Okay guys I am a complete ignoramus when it comes to electronic circuits. I can wire a bathroom. However when you start talking resister, mosfet, cap, pot and all these things my mind goes numb. But I have this project that I really desire to finish and I need some real help. I sure wish I had an electronic geek friend to pick his brain but I don't. I found this forum and you guys seem to have way more knowledge about this stuff than I can imagine. I am trying real hard to start understanding this stuff, but just give it to me as plain as possible and I will try to not ask too many stupid questions.
Anyway here's my quandry.
I am building these bird decoys that will have spinning wings. The wings will be powered by these low draw motors that I would like to power from a 1.5vD battery and hopefully have it last a long time. The motors work fine with the 1.5v, but can handle more. I think they will last a month of continuous use on one D battery. Okay here's the tricky part. I would like to have these motors kick on for a short while then be off for a short while. Exact timing is not important but for reference lets say on for 30 sec/Off for 30 sec. Or even on for 20sec/ Off for 60 sec. I want to have a multiple of these so some are always coming on and some are going off. So far what I think I need is a multivibrator of some sort, but when I look at schematics of these all I see is Greek! Plus I don't have any idea what would work with my voltage requirements. Looking into the Multivibrator it seems that I could build an Astable and have it switch back and forth between two motors? then one circuit could be used on two of the birds?
So can anyone help me out? I would like to keep it as simple as possible. Thanks ahead of time.
