I have a bit of a strange question. But is it possible to somehow display the hashing process onto an external display?
What sort of display did you have in mind?
The bfgminer api exposes most of the useful information so I suppose something like attaching an Arduino with a 7-segment display to the USB port and having a script to feed it for example the hashrate from the api could be one simple option. Replace that 7-segment display with some commonly used small OLED and you could fit a little bit more info there. Replace the Arduino with a ESP8266 or ESP32 and it could read the bfgminer api by itself without needing to be attached to the USB port.
Im not sure what sort of display. Im researching different options now. - But Im wanting something small, probably around 4x6 inches or so. But I believe ideally, Im wanting to display the command line process?
Not for any functional reason. But rather last night I had an idea to make sort of an art piece out of an Apollo. And I think displaying the code/hashing on a external display a requirement to make it worth exploring this little side project further.
