Can I finally program power functions?
AI toothbrush posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
So I bought an rcx 2.0 and have some power functions extension cables that can also convert between PF and 9v. If I would connect PF to an rcx would it work? -
motorized, Lego 76023 Tumbler, Remote Controlled Batmobile with power functions
recklessGlitch posted a topic in LEGO Licensed
Hi folks, I made a motorization for the good old big Batman Tumbler, if youre interested, seems to be the only one out there, the instructions and details are here. full front suspension with moving swing arms (those big things in the front that hold the wheels, like in the movies) Power Functions servo motor steering system, nicely hidden so you won't see it through the windows or in the front what's more powerful than an L-engine and faster than a XL-engine? Right, two L-engines! This motorisation retrofit is fun! Differential for the back axle, with those big wheels you will need it all gears run stable, no cracking suspension for the back axis using springs of the same size as those pseudo springs from the original set a retractable roof (no separate roof parts like in the original) a few other small modifications to make it look a bit closer to the original and make it more sturdy not to lose parts while working very stable frame -
Mindstorms EV3+ Power Functions
Newest_Tech320 posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Does anyone know of an app or application that works with the old ev3 Mindstorms and technic power functions? -
You can find a sneak preview od the 3D printed sample on our IG: https://www.instagram.com/p/CLAKIt3B0PG/ Performance is around 10% faster RPM and torque compared to the 5292 motor (cca 20% more power). The polyfuse protection will be increased from 0,9 A to around 1,35 A - still testing the balance between performance and longetivity. Improved attachment possiblities, everything fits as it should in the studless building system The final version color will be between LGB and DBG. It will come with a 30 cm long PF cable plug, so it's compatible with BuWizz 2.0 and PF. Preorder here: https://buwizz.com/shop/buwizz-motor/ More info when it becomes available.

[Mod] RC Motorized Ghostbusters 10274 Ecto-1 with Powered Up
recklessGlitch posted a topic in LEGO Licensed
I got the Ecto for christmas and I felt the urge to squeeze in some remote controlled Motors. The new Powered Up have just the thing (although they are badly documented) One month after christmas I had it up and running. Tell me what you think. • quasi invisible • minimal invasive - all gadgets work • Battery replacement with no dissambling • light and sound kit still fits in • Lego POWERED UP Bluetooth Remote Control • no discontinued Power Functions • complete Instructions on rebrickable I made my first video about that: For this motorization I used LEGO's Powered Up Large Technic Motor for steering. That thing is just made to be used for the steering. It can act like a servo, because it has an internal position sensor. It is slim and dark bluish gray so it replaces that kardan drive below the front seat perfectly. Aditionally I didn't want to take it appart every time I change the batteries, so you can reacht it from the bottom. -
[MOC] All-Terrain Winter Expedition Vehicle
teetertater posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hello EB! I'd like to humbly show this remote control (PF) winter expedition vehicle (MOC). Featuring 4 independently driven tracks with a unique steering system. More explanation below and in my YouTube video. It has many issues that I'm not willing to spend more time to fix, but I've learned a lot from the process, which will help improve my future MOCs. If I was to start from scratch here's what I would change: Put motors closer to driven axles Split drivelines into either front/back or single motor per tread less complicated steering system Use a different type of suspension instead of pendular raise the height of the driven sprocket instead of extending driveline with gears reduce weight with panels vs lifttarms (I didn't have any at the time of building) Never use an Adder again, or if I really have to then use the old-style 24t differentials Work more on the cabin/exterior design A sizeable portion of the issues stemmed from the weight, which is something I didn't expect! I ordered some parts to allow me to finish the frame, and added design elements in the meantime. The design elements were pretty much the difference between being-able-to-carry-its-own-weight and not. The MOC is already disassembled, but I'll be happy to hear feedback and suggestions! -
My latest creation, Galaxy Cliff Lighthouse, reflects a desire to create an autobiographical MOC to share joy and pain non-verbally. It was inspired aesthetically by Split Rock Lighthouse on Lake Superior, thematically by Voyage of Life (1842) by Thomas Cole, and structurally by Obelisk Overpass, Boulder Dam, plus an early draft of River Wheel (featuring pirate ship gondolas rather than lumber). In fact, the 96 x 96-stud plot vacated by the dismantled River Wheel fed my drive to combine structures absent from my Lego city—a bridge, dam, and Ferris wheel. As you may imagine from the photos, a hilltop lighthouse teeters over an ocean, beneath a collection of galaxies spiraling through the nighttime sky, while a shooting star passes overhead. The light and dark figurative sailboats represent positive and negative memories, while the logarithmic spiral of galaxies in the sky is reflected in the earth below by the failed attempt of humankind to overcome the nature of life itself. Stats 26400 pieces 75 lbs (34 kg) Footprint: 96 or 128 square studs Volume: 156 x 156 x 176 studs Timeline Phase 1 Idea conceived: January 2020 Digital design: 8 weeks total Wheel: 2 weeks Lighthouse: 2 weeks Bridge: 2 days Cliff: 4 weeks Shipping: 13 weeks Building: 2 weeks Phase 2 Digital design revision: 1 week Shipping: 4* weeks Building: ongoing *Multiple international part orders in October never did arrive and had to be repurchased domestically.

