Un condensatore elettrolitico da A 100uF, a conduttori radiali, tarato per almeno 35V.

For an electronics enthusiast, having a 5 volt DC (direct current) power supply available can be very useful.Many operational amplifiers, microcontrollers, and other integrated circuits (ICs) do require a 5-volt power supply (although most can operate in the 3-15 volt range).This article describes how to build a simple 5V DC power supply, capable of providing a current of up to 1.5 Amperes.You will need to solder various components together.
