Rocket Stove
andytompkins 

I love rocket stoves... For those that don't know it's a great way to cook with wood. The basic principle is to burn wood hot and fast, which is more efficient. So you insulate the fire and direct the heat to where it's needed... The pan!

Materials needed:
  • 2x 20 litre oil cans (easily found outside you're local kebab shop)
  • A cooking pot
  • Lots of wood ash
  • A length of 4" flexible flue (not aluminum dryer stuff)
  • Some sheet metal
  • A couple of lengths of metal tubes (optional)
Tools needed:
  • Tin snips
  • Work gloves
  • Drill
  • Rivet gun
  • Angle grinder (not essential but speeds things up)
  • Hacksaw
Work gloves are important, this involves lots of sniping of sheet metal and it can be a painful if you don't wear gloves!

 Guide to Professional 3D Printers
There are over 100 industry-grade 3D printer models currently on the market. These printers are large, commercial 3D printing machines intended for professional use. At Sculpteo we exclusively uses professional 3D printers.
We’ve put together a guide to these industrial 3D printers based on a selection of printers from each manufacturer that best represents the range of options out there — from price to materials to build size.
We hope this guide will help you determine the best 3D printer for your business needs. And don’t forget, you don’t have to buy your own printer to have access to professional quality 3D printing. Sculpteo offers an online 3D printing service using a variety of the printers listed in this guide.
Note on pricing: Because commercial 3D printers are sold through third-party, licensed resellers, there is not a standard retail price for each printer. Prices are only available via a quote from one of these resellers. We have recorded the pricing below based either on a quote from a reseller that asked to stay anonymous or from another online source (with a link).
The guide is organized by printer technology. For details explaining each process, check out The Different Technologies Behind 3D Printing.

Space: The Final (Maker) Frontier

Andrew Back

A look at three relatively low cost routes to getting your electronics project into space.
There was a time — not that very long ago — when if you wanted to get a functional piece of electronics into space it took an obscene amount of money and a few hundred tonnes of volatile rocket fuel. Suffice to say that, unless you were part of a national space programme, a global telecoms company or an evil supervillain, you were probably out of luck.
Thanks to ever smaller and lower cost technologies, coupled with a burning desire to get in on the action and a healthy dose of inventiveness, this is all changing — and at a somewhat rapid pace. This post takes a look at just a few of the options available for getting your project into space.









E esta Técnica cabe na Categoria de "porque é que ninguém pensou nisso, até agora?"!!!

Todos conhecem o Algodão Doce, mas podem-se utilizar Fibras de toda a espécie, para construír Estruturas leves e rápidas de fazer!
Até se poderá pensar em máquinas CNC para sabe-se lá mais o quê!

Spraying natural fibers to build cotton-candy surfaces

Zoe Romano

During Fab10- Fab Festival in Barcelona I met Jin Shihui who introduced me to CandyProject, a research project exploring the process of spraying natural fiber to create a non-woven textile that can be used to produce anything from building components to ornamental artifacts.
By means of air pressure we separate the fibers from a roving allowing them to self-organize and reassemble due to the surface tension caused by a fine mist of adhesive. This creates a controlled fibrous aggregation producing an emergent morphospace encompassing the initial substructure.
The robot Jin is holding in her hands in the picture above uses air pressure to separate fibers into individual strands. While the fibers are still separated they are embedded with an adhesive spray and all parameters are controlled within the robot  with an Arduino Uno:

A Caixa Pirata! E duas Dicas para a malta, Jon Cantin na TV, e Desenhos Vectoriais na vossa Página web!

Chamam-lhe "Pirate box", mas olhem que é uma bela duma ideia para quem tem maquinetas por toda a casa, ou para um Prédio onde haja muito Engenhoca, ou uma Universidade, Fablab, etc.



Raspberry Pi PirateBox  
talk2bruce

A PirateBox is a Linux based system built using free software for the Raspberry Pi that provides private sharing of digital content. The PirateBox creates a local WiFi network, independent from the Internet, with anonymous file sharing and chatting capabilities.

