GBC General Discussion

[Ankoku]

Found a new Japanese GBCer

Nothing ground breaking, but that said, no copies either.

[Ankoku]

A nice unique design!

 Also a good way to reuse those ball joint pieces if they cracked instead of throwing them out.

Here's a couple of videos of my latest GBCs.

The Bucket Scoop one is 90% made from parts in the Bucket Wheel Excavator.

I really like the red & black rotating arm on this (You can see it on the right in the preview image):

 

[Frequenzberater]

This is indeed great! I suppose its very challenging in terms of timing.

[Great Ball Pit]

That's a pretty cool self contained circuit!

[Ankoku]

Although I am not that bothered about Mindstorms in relation to GBC (I just like the idea of everything being done of one motor), I have to say, the way this manipulates the grabber really is cool. Also like how it is precise enough to pick up the balls.

except at 1:13 where it fumbles a dropoff!! :D

very nice version of 'fast ball sorter'...  and same.. as much as I like 1-motor-mechanical solutions..   when someone does a mindstorms module that perfoms a *really* neat trick, I'll always be impressed!

The two balls near the grab point suggests it may have failed a few times there too.

I hadn't noticed to be honest.

Very proud, LEGO Technic made a video of my Ball Counter and featured it on FB
Good promotion for GBC I hope.

your link just goes back to here!

[Berthil]

@RohanBeckett, thanks, fixed the link  and also made a screenshot to capture the moment :)

ohh.. at 30seconds, I see a ball dropped!!!   ;)

[Berthil]

Well noticed, I didn't see it :)
It runs great though, no problems in three days running at an event. I have put the 'display' meanwhile 45 degrees up so it's more natural to look at at that angle when standing in front of it.

It totally missed Brothers Bricks had a nice article on it, my apologies to them.

[RohanBeckett]

I have built Nico71/David Manleys one.. but found the input unreliable.. so will redo it one of these days

Was thinking of using a stepper, that guarantees 1 ball at a time, to feed onto the conveyor... rather than a 'tumbler-style' conveyor, that can occasionally bring 2 balls up

 

I do like your numbers setup.. although a lot more brick-intensive than their design!

 

[Ankoku]

I wish LEGO supported GBC more with access to balls.

[Ankoku]

This is nice, I like the motion of the tipping cups:

Nice one! I really like the overflow elements of that machine.

It is a very polished machine, image wise, even though it seems it isn't 100% reliable.

Thanks for videoing it @Maico!

(I try not to post stuff on here when I know said video is done by an active member on here.)

[Maico]

@Ankoku, Thanks.

Never crossed my mind...

[Ankoku]

I really like the speed of this. It is slow enough that you can enjoy watching the ball going round the loop.

haha.. thanks for the post!  still only a work-in-progress.. it needs to have it's own ball input.

I'm almost thinking of having something that feeds balls in pairs.. as two balls going around looks pretty cool!

[Ankoku]

Some interesting designs:
