  1. After some month of building I like to show you my latest MOC: A Mercedes Zetros 6x6 truck. It is a ~ 1:13,5 scale model of the Mercedes Zetros 2733. All functions are Full RC. It is 69 cm long, 21 cm wide and has a height of 27,5 cm. The weight is 4553 g. As battery I use the BuWizz. The Zetros is remote controlled by 4 Sbricks via iPhone. Functions and used parts: Propulsion: 4 Lego Technic Buggy Motor Steering: 1 Lego PF Servo Diff Locks (front / rear axles + central lock): 1 Lego PF Servo 4 Lego Pneumatic V1 + V2 1x5 (Automatic) Compressor: 1 Lego PF L-Motor 4 Lego Pneumatic Pump (V2) Winch: 1 Lego PF L-Motor Telescope Crane: 1 Lego PF M-Motor 3 Lego PF Servo 3 Lego Pneumatic V2 Cylinder 2x11 2 Lego Pneumatic V2 Cylinder 1x11 Outriggers: 1 Lego PF Servo 1 Lego PF M-Motor 2 Lego Pneumatic V2 Cylinder 2x11 Lights: 10 pairs Lego PF LED plus several Lego extension wires Some more highlights: Full independent Multi link live axle suspension Portal Axes Planetary Gears Working head lights, rear lights and flood lights Working turn signals and warning lights [/url Edit: I nearly forgot some special picture pair ;) [/url] Second edit: I corrected the scale which I'd miscalculated.
  2. Recently we have seen quite a few PF Controllers popping up. Some more interesting than others. This project was launched on Kickstarter today and I think it's worth sharing. Since we are not fond of people promoting their Kickstarter or LEGO Ideas on Eurobricks, I have taken the liberty to promote this project myself. Kickstarter description A compact, high performance remote control system for LEGO® models. With embedded battery, precise servo control and huge power. Technical information BuWizz is a four channel high performance controller for LEGO® Power Functions, with embedded battery and a Micro-USB charging port. Paired over Bluetooth with smartphone or tablet, BuWizz is compact yet powerful. BuWizz: has 4 channels can be charged with any Micro-USB charger - even with a powerbank while you drive your model.- has several speed modes: in fast mode, the motors receive 2x more power than other solutions with LEGO batteries - enables great speed or better obstacle climbing - in slow mode, the PF servo motor can move very slow - for realistic motion of railway crossing gates, convertible roof, etc. can drive 2 XL motors on each channel in high speed mode- delivers 8 times more power (4 channels combined) than any solution with LEGO battery- is compact: 8x4x3 bricks size, 2x IR receivers footprint replaces battery box + 2x IR receivers can be embedded deep into your model - all you need is access to Micro-USB charging port powerful enough for large models, yet small enough to build a very compact model Dimensions It has the same dimensions as the rechargeable battery, which is quite convenient. Controls Example implementations Kickstarter Check out the project on Kickstarter Reviews Sariel has received a copy and he is quite enthusiastic. http://www.youtube.com/watch?v=cdPduWEk7H4 I will receive a copy soon, after which I will share my thoughts.
  3. The idea for this MOC came immediately when the Claas set was released. The tires were perfect. Now, I should clarify, I truly do not mean the title of “Redneck Truck” disparagingly. Also, although I am in Texas, despite my truest desires, I cannot in good conscience consider myself one with this crowd. I have never attended one of the mud-fests you see below. That is not said in defense, rather, out of jealously. The idea for this truck and the ensuing video came from watching youtube videos such as the one below and I could not help but notice how fun I thought they looked. Details of this build: - Weight: 1492 grams - Length: 43 studs - Width: 15 studs - Final drivetrain gear ratio: 7:1 (1.667:1 x 1.4:1 x 3:1) - Opening Hood, doors, tailgate - Working (fake) V10 engine - Full Suspension Really not much more to say. Truck is driven by two XL Motors, direct-coupled together. Powered by BuWizz. Steering is by one M motor. Steering motor and overall configuration are a little weird in that they are mounted very high. That was intentional. The purpose of the truck was to run in mud and water and since PF motors and electronics are not water proof they needed to be mounted high. The bodywork is a little bulky, but again, this was on purpose. I have noticed in my hours of wasting time (watching muddin’ videos) that these trucks are often older Chevy or Ford models that in real life have blockier, less-rounded bodies. So I tried to emulate that. Also, naturally, in a real-road worthy truck you would not have an engine halfway out, exposing cylinders, piston-heads, etc. Yet, Redneck Mudders aren’t really supposed to be logical or reflections of realism, so again that was all done on purpose. The engine was inspired by @BusterHaus. Fun build….. hope you enjoy the pics and video! More pics and details @ http://www.moc-pages.com/moc.php/441915
  4. I've been starting on the bodywork and have added a quick clip of a flush mounted door mechanism. I'll periodically add bits until it's done, enjoy (Above pic is a link to video) This is my current supercar WIP. It has fully independent suspension, torsion bar, cantilevered front, typical rear, and sway bars. steering with attached steering wheel one servo, drive 2x XL, custom miniature V12 engine on an AWD chassis with a remote driven four speed sequential gearbox powered by an M motor. Race jacks with remote compressor, adjustable rear wing, tilt steering wheel, pedals with feedback, adjustable with single lever tilt and slide seats.

