  3. Hey, Eurobricks! It’s been a long time. And for me it’s been a really tough time. Actually I’ve been suffering from anxiety disorder and OCD for a long time. It seems I can just handle it and not let it affect my life (which I did also for a long time) but things got out of control in the past few months. It’s the darkest time in my life and basically I lost interest in doing anything. God knows what I’ve been through. Luckily I got my family with me all the time. More importantly I didn’t do anything bad & stupid to myself. It is still a recovery process for me, but I think I’m well enough to pick up some unfinished LEGO projects, something I love to do, and something that will make me feel better. So today, I’m bringing you one of those projects - a LEGO version of the SHERP ATV. Parts count: 1374 pcs Weight: 1420 g Dimensions (Length x Width x Height): 232 mm x 195 mm x 178 mm / 9.13 in. x 7.68 in. x 7 in. Exterior I like this kind of compact vehicle, especially with massive tires. While building this model, I have a single goal for the exterior: full enclosure. It all started with the mudguard. I tried to use Technic parts to build the middle section but it’s nearly impossible to recreate the curves with no gaps. So sloped bricks become the best choice. To compensate a little bit on the extra “unnecessary” weight, the enclosure is also used as part of the gear housing. Drivetrain Instead of putting two identical motors on each side and making it skid-steer drive, I decided to make a drivetrain based on a subtractor. It made precise steering possible, and can be controlled one-handedly by Sbrick, which something I prefer when I drive the model while holding the camera on the other hand. This is a prototype: It’s a failed attempt. Knob wheels not only cause unsmooth power transmission, but also take the space of a 5x7 frame, which is supposed to be a sturdy housing for the lower differential. As a result, the lower diff got damaged from gear slipping after 5 minutes of test drive, the whole model couldn’t move completely. After several tests, I replace the knob wheels with 16-tooth clutch gears. it only introduces very little frictions and it’s very reliable. Here is the final version: Performance I made a short video (4K): More Details Hope you like it. Feels good to be back
  4. Hi, another Mini-MOC for you: here comes the Mini-Skidder This little thing is very powerful as it uses 2 L-Motors for drive and a third L-Motor for steering. Watch the video: On my brick safe page you can find the pics in higher resolution and of course an LDD-File: https://bricksafe.com/files/Leonard_Goldstein/woody_and_the_woodpicker/Woody-Woodpicker_V02.lxf Let me know what you think Regards Leonard Goldstein
  5. Hello Eurobricks AFOLs, I am Engine and this is my first post here on EB forum. My friend HorcikDesigns told me, some of you here want to know more about my last MOC. My pleassure! Original Vehicle: As some of you noticed, my MOC should be scale model of Ghe-o Rescue. It is a Romanian rescue vehicle designed for extreme terrain, with a capacity of up to 11 people. Dimensions are: 5.2 m length; 2.7 m width (even wider version exists); 2.4 m higth (without rooftop carrier). The weight is 3.2 tons. Under the bonnet, more engine types can be monted, with the most powerful one with 500 hp. Live axles are used for suspension, both equipted by lockable differentials. There are also built-in water tanks for 620 liters for fire extinguishing. Another specialty is the possibility to mount tracks to rear wheels or pneumatic "pillows" on wheels for floating on water. Tires are also special. It is Arctictrans 1300x700-24 (diameter 1300 mm and width 700 mm). The manufacturer shows off an independent test in which they won over Avtoros and Trecol manufacturers. Here you can see several cars built on them. And because the tire diameter and width exactly match the 1:16 scale to the LEGO "Tumbler" tires Ø81.6x44, the scale of the model was decided. So far I do not know any other LEGO cration of Ghe-o Rescue. MOC: The MOC was designed for Kostky.org Trophy Competition, organized by our technic race event guru Peter. And the task was to build a drivable, remote-controlled, off-road vehicle that would be able to travel about 3 km. And at the same time, it should be as beautiful as possible and with design matches to original vehicles. Terrible task. The dimensions of the model are: 332 x 168 x 168 mm (41.5 x 21 x 21 studs), weight 1.2 kg. The drive is permanently 4x4 without differentials. Axles are not sprung. But thanks to the torsionally soft frame of the vehicle, decent axle crossing is achieved (some LEGO trial experience here). Inside, there is a functional winch with a length of 2.5 m. Good lighting is a necessity for the expedition special. The control is provided by sBrick. The propulsion is made by 1 x PF XL motor with a total gear ratio of 1: 1. Schizophrenic steering is provided by the PF Servo. The winch is driven by a PF M motor via a worm gear (8: 1 ratio). Five pairs of PF lights really shine in front of the car. Electrical source is a battery box with 6 AA batteries. The whole MOC is pure LEGO exept of: sBrick receiver, high strength thread as winch rope, threaded cardans and event mandatory stickers. Drive ability: Drivig speed corresponds to a pleasant walk. Off-road capabilities were adequate to the track. Tire traction did not limit offroad capabilities, but a small power of e-motor did. Then the winch becomes useful, that is able to lift the entire weight of the vehicle. And if it was still not enough, the other "competitors" were there to help. A minor issue was the steering. Thanks to the loose in steering mechanism and occasional insensivity in the mobile app, sometimes I sent it out of the way. A major issue was energy consumption. Within 1.5 km, I drained out three sets of batteries (2x alkaline GP Ultra Plus, 1x rechargeable GP 2700). And yet I do not know how to solve it. But most likely it is caused by PF Servo motor, as we disscussed after the event with other partipiciants. ----- Thank you for comments and questions. Pictures are here in my gallery. Original post on Kostky.org.
