The TeensyBat site has recently released new software for The TeensyBat 4.1 bat detector.
I've been using mine quite a bit lately... This is the second one I've built (PCB Ver. 0.7). I'm planning on ordering another kit, which now utilizes the very latest PCB (Ver. 0.8). As I type this, I have the (recently completed) TeensyBat plugged into an external (powered) speaker.
I enjoy listening to the bats, using the Auto-Heterodyne feature (heterodyne with the benefit of automatic tuning).
My local bats are out, and seem to be celebrating Spring!
The latest software adds some nice features: https://www.teensybat.com/software Including very nice Auto-Record features.
Edwin Houwertjes (of The Netherlands), has recently made some new YouTube videos demonstrating his TeensyBat Detector (~ 4 months ago) - they provide an excellent explanation and overview of this kit:
Happy bat detecting!
