3D Printer "homemade" new concept (short version)
Nuno Silva

This 3D printer has a much lighter warm bed frame. The warm bed frame weighs 150g without linear bearings! The base and top are round because I reused these parts from an old project. This printer has a print volume of 200 x 200 x 200 At the last minute the printer is printing a frame for the warm bed of a 300X300X300 printer

Algo de bem útil, e que podem fazer com as Ventoínhas dos PCs, um Dremmel feito em casa, com o motor Brushless que recuperam do centro das mesmas, depois de descarnarem o plástico...

É bom!

DIY Brushless Dremel Tool
DIY KING 00

Its been almost two years as I got my first batch of cordless tools, most of them were brushless so love the amount of power these tools offer.
With me scratching my head about what to built next I had an idea to built a brushless Dremel tool thats powered by those high capacity lithium ion batteries.
Well the idea sounds good but the challenge it to make that brushless Dremel tool without throwing a lot of money on parts and making the whole project as easy as possible.
So the goal is to built a brushless Dremel tool out of scratch. So get through this intractable in which I am going to show you how to make a Brushless Dremel Tool under just 15$.
Lets get building…

3D Printing Repairs a 1920 Ruston Hornsby at Siemens UK Materials Solutions

3D Printing Nerd

While visiting Materials Solutions in the UK, I got to learn about a couple 1920 Ruston Hornsby car Siemens UK were restorying. Thanks to some 3d scanners, some cad software, and some highly talented people, they are able to replace functioning metal parts on the car - parts made in 1920 that you cannot find anymore! COOL!

Ou fazerem as 3! 
LOL

Sigam este primeiro Instructable, com vídeos dos 3 tipos de Impressoras, e a explicação de cada um desses tipos, para poderem escolher:

Building a 3D Printer
Core3D

I recently presented 4 3D printers at the Maker Faire Milwaukee. All 4 were designed and built by me. I'll share the links to 3 of the instructables that explain how to build them. This instructable however, is going to take a more general look at what to expect when building a 3D printer.
One repeating question I get at shows is, how much it costs to build a 3D printer. The answer depends on what you're building but, of all my printers the minimum is about $400.
The follow up question is, why you would pay that kind of money for parts, if you can buy a 3D Printer for less than that. Good question and here's my answer to that:

You only would build a 3D printer if you want to experience the process of building a printer. Yes, it can be more expensive (I won't pass judgement on the quality of the cheaper, ready made products) but think of the process of building a printer as a learning experience. You are paying for the experience and out of it you happen get a working project.
One of the most remarkable things about building a 3D printer is that you'll amaze yourself (and can take great pride in) at what you are capable of.
I built (and to some extend) designed my first printer 4 years ago without an ounce of experience in robotics and electronics.
A fair warning: Building a 3D printer is like getting a Tattoo; it will never end with one.

Making of a DIY Flightcase
TangLB

I have some sound equipment and I needed some kind of box to store my lights and various accessories.
I realized a few months ago a "DJ suitcase" a kind of flight case, with mixer and light dispatching (picture at the end of this project), I decided to detail you the steps of the realization of this new "case".

DIY IRONLESS LINEAR SERVO-MOTOR
Vulcaman

Hi,
in this Instructable I want to show you, how to build your own Linear-Servo-Motor for Linear-Movement-Applications.
But at first the story about this Instructable:
When I visited one of the biggest trade faires for Automation here in Germany, I saw a lot of Linear-Motors in Industry Applications. It was quite astonishing how fast these Motors can move with an incredible precision.
I thought it would be really cool, if I could addapt these kind of motor in a Laser or 3D-Printer Application. Sadly these Motors are very expensive (>1000€ per piece). So buying a Linear-Motor is not an option anymore. But after some research I thought it will be possible to build my own Linear-Motor. Theoretecly a Linear-Servo-Motor is just a three phase sychronous motor with a closed loop position feedback. So I started to create CAD-Drawings and Electronics. After one month of research and improvements I can say, I have built my own working Ironless Linear-Servo-Motor. However there are some points which need to be improved especially in the position regulation. This project helped me a lot to understand, how a Linear-Motor works in general, and how to programm a closed-loop controller for it.

Então, e porque não, usar a vossa Impressora 3D, para a afinarem? 
É o que fazem, com esta ferramenta para nivelar a vossa base de Impressão:

LED 3D Printer Bed Leveling Tool

TechKiwiGadgets

Being new to 3D printing I found leveling the print bed a challenge, particularly on printers without auto bed leveling. This 3D Printer Bed Leveling Tool uses a Pulse Induction Metal Detection Sensor and a LED Bar Graph to show the relative distance from the Print Head to the hotbed. This is an independent add-on that does not require any code changes to printer firmware or wiring. It is easy to quickly attach to check and tune bed levels then remove.

Easy Tesla Coil!
DrewPaulDesigns

Wireless electricity is here! From wirelessly powered lighting to wireless chargers and even wireless smart homes, wireless transmission of power is an emerging technology with innumerable applications.
A light bulb powered with no wires? A cell phone charger that doesn't need to be plugged in? A home with no plugs, no wires and everything just 'works'? It's not magic, it's no mystery, it's science!
The invention of wireless power transmission is typically attributed to 20th century inventor Nikola Tesla, though the technology may have been in use much earlier. Since then, however, improved designs and modern components make this an easy DIY project anyone can do with just a few simple parts!

Bladeless Drone: First Flight
Stefano Rivellini

With 4 ducted fans, and some carbon fiber, I built a bladeless drone that I think is one of safest in the world. It uses 4, 90mm ducted fan propulsion units buried deep inside what I call a “bent tube” propulsor. The fifth “leg” is a parachute can. Hopefully I will never need it. With some help from my dad, we built the entire airframe primarily out of carbon fiber and some balsa wood. I bought all the electronics on line and was able to design the drone so that it would operate with a standard DJI multi rotor flight controller even though it doesn’t have vertically oriented propellers. With its top mesh installed its virtually impossible to get fingers and objects in contact with the blades. I submitted a patent application for my invention. I think a drone like this could have industrial applications where a drone needs to operate close to people, objects, and in confined spaces to do inspection and other activities.
