Arduino Laser Engraver I started this project because I wanted to make something that had mechanical, electrical and software components. After looking around on Instructables, I figured that an Arduino based laser engraver would be an interesting machine to make, and that the machine itself could make interesting things. Laser diodes have also advanced quite a lot in the last few years, allowing reasonably powerful DIY laser engravers to be made without the hassles of laser tubes. This machine can engrave wood and cut paper. I haven't tried other materials yet because there is no fume extraction capability - plastics generally create toxic gases when burnt. SAFETY WARNING - Please be safe when using lasers.
View topic - The Tiger Explained Here's another fun idea:7D is the lowest dimension where you can have toratopes with 3D cuts that are empty in all 4 cardinal cut directions. An example can be the tiger tritorus (((((II)(II))I)I)I) and its cut ((((()())I)I)I).Now, all nonempty cuts have to be outside the cardinal directions, which means that the diagonal cuts should be still nonempty and interesting Well, that is interesting! I spent some time imagining a 5D intercept array, and how to explore it.
Arduino 3-axis Mini Lazer Paper-Cutter Updated : 16/3 Add step 4, about using the stage. Updated : 18/3 Add photos (cutting vinyl adhesive sheet) Updated : 19/3 Add step 5, acting as pen plotter Updated : 20/3 Add laser engraving video (Wood) and photo Updated : 22/3 Add 2 drawings to show the structures of machine, also visit this link. +++++++++++++++++++ I read many posts and now I had finished my first mini Lazer Cutter. The design is simple and reliable ( u can see the video ) It is using Arduino Duemilanove + GRBL (0.8c) + 100mW blue/ violet lazer with external battery power supply (5V)
Open Source Wedding Rings [update 1][update 2] I lost my wife’s wedding band a few years ago. She handed it to me while I was driving and asked me to take it to a jeweler to get it hammered back “in round”. Of course, I lost it immediately. My original wedding band I still have, but it’s always been a little unsatisfying. My ring finger is thinner than hers, and the pattern never quite matched where the original jeweler sized it down. Maker Faire is the best website I've found about makers, if you want to be one, this is your page! With the launch of MAKE Magazine in 2005, Dougherty and his team provided the catalyst for a tech-influenced DIY community that has come to be identified as the Maker Movement. As the movement has gathered increasing momentum, makers have created their own market ecosystem, developing new products and services. The combination of ingenious makers and innovative technologies such as the Arduino microcontroller and personal 3D printing are driving innovation in manufacturing, engineering, industrial design, hardware technology and education. Over the years, the MAKE division has become synonymous with the Maker Movement and is the recognized leader of this growing community of makers. Many makers are hobbyists, enthusiasts or students (amateurs!)
Full Tilt: 3D Printing Sparks Pinball Revolution Flip. Flip. Clang. Tilt. Print? Circles, Spirals and Sunflowers A Processing.js tutorial by Jim Bumgardner In this tutorial, my aim is to show you some fun ways to draw circles, and spirals, and ultimately, how to draw the interesting pattern you see on sunflowers. All these techniques are described from a few basic facts about circles, which you probably learned (and forgot) a long time ago. Back in grade school, you may have learned these three equations: D (diameter) = 2 R Build Your Own Beautiful Flat-Pack Chair I built this Eames-like chair without touching a single traditional woodworking tool. No, it's not because I'm some kind of Luddite. I just love the immediacy of rendering a chair with 3D modeling software and then cutting out the parts with a CNC machine.
Mazzo di Fiori & the Next Generation 3D Printer by Joshua Harker I am an artist. I have become known for my pioneering work in the 3D printed medium & have a professional history in product invention/design & development. My art is about pushing the limits of form... an exploration into what can be made & how to accomplish it. My venture into this project is a direct extension of that. For the last 18 months I've been developing a new 3D printing technology to usher in the next generation of the 3D printing revolution in terms of quality, capability, cost, access, & ease of use. Double Rainbow All The Way A Processing.js tutorial by Jim Bumgardner In this tutorial, we're going to make an animated double rainbow in Processing.js. I'm doing this to teach you about the HSB color space, and to show you a more sophisticated way of using it. There is also a version of this tutorial which has the same examples in HTML5/Canvas. If you compare both tutorials, you'll find that some aspects of this (especially the color manipulatoin) are easier in Processing. We'll start by making a rectangular bar, which is colored like a rainbow.
Easy CNC conversion of a small mill Why not a 3D printer? I think a lot more people have 3D printers than CNC mills and they're great tools. There's a bit of an overlap with a mill, but they both have their strengths and weaknesses. Students turn to 3D printing to create custom flexible resin skins for prosthetics May 8, 2015 | By Simon It’s no secret that among the many possibilities that additive manufacturing offers is the ability to produce low cost and customized 3D printed prosthetics - oftentimes with futuristic aesthetics that would otherwise be impossible to produce using traditional manufacturing techniques. Whether the prosthetics are for our four-legged friends, war veterans or children who were born with deformities, the use of 3D printing to help others have full functionality of their limbs has been one of the premiere feel-good stories that has come out of 3D printing since it hit the mainstream within the past few years. Now, a group of design and architecture students have taken that “customization factor” a step further and have been busy developing 3D printed prosthetic skins that allow a prosthesis wearer to instantly change the aesthetic of their prosthetic without the need to have multiple prosthetic devices. 3D printed flexible resin
Spreading points on a disc and on a sphere When working with computer graphics, machine vision or simulations of various kind, two problems (among many others) which keep popping out are How to have N points approximately evenly distributed over a discHow to have N points approximately evenly distributed over a sphere One way to build a solution for those two problems is to rely on a particle system. Each point is a particle, particles are repulsing each other with a force. Put the particles on the disc or the sphere surface, at random locations. Shake vigorously the particles, add some small drag force, let the particles reach a steady state, shake again ... rinse, repeat.
