Someone’s hooked up a game controller to wirelessy contol a CNC machine… which I guess means that you could do the same thing with waving-arms-around-interface, kinect.

I’d never seen a CNC mill before – I was expecting something the size of a potato-chip vending machine… that looks like this

which IS actually a CNC mill for sale in NZ for like $120,000.

That’s big and scary. I don’t want big and scary – I want something smaller than I am. Like this isn’t.

Controlled by Arduino, with tutorial etc on the site.

A slightly more together looking variant here:

Machine generations.

Something I’m noticing myself now that I’m getting away (hah) from programming and more into physical stuff… the prototype is generally corrugated cardboard, wood, hacked-acrylic… what the likes of Ponoko do is reduce the gulf between “hacked proof-of-concept” to “work of art” to…

…, an evening in front of a graphics program.

What Ponoko do is reduce massively reduce the energy that is required for the Second Machine Generation.

What I’d really love for them to be able to do (do you hear this Ponoko folk?) is a same-day turnaround.

I can remember when mail-order had a standard 28 day delivery time, then Amazon was invented and destroyed that model… in the UK I’ve ordered a book from Amazon and had it in my mailbox the next morning. Ebay took up this approach, and now we kindof expect more or less instant delivery. This would be really useful for Ponoko to be able to do, because there’s an experiment-cycle. Try->fail, try->fail, try->fail, try->succeed. This can take months.

So um… the core-value that I’m getting from Ponoko is the massive attenuation of the Concept->Art process. If they want to improve their service (to Me me me) then a big thing they could do is figure a way to radically lower the turnaround time.

But I don’t know their business, or what’s involved, or if this is a reasonable thing to suggest etc… If I were to buy my own laser-cutter though, that’s the reason I’d do it. To reduce the Concept->Art process. That’s what this stuff is for. De-Sublimation.

Anyway, back to the CNC…

These are starting to show up around the place quite a bit… eg: buildyourcnc.com, but nothing quite as cheap as the one above.

Here’s a variant that uses strings instead of rails

from ponoko

Which makes the maths a whole lot scarier, and I have a feeling that there may be fairly serious issues with precision… but it’s an interesting idea nonetheless.

It might be interesting to try a variation where the motors (which when on the corners will need to be synched, which could be tricky) aren’t at the corners, but are actually in the machine itself, which just uses the corners as a reference point. You wouldn’t need as many of them then.

A bit like the CNC router robot from last year… which impressed everyone then kindof disappeared… which was a pity. I was expecting to see a whole wave of them after that.

I mean that thing is really cool.
