  3. Hello everyone! This is my latest creation. ICARUS Supercar Introduction The name comes from a man who desired to fly higher using his technology. Many times I have tried to realize the speed what supercar MOC should perform. I needed “wing” called buggy motor, but all I had is a bunch of PF motors. So I connected motors together using “wax” called SBrick. Like Icarus of Greek myth, higher speed and torque may be lethal for the model itself... The result is here in the video! Weight: 1760g Propulsion: 4x PF L motor for rear wheel drive Steering: PF Servo motor Front and rear lights: 2x PF light Powered by: 2x SBrick and 2x 8878 rechargeable battery box Features: independent suspension for all wheels working steering wheel manually adjustable rear spoiler opening doors, hood, engine cover, glove box Drivetrain You may think it is not fast enough, but for me it was a relatively success. Surprisingly, gears and CV joints have never damaged or popped out even at the time of maximum acceleration. Although I had designed its drivetrain carefully, I was not sure if small bevel gears in differential withstand the load. Two 20T bevel gears of each side divide the load from differential equally. In this setting differential doesn't move back and forth easily. That means differential and 20T bevel gears hardly ever disengage. So they keep rotating smoothly even under high load. In this MOC there are three L motors (and two SBricks, two battery boxes, bunch of wiring) on the supposed location of V8 engine. So if someone build manual version with gearbox, there would be enough room for it. Body design As expected, building 1:10 scale supercar was very hard. Especially the body work. I've built one three years ago, but it was primitive MOC in every way. New MOC is heavily inspired by modern McLaren supercars. I tried to build their curved shapes using rather technic panels than flex axles. Front and rear light section happened to become different from the original mainly because of the positon of LED. Though finished model is not a copy of P1, I am happy with the result of realizing proper mid-engine proportion. Building instructions: http://rebrickable.c...icarus-supercar I hope you like it!
  4. Hey guys, so I made a custom SBrick profile for an upcoming MOC and I need to log into the SBrick app to use it. I haven't really used the app for about a year now, and since then I had switched to a new device (iPhone X from iPhone 7). Today I tried logging into the app, but when I put in my email and password a popup says "login failed". I then changed my password and was able to log in with it in the browser, but in the app it still says "login failed". When I hit "connect with Facebook" a popup tries to come up but disappears almost immediately. I also tried creating a new account with a different email, but even that says "registration failed". At this point I feel like it may be a problem with the app rather than my account, as I figure it would at least let me register. I emailed SBrick at info@sbrick.com about the issue but not sure if I'll get a response from them. I wasn't able to find much help online regarding this either. Any help is appreciated
  5. Hello everyone! Before I start I want to wish all of you to stay healthy, survive and win the disease! Today at my birthday I decided to share with you my latest MOC. This is a brand new Liebherr LR 11000. From the previous model, it took only some boom sections and proportions. The chassis and superstructure built from nothing and were rebuild several times. Below please let me share with you some dry specifications of the model: - Crane is about 2 meter high - weights 5 kg - requires at least 5 big battery boxes for been fully operated - can be managed by 3 sBrick units. - has 10 PF motors (4 are in the chassis) - Has 9 pneumatic cylinders + a pump - Has a full-size V6 diesel fake engine like the real crane - Has 6 winches, 3 of them are installed to the boom like in the real crane, but none of the motors are on the booms. - Crane is able to assemble and disassemble back from horizontal to working condition without any human help. - Has 4 pneumatic features, three of them are operated from the cabin, two of them are operated from the operators work seat Now is hte time for it's features: - Driving and steering - one XL motor per each track. Torgue increased 1:25 - Slewing by 2 M motors - L Motor for SA Frame winch - L Motor for the Main boom winch - M motor for the luffing jib winch - M motor for the secondary hook winch - L motor for the main hook winches - Pneumatically adjustable operators cabin - Pneumatically adjustable derrick counterweight horizontally - Pneumatically adjustable derrick counterweight vertically - Pneumatically rising chassis for (dis)assemble. - L motor for the pump and V6 engine - Individual Sbrick custom profile - 3 Pair of lights: - Front LED - Cab LED - Main hook winches LED Here is the link to photos, I'll post some directly here: https://bricksafe.com/pages/Aleh/2020-lego-liebher-lr-11000 Bonus: Here is the performance of the superstructure stability without boom and without counterweight(!), only one battery box insalled for fotors activity. Boxes are full with batteries (24 pcs) Easy to fix the front suspension: https://bricksafe.com/files/Aleh/2020-lego-liebher-lr-11000/IMG_2983.jpeg/800x600.jpg 1,5 kg load. Please enjoy and feel free to ask any questions.
