  1. I made this last year and didn't get around to make a topic about it until now. A video of it transforming: The model weighs 1.6kg and most of that is on the front axle. I haven't been able yet to make a mechanism that will allow Optimus to lift himself without a "hand of god" Some more photo's The rope you see between the front wheels in the photo above is what makes the flaps with the headlights at the front besides the grill fold back when Optimus is standing, but flex (thanks to rubberbands) when the hands need to be folded back into the body when he's transforming into a truck. The little grey wheels you see at the rear wheels make the black rear wheels barely touch the ground, this helps the leg spread mechanism. Speaking of which, the clicking in the video comes from these 2 mini-LA's in the legs: They make Optimus spread his legs a little when he's standing. I thought that looks better than him simply having his legs straight when standing, but the gearratio is off. If I manage to make a mechanism for the legs that works in lifting the model on its own then I might be able to tackle this gearratio too. In case somebody wonders where I put the battery box, it's external Thanks for taking the time to read my topic, hope you enjoyed it. If you have any questions, feel free to ask.
  2. After several years I am back! My latest MOC is Lego telehandler based on CAT TL642. Since it is not an exact reproduction I decided to change name and logos. Buwizz and iPad are used to control it remotely. There are four motorized functions: drive with PF L motor, boom elevation with PF L motor, fork tilt with M motor, and steering with PF servo. Front wheels are driven through a differential, and the rear axle has a simple suspension. Overall, it is maneuverable, easy to operate thanks to the proportional control of Buwizz, and very fun to play with. Please check out my flickr and https://www.flickr.com/photos/marat_andreev/ my instagram www.instagram.com/legomarat/ Interior controls are made with stickers Also I found a nice reflective sticky paper to make mirrors
  3. As soon as I saw the new parts in the 42159, I knew I just have to use them to upgrade the previous version of the Universal 4x4 off-roader. After tinkering for a few weeks in LDD, and actually building it IRL yesterday, it is officially finished: The V2 has a big list of upgrades comapred to V1. Dual independent drive, one for left and other for right wheels - allowing skid steering Two 3 speed gearboxes - that's right, this is my first off road vehicle with 3 gears for optimal performance Improved steering system - much more direct, accurate and responsive Highly modular design - easier access for maintenance and charging Top speed has been increased by 40% both in low and high gear - the previous version had ample torque, so I geared up all the ratios by 40% and added a middle gear Increased suspension travel at the rear - first time I'm using 11 studs long suspension arms Improved drive motor mounting - now they are no longer at a weird angle Similar part count to the V1 - even though it's 2 studs longer and has way more functionality it has only 20 or so extra parts, totalling at 796 (I tried to keep it under 800) Here you can see how the model looks in LDD: Overview of drive, switching and steering drivelines: The dual driveline is powered by 4 BuWizz motors, 2 motors for each side. The lower PU L motor moves the steering rack via an 8 tooth gear. A second, higher mounted PU L motor spins 4 wave selectors via 8 and 28 tooth gears which in turn switch between the 3 gears. The gearboxes have the following gear ratios: First gear is 20/16 = 1,25 - totalling 4,32:1 gear ratio from motors to the wheels Second gear is 24/12 = 2 - totalling 2,7:1 gear ratio from motors to the wheels Third gear is 28/8 = 3,5 - totalling a 1,37:1 gear ratio from motors to the wheels Thanks to the 3 speeds gearboxes, the model has plenty of torque to climb at 45°+ degrees angle, yet can also reach a speed of over 18 km/h, making it my fastest dedicated off-roader to date: Testing it outside, jumping over pump track course, driving through tall grass, etc... I have yet to encounter any major issues. The model is reliable, fast and can take a beating/rollover with ease. So far I'm really happy with it and can't wait to record more media and publish it soon, so stay tuned!
