Since 2021 I have been designing and refining electronic devices and iPhone / iPad software to make bat detecting and bat recording as inexpensive and as simple as possible. You can now build very high-quality bat detectors, bat recorders and ultrasonic USB microphones for a fraction of the cost of commercial devices.
For example, if a group of 10 people get together to each build a Griff USB microphone, the total cost including cost of equipment for assembly is under £10 per person. For a pipistrelle nano the cost is under £15 per person, and the pipistrelle nano includes full Griff functionality, so is two devices in one, allowing both standalone and smartphone bat detection.