  6. Hi everyone, Finally, I have finished a project which I was building since last September. It is the scale model of the Intrac 2011 snow blower which is/was often used in the swiss alps by the army and other communal parties. It was the aim to create another working snow blower after the success of the snow blower from last winter. The blower is powered by three buggy-motors which are all controlled by a separate Sbrick. Each track is driven by two PF XL motors. The snow blower shoot direction is controlled by two 9-volt micro motors and the height of the snow blower by one PF L motor. As power source I used two Buwizz as battery or a custom lipo battery. After a certain time in the cold I had the replace the Buwizz with the custom lipo battery. Cheers FT
  7. Hi there, I've developed a very annoying habit in the last few years. I randomly build pickups and other 4x4's. Even bought a real one. Anyway, the latest one is quite a biggy (sizewise) thanks to the planetary hubs. I've found a trick build them into solid axles with a practical ground clearance. This trick is going to be conroversial here. But start up with the video instead: All pics to be found here: https://bricksafe.com/pages/Attika77/ultimate-pickup In the comments under the video, noble members of our community noted, that there are parts which could solve the 1/4 stud misery. (if you don't know what is that, off you go, and whatch the video to the end! ) One of these is the 14t gear from the old diffs: I've made the attempt, but due to that collar on the bottom (top on the pic) it is too wide and puts srain on the drivline, making it hard to turn it by hand, so it is off the table unfortunatelly. So I speak for myself when I say, cuting those axles worth it. Not a rare piece, and costs 1 cent on bricklink, but only because there is no smaller value in the currency itself. In return the design prooved itself very reliable. Another "weakness" of the axle is the inperfect geometry. The wheelhubs aren't completelly vertical. There is about 1 degree tilting inside on the top. /---\ Before overdramatising this atribute, think, if you've noticed it in the video? Apart from the axles, the rest of the truck is the product of those years I've mentioned above. The essence of it is a simplest possible drivetrain: And a steering solution refined for non-rack steering: (The render is made of an older version, hence the different connector) If you don't belive your eyes, yes I choose to use 4x2 beams to form steering arms. It looks savage, but it is doing the job very well, brings ackerman geometry in the game. It does not hold the wheels rock solid of course, but in practicality it isn't noticable on the field. I've got a rack steering solution as well, but that brings the servo down A, onto the front axle (I don't do that. Ever ) B, into the mid chassis, where I don't have room for that. So we keep that for another build. Also has a working steering wheel using the rear output from the servo. ame old bevel system I've been using in most of my builds. Check the 1st episode of the pickup saga for more on that. Suspension Solid axles on a 3 link setup. It is kinda made up design, slightly inspired by the rear suspension of my Isuzu Trooper. Changing the shocks, or their hinge point on the top, gives 3 different ride height and suspension stiffness. The black, soft springs give a softer, relaxed, lower stance to it, while the dark grey shocks (known from the set 8880) are lifting the truck to a practical maximum, but still can reach full articulation. Not in all situations good to have your truck up in the sky. Like the climbing in the video. With low shock setting it made 52 degrees, but 47 "only" on big wheels and lifted shocks. The center of gravity moves with your ground clearance. That's about it, the rest is smoke-screen, like the body, and fancy doors. Oh, here is a fun fact: When it came to the seats, I realised I have 2 adjustable seats salvaged from a lorry build from about 5 years ago. Luckily they fit perfect so just made a rear bench in the same style. A non adjustable lazy style. Please feel free to ask about it, or just say something about cutting axles. I hope you find something useful here to take home with you.

