Hi, A few years ago, I made a cheap robotic bookscanner for some out of copyright books at a library I was working with. (https://www.youtube.com/watch?v=OonuSWi9gTE) Unfortunately, I went crazy and destroyed it thinking that the "spread of information was the devil", along with the rest of my FRDCSA project. Anyway, it's like 12 years later and I'm guessing I don't have to spring for an expensive Lego NXT Mindstorms kit to do it now. Does anyone know of what would be the best way to make a portable version of this? I mean in terms of like what should I order off ebay or gearbest or chinavision or dx or banggood or whatever in order to put this together as cheaply as possible. When complete I will of course upload the instructions and shopping links and everything. I wish to ask you as you would be the most knowledgeable group I know of about this and also posting in the chat room wouldn't be seen as widely. I am willing to do like a Raspberry Pi controlling servo's or preferably like a usb controller that can run and be powered off a usb cord from a laptop. What servo's? I need something with a what do you call it discrete or click rotation sensor to make the rotations precise. Stepper motor - that's it. Secondly, does anyone know what the goto solution is for a camera (good enough to scan the page from above) that can take pictures programmatically, and upload files programmatically immediately? I'm guessing a ultra cheap true hi def webcam is the best idea, but I imagine many of you would know best in these regards. From all the stuff I've bought off these sites, I'm hoping to get away with this for under $30, but if that's a pipedream we'll be fine with whatever it does cost. I'm guessing this in part because of the price of cheap drones. Lastly, if anyone knows of some open source de-distortion software to counteract the page curvature please let me know. Or if there is already such a thing, i.e. an open hardware robotic book scanner kit. I realize that this prototype could only scan pages that were not near the front or back of the book, but even still it would be a help for digitizing all of the old out of copyright books at our library. Thank you so very much!!! Andrew Dougherty
