[MOD] PF Conversions for C+ sets - Directory
Ngoc Nguyen posted a topic in LEGO Technic, Model Team and Scale Modeling
I already planned to open this topic back in March or April, but I got caught up in work and stuff. Recent discussions in the 42129 thread makes me feel that inow is the good time to start it. My vision for this thread is that it will be a directory that contains the PF conversion mods for all of the Control+ sets so far. I have created a few mods myself as well. And I'll try to keep the information organized by updating this first post. If you have any mods, feel free to contribute. This thread can also be the directory for Studio models for the C+ sets, so that anyone with a mod idea can give it a try. ------------------------------------------------------------------------------------------------------------------------------------------- 42099 Available PF mods on Rebrickable: https://rebrickable.com/mocs/MOC-28766/olivierz/4x4-x-treme-off-roader-42099-power-functions-base/#details ------------------------------------------------------------------------------------------------------------------------------------------- 42100 There is currently no PF conversion mod available on Rebrickable. I've designed two PF mods for this set in Studio, but I haven't published yet because I haven't made the mod instruction. They will be published later this year. The mods are: - Full RC PF conversion: This mod replaces two hubs with two PF battery boxes, replaces all motors with 7 L motors, and adds 4 RC receivers. - Motorized PF conversion: Because a big empty box with 7 motors engaged in direct transmission is boring, I want to add something more Technic-ish, more mechanically interesting. This mod removes all hubs and motors for the base, which makes slewing and driving manual, and add 1 PF battery box, 1 L-motor, and a gearbox with 4 multi-directional switches for the functions of the super structure. Thanks efferman for sharing the base 42100 Studio file. ------------------------------------------------------------------------------------------------------------------------------------------- 42109 My free mods: - L-motor steer: https://rebrickable.com/mocs/MOC-84883/nguyengiangoc/42109-pf-conversion-l-motor-steer/ - Servo-motor steer: https://rebrickable.com/mocs/MOC-84884/nguyengiangoc/42109-pf-conversion-servo-motor-steer/ Available mods on Rebrickable: https://rebrickable.com/mocs/MOC-40851/johnnym/42109-wpower-functions/ https://rebrickable.com/mocs/MOC-52954/l1anchu/power-functions-rally-car/ The following creation is not exactly a PF conversion mod for 42109, but it's a RC PF car model that has the roughly identical dimensions with 42109. https://rebrickable.com/mocs/MOC-44977/maestroosram/compact-rally-car/#details ------------------------------------------------------------------------------------------------------------------------------------------- 42114 My free mod: https://rebrickable.com/mocs/MOC-85933/nguyengiangoc/42114-pf-conversion-servo-motor-steer/ ------------------------------------------------------------------------------------------------------------------------------------------- 42124 My free mods: - L-motor steer: https://rebrickable.com/mocs/MOC-84954/nguyengiangoc/42124-pf-conversion-l-motor-steer/ - Servo-motor steer: https://rebrickable.com/mocs/MOC-84955/nguyengiangoc/42124-pf-conversion-servo-motor-steer/ ------------------------------------------------------------------------------------------------------------------------------------------- 42129 My free mods: - L-motor steer: https://rebrickable.com/mocs/MOC-84984/nguyengiangoc/42129-pf-conversion-l-motor-steer/ - Servo-motor steer: https://rebrickable.com/mocs/MOC-85004/nguyengiangoc/42129-pf-conversion-servo-motor-steer/#details -

CADA battery with 4 motor outputs and remote control
Ivan_M posted a topic in LEGO Technic, Model Team and Scale Modeling
I know there is a lot of buzz about Chineese clones nowadays, but this is not a clonning brand and the product is very different from BuWizz, only sharing its form factor with it. I have discussed it with @Jim and he gave me permission to make this topic. Please refrain from meaningless post that you hate anything from China and that you wouldn't buy this. Thank you I have stumbled across a very interesting piece of hardware recenty - rechargable battery with four motor outputs AND remote controller - CADA remote control. The most interesting feature is indeed dedicated controller, unlike buwizz/sbrick there is no need for smart phone. I guess video (taken by František Hajdekr) is better than words: I can only say FINALLY, the need for smart phone is what makes buwizz/sbrick unusable for me, I just want plain controller, ready in 1 second and recharchable battery. The biggest question is of course what kind of hardware is inside the BB. The only info is that the battery inside is Li-ion, no info about capacity. I'm also very interested in motor controlling chip. I don't expect it will be comparable in power with BuWizz, I expect it to be better verision of LEGO Li-pol battery. So if there is anyone here who already purchased it and is willing to open it to give us some details, I would appreciate it. -