    [Moc] The Lego Fire Station

    Hi everyone. I show you my project of a fire brigade barracks. The first three renderings date back to March 2016. It took me a few months to recover all the necessary pieces. Over time there have been several changes, including the addition of a courtyard with several other small buildings and a maneuvering castle (the building that use firemen to practice). The original idea was to replicate an existing barracks located near where I live, in fact, soon the project was transformed into something certainly simpler trying to bring together in the same building an office area and a car storage area. Currently I'm working (through stud.io 2) to version 3.0 of the barracks, you see the first renderings in the last two photos in this topic. Version 2.0 was made with the use of a Sbrick, I leave videos demonstrating how it works. And next next step... Fire Station 4.0 powered up by PFX Brick.

    RC Car Toy Story

    Hi everyone, Here is my last original creation : The RC Car from Toy story movie ! I would like to make a RC car controlled by smartphone and easily recognizable by young people (and older one too...) Features : RWD by 2 L motors Steering by 1 Servo motor Controlled by 1 Sbrick (or 1 Buwizz without bbox) Independent suspensions External switch for power supply Some nice colors I used 2 pythagoriciens triplets to improve chasis stiffness. The car is divided in 3 modules : front, motors and rear In the picture below you can see red bush on 4l axle with stop. It's the switch to power up or down the battery box. I used Anto's buggy motorisation : http:// http://www.techlug.fr/Forum/viewtopic.php?f=5&t=11544 but il replaced 8t by 24t. HD photos gallery : https://www.flickr.com/photos/147164115@N07/albums/72157713497548457 Building instructions are available : https://rebrickable.com/mocs/MOC-39835 I added 3x3 lime dish for the eyes on 3D model : I hope you'll like it, See you soon !
  10. Hello! This is my new Moc: a Scania S730 tractor unit, in 1:17 scale. It was built during free time between march and october. It is full RC with an XL motor for driving, and Servo for steering, and a Sbrick to remote control. It has opening doors and detailed interior. On the rear axle there are pneumatic suspensions, controlled with a manual pump at the back of the cab. The model has a "showtruck" look when suspensions are raised: Stickers are self made, printed with different shades of white ink on black vynil. Tyre badges are directly printed. The most challenging part of the model was to create the steps to access the cabin... and the cabin itself! It is 18 studs wide (cab and front bumper), but the roof, on the front, is 17 studs. The wheelarches and sideskirts are 19 studs wide. The cab can be romoved, to access to the battery box. I'm considering put this model on Lego Ideas. I'm not able to make instructions so if somebody would like to build it, they must vote for it! (just joking ) A trailer is also under costruction!

  12. 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.

    SBrick General Discussion

    Hi everybody I had the opportunity to test the beta version of the new Sbrick app, which will be released in one or two months. The new app is convincing. It is perfect for MOCs with special demands. However, to set up a program is more complicated as with the present Sbrick Profile Designer. Nevertheless, there are now a lot more options to create custom functions for your models. Some of the new features of the app: It is possible to create loops Queries from the Sbrick can be made Sounds from the mobile device can be connected to slider positions It should also be possible to control functions with a gamepad (I haven’t tested it until now) mathematical operations can be used in the app I tested the app with my MACK Anthem MOD. With the new app it is possible to automate several functions of the model: [media] Cheers Simon
