As the device is not totally weatherproof, and looks rather high-tech and appealing dangling from a tree, I set about maiking an enclosure to keep the weather off, and make it more discrete.
I started off with an plastic electronics enclosure box and cut a hole for the microphone. I then used that cut-off section as a shield above the microphone. The external power lead annoyingly comes out the front of the device which means you have to bend the lead back in to the battery pack.
For batteries I made a pack up from a 6xAA holder I got from Maplins. That should give about 7.2 V at 2500 mAH. The device only needs about 4 V to work, but six batteries should give some margin if a battery or two fails, which seems to be quite common for NiMH batteries, for me anyway.
