As stated in title I am new to these projects. I am an engineering student and a life-time tinkerer, but I have yet to learn (or maybe I am to slow to) apply my learnings to this project.
I am making an automatic watch winder, for automatic or self-winding watches. Look it up on google or I explain what I want soon, but here is the basics for my project:
I have built a box; 9" wide x 8 length for the base, the height is different front and back, front is 3" and back is 7" and (if I remember correctly) the angle connecting is around 20 degrees.
All that info is so you know the scope of the area I am working with. In other words a 22" x 20" x 13" controller might be a little large.
Now in the angled face of the box is 2 holes (about 3" diameter) and I have 2 circular platforms for the watches to be attached to (don't worry how I have that worked out). The platforms will sit inside the box at the holes and rotate very slowly; 5-10 RPMs is optimal 20-30 RPMs is acceptable (I guess... ).
Here is the problem:
I got few stepper motors for cheap (specs here http://www.surplusshed.com/pages/item/m2015p.html), but I don't understand and have been unable to find much info (at least info I fully understand) about stepper motor controllers, drivers, and programmers.
I am guessing I need a controller that will control at least 2 steppers, has internal memory, so once programmed it can run without a computer, and is small enough to fit in the box.
My wants:
I would like the platforms to rotate clockwise for 30 minutes, then rotate 30 minutes counter clockwise, stop for 2-3 hours, then repeat the steps indefinitely; unless powered off, but when powered back on it will go about the program. Approximates are ok. Also, the cheaper the better. Recommendations are always welcome, actually that is why I asked.
What I have:
I have a box, motors, wire, solder, variable dc power supply, a radio shack down the road, credit card for the internet purchases, various hardware, tools, and other parts from computers and random devices.
If I can build the controller and programmer for cheap, that is fine I have plenty of time. Please do not assume I have anything; I know I need a programmer and maybe a controller and/or a driver. The real help I need is a better understanding of how to control stepper motors and what products I need and what those products do. Most info I have found assumes you already know how to much of this. I need a book like, "An idiot's guide for dummies that are stupid and slow... and look funny", maybe that is too niche of a book.
Anything you can do that will shed light on this for me would be wonderful.
If you might be able to help, even a little, please post. Also ask any questions if needed.
I will post pictures and maybe video of completed project.