  14. This year I spent less time online due to several reasons (like my career) but I haven’t been hanging around when it comes to LEGO. Next to co-organize LW I built a couple of models and one of them is this Scania T143 bulk hauler. I originally started with mk1 in 2016 but gave it an overhaul in 2017. For sure it is based on Ingmar Spijkhoven’s model but actually I wanted to give it a personnal touch. Is has another chassis and drive train which is more based on Jaaptechnic’s Actros. The cab is different from Ingmar’s. I chose for the original side panels with the typical 2-series and 3-series shapes. The rear panel got the same treatment. The truck is powered by a singe XL motor with is strong enough to pull a drawbar trailer. Both bodyworks can tip with a XL motor and it has lights on front and rear. It is supplied with an SBrick. Special thanks to Dirk Klijn and Jaaptechnic for the high quality decals. For more pictures please have a look in my album: https://flic.kr/s/aHskrBEUtv
  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. Hello everyone. As a monster truck MOC was one of my earliest creations, the time has come to remake it! Weight: 2030g - Powered by 2 SBricks - 4 XL motors for propulsion - 2 Servo motor for steering - M motor for switching steering mode (normal/crab) - M motor for raising front hood and rear bed - LED lights for headlights - Openable doors and tailgate Those old-school power functions components still work sufficiently in this MOC. The body was inspired by 80's monster trucks made from lifted and modified Ford pickup trucks. The under structure was designed for robustness. Eventually it looks more like modern tubular chassis. There could be multiple options for the sets of dual shocks. (Hard/Soft, Hard only, H/H, S/S) Vertically placed M motor moves Polarity Switch connected to rear Servo motor. Horizontally placed M motor is for two functions. Front hood opens via worm and 24T gear. On the other hand rear bed is raised via small actuator. That requires two driven axles of different torque and rotational speed for each side. Center differential enables single motor to transmit the power to both sides. One of the benefits of portal hub is easy to change gear ratio. Body parts could be replaced with different color scheme, though they are not fully modular. On November 2nd and 3rd, Monster Jam live was held in Japan for the second time. I did go to the event and took photos of amazing real monster trucks and drivers. Thank you, Bari Musawwir and Neil Elliott! Building instructions available at Rebrickable.
  17. Hello everyone. This is my second Tatra model.Comparing to previous Tatra 813 Trial Truck built in 2014, it is bigger, heavier and a little bit faster. Weight: 3810g Length: 62.4cm Width: 24cm Height: 25cm -Powered by 2 SBricks -6 L motors for propulsion -2 M motors for steering -M motor for 2 speed gearbox -Working steering wheel and V12 engine -Openable doors, front grill and roof hatch The model was specifically inspired by a unique truck of Jansa Team participating at real truck trial events. I tried to replicate overall look as possible without using any stickers. The cabin became one stud longer than it should be. Also using many system parts was somewhat compromising as a Technic builder. This time I omitted offset axles because symmetrical structure was more robust and efficient. Each side of half axles are independently driven via two parallel drive shafts. That enables slightly smoother turning than previous one adopted single drive shaft. Body parts are removable by pulling out both seats and two 5.5L axles behind the rear bed. When I completed the chassis early in 2018, it never came to my mind that LEGO would officially release "game changing" planetary wheel hub. Admittedly those bulky half axles using portal hub look outdated in 2019. The core of chassis contains bunch of L motors which I called 'Six Pack Abs'. The gearbox is simple yet packed 16 gears into tiny space between L motors. Although suspension mechanism is not like real Tatra, pairs of swing half axles move like real one. That realizes good off-road capability. The steering angle of 1st axle is twice as 2nd axle. Two hard-coupled M motors move 13L gear rack via dual pinion gears. For more powerful steering, I did not use white clutch gears. Consequently geared down motors keep rotating and make clicking noise when gear rack reaches end position. After all, this MOC ended up to be just a big truck driven by old technology. (Strangely it sounds like aged Tatra 813 in modern truck trial events...) Still I am happy with the result and sharing another massive 8x8 model. If you like it, feel free to put colorful stickers on it, make alternate cabin design or build more accurate chassis with new hub parts. Building instructions available on Rebrickable.
