So another ROV update, I did some tests of bilge pump motors as thrusters and got some interesting results
|1000gph w/ propeller
|500gph w/ propeller
These are some strange results that I need to reconcile before carrying forward, particularly the odd thrust value of the 500gph motor in forward.
Future plans involve testing nozzle shapes such as straight nozzles, nozzles with collimating fins (to reduce turbulent flow or increase laminar flow), and Kort rings. Anyone with expertise in this area feel free to chime in with comments.

So, because of the sheer expense of 6″ sch80 pipe and pipe fittings (read: several hundred dollars for a few feet of pipe and 6 fittings!), there has been a redesign!

So besides the obvious song reference, I’m starting on a new long term project (as if I don’t have enough going on?). I’m going to be building a remotely operated vehicle (ROV) with a friend for fun and potential science. This has been on my list of things to do for ages, though prohibited mostly by cost. Being gainfully employed has its benefits (ie: money).
Stay tuned for more details, as the goal is to complete construction in time for summer 2011.
Rated depth: 100m
Rated pressure: 1.081 MPa or 156psi
sch80 PVC pipe for electronics pods, 1″ CPVC pipe for frame, and aluminum for cross-bars
Internal sealed lead acid batteries
Modified bilge pumps
Pressure, temperature, compass, internal monitors (temperature, voltage, current consumption, [humidity/water sensor]). Video over IP camera
Surface control computer
Onboard microcontroller with ethernet connectivity, control via tether.
