Fresh hacks every day
Modeling simple objects in 3D can take some time. Modeling complex items… well you can get your college degree in that sort of thing. This method side-steps the artistic skill necessary to make the real virtual by using a laser and camera to map a three-dimensional object.
[Alessandro Grossi] is breaking the rules by using a 100mW laser for … Read the rest
Most of the time we feature hokey film footage in our Retrotechtacular series, but we think this hack is as cool today as it was fifty years ago. [Clint] wrote in to tell us about Operation Red Line. It was an experiment performed May 3rd and 4th, 1963, which means the 50th anniversary just passed a few weeks ago. … Read the rest
[Rich Olson] wrote in to share his technique for making dual-sided printed circuit boards using a laser cutter. Unfortunately this still depends on etching copper clad boards with chemicals. But his process makes it really easy to produce well-defined and precisely aligned etch resist on both sides of the board all at once.
This can be really tough to … Read the rest
Check out the Einstein head which [Sebastian Müller] etched on the cover of his calculator using a laser engraver he made from scratch. We think he did a great job with the build, but we’re even more impressed with the work he put into sharing the techniques he used to salvage and repurpose all the components. It’s a perfect … Read the rest
[Johannes] has been reading Hackaday for years but this is the first project he’s tipped us off about. It’s a laser engraver built from a DVD burner diode (translated). It turned out so well we wonder what other projects he’s forgotten to tip us off about?
This is the second CNC machine he’s seen through from start to … Read the rest
It was time for some new T-shirts so [Andreas Hölldorfer] built a laser cutter. Wait, what? That’s the excuse he’s going with, and in the end this scratch built laser cutter did come in handy by cutting stencils to use when decorating his garments.
The first thing we thought when looking at the cutter is where’s the tube? [Andreas] didn’t … Read the rest
[Wuzabear] wrote in to tell us about this “DIY Laser Cutter for PCB Stencils.” While a full BOM and step-by-step build instructions aren’t provided for the frame, pictures of the build are available, and some different options for construction are discussed. One other option that was especially interesting would be to use a ready-built RepRap or other 3D printer to … Read the rest
