I built something using an USB mp3 sound module and a bunch of LEDs. I replaced the included 200mah Lipo battery with a 1000mah one. The battery is recharged through the USB module.

All this sits in an enclosure that is mostly made of cardboard.

My question is: is it safe, or will it burn down the house of the person receiving this gift?
