EAGLE users have long asked for a simple 3D export that would allow them to cross their designs from the electrical realm into the mechanical realm. The current crop of solutions have suffered from either limited applicability or generated a format that wasn’t widely accepted among mechanical CAD tools. The purpose of this blog post is to inform users of a new tool that can finally fulfill this long requested need.

CadSoft has partnered with SimplifiedSolutions Inc. to create the IDF-to-3D tool.

Flash storage technology will soon see a three-fold improvement in data density thanks to a joint development at Intel and Micron that will allow the production of 3.5 TB flash sticks and 10 TB standard-sized SSDs. Meanwhile, a new 48-layer cell technology development by Toshiba could pave the way for higher write speeds, more reliability and lower costs in solid state drives.

As if smartphones can’t already do enough, soon they may be able to scan three-dimensional objects and send the resultant high-resolution 3D images to a 3D printer that produces hyper-accurate replicas. This comes thanks to a small and inexpensive device called a nanophotonic coherent imager (NCI), which was developed by scientists at Caltech. The NCI could add 3D imaging to a variety of other devices and applications such as improving motion sensitivity in human machine interfaces and driverless cars.

Welcome to this project. The CNC UNO is a small desktop CNC Mill that can be used for hobby engraving and routing, PCB milling and education. It is mainly made with 3D Printed ABS plastic parts and plywood. Before starting this project, please observe that this machine is not intended for precision work nor for cutting hard materials like metal. As the machine parts are made of plastic and wood, the machine will flex under heavy load and that is why this project is for fun rather than any serious application. That said, it is a great little machine for hobbyists that want something to play with without having to spend a fortune.

It is created with the same concept as RepRap, using 3D printed parts and some easy to find “vitamins” (non printed hardware).

I tried to make it as cheap as possible, by using cheap electronics and a “low power” laser (a laser diode).
The X/Y working area is fully customisable and the max working object height is up to 50-60mm.

The cutter/engraver basically uses the 3D printed parts, M8 and M3 size hardware (rods, nuts,washers and bolts), some small bearings and GT2 pulleys and belts. I got most of the parts from my “old” RepRap printer.

The X/Y working area is fully customsable by changing the length of the 8mm rods.

The electronics uses an Arduino UNO with a cheap CNC shield and two Pololu based stepper drivers to drive two NEMA17 stepper motors.

My idea was for pcb designers to be able to quickly, without too much hassle, check their board for correct footprints (especially for connectors) and collisions between components. Currently one can change soldermask colors, silkscreen layers, move and rotate components around, change component models and import step files.

Hi, in this Instructable I want to show you how to create your own diffusor for a LED Matrix. To do this we will use a 3D printer and OpenSCAD. In this tutorial I will use a LOL-Shield by Jimmie ( http://jimmieprodgers.com/kits/lolshield/ ) also I will explain, how to design a diffusor for different matrix sizes and shapes.

As I recently was at the 31C3 in Hamburg i got a LOL-Shield from Jimmie. This shield is holding 126 LED´s which are Charlieplexed. After coding some animations and a game on it I thought that the LED´s where too bright. Because I wanted to keep the greyscale ( dimming ) of the matrix I decided to design and build a diffusor.

When MC Hammer rapped ‘You can’t touch this’ little did he know of the work being carried out by a group of scientists at Bristol University. The team led by Dr Ben Long and colleagues Professor Sriram Subramanian, Sue Ann Seah and Tom Carter have produced an ultrasonic sound system able to generate 3D shapes in mid-air that can be felt.

This project describes the design of a very low budget 3D Printer that is mainly built out of recycled electronic components. The result is a small format printer for less than 100$.

First of all, we learn how a generic CNC system works (by assembling and calibrating bearings, guides and threads) and then teach the machine to respond to g-code instructions. After that, we add a small plastic extruder and give an overview on plastic extrusion calibration, driver power tuning and other few operations that will bring the printer to live. Following this instructions you will get a small footprint 3D Printer that is built with about an 80% of recycled components, which gives it a great potential and helps to reduce the cost significantly.

The CircuitMaker PCB design tool could be thought of as the electronics enthusiast’s equivalent of Picassa, the free alternative to Photoshop – except that it’s a got a much more refined interface which makes it easy use. The program’s 3D modeling capabilities (more about that later) and other advanced features will help designers deal better with the “lumpy” nature of LED lighting products, or any other design project which involves large, irregular components. But that’s only half of the story. The software’s creators have also taken an interesting approach to solving several important technical and economic issues which have arisen with the Maker Economy by borrowing a few lessons from the movement’s own playbook.
