A working self contained tube that houses a Raspberry Pi computer, cirrus logic audio card, two microphones and special voltage converter that changes 12V to 5V for powering the raspberry pi.
The tube is approx 150mm in length, and 65mmX65mm, the silicone ears self seal the ends of the tubes, fed with CAT5 cable the spare twisted pair of cables feed the 12V+ to the voltage converter, 12V goes to the microphone pre-amps, and the 5V goes to the raspberry pi. I was getting mains hum at first, but figured out how to stop that.
SR3D nature microphone
White box at present, but will be covered with a green material soon, to stop the wind noise in the microphones, and to make it blend in with its surroundings.

On test here (not 24/7 just yet) http://locus.creacast.com:9001/3dsound
The left channel is just a little noisy, so when the order of the new mics come in, will be changed to the quietest ones I have.
Here are a few other microphones I’m making
Here’s some of the fruit in the garden too
I’m working hard in trying to get these microphones out as soon as possible, for the ASMR artists and other field recordist enthusiasts that are just starting out, these are budget microphones that perform very well. You can be the judge! wear you best headphones and make up your own mind.
I’m hoping to base my working pieces of art at about £149
