      Hi Sam, DId you look at the specs of the audioshield ? https://www.pjrc.com/store/teensy3_audio.html That tells you all about how this works. We use the SPU0410 in conjunction with that board. cheers Cor

      Hi, A few days ago we got a report from a user that had issues with version 1.7. The issues were related to the resulting wav-file behaving different in Batexplorer. It turns out that this was due to the newly added option to use a serialnumber...

      There are lots of examples around on the forum. Just study those. You can study the code of our bat-detector (V1.6 code is available) but thats tailored to a very specific design . Look at the beginning of this thread to see a more "down to...

      I have no idea how that would work, the audio-shield is needed (as far as I know) to convert incoming audio signals into the digital domain for processing. But you can search the forums to see if anyone has allready done that. The audio-shield...

      We have been using this microphone for several years to listing to bats and they work fine. We have clean recordings using these.

      Hi, I have no experience with PDM microphones and their usage. I see you use an example library from frankB but I have no idea how he used that in a real application with ultrasonic sounds. The microphones we use in our batdetector also use...

      Hi Krzysztof, Thanks for those follow-ups. I just now see them because a new entry in this thread was not automatically send to my mail-adress. On #2, the odd thing is that we have not changed that section during the update. The battery info on...

      Hi Krzysztof, Thanks for that report. On the battery, the % is read directly by the hardware and based on the changes (drop in voltage) TB estimates the time "left" in the battery. But your screen indeed shows that the hardware reports the %...

      Hi, I am currently holding the source code until its clear that the code is without issues. And if you are interested in the code, maybe you can share what you would like to change in the code. The code of v1.6 has all the "crucial" algorithms...

      The new update will allow adding a prefix to each recording to recognize individual TB-machines allow using the last stored GPS location in recordings without having the GPS active (saves batteries in deepsleep) allow the user to directly go to...

      Hi Edwin, Your wish is ... possible. I allready have a sunrise/set code onboard but it needs some testing. cheers Cor

      Hi Grizzly, That is simply too far fetched for this processor. We have experimented with a "crude" approach to recognizing species by looking at the peak frequency, rythm etc but this did not give a reliable output. We could - but I wonder how...

      Last year we worked on a clearer visual overview of the functions of the buttons on the Teensybat but never shared that. I have attached the V1_6 version for reference.

      Hi, I am about to start updating the code to create V1_7. Currently on the wishlist are: - optionally add a prefix to each recording to recognize individual TB-machines - restore last recorded GPS position in deepsleep to allow recording without...
