Duwayne KV4QB has been playing with an Arduino Pro Mini and a small OLED display to use as a stand alone replacement for a analog meter. The existing Raduino in the µBITx does not have sufficinet spare analog input pins to provide everything that Duwayne wanted to measure.
More information can be found on his blog at:

He is also working on a small board to provide forward and reflected power readings for SWR metering and power measurement.
This has created a bit of interest on the list, and represents an interesting idea that is potentially adaptable to other projects and use cases.
