The Rabbit Mill Desktop CNC

SourceRabbit  

Sourcerabbit is the brand name we created back in 2012, when Nikos decided that building someone else's dream fell short of his ambitions. Our dream is to establish a high tech CNC lab, that will manufacture awesome products. This will become a reality if we meet our goal. We would love nothing more than to be able to hire a full time Product Designer who can enrich our "Things we make can make a Life" Designs library.

Our passion for CNC machines and the need to create a fun and engaging work environment quickly united us to get to this first milestone: Indiegogo pre sales.

We both come from families who value building and restoring things, rather than buying new ones. Grandpa Siatras, a master craftsman, is the mentor of our Engineering skills, and built single handed the lab we work in. 

The main reason we are here is to validate our work. We have created an affordable and easy to use machine, but only you can make it meaningful.

As we are looking to expand, ordering parts at scale will help us keep the price levels we want.

A successful campaign will give us the energy to continue our R&D, which includes the HTML5 application www.cncwebtools.com and our latest hardware blueprints.

E já podem montar a vossa Besta Nerf de 6 peças apenas, mais 2 molas, cortesia deste vosso amigo, basta uma Munição Nerf com uma palha de Bebidas atrás, e podem praticar tiro-ao-alvo sem Stress nenhum:

Crossbow, 6 pieces and 2 springs only

Edgar Castelo 

A 6 piece crossbar, you put a Nerf ammo with a Soda drink straw on it. Can use metal springs or rubber bands, instead. 

Additionally, you can add feathers, and stick a metal piece on the straw, so a Neodymium magnet at the Crossbow's front will hold it.

Pitch Your Prototype… And Win $5,000

Jon Christian

Want a chance to win $5,000 and be featured at MakerCon New York this September? If so, consider entering the Pitch Your Prototype contest, a collaboration between Make: and Cornell University with the goal of digging up promising prototypes from the Maker community. Maybe you’ve been working on a wearable, or wrestling with a Raspberry Pi. Regardless, don’t be afraid to put yourself out there by entering—contestants in previous Make: contests have included an aerial film platform, plushies modeled on video game characters and an outrageous four-wheeled bicycle made from recycled materials.

Maquineta fantástica, dica do nosso amigo Fernando Mattoso Lemos, eis uma Ferramenta para os Inventores, que vos permite juntar Controle programável ao que precisem, como queiram, e au um preço bacano!

É bom, ou não?

Até a Microsoft está usando...

Open source design lowers cost by 2/3rds of building Raspberry Pi Compute 1&2 powered cool stuff.

Update : We are adding to the design support for Bluetooth Low Energy
Update : We are adding an IR receiver to OpenPi
Update : Check out OEM and EmonCMS running on OpenPi read more
Update : Microsoft are using OpenPi on Tech Days read more

Wouldn’t it be great to build hardware at the speed or cost of software?

OpenPi is an open source project, and a neat alternative to the Rasberry Pi Compute development kit. The holistic approach for non-embedded engineers, guides people who love to write software, through the problematic stages of getting small scale products to market. On offer are reference PCB’s, a customisable ABS case, open-source design files and collaborative design support. When it’s as easy to get up and running as a games console, and affordable enough for cottage industry inventors to profit from, OpenPi is forging a new way of bringing cool ideas to the masses.

New! Streamlined Support for Photochemical Machining

Making with metal just got a whole lot easier.

We are thrilled to announce new streamlined support for Photochemical Machining. Previously, if you wanted to create something using Brass, Copper or Stainless Steel, you had to take an extra step to email us the extra details of your order.

Now you can upload PCM design files directly to your Personal Factory account. In addition, you can now upload and get a quote for metal parts along with Laser Cut & 3D Printed designs at the same time, all in one order.

How to make with Photochemical Machining (PCM):

1. Prepare and save your vector design as a PDF using our Metal Machining Starter Kits.
2. Upload your PDF to your Personal Factory account.
3. Select your choice of metal materials and proceed to checkout as usual.

That’s it! You’re now on your way to receiving some awesome metal goodies in your mailbox. Please note: The design requirements for PCM are slightly different from laser cutting with other materials. You’ll want to be sure to read through our design guides before uploading your designs.

Achado através do Stumbleupon, o Site HowToGeek vem-nos ensinar como fazer de tudo um pouco, em Vídeo, com o programa Grátis VLC Media Player!

10 Useful Features Hidden in VLC, The Swiss Army Knife of Media Players

There’s a good chance you already use the VLC media player. But VLC isn’t just a media player — it’s a complete Swiss Army Knife for digital videos and music, filled with useful and fun features you haven’t found yet.
If you’re just using VLC to play back local media files, you’re only using a tiny fraction of VLC’s capabilities. There’s so much more you can do with VLC, whether you’re using it on Windows, Mac, or Linux.

E só porque sim, cá vão de embute, dois Instructables impecáveis...

Este, como fazerem uma Oficina num Móvelzinho articulado e cheio de truques, com rodas e tudo!

Complete workshop in a shelf

sachsie

Most Instructables projects require you to have some basic tools and a workshop available - unfortunately, most people do not have the space for these bare essentials available. Just like me.
My girlfriend and I live in a moderate sized apartment for some years now. We have got a spare room that offers sufficient room for our hobbies. Now we expect a baby and this room is assigned to it. As a consequence, I have to move all my tools in a tiny compartment of an IKEA shelf and have to find a new workspace too.
I approached this problem, by building a compact yet solid frame made of low-cost aluminum extrusions. It offers some very handy features:

• storage space and organization for my tools
• frame acts as a multi-purpose workbench. It offers:
  • a drill press
  • a router table
  • a bench vise
• Concept is very flexible and may find further extensions.

