Impressora 3D feita em casa, em Portugal! E uma Dremmel DIY, Foguetes de açúcar(!), Reconstrucção Histórica, e Vigiância Nocturna

Um projecto feito em casa, e vão vè-lo, no fim, a imprimir, como se fosse comprado à loja, eis o que o nosso amigo Nuno Silva promete eventualmente oferecer como Open Source.

Portugal avança...

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…

Para uns momentos de diversão meio maníaca, mas inocente, nada como fazerem os vossos Foguetões miniatura a partir de quase nada, e porque não, usar isto como uma desculpa para imprimirem os Foguetes nas vossas Impressoras...

Para verem como se usa Impressão 3D, profissionalmente, para restaurar Máquinas que fizeram História, por Scan 3D, Impressão, e adaptação paciente, cá está este vídeo do nosso amigo Joel, do Canal 3D Printing Nerd:

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!

DIY Professional Open Source Night Vision Security Camera

Blackir

In this new tutorial, we will together make our Raspberry Pi open source video surveillance camera.
Yes, we are talking here about a real open source outdoor surveillance camera, capable of night vision and motion detection, all connected to our Jeedom domotic solution.
Now let's have fun. ^^

Façam o vosso próprio Micro-PC! E Motores a partir das Impressoras, um cartão de Visitas Digital, e uma Base para Fresa Dremmel.

Com muito pouco, fazem o vosso próprio Micro PC, daqueles que carregam directamente dum Chip, usando este Instructable:

Make your own 'Home Computer'

gfwilliams

Many of us learnt to program on a Sinclair Spectrum, Commodore 64, BBC Micro or similar - 8/16 bit Home Computers. These computers booted straight up to a command prompt and encouraged you to write code and play with them.

You can now make your own (that runs JavaScript) in a few hours using a Espruino Pico microcontroller!

E que tal fazerem um Quadracóptero a partir das vossas Impressoras? Ora aqui está uma ideia mesmo bacana...

Upcycle Brushless DC Motors From Printers

ossum

If you are at all interested in robotics and electronics you will probably have disassembled an old printer or two (if you haven't, I highly recommend it, there are always interesting parts, and you can learn a lot about how the experts put electro-mechanical machines together). If you have taken a laser printer apart, you will likely have come across brushless DC motors, which range in size.

These motors have some pros and cons, obviously it varies between printers, and the functions of the motors within the printers, but I have found the following to be true most of the time

Aqui, explica-se como vocẽs podem ter o vosso próprio Cartão de Visitas Digital...

Pois não é que esta gigajoga transfere o vosso Contacto, para o Smartphone de quem vocês conhecem?

Simplesmente... Fantástico! 

Digital Business Card with NFC

Joep1986 

NFC is found everywhere these days from credit cards to door locks, but must importantly: your smartphone! With a few simple steps and relatively low costs you can create a digital business card that uses NFC and can be read by a smartphone to transfer contact information. This high-tech solution makes exchanging your contact information not only fast and easy, but also makes you look very cool!

(this Instructable was made for the TfcD course @ TU Delft)

E se têem uma Dremmel, ou uma Maxcraft, etc. podem agora fazer um brilharete, com trabalho de Fresa, o que é sempre mais uma funcionalidade para estas pequenas maravilhas...

Notem o genial uso duma Pré-ferramenta em Cartão, para fazer uma Ferramenta final, em Madeira!

Ahá! 

O Génio Inventivo, está vivo, ainda!!! 

Wooden precision mini router base for rotary tool (with cardboard prototype)

maKACS

 

I have a Dremel like rotary tool and I wanted a mini router base for it. It can be bought from Dremel or Stewmac e.g.

http://www.dremel.com/en-us/Tools/Pages/ToolDetail...

http://www.stewmac.com/Luthier_Tools/Tools_by_Job/...

but I decided to make one. Made an initial research and found some good and nice examples:

I decided to make it 3 legged to increased stability and wanted to try it, so I made a prototype out of cardboard.

Let the fun begin!
