Variable power supply using LM317, 1.2V to 30V at 1A. This is the first DC power supply in my life that made to use in many projects. It is ideal for those who want to adjust voltage from 1.25V to 30V and currents up to 1A. Which is sufficient for normal use. For example, It is a power supply instead of a one 1.5V AA battery.
One of the metals wins out and pulls electrons from the other, through the outer circuit—and that flow of electrons from one metal to the other is how a battery powers the circuit. If the two terminals of a battery were made from the same material, there''d be no net flow of electrons and no power would ever be produced. That''s the theory ...

This build is made up of four subsystems. The first is the DC power supply from the battery pack, with the first filtering capacitor (leftmost C1 in the basic circuit) and a power switch (power subsystem diagram). The filtering capacitor does the job for all the regulator subsystems, so we only need it once. Next is our 9V regulator circuit (9V ...
Learn to build a battery backup supply for small electronics so you never run out of power. There are a lot of electronics that need to be reliably on all the time. Alarm clocks are a good example of this. If the power goes out in the middle of the night and your alarm doesn''t go off, you could miss a very important appointment.
UPS which stands for uninterruptible power supply are inverters designed to provide a seamless AC mains power to a connected load without a slightest bit of interruption, regardless of sudden power failures or fluctuation or even a brown-out.