[MOD] Defender 42110 chassis with motorization & gearbox
Th4ho posted a topic in LEGO Technic, Model Team and Scale Modeling
This is my MOD chassis for the LEGO Technic Land Rover Defender 42110 with motorization using PF motors. Features: - fully RC for driving, steering and gear selection - working V8 fake engine - driving by 2 PF L-motors - steering by PF servo motor - 2-speed gearbox (LO/HI), controlled by PF M-motor - AWD with a centre differential, including differential lock - the centre differential lock is auto engaged by the LO gear I hope you enjoy the video :-.) -
Hi, I am building next MOC based on model which can be found in the game Snowrunner. I picked KHAN 39 Marshall - it is based on real world vehicle - UAZ 3151. I would like to ask for your advice with one of my biggest problem in mocing - creating a decent looking body. When you see the photos and think "It doesn't look like UAZ..." then YES - you are right and: I wish to focus on body and look (I don't want to discuss functions here, they are there and they are fine). As you can see, the main color is picked (some parts in proper colors are missing, but is not a problem when bricklink is around, the same goes for some missing obvious parts), but any smaller recolors are possible. The biggest problem I have is the front grill. It looks almost ok, but as the grill for Jeep or Land Rover, not the UAZ. I tried to recreate UAZ grill, but I failed miserably. As you can see, there is no much space for it and I am also very pleased with perfect connection of the front and the hood and I definitely will keep that. Important factor is also the fact, that body needs to be as one piece, which can be easily removed, so the body demands some rigidity. Also I plan to add front and rear lights, but at first I need to be sure that the body is right. So, could you help me a little to improve the look so it would be closer to UAZ body look? :)

Hello, This is my first post. I built Wing Body Truck seven months ago. Then I knew that many people wants building instructions. Now it is available. Sorry for late, because I've worked alone! Total 4126 pcs. The weight of Truck is 4600g (with 6x Eneloop batteries). -
Best power supply for PF motors?
HectorMB posted a topic in LEGO Technic, Model Team and Scale Modeling
Hi everyone, I have been running all my models with standard AA-battery boxes (running with 2800 mA AA batteries). Now i am wondering if that, besides space saving AAA-boxes are able to deliver higher output or are better than AA-Boxes. And, in such case, any significant difference between rechargeable 8878 battery box and AAA-battery box? Many thanks! -
Hello everyone, I was trying to figure the below down on my own browsing forums, searching for answers, reading a lot of articles from last 2 years however I did not find strict answers to my questions. I am sorry if some answers were already posted here and I did not find them. As I am about to spend some serious money (for me personally as I am not rich) on Lego Technic and I want to be able to create custom machines later I feel like I HAVE TO decide between Power Functions and Powered Up. 1. Is (or will) Powered Up system be customizable using Lego official App or 3rd party app? Will I be able to use Power Up motors and customize them into different than original machine so it works? 2. Should I even be coinsidering Powered Up systems for future and creating custom machines? 3. Is Power Functions a better choice for now and for future for creating custom machines? Is it easier to customize controls? 4. Are there any news or leaks that Lego will allow to customize controls of new Powered Up motors? 5. Is Power Functions better for building custom machines than Powered Up? 6. Does BuWizz or Bricks going to support and customize Powered Up? I am sorry, it all feels so overwhelming as for a beginning person that has limited budget and needs to pick carefully and plan everything ahead.