  6. The 42065 RC Tracked Racer is a nice canvas for modding. I was a bit disappointed when I found that it didn't have any technic gears apart from what you find when you disassemble the motors. Technic has always been used to teach mechanics to kids, and I personally find differential drive to be a super interesting alternative to the direct drive approach. It didn't take more than a couple of hours to stuff in a couple of differentials, so I made a little video of this mod in action: Another obvious "MOD" is to SBrick the model. This is a ridiculously simple MOD, so I decided to document the whole process of unpacking, updating, and programming a remote using the SBrick: I also had super high hopes for the L-motors. Perhaps this would be more interesting with a 2:1 gearing for double speed. This is how the standard direct-drive model performs with L-motors: Next up will be a GBC-module built mostly from parts of the model. To make a plain belt drive module is not really interesting anymore, so I'm currently trying to figure out if it can be made more interesting.
  7. Hello! My latest MOC is a re-creation of unusual Jeep model. Jeep Mighty FC Concept -Weight: 2125g -2 XL motors for propulsion -Servo motor for steering -M motor for 2 speed gearbox -M motor for locking rear differential -M motor for winch -3 LEDs for front and rear lights -2 SBricks powered by one rechargeable battery box -Portal axles -Openable doors and tailgate -Shallow bed with fold-down sides -Detachable roof -Alternative tube doors The chassis is not realistic, but has decent offroad capability as heavy Lego model. My goal was to make a sturdy and powerful crawler having propulsion motors and gearbox on the center of its chassis. Which means the drivetrain contains two universal joints - weakest points - for transmitting the torque to front and rear live axles. To save U-joints from damaging, I adopted two stage reductions after differential on both axles. The gearbox is similar one to my previous FJ40 Crawler. I doubled the pair of 8T/24T gear for higher durability. High gear is three times faster than low gear. You may wonder why rear ball joint is connected lower than front. That is for avoiding body roll caused by high torque of hard-coupled XL motors. Seeing from the gearbox, the rear output rotates in opposite direction to the front one. So the front and rear axle are equally forced to rotate in opposite direction to each other. Thus the center chassis with heavy body does not easily roll left or right even when climbing steep incline. (...at least on paper. I admit the complete body is a little bit too heavy to prove the theory above.) Steering angle is good, but turning radius is not so good. Because of the lack of center differential, it cannot handle different rotating speed of front and rear axle in tight turning. On slippy surface, like in the video, it can be steered without any problem. Rear differential can be locked instantaneously. The role of 8T gear on top of red changeover part is to make a tiny gap between 16T clutch gear and driving ring in locked position. Thanks to the gap, 16T gear is not pushed against outer structure. That helps to decreasing the friction. Front winch is powered by M motor geared 9:1. I used two pairs of 8T/24T gear instead of worm gear. It is smoother and surprisingly powerful. The hook can be manually pulled out by switching the lever under right seat. The body looks a bit squarish comparing to the real Mighty FC. Maybe I could replicate trapezoidal shape of its cabin. But I thought angled pillars and roll cage would be wobbly. So I decided to build simple yet sturdy. Instead of realistic appearance, I managed to realize easily detachable roof and doors. Although the whole MOC is built for using Unimog tires, Claas tires also fit well. But the maximum articulation of axles would be smaller because bigger tires possibly touch the chassis and fenders. It would be necessary to limit suspension travel or slightly modify the chassis. I hope you will like it! I will make building instruction. But I have to finish the instruction of Pickup first.
