This is a homemade product from the category: “what else can be made from the parts of a broken laptop?” In a laptop, in fact, there are many useful things for homemade products. In this master class, we will use his camera. We will make it wireless so that you can look into it through any smartphone at a distance of up to 50 meters.
It will take
- Wi-fi module – http://ali.pub/5h3v69
- Boost Converter – http://ali.pub/5h3v8e
- Li-ion battery 3.7 V 550 mah – http://ali.pub/5h3vb4
- Camcorder from laptop or netbook.
How to make a wireless wi-fi camcorder
We disassemble the laptop and remove the camera from it.
In fact, this is a regular webcam with a USB interface. Therefore, it can already be used without alteration: just solder the wire with the connector and plug it into the USB socket.
We take the wifi module. It also has a USB interface. It is also a ready-made device that can be used as a wifi adapter.
We take a universal board and cut a rectangle from it.
We solder the converter to the board. We connect the battery to it through the connector. The power system is now ready. The camera and adapter will be powered by 5V.
We connect a multimeter to the output of the converter, and by rotating the variable resistor on the converter board, we achieve an output voltage of 5 volts on it.
Next, we solder the wifi adapter with plus and minus to the output of the converter.
We solder the wires to the video camera.
Next, connect the camera to the wifi adapter: “+” to “+”, “-” to “-“, “D-” to “D-“, “D +” to “D +”.
Place the camera on the back of the board. We insulate everything with heat shrinkage.
This completes the wireless wifi camera. Let’s connect the battery power to it.
On Google Play, download any P2P Camera application and install it.
Find the camera in the list by the module name and connect to it.
Let’s go to the installed application and see that the new device is displayed.
