Calibrating the CMD and project update by Jeffrey

For those of you checking in for the first time; De and I are working on an unmanned instrument that will collect tidal energy data, current 
measuring device (CMD). Based on our data we will determine if tidal energy is a viable alternative and renewable source of electricity.  

The accelerometer ( aka Hobo) fits into the center swing arm; which, after deployed measures the tilt in degrees.

Water current was measured using the Hack 950 Flowmeter.
The flow rate at this location was 0.63 m/s.

We tried a variety of locations; flow rate varied from 0.63 to 0.57 m/s. 








The next step was to bring the Hobo home and download the data...........For this experiment I set the data logger to record ever second. Yes! I have a lot of data for De and I to go through.
