So my question is, is there an open source project that will allow me to easily get disk images over to my IIc/IIe?
ADTPro is great but I'd like something that doesn't require me to be connected to my main PC.
Thanks for any suggestions.

That's the Apple II Pi, which is basically a 6551 (same chip as on the Super
Serial Card) with a connector to hold a Raspberry Pi. I built my own
workalike, or you could use a Super Serial Card and a level converter
(something like http://amzn.to/2DSyctB) if you want to keep your Raspberry
Pi outside.

You might look at Terence Boldt's "Serial Virtual Drive" using a PI or Arduino as a HD. (select src or download bin files from the menu at left of the web page):
https://web.archive.org/web/20170629123057/http://apple2.bol dt.ca/?page=terserialdrive
Another option is Boldt's ProDOS ROM drive:

ADTPro's serial (and Ethernet) virtual drive is based on Terrence's
great work. And using a Pi is also a known solution (see
http://ivanx.com/a2server/), but I think these solutions are not what
the OP was after - trying to eliminate a "host" of any sort.

I didn't do a good job explaining what I was after. A RPi solution might work in a pinch but you're right...I'd like something that didn't require a host. Something that the A2 thought was an external floppy drive.
Something similar to the SD2IEC for the C64.
Thanks!

There is a related project from several years ago that was a
self-contained ADTPro server that could do bootstrapping as well as
virtual serial drive operations:
http://osgeld.a2hq.com/category/projects/pocket-serial-host/
It would definitely be an assemble-yourself thing, but he's got all the
project resources freely available. I have one of the units he sold -
maybe you could further his research while building something yourself.

Maybe you could make one of these, or modify the software to use on an Arduino. The firmware is linked on the page. I think Koichi is ok as long as you do it all your self (ie no support). The only issue I see for running it on an Arduino is the increased clock speed used.

Antoine might know more, but I recall hearing about Cedric having health
issues. The SPVHD is terrific gadget. I purchased a board from him years ago
and built one up myself.

It looks like this was supposed to be open-source, but nothing got released
through this page.
I tracked down source code for the microcontroller that was used and for the
manager program that runs on the Apple II:
http://mirrors.apple2.org.za/Apple%20II%20Documentation%20Pr oject/Peripherals/Disk%20Drives/Peltier%20SmartPortVHD/
That leaves the wiring. The pictures at the first link indicate that the
device is just a Micropendous-A (an AVR microcontroller with a USB interface
on a stick) with some LEDs, buttons, and SmartPort connectors wired to it.
Micropendous was an open-hardware AVR development platform (similar in basic
concept to Arduino) that was originally hosted at Google Code; somebody
mirrored it to GitHub before Google Code shut down:
https://github.com/BackupGGCode/micropendous/
KiCad schematics and PCB layouts are included, so that just leaves the
wiring external to the board. Perhaps it could be sussed out by reading the
SPVHD firmware source code, but if someone has the build documentation for
the SPVHD hardware and would like to post it, that'd definitely be
high-speed.
From there, perhaps an updated design that rolls everything into one board
would be possible...maybe something resembling a dongle that can be inserted
into a SmartPort chain and had a USB port (or maybe an SD or MicroSD slot
instead).

....toward which end both male and female DB-19 connectors would be needed.
I found small numbers of each here at about $7 each at the current exchange
rate:

I have all the wiring, construction information and firmware. Please contact
me privately and I'll arrange to get it to you. I'd rather not release it
publicly before confirming that Cedric has in fact abandoned the project.