  8. Hi, My latest project is not a Lego creation but an Android app that lets you control the SBrick with any Android-compatible game controller. Here is a short demo video on it: Please note that it's not available yet since it's still in WIP. Current features: - Works on Android 4.3+ devices supporting bluetooth low energy profile. - Basically works with any type of Android-compatible game controllers (I'm using a cheap one from DX). Leftovers until I release the first test version: - Profile editor is not yet finished. - Stability issues. - Minor UI updates. Any comments or suggestions are welcome :)
  9. Hello! I’m not particularly proud of this Technic horror I’ve created, but I’d like to share it with you rather than keep it to myself, possibly forever. Shortly after I learned about (and supported) SBrick and MiniZip in KickStarter, I started dreaming of building powerful, compact MOCs using a new combo: PP3 NiMh battery + MiniZip + SBrick + 5292 RC Buggy Motor. This is my first attempt at it, now that Android SBrick app (1.3+) is finally usable Functions Drive: 2x 5292 RC Buggy Motor, each connected to a separate SBrick, each powered by a separate PP3 NiMh 250 mAh battery using MiniZip. Steering: PF Servo. Front suspension: independent, soft, long travel, with “fake” positive caster Rear suspension: solid axle, dragged (didn’t figure out how to do four-link) 4x Lego LED Still haven’t applied myself to learning proper bodywork, so designing my own was out of the question. I went for an easy, fairly plain one. No openable doors, bonnet or anything. I worked with these two photos and scaled for 62.4mm tires. Full size (> 1024px): 1, 2. Photos were made really quick, during a baby siesta (indoor) and in short incursions (outdoors) no more than 20 meters from home. For now, I can only dream of having more time and freedom for this :D v0.99 without stickers: v1.0 with stickers based on video: Old school navigator refused to deal with GPS and computers, wanted just a compass (70001pb02) and a map with an X that marks the spot. Smart dude, run off with the loot. Very short of creativity and sleep, the only alternative I could think of to get rid of the demonic Monster logo and brand was a rather lame one: Music Energy. Example diff: I asked friends to vote in G+ and 3 out of 4 prefer Music, but the one who prefers Monster is my the only one into LEGO. I’m divided, will probably print them and try them on, but still not sure which ones to use for filming. I started with 1 battery, 1 SBrick, 2 motors. It seemed to run well. Adding an extra battery and Sbrick seems to make it run even stronger / faster, although SBrick developer Zsolt Majoros said it shouldn’t matter. The real reason I added the extra SBrick is that “2 ports 1 function” only works in Android app when those 2 ports are on separate SBricks. You may ask why use PP3 batteries instead of the acclaimed LiPo batteries… mainly because they are expensive, and a bit of a lottery with their thermal protection. MiniZip + PP3 NiMh 250 mAh wasn’t a whole lot cheaper, but the combo is certainly more compact, half the weight and doesn’t have any thermal protection. SBricks can draw as much current as the motors want, with just a small risk of overheating and possibly catching on fire… ah well, what could possibly go wrong? I haven’t actually managed to make the batteries warm up, they get warmer when charging. One likely reason for not achieving hotness is short life, according to this battery life calculator, they’d last 3.5 minutes at 3 A, 10 minutes at 1 A, 20 minutes at 500 mA. Can someone make a better-informed / estimation of a more realistic battery life? But there are more and worse problems, for which I sure can do with your advice! Caster angle is fake, isn’t? I mean, I just shifted the upper A arms a half stud backwards, but both A arms still move vertically. I think this is why big bumps will throw the truck’s front up rather than only the front wheel/s going up. When hitting a big bump with a front wheel, the wheel will thrust up and with it the whole car will roll to the opposite side. This results in a raised rear wheel taking all torque to just spin in the air, so the car stops until the raised wheel hits the ground again. Shifting the upper A arms a half stud backwards messed with the steering geometry, so now there’s a not-so-slight bump steering. I think this, combined with the twisting effect on the solid axle, is what’s causing the truck to steer to the left when accelerating. Too bad. Motors are hard coupled on their fast output and then geared down 20:12 twice, not including the 20-tooth to differential connection. Maybe I could / should gear down 20:12 only once, haven’t had a chance to try yet. I suppose integrating the motors in the rear axle and connecting wheels directly to them would help with the last couple of problems, but couldn’t figure out how to fit that in this body just yet. I’m also concerned that if one battery drains faster, the motor (no longer) powered by it will get damaged. With each rear wheel directly on one motor, that would result in the truck going in circles, but motors wouldn’t get damaged. How bad is this? Steering with SBrick (v1.3) as a significant latency, in the time it takes from the moment I slide my finger to a side (much or little) to the moment when the PF Servo starts moving, the truck is already going the wrong way. It’s really hard to drive straight. rm8, what’s your experience regarding this latency with your Double Trouble? If anyone has not seen rm8’s Double Trouble, I’ll put it as “my