[PSUBS-MAILIST] Digital Depth gauge with secondary display to passengers

[Jon Wallace via Personal_Submersibles]

You'd have to convert the output to voltage then measure it via a 
microprocessor such as the Arduino but possibly with a higher resolution 
ADC than is native on the Arduino.  Then it's just a matter of choosing 
the display type, either LED, OLED, or LCD. The embedded display on the 
sensing unit must be in BAR, you usually want feet or meters.  You've 
got a learning curve if you aren't familiar with hobby electronics but 
check sparkfun.com and adafruit.com for supplies and resources.
