This guy is a legend! I vividly remember his shows in the early 90's. Back then I was a 10/11 year old Dutch kid with only a limited understanding of the English language and there were no subtitles. Nevertheless, Tim and Rex managed explain the basics of how things work. I don't know why, but somehow I can hear "this is recorded on sticky tape and rust" as if I'm watching that episode right now. 😄
I really love playing with everything mechanical and electrical . I watched your videos 4 times. At least. I now the way must of those systems works But it’s still a pleasure to look at you explaining the Hole thing again. I made a long trip to visit the watch museum and the automated musical instruments, also amazing. I went to this museum and it was closed. For maintenance. But after they learned that my trip was more than 8 hours of plane plus few more by train to reach Suizerland they reopened the museum just for me for free. I was the happiest men on earth.
Tim mentioned vacuum bellows used in cars - my Land Rover used to have its cruise control throttle mechanism controlled that way. One might remember the old distributor vacuum advance too. The vacuum tube system for moving items around is used in the nuclear industry for moving radioactive canisters around quickly and without human contact (I forget but there is a university department in America that has a system that runs over a huge distance between labs). Perhaps Tim mentioned it but pneumatic systems work well in 'explosive' environments where the risk from an electrical spark would be a real problem! What a brilliant video - we are so lucky he is still broadcasting albeit on TH-cam!
I have no want to meet ANY "celebrity". A bit of a disdain for most of them actually. I'd PAY to spend a couple hours touring Tim's shop and absorbing everything he had to impart. His videos are some of the absolutely best content available. And he imparts his knowledge for free! Thank you SO much and PLEASE continue, as is comfortable and enjoyable, to keep educating so many of us who absorb every video like a sponge. Oh how I wish I had such instruction as a child.
Great to see Tim back doing at what he does best, entertaining through technology. I am still loving the Secret Life series as much I did when I was a kid. Absolutely brilliant.
As a maker, mad scientist, amateur scientist, professional engineer, and so on and so forth, I can hardly express how much your shows, both old and new, have enritched my life. Thank you!❤
I've always wanted to do something with pneumatics - the action is so satisfying! You can get oil free compressors pretty cheaply nowadays - I think they use two or more diaphragms to avoid any friction surfaces that need lubricating
I have several oilless piston type compressors, all salvaged from wrecked cars with air suspension. One has been my tire inflator for the past 20 years, been run until it was smoking hot numerous times, generally abused, and still works like new. Most of them have an integrated solenoid bleed valve that's handy too.
Or compressors from used fridges and A/C units - They can be used either as a compressor or as a vacuum pump. However they won't last long without proper lubrication applied directly into the intake air...
Great to see you back, I remember your TV series when we were all younger, and have loved your practical approach to passing on your knowledge and experiences ever since. Thank you...
Wow, I had no idea you had more shows out! I have entire series of The Secret Life of Machines saved! As soon as i finished watching, I donated! I'm a Machine Operator at a factory and Pneumatics are used *extensively* both on the machine I run and elsewhere in the facility. They even have air-powered pumps called 'Sandpipers'.
You remind me so much of my grandfather. He was so smart and always in his shop devising clever devices of all sorts. He built a elevator in his house in later years and used paddle wheel pump and cold creek water to cool his house back in the 40's.
8:35 Oh my I remember playing that one in London last year during September! I still have the 'nuclear waste' as a memento to the wonderful time I had. Thank you for your service Tim. Greetings from Germany!
As a child, I loved Tim and Rex in The Secret Life of Machines. As an adult, I'm in disbelief the YT algorithm did me such a solid as to show me this great man is still at it 35 years later!
A genius. Lucky enough for us that he lives in Suffolk. Rex Garrod and Tim reflected true English inventiveness with that edge of strangeness! Rest in peace Rex, but long live (Sir) Tim!
I turned thirty last year. I really struggle to know who I am or what I want to do with my life. The one thing I've always been fascinated by, but for most of my life struggled with, was creation. Telling stories, making THINGS, anything at all, even pointless things. But so much that I've considered doing has been too complicated to even approach. Too scary to even research. The Secret Life Of vids are so satisfyingly done, spectacularly well explained to help demystify what might as well be magic if you don't look under the hood. Just want to say thank you for these. Really helps to show that taking the first steps into things like this isn't so hard at all.
