Is there a beer icon?
Because the folks at NASA deserve one for this.
Re. hacking accelerometers, do they work better at low temperatures?
One would assume several effects interact including the "stiffness" of the beam(s) and noise in the measuring
chips as well as frequency shift taking it outside the preset passband for the on chip filters.
I might yet be able to put my vintage 2007 PS2 golf game sensor(s) to good use as these are an older type
with analogue versus digital outputs so some rejigging might make them more sensitive at certain frequencies.
A good method would be fluctuating the power supply using a feedback PID loop tuned to a harmonic of the on chip
sensor drive (most likely in the low MHz range)
