So far all I have done is strip the RS232 level shifter and support components off the USB-serial adapter, leaving the FTDI chip behind. [...] It's easy to do, but it takes time.
I reallse you've already started on this path, for other there are a number of sources of FTDI usb<->serial cables that operate at either 5V or 3.3V including FTDI themselves.
Yes, I know, but I wanted to make it myself. It is a learning exercise as much as anything. I will buy another one and make a 5V version for my FT-817ND (how appropriate that someone else is working on that model...)
Actually, I am in South Korea. There is a cool parts website here called eleparts.com, and they do stock the FTDI modules, but I got the serial adapter at a local computer store. I cut off the plastic moulding and I am hacking on the little circuit board inside.
Best wishes,