I've been in engineering for 21 years, I should have been shown this as a training video as an apprentice! You've taught me things about components that we use but never really understood 😊
Tim, what a joy to watch this episode! I really like your clock in the London Zoo and can imagine the troubles you had to keep it running. 15 years outside is a challenge on it's own. I designed and build a lot too and experienced that time will wear stuff out eventually especially in harsh conditions like production lines or outside. I would try a Hydrovane compressor. They're not that expensive and are very durable. I own one for 20 years now and it never let me down. I buy a maintenance kit every year or so with a new air filter and new oil. Maybe a tip. Thank you for sharing all your knowledge and wonderful projects with us. All the best, Job
I hope to one day visit this arcade. These videos are so much more helpful than many others on YT. I love how it just comes down to his decades of practical experience (and it's broken up according to how he approaches making these machines).
Age counts big time. Unfortunately, most of the youtube makers are young (that in itself isn't a bad thing), but wisdom and experience is considerable more dense in older engineers!
Tim!! SO glad to see you again. I've shared a lovely many hours viewing your videos, new and old, with my aging father, as something to do with him that he laughs so heartily with. Thank you. You've reminded us both of my childhood with him, watching both weird British TV stuff (we're American) and these wonderful educational videos by very clever people in those times. It actually reminds me a lot of many other TH-cam creators I've discovered lately, including yourself. Thank you very much. We love you and appreciate all your work, back then and now. You deserve all success possible.
Thanks Tim for yet another brilliant insight in everyday items. Always entertaining and informative. Lovely to see the dedication to Rex & Graham. Watched your TV programmes when you were on C4. Under the pier show & Southwold are well worth a visit, you'll not be disappointed.
I wish I could give you two thumbs up. I really enjoyed the secret life of machines years ago. It was my favorite TV show. Thank you for creating this series of videos to pass on your knowledge to those younger mechanically inclined folks today!
A million things to watch on TH-cam and I have already watched this particular episode at least6-8 times, not to mention how many times I have watched all Mr. Hunkins videos. I wish Rex was still here to be involved.
Very good! I had a Ford that had pneumatic windscreen wipers, powered from the intake manifold vacuum. They stopped when going up-hill, due to a lowered vacuum!
I remember those - you had to slip the clutch and briefly rev the engine to get a quick wipe going uphill in the rain. VW had a system which worked off the air in the spare tyre. If you had to fit the spare then you had no wipers so I guess that Ford's method was less bad than the VW.
Ah, a new Tom Hunkin Video! The Magic of Your Shows are Still There! You are the Common-Man's Treasure! I have been watching and following you since I was a young man, and we are kindred spirits in Tinkering! Even though I have been in industry and around pneumatics, I learned a few new things (as usual!). So thank You! When you pass, and go to heaven, may you have a fully outfitted-shop attached to a McMaster Carr warehouse!
as a professional mechatronics engineer I find this series of videos incredibly educational and what's more explained in very simple terms and practical. Thanks a lot for sharing your vast knowledge!! very cool arcade machines too!
I watched Secret Life series years ago and missed it when it went off the air. This week I stumbled across Tim’s TH-cam channel and I have been on a binge ever since. Nice to see Tim still going strong. Can’t wait for future content!!!
Fantastic stuff all round Tim, I remember watching you years ago on 'The secret life of... ' Your creations are brilliant! Thanks for all your videos and explanations.
Tim glad you are back. Absolutely made my day. Having a very hard time through bereavement and just rubbish work but this made me feel so full of happiness. I work in oil and gas, it’s all about control.Glad to see you doing what is brilliant… Love A xxx
Thanks Tim. I'd not really thought about pneumatics for a long time. I had some pneumatic lego when I was a kid but that's really the only time I've played with it. Maybe I'll start using it in some projects now your video has refreshed my memory of it.
I had the early Lego Technic or Tech Set as it was then so I missed out on the pneumatic Lego Technic. Do they still include it in any sets or is everything screw jack driven?
