    I've been following this thread with interest because I'd love to read that ultrasonic antifouling lives up to the hype. A (cheaper) DIY system would be a great little project, so it's a shame that JayCar have moved the goalposts after orders have been placed. The postage rate above sounds unrealistic so it looks like they didn't research this properly before quoting postage to the UK on their website. It's bad for business but as a non UK company I doubt they'll be losing much sleep over it. In the absence of JayCar coming up with a cheaper postage solution (unlikely, it seems) it looks like the best way forward is a DIY system from scratch.

    Default got the first magazine article

    well i still waiting for them to respond on my email i have send them about the extra costs.

    in the mainwhile i have bought the first article and indeed that pcb doesn't look to much of a problem. may be lenseman can help us in producing pcbs? like the idea of working together and create a nice project

    ta,

    I too am still waiting for a reply. Maybe they are realising that this is bad publicity, and being seen in Australia as well as the UK. Of course they may be busy watching the cricket, and not very well disposed towards us poms.

    As an alternative to making your own PCBs has anyone considered using http://www.rapidonline.com/Tools-Fas...ource=googleps?

    The big problem for builders may not be the PCB. I have seen the drawing and it looks like a fairly simple single sided job. The difficulty may well be sourcing the correct ultrasonic transducer. One thought I have had is that it should not be too difficult for a competent electronics engineer to design a circuit board with beefier components and two outputs for two transducers.

    Producing a circuit board the old way from copper clad board and dipping in ferric chloride and drilling through the circuit printed diagram for correct spacing would not prove too difficult for most people.

    As has been mentioned above the circuits and articles are easy to download which I have just done. My problem would be:

    1. Programming the IC with the software (which is a free download as is the circuit board plan)

    2. Obtaining some parts ie the transducer

    Perhaps the answer is to just order the parts from Jaycar that we cannot source in the UK (therefore much less postage) and pay someone to program the IC
    I used to be indecisive, but now I'm not so sure...

    Some of the UK electronics mags sell the pcb separately - maybe Jaycar do the same which for, hopefully, modest cost cuts out a couple of stages in production. Checking the component list - sounds like there's a few on here capable of doing that and I could cultivate at least a couple of specialists to spot snags and maybe even to do some programming. No idea what legal responsibility is but morally I'd feel that paying for a mag download myself kept things all square.

    Well, they finally replied, offering to refund my money if I don't want to pay the extra. They ignored my suggestion to leave the epoxy out to get it under 2kg, so I've suggested it again. Maybe I shouldn't have mentioned Twickenham though.

    hi,

    let us know how you get on as it's seems a good idea to leave the epoxy out since we can buy that local
