"Earl: I looked at the pcb layout, you must have some 0.1uF caps to decouple the 5V supply, located
right at the chip power and ground pins. Also a 10uF cap at least on the 5V. A ground plane helps a lot, too.
CPU's will not work without these caps.…"

"This sounds like a parallel to model rocketry legislation. After 911, the gov freaked, and instituted tough regs on
rocket engines and even fireworks. They forbid transport by train, which caused many cities to not be able to get fireworks for the…"

"Interesting, what sensors are you using. How did you program the different cogs? Is Spin difficult? What is
your programming background?
The Alt = 6494, yet it says 55" above the ground, how can that be? BTW, it is descend, to go down!"

"Earl, you may want to try the BaroMod, same cost, but provides a linearized output, 0.25mV per foot, so you
don't have to do nasty math to get a real alt. In hardware, an anti-log amp, the correct voltage is output to your
a/d input. The atmosphere…"