  4. Hello guys, Do you like oldschool Lego Technic with a single motor and many functions? I hope you would like my excavator. It has only a single PF L motor and is fully functional. It can drive and dig. Enjoy the show 😀
  5. Just began another baja/ trophy-truck project, the other 2 (or 3) being ”canceled”. I managed to put 2x L motors and 1x servo motor, both Power Functions; it also has positive caster-angle, independent suspension in front and solid axle suspension on the rear, (at least) semi-detachable body and the headlights can be be lit (there are 4 pin-holes for installing lights). Heavily modified version of this
  6. Wasn`t sure if i had to post this on the old thread or to make a new one, but I decided to be safe. Anyway, I recreated Jantayg`s buggy made for the BuWizz 2018 ”Fast car competition”, but, being a recreation not a copy, differs in some manners, such as the way the front frame is attached to the main chassis. This MOC has 1x buggy motor and 1x servo-motor, pneumatic shock absorbers, a good suspension travel and a space more than enough for the battery/ electronics but sticks to around 700g with 1x battery. You can find the digital construction file and the part lists for the other paint-jobs on Rebrickable Thanks to the original creator that accepted this recreation to be made public!

    [MOC] Pirate Death Star

    Ahoi and may the force be with you, pirate! Finally I present to you the MOC by my friend Jan-Hendrik and me: The Pirate Death Star some may have seen it in person in Skaerbaek last autumn but now I had time to post it... The different Death Stars are a building project invented by my LUG Steinhanse, so every year there will be several crazy Death Stars! Video Levels The death star consists of 4 levels and a big cannon, as the original lego set. The levels are devided as follows: Level 0: Deep Sea with fish and all the different sea creatures The Kraken Atlantis and more Level 1: Caves and shipwreck: The caves of the islanders, full of treasures. The pirates tavern under the hideout, partly in the old shipwreck. The dungeon of the redcoats The shipwreck Level 2: Island: The beach of the islanders The pirates hideout The Shipwreck bay The redcoats fort Level 3: Battle at sea : Ironhook and his Renegade Runner Revamp fighting Governor Broadside. Captain Redbeards crew on a treasure hunt, as well firing the big cannon. The redcoats lighthouse. The story of the plug. The caves have accessible stairways to the island. At sea level a technic chain powerd by a motor moves the boats and fish around. The big cannon fires a "Death Star cannon ball" All around in pictures: Level 0: Level 1: Level 2: Level 3: So, I hope there are not to much not not to few pictures.... I am really looking forward to your comments and hopefully some of you have seen it in Skaerbaek! All the best! Adrian
  8. I again wanted to go big on this build. Like BIG. So I went 1:16 scale the best I could. I started with an existing design from a failed build. The plan is to have 2 PF-L motors for the drive, PF-XL for the boom, and PF-M for the rest. Please note that I'm almost done with the build, but I am making minor adjustments to the build to help with function and/or weight support. I will be posting here to "show my work" of sorts and get feedback. I have been busy catching up on other things and building the excavator. (not much free time for posting/commenting on here) This was the first version of the bottom: And the start of the upper: It was looking good, sort of, I had to redo all of it as I add the battery boxes and arms it had a weak structure and was "clunky" in functions. I have remade all of the above and will post more in the morning to not have too many pics in a single post.
  9. Hello Train Tech! I haven’t been here for a while, but I have been building trains! I recently came across an old thread on the Boston and Albany 4-6-6T suburban tank engine, and I saw a comment about its smaller sibling. Well, I am here to share not one, but two suburban tank engines, including the aforementioned 2-6-6T, which I still consider one of my best models to date. To make things as confusing as possible, the NYC called both of these engines D-2a, though not at the same time. The 1912 D-2a (2-4-4T) went out of service shortly before the 1928 D-2a (2-6-6T) changed names. Both engines can navigate all R40 geometry and are much more buildable and usable than my first suburban tank attempt, though the 2-4-4T has to use Powered Up due to size limitations. The two videos at the end go into more detail about each engine and build.
