LEGO Technic Turbo Polyp / Kraken

Incredible! Besides some complex GBC stuff, this is one of my favourite MOCs so far!

That's epic, too bad it took so long, would have been a awesome entry for TC14.

I thought so too.

I can't wait to see the strobe lights in action. I want to blinded by them.

thnx

A little update

here a small video of 1 strobelight. Now this strobe flashes with a second delay, but all 4 strobes flashing together in 1 sequence, (a typical way of connecting)

Building the stage update

The model is now ready to go.

Here a picture of the whole model with the floor, strobelights and a part of the spiderweb background:

@Techniccrack, do you use the same bearing design for the center hub as the 42082 RTC?

Update!

Mechanical programmer

Last few days worked on the programmer.

its a mechanical device with a hub that is going along a slider.

the hub will active different switches.

The program sequence will be:

1. Stagelights on

2. center cilinder start rotate

3. model starting to spin slowly (step 1)

4. model going faster (step 2)

5. lights on model activate

6. lift activation

7. model going slower (step 1)

8. smoke coming through the floor(at the center unit)

9. model going full speed

10. light on model turns off

11. stage lights turns off

12. stroboscope turns on

13.lights on model turns on

13. model going slower (full speed to step 2 to step 1)

14. model comes to complete stop

total running time: about 2,5 minutes

I haven't really checked this forum for a while.

Lovely progress! 1 wishlist, bigger pictures someday?

I had the absolute pleasure to see this monster of a build in real life and in action today! What a supurb machine. The photos on this forum do it no justice. This thing is absolutely massive and looks awesome! Keep up the good work!

I saw it yesterday, although not in action. A giant build!

I saw it this massive fairground attraction last friday too. Not fully completed but is was a beauty to see it in action.

It was great to see that you got after a lot off stress at LW, finale got almost everything working on her.

I hope that you also got a great time at LW and was great to meet you and your fantastic MOC. The small bugs in her is only fine tuning. 

[Techniccrack]

Thnx everyone.

I had a great time on Lego world.

The model is now back to the worktable.

Adding new gears, axles and working on the improvements to make it better. After 3 days spinning i now know what the flaws are.

Nice to see forum members in real life:)

So... how about a few pics or a video of the model from the event for the rest of us?

Coming. .

Update!

Footage from the exhibition LegoWorld,

a great experience, and also a good test for the model.

Afterwards there a a lot of geardust under  the model,the main rotating axles were 20% thinner and the main cilinder suffered from slippery surface, so at the end the model didnt spin great anymore. But a great lesson for the next exhibition.

Here a small video of the Turbo Spider in action on the exhibition.

The mechanical programmer wasnt finished on time.  Also not all the light systems are working (it was also very bright on the exhibition)

The time was killing me to make it all work properly, and a lot things must be done to improve the model.

But enjoy!:

I hope someone with a better video camera took some footage of it.

It is an amazing piece of work, it needs HD video quality :)

Thanks for all the photos as you built it, it has been fascinating watching your progression and problem solving!

I absolutly love this project. Movement appears quite natural. Cant wait to see it in motion with fog and the remaining lights. 

[Shiva]

I agree with the above commenters.

Fog is already there.

I am upgrading the model right now

And i will make video (in hd) with a complete fully operating model.

A little more patience. 

Video is coming soon!

[Techniccrack]

Upgrade update!

First upgrade of the mechanics.

The main drive cilinder suffered from lack of grip. the rubber wheels keep spinning but the model was not moving good enough.

I had the option to replace the rubber band around the cilinder with tracks. but that coaused a problem with the electric copper ring.

So...i have made something myself.

Its not Lego, but the same ABS material. 

I designed a toothed ring exspecially for the cilinder.

A little measuring and digital sculpting to make a the teeth exactly the same size as Lego teeth. Diamater 16,7 cm and laser cutted myself.

So no more slipping rubber.

Turned out great and perfect fit

That is a bit cheaty, but at this point, I don't care, as it is such a good model. Hope it helps with reliability!

Is the dark stuff on the yellow LEGO either rubber or LEGO dust from it being run so much?

I know its a bit cheaty (sry :))

the black stuff is indeed rubber left overs and black geardust

i have to clean it out. The copperband is also weared out and must be replaced

It is amazing how quickly these things deteriorate when run constantly at events.

I guess one issue for you, is some of the weight involved.

May be worth using lubricant at events?

I did use spray to lube the rotationpoint of the head.not the gears

I will look at it for uocoming events