  18. Hello everyone! Thanks to the purple Titanian, it took 18 months for coming back from yet another dark age in my life. Now I am here with yet another pickup truck. Design was inspired by Ford Raptor, Dodge Ram and GMC Sierra. Dacoma 4x4 Redux Weight: 1360g -Powered by Sbrick -2 L motors for propulsion -Servo motor for steering -M motor for two speed gearbox, (sort of) limited-slip center differential and lockable rear differential -LED for headlights -Openable hood,doors and tailgate Video: https://www.youtube.com/watch?v=qMUH1YmF1F4&t=1s This is an improved version of my Dacoma pickup truck and TLC 80. I could not finish building instructions for them because they had fatal drawbacks on their drivetrain. In low gear, bevel gears in center differential often skip and pop out by the torque of propulsion motors. To make it reliable, it was necessary to reduce the stress on center diff while handling higher torque in low gear. The gearbox works sequentially. (1 - 2 - 3 - 2 - 1) 1: High - 2: Low - 3: Low with rear diff lock In low gear, center diff works like limited-slip diff. In high gear, two L motors are coupled and rotate center differential together. Front and rear axles are driven via open center diff. In low gear, only one L motor rotates center diff. Another motor is connected only to rear axle. (In other words, it just supports rear half of drivetrain.) Which means rear half of axle in center diff is (nearly) locked. That means front half of axle in center diff is locked as well. Maximum suspension travel is not as long as older Dacoma truck. But new one articulates better thanks to softer front suspension. Years ago I happened to get some rare blue parts from old sets. So I could build it in blue. With a few tweaks, it can be built in white, orange or black. Building instructions: https://rebrickable.com/mocs/MOC-25520/Madoca1977/dacoma-4x4-redux/#comments I hope you will like it. And I will work hard not to take a long time for sharing next model.
  19. The Volvo FMX is an oddly styled truck, its bulldog nose like design stood out to me instantly. Having an inherent weakness for the odd I decided to build one all the way back in 2015. Four years later I proudly present my latest model :). Developing the Palfinger crane took the better half of the development time for this model. In order to house all the electronics necessary a flatbed truck design was chosen with 4 axles, 2 under the bed and 2 to support the crane and cabin. The crane is operated by 3 servo-controlled pneumatic switches, the newer style switch allowed me to build this more compact than we ever could! The Pneumatic cylinders for the extension sections have been modified to allow for a more realistic reach. Two original cylinders were cut and acetone welded together for each one of them. The compressor is powered by an L motor and assisted by a rubber band to reach the pressures necessary to operate the crane. The crane is able to reach the back of the bed, as was my goal, but isn't able to lift much anymore then, the limit of pneumatic control is really stretched when a single-cylinder needs to push an arm of 30+cm on a point 5 studs away from the pivot point. With all this functionality, details are fun but also frustrating to add. Two tiny tool compartments have been fitted on the rear of the truck stowing away lifting equipment. The engine is only built for the upper 2/3 to accommodate for the suspended axles and steering mechanisms. The model is also fitted with a full custom led kit. A custom electronics board with an Arduino pro mini takes the signals from the Sbricks and converts them into turn signals, driving lights, hazard lights and much much more. More can be seen on the Flickr album and in the Youtube video!
  20. Hi all, Recently I wanted to try to modify the 42037 Formula Off-Roader with the SBrick remote control and Power Functions. It is done with two L-motors for rear-wheel drive and the servo for steering. It is little bit larger modification but the shape is still close to original. Only the back of the buggy is bigger to accommodate the large battery box. It is capable of riding in a short grass and even climbing to a moderate hill. The final gear ratio is 1:2.334 but can be easily changed for higher speed on a smooth surface. If you are interested, here is the LDraw file: 42037_-_formula_off_roader_sbrick.mpd (original by Philo). PS: On the photo are different front springs as the front is very light and I wanted softer suspension.

    Multi-Train Control

    We’ve been working on redesigning and improving our web interface to control multiple trains using one tablet / phone. Besides the trains, you can of course also control all the other devices in your layout: switches, lights, boom barriers, etc. We added the following features: Support for SBrick We have added support for SBrick controllers, so now you can control LEGO PU hubs, SBrick and our 4DBrix WiFi controllers with our system. Just like for PU hubs, controller SBrick requires a BLE112 dongle and an software license. Touch Controls You can now control the speed of the train by sweeping the power control, see video below. It’s a very intuitive and effective way to control the trains, especially to position them. Skins We have redesigned the multi-train interface. It now uses skins so you can customize the look of the app in function of the train you’re controlling. We’ve tried to give it a LEGO feel. At the moment you can use a number of pre-defined skins. The goal is to support custom skins in the future. Emergency button We also added an emergency button so you can immediately stop all trains in case that’s needed. You can see it at the bottom of the screen capture of the control app. Let us know what you think and don’t hesitate to get in touch with us if you’re interested in controlling your LEGO train layout this way. ---- P.S. the initial post had an incorrect link to the YouTube video, this has been fixed now.
