Astável com duty-cycle de 50% para led branco alimentado por 1 pilha LR06


Maximização da carga armazenada em associação paralelo de condensadores



This simple routine selects from a set of electrolytic capacitors those that maximize the amount of stored charge in a parallel configuration.
INPUT: set of available capacitors.(capacitance and rated voltage)
OUTPUT: subset of capacitors (capacitance and rated voltage) and maximum charging voltage.



Potenciómetro de segurança


















Safety position potmeter for dc voltages. When circuit is supplied there will be no output voltage. The potmeter has to be turned into its minimum voltage position and again to the final desired voltage.
