Building the Ultrasonic Antifouling Kit from Jaycar

[bitman]

I like your soldering station, it makes mine look a real cheapie!

thx, i bought it some where in the 80s.

The cable supplied by Jaycar has been left uncut...

The cable is much longer than I expected, which bodes well for the dual unit I'm considering designing.

I'd be interested in knowing the cable length, and the size of the conductors. Do you have a micrometer or vernier/digital caliper? The diameter of a single strand, and their number would be very useful.

Also, are there any markings on the transducers - probably to late for Norman to answer!

[nigelmercier]

still do play with electronics as i'm a freelance sound engineer and also like modifiying things (like mod a scanner to make it an ais receiver)....

@bitman: this is also a project I'm considering. Could you PM me if you have any info, or perhaps a new thread (with a PM "heads-up" if you could)?

ready to start building

@bitman: I like your "helping hands" unit, where did you get it?

PS Say "Hi" to Tux for me

will do

I have bought a waterproof junction box and fitted the two switches provided by Jaycar and three cable glands into it as shown in the photo. This will be mounted out of sight below the chart table, with 12 volt supply coming from the bilge pump circuit breaker, which is always in the on position when the boat is in water, and which has 15 amp capacity, and is capable of running both units and the bilge pump.

due very busy only limited time to build, all resistors done;

Just got the letter from Parcelfarce asking for £35 so it looks like I have not had to pay any additional postage from Australia. Ordered on the 4th Jan here today, not bad. Should be able to start building this weekend.

You jammy begger!

Its an easy enough build, once you have correctly identified the resistors.

A question for Norman, I have just opened my packages and notice that the transducer has a recess in the face, did you make any provision when potting the transducer to ensure that this was filled or did you just assume that it would remain unfilled when you poured in the potting compound.