dream, properly done” Thank you for reading. If you were looking for a video... EDIT(25.05.2015): slightly better pics. EDIT(26.09.2015): I’m now a little more proud of my creation, at least the suspension seems right to me: it’s long travel and soft enough to reacts promptly to bumps, but the car doesn’t sink too much on it. I dare say it works better than most others, probably because it’s much harder to this the a bigger scale most others have been working with. The car is still not really fast, so I didn’t bother measuring its speed. I did try putting less reduction in the drivetrain, but that only resulted in lower speed due to lower torque, so I reverted back to my original setup. It’s still fast enough to be impossible to drive well, specially with the terrible latency in the SBrick. Latency is not a problem with the port tester, so it doesn’t look like a hardware limitation. Anyway, it’s fast enough to be fun. Thanks to Sir Wolf’s help and support, we finally have a somewhat decent video. Enjoy! :) And we learned many things the hard way: by failing. Fake caster angle is not good, you need real caster for off-road racing. I took the idea from someone’s supercar project here (sorry, couldn’t find it again) to displace the upper suspension arm by ½ stud backwards from the lower arm (see belly shot above). That gives you quite a bit of caster angle on the wheel (or snowmobile skies) but it does not help reacting promptly to the most serious bumps. It also screws the geometry in that the gear rack should ideally be ¼ stud backwards, but it’s either 0, ½ or 1. This results in notorious bump steering: front wheels are toes out when suspension is fully extended, and toes in when fully compressed. When this adds to the torsion exerted by the powerful motors on the live axle (see in the video how left front wheel jumps up when car starts). All in all: bad Idea. Portal hubs from 8070 are not good for off-road racing, I should have used the ones from the snowmobile 42021 (2015). They are also too expensive to go on dirt with them, so I didn’t. Differential slows down or even stops the car when one rear wheel take off. I knew this was a problem with crawlers, but never imagined how bad it’d be on a trophy truck. Damn it, I’ll never do this again. Just use one motor per wheel, and accept that if one motor runs out of battery or losses signal, you might take a sharp turn or find yourself driving in circles for a little, depending how the front wheels cope with the imbalance. MiniZip are great to get “buggy-motor-grade” power in a smaller size than LiPo batteries. PPA 9V batteries can fit a width of 3 studs, so a 5x11 panel makes for a perfect home. However, MiniZip’s lack of power switch in makes it a complete hassle to replace batteries. Should keep them very easily accessible.
  10. Hi everybody! Thats my new 4x4 rock crawler. So,here it is Specifications: -4 link suspension -portal axles -rc 108 mm tires -3s li-fe battrey -2 buggy motors -1 sbrick I hope you like it Let's see it in action!
  11. Quandary. First I apologize for the long post. I have finished the first stage of a large industrial MOC. So far it has 4 motors for several models AND 4 channels on an sbrick for an overhead crane. ( with more to come) I'd like some suggestions as to how to proceed with the animation/automation. I'd like to use a laptop as a central control point. I understand that sbrick is working with scratch on a pc interface. I have read that a pc running windows can communicate with an EV3 with Bluetooth protocol. Has anyone done any work with any kind of an integrated environment. Ideally I would like to make the EV3 sensor readings available to the pc and then issue commands to either EV3 motors or sbrick motors. The sensor capability of the sbrick is not versatile (at this time) to use a full range of EV3 sensors. Am I "beating a dead horse" with trying to keep the Ev3 + sbrick + pc in the loop or should I do a switch to Ardunio / Raspberry Pi / NanoPC etc? I 'was' an experienced programmer before retiring and am leaning towards a micro solution to get in a single language environment. Any help/comments would be appreciated. If you would rather continue this topic privately, drop me a message. Thanx
  12. Hello everyone! Since TLG released 76023, I had been waiting for affordable Technic set which includes so-called Tumbler Tires. So I jumped at 42050 Drag Racer. I also bought some extra tires separately, then revived old project which had failed three years ago. Avtoros Shaman 8x8 Building instructions: Rebrickable Weight: 2550g - 4x L motor for 8 wheel drive - 2x Servo motor for 8 wheel steering - M motor for switching steering mode (AWS and crab) - M motor for winch - 3x LED for front and rear lights - 2x SBrick powered by 2x 8878 rechargeable battery box - Independent suspension for all wheels - Working steering wheel - Openable hood, doors and roof hatch Back in 2013 As you may know, real Shaman is which can go through almost any kind of terrain. It has three steering modes and can scale 45-degree incline. On top of that it is amphibious. Seeing pictures and videos, I instantly fell in love with it.When I started the project, I was too ambitious to realize all features above. Sadly I could not build even steering mechanism while keeping all wheel drive and independent suspension. So I changed the project to building another 8x8 vehicle. It ended up as my Tatra 813 Trial Truck, but that is another story. Focus on characteristic features Two months ago, I suddenly came up with an idea that enables both normal AWS and crab