I wanted to make a PirateBox and create a cool looking case for it. I used a laser cutter to cut the pieces of the case from 1/8" thick birch plywood and painted it to look as shown in photos 1 and 2. A small Python program controls custom hardware that makes the arcs above the skull glow when the PirateBox is up and running. Another small Python program controls a push button switch that illuminates when the Raspberry Pi is powered up. When the switch is pressed, the program shuts down the Raspberry Pi preventing the problems that can occur if you just unplug a running Raspberry Pi.

Jon Cantin on the American Innovator! (video)
Jon Cantin

I filmed this a few months back with Paul Akers, CEO and founder of FastCap.com so this has been a long time coming.
There were some internet problems throughout the interview so what he recorded at his end (using webcam) just didn’t come-out after lots of tweeking around but thankfully, I also recorded the interview with my own Canon XF100 @ 1080HD and microphone so nothing was lost. I was focused on the webcam just under my video camera which is why I’m always looking down. We were very lucky that my microphone picked-up Paul’s voice coming from my laptop!

O Novo Raspi! E dicas da Emachineshop, um Detector de Radiações para o Povo, e a Caneta-Ferramentas

Dica da DesignSpark, eis o novo Raspberry Pi, diferente dos outros, logo à primeira vista, porque é mais interactivo com o Mundo Real.
Cá está o Raspberry Pi B+, cheio de conexões de, e para, o Exterior:

Introducing the Raspberry Pi B+




herbison 

If you enjoy interfacing your Raspberry Pi with the real world by (for example) connecting sensors or controlling LEDs and motors, there will have been times when you have wanted to have more inputs and outputs on the GPIO header, or a couple more USB ports for connecting peripherals. Well, the good news is that the folks at the Raspberry Pi Foundation have obviously listened to the growing community of Raspberry Pi users and developed an enhanced version of the Raspberry Pi called the model B+









Este é um muito bom Programa CAD grátis, que vos dá Orçamentos dependendo dos Materiais, e podem logo encomendar online a peça a fazer...
Estou a falar do Emachineshop, que vos dá isto tudo, e mais uma data de Tutoriais impecáveis, como este:



2D Trick 2: How to Draw an Arc Shaped Slot for Rotating Parts

Here's another handy 2D drawing trick you will likely need in the eMachineShop CAD software - drawing an arc shaped slot for a rotating part.











Com o que se passa no Mundo, não fará mal ter uma Gigajoga destas, um Detector de Radiações acessível, para qualquer um ter em casa,....
E esperar NUNCA precisar dele.
Mas para Sucateiros convictos, como os Engenhocas e Inventores, há sempre a possibilidade de acharem algo que querem ter a certeza que é inofensivo...
Ou não.










Small, portable and cheap radiation detector is being designed for the public

Ben Coxworth

Ever since the Fukushima nuclear reactor disaster, there has understandably been an upsurge in the sale of consumer radiation-detecting devices. Most of these gadgets are variations on the Geiger counter, in that they alert the user to the presence and level of radiation, but not the type of radiation – which is very important to know. Researchers at Oregon State University are hoping to address that situation, with the MiniSpec. Currently in development, the handheld device will additionally tell its users what type of radionuclide is creating the radiation, and whether it poses a risk.

Tool Pen by Mininch aims to be your go-to multi-tool

Adam Williams
Those in the market for a new multi-tool already have plenty of choice, but Mininch aims to stand out from the crowd with its Tool Pen: a screwdriver-like tool which draws inspiration from a 1980s kid's pencil and can carry six bits in its barrel. The company is currently running a Kickstarter campaign to help raise funds and bring its product into production.

The Tool Pen is made from aluminum, and is available in silver, champagne, or gunmetal. It measures 15 cm (6.2 in) long and 1.75 cm (0.68 in) in diameter – so it's bigger than your average pen, but still pocketable.
With the six bits inside, the total weight of the tool comes to 93 grams (3.2 ounces). The side of the barrel includes windows, which allow the user to work out where the required bit is, and there's also a magnet-secured lid to stop you stabbing yourself.

