I'm fascinated by the design of the rewinder. Could someone provide me with some guidance on where to begin learning how to design a board like this?

- crote 3y agoIt's quite a basic circuit board. Start with an Arduino tutorial to get a feeling of hooking up electronics (Adafruit is probably a good start), once you've got it working look up a KiCad tutorial to turn it into an actual PCB. The trickiest parts here are dealing with the MCU (look for example schematics to copy, they're probably already in the datasheet), sourcing parts (Mouser/Farnell/Arrow are expensive but have good search tools - LCSC is dirt cheap but has terrible search), and soldering the PCB (stick with through-hole parts, if at all possible). You can get a bare PCB of this size made at JLCPCB or a dozen other places for less than $5 - not including shipping.

- tomn 3y agoagree, except for > stick with through-hole parts, if at all possible These days it's more work to avoid SMD than it is to embrace it. Many many parts are not available in through-hole, and dealing with 0805 passives and 0.65mm pitch ICs is not that difficult (unless you assume that it is). As a bonus, you get much easier re-work, access to assembly services, and cheaper components.
