With every one of our child i have thought about building an automatic pram rocker. Now as our youngest is a baby and has had some problem sleeping I finally decided to build one.
Windscreen wipers motors are nice with high torque and a low rpm. I bought this one from a company that strips parts from retired cars.
I figured it will come under quite some stress so i decided to make the frame out of metal. I hade some angle iron from an old garage-shelf that I welded into this lovely and sturdy frame.
I powered it up with an old laptop power source that gave 12V.
This project was incredibly satisfying to implement, and it REALLY works. Makes her sleep like a baby.