Everything is designed to fit the size of the compartment. Total costs of this project are about 150 EUR.

UPDATE! Backpacking Gasifier Stove

Quark-

Hello, this is Quark- and I am here to show you how to make your own TLUD (Top Level Updraft gasifier stove), and you can look them up at http://www.build-a-gasifier.com/gasifier-wood-stov.... They are essentially a stove that burns the fuel not once, but twice. The base thermos holes allow air into the fuel, while the top holes allow preheated air down into the stove to basically burn the fires smoke. I recently learned about the design while looking up specification for the popular Biolite Campstove, a design which I sought to make. Only then did I learn that it was a gasifier, and the rest is history. They are often used in third world countries, due to the fact that they are incredibly cheap to manufacture and are 10x more efficient than just a plain fire. Because of the double-walled construction, it is easy to use a simple food thermos to make one of these beauties. Enough talking, Onward!

Engenhocas ajudam o Mundo! E Thermite, a Dinamite dos Pobres, e o Cu-Box-i4 Pro

50+ Global Issues Makers Can Solve

Michelle "Binka" Hlubinka 

Lawrence Berkeley National Lab—along with USAID’s Global Development Lab, The Lemelson Foundation, The Schmidt Family Foundation, Dalberg Global Development Advisors, The Good Company and OMG—has put together a list of challenges primed for Makers to solve. They call these “Top 50 Game-Changing Technologies for Defeating Global Poverty.” These are summarized in a 20-page list, and then fully explored in the full 600-page report. They shared this list “because the problems we all seek to address require urgent action,” and they invite the problem-solvers of the world (you, dear readers!) to “begin the conversation.”

http://makezine.com/2015/02/15/50-global-issues-makers-can-solve/

Cá vai uma contribuíção da minha parte, desde há muito que se partem Rochas com fogo, e depois àgua, ou com cunhas em madeira, que se encharcam, mas depois, veio a Dinamite.

Mas em regiões onde não haja Dinamite, para Obras necessárias, ou até para destruír Minas já detectadas, (mas feito com um rastilho longo), que tal usar Ferrugem em pó, alumínio em pó, e gesso para o mesmo efeito?

Ou seja... Thermite! 

E de forma a ser moldado em qualque forma sólida.  

Atenção, no entanto, isto pode não ser tão perigoso quanto a Dinamite, mas é, à mesma, para ser manuseado por gente séria, e responsável...

Cast Thermite

Zlwilly 

There are plenty of Instructables and other how-to's on making Thermite, the incendiary mixture that can not only raise, but also burn, eyebrows. (The concept for this Instructable came from 'the Anarchists Cookbook', and since it doesn't give many details...here's how I do it.) Now, there's nothing wrong with powdered forms of Thermite, that's how I got started a few years back, but sometimes you just want something rock solid that burns nice and bright/hot.

That's where Cast Thermite comes in. And the best part is, If you have some thermite on hand already, it's pretty easy to make! If you don't, never fear, for I will be starting at the beginning with nothing but the raw materials.

http://www.instructables.com/id/Cast-Thermite/

 

E mais um Computador para competir e/ou ser conjugado com o Arduino e o RaspberryPy, este Cubo, o Cu-Box-i4 Pro vem com muita coisa mais, e a um preço bastante razoàvel:

Box-i4Pro, the small cheap computer in a cube  

Lara Lopes

You’re probably pretty familiar with the success of the likes of the Rasberry Pi and Arduino boards, tiny little computers packed onto a single bare board lapped up by digital enthusiasts and hobbyists. Well, the CuBox-i4Pro is not all that different except it’s packed nicely into a case and this small cheap computer in a cube not only packs quite a bit of power it comes at an incredibly reasonable price.

It’s created by Israeli startup SolidRun who created the first Cubox back in 2013 and we’re now on version i4Pro. The cube measures just 2.17” (55 mm) in width, length and height and packs Bluetooth and Wifi capability. The system comes with Android pre-loaded on a 4GB micro SD card and can also run Debian Linux.

3D Printed Prosthetics As Affordable Limb Replacements
 

Geoffrey Craig

As proof positive of the potential inherent in 3D printing prosthetic limbs can be produced at such a low price as to be within reach of millions of previously underserved populations. The use of the technology to manufacture bespoke prosthetic limbs is a revolutionary breakthrough for the millions of amputees of the world, in rich and poor nations alike.

Doutro nosso amigo, Alan Metcalfe, vem esta Dica, uma divertida ideia para vos tornar as Noites de Ciclismo mais seguras...

Cycle Chaser
Matt Richardson

Project animations from the rear of your bicycle. The framerate depends on the speed you are moving at.

A couple years ago, I created a dynamic bike headlight with a Raspberry Pi and a small, battery-operated projector. I’ve been eager to explore what else I could do with a projector and a Raspberry Pi on my bike, so I created the Cycle Chaser.

http://makezine.com/projects/cycle-chaser/

Já não me lembro de onde veio esta dica, mas é uma boa oferta para o Ano Novo, um Guia para as Impressoras 3D:

Which 3D Printer should I buy?

is the most common question we at 3D Hubs are asked.

We reached out to our global community of Hubs to learn from their experience and see what they thought of the 3D Printers they own. The 2015 3D Printer Guide is based on the reviews of 2,279 verified 3D Printer owners. Their collective 1623 years of 3D Printing experience coupled with 317,000 prints completed on 235 different 3D Printer models, makes this the most comprehensive guide available.

Folded Plate Chair #3B

michael.cobb.1610092

This is a design for an "origami style" plywood chair. After doing some initial prototypes with various sheet goods and continuous hinges I settled on this design as a good balance of affordability and quality.