  22. How to create your own controller for SBrick (Profile Designer) First Run of your new SBrick
  23. "proof of concept" using one raspberry pi to control two LEGO trains: The trains are detected by reed switches. The Raspberry PI sends commands over bluetooth to the SBricks mounted on each train. The code on the raspberry PI is based on this code: https://github.com/J...ick-Stress-Test by GitHub user JorgePe. He also has details on the implementation in the SBrick wiki: https://social.sbric...client-scripts. The only cable-connections are from the raspberry PI to the USB power supply (white box) and to the reed switches. Even at this early stage, this can be helpful on small train layout at exhibitions by adding some random elements in the timing.
  24. Greetings! After coming out of my Dark Ages and tackling both the excellent Ultimate 8043 & 42009 (see below) designed by Jurgen Krooshoop, I was hungry for another Lego Technic challenge. But I felt rather lost at this point: without a large collection of loose Technic pieces at my beck and call, motorized MOCs which weren't heavily based on existing Lego sets would require some hefty Bricklink investments from my part. Fortunately, a fifteen-percent-off-everything anniversary sale at a local toy store with an expansive Lego section made the choice for my next project a lot simpler: they had the 42043 Arocs set that had already been calling out to my wallet since way back in oh-fifteen. They also had a certain little gizmo called an SBrick in stock, which I had heard quite a few things about. My previous builds had involved standard PF receivers and remotes, so it seemed like an interesting new challenge to incorporate this new-fangled blue-toothed thing-a-ma-jig into my already-slightly-more-challenging attempt at "RC-afying" the Mercedes. I'm already a little way into the project, but I've already made a few false starts and moronic missteps, so I figured it might be educational for others to document my frantic flailing about experiences, so that they might avoid my (myriad) mistakes. The first thing I did, of course, was to order the necessary PF components: a Servo Motor, an L-Motor, an 20cm extension cable, and a couple of PF lights. In hindsight, this already turned out to be my first mistake: I hadn't done my research properly and hadn't realized that the SBrick requires an extension cable to be hooked up to a battery box. This meant I was probably going to be one cable short, since I didn't think the cable for the L-motor used for drive would reach. While I waited for these crucial parts to be delivered, I began preliminary work on the Arocs proper. After completing most of bags 1 to 3, I had three loosely connected main sections of the truck - the cabin housing the 6-cilinder engine and the L-motor that came with the set, the gearbox with the outriggers, and the rear section with the dumping bed and the differentials. In my mind, I could already see a problem arising: there was a drivetrain going from the rear wheels all the way to the engine in the front of the truck, which would obviously make the pistons move as you move the truck along. I already guessed I would be severing this connection by remove the driveshaft with the CV joint and attaching an L-motor in the center somewhere. Which would render the engine, the drivetrain, etc. utterly useless. This was not acceptable - not in the last place because my kids had unanimously decided that seeing the pistons in my 42009 mobile crane move was officially The Coolest Thing Ever™. So I fiddled about a bit before connection these three main sections, and eventually came up with this: Might be a bit hard to see, but... Basically, I placed an additional small gear directly in-between the L-motor and the gearbox, which allows it to power the axles and gears connected to the piston engine when in use. So, it wouldn't be connected to the drive anymore, but at least there could be some motorized eye-candy when one swung back the cabin and fired up the main engine. It wasn't long before my motors and such arrived, so the first I tried to accomplish was to connect the L-motor for the drive somewhere. One nifty solution I'd found involved replacing the engine in the front and using the long drive-train to power the rear wheels -- a technique I thoroughly rejected for several reasons: It seemed inefficient, and COOLEST. THING. EVER. So I figured I'd just bolt the bloody thing directly to the rear diff, as I'd also seen in this fascinating and classically scored tutorial vid by RC-master PPUNG daddy: It didn't sit right with me to just attach the motor with two pins like that though, so I have attempted to support it a little bit better without messing up the way the rear suspension works too much. Right now, it looks something like this: Not exactly perfect, but it seems to work well enough, even when I give the suspension a bit of a work-out. Next came the steering. My first attempt was based on this extremely helpful Youtube video by yu shine: Basically, this involved just connecting the Servo