NASA's 6x6 rover mobility system
jam8280 posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Robust working 1:12 RC model of the 6x6 rocker-bogie mobility system used in Mars rovers Perseverance and Curiosity... Tons of play value. Works well over most neighborhood surfaces and terrains, but sometimes gets stuck in loose sand. What you put on top is up to you. NB: The NASA rovers are 6x6x4 platforms, with 6 wheels, all 6 driven, and the 4 corner wheels steered. At 1:12 scale, steering individual wheels with LEGO motors is out of the question. So this model is necessarily a 6x6x0 platform — but one with reasonably effective skid steering. Several years ago, made a pretty faithful working 1:12 model of Curiosity with more emphasis on visual realism than on mobility system performance. The current model vastly outperforms the old one... Purist alert: SBrick RC receiver, non-LEGO elastics used to suppress wheel spread. -

For the last 5+ years I have been running a train under my Christmas tree, powered by a LiIon PF battery box and double motors. I recently answered a question on Bricks.stackexchange.com where someone asked for advice on which power system to buy, and the answer I had to give surprised me so much, that I went ahead and changed my own strategy immediately as well. I am now the proud owner of an oval (16+ curves, 12 straights) with a L+R set of points of 9V track, including transformer, wall wart and power-to-rail connectors. Total cost were around $120, however, this is after deducting the going BL price for other train components that came with my purchase. If I didn't exclude those, my total would have been $190. (All US dollars). This prompted me to do a quick compare on the costs of a fully working train oval for under a Christmas tree. The Oval consists of 16 curves and at least 8 straights. The cost of whatever Christmas train you choose to run is not included: Powered UP: Battery Box: $50 at LEGO S@H, $35+shipping at BrickLink (only 1 US Seller) Motor: $14 at LEGO S@H Wheels & Axles: ~$3+shipping on BrickLink for 2 axles and 4 wheels Decorative sides: ~$2.50+shipping on BrickLink Tracks: 1 Track Pack (8 straights, 4 curves): $20 at LEGO S@H, $16 on sale occasionally at other stores; 12x Curved tracks: $6+shipping at BL or: Buy set 60197 ($160 at LEGO S@H, occasionally on sale for less at other stores (e.g. currently $128 at Target) plus 4x Straight track ($7+Shipping on BL) - used ones run about the same cost as the promo prices. Depending on how you count, this is $100-$160+tax for this setup, and you need to keep a mobile phone around (or pony up another $15 for the remote control), have to keep the connection alive, and will have to replace/recharge batteries every 2-3hrs. Power Functions: Battery Box: $13 on LEGO S@H ($15+shipping on BL), or the LiIon pack which has no US-based sellers currently neither on EBay nor BL, but should go for $100-$150 if available. IR Receiver: $10+shipping for a used one on BrickLink Decorative sides: ~$2.50+shipping on BrickLink Tracks: 1 Track Pack (8 straights, 4 curves): $20 at LEGO S@H, $16 on sale occasionally at other stores; 12x Curved tracks: $6+shipping at BL or: Buy a retired Power Function set (used) such as 60051, which with patience can be bought used, complete on EBay for $125-$150. You'd need extra straight track though (see Powered Up), which runs ~$7+Shipping. Again, depending on how you count, this is a $70-$150 purchase. Likely the cheapest option currently, until prices for Power Functions start skyrocketing once all components have officially retired. You get 2-3hrs run time, and unless you add $100 to your total for a LiIon battery box, you will need to buy rechargeable batteries and a charger (or cycle through alkaline AAA's like a madman). 9V: Get a used but working copy of 4561 ($100-$150 on EBay) Buy some extra straight track: 4*$5+shipping on BL (let's call it $25) Total: $125-$175 Suddenly the convenience of never having to change batteries or recharge with a $150 9V purchase sounds pretty attractive, doesn't it? Quite fascinating, for a product that has been discontinued for almost 15 years.

