[Patrick Fenner] realised that a bit of mathematical modelling could lead to better designed hinges. This could mean fewer rounds of trial-and-error prototype tests, which would reduce the cost of using lattice hinges in a project, and better fatigue resistance, meaning the hinges could be used for moving parts instead of just for static bends.
BotQueue is an online platform for distributing print jobs to multiple 3D printers for production. As the name suggests, it allows you to create a print queue which contains jobs. Your connected bots will grab jobs and produce them. As each job is competed, the operator is prompted to remove and verify the output. Upon successful completion, the bot will grab the next job and start producing it. This continues until the queue is empty. If a bot fails, it is taken offline for repairs.
There is a fantastic series of posts from Alex over at the ProtoParadigm blog featuring practical things you can do with a 3D printer. This isn’t about wowing people with the latest high-tech advances. It’s all about getting down to the nitty gritty and using that 3D printing versatility to get things done.
So let’s get practical with our printers and extend the function of those ubiquitous glass jars. Documenting each solution with a brief but informative summary, Alex kicks things off himself with some easy-to-open, watertight lids. He then turns to Thingiverse for inspiration, and follows through with bank lids, a fly trap, a sprouting lid for growing seeds, straining and shaking lids, and even a fermentation lid that allows for exchange of gases.
Further exploration on Thingiverse will uncover an even greater diversity of canning jar accessories, from sippy cups to funnels and more. Check them out, and build some of your own!
It’s alive! The Briefcase Printer revisited and heading to Kickstarter
It’s hard to go far in the DIY gadget world without hearing about the exploits of modder extraordinaire, Ben Heck. Famous for squeezing almost every electronic device imaginable into a briefcase, his latest efforts revisit a project to build a fully operational Briefcase 3D printer.
An earlier attempt did have its successes, but Ben always knew he could go further with this particular project. And now he has.
The Briefcase Printer folds out from a neat 4.2 x 18 x 14 inch frame, and boasts a 200mm2 build platform. It’s able to run autonomously by reading files off an SD card, or for more control and a smoother user experience, the onboard Arduino 2580 Mega can be connected directly to a computer.
Give your single speed bike a boost with some parametric goodness
If there was an award for parametric design that made riding your single speed or fixie bike usable on gradients greater than 5 degrees for people other than Olympic athletes, then Jason DeRose would surely take it out with his variable ratio mechanical gear design.
DeRose, a software developer used Python and employed mathematics and geometry to work out the position of the sprocket teeth to craft his design. As part of DeRose’s design process, he then extruded the linework into 3D in Blender. He has also released the project files as open source on launchpad to allow others to build upon it. (more…)
This is another one of those projects that makes me think “who cares what it does, it looks awesome and I want one.” In this case it turns out to be far awesomer than I could have imagined: it’s an $85 DIY Arduino-powered DNA-sequencing device. Complete with comprehensive build instructions so you too can sequence your own genome. Amazing!
This is the first 3D printer I’d consider worthy of Ian Fleming’s Q character in the world of 007. The FoldaRap is a derivative of the RepRap project, the first to be a truely portable 3D printer. It is designed to fit within a tough travelling case. (more…)
We’ve seen Mutable Instruments before around here before: there were a wealth of laser-cut Shruti-1 enclosures rolling out the Personal Factory gates about 18 months ago. It will be great to see what cool designs people come up with to house this new machine!
Arduino has arguably done more to change the DIY electronic landscape than any other open source device. We’ve often encountered this modular hardware wonder, popping up as an integral component in many 3D printers as well as being at the core of some of our favourite DIY projects.
In the trademark affable manner that he is famous for, Arduino co-founder Massimo Banzi talks through the ever-widening scope of this versatile system.
“(Arduino is) …the equivalent of sketching on paper, done with electronics”
From the humble beginnings in an Italian cafe to an incredible diversity of projects being run by all kinds of hackers, makers, enthusiasts and professionals… whether it’s the pre-teen kids tinkering in their bedrooms, high-school students sending satellites into orbit or multi-million dollar global corporations pushing the boundaries of scientific discoveries; Arduino can be found at the heart of a new revolution.
Watch this neat 15 minute TED talk overview from Massimo Banzi, on Arduino’s role in the new paradigm of Open Source Imagination.
