We know you've got questions, and if you're brave enough to ask the world for answers, then here's the outlet to do so. This week's Ask Engadget inquiry is from Dylan, who has the rarest of all beasts: a question relating to engineering for us all to get our teeth into. If you're looking to ask one of your own, drop us a line at ask [at] engadget [dawt] com.

"I currently own a Koyo Click programmable logic controller and I'm looking at getting a Raspberri Pi. What I need to ask you, is what would be a good and versatile stepper motor and drive combination that is both cheap (sub-$50) and doesn't tie me down to a specific hardware platform? All of my searches seem to converge to Arduino stuff that, while cool, isn't the platform I'm investing in. I know cheap motors and drives can be found on eBay and the like, but can you suggest a proven and reliable name? Thanks!"

If there's one thing we love, it's meaty questions that venture beyond asking us which smartphone you should buy. The question here is to find a platform-agnostic stepper motor and drive for under $50, so let's turn this puzzler over to you, our brilliant community, in the hope that together, we can come up with the perfect solution.
