My mistake, the battery was in the wrong way around.

I installed Teensybat 1.3 T4.1 march052022.hex and the sampling rate can be set to 384k. However, the device now loses the time and date when you switch it off.

I built the Teensybat 4.1 with the board v0.7 without temperature sensor and without GPS and use the Teensybat41_1.3 20210920.hex. If I now set the sampling rate to 352k in the settings, the device hangs and restarts after a few seconds.

GPS is not recognized Here is the debug file.

The debug version is still installed and I still have a NEO 8 / 8M that didn't work either. But this has no USB connection, I have to install a UART to program it. It is also set to 9600 baud. Had used this to calibrate the receiver and frequency counter with exactly 10 MHz. How do I get the...

Thank you, I installed the Debug Hex and sent the new baud rate 115200, n, 8.1 to the GPS NEO 6 in the u-center. It has been recognized and shows coordinates. Autbaud showed 9600.

Thanks for the first time, I use the Teensybat_1.3 20210920 GPS TEMP.hex with the original setup without any changes. I connected the additional data line from the GPS RX to the Teensy TX1 pin 1. The GPS is still not recognized. I tested two different modules from ublox, Neo 6 and Neo 8. Both...

Kudos to all developers of the new version 1.3 .. The point to the right of the time is the seconds. What struck me, however, is that the temperature above 4 ° C shows too little. The GPS is also not recognized, it works in the Update1.1dev10april21. I haven't been able to test more than...

There is no error message in Audactiy. It could be because of the formatting of the SD card. Formatted the SD with the standard allocation unit under Windows. I reformatted it with a 32kb cluster size. So far, the error has not occurred, even with 90 minutes of recording time for testing.

The file size is well below the WAV file limit of 4 GB. For playback I use CoolEditPro and Audacity. The error does not always occur.

Sometimes with long 384k recordings on exFAT, only part of it can be played. The file size is correct. If an hour is recorded, only 23 minutes, even 46 minutes, can be played. Sometimes it's right too.

was probably misspelled by the translator, should be called "exFat".

I was just wondering, it's so okay. Great, now also supports sdFAT. Accidentally plugged in the wrong SD from the AudioMoth and everything worked.

without an inserted SD card I still have the old menu.

A hidden Easter egg, how does the reinitialization of the display work? I disconnect this from the battery when recording. So I have much less interference at 23KHz and their harmonics.

I found a bitmap on the SD card. Which key is used to take a screenshot.

I used black screws, it looks a lot better too. In the new circuit board you could also activate the second operational amplifier in order to be able to record low-frequency signals with larger capacitors. At the moment I use an external microphone with a very low-noise single transistor...

I have an infrared video camera. This records 1 second before a noise is detected. I connected this to the audio output of the detector. In "mode TE" it works wonderfully. If I then switch to "AutoREC" and there is no sound, nothing comes out of the audio output. As soon as a noise comes...

For the temperature sensor, I installed a copper sheet with the sensor drilled through on the outside. This is also how it measures the outside temperature. The GPS needs 27 mA for me. I had problems with the GPS, the audio card or the Teensy interfered with the L2 frequency of the GPS. I...

Have a new device built up and equal resistors 150 ohms as the others for GPS and temperature sensor installed. It works wonderfully. If you like this, it could be included in the circuit diagram.

Kudos to the inventors who developed this great device. Is there an advantage if you remove the 6 resistors again, possibly lower power consumption or interference. Is it possible to select and load different saved settings again? I also record bird calls via the Line In using an external...

Mein Gerät Ich habe noch einen zusätzlichen Antennen und Mikrofonanschluss getestet. Die VLF Empfangseigenschaften sind gut. Man sieht gut den DCF 60 und 77 Zeitzeichensender.

Hello Edwin, where is the GPS connected and is the code in the hex file in the current Teensybat1.0final.hex active.

so denke sollte es richtig sein.

Hallo WMXZ, ich habe die Unterlagen von dieser Seite: https://www.zachpoff.com/resources/diy-teensy-bat-detector/

Ist da ein Fehler im Schaltplan? Das Mikrofonsignal wird über R2 und C6 gegen Masse Kurzgeschlossen. C1 sollte wohl an Pin 2 des TL972.

Horn Ich habe ein Horn montiert, das ist von einer kaputten Fahrradlampe. Dieses ähnelt einem Fledermausohr und bringt etwa 10db.

Danke für die schnelle Antwort. Ich habe R12 ausgebaut und als R9 eingebaut. So habe ich ein gedimmtes Display und ich kann die Hintergrundbeleuchtung so mit dem S3 ganz abschalten, das spart schon 35mA. Das helle Display brauche ich nicht. Eingebaut habe ich auch einen 5Ah LION Akku, der reicht...

Tolles Projekt, lies sich gut aufbauen. Allerdings habe ich Mängel festgestellt. 1. Stromverbrauch zu hoch, das Display sollte abschaltbar sein, nicht nur die Hintergrundbeleuchtung sondern die Spannung des Displays. Der Stromverbrauch wird dadurch um 60% gesenkt. Wenn der Detektor über Nacht im...
