[DIY] Use mosquito repellent to modify wifi repeater, wifi signal booster [Copy link]

Many families have WiFi, but inevitably there are some places in the home that cannot be covered (places with poor signal). Today I use 8266 to DIY a WiFi repeater. Today I will talk about the method first, not the performance, which I will talk about later (I will test the performance specifically later, welcome to pay attention).

Relay schematic diagram:

Material:

1. Mosquito repellent housing

2. 220V to 5v module

3. (USB to TTL, for flashing)

4. esp8266 module:

First, you need to flash the firmware for the 8266 module. Here is the ttl flash connection diagram:

This is the esp8266 flash machine I made using a breadboard:

Then use the esp8266 flashing tool to flash the AP firmware. The configuration is as shown below:

Attached flash tool address: https://github.com/OpensourceBooks/esp8266-AP/raw/master/ap.zip

Then connect your phone to the MyAP hotspot:

Enter 192.168.4.1 and you can set it up happily:

• Note, set the wifi that 8266 will connect to in STAsettings. Do not check Automesh, then click the Connect button.

After a few seconds, it will return to an inaccessible interface because esp8266 will automatically restart after setting up, and the page will be disconnected at this time. At this time, reconnect to MyAP hotspot, then open 192.168.4.1, and set AP settings (8266 wifi, the phone needs to connect to the repeater, which is 8266).

After the same setting, it will return to the inaccessible page. Then you can connect according to the wifi hotspot and password you set.

But when using it, it is not very (very) beautiful to plug it into the breadboard. So, a case is needed. The mosquito repellent is now available:

Take it apart and there's plenty of room inside:

Now you need a 220v to 5v step-down module and a 5v to 3.3v step-down module, because esp8266 uses 3.3v. Solder them to esp8266:

Without putting on the case, plug it directly into 220V and try it. The phone can access the Internet:

Finally, put on the lid and you are done! The final effect:

Nice idea

Looking forward to the performance review. It is really annoying to be in areas without wifi coverage. I can’t even watch a drama!

Summer is here, and this thing is quite practical!

This is possible. I really thought of using the mosquito repellent board as a relay. . . Good idea