Harry Potter Hogwarts Express Locomotive and Carriage MOC by dunkandeggbricks
dunkandegg posted a topic in LEGO Train Tech
Hello everyone!! I hope I'm right in making this a new topic - and that it should be in train tech and not in licensed. I've been working for a while on my own Hogwarts Express MOC. I know I'm not the first person to do this and I bow before many people who've done superb jobs - but here's my take on it! I've linked the two YouTube videos I've made about the locomotive and the carriage so feel free to have a watch. Or if not, there are a few photos which show what I've made. I'm very happy to answer any questions, as well as pointing people in the direction of my inspirations if they're looking for some themselves.

I would like to introduce my own control Solution: >>My Radio BLEuS << ( Bluetooth Low Energy useful System) Powered by Arduino Nano 33 BLE Sense, 4 x Power funtions port - 9V/1.5 A, each (optional updatable by that: Adafruit DRV8871 DC Motor Driver Breakout Board - 3.6A Max) --> Keep in mind the technical requirements to provide ~ 130W by using max, current simulanoiusly , at all ports ! Not realy needed for an ordinary Brickset Car. In A MOC i would recomend; Battery, ESC, and BL Motors taken from "real" RC Motor Sports section. power supply by PF Bat. box or internal 9V/ 1000 mAh Accu Internal Akku has USB charge connector. Control options: Infrared, by using PF IR Transmitter RC Transmitter(up to 4 channel) supporting, "AFHSD2A" LEGO Powered Up App LEGO Control+ Profiles Because of S-Brick published their protocol , it can be used with their mobile app , too. Because of, Brickcontroller 2 app works with any PU Hub, that is emulated by using profiles here, you can use Brickcontroller 2 app, also. Additions: SD Kart Slot for storing profiles , used by PU or Control+,...... Programming via USB Port, or JTAG connetor. Supported Frameworks: Arduino, MBED,Nordic SDK Note about Arduino Frameworks: Works with ArduinoBLE, as well as Adafruit BLUfruit Libraries by using Adafruit Bootloader.

[MOC] "Snowball" rc car
syclone posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Small rc car based off a design I came up in LDD 2 years ago (link, now with (in my eyes) slightly improved looks. Not a top-speed record breaker, a powerful tug-of-war winner vs a car, but a fun little thing to drive around. Originally everything came together off the fact that I wanted to drive the space wheels with a motor, everything else just came around. 2x m-motors w/ 1:2.084 final gear ratio and uses tank steering. To archieve small size a PF receiver with a Ni-MH 8'4V 20R8H format battery (the typical square 9v ones), which is quite underpowered (the cell might be dead too as it has been just lying around for a year or so). Probably can be BuWizz-ed with some drivetrain and body mods. I guess could also use one of those train controller blocks from PU/C+ (?) line if you've only got that system. lxf-file: download Video and a few pictures (same as from video slideshow) below. Mandatory belly shot: Cya! -

