That's not going to sell a lot of units, though. Its hard enough to get a machinist to set up a cnc system with a full gui. You want him to disable interrupts on Linux? Just shoot me now.

G-code is indeed an old language, but it's the industry standard because it's better than all of the alternatives. There are complex G-codes, such as threading, which allows you to define the pitch, thread depth, cutting style, th

In PC based CNC systems, there is almost always dedicated hardware separate from the PC that is feeding the motor drivers, because Windows and Linux are not true real time operating systems. A cnc system must have a timing resolution much

What sort of IP does MakerBot have? Its a reprap (fully opensource) that needs slightly-less-constant maintenance, and they've iterated on the extruder about 10 times. There's also some software. If $400,000,000 (possibly $600,00

Just about every pin on this processor can be used for GPIO. Some pins, like the DDR interface, can only perform one function, but the vast majority can be configured to do one of seven different functions.

I haven't actually worked with the raspberry pi, but I'm currently working with a similar processor, a Texas Instruments ARM Cortex A8 that runs at 720MHz. On my processor, you have to set up the PLL to take the 24MHz external oscillator t

This is true of any processor. If you had the inclination and the proper hardware to facilitate loading the machine instructions, you could program the processor in your computer the same way. The raspberry pi is a much more complex machin

The $22K price is for an incomplete system. The two missing pieces (hands and base) sound pretty integral to the system as well. What is the point of listing a price of a useless configuration?

The gyroscope keeps the vehicle from falling over when stopped. Even without regenerative braking, thats pretty necessary complexity when you can't stick your foot out to add a third point of contact.
