I saw this weight reversal (hidden in a couple of proto's designs) that christian19833 made on fc2

Everybody...
Wait for it...

MECHANICAL CHAMP #2!

http://www.fantasticcontraption.com/?designId=11800404

almost as cool as lord_hamybal's. But not even close. haha

Also the first time I've named a design since June 17th

would this work as a pult if I got it to work?
it would only work in specific situations tho

[Double.S]

would this work as a pult if I got it to work?

I would believe so. lol

retrieval levels, perhaps? Big trick for them if this works. BTW I thought of this retrieval concept during french(in school) and developed it into a catapult during core(also in school). My brain is focused. FYI I'm in grade 6 so my mind can only comprehend designs of limited complexity(I have no idea how the overkill ones work, or those mega extenders and bridges).

Indefinately Stable Contraption?
FC:requires weight
FC2:requires fixed points

but the basic idea is just the triangular prism shape

[jdccdj1]

not sure if this is considered a mech or not, but i am gonna post it anyways...many moons ago, i had a
design where i used 2 trapezoids connected to do some useful work: http://www.fantasticcontraption.com/?designId=11433303
the 2 "O's" in the design are essentially 2 locked trapezoids with no internal bracing, hence they collapse
into themselves...now, as i was perusing some archival designs the other day, i came across a design by babits:
http://www.fantasticcontraption.com/?designId=11228325 a single collapsing trapezoid and it triggered in
my memory the "cool" design i had...so i thot, "what if i put 2 traps together with a drop weight and see what happens"...
well, this is what i came up with: http://www.fantasticcontraption.com/?designId=11849529 ...and this is a tailored
solve using that "mech": http://www.fantasticcontraption.com/?designId=11849530 ...anyway, not sure if it is
considered a mech or not, but at least it is one more useful tool

oh btw, i shamelessly borrowed babit's drop weight idea for this: http://www.fantasticcontraption.com/?designId=11847961
but as you can see, it was "rejected", haha

[gunsjammed2]

^^^ Dat's some CRAZY stuff there. Makes my brain hurt just watching all those designs. Love it.

...and this is a tailored

That is off the charts astonishing imo. haven't seen anything like that since lukasran.

(but i have been snooping around enough to see rianbay is getting darn clever)

[marcxb]

I love a lot mechanical design! This one is a very good one! Took me some replay to figured out how it was working haha!

(but i have been snooping around enough to see rianbay is getting darn clever)

*rianbay812 licks his chops*

great stuff jdc, I'll look around and try to apply it when I stop derping on this game.
(edit: just kidding, I can't figure out how it works lol)

Ya'lls better prepare for the world's ugliest solve I just submitted for the beauty comp

[Error-QM]

What are chops

[jdccdj1]

i appreciate the comments guys...i have been coming up with alot of different variations and
most of them have alot of movement...it seems to me that this concept is just an extension
of babit's floating triangle concept whereas in that one, the floating triangles are mostly tethered
to rigid structures and create alot of movement, and this one the triangle(s) is/are attatched to
unbraced quadrilaterals and rigid structures creating alot of movement...as i come up with more
things that are polished, i will post them... anyway, i can't explain what i think is going on too well,
but i can sure as heck make sense of it in my own head, haha....

this is old, but, i have also been working on ideas where the floating triangle is attatched to structures
that float as well, but not like the quadrilateral floating...better put, they move in relation to the floating triangle like in an arc...
all the complex mech designs have some part in them that have something like this...

i say if you are bored with the same old things going on in designs, explore some of the master contraptioneer's
archives...you'd be surprised at the ideas you can come up with or things you can improve upon by watching high
quality designs

Brace yourselves for a really long post

So I'm exploring the possibilities of adding more shapes to our knowledge base. So far we only have 2 (triangle and quadrilateral). We obviously haven't even scratched the surface of exploring all of the possibilities for a quadrilateral, seeing as we've spent years stuck on the idea. For good reason though, as they've given us this thingy, this thingy, and my personal favorite, this thingy!
Quadrilaterals are good for more motions and more flexibility right? And in the case of my rianmech thingy, it allows for the re-use/reduction of weight.

So why not add another side?

It actually isn't that difficult if you think about it, the trouble is controlling it and being able to apply it. Things start getting a little flimsy.
So an idea I came up with is this pentagon: http://www.fantasticcontraption.com/?designId=11850810
I can't show you the design I used it for because it's a competition solve, but you can see it has many different motions. Basically anything that moves can be attached to a lever to make it move. For example, [1], [2], [3].

There are other ways of using pentagons if you can control them. This, for example, http://www.fantasticcontraption.com/?designId=11850829 utilizes 3 motions as well, and any moving joint can be connected to a lever. I like this example because it can lay out a scene as it falls, then do something else while totally unaffecting the original result. And should the unstable-ness bother you, you can always add chains and rianmechs to make it behave like you want. Anyway, that's my input on thie idea.


On a completely different note, I also realized moments ago that my design http://www.fantasticcontraption.com/?designId=11838845 works under jdc's discovery, in that two quadrilaterals are working together to achieve something weird.

That is like totally inunderstandable (is it a real word?) thing I've seen in a while

Perhaps you mean derstandable?

Give it a sec...

[jdccdj1]

excellent work rianbay!...

getting curious to see your comp design now

[Pawel.]

This is not a mech but i don't want to start a new thread so:
I just made this design: http://www.fantasticcontraption.com/?designId=11856116
After it wins it slides out of the goal area but then it starts to go up for some reason?
Anybody knows why?

[ScienceGuy2012]

Pawel got a derp:most likely from the ball straining causing small bits of movement, and creating that
hope you understood that

Previous topic: So you aren't female.
Kind of off topic but as pawel said, not making a new thread or anything

[ken75]

I've been working with wheels a lot lately and I came up with this mech that's useful in a lot of different ways. I think it's really useful for levels with small build areas.
