Awesome!! However, I couldn't help notice that if you have a 3D object, it seems that it keeps spinning the chord around the machine - at one point it would unplug itself - should be an easy fix though.

Wow nice prototype, does it make sense to use Arduino production?

adestefan• 14 years ago

Absolutely not as it would be too expensive. It looks like the Arduino is used to drive a couple motors. You could do the same thing with any inexpensive micro-controller. It's a pretty cool, self contained design though.

If you have code for an Arudino, you can make a board that uses an AVR microcontroller (made by Atmel[0]) with that same code. It may be possible to use a cheaper AVR if you don't need the same functionality (eg, if you aren't using hardware pulse width modulation, there are cheaper chips) with only slight code modifications.

This is great! Very ingenious design. How would it fare with thin wire?

So cool -- out of curiosity, is this emulating the actions of a pre-existing, "professional" machine or is the concept brand new?

There are wire and pipe bending machines that do this on a larger (and probably smaller) scale. They are however expensive and I doubt their tool chain is open source

neonkiwi2• 14 years ago

There are expensive machines you can buy that do this: CNC wire benders. From the first page of YouTube hits: http://www.youtube.com/watch?v=mwygMdpQ8SU

Cool, thanks. I just noticed they allude to these machines in their blog post: http://blog.pensanyc.com/tagged/DIWire

Is there a 3d LOGO?

gravitronic• 14 years ago

Not sure if you mean purely software, but generally CNC machines are instructed in a language called G-Code which is basically 3D LOGO (move absolute/relative on a number of axis and some extra instructions to start/stop spindle, etc)

iliis• 14 years ago

At least xlogo supports 3D (http://xlogo.tuxfamily.org/).

it will be hours of fun

somebody should create a online shop where we can get these gadgets built and shipped

oellegaard2• 14 years ago

Yeah, that'd be awesome! Or at least make some IKEA-like instructions on how to assemble them - as a programmer I have no idea how to put these things together. I would totally pay for that, like an arduino device, packed IKEA style.

How does it know how not to bend the wire so it doesn't interfere with its own operation? And if it doesn't know, are there are set of heuristics used to know when the design you make isn't possible?

I was waiting to see exactly how this was handled on the octothorpe, but he strategically cut it short. Also, it seemed a little hand-wavy placing a simple spring among a collection of far more complex 3d objects.

It's an awesome project, but I appreciate when engineers either show how they addressed the edge cases, or are more honest about its failure points.

jonnycowboy• 14 years ago

The more modern CAM packages will do this for you automatically (routing CNC so that it does not interfere with the part) but this version probably relies on the user to properly define the bends and angles so that no interference occurs.

Here is a youtube video of same: http://www.youtube.com/watch?v=ve1zzDXlJoA

(For some reason Firefox + linux doesn't like Vimeo most of the time)

This is a cool device. And wire bending is used in a lot of things, from making holders to support frames. These things tend to be tuned to a particular wire gauge and minimum radius so some tool and die shops will have either multiple benders or various dies for a configurable bender.

Cool things you can make with these are baskets for catching/holding parts, springs, latch returns, awesome bubble wands, and artistic lettering.
