## Leaked contraptioneering secret #1: Floating triangles

### Leaked contraptioneering secret #1: Floating triangles

Tired of that old brown pult and boring arm?
How about using some of these nifty techniques to spunk up your design?
I will show you how to waste that extra 30 minutes solving that easy 5 minute level you found.
Keep in mind the finished product will be awesome.

Remember, I'm not the best at explaining stuff like this.
Most of the stuff I make uses bases that have 360 degrees of rotation. 180 for extension and 180 for contraction.
You need to keep in mind most are different than that one, and while almost all use 360 degrees of rotation, they don't usually rotate in one direction for long.

Luckily, this one will for easy learning.
Use that extra motion to convert rotational energy to linear, sort of like a cam: http://www.fantasticcontraption.com/?designId=11597807 you can also use reversal,
Kind of like this: http://www.fantasticcontraption.com/?designId=11597810 the main moving triangle only travels 180 degrees in a direction and then reverses.
Although its nice to have that full circle rotation, this is generally what will happen once you build on a structure like this. They like to wobble around.
So lets add some stuff to that cam up there: http://www.fantasticcontraption.com/?designId=11597858 if you're contraption savvy, you can make any kind of path.

Just one of many ways to make 360 degrees of motion is shown here. Another way to use floating triangles: http://www.fantasticcontraption.com/?designId=11597834
You can see clearly the parallelo-arms work great here.
Oh, one last thing, http://www.fantasticcontraption.com/?designId=11597865 the more joints you have in your base, the more possibilities you can create.

My idea was to create base mechanisms with excess rotation and use all of it. Tweak this and try adding new parts and mechanisms until you get the hang of it.
Eventually, you will be able to make your own overly complex designs.
:p

here was a pm i sent to lukasran when i was just figuring out these arms. lolz nostalgia..and probably a better tutorial than what i just gave >.> but with more old school mechanisms.
Aug 09, 2010 (lol)

Workin' with the new stuff

here is whats been happening. i changed the way the weight effects the structures of triangles and parallelograms. basically instead of connecting it to a solid structure its flimsy. but they can move freely and aren't slaves to any particular movement. so when you add other flimsy structures to them you can change the way they originally worked and make something totally new.

for instance:
A regular design- http://fantasticcontraption.com/?designId=11025227
when a rod is added to a point- http://fantasticcontraption.com/?designId=11025276 it goes nowhere, so i decided to fix that
I created "floating" triangles.
http://fantasticcontraption.com/?designId=11025236
when a rod is added to a point- http://fantasticcontraption.com/?designId=11025240 a totally new motion is created- opening a new venue in FC :D
and you can add other floating stuff to it and get more new motions- http://fantasticcontraption.com/?designId=11025261

basically if you really think carefully you an make any motion(s) you want.

cool ones:
http://fantasticcontraption.com/?designId=11015060 (don't take yet i'm still working with it)
http://fantasticcontraption.com/?designId=11025288 (gave up on this need help lukas! )

some are better and more fun to watch than others- you can make parallelograms float too. thoose look cool- and of course you can mix the two.
..hope you can make some stunning designs. don't let this leak out yet i would like to keep it secret for a bit longer
but i will eventually make a guide....maybe.. if the forums start to die again :P

best regards,

Wow, nice on the floating triangle stuff. That's like thik's theory of making insecure attachments taken to a whoooooole new level.

thanks rianbay

lol that was a while ago but thats the BIG secret, there are a few smaller ones too..but a can't seem to explain them well.
Floating triangles have no solid base directly attached, which is why they can move around so weirdly. aaannnnnd...they really don't need 360 degrees rotational mechanisms as a base but its much easier to manipulate. (at least for me.)

This is awesome, thanks for showing this

I tried making some contraptions using the floating triangle, but I always have trouble with it getting stuck/not rotating all the way.. Sometimes it does about 180 degrees then turns around :P I guess I just need to practice it some more

Edit: Well I did pretty much copy one of your examples, but I got it working in a design.. Thanks man, and nice job.

Nice uiop! lol feel like a jerk for not giving away the secrets but sort of wanted to keep it from being the new trend where everyone is making the same thing...also i just wanted to be a n00b and show off for a while

not rotating all the way? as long as it turns around its good. that's usually what happens to me i just roll with it lol..usually it turns out better. i just figured it would be easier to show it the 360 way. most of mine don't go in a full circle lol. just finish off the design and see what happens, if it changes the way the device moves, add pieces accordingly to make a new way to get to the ball..think through it man!

I've been attempting this for a few hours and I still can't do it

That's funny, I always thought of these in terms of the quadrilaterals formed by the rods connecting to the "floating triangles". The triangles were an afterthought to me (to get crazier and more useful motion).

This is my new project... now that we have livestream up though, could someone possibly do a livestream of a simple retrieve? Id appreciate it because it'd make things easier for me.