You are a national treasure. Wonderful insights into your creative process. Love your enthusiasm for all things material and artistic at the same time!
Legendary to see a new series! Also that pneumatic residential elevator near the end, wow!! Thanks for continuing to inspire, and sharing your knowledge and creative personality.
My grandfather used to build ride-on steam Railway engines, he was a member of the North London Society of Model Engineers. I now find myself gravitating towards more and more mechanical engineering. I think you two would have gone well, both working out of a problem using experimentation. Glad to see you back. Ast...
Tim. I think you’re somewhat unique on TH-cam in providing not just a high-level how to but also a semi complete survey of the equipment involved. It is awesome! I was voided using pneumatics for years and having watched this I feel confident to be able to launch into my own projects. Thank you.
in all sincerity tim... thank you for your works sir. it's been a pleasure to have followed your builds through the years. thank you for the continuity. such things are priceless sometimes. =dok=
If you want to check out low pressure pneumatics, look at the W123 in your drive! The central locking is all vacuum powered. You'll find a huge vacuum tank at the top of the boot, and lines going to all the door and the fuel filler. A valve in the driver's door is connected to the lock plunger, and switches between 2 vacuum motors like the VW one you showed. There are other similar ones in the dashboard for the HVAC to move the blend doors. On an old diesel Mercedes there's a valve connected to the accelerator linkage which simulates a gas engine manifold vacuum, for the automatic transmission. I've taken mine apart, but still don't understand how it works. It must operate on a similar principal to the pressure regulator, but I don't see how it doesn't create a vacuum leak. My 1991 Benz adds to this a vacuum amplifier device which modifies the accelerator vacuum valve with boost pressure. The ignition switch is pneumatic too!
An absolute masterclass. Loved every minute. Interesting I noticed because Tim is left handed I could imagine myself (right handed) handling the pneumatic tubes etc as he demonstrated their workings. I think I might wear my red boilersuit next time I watch. If only I really could be the wonderfully imaginative, artistic, amusing, engineering talented Mr Hunkin!
I so Love this guy. Can't believe he is still working hard for us. Thank you so much.
Agree, it's fantastic!
This guy is a legend! I vividly remember his shows in the early 90's. Back then I was a 10/11 year old Dutch kid with only a limited understanding of the English language and there were no subtitles. Nevertheless, Tim and Rex managed explain the basics of how things work.

Totally agree, this is invaluable
Me too, only I was older. So much information
I really love playing with everything mechanical and electrical . I watched your videos 4 times. At least.
I now the way must of those systems works
But it’s still a pleasure to look at you explaining the
Hole thing again. I made a long trip to visit the watch museum and the automated musical instruments, also amazing. I went to this museum and it was closed. For maintenance. But after they learned that my trip was more than 8 hours of plane plus few more by train to reach Suizerland they reopened the museum just for me for free. I was the happiest men on earth.
Welcome back Tim, absolutely overjoyed to see a new series and guaranteed there won’t be a better series of videos on YT in 2023. 😊
I can guarantee there will be nothing better than this on Television !
Looking younger than ever and just as entertaining. You and Rex got me into engineering. Hard to describe how grateful I am.
Same. I owe a lot to Tim and Rex.
I have always enjoyed Tim Hunkin's work. I have been a fan ever since watching the Secret Life of Machines series in the 1980's. Thanks Tim.
May not be an expert in pneumatics, but a hero in our minds. The world NEEDS Tim.
It's decided....your arcade is on my bucket list. People like you are the reason I want to make videos for edu-tainment purposes.
I'm an engineer and you are an absolute inspiration. I've also been to your attraction in London. I'll be bringing my daughter when she's born 🤣
Finally got some time to sit down and enjoy this. Every video is such a treat. Thank you!
that reed switch thing is the kind of secret knowledge we need Tim :D
Cylinders used to come with tie bars, reed switch could bolt to them.
@@flybobbie1449Still do

Nice to see you here Mike, it's a small world I guess
A Tim & Mike collaboration would be fascinating...
