Battery is not a cost effective. Not always we use micro controller. Here is a guide on Breadboard Power Supply Tutorial for all situations.Most of us need a multipurpose solution which works in most of the
Tutorial on power supply rectification. We examine several working examples with basic calculations. Fig. 1. Basic Power Supply Rectification Tutorial. by Lewis Loflin. Many devices, in particular solid state electronics, must use DC or direct current. A diode is a solid-state device that conducts in one direction only. When the anode (A) is positive and the cathode (K) is negative
In the following example I want to measure the discharging curve of a Lithium Ion battery. The battery is powering a fan. I want to know how the discharging curve of the battery look like. Therefore I measure the voltage, current and power
Build Your Own Battery Power Supply : Have you ever needed to power a project that''s not near an outlet? Have you needed to test using different voltages? Are you curious about analog circuits and power? Using Autodesk Circuits and a
0-28V, 6-8A Power Supply Circuit Diagram using LM317 and 2N3055 This design can produce a current of 20 amps with little modification (use proper rating transformer and a huge heat sink with fan). Huge heat sink is required in this circuit, as 2N3055 transistors produce large amount of heat at full load.
Guide to Charging Batteries Phases of Multi-stage Charging. When I begin charging lead acid batteries, I typically follow a three-phase method. Firstly, during the Initial Charge Phase, I supply constant current which facilitates around 80% of the recharge, where the voltage gradually rises ''s essential to provide enough current that the battery can absorb, but not so much that
A typical power supply for an electronic system is shown in Figure 1. The primary source of energy is a battery, normally an electrochemical de- vice [5]. The battery can be a primary type that is discarded after it is discharged, or a rechargeable type. As shown in Figure 1, a fully charged Lithium-ion battery supplies 4.2 volts and when the voltage drops below 3.0 volts it is
This is a dual-channel power supply powered by 6 18650 Lithium-Ion cells. If like me you don''t have lots of space, having a power supply that you can move and get out of the way without getting tangled in cables is quite useful. Inspiration
This following post tries to determine a method through which any SMPS could be made into a variable power supply for achieving any desired voltage level from 0 to maximum.
The power supply, which comes as a kit with THT type components and a PCB (so its easy to solder), takes in 24V AC supply at its input and gives between 0-30V at its output depending on user input via an onboard potentiometer. The
In this post, I will show you how to modify the UPS so it works properly. Years ago I bought these 18650 battery charge shield boards that can be essentially used as a UPS

The power supply, which comes as a kit with THT type components and a PCB (so its easy to solder), takes in 24V AC supply at its input and gives between 0-30V at its output depending on user input via an onboard potentiometer. The module is able to supply up to 3A current and is equipped with safety features that help prevent overload and shorts.

I did a lot of searching but did not find one common document which made it easy to see how to modify the HP power supply for my simulator motors. Hence I thought I would put one together with plenty of photos for anyone looking at doing this.
Time: 0:43s Here I''ve gathered some of the basic supplies needed to work with and to test power supplies, so, wire strippers, some clippers, some thin tweezers for grabbing small components. Here two silver box power supplies that I salvaged from an old PC, two different old PC''s. This one is a very old one, it actually has a 20-pin connector, and here we
In this post, I will show you how to modify the UPS so it works properly. Years ago I bought these 18650 battery charge shield boards that can be essentially used as a UPS (uninterruptible power supply). I just recently made a project that required a UPS so I finally decided to use them.

To charge the 110Ah battery bank I built, I need a power supply that can provide at least 10A at 14.6V. Since I have many old ATX power supplies lying around and the 12V rails of these power supplies are more than capable of providing 10A, I decided to modify one such power supply for using as a 4S LiFePO4 battery charger.
This is a dual-channel power supply powered by 6 18650 Lithium-Ion cells. If like me you don''t have lots of space, having a power supply that you can move and get out of the way without getting tangled in cables is quite useful. Inspiration comes from the uSupply designed by Dave Jones on the EEVblog.
So if we want 5 volts, we need at least 7 volts to maintain the steady 5 volts that we want. This power supply will not be able to convert from lower volts to 5. So once our battery is dead, our project will be too. For this tutorial, we will use a

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.
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.
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.

A lookup table for the labels on the schematic is attached under the download section. AC power source to the system is feed via the transformer which steps the voltage down to 24Vac. It is important to note that the input AC Voltage to the Power Supply Module is 24v and ensure you use a transformer which is rated for such.
To prevent battery backfeeding into the power supply when it's off, I added a Schottky diode (the two diodes in the same package are paralleled together) at the output. If you are worried about accidentally shorting out the pins, you can use some heatshrink tubing here. Here is a short video explaining this power supply modification.
