A quick note on the van #BattyBirdPi: My custom waterproof case for the #AudioMoth worked just fine, including the experiment with using a PTFE membrane for mushroom cultivation to keep water out while still letting sound in. This is (more or less) the same material as the Gore stickers that come with the waterproof case, just bigger.

The one thing that I did just notice is that 3 of the 4 case screws fell out - yikes! Time for some threadlock on those...

I have the #battybirdpi semi-permanently mounted on the roof of the van now, and am enjoying that it's picking up birds continuously. I ended up just mounting the microphone and running a long-ish USB cable to the #raspi inside.

I do still have to update the GPS coordinates manually, something to automate in the future.

While driving, it does correctly note that the main noise it hears is 'Engine'!

Today's #mayke (22/30) is another episode of "let's put a Pi in an enclosed box and put it in the sun".

This time it's a #BattyBirdPi, designed to detect and classify bird calls during the day and bat calls during the night with an AudioMoth microphone that goes waaaay up to 384kHz.

It's in a box with a magnetic mount, but this time designed to only mount on the van when parked, rather than while driving.

The microphone is protected by a splash-resistant sticker on the inside.
