I have quite a bit of >electronic knowledge, but programming is greek to me. As someone who has put computers in rockets before: Avoid crystals. Internal R/C oscillator, or external resonator is a much better choice. Xtals are internally fragile, and they don't like high accelerations. If you can keep the long axis of the crystal in the thrust line, they do a little better, but it's not worth it. -- http://www.piclist.com#nomail Going offline?
