Hello all! I don't know if this is in the right place or not, but it's quite an outlandish topic so I'm gonna assume this is right! The pneumatics system has gone through many part additions and changes over the decades. One component that never showed up is the hydraulic motor. Now, I'm aware that hydraulics and pneumatics are very different things, but the operational differences would fade in higher speed applications. What I mean by that is if there were to be a very high speed (due to the differences in how air and liquid drive these motors) gear type or axial piston type motor for example, and you coupled them to the existing planetary gear trains found inside most PF motors, the results in theory would be fairly decent torque and roughly normal lego motor speed inside of a roughly lego motor-sized housing. So why haven't they done this? And how come no one else has done it on the internet so far as I've seen? I know you can make rotary motion using pistons in an "engine" application, but that method has some obvious limitations barring it from actual use in an MOC usually due to size and/or switching inefficiency. Let me know what you all think of this as an idea, and fill me in if you know why this wouldn't work in practice if it doesn't! -
Hello After watching this I started to wonder if it was possible to build it with Lego and after some research I started building.IMG_0642 by JJ2Sam, on Flickr The engine is extremely simple with only two holes in the piston housing allowing air in or out making it robust to use. Since it is only a single cylinder it uses a flywheel to keep the cam rotating. IMG_0640 by JJ2Sam, on Flickr Unlike internal combustion engines found in your car where the piston is in a rigid housing or block making the piston have to have a ball joint allowing it to travel up and down this engine allows the entire piston and housing to rock or oscillate. IMG_0641 by JJ2Sam, on Flickr I have made instructions A ReBrickable parts list will be made. Thanks for reading. -
Flameo my fellow Avatar fans, I’m a huge fan of ATLA and I need your help. Recently I have submitted a project on LEGO IDEAS, it's the Spirit Oasis from Avatar: The Last Airbender. As you might know LEGO IDEAS is a website which allows users to submit ideas for Lego products to be turned into potential sets. So If my project reaches 10.000 supporters it may become an official LEGO Product. Many Avatar Fans including me would love to purchase another LEGO ATLA Set since the original sets from 2006 are not available anymore. Check out my project: The Spirit Oasis Project on LEGO IDEAS All you need to do is press the support button and create a free LEGO Account if necessary. Thanks a lot, Every supporter counts! -
Hello, I have been recently wondering "How can I make fast air with my pneumatic pumps" I have built a fully functioning, belt driven system which turns the pump at a hell of a speed already, it can go even faster by adding a smaller pulley, but I didn't incase the pump got caught up and snapped. I was filling my air tank up with it, the pressure got so good the pipe popped off the air tank, it filled within 3 seconds, with a small grey pump. I have produced this setup out of a powerful RC motor and meccano and a thick belt and 2 pulleys. I had drilled a hole into a flat circul and attached it to a shaft as an offset gear which drives the pump. If anyones interested, I will take a picture.

For my final post of this year, I am proud to introduce the Range Rover Evoque with air ride. Thanks to all for the comments and suggestions in my WIP thread to create a better SUV. The car was too black so I added white, it was too low so I raised it a stud and the hood wasn't slanted enough so I re-created the front of the vehicle. I reduced the weight to 6.3 pounds (2850g) This car has 4wd, air ride, torsion bar suspension, 2 XL motors for drive, 2 m motors for lift, V8, servo for steering, gear shifter turns on the lights. The car is finally to a perfect scale. The hard parts of this build was the air ride, torsion bar and having the doors start low at the front and higher at the back. I bought a pair of custom chrome exhaust pipes for this built. flickr: https://flickr.com/photos/139930963@N04/sets/72157676733470861 MOC-Pages: http://moc-pages.com/moc.php/435565 Instructions: https://goo.gl/photos/KLwkEfTt2LzsRMkG8 Inspiration: Inspiration by lachlan cameron, on Flickr Below is the car in comparison to the 42052 helicopter set Air ride Range Rover Evoque by lachlan cameron, on Flickr Back end was super difficult: Air ride Range Rover Evoque by lachlan cameron, on Flickr Everything opens: Air ride Range Rover Evoque by lachlan cameron, on Flickr Front View: Air ride Range Rover Evoque by lachlan cameron, on Flickr I'm ready to take my helicopter to work...

