A new twist to the hot wire foam cutter  

dave spencer

I'm not going to go into too much detail on building a hot wire foam cutter here. There are tons of great instructables and videos already.  I am going to show you how my laziness and impatience in building one paid off with a new material to use that will allow you to bend the wire into shapes to cut with.

Como há Lojas das Rodas em todo o lado, podem fazer esta Bicicleta sem pedais, que é muito melhor para habituar os Míudos a andarem de bicicleta, que as miseráveis Bicicletas com Rodinhas...

Draisienne en bois pour enfant

Zeloko

Voici une draisienne entièrement réalisée en frêne.
Le cadre et la tige de selle a été réalisés grâce à la méthode du lamellé collé. Alors que tout le guidon est en assemblage tenons / mortaises classique.
L'idée première était de tourner les roues de 12 pouces en bois. Mais n'ayant pas trouvé de solution satisfaisante pour le contact avec la route, je me suis rabattu vers vers des roues classique avec pneu et chambre à air. Faut pas toujours tout réinventer ;)

Máquina que Faz Filamentos Para Impressoras 3D

Laboratório de Garagem

Após adquirir uma impressoras 3D, um dos maiores custo que você terá é com relação ao filamento de plástico (ABS e o PLA) que da forma as peças que imprimidas.

O custo do material não é elevado, o grande problema e depois do beneficiamento que ele recebe para se transformar em filamento o preço chega a aumentar 10 vezes.

KneXtreme's Pallet Projects 

KneXtreme

 

We moved a few months ago and I noticed behind the new Taekwondo school that I was going too that there were a bunch of pallets. I asked if I could have some, and they said I could have as many as I wanted. Since then I've been building stuff out of pallets left and right.
This is a little guide showing all the stuff I made out of those pallets and some of the tricks I've learned taking them apart, preparing, and finishing them.

Each step is a different pallet project with the exception of the first 3. All the projects have the general dimensions of them with the exception of the coffee table which has the specific dimensions of the wood, incase you want to build it. Also, let me know if you want specific dimensions of other projects.

DIY Multifunction Pocket Tool

Matt2 Silver

 

I started this project because I wanted a more convenient way to carry and store the variety of 1/4" bits that I like to keep with me for my day to day tinkering.  Once I had something that served that purpose I thought it would be fun to try to pack in a bit more utility by adding on some features that I thought may be useful, or at least pretty cool to have on hand.  What I ended up with was a sort of DIY Pocket Tool that can be customized to meet your needs, that is simple and inexpensive to make.

The $74 PVC Mega Awesome Super PVC Table 

trevormates

Wow.  It’s been a long time since I’ve posted an Ible! I ended up using PVC again for an office project and thought I would share how and what I built with it, since I get so many questions in my inbox about PVC.

As the title states, this Instructable will show you how to build an VERY large table out of a hollow core door and PVC pipe and fittings. They can be used for anything, such as craft tables, train tables, light desks or for garage sales or even family dinners as a ‘kids table’.  It is entirely up to you.  We needed ten of them and we use them as desks.  This was our first one we built.

Energia Grátis Made in Brazil? Mais um Comparativo de Impressoras 3D, um Arduino impresso em Papel, e um Tear-Robot!

Poderá ser verdade, em breve, termos a nossa própria Electricidade, grátis, graças a dois Inventores Brasieiros!

BREAKING: Inventors Harness Free Energy with New Device 
BRAZIL | Has the secret to boundless free energy been discovered? Well according to two Brazilian inventors it has.

On February 11, 2013 the two inventors posted a video of themselves demonstrating a device powering a bank of lights.

A few months later, On July 7th 2013, inventors Nilson Barbosa and Cleriston Lea filed an international patent on on the device stating it will produce free energy. Now the pair have stated they'll be selling the small device to the people of Imperatriz, Brazil.
Its called the Earth Electron Captor Generator, and according to the patent it works like this, "Earth Energy is electromagnetic energy that can be instantly obtained to perform work through an electromagnetic field connected to earth"

After an initial "power up" from "any" electrical source a sensor begins to rotate creating what is known as "over-unity power"
Over-unity devices have long been criticized because some claim it violates the laws of physics. however this has clearly not stopped Barbosa and Lea.