  5. I had a long conversation with Roni of BuWizz fame about desirable vehicles used with his invention. Apart from electrifying large Lego technic vehicles, we were thinking about producing a simple and low-part-number vehicle, which can be quickly build and used. Well, this was the intention, however I was not very successful with this. I mean, it's not a problem regarding dimensions etc., but more of a general shape. My cars look like something from another world but not in a good sense. So, please Sariel and other well established builders, perhaps you could just skip this presentation:-) But then I have spotted Mini Mining Truck in 42055 and it seemed cute (perhaps I am a bit biased towards large models but small technic models are generally quite nice and full of features). Therefore I decided to motorized it. At first I've tried with Lego components but found out there is no room. Then I decided to use BuWizz, since allowed a bit smaller footprint. However, the truck kept growing in size. I have motorized the propulsion (I wanted to add the differential, however it kept the truck to slip while navigating rough terrain), steering and raising/lowering the dump. In addition I have also put in some lights, however BuWizz application at this moment does not support switches (hint, hint) so using lights is a bit of a drag. There are several issues I did not addressed properly: single back wheels (not enough room at this scale), not uniform color (lack of parts), cabin missing (I used the space for cables) etc. I have rebuild the d*mn thing at least 10 times but I guess this just speaks about my inability to do great technic job. Nevertheless, the truck moves and it's quite fun to play with. And I guess this is one of the main features.
  6. Hi! Two years ago, I had made a Gymkhana with Ken Block’s Ford Fiesta. It drifted well, but I wanted to do better using the BuWizz. So I decided to make a better chassis and pair it with the bodywork of the world’s best rally driver’s car : Sébastien loeb’s DS3! This new chassis‘ works in the same way as the old version, but it’s better at drifting. First of all, a reminder of how it works: When turning, the adherence at the rear axle is decreased. This is due to the caster angle of the front axle which lifts the rear interior wheel. (Like a karting il me semble qu’on dit a go-kart mais il faut vérifier!!) So, what changes with this new chassis compared to the old version? The caster angle is the same, but the swerve front wheels relative to their pivot point is decreased (?). The rigidity has been decreased, and the transmission has been upgraded. Now, it has less friction. The consequence is that the difference of adherence at the rear axle is smoother when turning, so drifting is more realistic. Furthermore, there is the amazing BuWizz power! However, the car isn’t easier to handle. (It takes a lot of time to control it perfectly) This car has got stickers, and building instructions! Both have been made by Thorsten Spelz, so thanks to him! Click here And now, the Gymkhana!
