Collaborate Disseminate
Jokes aside, manually designing linkages that move along specific paths is no easy task. Whether we’re doodling paper sketches or constraining lines in a CAD program, we still need to do the work of actually “imagining” the linkage design. If only there were some sort of tool that would do …read more

We’re pretty familiar with budget resistor-based bend sensors at this point, but this sensor is in a totally different class. Instead of relying on resistive elements, [Useok Jeong] and [Kyu-Jin Cho] devised a bend sensor that relies on geometric properties of the sensor itself. The result is a higher-fidelity measuring …read more

I admit: a few years of prototyping without easy machine shop access really whets my tastebuds for turning metal chips. But all that time spent away from proper machine tools has also pushed me to re-imagine part catalogs, something I see almost every day. Without any precision metalworking tools handy, …read more

Simply having a few go-to 3D printer motion system designs is no reason to stop exploring them, as even small iterations on an existing architecture can yield some tremendous improvements. In the last few months, both [Annex_Engineering] and [wesc23] have been piloting a rail-derived crossed gantry architecture, a “CroXY” as …read more
We might’ve thought that extrusion based 3D printers have hit their peak in performance capabilities. With the remaining process variables being tricky to model and control, there’s only so much we can expect on dimensional accuracy from extruded plastic processes. But what if we mixed machines, adding a second machining …read more

When the first Bantam Tools’ Milling Machine landed, it put PCB prototyping at the forefront with a smooth software and hardware pipeline for spinning out circuit boards in a manner of minutes. Now the folks at Bantam Tools are back, putting those insights into a new machine that makes cutting …read more

Most folks that have been poking around at multi-tool 3D printing know that lining up nozzles can be a gnarly, but necessary pain point. Existing methods either have us measure offsets with a vernier scale or with a series of pictures taken with an upwards-facing camera. And this step is …read more

Last week, [Danal Estes] passed away. This comes as a shock to many of us who had the pleasure of interacting with him online. Not only was [Danal] an active contributor to the 3D printing community, he was simply a warm-hearted character who was just fun to get along with. …read more

With everything from APIs to Raspberry Pis making it even easier for us to create and share objects shaped by personal whim, it’s high time that Don Norman’s sage design advice falls on not just the design student, but the hardware hacker and DIY enthusiast too. Grab yourself a coffee …read more

Laser cutters are certainly a Hackerspace staple for cutting fabrics in some circles. But for the few fabrics derived from non-woven plastics, why not try fusing them together? That’s exactly what [Dries] did, and with some calibration, the result is a speedy means of seaming together two fabrics–no needles necessary! …read more
