That is my comment (XRayCam) at that link on youtube.

Small world isn't it?? LOL

I am looking into getting a ready made Ultrasonic receiver from eBay

There are 3 or 4 models up for sale...

If all else fails, I too am interested in listening to bats and the occasional multi-legged little buddies :-)

Nooooooooooooooooo!!!!   :scared:

Step away from the Buy it Now button  :laugh:

You can get an ultrasonic transducer for a few bucks online.....either new or used.   If you had an old dynamic mic,  you could replace the electret mic with the transducer.

Link to mouser electronics:

You could build one from schematics:

If you wish to build one from a kit:


I built one from a kit a couple of years back.  It works just peachy-keen.  I can hear bats clicking away.  I can hear mice - running water - rubbing your fingers together - etc.
