This is a homemade product from the category: “what else can be made from the parts of a broken laptop?” The laptop actually has a lot of useful things for DIY. In this master class we will use his camera. Let's make it wireless so you can view it through any smartphone at a distance of up to 50 meters.
Will need
- Wi-fi module -
- Boost Converter -
- Lithium-ion battery 3.7 V 550 mAh -
- Video camera from a laptop or netbook.
How to make a wireless wi-fi video camera
We disassemble the laptop and remove the camera from it.
It is a separate board - a module.
In essence, this is a regular webcam with a USB interface. Therefore, it can already be used without modification: just solder the wire with the connector and plug it into the USB socket.
Take the wifi module. It also has a USB interface. This is also a ready-made device that is used as a wifi adapter.
We take the universal board and cut a rectangle from it.
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 to the output of the converter multimeter, and by rotating the variable resistor on the converter board we achieve an output voltage of 5 Volts.
Next, solder the wifi adapter plus and minus to the output of the converter.
Solder the wires to the video camera.
Next, connect the camera to the wifi adapter: “+” to “+”, “-” to “-”, “D-” to “D-”, “D+” to “D+”.
We will place the camera on the back of the board. We insulate everything with heat shrink.
At this point, the wireless wifi camera is ready. Let's connect battery power to it.
On Google Play, download any “P2P Camera” application and install it.
Let's find the camera in the list by the name of the module and connect to it.
Let's go into the installed application and see that a new device is displayed.
Click and expand the image.
The wireless video camera is working.
As already mentioned, its range is enough for about 50 meters of line of sight, which is quite good.
