Thank you for your query. I appear to be popular as far as Ultrasonic hints are concerned. However, almost all of the queries I have received are in the form "I would like a circuit design, etc, etc". Whilst I am usually well prepared to help in genuine projects, I am becoming increasingly reluctant to be the "fount of knowledge" for all and sundry who are students wanting the information for their class project, which, incidentally, was due in last week and could I please hurry. If you want my help, I require a reasonably detailed description of what it is you are trying to do, what practical experimenting you have done so far, where it is that you feel that help is most needed, and how much electronic assembly experience you have. There used to be a time when experience was gained by dismantling old electronic equipment and trying to work out how and why it was implemented the way it was, then, having acquired some clues, removing the interesting "bits" and creating something else quite unrelated to the original product. I still subscribe to this view, old-fashioned that it may appear.
I would also be interested if, when you receive assistance and advice via this forum, whether you intend to make mention of it as a resource reference credit in your project description.
If you can, or are prepared to meet all the above "criteria", then please, by all means, re-E-Mail again with the sort of detailing I have indicated. I would be delighted to co-operate on exactly that basis -- co-operation.
