Fresh hacks every day

It's the thing in the upper right of the field that looks a bit like a soldering iron. In this case it's being used like a dot matrix printer. We suppose this is a form of halftone printing, although it doesn't produce the uniformity we've seen with … [Read more...]
[Johnie] built himself a CNC woodburner powered by the sun. Like the solar 3D printer we saw last summer, [Johnie]'s build uses a giant Fresnel lens to focus sunlight onto a piece of wood. To get some control out of his build, a 2-axis bed was made from scrounged and junked parts. The lens in [Johnie]'s build looks to be about a foot square - more than hot enough to burn a few holes in things … [Read more...]

The 300 mW unit does a nice job of wood-burning any pattern sent to it, but isn't strong enough to serve as a laser cutter for anything other than thin-film. We wonder if it can be used to cut solder paste stencils for surface mount PCB production. In the video … [Read more...]