  7. Good day. For a long time I wanted to create a moc with various functions apart from steering and drive. Overview: -4x4 drive with 2 diffs -3 steering modes : rear only, crab and all-wheel steering -Boom ascention -Boom extention -Forks tilting -part count of approximately 1000 pieces The forks on the end of the boom were able to be replaced with another attachment by pulling out two 8l axles with stop. The cabin has on openable door , adjustable seat and a lever to switch steering modes. The steering is a very basic type, the front stering motor is attached to a switch , which neutralizes it's movement or decides the direction of steering. the boom is extended through a pulley system , which was done due to lack of 4 stud gearracks. total boom size being fully extended is of 60 studs. The video below shows basic functionality. Something I learned with this build is that I should stick with smaller size mocs and not to rush into medium sized model. All photos here
  8. Hello My ripsaw, inspired by Fast Furious 8 (but not a copy). Since Buwizz can handle 2x Buggy motors, I decided to build light and powerful tracked vehicle for snow. Vehicle for fun! Movie was filmed 3 month ago. We have summer now. TURN ON ENGLISH SUBTITLES I am not the first here with such powerful tracked vehicle. I can confrim that it is useless toy and hard to control. Thing for fun:) more photos http://bricksafe.com/pages/rm8/ripsaw Thank you for watching!
  9. Hi! When I received my BuWizz, I wanted to make a fast RC model. It had to be very light, so a kart was good to make that. The mechanic is very simple. There are just some gears to turn the wheels at a high speed. As you can see, the driving is powered by two L motors and the steering by a servomotor. According to the tyres, this kart is very fast!
  10. Good day. This is a trial truck using 1 XL motor for drive, 1 M motor for steering and powered by BuWizz. The drive is powered through a worm gear to 8t gear, creating a powerful 1:8 reduction. It uses model team wheels , they don't have the best perfomance, but it is good enough. For the bodywork I was inspired by ГАЗ-66 (gaz-66), although it isn't an exact copy. Both doors can be opened, the seats and steering wheel are adjustable LDD model available here: download
  11. Dear train community, a while ago, I presented my model of a small industrial shunting engine (for information about the prototype, and to compare the pictures below with version 1.0, please see here). However, although it proved to be a strong and reliable little locomotive, I was never entirely happy with it: The roof turned out to be very flimsy, and the battery box and IR receiver were completely blocking the view through the cab. So when BuWizz was announced, and I realized that its height would be considerably lower than that of 84599, and it would need no additional receiver, I thought I should give it a try and rebuild my MOC (even though this meant that I had to get a smartphone… ). The revised model has been completed for a couple of weeks now, but it wasn’t until last week that a BuWizz app version was released which allowed to control two output channels via one slider, so I couldn’t let the engine run until then… (By the way: One more thing that I would really wish for would be an option to „lock“ the slider in a given position, so that you don’t have to keep your finger on the phone all the time when the engine is running. Maybe someone from BuWizz will read this… ) Following alterations have been implemented: - BuWizz replacing the rechargeable battery box - boiler diameter increased by one plate for better scale accuracy and a brawnier appearance - slightly larger, smoother side tanks - revised colour scheme without black striping (thus adding to the stouter look) - additional small windows in the cab front - completely redesigned cab roof with more prototypical profile and no longer needing transparent plates to support the door openings - handrails below the buffer beams for the shunting men - strings as sand pipes - improved shape of the cylinders - smaller headlights - (at least rudimentary) cab interior thanks to the reduced height of BuWizz But unfortunately, still no opening doors – sorry, Sergio! (I promise my next model will have them. And it will be a BIG model. REALLY big!) With BuWizz set to „slow“ mode, gentle and precise shunting becomes possible; something one couldn’t even dream about while using Lego’s IR remote control system. (Click on the image to play video) As always, you will find larger versions of the images in my Bricksafe folder. The LDD file is available for download here, yet doesn’t show the final design of the cab roof. Comments are of course most welcome. Thanks for stopping by! Best regards, Sven
  12. Good day. This used to be one of my prototypes for the e formula competition. But after making the chassis I decided to put a BuWizz in . Backstory: "This is one of the best known racing cars on Xerox , developed by Xewyz Industries. Stabilized Zirum Crystals' energy is used to power it , obtaining constant and (almost) infinitely lasting power. It has a turbo system to increase the output speed." Real statistics: -2x m-motors for drive , with a 3:1 gear ratio -1x m-motor for return to center steering -BuWizz Using (underestimated now) m-motors , it picks up quite high speeds and is a lot of fun to drive around ,even in normal BuWizz mode. Here is a LDD model -> download A quick preview of what to expect whe the full video is finished: https://www.youtube.com/watch?v=GaVM6J2oFvI