  10. Hello, folks! Without long introduction - here are all my brickheadz so far (more than half are new, others - you could see them, but they have been slightly reworked). Note for mobile users - there will be many pics to load for your device. All building instructions are free. I'll add some comments by the way, but pics should do better :) 1) Newlyweds - kinetic model Animation (it may take some time to load): What is love? Baby don't h.. Hm, that's not what should have been said :) This couple celebrates their marriage with great dance. By the way, almost 22000 ukrainian couples got married since the beginning of the war in Ukraine. Love and peace will win! This model is driven manually by rotating a gear in back of the stand and can be motorised if you connect any motor you have to it. Given that the stand, groom and bride are separate models that work together, you can re-insert the bride and groom to make them rotate in the range you want. It also means you can use this stand to make your own brickheads "dance" as long as they have similar structure (all internal mechanics). Free building instruction: Rebrickable 2) Ukrainians A brave cossack; his younger brother; beatiful girl - they all can be the symbols of Ukraine. Let's take a closer look: This brave cossack has an earring in the left ear. Years ago it meant he was the one and only son of his mother. He wears traditional cossack pants - "sharovary" and traditional shirt - "vishivanka". Also, his hairstyle is called "oseledets" or "chub". Animation: Young girl. She also wears traditional combination of jacket and an embroidered skirt. Her flower wreath with colored ribbons is a symbol of youth and girlhood. Animation: Baby cossack - a symbol of ukrainian kids. Animation: Free buiding instructions: Rebrickable 3) Iron man with glow effect Animation: To use him as a pocket defender or just as a nightlight - it's up to you) It's a rework of set #41604, if you already have it - that's at least 40% of needed parts. You can use any PF-compatible power source to make it glow (such as 8881, 88000, 8878 and others). Free building instruction: Rebrickable 4) Ghost rider with glow effect Animation (without a chain): When it's cold, when it's dark, when there is no hope... Here is our hero - he brings light, warmth and hope for better times! You can use any PF-compatible power source to make it glow (such as 8881, 88000, 8878 and others). Free building instruction: Rebrickable 5) Polar four It's not just a company of polar habitants - it's a family: dad, mom, son and a cute bear cub in a sweater that, I bet, behaves and is perceived as a second son :) Animation: Animation: Animation: Animation: Also, you can build a silmplier and less parts-hungry version of a bear cub (without embroidery on the sweater): Free building instructions: Rebrickable 6) Popeye the Sailor Animation: Give this guy a spinach - and he will do an impossible! Free building instructions: Rebrickable 7) Athlete Animation: For all the lovers of fitness, dark glasses and pants with stripes :) Free building instructions: Rebrickable 8) Wolverine Animation: Friendly, polite, gentleman - all this is not about him. Strong, incredibly hardy, an excellent fighter - that's him! Now he can be your personal Jesu... bodyguard! :) Free building instructions: Rebrickable 9) Batbaby Animation: I'm sure he will nicely fit into the Batman's universe. Free building instructions: Rebrickable 10) Antique warrior Animation: A brave warrior is ready to protect you!

  11. Full RC Conversion of 10269 Harley Davidson Fatboy After many hours of trial and error, broken bits and gray hair I have finally a working Remote Controlled Harley. And it actually works wery well and are not more fragile than the orginal set. My goal was to create a slower motorbike that you can play with in your living room, so self balancing was not an option as this requires high speed to work. My bike runs on "training wheels" all the time that leans at the same time as the handlebar stears. Have tried my best to hide the electronics an keep it as close looking as possible to the orginal set. Motorized wtih Buwizz/CaDa battery to save space and Power Functions motors. Youtube Video Instructions available at Rebrickable
  12. I made the 2021 LEGO 76240 Batman Tumbler drive (again) and upgraded the looks to be more real. full remote controlled motorization (drive and steer) independend suspension (front: moving liftarms!) moving front armour plates as in movie retractable roof complete do-over of side armor plates: finaly polygons very close to the movie (not flat as LEGO did it) front gunner seat "hydraulics" finally as in movie winglets fixed on both ends now (no loose parts as from LEGO) Mind the Gap - closed that gap between the rear tires (i think in danish LEGO rhymes on lazy ;) Instructions on rebrickable: https://rebrickable.com/mocs/MOC-95123 I already did this with the 2014 version. Actually it was my first LEGO set in years. But I was never really happy with this. There were still too many flaws (as with the 2021 version) This time i wanted it to look more close to the original, finally. So I upgraded the armour and some other details a bit, to fix LEGO's little flaws. This is the LEGO Tumbler Batmobile, I always wanted.
