I have just built my first Magnetic Apogee Detector. This is a small interesting electronic device for detection of apogee
by the magnetic field around the earth.

I´m going to use this detector in my MR-1 Rocket, to control the drogue chute, and then I will have the RDAS to control
the main chute.

Here are the first pictures of my MAD.
(Pics. are quite big for better view)
