I'm going to experiment with using the H48C on a near space project.· It has a free fall detector that the documentation says is an output, active high.· There's no wiring schematic, so I'm assuming I can connect the pin directly to a Stamp (without a current limiting resistor).· Is that right?
When a balloon bursts, the near spacecraft begins falling.· I figure I can connect the freee fall pin to the psuedo interrupt of a BS2p.· That way my flight computer will know the balloon has burst in less than a second after the fact.
Did you know gravity is 1% less at 100,000 feet?· I don't know if I'll be able to detect this with the swinging of the balloon.· But if I don't try, I know I never well.
