I have a gong from a clock I like the sound of and would like to turn it into a doorbell. I was thinking of how I would get it to strike the rods and play a few notes. I tried looking at examples but couldn’t find many. I thought that a cam system would work paired with a gear reduction system and a 9v motor. Another thought I had was using solenoids to hit the rods like in other clocks. Which would be better? I’m worried the cams would dampen the rods and muffle them.
>>2964678Check some examples online. They use a rotating drum with points that catch a spring loaded hammer to pull it back and strike the rod
It's a pretty simple setup. Some kind of iron/steel hammer, a spring, and a coil of wire that acts as an electromagnet when powered.You may even be able to buy a premade mechanism as it's what most older doorbells used.
>>2964890Here's a video of one of the3se electromagnetic chimes in operation. It just operates by powering and unpowering the electromagnetic coil.https://www.youtube.com/watch?v=vXuKfCIjQlcYou can buy one of these nutone shime replacement mechanisms off amazon for like 20 bucks. You can even get the whole kit with the transformer and buttons for 40.You'd just need to replace the chime plates in that kit with the chimes you already have.You can also maybe change the material on the ends of the strikers to create different sound characteristics.
>>2964894I’ve found some 12v solenoids on Amazon for 6 bucks, how would I wire them up to strike at different intervals?
