Got less complex design, just google around.

got lah but i too lazy to mess with it. in china (from aliexpress, etc) can find those wav/mp3 doorbell. then you put your own file in it, tada....
but problem is my wiring is 240V, need to think about where to put the transformer etc

I dont mind something like this - I want only the mechanism to pull the bell. I dont want the bell. I want to use my wind chimes and attach to the puller/control unit
Any ideas? like some kind of servo

Use servo motor

ah! thanks. now where to find?

Get that aliexpress wav/mp3 la.

Powersupply easy la. Just get the switching powersupply. Wire 240v in. Than joint the dc wire to the board. That's all.

The chimes also not difficult. Either use A DC vibrator motor or solenoid.

Vibrator motor -> https://www.aliexpress.com/item/UXCELL-Rate...2d-d5cac3c2b106

Solenoid -> https://www.aliexpress.com/item/Hto-0420L3v...c5-8eb50aa6e6be

Parts you need,
1) powersupply 240v-> 5v/12vdc
2) Vibrator motor or solenoid
3) switch
4) casing.

You need learn the arduino prg and board before able to DIY.

Not for normal people.

Buy the ready make.

You should know my DIY skills not good la
I sked burn down the house
my boss will fry my sotong 😭

You can also get a normal DC motor, spring load it. If you don't have, the motor shaft will not "park" back.

For non Arduino savvy, best is get a simple motor, spring load it, but this need some mechanical work.

Nah



No fried sotong. No electrical. No fire.

Classic look too.

That vibrator motor is simple enough. Press the switch and activate the motor. That counter weight will hit the spring or chime in high speed. Create the shaking chime.

Nothing much mechanical work require. A bracket to mount the motor and chime together.

Teh tarik on you.

Nah

In second thought, I prefer starbuck latte.

Don't come and complain still no door bell.

I wait a few more years then complain

Want to know that if I can convert doorbell point with 4 wires to a wall socket. Instead of using it for doorbell, I want to use it power up an IP security camera.



How to rewire the wires to the wall socket?

Thanks in advance.

i still no door bell

Ur door bell point should have 5 wires no?
Earth, Live, Neutral, and 2 wires that is from the doorbell switch

the Live should be line voltage so as long as you have that, and earth and neutral u can wire it to become a socket.

But my doorbell point doesn't have the plastic box so even if I wanna convert to a socket I don't have a place to screw the socket onto, unless I drill and use wallplug.

Yes. 4 + 1 Earth.

I understand that no power goes to the doorbell if doorbell switch is not pressed. Correct me if I am wrong.

So, do I need to rewire the doorbell switch too?

Thanks.

that's not entirely true, actually there's a set of line voltage (220v AC) coming into the door bell unit itself and that is permanently powered. The door bell unit itself has a transformer which steps down to lower voltage that goes to the door bell switch and then back to the solenoid for the actuator

In other words, the door bell unit is always powered all the time, just that the solenoid which controls the door bell actuator (within the doorbell unit itself) doesn't get powered unless u press the switch, so touching the wrong part in the door bell unit will actually get u a shock eventhough the door bell is not pressed.

here's a pic for better illustration, it's from an older post here in LYN as well


here you can see that the AC part is always powered, so what you need to do is just connect the AC power's Live and Neutral, and the earth wire, to ur 13A socket. the wires coming from the doorbell you can ignore them, wrap with black tape or something.

In fact you can even loop the AC power source to a 13A socket and still keep the connection to the doorbell unit (so you get both). IP camera don't think will use a lot of power so it should be fine to loop.