The pair have created multiple sizes of the generator. The smallest is capable of generating 12.1 kw of power, with a load of 6000 watts, using only 21 watts input energy. The team believes it can power a family home or automobile.
It should be noted however that anytime technology such as this surfaces, it generally disappears just as fast.

2013 3D Printer Comparison Guide

Randall Marsh

The 3D printer industry is growing in both the professional and maker markets. With more and more 3D printers diving under the US$4,000 price-point, is it time for you to pick up one of your own? Though the consumer end of the market is still young, business is booming, and this disruptive technology is something that will definitely appeal to many Gizmag readers. That’s why we’ve taken the top desktop 3D printers and lined them up for a side-by-side comparison.

Paperduino 2.0 with Circuit Scribe - Paper Arduino 

Electroninks

What if making an Arduino, or wiring up an Arduino was as easy as printing one out? In this tutorial we printed our own Arduino Pro Mini board using a pen plotter and the Electroninks Circuit Scribe (a rollerball pen with highly conductive ink). Within 15 minutes we printed the board, placed components down with glue or tape, and uploaded a sketch.

Introducing Climaduino - The Arduino-Based Thermostat You Control From Your Phone! 

bbustin

Not everyone lives somewhere with central air, or is willing to pay for a Nest or similar "smart" thermostat. The Climaduino is a DIY Arduino-based thermostat designed to control a wall unit A/C. I incorporated both temperature and humidity sensors in order to optimize comfort and reduce energy usage. I then developed a Raspberry Pi-based web interface to control the Climaduino from my phone.

Raspberry Pi Wall Mounted Google Calendar

Piney

Recently I purchased my first home. In the kitchen there was a small TV wall mounted however the TV itself was faulty so I was wondering, what should I do with this wall bracket since I didn’t really want a TV in the kitchen area. Then it dawned on me, instead of using a paper calendar with tiny little boxes to write things in I want my Google calendar on the wall.

To tackle this instructable you should have a general understanding of home networking and computing, some linux experience wouldn’t go astray but is not really necessary. If you run into something you don't understand just remember google search is your friend.

3D Printing: 3D Print A Solderless Circuit Board 

mikey77

Experimental circuit boards can be easily made with a 3D printer. They can be made at the same size and thickness as a standard 1/16" thick, through-hole soldered, perfboard.
The components can be fairly easily connected together without using solder.

This technique is somewhat faster than standard etched and soldered circuit boards. But it does require some skill and attention to detail to create a reliable circuit.

This example circuit board is a simple micro controller circuit that flashes three LED's in sequence.
It is intended to be a minimal illustration of what is possible.

Você mergulha o objeto em um líquido e ele sai impresso

Affonso Orciuoli, e Victor Sardenberg

Profissionais que trabalham com aplicação de materiais em superfícies ou sólidos em programas 3D, como 3DMax ou Rhino, conhecem as dificuldades em controlar a técnica conhecida como "mapping", que nada mais é do que vincular uma imagem tipo bitmap a uma superfície que tem um tamanho real (CAD). São vários os "presets" para a façanha, e dependendo da geometria, é algo bem dificultoso.

Bicycle Frame Building Jig 

Tanner W

A little over a year ago I took a bicycle frame building class through the United Bicycle Institute. I attended the chromoly brazing class at their Portland campus. Since then I have wanted to build more bike frames. I am interested in making money doing it, and perhaps someday, making it my sole source of income. On the path to becoming a bicycle frame builder one of my biggest obstacles is acquiring a frame building jig. They are expensive, arguably the most expensive single tool you need to accurately build quality bicycle frames. So I, like many bicycle frame hobbyists, decided to build by own. My personal goal for my frame jig however, was to build a professional quality frame jig. I wanted something I could potentially start a business with.
