Putting the "Ek" in "Geek"
Digital Setting Circles
Adapting to USB…
Dec 21st
A comment that I receive frequently about my Digital Setting Circles project concerns the fact that it uses a serial port rather than a USB port. I guess manufacturers don’t typically include serial ports on notebook computers or PDAs anymore. In my own defense, USB was just coming into common use when I designed this circuit about ten years ago, and USB is more complicated and expensive to implement.

Jimbo Harris was good enough to tell me about his USB modification of my digital setting circles project. Jim found the FTDI TTL232R and was able to adapt his DSC interface to communicate via (and draw power from) the USB port.
