well aqua-vu micro users i put something together! i used a medical tape roll with the inner spool and out plastic protector. a teflon tape roll would work as well. the secret is to sand down the inside spool a little so that it moves inside the plastic protector better. Cut a notch in the plastic protector and a hole that the plug for the cable can fit through to the center of the spool. if you add a little knob you can turn the inner spool (disconnect the plug )
Just need to figure a way to connect it to the micro...
