Awesome Project and cheapest DIY I've found
For SmartPortSD Apple II PCB
This is the cheapest (~$20 for everything) solution I've found to have any kind of emulated storage device for an Apple II. I've never done SMD soldering before, but I was able to get it done by hand with a small iron and a hour or so. Figuring out all the parts was honestly harder, so here's the Digikey cart I put together for 5 devices.

I got the wrong switch, so here's the correct one:

I hope that helps someone. My device does work except for the LED, so I'm not sure what's going on there, but I'm pretty sure it's something I did, but I don't care about it much. I'm getting a hot plate to try to build the rest.