  13. Hello everyone, let me introduce my latest creation. Ever since I get 42093 corvette I had an idea to disassemble it and use all this parts to create something playable and offroad capable. This 1:15 model of legendary F-150 truck was made with Power Functions elements and Sbrick for future truck trial competion or just for indoor fun (because of the weight (1250 g) I think this is not very competitive truck). It was a long project for me because of time constraints so I had started it before LEGO release their bigger one. This model has 4WD transmission with 2 L-motors driving each axle separetly (driving ratio - 3,5:1), servo motor for steering. Front suspension is independent double wishbone, rear is live axle with panara link. The model has openable doors, sunroof, hood and tailgate. Instructions in pdf were made in Stud io (my first experience with this software so it took a long time). Link for instructions: https://reb.li/m/93403 Also I created some additional color options with available parts. I hope to add instructions for those and the video with the orignal orange one later.
  14. I bought a set from bricklink a while ago and tested out the electronics, only to find that they were acting really strange. I'll try to explain it is as clear as possible but i may mess up a bit. So the set came with 4 motors, one of each kind, XL, L, M and Servo, and these all work perfectly fine on my own battery packs and recievers. But now i hook them up to the included recievers, so XL on red, L on blue, but then only the XL motor works. Now i'll switch them arround, but yet again it's only the XL motor that works, but now on the red channel. The L motor does function correctly when hooked up to a different reciever or straight to a battery pack. Further testing shows the XL motor works on all my recievers, both red and blue channels. The L motor works on 2 out of 4 recievers but only on either red or blu side, not both sides on the same reciever The Servo motor worked on none. And the M motor worked on 3 out of 4, also on just one side per reciever, either red or blue. And again all the motors work directly on the battery pack, or when hooked up to known good reciever. So what's going on here? How does one motor work on a reciever, but another does not? Can i throw away the motors or are the recievers at fault here? It's really frustrating because i am in the midst of making a deal with the seller aswell, but i can't without knowing exactly what's broken. It's like the recievers are picky in which motors they want to actuate and which ones not, but how's that even possible?

  16. Hello My first post here. Found some posts regarding the comparison of Powered Up (PU) and Power Functions (PF), but it was rather related to Technic. Couldn't find any similar for trains. So I am considering to buy 60198 Lego Cargo Train which is powered by Powered Up. However, I read here about PU system that it is inferior to PF system, as considering it in LEGO Technic. So how it is in the Trains department? As far as I see: PF for trains has remote IR intutitive controller with two knobs; for A channel and B channel with max. 8 trains to control (with 4 controllers). Additionally battery box and seperated IR recevier is needed. PU has bluetooth remote controller, so clunky smartphone control can be omitted? But is PU remote controller in any point inferior to older PF controller? PU battery box has embedd bt receiver so less space is needed inside the locomotive, so it seems its better (less flexible though?) Coming back to 60198 buying consideration; I saw some offers of used PF systems for trains (separated or with a locomotive), but they are quite pricey: 55 EU for control set, and 100EU with control+locomotive (from 60052 or 7939 set). So is it better to buy this new set with PU or invest into older used (but better?) PF sets? Kind regards