steering. In the case of four-wheeler, you can do it by switching rotation of second Servo motor for rear axle. But in eight-wheeler like Shaman, you should change turning radius of second and third axle. In normal mode, the steering angle of inner two axles is smaller than outer axles. But in crab mode, all axles should be steered at the same angle. This is the basis of steering idea. I used the way of fixing/moving pivot of steering linkage. A: There are two 7L steering racks connected to 7L beams. Front rack is connected in the middle of beam, rear is one stud backwards. Both ends of beams are connected to steering arms of each axle. B: In normal mode, rear rack is fixed by 12T bevel gear. So the fixed pivot of 7L beam is its 5th pin hole. Which makes front end of beam moves twice as rear end does. That means the steering angle of 1st axle is twice as 2nd axle. C: In switching crab mode, 12T bevel gear moves one stud forward and fix front rack. Fixed pivot is 4th pin hole of beam. Which makes both ends of beams move equally. That means the steering angle of 1st axle is the same as 2nd axle. And there is one more twist. D: I put main steering rack (moved by pinion gear) on one stud forward of 7L beam's front-end (which means 9L beam’s front-end). Seeing from the pivot point, this rack is connected to farther than the point of front steering arms connected. So front steering arms always move slightly shorter than main rack does. When Servo fully turns 90 degrees, pinion gear moves the rack in one stud sideways. Steering arms move less than one stud. This was necessary for keeping CV joint (connected to steering hub) rotate smoothly even when fully steered. Challenge and compromise First of all, this MOC is NOT amphibious. It is too heavy to float. And because of driving motors of low position, chassis is not waterproof at all. So it is not recommended driving it through even shallow water pool. My aim was to achieve decent crawling capability. But I had to lower the bar because there was no room left for portal/planetary hub reduction. Without them, heavy load from 81mm tires directly goes to 12T half bevel gears. First attempt was using two XL motors geared 25:9. I put each motor for left/right side of axle. The result was unsatisfied. Even when climbing over small obstacles, bevel gears often slipped and got damaged. So I replaced them with four L motors geared 3:1. Each one drives a pair of half axles. Thanks to their good speed and smaller torque, new drivetrain proved to be more reliable. Although bevel gears were still slipping a bit, I accepted overall performance. The picture above shows two L motors for driving right side of axles. The power functions switch for changing rotation of rear Servo motor is synchronized with moving steering pivot mechanism. In crab mode, rear 4 wheels steer opposite the same direction as front wheels. As always I used few of non-Technic parts. Big roof tile was used for saving weight, curve slope parts were better choice for filling the gap. LBG axles sticking out the roof are visible indicator for steering mode. They are mechanically connected to switching mechanism. In the video you can see how they work. Instructions available at Rebrickable. Building it in red is possible by using red parts instead of white. I hope you will enjoy building!
  13. Updating the first post to have all three RC mods in one place. 1st version - Power Functions motors & SBrick control This is a quick and dirty upgrade, it started as a test to see if 2 or 4 L motors can drive the set properly, but things escalated quickly :) The aim was to add the PF components without taking apart the set completely or to change original structure, so obviously there are more elegant ways to hide all the motors and to upgrade the suspension and the drive train. The list of the added elements: 4 PF L motors (drive) 1 PF Servo motor (steering) 3 PF M motors (functions) 1 PF switch 2 8878 Battery boxes 4 PF lights 2 SBricks The 4 L motors can drive the car, but it has no extraordinary performance due to the added weight. The servo motor is struggling sometimes (especially when the car is not moving), it'd need another servo motor or some other solution for the steering to work smoothly. 2nd version - pickup-style body, 4 buggy motors, 2 BuWizz units After the first attempt I wanted to build something faster, so I had to reduce weight and add more power :) The back part of the truck was removed, I removed also a lot of non vital elements (like the fake V8). 4 Buggy motors were added and they were powered by 2 BuWizz units. The results was pretty fast considering the tracks and could handle the obstacles well. 3rd version - tracks removed, wheels added, pickup-style body, 4 buggy motors, 2 BuWizz units This is my third and last Lego 42069 Extreme Adventure remote control mod. After the previous version I did not plan to create another one but I was convinced by some comments on my YouTube channel (thanks for the tip!). Although I really liked 42069 on tracks, I realized that the top speed was limited by the construction so the 4 buggy motors could not show their full potential. I removed the tracks and added the wheels from the 9398 Crawler set. The pickup-style body was kept from the previous mod to ensure the car is as light as possible. The axles were rebuilt completely to fit the buggy motors and the wheels. The car is driven by 4 buggy motors and there's a PF Servo for steering. It is controlled and powered by 2 BuWizz units. It became surprisingly fast, I was curious so I added a small GPS tracker to measure the top speed - you can check the result in the video :)
