Raspberry Pi Bat Project

To avoid that nice acoustic bat work is limited by the budget of the user the developers aimed

to create a "low"  budget bat detector with high quality acoustic features.

Core of the Bat Pi, is the Raspberry Pi, founded in Great Britain. This minicomputer scores with its very low price, while the compactness fits for outdoor work. Changing  some software features and adding available hardware every application center on the Raspberry Pi, the WLAN, SMS, GPS and Network with a central server (Bat Pi Cloud). The flexibility is overwhelming.
To compete with expert systems a commercial standard USB-microphone, Dodotronic Ultramic 250k, was choosen.

The nonprofit project is supported by nature conservation organization (NGO) Naturschutzbund Deutschland (NABU) Landesverband Nordrhein-Westfalen e.V. (Germany).

To stay at the state-of-the-arts the modular system is a good choice.

Change the innovative components and  the system is up to date. You can as well use single components with other devices. If you want to hear and/or see the recordings, connect the USB-microphone to a tablet.

The project shows that the plug and play mentality, which is announced for compact detectors, is not preferable.

Like the user of the Bat Pi every acoustic bat worker should know the technical background of his recording tool,

the meaning of the settings and the correct choice concerning the recording situation, the information, which could be extracted from acoustic data and the limits of the method, the microphone, the classification and the analysis.