  19. Hey folks, another Motorization: all Functions of the 1989 Batmobile (LEGO 76139) RC controlled - yep the Batman again... Without sacrificing any of the nice details: Cockpit is still there, steering wheel works, just all motor driven and I motorized the guns and the roof and even made a tailored sbrick profile. Building instructions: Motorized LEGO 1989 Batmobile on rebrickable Driven by 2 LEGO Power Functions L-Motors (1:1 transmission) steered by a LEGO Power Functions Servo Motor guns engaged/disengaged by Motor roof opened/closed by Motor special Sbrick profile with programmig and grafics included a lot of space for up to 2 battery boxes/control hubs easily reachable under the trunk hatch (details on my rebrickable MOC page) Watch a Review of my motorized 1989 Batmobile on youtube: The Batmobile from Tim Burton's Batman 1989 with Michael Keaton is definitely one of the coolest, it's not as funky as the 1960s TV version and not as tank as the Nolan version but in my opinion it's simply a beaute! The 1989 Batmobile is using over 3,300 pieces, and over 60cm long. I added a few hundred bricks, mainly LEGO Technic and reused some others. So I ended up with over 3500 parts and (batteries included) almost 3.5 kg. That's heavy! So I needed a powerfull drive. I was thinking about the buggy motors but these are large and I wanted to put the batteries into the trunk. So i went for a pair of LEGO Power Functions L-Motors. These are some of the strongest LEGO motors and very small and efficient for their power and speed. The 1989 Batmobile is sleak and lies very deep on the road so it is geometrically impossible to move up any small hills (or even carpets). It will get stuck with its floor height of less then a brick. So it will only drive on a flat surface anyway. So it can be build for speed instead of torque power which the 1:1 transmission of the two L-Motors will do: It's a speed build, literally. One reason to put the batteries into the trunk was, to reach it easily for changing/recharging or simply switching on. Another reason was, to not put them into the beautifull cockpit with its nice self opening windshield - self opening? Yes, now it is motor driven ofcourse. And you hardly see the mechanics on the floor. Okay, the Batman minifigure included is way too small for the car but I found a Batman LEGO LED light, that fits into the car. Just be carefull when closing the cockpit to not get stuck. Slide-open is no problem. The car’s turbine exhaust by the way does not drive the machine guns anymore (it does in the original) because now a motor engages them. So I could make the jet exhaust it look like a real jet engine - the only exterior I changed. To make the two machine guns hidden, under the hood pop up, just press a button now. The Batmobile comes with nice little Bat emblems printed on the wheel rim - try not to lose them while driving, they are rare parts. The set of specially designed tyres for the front wheels is steered in a very specific geometry. I took care to keep that working the exact same way because it works very well for steering. The Build was complicated, took me weeks to get it right. I didnt want to change the exterior and as few as possible from the cockpit. You shouldnt see the opening mechanics. And I wanted to have all the features working, even the steering wheel (though steering is handled by a servo motor now) Every time I thought I got it, something else made problems, untill finally it all worked out. You can skip the trial and error (and breaking old LEGO gears) part: I made instructions and made them easily readable, so you can have it speed build in no time. I believe everyone should be able to build a LEGO set and try to make my instructions like that. Now it's hard to say, which one is the best batmobile motorization I ever made: The Lego 76139 1989 UCS Batmobile has more functions: motor driven MGs and a motor driven roof, the remote controlled motorized Lego 76023 UCS Tumbler I modded however has a full steerable front suspension for the independen wheels. my special Sbrick profile with some automated scripts is included I even made a cable layout for the power functions cables and extentions if you ended down here you may also be interested in or
  20. I finally did it, I've built a Volvo. It took me little more than a month to design, collect parts and build it, which is pretty short for my standards, I usually take (or loose) more time to fully complete a MOC of these proportions. The scale is, roughly, 1/20 and it has some functional features. Using LEGO power functions the vehicle can drive, steer, lift its 2nd drive axle, flash its beacon lights and operate the hooklift system. To be perfectly honest, not all of its features work the way I wanted them to work. The chassis was a bit small to incorporate all of these functions. I may design a new chassis at some point (more of that below) For me the highlight of this model is the cab really, getting the proportions of