Layered paper 3D printers: Full colour, durable objects at a fraction of the cost

Loz Blain

Irish company Mcor's unique paper-based 3D printers make some very compelling arguments. For starters, instead of expensive plastics, they build objects out of cut-and-glued sheets of standard 80 GSM office paper. That means printed objects come out at between 10-20 percent of the price of other 3D prints, and with none of the toxic fumes or solvent dips that some other processes require.
Secondly, because it's standard paper, you can print onto it in full color before it's cut and assembled, giving you a high quality, high resolution color "skin" all over your final object. Additionally, if the standard hard-glued object texture isn't good enough, you can dip the final print in solid glue, to make it extra durable and strong enough to be drilled and tapped, or in a flexible outer coating that enables moving parts - if you don't mind losing a little of your object's precision shape.

Laser Cut Foam Inserts for Tool Boxes
tcolson
This is my first Instructable. Any constructive criticism in the comments will be gratefully accepted.
Lately I'm doing more machining at TechShop SJ. As a result, I've been carrying a lot of cutting and measuring tools back and forth from home. Many of the tools have precisions surfaces or are somewhat fragile. Remarkably, some of these came with no protective container. So, I decided to make some.
All of the work in this Instructable was done at TechShop SJ, my home away from home.
This Instructable is all about finding the best, least expensive foam from which to laser cut inserts to hold the tools safely in their boxes. Maybe I'll cover the finding/making appropriate boxes some other time.

Sketching & Drawing Lessons
ianbates1

Introduction:
I meet a lot of people in my job who say 'I wish I could draw like that' and they're surprised when I say 'Ok, I can teach you if you want'.
We often assume that drawing is a talent, something we are born with, some people can do it, some people can't.
But this is isn't exactly true; I failed my 'O'Level Art when I was 16. [don't get me wrong I'm not complaining I failed because I wasn't very good] and I didn't draw anything for a few years, why would I? I wasn't very good. To paraphrase a famous quote 'You don't know you are no good at something you enjoy doing, until someone tells you.' If I didn't know I was no good I'd have probably kept going and kept getting better. A couple of years later doodling away I realised I loved sketching and drawing and I wished I hadn't stopped and so I set out to teach myself how to become good at something I'd always wanted to be good at. I ended up becoming a design technology teacher/lecturer and teaching perhaps a hundred plus students these techniques.

Aqui está mais um Concorrente ao Rarpberry Pi, uma cavalgadura que é mesmo um PC em tamanho pequeno, o HummingBoard, que nas suas versões maiores suplanta alguns PCs que se vendem por aí...



HummingBoard is set to take a bite out of Raspberry Pi

Paul Ridden
Since shipping in 2012, Raspberry Pi boards have found themselves the brains of such diverse DIY projects as a mobile phone, a touchscreen computer or even a treat dispenser for the family dog. Now there are three new boys in town that promise faster processing, more system memory and more connectivity options. Yes indeed, SolidRun's new HummingBoard family has all the makings of a serious Pi killer.
...
The baby of the bunch is the basic i1 board, which features a SolidRun scalable micro System-on-Module (microSOM) that's home to a Freescale i.MX6 1 GHz single-core processor based on the ARM Cortex-A9 architecture, GC880 graphics with support for OpenGL and 512 MB of DDR3 RAM. There's no internal storage, but the computer comes with a microSD slot for loading in platforms like Ubuntu, Android, freeBSD or XBMC.

The i2 version is the i1's more powerful sibling, with a microSOM module sporting a 1 GHz dual-core processor and 1 GB of RAM. The i2eX model ups the ante again, coming with better graphics, 1 GB of faster RAM, and mini-PCIe and mSATA II connectivity. Gigabit Ethernet is also on offer, along with internal powered USB, an LVDS display out (with support for LCD and touchscreen panels), stereo analog out and microphone input to go with the SPDIF coax digital output, real-time clock support, and an IR receiver.

Interactive Physics Simulator for KDE 4
Tom Dryer
Step is a physics simulator for KDE 4. It’s meant to be an educational tool, but I’ve found it to be fun just to play around with also. Step was written as a Google Summer of Code project for KDE by Vladimir Kuznetsov.
If you’ve installed KDE 4.1 as I did in this post, then Step will be available in the repository. Step is a part of the KDE project, so if you’ve installed KDE from another source it shouldn’t be difficult to find.
