An idea that comes to my mind to swing a baby swing automatically is using a CD drive eject - close function , I have several such Drives I dont use and I dont want to use a computer to do the periodic control eject \ close. Can it be done without a controller or just a simple circuit? Also, are there any other ways to make the swing automatic , what I need is just a back and forth motion to couple it with the swing?
Here is the typical swing:
Also we have a rocker like one below can it also be automatized?
Note: Some babies wont just sleep unless they are swinged\rocked continuously hence the question. And I know automated stuff is available but we already have these non automatic stuff.
I had asked a similar question here
