How did you manage meaningful attitude control with only torque rods? They would need to big (read: heavy) to be useful — was this just stabilising in inertial frame or active pointing?
Mag dipoles in chassis and components tend to lock tumbling satellites into the Earth’s magnetic field. Did you see this? Or did you see atmospheric drag dominate at this altitude?

I don’t doubt the physics, but I’m not sure about the experiment design. Being able to hear the correct frequency may just mean you’ve built an oscillator and tuned it.
Honestly par for the course for human treatment of chickens. See chick culling [1]. Billions of baby chicks are macerated live because they are not commercially useful.

Just checked linkedIn, yep they are from NSW.
