| Does anyone have experience of a bat detector? Yes Alan I've built 3 or 4,if you can solder they're really easy not much to them at all. This one is probably easiest (that doesn't mean it's no good,it is). http://home.netcom.com/~t-rex/BatDetector.html This design can be improved by the addition of a small amplifier on its output,without that it will only drive the old crystal (high impedence earpieces)but with the amp it will drive Walkman headphones and sounds much better. Just depends on your ability to solder to Veroboard really. |