an FH right was a challenge, I had to make many compromises, choose the lesser of two evils. Of all truck brands, the Volvo just has the most complex design to replicate in the brick. But that is of course because a Volvo is the most pretty truck of them all after all. As I am employed at Volvo Trucks I simply had to build Volvo’s flagship. When Covid is over, I’ll drive it around the office landscape :). You may have noticed, the cab is not a square box, I spent a lot of time figuring out how to best approach the silhouette of the FH cab. It gets slightly more narrow higher up. The chassis is packed, I had to fit the battery box and two receivers in the cab, which is one of the reasons why there's no interior. Now, I'm sure some of you will most certainly have some suspicions about the feasibility of my hooklift system here... And they would be right! To be honest, the hooklift doesn't work all that well, lifting a container is a bit too much. It was only after I had completed the chassis that I learned about some sort of quality problem with those linear actuators I've used. But I think the fact that the very short leverage to rotate the hooklift may also have something to do with it. That of course was a consequence of the limited stroke of these actuators. This calls for the new longer actuators! ... However, that means I'll have to completely redesign the chassis... I have a couple of WIP pictures that I may share later. I hope you like it!
  21. Hello everyone, I have purchased a lego power functions led light on Bricklink, to light up my 42043 MB Arocs. On real life trucks you often see that the rear lights are ‘double’. I modified the rear bumper of the Arocs to create this ‘double’ lights. But, the Lego LED light has only one light bulb for every side, so it will not shine trough two holes of a technic liftarm. Anyone any ideas how to achieve this?
  22. Hi everyone, I've finished trying to RC my 42043 and it seems that the PF L motor has issues providing sufficient power to drive the set? I obtained instructions from the creator of this video (https://www.youtube.com/watch?v=BpP_05uxKqs&t=22s&ab_channel=PawełWojnarowski) and also checked PPUNG DADDY's 42043 RC video (https://www.youtube.com/watch?v=O8easq7ueIo&ab_channel=PPUNGDADDY(뿡대디)-LEGOTECHNICRC), both used an L motor with no problems. Here's a video of the issue: https://youtu.be/J8P13WLPzN8. As you can see in the video, the motor loses power after driving for some time, eventually being unable to drive at all. The problem is worsened when I try to drive and steer at the same time, it's almost impossible to drive and turn. I have tried swapping the tyres around, changing batteries, trying a V1 and V2 IR receiver, switching positions of the motor and servo cables, and using a new L motor. But the problem still persists. Here's a photo of the L motor: Could it be because of excess friction introduced in the rear axles during construction? Because I noticed when I lifted up the rear axles, the motor spins the wheels at its standard rpm, BUT only 1 wheel on each axle spins, the other is stationary. Then when the wheels contact the floor, the motor suddenly seems to struggle with driving the thing. Hence I was thinking could it be that I built the differential too "tightly"? Appreciate any help from the technic experts in this forum, thanks in advance!
  23. Hello Eurobricker's I just wanted to show you one of my latest builds. Its an RC semi truck that has the ROOF based on a Scania Crew-cab! Love it or hate it here it is. Features Differential in the rear. Opening doors Spacious Cabin Detailed Interior Full RC L Motor and an M motor Working 5th wheel Easily removable battery box. Love it or hate it there it is. Please give me some feedback, I haven't made instructions yet as I don't know if anyone will be interested in building it!
  24. Hey guys, some time ago, I have coded an app for controlling Lego PF using the IR diode of your Android phone. It didn't really work well, but since this time I have learned a lot about programming and made a new app for you. It is a BETA version, but I hope that there will be no issues with it. Before installing this app please google whether your phone has an IR blaster, this app won't work on devices without an IR blaster (physically not possible). The channelswitch is not working right now, but I will add this feature soon. I would be happy about some feedback from you!