Motor Requirements for an RC Power Functions car
pjf1000 posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I'm designing an RC technic car (C8 Corvette) in Stud.io that I want to race against some other people. How many L-motors will I need to get the car up to a reasonable speed? (I'd like it to go around 5-10 mph, basically anything faster than a slow crawl). I have 2 L-motors built into the car right now, but I have a feeling they won't be powerful enough. I'm planning on using a BuWizz battery pack for power and bluetooth control. The car has around 1200 parts, so it probably weighs 3 pounds or so. I built a four speed sequential transmission into the car as well. For a car of this weight, should I use 4 L-motors? -
EDIT 08/22 - CURRENT STATE : Here is a truck I just made (well, it actually took me several days) while being confined. I don't like to take apart my sets on display to MOC so I had to do with just a bunch of spare part I had, hence the strange color scheme and some questionable building technics and aesthetic choices (for example, I didn't had anything to make the front radiator grill so i had to improvise...) I wanted to make an American style Truck, inspired by the 5571, 5591, 8285 and more recently 42078, and remote controlled so I can have a little fun with it. Please don't be to harsh, this is my first Technic MOC that didn't end at the prototype status. The original goal was to test my new Buwizz but I finally used only original Lego PF element, because I rather use a physical remote than a smartphone. It is powered by a L motor (with the drivetrain as follow : Motor---16T / 16T---20T / differential / 20T--20T / differential) ) and steered with a servo, with a decent speed and a good steering lock. The IR receiver and standard AA battery box are housed in the back of the cab, and the latest can slide up for replacement by tilting the foldable spoiler forward. The spoiler can also be folded all the way down to make the cabin roof flat. The doors can be opened and the hood can be lifted, even though there is no fake engine underneath because that's where I furst intended to put the Buwizz. (Actually there is still enough room for it so I could convert the truck to a Buwizz model and remove all the biggest section of the cab for a more lightweight truck. :-) I could also run an axle under the cabin to the engine compartment and run a fake engine from the exposed 16T gear... A lot of work, thoughts, trial and errors went into the building of this truck, so I hope you will enjoy it as much as I do. There is still A LOT room for improvement, but unfortunately I was limited by the parts I had. Almost all of my grey and black liftarms and technic connectors whereused in the process ! I am not entirely satisfied by the roof of the cabin in the IR receiver area, which is a bit messy, and I really wish I had DBG curved panel for the sides instead of LBG ones. And of course, I wish I could replace the ugly black plate at the front with a proper truck grill. I also have to add a fifth wheel, as it is not able to pull anything in this configuration. It should be easy anyway, as I have a lot of mounting option at the rear (the black panel is only there for aesthetic purpose). I just have to figure out something with the parts i have left... In the end I like very much how it turned out though, and I may consider a bricklink order to fix the aforementioned issues once the lock-down is over. In the mean time, any comment and suggestion for improvement is welcome ! :-) EDIT : now with a running fake engine ! -
Hello i would like too present you my next truck an MAN TGS 8X8 The model features 8X8 drive via 2XL motors with 4 Speed gearbox which is shiftet via 1 M motor. Steering is done via 1 Servo motor. The model was build for good offroad performance and high power, it weights around 3kg. The maximum slope it can do was 60% which is 30°. It is also able too drive in the garden in the sand. The challenge was building a strong drive train with a 4 speed gearbox in the small space. The front axles are pendular as well as the rear, i testet the front even with springs but pendular worked for me better in the terrain. The model can even be driven with pf ir receveirs and battery box. The tipping is done via 1 L motor and a self build worm gear drive because a linear actuator was too big. This model is powerd by an buwizz which works great but also was challenging because i switcht mid building too it which meant i had too redo the gearbox many times because of the new power. If you got any questions feel free to ask

PU and PF hybrid... PROWLER
Aurorasaurus posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
The idea with this is project is to get speed from buggy motors, and torque from PU XLs, which have a very convenient shape. Powering the hungry buggy motors from 2 buwizz units and the PU XLs from the big technic hub, which will be in the rear and controlling it with the buwizz app. Servo for steering, PU L for fake v8. Perfect car. I would enter it in the mad max contest but 2 things stop me. 1, I doubt I will finish in time and 2, I don’t have any real buggy motors and will be using fake ones. -
Hi all, wanted to share this MOC as I "teased" it many years ago but did not finish it until now. I started building the B1 in an effort to build the smallest possible 1:48 scale PF model, but ended up building the slightly smaller A6b, and then later on the even smaller EMD Model 40. Since then the B1 has been sitting in a folder on my computer gathering virtual dust. Last year someone inquired about the model and I decided to finish it once and for all, and this is the result: This is a pretty simple model just by virtue of the small size: the build is basically the same as that of the A6, just larger due to the larger scale size of the locomotive. It actually has a lot of volume compared to something like the Model 40, but the shape of LEGO motors and electronic components means that you can basically never fully utilize the 6-wide space in an 8-wide model. The part of the model that stumped me initially was connecting the massive side frames to the body. I had tried a couple times to find a solution over the years, but I finally cheated by cartooning the tanks on the sides of the locomotive with plates such that I could fit structural components behind them. The pantograph can also move up and down! Anyway, here is my video going into more detail about the model, as well as a Brickshelf gallery (when moderated). EDIT: Instructions for this model are now for sale on Rebrickable: https://rebrickable.com/mocs/MOC-48349/NonsenseWars/148-pennsylvania-railroad-b1-power-functions-9v

