At the very least I think I want to offer an electronics kit, since that is the most complicated part. The rest is bearings, threaded rod, motors, stuff that is easy to get though maybe not all from one source. If I can supply assembled boards for the controller and sensors, then a user would only need to crimp some connectors on wires. I'm trying to figure out if I can make a board that incorporates an arduino, usb adapter and connections for the winder at a decent price.
I could send bare PCBs and parts for the user to assemble, but that would cut down on the number of customers because of "OMG Soldering!" . Putting together boards myself sounds like a hole I may never climb out of, so I hope board manufacturing wouldn't be prohibitive. I have an initial version which I should be able to complete when some parts show up tomorrow. It's the first board I've ever had made, so hopefully it won't be simply DOA.
I have files on Thingiverse because I can't host them on the bare bones Wordpress, so I need to find a better solution for combining files and instructions. I wanted to get out what I have so far, as sort of an alpha. If you can get the basic Winder put together, I can pass along a board so you don't have to mess with wiring up a breadboard. I would much rather tell you to crimp some connectors and plug them in, than make a detailed set of instructions for the breadboard.
I'm still trying some different things out. I don't want to drill a bunch of 90 degree nozzles, and not everyone has a drill press so I'm giving this a try-
Not everyone has a free chunk of wall either, but there are a few approaches that can be taked to make them freestanding.
