Jeroen Ottens Posted January 15, 2018 Posted January 15, 2018 Very interesting build so far. Looking forward to see it in action. Those quartercircles are ideal for the arms , but I don't know yet whether I am sold on all the system and the few 3rd party parts... But I'll hold my horses until I see the final product. Quote
Techniccrack Posted January 16, 2018 Author Posted January 16, 2018 I made a video of how the rotating system operate. Pure a first stage test of rotation, lift and strength. Enjoy! Quote
Frequenzberater Posted January 17, 2018 Posted January 17, 2018 I must admit, that besides the whole GBC topic, this project is my favorite on EB. Great work so far! Quote
Techniccrack Posted January 18, 2018 Author Posted January 18, 2018 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! Quote
TechnicRCRacer Posted January 19, 2018 Posted January 19, 2018 One of the most awe-inspiring creations I have ever seen! So many functions! This would be the best display model at a convention! Quote
Frequenzberater Posted January 19, 2018 Posted January 19, 2018 Really lifelike movement! Did I already mentioned, that I love this project? Quote
wimpie3 Posted January 19, 2018 Posted January 19, 2018 Impressive! I do have the impression the motors are moving a bit too fast and they stop a bit too sudden... probably that will still be fixed? I do think you'll have a problem with the middle structure though. In the real model, there is a diamond shaped structure (de "ton"), I fear your structure is too thick in the middle to replicate this, right? Quote
Carsten Svendsen Posted January 19, 2018 Posted January 19, 2018 Wow that is so cool, I didn't think it would be that easy to replicate that kind of motion in LEGO. I was proven wrong Quote

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) 19 minutes ago, Carsten Svendsen said: Wow that is so cool, I didn't think it would be that easy to replicate that kind of motion in LEGO. I was proven wrong 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 Edited January 19, 2018 by Techniccrack Quote
wimpie3 Posted January 19, 2018 Posted January 19, 2018 How are you going to make the big ball on top and the accordion underneath? Quote

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 Edited January 19, 2018 by Techniccrack Quote
Frequenzberater Posted January 19, 2018 Posted January 19, 2018 Perhaps you can consider to implement some kind of a flywheel in order to smoothen the movement and avoid sudden starts/stops. Quote

Iam sure that that will be fixed, bro :), there are several ways to do it Quote
Techniccrack Posted January 23, 2018 Author Posted January 23, 2018 a little update. building the crosses on the arms Quote
emielroumen Posted January 24, 2018 Posted January 24, 2018 Very fluid movement, especially during lifting! Interesting to see the progression and hope you are going to post more photos of the inner workings. Quote
Frequenzberater Posted January 24, 2018 Posted January 24, 2018 Provided you can finish this one successfull, are there any plans for building another fair rides in the future? Quote
Techniccrack Posted January 24, 2018 Author Posted January 24, 2018 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 Quote
Frequenzberater Posted January 24, 2018 Posted January 24, 2018 (edited) Thats exactly what I wanted to hear :D In which city does the exhibition takes place? I live in Germany close to the border to the Netherlands. Perhaps there is a chance for me to visit it. Edited January 24, 2018 by Frequenzberater Quote
Techniccrack Posted January 30, 2018 Author Posted January 30, 2018 (edited) A lttle update. building the crosses for the seats: Design of the head: Because my polyp its main color is yellw, i think the best color for the octopus on top is also yellow. It fits with the rest of the machine Head will be 13 studs wide to be continued.. Edited January 30, 2018 by Techniccrack Quote
Techniccrack Posted February 2, 2018 Author Posted February 2, 2018 (edited) A little update. tomorrow i will build the seats. received the parts for it today. Ive made a design of the base of the seats and put some lightwire on it. I only have to decide witch color lightwire i will use Head progress Iam building the head at the moment, but i am missing a few parts.the yellow parts on top must be blue :), and i am missing some connector parts. those will be in the mail today (i hope) to be continued... Edited February 2, 2018 by Techniccrack Quote
Frequenzberater Posted February 2, 2018 Posted February 2, 2018 Amazing! I prefer the blue ones. Quote
Techniccrack Posted February 3, 2018 Author Posted February 3, 2018 (edited) Ive made my disission. it will be orange little update: Building the seats....repeatbuilding...pff Homer and grandpa are enjoying themselves...(not scale correct but i thought it was nice) Progression of the head: to be continued Edited February 3, 2018 by Techniccrack Quote
