Arduino

The Arduino is a open-source electronics platform based on user friendly hardware and software. Used right you can do a multitude of things with it. One of the most impressive things I’ve seen done is a working CNC machine. Which if you didn’t know a Computer Numerical Control machine(CNC machine) can make a cutter move with pin-point accuracy. Low end CNC machines can go for $5,000 and higher end can go for much higher than that. With the Arduino, you can make a working CNC machine.
