E se quiezerem um Arduino, e só tiverem 5 Dólares?
Pois FAÇAM um, e com muitas capacidades, e ainda, sem necessidade de um programador externo, que já já está um dentro!
Gduino-No Programmer Required!! for 5$,Programs Multiple AVRs
Gursimran Singh 425
Arduino is familiar to anyone who loves to build tech.It is very common in project makers.But why 25$ For this board!! We can make our own!! In this instructable I am going to show you how to build an arduino at home that doesn't need any external programmers like USBASP or serial communicators.USBASP is already embedded inside this circuit!! I was impressed by bjkayani's instructable Beeduino ,the tutorial is well detailed and also Thomas Fischl's USBASP.I decided to make both these circuits on one board.Not by soldering a perfboard or on breadboard but on our very own built PCB!! Yes we can make it at home!! I will show two ways of etching PCBs and also tell which one would be better!! The other interesting thing is that I made it in just 5$ 5 times less than that of original arduino. And also we can program many other programmable ICs like ATtiny45/85 etc.Enjoy!!
Alinhar os vossos Desenhos Vectoriais para o Corte CNC pode ser um problema, mas este Programa Online, e Open Source, faz esse trabalho por vós, para poupar tempo, e Material:

SVG Nest
What exactly is "nesting"?We have some (2d) parts to cut and a piece of material, we want to arrange the parts to use as little material as possible. This is a common problem if you use a laser cutter, plasma cutter, CNC machine etc.In computer terms this is called the irregular bin-packing problemHow much does it cost?It's free and open source. The code and implementation details are on Github
Poderão talvez aproveitar o tal Arduino acima mencionado, para fazerem mais esta máquina CNC, e fica tudo em casa!
How to Make an Arduino Powered CNC Machine
AbsorberOfLight
Step-by-step instructions on how to build a low cost CNC machine controlled with an Arduino Uno!Roller skate wheels will be used to create the X-Axis sled. A combination of 2in and 1in steel tubing will form the base of the machine.

How to make a mini Gas-jet (up to 1000ºC)
Roman UrsuHack
Gas-jet (up to 1000ºС) with your own hands!With the turned on blowing the gas-jet has a good heating power, it can set alight a plumbeous pellet in a few seconds (up to 1000ºС)!In conclusion I'd like to say: this gas-jet may be improved by installing an ergonomical (pistol) handle and add the piezoelectric element for lighters for the facilitation of firing.
E aqui está uma Tecnologia mesmo à espera de ser trazida para o Universo dos Fabbers, dobrar Chapa por controle CNC, até ela ter a forma que desejem, para o que quizerem...
O exemplo é de Chapa de Aço, mas imagino que Folha de Latão ou Alumínio estará ao alcance de máquinas caseiras:
Ford's Advanced Prototyping, Personalization and Low-Volume Production Technology
Ford Media
Ford engineers are developing a highly flexible, first-of-its-kind, patented technology to rapidly form sheet metal parts for low-volume production applications. Once fully developed, the technology (Ford Freeform Fabrication Technology, or F3T) will allow for lower costs and ultrafast delivery times for prototypes -- within three business days versus conventional methods that take anywhere from two to six months.