directly to the standard HOG steering mechanism for the Arocs, just below the two orange lights-slash-knobs at the top which you're supposed to turn. It seemed the most simple and elegant and -- being but a simple soul -- this naturally appealed to me greatly. It also didn't require the purchase of any additional parts, and left the mechanically unique way the steering on the Arocs model works intact. At this point I was able to put together a sort of prototype for the RC driving, by dangling the SBrick from the battery box and just hooking everything up in a makeshift manner. After installing the app, setting up the official 42043S profile, and playing around with my handiwork for a bit, I discovered the following issues: The L-motor was supplying quite a bit of power, making the truck actually pretty hard to control. Of course, there was a lot of weight left to be added at this point, so I was willing to reserve judgement for the time being, but given that my kids no doubt want to play around with this thing as well it'd be nice if I could prevent them from semi-accidentally ramming a massive Lego vehicle into, well, practically everything. Not sure how I could address though, other than from the software side. Placing the Servo motor where it was, behind the battery box, didn't actually fit all that well. The battery box itself actually pushed up against the servo when inserted, bending it back by at least a stud, which also frustrated my attempts to secure it in place a bit further. The steering was a bit... inadequate. The problems regarding the steering I recalled Sariel already mentioning in were only exacerbated here. It felt imprecise and rather unresponsive, and it didn't help that there was quite a bit of play in the wheels even with the Servo hooked up, meaning they weren't necessarily centered even when it was. So in the end, I stripped the away the steering mechanism and the wheels up front until I was left with this: After that, I decided to pony up and order the parts which -- after careful visual inspection of PPung's tutorial -- I figured I'd still need to mount the servo at the bottom, between the two sets of front wheels. So, mostly a set of gear racks and gears, in addition to some beams and various connectors used for bracing. This also gave me the chance to simultaneously order an extra extension cable from the same supplier, since it was pretty clear I was going to be needing it if I wanted to have any hope of hooking up the drive motor to the SBrick up front. And now, we wait... Although, to pass the time, I busied myself with rebuilding the back of the cabin, which I had previously taken apart to place the servo motor. I didn't need all the gears used for the steering mechanism, of course, and I figured I'd be better off trying to mount the SBrick in this space instead. For the moment, I came up with the following: I did notice the two black Technic pins still sticking out back there, and peeking ahead in the manual revealed that these will be used to help brace the pneumatic crane, once the time comes to attach that beast. As far as I can tell, that should still be possible even with the SBrick where it is, but no doubt I'll have screwed up somehow. We'll find out in the next update, hopefully! (Assuming, quite optimistically, that there is actual interest in such a thing. )
  25. Hey Eurobricks, PunktacoNYC back again with another rock crawler! This time it's called the Rocket Crawler and it is my largest, fastest crawler yet. Youtube video: Features: - 4 L-Motors for drive (one per wheel) - Ackerman steering with custom virtual pivot system to maximize steering angle - Rigid, triangulated 4-link suspension with 100% Lego-legal original, extra large links - Very minimal, light bodywork, and a cute rocket atop the cab - BuWizz for extra power and SBrick for a great custom control scheme - RC4WD 2.2” Bully Competition Tires The initial inspiration for this crawler was twofold; I wanted to build a RC competition super-class-like crawler, what with giant relative wheel size, slim body, and high articulation. I also really wanted to make use of RC4WD's quite large Bully competition tires. This project has been in development for over a year thanks primarily to issues with the front axle. The problem with the front axle was that Lego universal joints simply could not handle the high torque required to spin such large tires. I tried using custom Lego universal joints custom dremeled brass remote-controlled boat u-joints, and even knob gears at the pivot point - nothing worked. So, I mounted the motors directly to the wheels, all within a virtual system to move the steering pivot closer to the center of the wheel for a better turning radius. There is approximately 90° of articulation between the front and rear axles: Easily adjustable suspension height: (high) (medium) (low) The chassis: Wheel comparison: Concept 1: Concept 2 (later): This has been my favorite project. Let me know what you think. P.s. I got a snupps page (nice idea, Sariel): https://www.snupps.com/punktaconyc
