Bat-detector-circuit-board, back in the 18th century, it was suspected that bats navigated using sound, but it took until 1938 to conclusively demonstrate echolocation. the mechanism almost exclusively utilizes ultrasonic frequencies which are inaudible to humans.. Once you have assembled the bat detector, you can go exploring: with the completed detector, you can turn the ultrasonic calls of bats into audible sounds. you can trace these fascinating flight artists in the dark to the places where they hunt for insects unnoticed. not only bats, but also a host of technical devices emit ultrasonic sounds ..., can anyone help me translate a very small piece of code written for the 12f683 (on which the 08m is based, i believe). i'm just starting out on all this electronics stuff, so if anyone can help, i'd be very grateful..

Only 1.5" x 2", this compact circuit board greatly eases the construction of the simple bat detector. it is a high quality fiberglass board, with a silk screened component layout. the solder side is masked and tinned to aid in preventing soldering errors. this item is shipped post-paid in the u.s., having an apartment in cyprus, each evening i can see bats fly past my balcony on the way to their feeding grounds. i decided that it would be a good idea to ‘tune in’ to the bats as they flew past. the idea culminated in a bat detector that’s possibly the most refined of its kind published in elektor..
