$2 for 2-Layer PCBs & $5 for 4-Layer PCBs: [ Ссылка ]

In this video, I am showing how to make Simple adjustable voltage regulator circuit using lm338 voltage regulator, that can be used as mini lab bench power supply or any battery can be charged, so can be also used as a battery charger for any battery.
Input can be taken from 24-30 volt 5A SMPS, or transformer based power supply can so be used, It is also equipped with the voltmeter for displaying output voltage, This is very simple electronics project idea, you can do at home.
