Welcome. Nice job with the custom shock mount.
"Sound Sleuth looks so simple. Is it really that simple?"
It's really that simple, and in both its PiP and simpleP48 implementations... it's really that great. Mics made with PUI AOM5024 capsules are a no-brainer as a first DIY mic set for field and nature recording. I have a few pairs. The PiP version requires no other circuitry, just connector(s). You really don't need a custom circuit board for the simpleP48 circuit; it's 1 resistor and 1 capacitor per mic, period. You can either solder the components on the back of the XLR connectors, or just use a scrap of common generic perforated circuit board.
That Instructable was authored by Jules Ryckebusch, who's on this group. Among his other Instructables is this one (), this time using directional electret mics.
You have many options for housing and mounting a pair of miniature omnidirectional mics. I will direct you to who has experimented with several different types of housings (using similar Primo EM172 mic capsules). Many of the ideas could be executed in bamboo or other natural structural materials. A dummy head out of a coconut shell?
