I actually looked at putting an STM32 chip with USB OTG on a board in
one of those 25 pin hoods, though I was looking more at plugging it into
the parallel port for the TDock idea I had / have.

John,
Fantastic idea. My thoughts would be to house everything in the DB25
hood and instead of having a cable hang out it it, just put a Micro or
Mini USB jack. That way whatever device you want to attach to can just
hook up to it with a standard USB cable. A MUCH cleaner solution than
piecing everything together.

I'm still investigating Bluetooth options. Amazon's Bluetooth to
rs232 options are pretty pricey for finished, packaged devices.
Raw circuit boards are cheaper but then I'd have to make my own box.
Seems like we need a custom cable. It would be nice to have a cable
had USB OTG, USB Serial, DB25, and proper full-null wiring all built
into one cable. They make the FTDI chips pretty small. We'd also need
a small PCB and the FTDI chip surface mounted to it.
Even if we kept the "OTG" feature separate I think this would be
really neat M100 peripheral.
One could use a glue blob to protect the components or for a better
look 3d print a shell. 3d printers are becoming pretty common we could
print some batch of custom cases. A work friend has offered to print
me some parts to make a 3d printer, I will give it a shot if that ever
comes through.
