Been playing with the idea of putting an IPA in a more low profile housing.
There's not a whole lot in the case, and it could easily fit into a short length of 1/2" or 3/4" pvc pipe, and not set off walkthroughs.
Also considering midifying an usb external battery case, the 'lipstick' style ones look about right. Could maybe make a binder plug to usb A jack cable and a micro usb to 1/8" TRS cable. Then I could just toss it into the pass through with my phone.
Thoughts?