  14. Hi to everybody! I'm here to present my new Moc. I started building this crane truck about 6 months ago with the main idea of solving the problems related to a failed attempt of a crane for my previous truck. IMG_1608 by Lucio Switch, su Flickr Starting from the cab...despite the undeniable resemblance to the cab of the dump truck (with a bit of the tractor truck), it has slightly different dimensions, and the add of some new details/functions, forced me to revise it completely. In fact, in addition to the "standard" opening doors, this time, as on real trucks, the cab is suspended, while maintaining the tilting function and the working steering wheel and the front grid is openable. Moreover the seats are pneumatically suspended via 2 (1+1) 1x5 pneumatic cylinders. The chassis has the tractions on the 2 last axles, they are driven by 4 XL Motors and uses 2 Servo Motors to steering the first two axles (with different turning radius). The first two axles use independent suspensions. In this case I was inspired by the Mod of the chassis of my Tractor Truck done by Efferman ... that has a perfect shape for a fake v8. On the back there are 2 live axles (with a total of 24 hard shock absorbers). Between the first two axles there are two small pneumatic pumps moved by two L Motors. In addition to that, on the chassis are present 2 Li-Po Battery, 5 Leds for lights and 2 SBricks. Behind the cabin there is the base of the crane, it contains the front stabilizers, extendable via a M motor (connected to one SBrick), 6 pneumatic valves, moved by an M motor each, 4 IR receivers to control the 6 valves motors plus 2 other M motors, one to rotate the crane and one for the winch. The 4 receivers take power from a port of an SBrick. Finally the crane ... well, the classic design of this type of crane with the upper arm offset (as on 8258 for instance) built on this scale, gave me big problems twisting the whole structure ... and a lot of headaches. One day I came across by chance in a truck with a Cormach crane, it presented a unique design that would solve the twist problem. So inspiring to this design, I have developed my crane, which consists of a telescopic upper arm (extension via 2x 1x11 pneumatic cylinders) supported by two side arms moved by 2+1 2x11 pneumatic cylinder each. It isn't able to lift heavy loads, but it works and, considering the masses involved, I'm fine with that. Now some numbers: Length: 86,4cm 108studs Width: 24,8cm 31studs, 28cm 35studs with mirrors Height: 39,2cm 49studs Weight: 8.6 kg Total number of parts: 8000 PF elements: M motor: 9 L Motor: 2 XL Motor: 4 Servo Motor: 2 PF LED: 5 Lipo Battery: 2 ..and a couple of wire extensions Pneumatic Elements: Small pumps: 2 1x5 Cylinder: 2 Medium Cylinder old: 4 Medium Cylinder new: 2 1x11 Cylinder: 2 2x11 Cylinder: 6 Valve: 6 ..and several meters of pipes. For more pictures check my Flickr Album: Crane Truck Flickr Album And this is the video: To conclude, I would say that, in some way it was a new and interesting experience for me. Due to circumstances beyond our control, I was forced to transfer my Lego room in the basement, comfortable although perhaps a bit rustic but not directly connected with my apartment. This, coupled with the fact that my free time has been drastically reduced, has led me to review my usual workflow. So this is my first model built before digitally and then physically. This way allowed me to use better my free time and to select and pick up only the needed parts to build, reducing drastically the mess in the living room. Also part of the work for the BI is already done, I'll done them for sure, but I don't have idea when they will be ready. I'm afraid that it will be a huge job! I hope you like it!
  15. I present to you my Lego Technic Chilli Crawler! This is a complete makeover and overall improvement from my previous Carrot Crawler: http://www.eurobrick...howtopic=112037 Yes, I know. This is the second crawler that I named after a vegetable; expect more! Features: - Triangulated 4-link live axle suspension using 4 soft, black shocks. - 4x4 with one PF XL motor mounted parallel* to each of the two axles. A final gear ratio of 1:5.001, yes this may seem slow, but the enormous Super Swamper tires make up for it. - Speaking of that, 4 RC4WD Super Swamper tires. No, they are not Lego, I got them from a nearby hobby shop. - One L-motor for steering in the front axle, geared down via worm gear to 8 tooth gear, then a 12 tooth gear to a 40 tooth gear. The 40 tooth gear drives another 12 tooth gear that moves a 13L gear rack. - Portal hubs for all four wheels. Standard Lego Unimog for the rear axle for rigidity; custom triangular plate portal hubs on front axle for a steering pivot point closer to the center of the tire. - Good articulation, about ~55-60 degrees. - Controlled with an SBrick. - Powered by a Lego rechargeable LiPo battery. - Green Chilli Stem** * The mounting of the drive motors parallel to the axles was a must for this crawler. By doing so, I have not only eliminated gear slippage as there are no perpendicular gears, but there is also a ton more ground clearance in both the front and rear axle. The rear axle especially as the motor is actually on TOP of the axle. Crazy, huh? ** Makes the crawler look so much cooler. Challenges: - As with all 4-link suspension setups, the mounting and placement of both the links and the shock absorbers proved to be a rather annoying, tedious part of the process. I have, however, managed to make a VERY rigid