Vuilleumiers Laws For Building Electronic Prototypes: First Law – Any pre-cut equipment is too short; this is specially true of optic fiber cables with expensive connectors at both ends. Second Law – If n electronic components are required, n-1 are available. Third Law (also known as Selective Gravitational Field) – Any tool escaping manipulators hands will not necessarily follow Earths gravitational field, but will land in the most unreachable location in the prototype, smashing on its way the most expensive component of the prototype; this will know only one exception if the tool is particularly heavy, in which case it will land on the manipulators foot. Fourth Law – When proteup first, thankfully leaving the fuses intact. Fifth Law – Prototype npn blackboxes actually hold pnp transistors, and vice-versa. Sixth Law – A quartz oscillator oscillates at a frequency off the rated one by a minimum of 25%, if it does oscillate at all. Seventh Law – When the prototype has been fully assembled according to lab instructions, a minimum of 11 components are left.
