But, the park is huge and full of people. Just drop by a supermarket nearby and pick up some standard batteries to recharge your phone on-the-go. Click here to see where you can get everything you need to build this circuit. The circuit is based around the LM chip. The circuit will work perfectly fine without these also. The resistors R2 to R5 set the voltage levels on the data lines to specific voltages. These voltages ensure that the device knows what current to use for charging.

I got the values for these resistors from an Adafruit article where they opened an iPhone charger to see how it worked. These values will make an iPhone and many other devices charge with mA.

It also reduces the voltage by 1V, which means you need at least 8V in for the charger to work. Also, it makes it possible to use a DC socket for connecting a range of different inputs without worrying about plus and minus being correct. The voltage regulator can still get too hot and shut down, even with this diode.

If you find that this happens a lot, you can solve it by adding a clip-on heatsink for TO All these batteries are fairly simple to find in most supermarkets. This circuit is fairly easy to build. You only need 7 components. If you want to use a different type of battery, just switch to a different battery connector.

Or even better, use a standard DC input socket so that you can connect it to standard DC wall adapters. You can also use solar panel chargers on a sunny day. Thank u for the article. However, the should not be used due to the heat it outs out. Try a MC chip instead. I suggest for beginners because it makes the circuit pretty easy to build. I suggest using a usb-socket with cable, then you can plug the wires into the breadboard. I think u ihave all components but for the in my couple of boxes of starter kits.

Did your circuit work, because I tried to do it on a breadboard and only the LED work, and i dont see my error. So, I was wondering if you had a photo of your circuit so I could see where my mistake was. As you mentioned that It is really not necessary to use rectifier diode. Please let me know is i am Right or Wrong? Hey Jagjot, For this to happen, the input battery voltage would have to be lower than 5V.

Could be. But, the third thing is that the charging circuit inside the phone would have to be designed in such a way that it was possible to get power out of it. In case of otg capable phone. What you think??.

It will reverse charge unless the battery voltage less than phone. But dont let to be happend.

Let's learn more. I had heard that one must use extreme caution when placing the oscilloscope probe earth of this and any oscilloscope on the test circuit if that test circuit is also brought to mains earth potential by plugging it in to a USB port to power it. An example of such an isolator is shown here:. A less costly alternative to many of the other the eye-wateringly expensive isolators also shown on EBay might be really useful. However, tt seems to be a difficult circuit and I don't think I would be able to design this one.

Let me try, I'll let you know if I happen to crack it. I finally tracked down a schematic of the isolator. Unfortunately the one given to me was small and not clear. Tried to sharpen in Photoshop but it is still poor. It will give you an idea. It's a good choice for appilcations that isolation is needed between PC and peripheral device.

Sir i want to charge my andrioad mobile by usening 3.In this post we will try to analyze a few interesting IC LM based power supply circuits and related application circuits which can used by all hobbyists and professional for their day to day electronic circuits and experiments.

The following circuit examples simply depict few of the very interesting useful power supply circuits using this IC. The first circuit shows the typical wiring format done around the IC.

How to Make a Bench Power Supply

The circuit provides an adjustable output right from 1. This circuit produces an output that may be equal to the input supply voltage but the current is well regulated and can never exceed the 5 Amp mark. R1 is precisely selected so as to maintain a safe 5 amp maximum current limit that can be withdrawn from the circuit. The IC LM alone is specified for handling a maximum of 5 Amp of current, however if the IC is needed to handle higher currents, in the region of 15 amps, it can well be modified to produce that much of current with the appropriate modifications as shown below.

The circuit utilizes three IC LM for the intended implementations with output voltage that's adjustable as explained for the first circuit. R8 is used for the voltage adjustment operations. In the above designs, the power supply utilized a pot for implementing the voltage adjustment procedure, the below given design incorporates discrete transistors which can be digitally triggered separately for obtaining the relevant voltage levels at the outputs.

The collector resistance values are chosen in an incremental order so that a correspondingly varying voltages can be selected and becomes available through the external triggers. Other than power supplies, LM can also be used as a light controller. The circuit shows a very simple design where a phototransistor replaces the resistor which normally acts as the component for adjusting the output voltage. The light which needs to be controlled is powered by the output of the IC and its light is allowed to fall on this phototransistor.

As the light increases the value of the photo-transistor decreases which in turn pulls the ADJ pin of the IC more toward the ground, forcing the output voltage to decrease which also decreases the light illumination, maintaining a constant glow on the lamp.

The next circuit shows a super simple wiring with the IC LM whose ADJ pin is connected to the output after a current sensing preset. The value of the preset determines the maximum amount of current that becomes permissible through the IC at the output.

The circuit below can be used to charge a 12 volt lead acid battery safely. The resistor Rs may be selected appropriately for determining the desired level of current for the connected battery. R2 can be adjusted for obtaining other voltages for charging other categories of batteris.

Some sensitive electronic circuits require a slow start rather than the usual instant start. The inclusion of C1 makes it sure that the output from the circuit rises gradually to the set maximum level ensuring the intended safety to the connected circuit.Hey Guyz, This time I'm making a variable bench power supply.