[MOC] Airbus Eurocopter EC135 (Police helicopter)
T Lego posted a topic in LEGO Technic, Model Team and Scale Modeling
Hi everyone, I would like to present my latest creation to you: A lego technic helicopter inspired by the Eurocopter EC135, in particular the police version. The eurocopter is an iconic helicopter which is widely used by police, fire and ambulance services and for executive transport worldwide. In fact I see these fly over my city almost every day The model presented here is not a very identical copy of the real machine, because I always like to be a bit free with the styling. As a matter of fact this model is in the end more of a display model than something to play with. When I started this project I aimed for a relatively small and compact package with some PF comonents inside and A goodlooking bodywork. I think I found the right ballance between panels flex axles and connectors. - Dimensions: 47x13x22 Studs -Weight: 750 g -Rotor span: 47 studs -White and Dark Azure collor scheme -easy accessible PF AAA battery box -Motorized main rotor and tail rotor powered by a PF M motor -Clutch gears for safety -Tiltable rotor blades powered by a PF M motor -Controlled using a standard PF remote controller Designing the tail (rotor) was probaly the biggest nightmare of this model. All the curved shapes and angles made it very hard to put it together. On top of that, a driven axle had to be placed inside as well. The solotion regarding the tail rotor I came up with was to use a rubber band. I tried using gears as well but it turned out too bulky and very ugly. Another challenge was the Dark Azure collor scheme. Not many parts are available in this collor so that was a huge limitation as well, but in the end it looks much better then most other collors would on this model. And at last a shot together with my Audi RS1 which, despite being built in different scales, look very nice on the shelf next to each other. Also special thanks to everyone here on the forum who helped me with the design on my WIP topic. I won't make instructions for this model, but for my current WIP I will. Comments, feedback and questions are as usual highly appreciated! -
I've always enjoyed the off-centre-cab shape of the classic 7760, so no sooner had I bodged my own PF-9V battery connector then I started to build one. There ended up being very little in common with the original set other than the overall body/cab shape, but anyway. The colour scheme was dictated by A: my existing parts collection, because I'm a student and don't like buying things, and B: an attempt at what this loco would look like if the British Rail Civil Engineers had used one. I quite like using this grey-yellow-black livery on locomotives, because the black around the windows and doors make them stand out against the bodywork. The handrails either side of the cab don't really make sense, but the only LBG 1x1s I had available are either horizontal clips or headlight bricks, so I put them there anyway. The cab is actually fairly open inside, but there isn't really an interior unless you count lots of wires... The front bonnet ended up held in place by gravity and friction rather than stud connections; this makes it very easy to open in order to detach the battery from the connector, which is the only way to turn the model off! With the cab removed as well, we can see there really is just a big bundle of cables in there. The receiver is only half poking out into the rear bonnet, but signal reception is still fine. In building this model I stole plenty of parts from my 20T Brake Van (and yet still didn't have enough LBG 1x1 & 1x2 bricks, hence why the cab sides are so messy). This meant it needed rebuilding, and I'm actually happier with it now - it's lost the handrails, but the yellow banding is a lot more consistent around the ends. Finally, the loco with its short works train of a bogie flat, a general purpose crane and the brake van. And, as ever, the Bricksafe folder containing the photos and LDD file can be found here: https://bricksafe.com/pages/Collet22/7760-inspired-shunter. Thank you for reading; what do you think?

Question about PF motors and reciver
Arioh posted a topic in LEGO Technic, Model Team and Scale Modeling
Can someone clarify small question about PF L motors and V1 reciver? I know, that 2 PF L motors on one channel of V1 reciver are underperfoming. So here is the question. if i put 2 recivers in model, one purely for servo and second for motors, where each L motor use its own channel, does they would reach their proper speed, and would such combination safe for hard-coupled motors? I'm trying to make rc 42077, and have only V1 recivers and regular AA battery box. Thus question above. Or what is better for model of such scale and weight - 2 L motors, 1 XL or 2 XL motors? -
Another smart brick is in the making. Jason Alleman is one of the persons behind this initiative. This time the emphasis is on sound and lights. More info on Kickstarter: PFx Brick More info on: http://fxbricks.com/

[MOC] Recovery Vehicle/Tow Truck Mk II
D3K posted a topic in LEGO Technic, Model Team and Scale Modeling
