Nicely made a DC volt meter. It can measure voltage from zero to 100 volts. Attached two cables of digital multimeter to measure voltage. I put a switch here to turn on the device. 3.7 volt lithium polymer type battery is used to run it. Which can be used up to 1 month on full charge. And when the charge is over, I have also kept the facility of recharging it. It can be charged with any micro USB cable or normal Android phone charger with an input voltage of up to 5 volts.
It has the advantage of being used for small jobs or just measuring voltage. Because large multimedia has many functions, many people cannot use it. It can be a device of choice for those who are learning or interested in working on new electronics. I will show how I made this device in today's video. So let's go to the main video. Before going to the main video, if you are new to my channel, you must subscribe to the channel.
Such PVC board will be used to make the body of the device. These boards are very easy to cut so can be cut as desired. You can use any other piece of plastic if you want. Card board can also be used to make the body. I will bring these later. Now the main device I will need is such a volt meter. These are available for purchase between 90-100 rupees online or at any electronics store. It can measure from zero to 100 volts. I am using 3.7 volt polymer type as it needs to be separately powered to measure zero to volts. Since the device will be rechargeable, the battery should be charged. I will use the TP4056 model 5 volt autocut charging circuit in order to avoid overcharging the battery. One such tip switch will be used to turn the device on and off.
Place all the components on the PVC board and take an approximate size so that I can cut it to make the body of the device. Guys I have already cut the measurements from the board to save time. Now they can be joined together using glue as needed to make the body.
At this point I will connect the two battery wires to the battery terminals of the charging module. First, connect the red cable to the positive, then connect the black cable to the battery negative. Now connect a black cable to the negative terminal of the battery output of the circuit. Solder the red cable to the other positive terminal. Battery and circuit connections are finished for now.
Now the body of the device has to be made. I will make the body by attaching the supers to the PVC pieces that I have already cut to size. Friends, once this is done, before attaching the upper part, you have to take the size of the DC volt meter and cut a small part. Cutting is done, now I will attach the volt meter here.
Now solder the negative wire of the volt meter to the negative wire of the charging circuit. Finished soldering. Now connect the other positive cable of the volt meter to the positive output cable of the charging circuit and you will see that the volt meter is switched on. Here basically the switch should be installed so that it can be switched on when needed.
