Xiaomi wireless switch doorbell

This is a case for wireless switch of xiaomi with name tag (name tag create with white filament to let light pass it). It's designed to cover old doorbell and use the light of old doorbell for the nametag. I use a wireless camera by xiaomi outside so when somenone push the switch button the hub makes ringing noise and a notification comes to my phone, then i open the camera and see who it is and speak 2 ways with him (camera cost only 15 euro and switch 10) so i have smart doorbell for 25 euro. I got power for camera from outside lamp using a sonof smartswitch i can open and close the light having the light switch always open for the camera.
To make the nametag just write on top your name and cut it leaving only 1 or 2 layers from the back so the letters don't fall and the light will pass from thin layers creating a nice effect. (small area is front, large is back)
