Living At The Close Of The Multiway Era

After over a decade of laptop use, I made the move a couple of months ago back to a desktop computer. An ex-corporate compact PC and a large widescreen monitor on a stand, and alongside them a proper mouse and my trusty IBM Model M that has served me for …read more

From Fail to Wail: Guitar Picks Made from 3D Printed Waste

Between failed prints and iterative designs that need a few attempts before you nail them down, a certain amount of wasted material is essentially unavoidable when 3D printing. The good news is that PLA is a bioplastic and can be broken down via industrial composting, but even still, any method …read more

Automate Sorting Your Trash With Some Healthy Machine Learning

Sorting trash into the right categories is pretty much a daily bother. Who hasn’t stood there in front of the two, three, five or more bins (depending on your area and country), pondering which bin it should go into? [Alvaro Ferrán Cifuentes]’s SeparAItor project is a proof of concept robot …read more

No Filament Needed in this Direct Extrusion 3D-Printer

Ground plastic bits go in one end, finished 3D-prints come out the other. That’s the idea behind [HomoFaciens]’ latest build: a direct-extrusion 3D-printer. And like all of his builds, it’s made from scraps and bits most of us would throw out.

Take the extrusion screw. Like the homemade rotary encoders …read more

Innovative Bird Feeder Design Recycles Recycling’s Garbage

Recycling beverage cartons isn’t 100% efficient. The process yields some unusable garbage as a byproduct. Why? Because containers like juice boxes are mostly paper, but also contain plastic and aluminum. The recycling process recovers the paper fibers for re-use, but what’s left after that is a mixture of plastic rejects …read more

Benchmarking a Garbage Disposal Using The 3DBenchy Tugboat

We’ve always had a love-hate relationship with 3DBenchy, the tugboat-shaped 3D printer calibration target. On one hand, it’s incredibly useful to have a common, widely used, and challenging benchmark object to evaluate printer performance and improve tuning, but we’d somehow like to get back the countless frustrated hours we’ve spent …read more

This Bot Might Be The Way To Save Recycling

Recycling is on paper at least, a wonderful thing. Taking waste and converting it into new usable material is generally more efficient than digging up more raw materials. Unfortunately though, sorting this waste material is a labor-intensive process. With China implementing bans on waste imports, suddenly the world is finding …read more

The Woeful World of Worldwide E-Waste

How large is the cache of discarded electronics in your home? They were once expensive and cherished items, but now they’re a question-mark for responsible disposal. I’m going to dig into this problem — which goes far beyond your collection of dead smartphones — as well as the issues of …read more

Build Your Next Dancing Robot From Empty Soda Bottles

When you think about the materials for your next large dancing robot build, soda bottles might not be the first thing that springs to mind. But they could work, according to TrussFab, a project from a group of students at the Hasso Plattner Instituit. Their system uses empty coke bottles and 3D printed connectors to build large structures, modeled in software that checks their load balance and safety. The team has modeled and built designs up to 5 meters high. Now, the project has taken a step further by adding linear actuators and hinges to the mix so you can …read more

Getting Resourceful to Build A Home CNC

CNC really is a game changer when it comes to machining. If your motor skills or ability to focus aren’t all there, you don’t need to worry – the computer will handle the manual task of machining for you! These builds are popular for DIYers to undertake, as they enable the production of all manner of interesting and advanced parts at home once they’re up and running. However, parts to build a CNC machine can get spendy; [Brenda] decided to take a recycling-based approach to her build instead (Youtube link).

The build uses motion parts from an old silicon wafer …read more
