helped write the payload control software for [link|http://www.wff.nasa.gov/~sspp/gas/sts/sts-90.htm#G744|G-744], a shuttle [link|http://www.wff.nasa.gov/~sspp/gas/|Get Away Special] payload. Not much really. Just a take a reading, take a picture, wait loop on a custom 68HC11 computer. Tis the sum total of my embedded programming experience. Most of what I did was manufacturing and CAD work. I also worked on [link|http://www.wff.nasa.gov/~sspp/gas/sts/sts-57.html#G399|G-399] and [link|http://www.wff.nasa.gov/~sspp/gas/sts/sts-64.html#G178|G-178] (that's me 3rd from the left).
It looks like I should document this somewhere. The old page for the project seems to be gone now.