Dear all, For the pneumatic contest, I've built a huge robot called ''Nemesis''(from the ancient greek goddess) and I would like to share it with you. Nemesis has 22 pneumatic functions operated by a double compressor. All pneumatic valves are operated only manually according to the competition. Has a weight of 8kg and consists of 8000 lego technic bricks. Total air cylinders : 26 large 11 mini The compressor uses 2 large pneumatic pumps operated by a PF XL motor. The maximum pressure that can be reached by this pneumatic system is 28 psi with fresh batteries. Due to more than 30 pneumatic ''T-air pieces''pressure cannot reach a higher level because there is a huge drag and the XL motor has no power to rotate more. The length of pneumatic tubes are between 0.5 and 1.5 meters long. Due to the large hoses, large air storage is needed because there is a lot of air loss in the system. The air of the whole system is stored inside 2 lego air tanks (although the system needed far more) : The compressor has an auto-pneumatic switch using a large cylinder, which turns the air engine off when the pressure reaches 24 psi. A manometer is used for showing the air pressure at any time. Functions : Nemesis has 2 arms. The bigger front arm has 15 pneumatic functions and the small back arm has 5 pneumatic functions. The small back arm has the following movements : a) small gripper b) elbow1 c) elbow2 d) shoulder e) shoulder rotation The huge front arm has the following movements : a) large gripper, operating 10 fingers independently having 2 mini cylinders each b) wrist, operating 2 functions (up-down and turning) c) elbow d) shoulder e) shoulder turning Besides, the robot has 2 more pneumatic functions : 1) Face movement 2) A third gripper which is mostly for fun (e.g. for scaring house cats) Here is the video of the project : Thanks for watching Good luck to everyone! -

I wanted to create some different areas based on the four elements represented by the four main elves, I've mixed parts from all kinds of different sets to create these places. This one is the earth themed home for Farran the Earth Elf. I wanted it to be part cottage, part treehouse. It's mostly parts from The Elves Treetop Hideaway and the Ewok Village sets. I attached my waterfall cave alongside the treehouse I also made a fire themed volcano cave with a tall treehouse/tower neighbouring it. It's mostly made from a Lego Friends set that has a cabin and a waterfall. I kept the cabin and built the tower above it and changed the waterfall into a volcano. I've created a workshop for the Air Elf Aira in one section of the tower with a bedroom above it, an observing platform with a telescope above that and a turret room on the top. The webisodes show that Azari the fire elf is homeless and just crashes with the other elves, but I've given her a warm place to sleep inside the volcano. I kept the camp beds in the cabin for the humans to sleep in when they visit Elvendale. And here's some random pictures..

Hello everybody, I am glad to introduce you my last big project : a pneumatic steam locomotive ! I think it's one of the firsts pneumatic locomotives, using only Lego parts. First of all, the YouTube video and some photos: The idea with this model is to replace the steam of a real Locomotive by compressed air, and this for as much functions as possible. Here are the main functions : Movement of the train : Using 4 pistons, 2 on the sides, and 2 inside, the train can move forward. It works like a classic LPE, with 2 pistons shifted 90° from the others. 4 pistons consume a lot of air, but they guarantee enough power to move the whole train. To make the rotation smooth, a free wheel is hidden inside the boiler part of the locomotive. Its rotation is 25 times faster than the wheels of the train (40t/8t x2). The train isn't moving very fast because the pneumatic elements aren't modified. However, it's fast enough to make it interesting to look at the connecting rods and wheels moving. The breaks : On a real locomotive, compressed air is produced by a compressor (powered by steam) and is used to press some brake shoes against the wheels. Here, the same technique is used : a small piston is filled with compressed air, and thanks to some rods, brakes shoes are pressed against the wheels. It's cool but...it's not enough. Plastic against plastic isn't very efficient to stop the train's movement. Therefore, another rod is connected to the brake system and press another brake shoe against the free wheel. Because its rotation is faster (and therefore, with a low torque), it's is way easier to stop it. The Whistle : A system that I love in this locomotive is the whistle. Currently there isn't any whistle produced by Lego that could be used in the locomotive, so I had to think a little for finding something working. This whistle is activated by a switch in the cabin. The Cabin : Nothing much to say except that in contains 3 switches for the 3 main functions (whistle, wheel movement and brakes). There is also a pressure gauge showing the pressure coming from pumps. The train moves with a minimum of 1 bar. A 2-2.5 bars, the movement is faster. The air supply : There are several possibilities for the train : we can directly pump with Lego pumps, or store the air into 6 to 8 airtanks or produce the air with Lego motors and small pumps. For instance I use 4 pumps side by side, linked to some air tanks, but I don't what the final model should work. Maybe some motors and pumps could be cool ? The design : The hard part was to make the boiler of the locomotive. It's a little hard to make cylinders with Lego technic parts but, with flex axles passing through Technic beams, I managed to make something satisfying. Some details are visible on the locomotive, I tried to make it look a little crowded like a real locomotive with fake air/sand tanks, fake compressors and mechanical elements. It's probably possible to make it look better, but for instance I am happy with it. The rails are "homemade" with Lego bricks. The locomotive is too big of course to work on Lego railtracks. The wheels aren't perfectly flat so the train is "blocked" in position inside the rails. Therefore, the train can move foward cur cannot go out of the railtracks (which is great for a train). Finally, as a bonus functions, there are some bumpers at the front and back of the locomotive to imitate the real bumpers used to absorb small chocs on a Locomotive. That's it for now, I hope the model is interesting to you and if that's the case, don't hesitate to support it on Lego Ideas !