Hi all! I finished this build yesterday, and am quite happy with the resulting model, so I took it out for some pictures today. Unfortunately the batteries in the model died out before I had a chance to film it, so I'll have to do that tomorrow (feel like I need to prove that all the functions actually do work on this one ) So here it is, the Tow Truck Mk II, a combination of a European truck with a typically American "rotator crane"(??) on the back (a Eurotator?) First some information regarding this MOC (of course, you don't have to read it ) As many of you might know, I built a pneumatic tow truck/recovery truck roughly two years ago, and a lot of you even seemed to like that model! When I finished that model, I wanted to make an RC PF version with the same functions and body, and I also wanted to make one powered by just one motor, with function switching gearboxes as the ones you see in most of the official non-RC PF sets released by TLG. Well, it only took about to years to get around to actually doing it! Due to the fundamentally different techniques building with pneumatics vs mechanical functions, some compromises had to be made, and some features could even be added! Firstly, this model has no suspension. The back of the model is pretty densely packed with axles and gears and functions, so fitting live axle suspension while maintaining a somewhat acceptable overall rigidity in the model was deemed impossible (for me) very early on. Also, du to the various functions going to the front, suspension there was not worth it either. Secondly, the swing-out outriggers of the original model from 2013 needed to be unnecessarily complicated, bulky, and not very strong, so I opted for an alternative solution. However, I did manage to make the fourth axle steered, something the 2013 model did not feature As you can see, it uses the genreal colour scheme and a lot of the stickered pieces from 8109. The model was initially all yellow, like the last one, but I wanted to spice things up a little, and am very happy with the resulting colours Okay, enough babbling, here are a couple of more pictures: In the above picture, everything is deployed/opened. The motorized functions are: 1. Tiltable cabin (small LA) 2. Front stabilizers/outriggers (small LAs) 3. Front winch 4. Middle outriggers (worm drives, self locking geometry) 5. Rear stabilizers/outriggers (small LAs) 6. Wheel lift elevation (small LAs) 7. Wheel lift extending (large LA) 8. Wheel lift tilting (small LA) 9. Crane rotation (worm drive) 10. Crane lifting (large LA) 11. Crane boom extending (worm drive/z8 gear/gear racks) 12. Crane winch Other features are: -Openable doors -Working V8 engine -Openable side- and rear panels (to access battery box, as well as some chains and attachments for the towing fork) -Proportional steering with Ackermann geometry on axles 1, 2 and 3. The crane superstructure has two gearboxes for the three functions up there. That means there is a constantly running single axle going through the turntable, and the cranes functions are selected up top. This allows for infinite rotation, with none of the cranes' functions being affected. Yeah, I know that bull barmight be ever so slightly overkill, but IMO it's not too bad It can even lift things directly in front of it Lastly, the underside shot: Also, for those who haven't seen them yet, here are a couple of quick renders showing the internals of the model: And with colour coding for the various functions All pictures and renders can be found in higher resolution in the appropriate Bricksafe folder. Overall I'm quite happy with the resulting model, but even though all functions work, at least one of them is not ideal (cabin tilt; I'm looking at you). Also, I feel the crane superstructure could be made more elegant. Anyway, hope to be able to make the video tomorrow! Comments, thoughts and criticism is as always appreciated! -
Hi there, I'd like to present a MOC I've been working on from time to time since a few months: It's a small RC buggy, something I'm missing from Lego: Pictures show the V2 model. An interactive 360° view of the V1 model (with different rear axle) is available here: http://pub.clusterd.net/lego/technic/mocs/buggy/ Steering: PF Servo motor Propulsion: PF L motor (geared up 28z => 20z => 12z which is good enough to drive on office carpet and short distances on thicker carpets with fresh batteries, it works great on smooth surfaces; 36z => 12z => 12z also works, but requires more power and works best on a smooth surface; RWD) I initially used it with a AAA battery box and V2 IR receiver (not shown in the V2 pictures above, where it will be fixed to the rear spoiler, the V1 model had it at a slightly different location), but the AA battery box also fits - though it looks not as good due to different mount points, and it will also be heavier then. I assume it will also work with the LiPo box and SBrick and I can - since a few weeks - confirm that it also works with a BuWizz, but then it's more something for outdoor areas, as it gets pretty quick in fast and ludicrous modes. I created the main chassis of the V1 model of this buggy during a long evening/night and added most of the body parts the following day or days, don't remember exactly. The stickers are from the 8048 set and IMO fit the buggy theme great. Steering is also from 8048. It's fun to drive around and it can also take some hits. I took inspiration (mainly for the rear shock mounting and general setup) and motivation (I wanted to have something about as small as this) mainly from this video on YT: ...and some other videos about small RC buggies. The creator's buggy itself is also roughly based on the MOC (video and instructions for V1 model) of someone else. Instead of (re)building this one, I created my own - also because I didn't have a Buggy motor at that time. I also created a V3 model. It's slightly bigger, has front lights (using PF LEDs) and uses bigger wheels but shows some deficiencies of the design: The rear axle tends to tear itself apart in this model on rough surfaces, making the gears slip. I assume this is due to the bigger wheels used in the V3 model. I use some additional axles with stop and bushes now to hold the rear axle together for a longer time. I assume this maybe could be fixed by using a frame around the two axle holes that shouldn't move apart. When doing tight turns the V3 also lifts one of the front wheels - the one on the same side as the gear that sits on the drive axle. If someone has a good explanation for this, I'd be grateful. I suspect the softer shocks compared to V2.