This and last year we got interesting Control+ electrical system that gave wider RC possibilities. They have a lot of advantages and disadvantages that were discussed here a lot in the different topics. My input here it the thing that still bothers me: The sets with motor(s), usually with a single one, purposed to move some actuators, rotate some turntables, give some air pressure (42053, 42055, for instance) Or their "manual" brothers that have the same functions powered by a manual knob(s) with possibility to add a motor to them (42029) So, why I'm talking about them? Just because these set categories have the thing that is common for them and looks useless and pointless without PF-motorization (not RC-control for drive&steer): the distribution and/or direction gearbox. You have a single motor and many levers that turns on and off some machinery functions powered by this motor. Alternatively, they have a single knob (which not very nice for play - rotate and rotate it moving some LAs, ughhh) but just made to be replaced with a motor. Other "pure-manual" sets have a lot of knobs - each for each own function, outrigger, winch, etc. One function - one knob. It is great for play with no motors, so you can raise the crane arm and release the rope at the same time just by spinning two opposite knobs (42108). My concern is, if we have Control+ as a PF replacement and still got no affordable and compact "static power source" (LiPo or a battery box) for a single Control+ motor, does it mean that we may have no "motorized" set with gearboxes in further? Updated 2020-01-30: soon we will know if 42113 Bell Osprey have a "dummy" power unit, or something else... So far we only know that the infographic presented on PoweredUp overview may be still actual. Notice the central section with a simple hub: -
[WIP] [Mod] 42109 w/Power Functions
johnnym posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hi there as nobody else yet presented a PF mod of the 42109 car (@ozacek?), I gave it a try yesterday afternoon/evening and did a quick & dirty PF mod. The result is a replica that's not totally identical in all details but comes very close to the original from the outside with considerable changes on the chassis. Differences: * Very obvious, the colors, but that was not important for the intended task. Initially I wanted to build it in red and black, but soon switched to orange and black and later just ignored the colors to save time when searching the needed parts - I have two many models built ATM and hence am low on some essential parts in the initially desired colors. The upcoming digital model(s) will use (a) more pleasing color combination(s). * The beam connecting both sides of the cockpit was moved 1 stud forward and was constructed differently to hold the PF AA battery box in place * As I couldn't find a position for the PF Servo motor that is low enough that the hood can be closed as much as in the original 42109, I used a 1 x 9 bent liftarm to fix the hood at an elevated position, imitating the look of a huge hood scoop. This way the hood is kept shut very tightly btw. * I used curved 11 x 3 panels with 2 pin holes for the side skirts, as I find them visually more pleasing then what was used in the original 42109. * The chassis is somewhat different: Instead of 11 x 7 frames I used 7 x 5 frames as I don't have 11 x 7 frames yet; 8L axles with stop for each rear wheel - so the axles can't be pulled out, but the wheels can still get loose, though I haven't seen this yet during driving and some other minor differences. The car doesn't use a differential but drives each rear wheel with a single PF L motor. Power Functions parts used: * 2 x PF L motor * 1 x PF Servo motor * 1 x PF IR V2 receiver - optional (not needed with BuWizz) * 1 x PF IR remote control - optional (not needed with BuWizz) * 1 x PF AA battery box - optional (not needed with BuWizz) [* 1 x PF control switch - actually not really needed, if the drive lines are set up in a way that both PF L motors can run in the same direction (not needed with BuWizz)] I.e. the PF equipment that came with the 9398 - not that I have one. Enough talking/writing, here are three shots, digital model(s) will come later: Using a BuWizz instead of the PF remote control equipment saves a lot of space and weight and will make this car faster. So far I haven't used it with fresh AA batteries but only with used AA batteries and a BuWizz and even in normal mode the car seems to be quicker, not to speak of fast and ludicrous modes, where the wheels start slipping on carpet and laminate floor when going backwards at full speed in fast mode or both ways at full speed in ludicrous mode.
