I want to build an electronic device that transmits ultrasound

Click For Summary

Discussion Overview

The discussion revolves around building an electronic device that transmits ultrasound, specifically an ultrasound pulse generator. Participants explore various aspects of the project, including potential kits, schematics, and the intended application of the device.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant expresses a desire to build an electronic device that transmits ultrasounds, initially questioning if it falls within the LF frequency range.
  • Another participant seeks schematics for constructing an ultrasound device.
  • A participant clarifies the intent to create an ultrasound pulse generator.
  • One participant corrects the frequency classification, stating that ultrasound is high frequency and asks about the intended use.
  • A participant humorously states the purpose is to quiet a neighbor's dog, likening it to an electronic dog whistle.
  • Another participant provides a link to ultrasonic transmitter kits found online but questions the effectiveness of ultrasound for the stated purpose, suggesting more conventional methods for addressing the noise issue.
  • Some participants engage in light-hearted banter about the neighbor's responsibility regarding the dog's noise and the feasibility of the project.
  • A participant inquires about using a specific kit to transmit sound at 24kHz, receiving confirmation that the kit includes piezo transducer elements suitable for the project.
  • There are humorous suggestions made about dealing with the noisy dog, which are met with reminders about the forum's guidelines on appropriate discussion.

Areas of Agreement / Disagreement

Participants express differing views on the effectiveness of ultrasound for quieting a dog, with some suggesting alternative approaches. The discussion remains unresolved regarding the best method to address the noise issue.

Contextual Notes

There are limitations in the discussion regarding the assumptions about the effectiveness of ultrasound for the intended purpose and the definitions of frequency ranges. The feasibility of the proposed kits and their applications is also not fully explored.

I want to build an electronic device that transmits ultrasounds (I guess that is in the LF frequency range [?]).

Does anyone know where I can find a kit that creates ultrasounds?

Or does anyone know where I could find schematics of how to build something like that?

I guess what I really mean is an Ultrasound Pulse Generator.
 
Ultrasound is high frequency.

What do you want to do with it?
 
To shut a neighbors dog up! Essentially I want to build an electronic dog whistle.

I googled ultrtasonic transmitter kit, and got lots of hits. Here's the hit list:

I'm not sure ultrasound will work for quieting the neighbor's dog, though. There are more conventional ways to do that, including talking to the neighbor. And in the end if nothing else works, at least in the US, there is small claims court where you can keep taking the owner to court and winning judgements against them. Talking to the neighbor to work things out usually works, though.

Ya, but how fun is that? I really just want to build it.

So berkeman, could I build this thing and put a speaker on it to transmit the sound frequency at 24kHz?

Nifty little widget. You don't connect an external speaker -- the piezo transducer elements are the silver round things that are included in the kit. That looks like a good starting point.

i think the neighbours are duff or they should know that the dog is noisy ...so i say u should << suggestion removed by berkeman >> tommorow morning ... isn't better lol...hey i am kiddin ... don't do it

moe, we don't say things like that here on the PF, even jokingly.
