Though it’s really more apple cider weather here at Hackaday HQ, freshly-squeezed OJ is a treat that knows no season. Sure generates a lot of peel, though. Not something you think about when you’re used to buying it in jugs at the grocery store. What a waste, huh? Italian design firm [Carlo Rotti] teamed up […]
There’s plenty of different methods to build a 3D scanner, with photogrammetry being a particularly accessible way to do it. This involves taking a series of photos from different angles to build up the geometry of the model. If you want to do this with something small, instead of a camera, just substitute a microscope! […]
For humans, life is in the eyes. Same deal with automatons. The more realistic the eyes, the more lifelike (and potentially disturbing) the automaton is. [lkkalebob] knows this. [lkkalebob] is so dedicated to ocular realism in his ultra-real eyeballs that he’s perfected a way to make the minuscule veins from a whisper of cotton thread. […]
There’s something oddly soothing about the practice of laying down Perler Beads on a casual weekend to make your favorite classic Nintendo characters. But seriously, why use our grubby hands like a caveman when we could leverage a machine to do the heavy-lifting for us? That’s exactly what [knezuld11] did! They’ve built a 64-color Bead […]
If you thought CADing designs for 3D printing was hard enough, wait until you hear about this .stl trick. [Angus] of Maker’s Muse recently demoed a method for creating hidden geometries in .stl files that are only revealed during the slicing process before a 3D print. (Video, embedded below.) The process involves creating geometries with […]
The purpose of Geometer becomes apparent when you realize its simplicity: [David Troetschel]’s project is to create an easily understandable design tool that encourages goal-oriented design. The kit comes with physical components and digital counterparts that can be combined in a modular way. They each have a specific geometry, which provide versatility while keeping manufacturing […]
Some 3D printers will give you prints with surfaces resembling salmon skin – not exactly the result you want when you’re looking for a high-quality print job. On bad print jobs, you can usually notice that the surface is shaking – even on the millimeter scale, this is enough to give the print a bumpy […]
While we know some 3D printer operators who need coffee, Washington State University is showing an improved PLA material that incorporates used coffee waste. Regular PLA is not known for being especially strong, though It isn’t uncommon for vendors to add things to their PLA to change its characteristics. The new material containing about 20% […]
What’s more awesome than a normal hexapod robot? What about a MEGA hexapod? Max the Megapod, a six-legged 3D-printed walking robot, is an open source, Arduino-based, Bluetooth controlled, Scratch programmable creation made possible by [Steven Pendergrast]. The design for Max was based on a previous hexapod project, Vorpal the Hexapod, which has since been built […]
This servo/gear reduction was assembled with almost all 3D-printed parts. Apart from a brushed 36 V DC-motor, a stainless steel shaft, and screws for holding the servo together, the only other non-printed part is the BTS7960B motor driver. Some interesting stats about the plastic servo – its stall torque is about 55 kg/cm, reaching a […]
