I am looking at building a Crate Beast prop this year and love the idea of making the top slam up and down. I need to do it by some type of cheap electric motor. I would like it to run on 110 but I am looking for any ideas.
Here is a link to do it by wiper motor and cam assm. I did mine with pneumatics but I got a lot of good ideas from there design. http://cindybob.com/halloween/mib/
