  1. 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
  2. This is my version of the "Capstan Hammer" of the Flying Dutchman (cf. https://www.youtube.com/watch?v=9gp73EZdObM) if you want to see the mechanism in action visit https://imgur.com/a/g2uad because I cannot upload more than 0,1 MB :/ The most challenging part was to construct the inner part in such a way that it rotates along with it, but can also be lifted and falls down abruptly. In addition, the mechanism should be kept so small that it can be installed in a normally dimensioned ship. Although the rotary movement of the hammer during lifting is not exactly the same speed as that of the capstan, I am still quite satisfied with the result.

    Ahoi! Inspired by some old paintings, I have built a sailing ship that is attacked by a sea creature. Here are more shots of the ship: I hope you like it! Best Jonas

The Jade Piranha Strikes Again! The Parched Pirate Pirate Pet Shop Warped Wood The Captain's Dinner Death Before Dinner FYI: this entry is pro-Mardier. While many Sea Rats had hired their services out to Mardier in their war against Eslandola, the faction as a whole remained swayed by dubloons, not politics. One such crew had been hired by one Sir Blake, an Eslandolian entrepreneur with grand designs for controlling the seas most feared beasts. He had the ship set sail for open waters, many leagues from the nearest island. Sir Blake had studied the effects of music upon animals and was convinced that he could summon and control a fearsome creature from the depths of the ocean the likes of which had only before been seen in nightmares. He began to play the organ and waited while the reverberations sank deep into the sea. After some time of playing he heard the cry go out "Sea beast spotted captain!" He rushed on deck and boasted proudly, "Now we shall watch as the beast attacks Eslandola's foes!" However, his boast was empty. Rather than command this creature, all Sir Blake had done was awaken and anger it. Following the source of the disturbance, the kraken proceeded to destroy the nuisance. Stunned by his failure, all Sir Blake could do was watch in terror as the crew hopeless tried to fight off the beast.
  5. My entry to Round 4 of The Tourney. The category assigned to me, was, Nightmare: Portray a dark representation of a character's worst nightmares. This nightmare must not be merely reliant on a story to describe it (although you may include one if you wish); the MOC should be easily recognizable as a nightmarish scene. I decided on doing an all LEGO scene, and tried to capture a dark and scary atmosphere with the color choices, landscape, night background and monstrous creatures. The backdrop was inspired by LL, whose builds you should definitely check out: Link More pictures here: Link C&C welcome

    [HSH] Cat A - Steampunk Kraken

    Hello there I had some dark weeks without that much building, but the Home Sweet Home-Contest gave me motivation to build again. There are several cool Lego-Space themes, but i took the chance to build once again in one of my favorite Sci-Fi-worlds: Steampunk! "Every style-conscious Gentleman needs his home. Some have mansions at the sea. But why living at the sea when you can live in the sea?" -Sir Octavius- This is the home of the steamy gentleman Sir Octavius and the scene stands on a round base. The base is not nearly 48 studs in diameter, but i wanted to have space to play with the tentacles overlapping the border of this circle. All photos on MOCpages. Stay creative and steamy! *toof* *toof* Jonas
