Re: Three ball bearings
Many years ago a friend worked for a Government Department and produced a small computer device to be used by the Armed Forces. It had to be very robust - water-proof, accept input voltages of almost anything under 50v DC and of any polarity. His final task was to find a simple way of destroying it in an emergency. I think he opted for something thermite-related which caused all sorts of Health & Safety problems.