  13. I'd like to share with you my upgraded version of the 42050 Drag Racer. First of all, 2 videos: I really liked the look of the 42050 set when I got it, I think it has all the main characteristics of a drag racer. On the functions' side I was not that satisfied, there were a couple of issues: - Simulated wheelie mode looks ok-ish while the model is standing, but it's really lame when you motorize it - official motorized version has manual on/off, you have to walk with the model to stop it. If you add an IR receiver steering still remains manual - M motor is weak to power a vehicle that supposed to be fast :) - Driver seat is small for a Technic guy, minifig fits but that's really out of scale The upgraded version has the following features: - body panels and stickers from 42041/8041 Race Truck - Servo motor for steering - 2 Buggy motors - 2 BuWizz units for maximum power and more weight - 1 M motor for powering the fake engine - Proper seat for the driver - Larger spoiler to add weight to the back – essential for the wheelies 🙂 I am quite satisfied with the result, the upgraded version is fast and most importantly it can do proper wheelies :) A couple of pictures of the build: I also built a drag racing Christmas tree for the videos. The Lego LED lights are controlled by 2 SBricks. The staging/start sequence is pre-programmed, I did not have all the necessary components to build a proper functioning one. I'll add some information and images later if you're interested. You can see some more pictures and additional information in my blog post
  14. Good day! About a year ago I made an APC . It was a simplistic, underpowered MOC. Today I present you my second attempt at building APC. It was slightly inspired by BOV m11 Functions: -4x4 drive with buggy motor with 1:4.4 gear ratio -steering with m-motor -turret rotation with m-motor -gun elevation with m-motor -powered by a BuWizz -pendular suspension on rear axle The off-road perfomance of the geared down buggy motor was surprisingly good , both at low and high speeds. The turret can rotate 360º freely with the motor geared down 1:2.3. The gun uses a mini LA for the elevation @ 1:1 gear ratio The charging port and the switch on the BuWizz are accesible throught the hatch on the left side of the vehicle. I hope my studded bodywork isn't too horrible , the video will be up later today.
  15. Hi everyone This is a model i built a while ago, but only now had the time and eqiupment to showcase. I was asked to build a Buwizz showcase model for a toy fair in Boogna, italy. After some thought I decided to combine the rare dark blue panels from 41999 with tracks and a couple of RC motors. The finished model has following features: 2 RC models for drive Spring supported pendular suspension Two working fake V8 engines - hence the V16 Rollcage reinforced interrior with 4 seats Openable 70's muscle car style openable bodywork A working winch LED bar powereed by a total of 10 LEDs So lets start with a 360 view of the model: As you can see the body is inspired by 70's muscle car styling with large chromed grill Detailed view of the grill with the cute bunny: Lifting up the body exposes the internal rollcage and the two massive engines: Further the rollcage can be lifted by pulling out the two red pins, showing the 4 identical seats, making this a perfect family car The two V8's are powered by the RC motor's faster output: The power passes via cardan axles under the seats and up the gears: In case the model ever gets stuck there is also a functional winch powered by an M motor via 1:5 gearing ratio: The suspension is highly flexible: And here is the most important photo of any technic model : And to finish up with a bang here's a video of the Ripster in action: A quick summary of my thoughts regarding this model: Because the tracks are powered by the RC motors directly this is THE fastest tracked model I ever had the pleasure of building. But that speed comes with a price, the model has problems steering on spot on surfaces with high friction such as carpets. Sudden acceleration on such surfaces with quite a heavy model like this (1,5 kg) can cause problems with tracks coming apart. For that reason this is a perfect vehicle for smooth surfaces or ice. It is also very good at drifting, though it takes a lot of coordination to control a tracked vehicle like this. Suspension is extremely durable, the wheels were originally held with frictionless pins, but that proved insufficient, so they were replaced by axles 5 with stops. After that upgrade I had zero issues with suspension and it proved to be very flexible, yet reliable. Biggest problem with the model is the cosmetic stuff, the V8 chains tend to slide off after a while at such high RPMs, the bunny likes to jump into oblivion and the front grill can fall apart when crashing into stuff. Oh and one last thing, ITS LOUD. Driving this on my floor sounds like machine gun fire, so I hope my neighbours wont file a complaint . At the end of the day even with its positives and negatives its a very fun model to drive around and that is all that matters.
