i have a school bell that i got from my old high school righ after i found they where kicking me out and i was gonna rig it to work as a car prop to drive around school and ring it thats over, NOW BACK TO THE QUESTION i have a job now at a shop and its noisy and we cant hear the phone i wanted to know if ther was away of hocking up to the phone line to make it ring when the phone rings the bell runs at 24v but ive tried it with 12v work but not as loud i think it can handle as much as 30v help
ohh i see but in that cuircut ur using 120v and how do u power the ring detector also i looked for some of the component but cant find a store that has all of them noob needs help
The circuit will switch whatever load you want via the relay. It can handle 24V if you use a regular mechanical relay.
The 5V to power the circuit can come from any standard power supply. It's fairly easy to find 5V power bricks at surplus stores these days so that would be my first choice.
conecting big bell to ringer
