[GreenKeys] Usb adapter

[ad7i]

I don't have exactly what you are describing, but I've been doing a lot of
PCBoard layouts for things that include USB to serial converters and
microcontrollers. My most recent task is an electronic selector magnet
driver (meaning it doesn't have a high voltage loop per se, but instead
uses lower voltages (and small limiting resistors) to get the magnetic flux
up to full value in a couple of milliseconds).

If Greenkers were willing to come up with a set of requirements (fewer is
better than more) I think I should be able to come up with a simple PC
Board that functions as a USB to HV Loop interface with ASCII to BAUDOT
conversion included.  PC Boards fabricated in China are surprisingly
inexpensive.