I was always dreaming for creating my own quadcotper/Drone,I am so glad to share with you my X-Drone design which I spent a lot of time to do it. The design was built in many stages to fulfil the Aerodynamics ( as shown in last picture ) and to be as light as possible. I believe a video will be much better than writing a lot :) LEGO IDEAS Link ( Please support me if you like it ) https://ideas.lego.com/projects/f51a1d5b-9fd3-4356-ab59-af97c52eb0fa Kindly check my video on the following : I always fail to have good support in lego ideas so I really need your to give me your opinions and what i do wrong .... Your comments & Supports will help me a lot... Thanks for sharing your feedback with me. More Pics that I like : -
I was looking for LEGO Concorde designs but not very much came up in such a small scale so I thought I might as well give it a try. It comes complete with bendable nose cone, retractable landing gears (front and back), moveable back wing flaps (thanks again, mini fig pants...!) and the optional flame FX for... historical accuracy... . . .!? And as always you can find more pics here and if interested in a cutesy little Concorde to swoosh around the full set & instructions are available here. I hope you like my small sized interpretation of one of aviation history's most iconic aircraft. Thanks & have fun! (And many thanks to ukbajadave for explaining to a noob how to implement more pics here!) -
Hey guys, During a chat I was pointed to the Steinwinter Supercargo 2040. I was fascinated by the look and decided to build it. It was designed by the german engineer Manfred Steinwinter. During my research, I found out that he build only one prototype, but planned many more versions. I liked the three-axled version and so started with a rough sketch to get an idea of the proportions: While I was searching for images of that truck, I also contacted the current IP owner and asked for blueprints. Fortunately he liked my project and he send me some. Since then this truck went through many iteration of improvements and design changes. In the end I decided to use Powered Up to control it. This is the current state: These are planned/implemented features and specifications: Current weight: 3kg Length: 86 studs Height: 14 studs Width: 27 studs Power supply: 4x Technic hub Driving: 4x C+ XL motor, each motor is connected to one hub to spread the load (3,528:1, theoretically 0,74 km/h @7,5V @124Ncm) Steering: 1x C+ L motor, two steered axles with Ackerman geometry Compressor: 1x C+ L motor, 4 pumps 3 RC valves: 3x C+ L motor, 3x newest valve one for each the rear axle, front/middle left wheel, front/middle right wheel Angle sensor for suspension on front and middle axle: 2x C+ XL and 2x Boost Medium motors OR 2x C+ XL Angle sensor for rear axle: 1x motor (not implemented yet) Air/pneumatic suspension on all axles controlled by Powered Up double wishbone suspension on fron and middle axle Each front/middle wheel on the left and right side are one unit. That means if the front wheel is pushed up the middle wheel is pushed down. That way the weight is equally distributed on the wheels live rear axle When I decided to use Powered Up I thought about controlling the ride height somehow with Powered Up. To do that I needed something to read the position of the double wish bone arms and the rear axle. Since several motors in the C+/Powered Up eco system can report their position, tried to use them to read the angle of the suspension arm. I successfully implemented that on the front and middle axle. For the rear axle I haven't found a good solution yet, because that axle can move on two axis. While I'm waiting for some additional parts, I'm working on the solution for the rear axle. As for the code, I already made a proof of concept. I created a test setup and wrote some code, which reads the angle of a suspension arm and adjusts it to the desired value. for the finished MOC a can think of something like a parking height, highway ride height and more or less off-road height. Once the chassis is finished the and the Powered Up is working I'll start working on body. Feel free to leave comments, critique and suggestions. -

