Solar insect trap teardown - with schematic

This interesting device came from a store called Home Bargains, near to where I'm currently working. They actually have quite an interesting range of garden lighting and technical devices.

I think the main feature of this is that it's a beer trap which lures bugs in with a sweet yeasty smell. The blue solar powered LED may have some functionality, but it seems more of a gimmick. Especially with such a high inductor value in the boost circuit, which means it will not be bright.

I'd guess the main insects attracted by this trap will be wasps and flies. But I'm not sure if it'll be effective against biting insects that tend to home in on the warm moist carbon dioxide exhaled by humans and other mammals.

The design is fairly nice, and with a bit of extra waterproofing, the solar circuitry should last for a while. It's very hard to remove from the lid though, with very tight clips.
