a bottle with the same size as a can. I used tuna can top and 1 liter plastic bottle. I joined them by epoxy. You can see it on my channel.
+Powered by Sergey You can water bottle cut and paste with glue, anti-heat
+toube TV thanks
Powered by Sergey You are welcome I am in the service (Arabic and proud)
brasso will take label glue off real easy!! Old One Legged Joseph T
What about spray-painting the bottom lid matt black for better heat conductivity, say if you used a light or a tea-light candle?
cool spezial effectss :D
i like landscapemovies *-*
thanks for this post
How about building an opposed piston engine?
ECOmotors has one, supposed to be 50% efficient, 50% lighter.
Very cool project!!
What do you think?
greetings from brazil too
how do you make it more air tight?
Great video.
Hi myfordboy , this LTD stirling engine , can it work on higher temperature differences ? or will it only work with low temperature differences ? example if i were to use an alcohol burner . thanks in advance !
+Yi Ming This design is optimised to run on very little heat. If you increase the heat the plastic cylinder and foam displacer will melt. If you want an engine to run on a spirit burner or candle try my EZ Stirling or Pringle engine.
thank you very much!!!
What is min temp difference and how much temperature should be there while heating
All the materials can be got at Lidl.
Eso sí que está muy bueno felicitaciones y saludos.
As I watch this I can't help but be reminded about "Hands".
innovatively inspiring
It may not the improbability drive, but still uses a fresh cup of tea.
eureka!!eureka!!!!!!!it's working!!!!!!
VEry nice engine
Awesome video but where in the world do you get those candy tins? I can't find them anywhere!
how do you calculate the efficiency from this engine?
I like the design, now if I were only rich enough to waste my money on such common items so I could make it... [however I live in the US and never even heard of travel sweets, they sound yummy
Hi Myfordboy, How did you fit the diaphragm crank onto the crankshaft firmly? I noticed it was glued onto the flywheel for the displacer crank, but im unsure about the diaphragm crank. Please help. Thank You!
Its clearly shown on my free plans, just ask for a copy.
28:00 Maybe use distilled water as a lubricant? Or, chill tin in the freezer?
Where can I purchase those indefinite lasting light bulbs? ;)
This sould be usefull in a place where you have natural hot water right? Like a hot spring?
Or ice.
I need your email so I can send the plan to you.
ottimo lavoro
Pls myfordboy i love yours projects but do you know anything that can replace the two tins of travel sweets? Thankyou
Rodrigo Drumond You could try the Pringle engine th-cam.com/video/Ow_mBbd2jWU/w-d-xo.html
Not LTD but designed for builders that cannot get suitable tins.
nice project
Bravo 👍
