Battery Eliminator With Voltage Regulator (2,4,6,8,10,12)

Introduction: Battery Eliminator With Voltage Regulator (2,4,6,8,10,12)

This instructable will help to make a battery Eliminator i.e., we can split or reduce the high voltage to required voltage and maintain constantly

Step 1: Collect the Required Items

The required items are
1-Voltage regulators(2,4,6,8,10,12)
2-12 v adapter
3-12 v jack
5-Card board
6- Wires
7-Rotary Switch
8-Soldering gun
9- Some solder

Step 2: Theory

Voltage regulators are nothing but which regulates the voltage constantly
It has three pins
1- input
we have different voltage regulators for different voltage we need

Step 3: Making

Make the connections as shown in circuit Diagram
on a PCB if available or else any thin wood. I have used a card board to connect and to build the circuit


your battery Eliminator is ready as u switch from one point to another the voltage is going to vary and will be constant

if you like my instructable please like and follow me for the out put video

Thank You. :D

    A good use for salvaged regulators, but for the 7812 to function properly isn't the input voltage supposed to be higher than the 12 V. supply your schematic shows?

    Ya but with this we will get constant voltage

    Now i hve changed the circuit
    You can follow that

    Thank you for supporting

    Hi, just one point, the wiring diagram you drew makes absolutely no sense, it will not vary voltage or even work the way you have drawn it.

    This is a great tool. It is really convenient to have a voltage regulator at these values.