  16. Good Day. I present to you my biggest MOC ever - a futuristic dakar truck. This is a project I have started back in February to make it in time to the arrrival of BuWizz , or that is what I had planned. For propulsion it is using only one buggy motor , what isn't the best idea because the motor ends overheating. But it is possible to install a second buggy motor with a bit of chassis re-design. To fill a bit the huge truck, I installed a X16 engine- courtesy of ZBLJ. The steering uses 1x m-motor , without any return-to-center mechanism thanks to the precise control with the BuWizz brick. The outside design was heavily inspired by 00's sets ( specially 8466) , and I included gull-wing doors with mini linear actuators . m-motors can be installed easily to motorize that function too, but I used two knobs on top of the cabin . The interior was kept simple - two bucket seats and a dashboard. I already shoot some footage , so a video will come soon. For now , here are some photos. 2017-04-30_05-28-06 by Alaxaf, on Flickr
  17. Hi guys, 8043 was THE SET that ended my dark ages and, until now, I was very reluctant to make any modifications to it. But, like many of you, I’ve just received my BuWizz and decided to use 8043 to get my first impressions of BuWizz:
  18. Hi guys! Here's a demonstration model I built to show the potential of Buwizz. There were several goals for this model: Keep it small and light Gearing should be as simple and efficient as possible - ended up using a 40 tooth gear powering the older style differential, getting a 40/:16 gear ratio Advanced steering solution - pivot point is inside the wheel and the car is using ackermann steering geometry for best possible steering and efficiency Use Buwizz as a structural support - not only does the Buwizz power and control the car, it also helds it together Working steering wheel and openable doors - have them too Here's the result: In the gif below you can see the way the car is built and how the steering system works The end result is a very fast and maneuverable car that faces same problems as the big ones. Its actually so fast, that its easy to understeer at high speed or oversteer when accelerating. Controling it at high speed can be very hard, but thanks to Buwiz's different speed modes you can easily slow down the car. This is very usefull for parking or precise maneuvering. To finish up with a bang, here's a video: If there will be enough demand I will create an LDD model of this little speed devil
  19. After trying out the BuWizz with a big 4x4 offroader I decided to try the other spectrum - speed. For this purpose I designed a very simple, but robust racing car. The main features: - Rear wheel drive powered by two RC motors - Rather hard independent suspesnion on all wheels including realistic caster angle in front for best directional stability - Use of old x873c01 hubs for lowest possible wobble and friction - 4 point reinforced suspension for highest steering accuracy - 4x Tumbler wheels for highest possible traction and cool factor - 1x BuWizz running in ludicrous mode, providing enough power for the model to reach 25 km/h And this is how it works in practice: So how did the model work out? Well as you can see the racer reached an amazing speed, and survived quite many jumps and crashes. The suspension held up suprisingly well and no drivelinecomponent of the rear wheel drive ever failed, even though the BuWizz powered the motors with enough juice to powerslide the massive tumbler wheels on concrete. All in the model was a blast to drive and seeing it jump over shallow ramps of the garage house was simply breathtaking. I hope the BuWizz becomes a reality, so I can make even faster, more powerfull version of such vehicles such as rally cars and trophy trucks
  20. Hello, some time ago, there was made a new topic on the Technic Forum about a new Power Functions controller of high performance called BuWizz As you can see, its principle is similar to the SBrick, but the advantage is that it has a power supply inside, which makes it a very compact controller with the same size of the rechargeable battery, i made this topic to let you know about this nice product, and also, if some of you are available to get one as a test, let us see how it performs in trains, it is also a project in Kickstarter More information at: Kickstarter https://www.kickstarter.com/projects/973645257/buwizz-remote-control-for-lego-models Technic Topic http://www.eurobricks.com/forum/index.php?showtopic=136273 BuWizz Page http://www.buwizz.com/
  21. Hi guys, I've had a chance to test a prototype of a BuWizz - an interesting device that combines remote control unit which allows controlling stuff with your phone AND a power supply which is surprisingly powerful. My video test is below, keep in mind that this is a prototype and you can make the finished product happen by supporting it at Kickstarter: https://www.kickstar...for-lego-models Project website: http://buwizz.com/