Lord Sam Sinister is in a evil partnership with Lord Ogel, dictator of the industrial country of Vladeck. They are currently (as of January 1925) scouring the world for an artifact named Poseidon's Trident, with the latest lead having them head for the southern tip of South America. Sam is accompanied by his personal battleship named "Sinister Purpose", two diesel-powered submarines, a new series of stealth aircraft and a small battalion of troops and land vehicles. He also has all his underworld contacts, including but not limited to: Senor Palomar, Alexis Sinister, Barron Von Baron, Max Villano, and more, ready to help him with his quest. Lord Sam's mission is to find the Trident and with it, help Ogel conquer the seas (and the world). His only real opposition is Johnny Thunder and his friends Major Quentin Steele, Jake Raines, & Pippin Reed, plus their small fleet of vehicles. This is Sam Sinister's personal battleship, the "Sinister Purpose". It features two anchors, three smokestacks, and four turrets. I have given the turrets the ability to move the triple-gun barrels up and down and swivel side to side. (In the real world, this battleship was originally designed for my brother, Austin, who later discarded the project.) Here is one of the two identical submarines used by Lord Sinister and his forces. This one is named the "Red Fox", while the other is named the "Black Wolf". (In reality, this submarine was gotten from Brickshelf back around 2011. I don't remember who did it, but it is Studs Not On Top, also known as SNOT, for 90% of the build.) Here is the LDD file for both submarine and battleship: http://www.mocpages.com/user_images/80135/1426187247m.lxf This prototype stealth aircraft is nicknamed "The Stalker" for it's ability to creep up on a target and follow without being noticed, before it blows the enemy craft into oblivion. (When Indiana Jones set 7683's (Fight on the Flying Wing) pictures was first leaked in dark grays, I was impressed... but then they went and changed it to dark green in the final, released version. Well, now I changed it back! I removed the unavailable parts, turned the regular green and dark green to light and Dark bluish gray. The cockpit is no longer hinged, making it much stronger, plus the rear guns no longer swivel, eliminating that weak point. The cockpit is supposed to be the Star Wars Jedi star fighter dark-bluish gray-print-on -transparent-black part) The fleet of vehicles at Sam Sinister's disposal includes two dozen fighter aircraft. These fighters are not as advanced as the flying wing above, but still can hold their own against almost anything thrown at them. (This model was originally set 6745. (Propeller power) I turned into that micro scale model into a plane that a mini-figure can sit in. it was turned from red, white, and yellow into a slew of military-looking grayish hues.) LDD file for the aircraft here: http://www.mocpages.com/user_images/80135/1426185143m.lxf This fearsome piece of machinery is used to cut down trees in the path of the land forces. It is currently being heavily used in South America as the search for the Poseidon's Trident grinds on in the Amazon Jungle. (I bought the original set 7626 (Jungle Cutter) in Summer 2008. I wanted to make it it in dark gray to match my two trucks but gave up after trying to order the parts from Lego. (I didn't know about Bricklink at that time) Well, now the shoe is on other other foot and here it is, in full grayish glory!) Here is a fuel supply truck of the convoy currently running back and forth from the battleship Sinister Purpose to the head of the group pushing further inland. These trucks are the weak point of Sinister's forces. Destroy them, you halt the progress towards the Trident. (This model is almost a stock part of 7683. (Fight on the Flying Wing) I simply redid the rear tank to keep it from spinning.) These trucks may be empty now, but usually they are filled with troops protecting the convoy searching for the Trident. (These are made from 7622. (Race for the Stolen Treasure) Since the fabric part is so VERY expensive, I found a solution in the Eurobricks Official sets LDD topic. I took the cover from the trucks built by user ADHO15 and redid some portions to be cheaper (I.E. thinner tires) and better coordinated color-wise.) This vehicle is one of many used by the forces of Evil to search for Poseidon's Trident. This particular car usually holds an officer of the Vladeck Armed forces, Special Recovery Division, which looks to capture objects of power through less-than-legal means. (The car seen here was originally part of set 7622, Race for the Stolen Treasure, as the machine gun hauling support vehicle. I have put a roof on it and turned it into a officer's car.) Here is the LDD file for the land vehicles: http://www.mocpages.com/user_images/80135/1426185434m.lxf Johnny Thunder will need to bring his A-game to stop Sam Sinister this time. Comments, questions, and complaints welcome! -
Here is my first-ever render! However, since it is sci-fi, I post it here, right? I looked around and that seems to be correct. If it isn't, I apologize admins! Behold, the Indomitable Rush! This ship blatantly steals ideas from both my Man-o-war airship and my Manticore mech. But the end result, I think, still looks original.

current: the bodywork was the downfall of this car, i do better with gaps and holes. the chassis is my strong point, bodywork is not my strong point with legos. dont expect an update for a few days. this car will not have instructions. sorry i disappoint this time, this next car i have good experience with the bodywork for. a insight: this is not my only project...... le mans... prototype...... power functions..... concept: Air Pocket this is my project i have been working on the last 2 days, project Air Pocket. the aim of my current project is to make the most light, easy to make, simple, and durable car i can. the current car has a simple Rwd, hog, setup. those work fine, but not enough. the plan is to finish before the 24h le mans race, or on that day (17–18 June 2017) as a car to celebrate. some photos.. suicide doors.. for now.. underbody. it is not final of course, just a test chassis. color vomit is there on inside as much as possible.