[ Movie ] "Excavengers" battle (PF vs Control+)
cyberdyne systems posted a topic in LEGO Technic, Model Team and Scale Modeling
Soon after I've got my 42100, I decided to use it for making something epic and funny. So, after a month of work I've made this "movie" which tells a story about the last battle between old and new. Don't take it too serious, just have fun! P.S. Moral of the story is that the winner hasn't won at all. Cos' all the fallen gained an ability to be revived into different models and live forever, but the winner will stay useless and untouched. :) -

Hi everyone. I was wondering if anyone has any experience with taking a 9v battery plug and joining it with a PF wire. Just like this MiniZip. Any suggestions, tutorials, or discussion is much appreciated. Thanks.
-
A few of you, e.g. @Toastie regretted we removed the PF connectors from our Power Brick for the control buttons. To overcome that modification, we just released a small PF power box that allows you to run your PF devices from the power grid; you no longer need a PF battery box and replace / recharge batteries. We tried to keep it as simple and small as possible. There are two PF connectors; they both provide 9V power (GND and 9V pin) and full motor power (C1 and C2 pin): one connector provides clockwise motor power, the other counterclockwise motor power. You can control the motor power by adding an IR receiver and use your PF remotes. You can connect multiple motors spinning in the same direction by stacking the PF cables. It comes with an 9V/2A power adapter. We can provide the adapter with a US, EU, UK or AU plug. You can see it in action on the video below: It's currently available in our US/International webshop, it's going to become available in our European bricklink shop in the near future. Let us know what you think!

[WIP] 42110 MOD by Romashkaman
romashkaman posted a topic in LEGO Technic, Model Team and Scale Modeling
Hello all! I know, there already exists a topic about 42110 MODs. But, considering I plan to rebuild the whole car (except exterior) - it really would be better to separate my posts in a new topic (I agree with @Nazgarot). So, for now, I just copy what I posted in 42110 - Land Rover Defender - MODs and Improvements. The actual progress is: - completed front part of the frame (it's stiff enough even without any other part of the body attached): - McPherson suspension and front differential module mounts on that frame and is easily detachable (also McPherson struts include new cv-joints from 42099): - front suspension is built with caster and KPI angles: - engine is built from 4 PF XL-motors coupled together (output gear ratio is 20:36), also it's equipped with one-way clutch (it's built years ago by @nicjasno): - given that drive shaft of the engine has half-stud offset in vertical direction, here is an "offset remover": All modules assembled look like this: And, of course, a video of the short test: This module has some little issues (at first, I need to improve stiffness of the suspension's struts - under load they bend a little bit inward, but it doesn't affect all the process of a drive), but it has a really stiff frame and it's a good start point. You can find more photos on Flickr. About the question why I decided to use XL-motors: XL-s have the biggest torque among all Lego motors (according to the @Philo's page). Buggy-motor has higher rpms, but lower torque (and it's much more expensive and bigger than XL). It's not good choice for heavy vehicles. L-motors are more compact, but, again, if you compare torque/rpm ratio among all of the motors - XLs are the best imho. I tested this setup (4 XLs) two years ago at local fest: This model hadn't any gearbox and was pretty heavy. But, as you can see, the car accelerated easily, than acceleration stopped and speed was constant - only because of low max RPMs of the XLs. Theese motors have very good potential even without gearbox. L-motors are too weak for such acceleration of heavy models. Considering I plan to add a gearbox to this rebuilt Defender - it has to be fast and powerfull)) -

Let me introduce my latest build: Truck with concrete pump Introduction I got the inspiration for this kind of truck very long ago from this spectacular build from Waler: http://www.brickshelf.com/cgi-bin/gallery.cgi?f=558238 . It was one of the first builds I saw when my dark age ended and I kept returning to it ever since. I knew I had to build my own when the time is right. I tried it once already (not published) in smaller scale 3 years ago but I wasn't skilled enough, the scale was wrong and I lacked the parts. I hope it is better this time. I also knew that I want to build it with very different features, Waller's truck if fully RC and I have found out that I prefer single motor and gearbox and steering and drive. IMGP5397 Features & build The list of features I wanted to implement were clear from the begining - full suspension, one motor for 6 functions, 3-section pneumatic arm, gearbox with two way switches and modular build. I wanted similar build/experience like Arocs so I have borrowed few features from it, most important is the way how the 3 modules (front axles with cabin and "crane", central gearbox, rear axles) are connected together. So I took the size of the gear box and its attachment points from Arocs and made my own one within the limits. Later I had to drop the 6th output that was supposed to drive some sort of lever ("pump") inside of the hopper because of complexity. The first iteration of the gearbox was quite fine, but it struggled when the long outriggers were hood on it because I have used clutch gear before the whole gearbox. That was major flaw so I had rebuild it again (almost) from scratch and even managed to add second penumatic pump to it. Each function is proteced either by white clutch gear, rubber band or LA clutch. The gearbox is powered by one L-motor which is powerfull enough to drive everything. Concrete pump gearbox There are two switches on either side between the axles, on right there is switch for spreading outriggers and extending front ones, on left there is switch for lowering them and for pneumatic pump. Switch for arm rotation is under the turntable. The X-style outriggeres are as close to each other as possible. The problem is that the gears for the 4 mLA that spread outriggers have to turn in opposite direction on left/right side AND in opposite direction on front/rear side as well. You can probably see more from picture above. IMGP5404 IMGP5401 Rear axles are build in similar way like on arocs, the difference is that the springs are serured much better and there is build-in 1:3 reduction. Front axles are live axles with ackerman geometry and different steering angle. I'm really happy how they turned out, the spring is mounted to lower suspension arm so I was left with more space on chasis. The steering angle is very high at the cost of force required to steer. It is necessary to drive by one hand and steer by other one, the model is very heavy and steering at place is not very convenient. Rear axles are connected to V8 engine under the cabin. IMGP5414 The cabin can tilt to reveal engine. there are two seats (of course in blue), dahsboard, gear stick and two pedals inside. I have also added screen wipers and all mirrors. Arm is 3 sections. This was real science to make it as long as possible and light so the pistons can lift it. I have moved the pistons that operate 2nd and third section to opposite direction of the arm. This prooved very effective as it allowed me to make both sections at least 10 studs longer. I also wanted tubbing as nice as possible and thick tube for concrete as well.

We got our control buttons out! You can see them in action in the video below. We got a fair amount of feedback on our initial design of the control buttons. One to the main requests that came up was the possibility to use the buttons in combination with our nControl™ software. That was not part of the initial plan and the buttons were not designed for that. However, there are indeed applications where it makes sense to link the buttons to the software. Now that we have a web interface this would, for example, allow you to control the layout with the buttons but monitor it on a tablet. As such we decided to redesign the control buttons so the same buttons can be used: in a stand-alone way like our initial design in combination with nControl™ through a WiFi or USB link with the computer running the software (the buttons are ready for that, but the WiFi/USB brick still have to be finalized) Another major question was how many buttons could be linked into a control panel. The limiting factor is the power consumption of the buttons and that’s tricky because the power consumption depends on the type of button and how it’s used. The original power brick also had two PF1.0 connectors but as The LEGO Group is moving towards PF2.0/PU that doesn’t make much sense anymore. As such we redesigned the power brick: remove the PF1.0 connectors add a power sensor that drives a variable color LED. The color of the LED will change in function of the power consumption: green > red > red blinking. The following bricks / buttons are currently available: power brick servo motor control button for switches, boom barrier, decouplers, monorail switches. light control button for traffic lights and level crossing lights. The next step will be to create: WiFi Brick or USB brick to link the control panel with nControl™ a ‘Throttle Button’ to pilot the trains. This would control the trains through nControl™ and support our WiFi controller, LEGO PU controller and SBrick. Let us know what you think!
