[PSUBS-MAILIST] 12V DC Sonar Implementation

[Joe Perkel]

Steve,

I've briefly looked at this issue for myself down the road.
Hyperdrive,   http://www.hypershop.com/HyperDrive/iUSBport/  makes a wireless USB port device for iPad, I have one. Perhaps that would make the tablet interface doable.

If  PC is a must, Panasonic Tough-book is reduced scale, and both shock and water resistant. It's the laptop of choice for EMS personnel. It is pricey as a result. Perhaps it can be sourced from a guy named "Bear" at the local pawn shop?! :)

Alec, yes. I agree. My initial approach is basic old school. The tech support guys at Teledyne are very helpful and I'm sure it has been done before.  Good feedback ( I wasn't sure that email made it to the thread).
Thanks.

Note that an iPad, for instance, has a 12 hour battery so you would save space, amps, and money by getting rid of the DC-AC converter.

exercise I am noodling through. As an off shoot to developing my K-250 
electrical layout I am looking at what it would take to add (later) a 
sonar system based on a 12V DC system.  Thought I could get some 
feedback as well as provide an "example" for others considering a 
similar scenario.

In this example I used easily found components as a base reference.

batteries which are larger and heavier than I'd like (22x4x11 inches or 
560x110x280 mm and 89.3 lbs or 40.5 kg). This design gives 3.9 hrs of 
run time
