Complete working unit (Teensy 4.1)


Yes, this one is finished.

I usually do not sell finished detectors so this could be your chance to get one without building it yourself. I had some materials stocked and I can use the money very wel at the moment so I decided to build one.

I built this one without any options installed, except for the 16MB audio buffer which allows you to store a few seconds of audio before actually starting the recording.

(i did do the battery monitor modification)

It is fully functional, ready to use, with built in li-po battery of approx. 5Ah.

It does not come with charger (standard USB-C) also no headphones and no micro SD memorycard. (SDHC class 10, 32GB or less) (larger memory cards can be used when formatted to FAT32)
