I found the charger and manuals for the old pinger while cleaning the room. We are currently testing a much smaller, more efficient pinger that was designed by miguel and myself, however we are waiting for parts. For now, someone needs to solder the piezoelectric back onto the old pinger board, charge it, and test to see if it transmits signals. You can either use the hydrophone system on Polaris, or create a receiver circuit on a breadboard.
