Protejam o que é vosso! E uma Gravadora Laser a partir duma Multi-Funções, CNC à la carte, e uma casa de Pássaros a partir de Sucata.

Eis uma boa ideia, que merece ser divulgada, porque com a Esterilidade e o Cancro... 
Não se brinca!
E os rapazes têem talento, e fizeram algo com estilo.
Por isso, e pelos vossos... 
Bens de Família, hum...

SafeSleeve: The All-in-One Radiation Blocking Laptop Case

 Development Process
After hearing from a professor that using a laptop on your lap may be harmful to your health and later confirming this with some thorough research, we made a profound realization:the convenience of being able to use a computer anywhere, anytime often causes many of us to ignore the associated consequences.

With You and Yours in Mind


Dando asas à qualidade básica que se desenvolve, de se ser Engenhocas, o Sucateirismo desinibido, eis como podem fazer a vossa Gravadora CNC, que também corta Esferovite, ou Isopor, e até folha de Plástico fina...
A partir duma Impressora Multi-funções descartada!!!
É bom!

Frankenstein Laser Engraver 
This Frankenstein Laser Cutter was built out of an old scanner and printer.
The whole thing evolved around the instructable of Groover and his 'Pocket Laser Engraver'.
This is a Making-Of. Although a lot, if not everything, of the mechnical construction requires ingenuity I tried to document the complete build process as much as I could. Every scanner and printer mechanics are different so this could not be used as a step-by-step guide. More of a "how it can be done"-guide. I try to cover the questions that could arise in the process of making.

A Inventables é bacana, já vos vendem Impressoras 3D, e 2 Modelos de Fresas CNC, destacando-se esta pequena maravilha...

Mini CNC Engraving Router

For all purpose cutting and engraving

This machine can cut and engrave almost any material. It includes a 10,000 rpm spindle, aluminum T-slot table and clamps, and 3x router bits. The 3x Stepper motors are premounted and fully assembled and wired. All motors have hand turn wheels to move the machine manually and the machine has a plug and play 110 power supply / control box.
E ainda por cima, se quizerem fazer a VOSSA CNC...
Eles fornecem-vos o Controlador, um Shield Arduino já com 3 Drivers de motores Passo-a-passo!

grblShield (v4)

Arduino shield with 3 stepper motor drivers built in

The Arduino grblShield is a complete hardware solution for Dank’s CNC motion control system called grbl.
Compatible with the Uno and other 328p versions of the Arduino development platform. (Note: grbl 0.6 is not compatible with 168-based Arduinos (nor will it ever be), and currently grbl does not support the Arduino Megas). 
grbl Features:
Interprets a subset of rs274/ngc standard gcode
Three motion control axes – X, Y and Z
Full support for arc motion
Acceleration / deceleration management
grblShield Features:
Compatible with grbl 0.6 and later versions
Three stepper motors supporting X, Y and Z axes
8x microstepping
2.5 amps per winding (bipolar steppers)
12v-30v motor voltage supported
Independent current control per axis
Motor connectors plug compatible with RepRap and Makerbot electronics
Uses TI DRV8811 stepper drivers

E voltando à bela da Sucata, eis uma Casa de Pássaros impecável, a partir dum Frasco de Plástico, isto também é uma ideia com Estilo...
Embora eu cá, punha-lhe também um Poleiro.

Plastic bottle birdhouse 
Ruud van Koningsbrugge

Isn't that the best thing there is? Use your plastic waste for a bird-nursery. After your clothes have been refreshed you step out in nature and you hear the tiny squeaks of little birds housing in your former detergent bottle.

It is easy to make. No special skills needed. And very basic tools.
Still the result looks streamlined like proper designer stuff.

Photo's shown throughout this instructable show a big and a smaller birdhouse, both made in similar ways with minor differences.
The blue rimmed one ismy first built and it is the bigger one. Most instructable steps show the second built one.
It depends op the type of bottles you can find, how the end result will look at the end
