For a few years now we have had bat which regularly flies round the garden, Googling about bats I came across a bat detector circuit from  Tony Messina.<\/p>\n

Tony’s site (http:\/\/pw1.netcom.com\/~t-rex\/BatDetector.html)  is packed with interesting information and a link to the UK where you can buy the printed Circuit Board if you didn’t want to use veroboard.<\/p>\n

The PCB is from Lee Rogers (mail: lrogers222@hotmail.com) in the UK for \u00a35 including p&p, the majority of the parts are available from Rapid Electronics<\/a> , things out of stock at Rapid can easily be found on eBay.<\/p>\n

UK parts list Rapid<\/a><\/p>\n

The testing and adjustment was done by pointing at running water or rattling keys and tweaking the volume to a comfortable level as you go.<\/p>\n

The total cost of the project was \u00a328 and took about an hour to construct.<\/p>\n

\n

\"SAM_5686<\/a><\/p>\n

Just got to test it on the real thing now \ud83d\ude42<\/p>\n

Update  <\/strong>12 August 18<\/p>\n

Well it took a while for Norma the bat to pay us a visit, but she did and the detector worked just fine, very impressed with it \ud83d\ude42<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
