Phi Calipers : Calipers With Scale

New Caliper design:

scale_1For a while now (eg, about 2 years) it’s bugged me that the calipers I make can only measure down to a certain size – rather than all the way down to zero. I made hundreds of designs… nothing worked terribly well… but eventually a design turned up which caused the complexity to shrink (which is a good sign)… going from 5 parts to 2.

scale_4Complexity reasserted itself in the shape of a scale and case…

scale_9I generated the scales (both inches/mm) by writing a PHP script that generates SVG (zipped script here)… SVG can be imported straight into Inkscape… tweaked, then into the laser-cutter – which can also etch, using Cermark spray.

Cermark Spray is fairly crazy stuff – costs about $150 a can – a type of muddy water-based paint, but when it’s lasered, it winds up being harder than burnt-on rice. It is actually harder than the steel that it’s fused to.

The two parts are held together with a brass binder-screw… which can be tightened, and which allows the pieces to be separated if you want to change from millimetres to inches.

processThe design process looked like this:

but really, the nautilus calipers, and the 5-piece Star-Calipers were all leading to this design.

So hopefully people like them :) – available in the shop under “cool and unusual

Why The Golden Ratio Works For Flowers

Fairly amazing video going into the maths of why flowers (and pine-cones, relative leaf positions etc) are so often based fibonacci numbers. And it's fairly amazing because I actually understood it.

New Product Videos

I'm putting together a series of product videos... one for each of the 10 or so different calipers that I make.

Because they'll all look kindof the same, I've made a separate youtube channel so subscribers don't lose their minds with boredom.…

Golden Ratio Poster

I've been tinkering with movies etc today, and (while I was waiting for things to render) played about with one of the stills and made a poster. I don't know if I'll ever turn it into an actual poster. If anyone is interested though - let me know how big you want it, and I'll do some costings etc. Alternatively,…
