Re: Future use of cRIO?
The white plastic parts were rapid prototyped via SLS. I am head over heels in love with the fact that in the time it takes the board house to build my boards, the ME can design AND GROW its enclosure. Thank you Altium, Thank you SLS, Thank you Simon.
I am unsure of exactly what the material we used is. Production models will be injection molded.
I will tip my hat to the NI folk, but I believe the cRIO is die-cast, possibly sand blasted, and then painted. I don't believe it is cast iron; I'm leaning towards aluminum.
As for U2, Greg is absolutely correct. It simply adds current drive strength to the DIO. The victors require a few milliamps to turn on. A standard hobby servo signal requires almost no drive strength, and could be run without the buffering stage.
