Re: [PSUBS-MAILIST] Hydrophones



David

I'm interested. Do you have a photo of your
hydrophone or have you not built one yet?

I love to have those plans and post them on my site, but I'd need you to explain the assembly in enough detail that the average high school student could put it together.  It would be best to take photos of each step of the assembly.  I know is a lot of work, but I think it would really be appreciated.  It would be useful to have on an ROV too.  Could you also do a beacon? 

Have A Nice Day.

Frank,
 
  I will in the weeks ahead produce the single hydrophone intended for installation aboard your boat. This is being done so that you could mount this device early with the use of the proper thru-hull fitting. It can be placed within a ballast tank and will hear thru this as long as water is present on both sides. This will not create additional drag if installed in this or likewise manner. I will set up a small process whereby many can be produced at the same time...So....
 
  Does anyone else want a preproduced hydrophone for installation aboard other submarines or for perhaps testing? Perhaps the how-to-instructions so that you could build your own?
 
  I used an all electronics preamp kit and all electronics 7watt amplifier kit and these worked great together allthough other electronics could provide equally good results. Go to allelectronics.com for ordering info. The preamp was less than $10.00 with the 7watt amplifier close to $15.00. All that is left is a small 12vdc battery and a small project box to fit it all in withy the panel controls and on/off switch.
 
  If you want to take this plunge, here is a great chance to dive in.