triangulated setup where the shocks are not bent or warped in any way. - The mounting of the two lower links on the front axle was also difficult as there was virtually nowhere I could mount these links onto. I was able to (somehow) securely mount both the lower links and the shocks of the front axle onto 7L and 9L beams on either side of the motor. - Mounting the motors parallel to the axles proved to be hard, but actually somewhat straightforward when it came to the rear axle. I had been so used to having drive axles perpendicular to the axle like on my previous crawler. The mounting of the front drive motor was difficult in the fact that its power is transmitted through various gears and the motor itself is connected to the axle by two plate beams and a pin or two. Although the front drive motor is still not completely rigid, I have had no problems with gear slippage whatsoever in either axle. Some pictures: And finally, here is the youtube video: I welcome any suggestions or comments you may have. I will, however, say in advance that I DO NOT plan on making a body for this crawler as I designed it for performance purposes mostly, a Lego "comp-crawler" as you may call it. Thanks, pt
  16. Hi Newbie around here, used to play with lego back in the days and somehow got back into it but this time as grown up and and adjusted gaming budget ended up buying some Lego Technics models along the way (mainly stuff with tracks :) ). So got my hands on the 42065 Tracked Racer, really liked it but fell in love with the B-Model/Off Road Truck and started putting my two RC 5292 motors into it. Here is a short video about the evolution to my so far "final" v5.3 Mod: Short recap about the progress: replacing the two PF motors with the RCs, and going for an SBrick increasing the wheel base and changing to 3:1 gearing, then getting to know about the fuse inside the battery box, adding suspension, moving the battery up increasing the wheelbase again to get two battery boxes inside and double the SBricks, and change to 1,667:1 gearing Putting the RCs horizontal with a 2.5:1 gearing Currently working on: Getting a GoPro attached Getting it a bit water/splash proof to be able to go through some puddles (so far cling foil wrapping battery cases) ToDo: Get some filminig done of the v5.3 with the 2.5:1 gearing Getting the PS3 controller working on the Nexus 5 together with the SBrick Future ideas Improving suspension, weight is currently heavy on the rear Getting a winch into it on the rear or front Automatic two gear box to get faster on plain surface and getting more torque when going through terrain, looking at sariels automatic two gear box so far, but it probadly wont fit p.s. These are my first attempts at shooting videos as well, so bear with me ;-) . Most of them are handheld from my Google Pixel while driving with my other hand on my old Nexus 5
  17. Hello Eurobricks, (sorry, posted by mistake , I'm currently writing the topic) That's OK now. If you get tired of airport vehicle, you can still escape. I had some time to kill during my forced holidays, so I present you my latest MOC, a baggage belt loader. This kind of vehicle are used to delicately load you baggage in the bulk cargo room of aircraft. The belt is made of two parallel tread sliding on studeless beam and are actuated by a PF-M motor + Worm gear (and some gear inside the conveyor). The U-shape prevent the tread to move. Regarding the other function, you can find steering (through PF-Servo motor), propulsion (through PF-M motor) and the elevation of the coveyor (through PF-M motor and linear actoator) Except the smal size of the model there is no real complexity in this MOC. I tried to add some small detail to make it look better, I'll let you discover them in the here below video. thank you for reading Complete album on Flickr : https://flic.kr/s/aHsm78fkMT
  18. How about that little cross between mud and go on the rocks? Crawler 4x4 always ready for it! Still would! Its wheels are shod with tires RC Rock Crusher X/T 1.9, coupled with portal axles and two motors running by SBrick and LiPo battery box - we have an off-roader with excellent maneuverability, suspension geometry and a low center of gravity due to the unsprung axles. Crawler 4x4 built under the rules of the forthcoming Off-road trial competition in Moscow, at the same time. I tried to build the chassis in such a way as to achieve maximum throughput and maximum flexibility - namely, so this chassis can set the wheels of virtually any size from 62 to 108 mm. The body of the model removable. This allows the chassis to this every body, even though the truck, even an SUV. Get more photos on my blog of flickr
  19. The only thing worse than a hungry meat-eating dinosaur on your tail is one with a tank! (Well, getting caught is pretty bad, too.) Battery: 7.4V PF LiPo rechargeable in place (was AA box) RC receiver/controller : SBrick/custom joystick on Android phone (was PF with bang-bang handset) Motors: L front and rear (were Ms) Drive train: Direct drive (no change) Steering: Differential power to the tracks (no change) Tracks: Lugs every link for traction (new) Overall dimensions: 206x170x146 mm (LxWxH) Mass: 546 g (down from 599 g) Installed power: 4.3 W (was 1.5) Power to mass ratio: 7.9 W/kg (was 2.5) Stalled torque: 0.52 N m (was 0.18) The biggest and most important advance over 42065 was in outdoor play value -- by far my best yet in any MOC or MOD. The biggest contributors there were the L motors and the red rubber track lugs. Dinotrack performance was generally traction-limited without the lugs.

