Can you use a lead-acid battery as a power supply?

Using Autodesk Circuits and a lead-acid battery, you can create a circuit that will act as a variable power supply, outputting a range of voltages from 5V to 20V. After creating the power supply you could drive motors using variable voltage, power microcontrollers, logic circuits, LED strings, analog circuits, and much more.

Can I use a battery if I'm using a power supply?

When powering it on for the first time, use a power supply if you have one. Limit the current to 3A. This will keep everything from blowing up if something was connected wrong. Once everything is working using the power supply, you can use the battery. I would highly recommend adding a switch in-between your battery and the circuit.

What can you do after creating a power supply?

After creating the power supply you could drive motors using variable voltage, power microcontrollers, logic circuits, LED strings, analog circuits, and much more. This is a good way to learn how basic electronic components can be put together, like a puzzle, to accomplish a task.

How to make the power supply fully automatic?

To make the supply fully automatic, we need a duplicate of the Power-Switch, and use that to remove the battery power from the DC-DC convertor when the Pi has been made powerless. Otherwise, the batteries will be drained by the power requirements of the DC-DC convertor and all the logic.

How do I test a 5V power supply for RPI?

The switching mode regulators like LM2576 and others usually have a shutdown pin, which can be used stop and restart the 5 V power supply for RPi. For testing I would recommend loading the supply with a power resistor of about 2 ohms (about 2.5 A current) for several hours. If the supply survives that test it will work fine with RPi.

Should I buy an ATX power supply?

As the web based tutorial on Electronics Tutorials shows, an ATX Power Supply provides a whole host of different voltages and quite a bit of power. Also take a moment to remove any fans you find in the case of your old PC. Those will be great later for blowing air and keeping your power supplies and other electronics cool.