Or compressors from used fridges and A/C units - They can be used either as a compressor or as a vacuum pump.
However they won't last long without proper lubrication applied directly into the intake air...
Great to see you back, I remember your TV series when we were all younger, and have loved your practical approach to passing on your knowledge and experiences ever since. Thank you...
Could watch these all day. Thanks Tim 🙂
This man is a national treasure
One word sir, BRAVO! At the end of your videos I feel I have a PHD in the subject at hand. Thank you for the work and works you have done.
"Intermittent faults are always the worst"
I live by these words.
The bane of the electronic engineer
Bucketlist; visit his museum of oddities, loving it!
It is on my list too - this year hopefuly.
Wow, I had no idea you had more shows out! I have entire series of The Secret Life of Machines saved! As soon as i finished watching, I donated!
I'm a Machine Operator at a factory and Pneumatics are used *extensively* both on the machine I run and elsewhere in the facility. They even have air-powered pumps called 'Sandpipers'.
it's a good day when there's a new Tim Hunkin video
More please! 30+ years and still a joy to watch.
You remind me so much of my grandfather. He was so smart and always in his shop devising clever devices of all sorts. He built a elevator in his house in later years and used paddle wheel pump and cold creek water to cool his house back in the 40's.
I don't even wait for the video to finish before hitting the thumbs up button. All Tim's videos are thumbs up worthy!
so good to see Mr. Tim Hunkin continuing the series. Thank you.
I could have done with this back in 1980s when I did pneumatics as part of O Level D&T. Great stuff!
8:35 Oh my I remember playing that one in London last year during September! I still have the 'nuclear waste' as a memento to the wonderful time I had. Thank you for your service Tim. Greetings from Germany!
Dear Tim, it's so nice you're back ❤
My favorite TV personality as a kid is now my favorite TH-camr as an adult. Can’t get enough!
Secret Life Of… still one of the best series on “television”. Wish you had been one of my teachers at school.
As a child, I loved Tim and Rex in The Secret Life of Machines.
As an adult, I'm in disbelief the YT algorithm did me such a solid as to show me this great man is still at it 35 years later!
Wonderful to have you back Tim! We've missed you 😃
Brilliant video! Makes me want to play with these things. Thank you
When I grow up, I want to be as awesome as Tim Hunkin.( and so does my son!)
Thanks Tim, we all truly appreciate the effort you go to sharing your knowledge.
Can I just say - you are an absolute delight Tim! I truly love your work.
A genius. Lucky enough for us that he lives in Suffolk. Rex Garrod and Tim reflected true English inventiveness with that edge of strangeness! Rest in peace Rex, but long live (Sir) Tim!
Thank you Mr Hunkin for sharing your knowledge and experience, and for filling the world with your unique brand of mechanical humour.
Sweet a new subject!!!! Absolutely love they way you do these videos,thank you for all the info and entertainment!

I would love to take the mantle, in due time of course. I still have a ton to learn but we need more people like Tim Hunkin in this world!
A great pleasure to see what really works and the reliability of different systems. Decades of hands on experience. pure gold. Thank you Tim.
Nice to see you back Tim, absolutely love this series, old and new. Thank you so much for sharing, hope you're keeping well

I never forgot the few episodes of Secret Life of Machines that I saw in the 90s. This is a delightful blast from the past.
TIM! I am overjoyed by your return.
I cannot express my appreciation to you for making this video enough. A million thanks good sir.
This is the crash course into pneumatics I needed. Thank you for putting in the time and effort to share you knowledge.
Ah, a new Tom Hunkin Video! The Magic of Your Shows are Still There! You are the Common-Man's Treasure!
I have been watching and following you since I was a young man, and we are kindred spirits in Tinkering!

Hi Tim, thanks for making a new series. Such a brilliant deep dive into pneumatics, I didn't know they came in such small packages 🙂
Thanks for putting these videos up, very informative and inspirational. The 55 minutes of the video just flew by, thanks for putting this online.
Great to see new episodes in my feed. Thank you Tim.
Many thanks Tim. You were and continue to be an inspiration and great educator.