  20. A few years ago I created a modification to the 42005 Monster Truck set, where I motorized it and made it RC (IR), but tried to keep the geometry as close to the original set as possible (see topic here). I always liked the design and size of the body of this truck, so I have used it again, but this time I have completely removed the chassis and the drivetrain, and inserted a new one. This truck uses: the Lego Power Functions Rechargeable Battery (8878) to power an SBrick which controls a 9V Buggy Motor (5292) for drive and a Power Functions Servo Motor (88004) for steering. The truck is controlled remotely using Bluetooth via the SBrick and SBrick Android App on my mobile phone. This truck features: large suspension travel Ackermann Steering and positive caster steering geometry. The tires (56908c03) are the tires that were first seen in the Batman Tumbler set (76023). Even though the wheels are so far apart the truck has a short wheelbase, and thanks to the Ackermann steering geometry and differential in the rear it has a fairly tight turning circle. The front suspension uses a single shock absorber (731c05) with a setup similar to the 8081 Extreme Cruiser set from 2011. The rear independent suspension uses two hard shock absorbers (731c04), one each side. Here's a video to see it in action: Although the Monster truck uses a Buggy Motor, I couldn't give it full power without the battery and/or SBrick cutting power to it. I could only go at about 70% of max speed. I didn't have much space for gear reduction (apart from a 20-tooth gear to 28-tooth differential), so the output doesn't have much torque when using such large tires. Because of this, the truck takes a while to get to full speed, and slows down when hitting an incline or going off-road, which kind of makes the large suspension travel a bit pointless. I might see if I can gear it down some time in the future. I still continue to have a lot of trouble with the SBrick too. I finally have a version of the SBrick Android App that seems to work ok, but despite being only a few feet away and with nothing else around to interfere with it, it would still lose connection with my SBrick regularly. Hopefully BuWizz will be better, and be able to power the Buggy Motor better too. My BrickShelf Gallery with larger images (once moderated) Any constructive feedback/comments/questions are welcome.
  21. Hi everyone, I’m please to introduce you my latest MOC, the Aircraft Super Tug, an attempt to make something inspired from the Goldhofer AST-1X 1360 used for moving biggest aircraft including A380 on airport platform. If you’re curious there’s some nice videos on Youtube. The MOC: [ All images are available on Flickr There is some basic function controlled through SBrick inside: Propulsion (1 PF XL) Steering (1 PF-M) through several mini linear actuator Catch the aircraft landing gear (1 PF-M): adaptable to different size of wheel Lift/down the aircraft (1 PF-M) through 2 linear actuators A video will explain better : There’s a lot of issues with the functions, the gears don’t engage properly so the truck is unable to move or turn under its own power. Not a great success so maybe I will restart this vehicle from zero one day to make a better version 2. Thank you for your time, best regards,
  22. IFS= Independent Front Suspension Hello all Today I'm proud to present my new MOC, the King of the Hammers IFS Buggy. This all started almost a year ago, when I wanted to build this, but changed my mind because of trouble with the rear suspension. So I made this in under a week, one reason for the speed of this build was that I used a pre-made rear suspension. It is a floating axle with four links designed by @Sariel, it works great on this model and gives it lots of travel. The reason I used this was because when I decided to build this, I thought that was what was used on the real ones. After closer inspection, I remembered this is just a live axle, with links going to a moving rod on the back. For example, this. So the suspension isn't realistic, but I think it works perfect on this model. For power, it uses a Minizip cable and 9V battery to power an SBrick, which controls 1 XL-motor geared 1.667:1 for rear wheel drive and a Servo motor for steering.

  23. Hi everybody! today i wont to show you my new creation - Gaz 34-6x6 soviet truck. This truck is modification of legendary Gaz 66.I'm crazy about 6x6 trucks,thats why I built Gaz 34. So,here it is: As you see,this is not original configuration of Gaz 34.I'm added portal axles(without diffs),bigger wheels and slightly changed the rear suspension.Finally-it is really good trial truck,with great grip on sand,grass (thanks to the wheels from 42054). So,lets look for the technical specifications: -6x6 wheel drive,without any diffs -portal axles -huge offroad wheels -2 buggy motors for drive -1 medium motor fot steering+micro motor(they tern steering wheel in the cabin) -Sbrick -3s li-fe battery(9,9 volts) -Leds lights(headlights) -balanced rear suspension(thats why truck has really good suspension travel) Let see it in action! https://youtu.be/hHDJLmvZ4BA
  24. Hello! We are ethusiastic adult LEGO fans and we have developed this new remote technology (kck.st/1sf6zOU). We know that lego is not just a toy, but an expression of the passion of creation. We are very interested in your opinion! Once upon a time there was a group of LEGO fans that had a dream, namely the dream of not simply taking readily existing building blocks to create a new model, but rather to create something that would take the LEGO experience to an entirely new level. They started their journey half a year ago but in order to fully realize their dream they now need your support. Take a look at what they’ve achieved so far and play your part to help turn what was simply a dream six months ago into a reality today . What they have produced is the SBrick, a universal remote control unit that slots simply into your existing LEGO models and allows you to control up to 64 Power Functions® units using your smartphone or tablet. This is just one of the very many things it does (there is a full list of the features listed below). If you browse any of the LEGO forums worldwide, it soon becomes clear that this is something that this is something fans have wanted for a very long time and the good news is that this very product is here now.
  25. hi everebody! Today i would like to show you my new 4x4 pickup truck. Specifications: dependent suspension portal axles 2 buggy motors for drive(geared 13,8 :1) 1 M motor for steering 107 mm wheels so,here it is and the video available here:
