Techniccrack

Hi, you asked me how i knew it was a Bugatti. Friend of mine has good connections to the Lego Group. I heard it 4 months ago the Technic team is creating something.. The only thing i knew it was Bugatti

so...what did i say i my previous post? Bugatti.... voila

its in Utrecht in october

I build this model for presentation on Legoworld in october here in Holland. Plans for another ride not yet. But if i finish this one succesfully with all the challenges and difficulties in this model, nothing can stop me for building more rides on this size

a little update. building the crosses on the arms

Iam sure that that will be fixed, bro :), there are several ways to do it

The big ball is nothing more than dressing up the lifthead (the part that connects the lift with the arms). iam still building that. No problem at all

The speed of the motors is adjustable. But maybe a will add a a few gears to make the speed just right so that i can activate it by a press of a button. The sudden stop i will look at it, but i think that wont be a big problem The middle structure is 21 studs wide.( the batterybox i added is just temporalily.). It "looks" to big but it will be look good with the crosses and seats added on the final model. The model will about 140 studs big Here is how the middle "ton" will look like for now (iam adjusting it a little now because of the new lift slider) Believe me, it wasnt easy to create the movement without weight problems and rotation issues:). i rebuild it maybe 12 times All credits to the curved gearbeams. that what made it possible

UPDATE I attached the arms (temporalily connection) to test the lifting of the Polyp. This is how it looks now (the batterybox on the side will be replaced by a old style 9 volt battery box, but i dont have the extensioncable to connect it to the receiver :( So i did a stability test and a speed test and...ofcourse the lifting when in full motion. The liftrod i replaced by a more stable structure. (the crosses with the seats are not ready, iam busy building those). This is test stage 2 of the machine: enjoy!

I made a video of how the rotating system operate. Pure a first stage test of rotation, lift and strength. Enjoy!

This week i will test the model. Rotating, lifting, speed, strength, all will be tested in a video patience:)

I think you misunderstood my comment. The seats (read: the crosses) DO rotate like that faller ride. The seats independently rotate due of the central force of the rotation.just like the real thing

Arm frames ready. Only dress up to cover the holes and lighting

mm, strange., i copy the bbcode with size 640 x 360 px. but i shall resize them They are resized. sorry. my mistake!

Control panel Everything on the model will be remote controlled. Movement, lifting, lighting A few years ago i build an controlpanel. (It will be modified a little) to be continued..

Arm endparts and electric linear dragcontact A little update The crosses and seats will be illuminated. So therefore a rotation electric contact is needed. For fix this "problem" i used a motorcilinderpart and a small DC connector that fits like a glove Parts i used to make the endparts of each arm: Building it: Wiring: The curved gear racks and perfect for a put the wire through As you can see below the two racks together will create a smal hole where i can put the wiring through to be continued..

A little modification: The driver that power the lighting must be mounted inside the lower cilinder. Due a drag contact it get his powersource from 12volts. However, the room i have inside the cilinder is to small. so i had to modify 2 arm supporters. In between the two, the driver fits perfectly. The fence around the center unit covers the driver. Here some photos

He there. The idea of the turntable is indeed not new. I saw a guy on Youtube who came up with the round bearings. All credit for him(Tanwooken YU). I tested the weight it can handle. I putted 10 kilograms on the turntable. No problem About the questions: The liftsystem us due to 2 horizontal 11 studs gear rack. It pushes the head upwards.(explained in my opening of this topic) The seats are not powerwd by a motor.. on the real thing the seats are moving independently cause of the centeal force of the rotation of the machine. The crosses are powered by connection to the second ring on the lower cilinder and for speed adjustments also by a motor About how many motors: The model has 2 xl motors to drive the lower cilinder 1 xl motor for rotation of the second cilinder. 1 xl motor for the lifting. 1 medium motor for rotation of the crosses The lightning will be EL wire.(chasing). And led strips around the model (on backplate)

A little update. i began to make the inner fence around the center unit here is what it will look like (photo taken before adding the arm connections)

The next supercar will be a Bugatti. In the line of the Porsche

a little progress The connection with the arms are ready

Photos are added to this topic (with some more information)

He man, that can work, but i used the universal joints for it. But thnx for bringing it up.

A few years ago i started to make an technic Lego Turbo polyp (fun fair ride) Some call it "Kraken" or "Octopus" How it works The Turbo polyp has a rotating cilinder that holds the arms It also has a second cilinder that rotates the opposite direction. This cilinder containes a lifting system that pushes the head upwards The arms are attached to the head. When the head goes up the arms will make a jumping movement. Heres a video of the real thing: The first model main frame (2013) I build this 5 years ago. with normal turntables. Because its containes two turntables on top or eachother and with the size of the model its was way to heavy to work properly. here is a (blurry) picture of that model The second model main frame(2016) So i started to rebuild the whole thing. I had to build a custom turntable. So i used catterpillar parts to make the turntable. The space in the middle had to be clear to build the support of the middle cilinder it turned out great. surpisingly sturdy and can handle a big load. 4 rubber powered wheels handled the rotation of the ring. Here is the underframe (in buildprogress): And here is the new design turntable: It was very sturdy and could manage heavy weight in it Problem was how to make electric connections on this turntable?(rotating or drag contacts) And the lifting mechanism on the second cilinder was to weak. I was frustrated and the project ended on the attic on a shelf The third model main frame(now) A year ago or so i saw that the new digging machine containes the new curved gear racks. So i figured...that can be the sollution of my project. so i took the old model and began to rebuild the drive ring with the new gear racks i began with order a big pile of parts The new yellow rings are great. They can function as ring with a very sturdy structure to support the weight. It has a small ledge where i perfectly can put round tiles (1 stud) to make an great bearing and i can use the racks to make nice the arms with a nice bow (see photo) I dismanteled the underframe to make the new rings fit properly Here are some photos of the project: The new lower drive ringcilinder that holds the arms:(without springs to hold up the weight:)] [ The lower ring containes two seperates rings. first ring for the main rotation, second ring for control the speed of the rotation of the crosses. This gears are connected to the second ring and due to a connection with the armbrackets the crosses will rotate. By make the second ring rotate, the crosses will slow down or speed up The middle part is connected to the main underframe. that holds up the second cilinder with the lift cilinder. So the 2 cilinder are rotating apart from eachother) Lift system Also the lifting system in the second cilinder is competally modified In the first model used 3 actuators for the lifting system but....to weak. btw..it can only lift the length of 5 studs Then pneumatic? to weak. They a scissor lift system..guess what...to weak! Now i have the sollution..a horizontal 11L gear rack driven by a 24 tooth gear by a worm gear. The gearrack pushes the head upwards. The internal structure of this is so strong it is nearly impossible to slip. And it can lift up to 3,5 kilograms Only think i need to take care of is not go further then the end point because it could damage the motor Here the photos of how the lifting system operate A look from underside (the lift structure is hidden, but i will add a LDD picture of it how its works) I added two hard springs in the structure for extra support the lifting New arm design The old arms i made of studded beams with 3 corners in the arm. Problem one: it looked to "lumpy" Problem 2: its was not very sturdy Problem 3: to heavy Problem 4: difficult to add light wiring Soooo....why not rebuild it? so i did.. Now with the curved gearracks on it. it looks better, its is lighter and very sturdy. Also great for adding wiring for the lights. All arms together: (main frames) Arms in the position that will be when finished the model (for expression) The ends of each arm containes a gear with a smal turntable. Perfect for adding a linear electric contact (non Lego), for the wiring and lights. The lights will be Chasing EL wire and it will look awesome. And a photo while building it: To be continued

A nice shot:)