The best series on YT!!! Nothing worse then trying to figure something out and the yahoo that your watching has never done it before
I learned several things I will utilize in my projects. Tim, your videos are an example of what TH-cam should be!
Fantastic! Some I knew, lots I didn't. Great tips too. Still educating me after 30 + years, thank you 😊
as a professional mechatronics engineer I find this series of videos incredibly educational and what's more explained in very simple terms and practical. Thanks a lot for sharing your vast knowledge!! very cool arcade machines too!
Yay! Great to see you back with more :)

Thanks to you and TSLotM I've understood how refrigerator works. Now I'm nearly 40 and still watch your videos on YT. Best wishes from Poland.
Tim glad you are back. Absolutely made my day. Having a very hard time through bereavement and just rubbish work but this made me feel so full of happiness. I work in oil and gas, it’s all about control.Glad to see you doing what is brilliant… Love A xxx
Superb, thanks Tim. Let's not forget the pneumatics that Rex used on Brum and his robots, all very effective.
Thanks Tim. I'd not really thought about pneumatics for a long time. I had some pneumatic lego when I was a kid but that's really the only time I've played with it. Maybe I'll start using it in some projects now your video has refreshed my memory of it.

Electro -manuafcturing will be a great career and I would include learning to code aswell and you will never be out of a job :)
"All calls are charged at 1 Pound per second sounds about right". Cheers for the great content Engineer Hunkin!
Happy 2023 Tim, from an Englishman making armour in a French forest.
I just downed tools for this... and that is the rule! 🇬🇧⚒️🏆
Thank you Tim, these videos are simply brilliant, a goldmine of information
Great to see you again Tim, very informative...... thank you so much I always enjoy your videos 😀
Tim. I think you’re somewhat unique on TH-cam in providing not just a high-level how to but also a semi complete survey of the equipment involved. It is awesome! I was voided using pneumatics for years and having watched this I feel confident to be able to launch into my own projects. Thank you.
Thank you Mr Hunkin for such great content, ideas, and creativity!
Yes! Thank you, Tim. You're a legend.
Yes! It’s here! Clicking like before even starting because I have no doubt.
Love it! Thank you so much, Tim! The world needs you.
Quite literally one of the best channels on TH-cam.
I love your arcade machines, I haven't seen anything like that here in the US in a long time. Wonderfully creative.
Very interesting and informative. As you always have been!
this was fantastic, thank you! I especially appreciated the break downs of equipment with clear video and short explanation.
Fabulous! Such a joy to watch for knowledge, ideas & inspiration. Thank you for sharing!
in all sincerity tim...
thank you for your works sir.
it's been a pleasure to have followed your builds through the years.
thank you for the continuity. such things are priceless sometimes.
=dok=
I recognise that carpet in the background from about 25 years ago! 😁 Some hip dude and his friend was demonstrating vacuum cleaners on it! 😂
If you want to check out low pressure pneumatics, look at the W123 in your drive! The central locking is all vacuum powered. You'll find a huge vacuum tank at the top of the boot, and lines going to all the door and the fuel filler. A valve in the driver's door is connected to the lock plunger, and switches between 2 vacuum motors like the VW one you showed. There are other similar ones in the dashboard for the HVAC to move the blend doors.
On an old diesel Mercedes there's a valve connected to the accelerator linkage which simulates a gas engine manifold vacuum, for the automatic transmission. I've taken mine apart, but still don't understand how it works. It must operate on a similar principal to the pressure regulator, but I don't see how it doesn't create a vacuum leak. My 1991 Benz adds to this a vacuum amplifier device which modifies the accelerator vacuum valve with boost pressure. The ignition switch is pneumatic too!
Tim thank you so much for making these videos! Greatly appreciated!!!
An absolute masterclass. Loved every minute. Interesting I noticed because Tim is left handed I could imagine myself (right handed) handling the pneumatic tubes etc as he demonstrated their workings. I think I might wear my red boilersuit next time I watch. If only I really could be the wonderfully imaginative, artistic, amusing, engineering talented Mr Hunkin!
Tim is an absolute legend. An artist of the highest caliber. He takes the term industrial arts to it's most literal interpretation. :)
