Fresh hacks every day
Members of Sector67 tried their hands at laser cut gingerbread houses. The Madison, Wisconsin based hackerspace is using the tabbed box method of assembly for the corners of the structure. They've also put up a bunch of information about laser settings and published the recipe used to mix up a sheet of gingerbread. This quite a bit more info than was provided with the project we saw a couple of … [Read more...]

[CGPatterson] ended up making this case from a single sheet of transparency film. The project is basically papercraft. He started with the dimensions published on … [Read more...]

[Luca] wrote this four page tutorial to help others, he makes it look really easy, and the sky's the limit on eye candy once you get he basics in place. The first step is to create the dynamic SVG (vector graphic) file using Inkscape … [Read more...]
[Windell] developed an Inkscape extension called Hershey Text that helps you process fonts into vector representations. If you've tried to 3D print, plot, or mill text in the past you may have run across the problem of generating vector paths that deal with the outline and fill of the text appropriately.
