Rocket DASs
I can't resist commenting on another rocket DAS which has a block diagram similar to that of the Nuvation board. It too was a single-board computer/acquisition/control subsystem that I designed in the 1990s as part of a "hobbyist" effort for the Great Lakes Rocket Society to build a 22 foot LOX-kerosene liquid-propellant rocket around an Atlas vernier engine with a 1000 lbf thrust rating.

The board has yet to be applied to this particular rocket application, though it moved closer when Pioneer Rocketplane in Colorado considered using two of them for instrumentation in a third-stage bantam-weight upper-stage design for NASA.  Its 1 MHz clock-rate 6502 was enough to scan in 24 channels at a fast enough sample rate, using a system timer to generate 5 ms interrupts for channel sampling. I included it and basic DAS concepts, especially from a software processing standpoint, in a book titled Rocketry and Astrionics, described in more detail at innovatia dot com.

A similar uC system was used by the USAF in New Mexico in high-altitude balloon data collection, with a perfect flight record. In this case, no particular requirements for cooling the board were given, though the atmosphere at the top of the troposphere is hardly the deep vacuum of low-earth orbit!

Re: Call girls in Goa
@agariogames---- What about this article? No tech commentary on this excellent work done by Nuvation?

I am providing the best tech blogs here in the industry. Don't comment only on the negatives, but please do comment on the positives---that's what our audeince wants. I will take care of the hackers.

Re: Call girls in Goa
@Agariogames---It's like 'swatting' flies nowadays in journalism with all the hacking invading our sites. I do my best as does our IT team, but the hackers are relentless; however, we are vigilant and they will not win!
