Re: Connecting existing Doorbell (AC door bell with bell switch ) to raspberry pi 3 GPIO

What sort of bell is being rung by the doorbell?? IF its a mechanical bell and hammer you may be able to wire a passive circuit using a magnet superglued to the bell hammer with a reed switch or similar to detect the magnets movement and ringing of the bell.. same result but no need ti get involved...

Re: Connecting existing Doorbell (AC door bell with bell switch ) to raspberry pi 3 GPIO

It's the same in North America as well, full AC voltage is just too dangerous to pass through a flimsy plastic doorbell button exposed to the elements. It's 16 VAC here too. I'm not sure where the OP is, but they almost certainly have a transformer somewhere. https://diyhousehelp.com/doorbell-wirin...

Re: Connecting existing Doorbell (AC door bell with bell switch ) to raspberry pi 3 GPIO

I’m really surprised that the doorbell would be at mains voltage. Are you sure there is not a transformer dropping the voltage to 12v? You can't have an outdoor bell push at more than 48V (SELV) there'd be too much risk of electrocuting the postie. My doorbell runs at 16V AC. It's the same in North...

Re: Connecting existing Doorbell (AC door bell with bell switch ) to raspberry pi 3 GPIO

Yeah , the doorbell works at main voltage and there is not any transformer or any other device dropping the voltage , am guessing there might be something like that internally in the bell. Guessing when working with mains voltage is a sure way to get yourself or someone else killed or to start a fi...

Re: Connecting existing Doorbell (AC door bell with bell switch ) to raspberry pi 3 GPIO

Standard "AC voltages can be dangerous, only work with them if you are qualified" warning. A relay would likely be the most suitable. You'll need to find one that works with the voltages output by the doorbell circuit. The relay's coil should be connected in parallel with the doorbell and you can u...

Connecting existing Doorbell (AC door bell with bell switch ) to raspberry pi 3 GPIO

Hello, (Total noob question, avoid my stupidity if any) I am planning to make a smart doorbell which is connected to an already existing normal AC powered doorbell system (just a bell switch and a doorbell) , I want to connect the wire from the switch to both my bell as well as the GPIO of my raspbe...

Re: Using the pi 3 as NAS

Thanks for a quick reply.....does a power supply unit for a desktop pc do the job?

And could you recommend any universal sata to usb converters

Using the pi 3 as NAS

I am planning to use a raspberry pi 3 as a NAS, I have 3 2.5inch internal hard disks and am planning on buying a 3.5 inch internal hard drive . will it be possible to use a power supply unit to power up the hard drives and connect all of them to the pi using sata/ide to usb convertors?. 2x160gb inte...
