I thought I might share my case option as others have kindly done.The yellow foam is, Yelofon used in construction to minimize sound transfer between units.

I have down loaded the Firmwire & Flash Application & saved these to my computer.(Windows 8), however I any not very techie & have no idea how to open a command window.Having down loaded the above, if I attach the Audio Moth will the computer see it?I had no problems with the initial set up. Help please.Regarding boxes I used a Sistema 200ml box measuring 115 x 90 x 40 mm (h), together with some foam cut to accommodate the Moth with a small hole for the microphone.These are air tight. Iwill use cling film to cover the mic hole.All assistance greatly appreciated.I am hoping to listen for bats.
